     This disclosure relates to a restraint system for a vehicle seat operatively mounted in a motor vehicle. The subject restraint system illustratively includes a number of different restraint structures and components, some non-limiting examples of which will be described in detail below. In the attached figures, the motor vehicle in which the vehicle seat and one or more of the restraint system components are to be mounted is represented in the form of example motor vehicle frame components or structures to which one or more structures of the vehicle seat and/or restraint system(s) are to be mounted. In some embodiments, the motor vehicle in which the vehicle seat and associated restraint system components are to be mounted is illustratively, but not exclusively, an off-road motor vehicle such as an all-terrain vehicle (ATV) or the like. It will be understood that the vehicle seat and/or one or more restraint components may alternatively be mounted within other motor vehicles without limitation. It will be further understood that whereas the vehicle seat and associated restraint system is illustrated in the attached drawings and described below as including multiple different occupant and vehicle seat restraint components, the illustrated seat or other motor vehicle seat may alternatively be outfitted with only a single one or any combination of any of the multiple different occupant and/or vehicle seat restraint components described herein by example. 
     Referring now to  FIGS. 1-3 , an embodiment of a vehicle seat  10  operatively mountable in a motor vehicle and an occupant restraint system  12  therefor is shown. In the illustrated embodiment, the vehicle seat  10  includes a seat base  14  mountable to a floor or floor frame of a motor vehicle. In the illustrated embodiment, the floor or floor frame of the motor vehicle is represented by a floor or floor frame component  16 A, and a rear structure or frame of the motor vehicle rearwardly of the floor frame component  16 A is represented be a rear frame component  16 B. In any case, the seat base  14  is illustratively movably coupled to a seat bottom module  18  which is coupled to a seat back module  20  extending upwardly and away from the seat bottom module  18 . 
     The seat base  14  is may be conventional and may include conventional structure(s) for pivoting, i.e., folding, the seat  10  forwardly, e.g., so as to allow for ingress to and exit from a portion of the motor vehicle rearwardly of the seat  10 , and/or for sliding the vehicle seat  10  fore and/or aft to selectively position the vehicle seat  10  relative to the motor vehicle. In this regard, a non-limiting embodiment of a seat base  14  is illustrated by example in  FIG. 2 . Referring to  FIG. 2 , the example seat base  14  illustratively includes a pivoting mounting plate assembly  22  having face-to-face lower and upper plates  22 A,  22 B, wherein the lower plate  22 A is affixed to the floor or floor frame component  16 A, e.g., by conventional fixation elements. The upper plate  22 B is illustratively affixed to elongated seat adjustment tracks  24 A,  24 B respectively disposed along opposite sides of the vehicle seat  10  and both extending at least partially between the front and rear of the vehicle seat  10 . Complementary elongated seat adjustment tracks  32 A,  22 B are affixed to respective frame components  30 A,  30 B of the vehicle seat  10 . The tracks  24 A,  24 B and the tracks  32 A,  32 B are configured to slidingly engage one another such that the track  32 A is movable along the track  24 A and the track  32 B is movable along the track  24 B. The tracks  24 A,  24 B and  32 A,  32 B illustratively include a conventional locking mechanism which is operatively coupled to a lever (not shown) for slidably positioning the tracks  24 A,  24 B, and thus selectively positioning the seat  10 , fore and aft relative to the tracks  32 A,  32 B to any of a range of positions between a maximum forward position and a maximum rearward position. 
     The lower plate  22 A and the upper plate  22 B are hingedly and pivotably coupled to one another via a pair of hinges  25 A,  25 B positioned along the front of the seat bottom module  14 . The lower plate  22 A of the mounting plate assembly  22  is thus hingedly coupled to the upper plate  22 B along the front of the seat bottom module  18 . As illustrated by example in  FIGS. 11B, 15A and 15B , the vehicle seat  10  is illustratively pivotable about the hinges  25 A,  25 B such that the vehicle seat  10  is pivotable forwardly from an occupant support position in which the plates  22 A,  22 B are face-to-face and, in some embodiments, in contact with one another along their opposing faces, to any of a range of forwardly tilted positions in which the opposed faces of the plates  22 A,  22 B are separated from one another and form an angle therebetween relative to the hinges  25 A,  25 B. In the forward tilted position of the vehicle seat  10 , access may be had, for example, to a rear seat or rear compartment of the motor vehicle. The vehicle seat  10  is pivotable about the hinges  25 A,  25 B from any such position back to the occupant support position illustrated in  FIGS. 1A-2 , wherein the plate  22 A remains affixed to the floor frame component  16 A and the plate  22 B travels with the seat  10 . 
     It bears pointing out that the embodiment of the seat base  14  illustrated in  FIG. 2  and described above is provided only by way of example, and is not intended to be limiting in any way. Those skilled in the art will recognize other configurations of the seat base  14  that may be used to mount the vehicle seat  10  to a motor vehicle, and it will be understood that any such other seat base configurations are intended to fall within the scope of this disclosure. Some such alternate embodiments may be configured to be slidably positionable fore and/or aft only (i.e., not pivotable), some may be configured to be pivotable only (i.e., not slidably positionable) and some may be configured to be both slidably positionable and pivotable as just described. 
     The seat bottom module  18  illustratively includes a seat module base  34  secured to the frame components  30 A,  30 B of the vehicle seat  10 .

In the illustrated embodiment, the cushions  38 ,  40 A,  40 B and  52 E- 52 I are all non-detachably affixed to their respective structures, although in alternate embodiments one or more such cushions may be detachable so as to be replaceable and/or repositionable. The seat back panel  50  is illustratively a rigid material, as is the seat module base  34  and the occupant seat panel  36 , and in one embodiment such components are made of one or more conventional rigid plastic materials. In some embodiments, one or more of the seat back panel  50 , the seat module base  34  and the occupant seat panel  36  may be structurally reinforced using one or more conventional reinforcing materials. In some embodiments, the upper wings  48 E/ 50 E,  48 G/ 50 G and/or the lower wings  48 F/ 50 F,  48 H/ 50 H may be adjustable, e.g., vertically, horizontally and/or semi-flexibly positionable. 
     The occupant restraint system  12  is a multi-point restraint system and in this regard the restraint system  12  may be configured to have two or more points of restraint. In the illustrated embodiment, the restraint system  12  is a 6-point restraint system, although in alternate embodiments the restraint system  12  may be configured to have more or fewer points of restraint. Referring to  FIGS. 1A and 1B  in particular, the illustrated occupant restraint system  12  includes two shoulder webs  60 A,  60 B each extending through a respective one of the openings  56 A,  56 B in the shoulder web guide plate  56 . One end of each web  60 A,  60 B extends and downwardly along the rear surface of the seat back module  20  and is illustratively coupled to a Y-connector  62 . One end of another web  60 C is also coupled to the Y-connector  62  and an opposite end is operatively coupled to a conventional web retractor  64  mounted to the seat back frame  48  adjacent to the seat base  14 . In alternate embodiments, the Y-connector  62  may be omitted and each of the shoulder webs  60 A,  60 B may be coupled to a respective one of two conventional web retractors mounted to the seat back frame  48 . As depicted by example in  FIG. 1B , mounting structures  66 A,  66 B are provided on the seat back frame  48  for this purpose. The web retractors  64  (or two web retractors in alternate embodiments) are illustratively conventional inertial locking retractors. In one embodiment, the web retractor  64  is provided in the form of conventional automatic locking retractor (ALR), although in alternate embodiments the web retractor  64  may be provided in the form of a conventional emergency locking retractor (ELR) or other suitable inertial locking retractor. 
     The opposite ends of the webs  60 A,  60 B are each coupled to a respective one of a pair of web attachments members  68 A,  68 B. Between the web attachment members  62 A,  62 B and the web retractor  64 , the shoulder webs  60 A,  60 B each pass through the guide plate  56  as described above, and each is supported on and by a respective one of the shoulder web attenuators  58 A,  58 B. The shoulder web attenuators  58 A,  58 B are each illustratively configured to attenuate movement of the shoulder webs  60 A,  60 B during operation of the motor vehicle as will be described in detail below. The shoulder web  60 A thus extends upwardly from the Y-connector  62  along the back side of the seat back module  20 , through the web attenuator  58 A, through the seat back panel  50  and then downwardly along the front side of the seat back module  20  and into engagement with the web attachment member  68 A. The shoulder web  60 B likewise extends upwardly from the Y-connector  62  along the back side of the seat back module  20 , through the web attenuator  58 B, through the seat back panel  50  and then downwardly along the front side of the seat back module  20  and into engagement with the web attachment member  68 B. The shoulder webs  60 A,  60 B thus run substantially parallel with and spaced apart from one another so as to extend over respective shoulders and downwardly along a torso of an occupant seated in the vehicle seat  10 . 
     Adjacent to the front portion of the seat back panel  50  through which the shoulder webs  60 A,  60 B pass, the shoulder web  60 A passes through an elongated web sleeve or pad  78 A and the shoulder web  60 B likewise passes through another elongated web sleeve or pad  78 B. A cross strap  76  is illustratively affixed to the shoulder web  60 A between the sleeve or pad  78 A and the web attachment member  68 A, and the cross strap  92  is configured to be releasably secured to the shoulder web  60 B as illustrated by example in  FIG. 1A . The positions of the web sleeves  78 A,  78 B relative to the shoulder webs  60 A,  60 B are illustratively each independently adjustable along a respective one of the shoulder webs  60 A,  60 B as will be described in detail below with respect to  FIGS. 4-6B . 
     The illustrated occupant restraint system  12  further includes two lap webs  72 A,  72 B each coupled at one end to a respective one of the web attachment members  68 A,  68 B. The lap webs  72 A,  72 B each extend through the occupant support panel  36  and into engagement with the ratcheting web adjustment apparatus  140  as will be described in detail below. In the illustrated embodiment, the lap webs  72 A,  72 B comprise a single length of web operatively coupled to apparatus  140 , although in other embodiments the lap webs  72 A,  72 B may be separate from one another. 
     The illustrated occupant restraint system  12  further includes two thigh restraint webs  74 A,  74 B each coupled at one end to a respective one of the web attachment members  68 A,  68 B. The thigh webs  74 A,  74 B each extend through the occupant support panel  36  and into engagement with the ratcheting web adjustment apparatus  140  as will be described in detail below. In the illustrated embodiment, the thigh webs  74 A,  74 B comprise a single length of web operatively coupled to apparatus  140 , although in other embodiments the thigh webs  74 A,  74 B may be separate from one another. Operation of the ratcheting web adjustment apparatus will be described in detail below with respect to  FIGS. 7-9 . 
     The restraint system  12  further includes engagement members  70 A,  70 B mounted to or integral with respective ones of the web attachment members  68 A,  68 B. In the illustrated embodiment, the engagement member  70 A is or includes a conventional tongue and the engagement member  70 B is or includes a conventional buckle, wherein the tongue of the tongue member  70 A is releasably engageable with and to the buckle of the buckle member  70 B. In some alternate embodiments, the engagement member  70 A may be the buckle member and the engagement member  70 B may be the tongue member. In any case, the engagement members  70 A,  70 B are releasably engageable with and to one another to releasably couple the web attachment members  68 A,  68 B together as illustrated in  FIG. 1A . 
     Referring now to  FIG. 3 , an embodiment of the web attenuators  58 A,  58 B is illustrated by example, along with an engagement assembly  80  configured to releasably engage an embodiment of a seat restraint system for restraining movement, e.g., pivoting and forward sliding, of the vehicle seat  10 . Embodiments of the seat restraint system will be described in detail below with respect to  FIGS. 10-12 . The engagement assembly  80  illustratively includes a bracket or plate  82  mounted flush to the rear surface of the headrest panel  55 . Coupled to or integral with the bracket or plate  82  is a tongue member  84  which extends generally rearwardly away from the rear surface of the headrest  55 . In the illustrated embodiment, the tongue member  84  extends from the top end of the bracket or plate  82  at a generally acute angle relative to vertical, although in alternate embodiments this angle may be non-acute. In any case, the tongue member  84  is conventional and is configured to releasably engage a conventional buckle member forming part of the seat restraint system as will be described below with respect to  FIGS. 10-12 . In alternate embodiments, the buckle member may be coupled to the bracket or plate  82  and the tongue member  84  may form part of the seat restraint system. 
     In the embodiment illustrated in  FIG. 3 , the web attenuators  58 A,  58 B each operatively mounted to the seat back module  20  and are each illustratively configured to independently attenuate downward movement of a respective one of the shoulder webs  60 A,  60 B, i.e., downward movement of the web(s)  60 A and/or  60 B toward the shoulders of the seat occupant, during operation of the motor vehicle in which the vehicle seat  10  is mounted. In the illustrated embodiment, and referring also to  FIG. 4 , the guide plate  56  defines laterally spaced apart openings  56 A,  56 B therethrough just below the head rest panel  55  through which the shoulder webs  60 A,  60 B extend as described above. The web attenuator  58 A illustratively includes opposing brackets  86 A and  88 A mounted to the headrest  55  alongside respective opposing sides of the opening  56 A defined through the guide plate  56 . The web attenuator  58 B likewise illustratively includes opposing brackets  86 B and  88 B mounted to the headrest  55  alongside respective opposing sides of the opening  56 B defined through the guide plate  56 . In the illustrated embodiment, the brackets  86 A,  86 B are integral with the bracket  82  such that the brackets  82 ,  86 A and  86 B are of uniform construction. In alternate embodiments, the bracket  86 A and/or the bracket  86 B may be separate from the bracket  82 . In any case, the brackets  86 A,  88 A and  86 B,  88 B are illustratively parallel with one another and each extends rearwardly from the headrest panel  55  on opposite sides of the respective openings  56 A,  56 B. The brackets  86 A,  88 A each define respective opposed slots or channels  92 A,  94 A each illustratively extending at an acute angle relative to vertical from a lower portion of the respective bracket  86 A,  88 A upwardly to a mid-portion of the respective bracket  86 A,  88 A. The brackets  86 B,  88 B likewise each define respective opposed slots or channels  92 B,  94 B each illustratively extending at an acute angle relative to vertical from a lower portion of the respective bracket  86 B,  88 B upwardly to a mid-portion of the respective bracket  86 B,  88 B. 
     A rod or shaft  90 A is mounted to and between the brackets  86 A,  88 A adjacent to or near a top of the opening  56 A, and a rod or shaft  90 B is likewise mounted to and between the brackets  86 B,  88 B adjacent to or near the opening  56 B. Opposing ends of another rod or shaft  96 A are received within respective slots  92 A,  94 A of the brackets  86 A,  88 A, and opposing ends of yet another rod or shaft  96 B are received within respective slots  92 B,  94 B of the brackets  86 B,  88 B. The rod or shaft  96 A thus extends transversely across the opening  56 A between the two brackets  86 A,  88 A, and is movable along the slots  92 A,  94 A between the terminal ends of the slots  92 A,  94 A. The rod or shaft  96 B likewise extends transversely across the opening  56 B between the two brackets  86 B,  88 B, and is movable along the slots  92 B,  94 B between the terminal ends of the slots  92 B,  94 B. A resilient member  98 A is coupled between the rod or shaft  90 A and the rod or shaft  96 A at or near respective ends thereof adjacent to an outer surface of the bracket  88 A, and another resilient member  98 B is coupled between the rod or shaft  90 A and the rod or shaft  96 A at or near respective opposite ends thereof adjacent to an outer surface of the bracket  86 A, wherein the outer surfaces of the brackets  86 A,  88 A are those facing away from each other and away from the opening  56 A. Another resilient member  98 C is coupled between the rod or shaft  90 B and the rod or shaft  96 B at or near respective ends thereof adjacent to an outer surface of the bracket  88 A, and still another resilient member  98 D is coupled between the rod or shaft  90 B and the rod or shaft  96 B at or near respective opposite ends thereof adjacent to an outer surface of the bracket  86 B, wherein the outer surfaces of the brackets  86 B,  88 B are likewise those facing away from each other and away from the opening  56 B. Although the rod or shaft  90 A acts to securely couple the brackets  86 A,  88 A to one another and the rod or shaft  90 B likewise acts to securely couple the brackets  86 B,  88 B to one another, it is not essential to the functionality of the web attenuators  58 A,  58 B to extend the rods or shafts  90 A,  90 B transversely between the respective brackets. In some alternate embodiments, then, the rods or shafts  90 A,  90 B may be replaced with simple structures mounted to or integral with the outer surfaces of the brackets  86 A,  86 B,  88 A,  88 B suitable for securing a respective one of the resilient members  98 A- 98 D thereto. 
     The resilient members  98 A- 98 B illustratively operate to suspend the rods or shafts  96 A,  96 B from the ends of the respective rods or shafts  90 A,  90 B such that the rod or shaft  96 A is moveable within the slots  92 A,  94 A under bias of the resilient members  98 A,  98 B and the rod or shaft  96 B is moveable within the slots  92 B,  94 B under bias of the resilient members  98 C,  98 D. As illustrated in  FIGS. 3 and 4 , the shoulder web  60 A extends through the opening  56 A of the guide plate  56  and is supported by the rod or shaft  96 A suspended from the ends of the rod or shaft  90 A by the resilient members  98 A,  98 B, and the shoulder web  60 B extends through the opening  56 B of the guide plate  56  and is supported by the rod or shaft  96 B suspended from the ends of the rod or shaft  90 B by the resilient members  98 C,  98 D. The resilient members  98 A,  98 B and  98 C,  98 D operate to attenuate downward forces applied by the shoulder webs  60 A,  60 B to the respective rods or shafts  96 A,  96 B under dynamic operating conditions of the motor vehicle in which the vehicle seat  10  is mounted. Illustratively, the resilient force of the of the resilient members  98 A- 98 D, i.e., the amount of downward force required to be applied by the respective webs  60 A,  60 B between the rods or shafts  90 A,  90 B and the rods or shafts  96 A,  96 B to move the rods or shafts  90 A,  90 B a unit distance from one another within the respective slots  92 A,  94 A and  92 B,  94 B, may be selected based on the application. In some embodiments, for example, resilient members  98 A- 98 D of different resilient force may be readily available, and may be selected accordingly. Alternatively or additionally, multiple resilient members  98 A- 98 D per bracket side may be used in either or both of the web attenuators  58 A,  58 B to achieve a desired resilient force. 
     In the illustrated embodiment, the resilient members  98 A- 98 D are provided in the form of O-rings or rings of other shapes formed of one or more suitable resilient materials such as rubber, latex, or the like. In other embodiments, the resilient members  98 A- 98 D may be provided in the form of linear, non-linear or piecewise liner shapes of one or more conventional resilient materials. In some such alternate embodiments, the one or more conventional biasing members may be or include one or more conventional springs, e.g., one or more linear or non-linear coil springs, flat springs and/or wire forms embodied as one or more compression springs, one or more extension springs, one or more torsion springs, one or more constant force springs or the like, or any combination thereof. Alternatively or additionally, the one or more biasing members may be or include one or more conventional shock absorbing or shock dampening devices, e.g., such as one or more conventional dashpots, of hydraulic, pneumatic and/or mechanical design. In any case, the one or more biasing members may be selected or designed to have any desired linear or non-linear, constant or non-constant, biasing force(s) to achieve any desired dampening or spring rate. 
     It will be noted that the acute angle defined by the opposed pairs of slots  92 A,  94 A and  92 B,  94 B is selected to at least approximately match an angle at which the shoulder webs  60 A,  60 B exit the openings  56 A,  56 B of the guide plate  56  due to the shoulder webs  60 A,  60 B, in operation, being forced horizontally away from the front surface of the seat back module  20  by a distance corresponding to the thickness of the torso of the seat occupant. In one embodiment, the acute angle is selected to match an approximate torso thickness of an average sized occupant. Other applications will require other considerations as to the angle relative to vertical, if any, of the slots  92 A,  94 A and  92 B,  94 B. 
     Referring now to both  FIG. 3  and  FIG. 4 , the shoulder web  60 B illustratively represents static operating conditions of the motor vehicle in which the vehicle seat  10  is mounted and of the occupant being restrained by the restraint system  12 . Under such static operating conditions, the vehicle is not imparting any movement to the seat  10 , the occupant or the shoulder web  60 B, and the occupant is stationary and seated normally in the vehicle seat  10  so as to not impart any outward or other forces on the shoulder web  60 B. Under such conditions, no downward force is being applied by the shoulder web  60 B to the rod or shaft  96 B and the resilient members  98 C,  98 D are therefore unstretched. In this example, the dimensions and resilient force of the resilient members  98 C,  98 D have been selected such that, under such static conditions, the rod or shaft  96 B supporting the shoulder web  60 B thereon is at or near the top of the opening  56 B defined through the guide plate  56 . In other embodiments, the resilient members  98 C,  98 D may be selected so as to place the rod or shaft  96 B supporting the shoulder web  60 B at any desired position within the opening and relative to the rod or shaft  90 B. 
     The shoulder web  60 A in  FIGS. 3 and 4  illustratively represents a dynamic operating condition of the motor vehicle in which the vehicle seat  10  is mounted and/or of the occupant being restrained by the restraint system  12 . Under such a dynamic operating condition, caused by the terrain being traversed by the motor vehicle, an impact of the motor vehicle with another object, or simply by erratic movement of the occupant of the vehicle seat  10 , substantial downward force is being applied by the shoulder web  60 A to the rod or shaft  96 A which has caused the rod or shaft  96 A to travel to the terminal ends of the slots  92 A,  94 A and stretch, i.e., elongate, the resilient members  98 C,  98 D in the process. Between the two extremes illustrated by example in  FIGS. 3 and 4 , some dynamic operating conditions may cause the webs  60 A,  60 B to exert various downward forces on the rods or shafts  96 A,  96 B which will temporarily cause the resilient members  98 A,  98 B and/or the resilient members  98 C,  98 D to temporarily stretch, i.e., elongate, but to then return to their static positions once the dynamic operating condition has passed. 
     In the illustrated embodiment, each rod or shaft  96 A,  96 B is movable therein between an upper and lower positions thereof as defined by the dimensions of the respective slots  92 A,  94 A and  92 B,  94 B and the resilient force and dimensions of the resilient members  98 A- 98 D. In the illustrated embodiment, the slots  92 A,  94 A and  92 B,  94 B are linear and the rods or shafts  96 A,  96 B accordingly move linearly therein. In other embodiments, the slots  92 A,  94 A and/or  92 B,  94 B be non-linear or piece-wise linear, and movement the rods or shaft  96 A,  96 B in such embodiments will move non-linearly or piecewise linearly therein. In one embodiment, the rods or shafts  96 A,  96 B are each illustratively biased upwardly within the respective openings  56 A,  56 B, such that with no downward force applied either of the shoulder webs  60 A,  60 B the rods or shafts  96 A,  96 B are both in their upper positions as illustrated by the rod or shaft  96 B in  FIGS. 3 and 4 . A downward force applied to either or both of the shoulder webs  60 A,  60 B in excess of the upwardly directed biasing force drives the respective rod or shaft  96 A,  96 B downwardly against the biasing force at least partially toward the lower position(s) of the rods or shafts  96 A,  96 B relative to the slots  92 A,  94 A and/or  92 B,  94 B. A downward force of sufficient magnitude applied to either or both of the shoulder webs  60 A,  60 B will drive the respective rod or shaft  96 A,  96 B downwardly against the biasing force to the lowest position(s) of the rod or shaft(s)  96 A,  96 B relative to the slots  92 A,  94 A and/or  92 B,  94 B. The upwardly directed biasing force applied by the resilient members  98 A- 98 D to the rods or shafts  96 A,  96 B thus acts to attenuate forceful downward movement of the respective shoulder webs  60 A,  60 B, thereby absorbing at least some amount of the shock force applied to the shoulder webs  60 A,  60 B during various dynamic operating conditions of the motor vehicle in which the vehicle seat  10  is mounted. In some alternate embodiments, the rods or shafts  96 A,  96 B may be biased to a “center” position between their upper and lower positions. In such embodiments, pairs of the rods or shafts  96 A,  96 B may positioned in the slots  92 A,  94 A and  92 B,  94 B with the shoulder webs  60 A,  60 B passing between each respective set and with each pair biased both upwardly and downwardly against the brackets  86 A,  88 A and/or  86 B,  88 B such that a downward force of sufficient magnitude applied to either or both of the shoulder webs  60 A,  60 B will drive the respective rod or shaft  96 A,  96 B downwardly against the biasing force toward or to the lower position(s) thereof, and such that an upward force of sufficient magnitude applied to either or both of the shoulder webs  60 A,  60 B will drive the respective rod or shaft  96 A,  96 B upwardly against the biasing force toward or to the upper position(s) thereof. 
     It will be understood that in embodiments of the vehicle seat  10  in which the shoulder webs  60 A,  60 B do not pass through the seat back module  20  but instead pass over the top of the seat back module  20 , e.g., on either side of the head rest  55 , the shoulder web attenuators  58 A,  58 B may be mounted to the seat back module  20  in a manner that positons them above the top of the seat back panel  50  on either side of the head rest panel  55 . 
     Referring now to  FIGS. 4-6 , the web sleeves  78 A,  78 B are each independently adjustable along a respective one of the shoulder webs  70 A,  70 B to selectively position a respective sleeve  78 A,  78 B relative to a shoulder of an occupant of the vehicle seat  10  and/or relative to the seat back  20 . In the illustrated embodiment, the web sleeves  78 A,  78 B are elongated sleeves each having one respective end  78 A 1 ,  78 B 1  facing toward the cross strap  76  and an opposite respective end  78 A 2 ,  78 B 2  facing toward the web guide plate  56  (or other structure which defines the front surface of the seat back module  20  into which the shoulder webs  60 A,  60 B extend). 
     Each web sleeve  78 A,  78 B includes a respective sleeve position adjuster  100 A,  100 B operatively coupled thereto and illustratively positioned adjacent to a respective end  78 A 1 ,  78 B 1  thereof. In alternate embodiments, the sleeve position adjuster  100 A and/or the sleeve position adjuster  100 B may be positioned elsewhere along the respective web sleeve  78 A,  78 B. Each sleeve position adjuster  100 A,  100 B includes a housing  102 A,  102 B mounted, i.e., attached, affixed or otherwise secured to a respective one of the web sleeves  78 A,  78 B, and an actuator  104 A,  104 B, e.g., in the form of a button, lever or other conventional actuator, which is manually actuatable between a normal, unactuated position in which the actuator  104 A,  104 B engages a portion of a respective one of the shoulder webs  60 A,  60 B to secure, i.e., clamp, the portion of the shoulder web  60 A,  60 B and thus fix the position of the sleeve  78 A,  78 B relative to the shoulder web  60 A,  60 B, and an actuated position in which the actuator  104 A,  104 B disengages from the shoulder web  60 A,  60 B to thus allow the sleeve  78 A,  78 B to be moved along the respective shoulder web  60 A,  60 B. In the unactuated or clamped position of the actuator  104 A, the position of the respective actuator  104 A,  104 B, and thus the position of the respective web sleeve  78 A,  78 B, relative to the respective shoulder web  60 A,  60 B, is fixed. In the actuated or unclamped position of the actuator  104 A,  104 B, the respective actuator  104 A,  104 B, and thus the respective web sleeve  78 A,  78 B is movable, e.g., slidable, along the respective shoulder web  60 A,  60 B so as to be adjustably positionable relative to the respective shoulder web  60 A,  60 B. 
     Referring to  FIGS. 6A and 6B , an embodiment of the sleeve position adjuster  100 A,  100 B (illustrated with respect to the adjuster  100 B) is shown in cross section.  FIG. 6A  depicts the unactuated, or clamped, positon of the actuator  104 A, and  FIG. 6B  depicts the actuated, or unclamped position of the actuator  104 A. In the illustrated embodiment, the housing  102 B of the sleeve positon adjuster  100 B includes an upper housing member  106  which defines an opening  108  sized to receive the actuator  104 B therein. An upper wall  110  runs substantially parallel with the housing member  106  and defines an opening  112  sized to receive a web clamping portion  128  of the actuator  104 B therein. A space S 1  is defined between the housing member  106  and the upper wall  110 , and the width of the space S 1  is selected so as to receive a wall of the sleeve  78 B therein as shown. A lower wall  112  runs substantially parallel with the upper wall  110  and defines an opening  116  that aligns with the opening  112  in the upper wall. In one embodiment, the openings  112  and  116  are dimensionally the same and are juxtaposed relative to one another. In alternate embodiments, the openings  112  and  116  may have different dimensions and/or may be at least partially offset from one another. In any case, a space S 2  is defined between the upper and lower walls  110 ,  114  having a width selected so as to receive the thickness of the shoulder web  60 B therethrough as shown. The sum of the widths of the spaces S 1  and S 2 , taking into account the thicknesses of the upper and lower walls  110 ,  112 , to be received with the inner space  78 B S  defined by the sleeve  78 B. In the illustrated embodiment, the sleeves  78 A,  78 B are configured to be closed structures defining inner spaces that wrap completely around or about the shoulder webs  60 A,  60 B. In alternate embodiments, the sleeve  78 A and/or the sleeve  78 B may be configured to wrap only partially about the shoulder web(s)  60 A and/or  60 B. 
     The actuator  104 B illustratively includes a lever portion  120  that is sized to be received within the opening  108 . A post  122  extends downwardly from the lever  120  and receives a biasing member  124  positioned between the lever portion  120  and a top surface of the upper wall  110 . The web clamping portion  128  of the actuator  104 B extends downwardly from one end of the lever portion  120  and into the aligned openings  112 ,  116  as illustrate in  FIG. 6A  in the unactuated position of the actuator  104 B. In some embodiments, teeth  130  are provided at the terminal end of the web clamping portion  128  to facilitate clamping engagement of the actuator  104 B with the shoulder web  60 B. In some embodiments, as illustrated by example in  FIG. 6A , the actuator  104 B includes a stop  126  sized to contact the top surface of the upper wall  110  in the clamped position of the actuator  104 B to limit the depth of penetration of the web clamping portion into the aligned openings  112 ,  116 . The actuator  104 B is illustratively configured such that the exposed end of the lever portion  120  protrudes upwardly out of the opening  108  in the unactuated positon of the actuator  104 B, although in other embodiments the lever portion  120  may be flush with or recessed within the opening  108 . 
     In the unactuated or clamped position of the actuator  104 B, the biasing member  124  exerts an upward biasing force to the underside of the lever portion  120  at or near the free end thereof which drives the clamping portion  128  of the actuator  104 B into and through the aligned openings  112 ,  116  and into engagement with the shoulder web  60 B as illustrated by example in  FIG. 6A . The biasing force of the biasing member  124  is illustratively selected so as to cause the clamping portion  128  of the actuator  104 B to drive a portion  60 B P  of the shoulder web  60 B at least partially into the opening  116 , thereby effectively trapping the portion  60 B P  of the shoulder web  60 B in the opening  116  and fixing the position of the actuator  104 B, and thus of the sleeve position adjuster  100 B and the sleeve  78 B, relative to the shoulder web  60 B. In the actuated or clamped position of the actuator  104 B, a downward force is applied to the free end of the lever portion  120  that is of sufficient magnitude to overcome the biasing force of the biasing member  124 . This downward force moves the free end of the lever portion  120  into the opening  108 , thereby driving the clamping portion  128  upwardly and away from the opening  116  as illustrated by example in  FIG. 6B . In this position, the clamping portion  128  of the actuator  104 B is disengaged from the shoulder web  60 B, and the sleeve position adjuster  100 B as well as the sleeve  78 B may therefore be moved along the shoulder web  60 B. In some embodiments, the clamping portion  128  may remain in contact with the shoulder web  60 B in the actuated or unclamped position of the actuator  104 B, but in such embodiments any force applied by the clamping portion to the shoulder web  60 B is not sufficient to prevent movement of the sleeve position adjuster  100 B, and thus the sleeve  78 B, along the shoulder web  60 . For purposes of this disclosure, then, the phrase “the clamping portion  128  of the actuator  104 B is disengaged from the shoulder web  60 B” when used in the context of the actuated or unclamped position of the actuator  104 B will be understood to mean that the clamping portion  128  may not be in contact with the shoulder web or that the clamping portion  128  may be in contact with the shoulder web  60 B but not with sufficient force to prevent movement of the actuator  104 B and the sleeve  78 B relative to the shoulder web  60 B. 
     Referring again to  FIGS. 4 and 5 , the sleeve  78 B is shown in a lower position relative to the shoulder web  60 B in  FIG. 4 , i.e., with the end  78 B 1  adjacent to the cross strap  76 . In  FIG. 5 , the actuator  104 B of the sleeve position adjuster  100 B has been manually moved from the normal unactuated, clamped position to the actuated, unclamped position and, with the actuator  104 B maintained in the actuated position, the sleeve  78 B has been moved upwardly along the shoulder web  60 B to position the end  78 B 2  adjacent to the opening  56 B in the guide plate  56 . Thereafter, the actuator  104 B was released, which caused the actuator  104 B to automatically return to the unactuated, clamped position thereof to fix the position of the sleeve  78 B relative to the shoulder web  60 B. 
     It will be understood that whereas the web sleeves  78 A,  78 B are illustrated in the attached figures and described above as being received on the shoulder webs  60 A,  60 B of the restraint system  12 , either or both of the web sleeves  78 A,  78 B may alternatively or additionally be provided on any of the webs or pairs of webs of the restraint system  12 . 
     Referring now to  FIGS. 7-9 , operation of the ratcheting web adjustment apparatus  140  will be described. As briefly described above, the ratcheting web adjustment apparatus  140  is configured to selectively (and independently) tighten, i.e., by reducing the length of, the lap web(s)  72 A,  72 B and/or the thigh web(s)  74 A,  74 B. In this regard, the apparatus  140  illustratively includes at least two manually ratcheting web retractors operatively mounted therein. Each such manually ratcheting web retractor is illustratively conventional and includes a spool about which a web is wound, at least one toothed gear or wheel mounted to rotate with the spool and a conventional locking mechanism, e.g., a conventional locking pawl which, when engaged with the at least one toothed gear or wheel (i.e., in its locked position), prevents rotation of the spool in the web payout direction but allows manual ratcheting of the spool in the web take-up direction to incrementally take up web on the spool while also preventing payout of the web such that the web is tightened by reducing its length. Each such ratcheting web retractor is further rotationally biased in the web take-up direction such that, when the locking mechanism is disengaged from the at least one toothed gear or wheel (i.e., in its unlocked position), the spool rotates under the bias in the web take-up direction to automatically take up web on the spool. With the locking mechanism disengaged, i.e., unlocked, the spool can be made to rotate in the web payout direction by applying a force to the web in the web payout direction that is greater than the biasing force to thereby pay out web from the retractor. 
     In the illustrated embodiment, the ratcheting web adjustment apparatus  140  includes two ratcheting web retractors of the type just described. One is coupled via at least one web to the lap web(s)  72 A,  72 B, and the locking/release mechanism thereof is operatively coupled to the release lever  42 . The at least one toothed gear or wheel of this ratcheting web retractor is operatively coupled to the manually actuatable lever  44 A mounted on one side of the seat module base  34 . In some alternate embodiments, the at least one toothed gear or wheel of this ratcheting web retractor may instead be operatively coupled to the manually actuatable lever  44 B mounted on the opposite side of the seat module base  34 . The lap web  72 A illustratively enters and exits the seat module base  34  via a slot  3662  defined through a top edge  36 B 1  of the side wall  36 B of the occupant seat panel  36 , and the lap web  72 B illustratively enters and exits the seat module base  34  via a slot  36 C 2  defined through a top edge  36 C 1  of the side wall  36 C of the occupant seat panel  36 , as illustrated by example in  FIG. 7 . The other ratcheting web retractor is coupled via at least one web to the thigh web(s)  74 A,  74 B, and the locking mechanism thereof is also operatively coupled to the release lever  42 . The at least one toothed gear or wheel of this ratcheting web retractor is operatively coupled to the manually actuatable lever  44 B mounted on one side of the seat module base  34 , although in some alternate embodiments the at least one toothed gear or wheel of this ratcheting web retractor may instead be operatively coupled to the manually actuatable lever  44 A mounted on the opposite side of the seat module base  34 . The thigh web  74 A illustratively enters and exits the seat module base  34  via a slot  36 B 3  defined through the top edge  36 B 1  of the side wall  36 B of the occupant seat panel  36 , and the thigh web  74 B illustratively enters and exits the seat module base  34  via a slot  36 C 3  defined through the top edge  36 C 1  of the side wall  36 C of the occupant seat panel  36 , as illustrated by example in  FIG. 7 . 
     The release lever  42  is illustratively operable to simultaneously control the locking states of the locking mechanisms of each ratcheting web retractor of the apparatus  140 . In the default position of the lever  42  illustrated in  FIGS. 1 and 7 , the locking mechanism are in their locked positions to thereby prevent rotation of the web spools in the web payout direction. The lever  42  may be manually actuated, e.g., by pulling upwardly on the lever  42 , to cause both locking mechanisms to move to their unlocked positions, thereby allowing web payout from and web retraction within the respective retractors. Upon release of the lever  42 , it illustratively returns to the position shown in  FIGS. 1 and 7  which simultaneously causes both locking mechanisms to move back to their locked positions, thereby preventing web payout from the respective retractors. It will be understood that the lever  42  may take other conventional forms, and/or be located elsewhere on the vehicle seat  10 . In some embodiments, the lever  42  may be provided in the form of two separate levers; one for controlling the locking state of one of the retractors and one for controlling the locking state of the other retractor. 
     The manually actuatable levers  44 A,  44 B are each configured to be manually actuated in a manner that causes incremental rotation of the toothed gear(s) of a respective one of the ratcheting web retractors of the apparatus  140  to thereby take up slack, i.e., reduce the length of, the respective web coupled to the respective lap web(s)  72 A,  72 B or thigh web(s)  74 A,  74 B, thereby reducing or displacing the length thereof in a manner which tightens the respective lap web(s)  72 A,  72 B or thigh web(s)  74 A,  74 B about the occupant. In one embodiment of the apparatus  140  in which the lap webs  72 A,  72 B are provided in the form of a single length of web and in which the thigh webs  74 A,  74 B are likewise provided in the form of a single length of web, ratcheting of one of the ratcheting web retractor mounted in the seat module base  34  reduces the length of a web coupled to the single lap web which, in turn, displaces a portion of the single lap web within the seat module base  34 , thereby tightening the single lap web about the lap of the occupant of the vehicle seat  10 . Likewise, ratcheting of the other ratcheting web retractor mounted in the seat module base  34  reduces the length of another web coupled to the single thigh web which, in turn, displaces a portion of the single thigh web within the base  34 , thereby tightening the single thigh web about the thighs of the occupant of the vehicle seat  10 . In some alternate embodiments, the apparatus  140  may be configured such that ratcheting of one or more web retractors causes shortening, and therefore tightening, of the one or more lap webs  72 A,  72 B and such that ratcheting of one or more other web retractors causes shortening, and therefore tightening, of the one or more thigh webs  74 A,  74 B. 
     In any case, each manually actuatable lever  44 A,  44 B is operatively coupled to the toothed gear(s) or wheel(s) of a respective ratcheting web retractor of the apparatus, and is configured to be manually actuated in a manner which causes incremental rotation of the respective toothed gear(s) or wheel(s) in the web take-up direction, thereby tightening a respective one of the lap web(s)  72 A,  72 B and the thigh web(s)  74 A,  74 B about the occupant. In the illustrated embodiment, each lever  44 A,  44 B is rotatable about a respective pivot point  46 A,  46 B between a lower position, and an upper position. In some embodiments, the lower position is the default position, and each lever  44 A,  44 B is illustratively biased to the lower position. Alternatively, the upper position may be the default position and each lever  44 A,  44 B may be biased to the upper position. In other alternate embodiments, only one or neither lever  44 A,  44 B is biased and therefore has no default position. 
     In the illustrated embodiment in which each lever  44 A,  44 B is biased to the lower, default position, each lever  44 A,  44 B is manually actuated upwardly from the lower position to incrementally rotate the toothed gear(s) or wheel(s) of a respective ratcheting web retractor in the web take-up direction and thereby incrementally tightening a respective one of the lap web(s) and thigh web(s) about the occupant  100 . In the illustrated embodiment, each lever  44 A,  44 B returns under bias to its lower position, where the ratcheting process may be repeated. In embodiments in which the levers  44 A,  44 B are not biased to the lower position, each lever  44 A,  44 B must be manually returned to the lower position before repeating the ratcheting process. 
     Referring not to  FIGS. 8 and 9 , an example embodiment of the ratcheting web adjustment apparatus  140  is shown. In the illustrated embodiment, the lap webs  72 A,  72 B are provided in the form of a single length of web coupled to a dual-web retractor  142 A mounted in the seat module base  34 , and the thigh webs  74 A,  74 B are likewise provided in the form of a single length of web coupled to a dual-web retractor  142 B mounted in the seat base. Examples of such dual-web retractors  142 A,  142 B are illustrated and described in co-pending U.S. Patent Application Ser. No. 62/855,048, filed May 31, 2019, as assigned to the assignee of this disclosure, and the disclosure of which has been expressly incorporated herein by reference in its entirety. The retractors  142 A,  142 B include frames  144 A,  144 B to which a spool  146 A,  146 B is operatively mounted and coupled to a conventional power spring or main spring  148 A,  148 B configured to bias the spool  146 A,  146 B in the web take up direction. Each retractor  142 A,  142 B also includes a ratcheting apparatus  145 A,  145 B coupled thereto for selectively locking/releasing the retractor  142 A,  142 B and for incrementally shortening the respective web by ratcheting as described above. The release lever  42  is operatively coupled to the ratcheting apparatus  145 A via a conventional cable C 1 , and the ratcheting lever  44 B is operatively coupled to the ratcheting apparatus  145 A via another conventional cable C 2 . The release lever  42  is operatively coupled to the ratcheting apparatus  145 B via another conventional cable C 3 , and the ratcheting lever  44 A is operatively coupled to the ratcheting apparatus  145 B via another conventional cable C 4 . 
     Referring now to  FIG. 9 , some of the details of one of the web retractor  142 A are shown. In the illustrated embodiment, the spool  146 A is positioned and mounted between opposing side walls  144 A 1  and  144 A 2  of the frame  144 A, and the cables C 2  and C 3  are operatively coupled to another frame wall  144 A 3  coupled to the side wall  144 A 2 . The ratcheting apparatus  145 A illustratively includes a spool extension  146 A′ couple to and rotating with the spool  146 A, and a toothed wheel W rotatably mounted to the spool extension  146 A′. A release pawl  150 A defines a tooth  152 A which normally engages the toothed wheel W when the release lever  42  is in its default position so as to lock the spool  146 A from rotating in the web pay out direction. When the release lever  42  is actuated, the cable C 1  draws the tooth  152 A of the pawl  150 A away from the wheel W so as to allow the spool  146 A to rotate in the web take up and pay out directions. A conventional ratcheting member  156 A is operatively coupled to the spool extension  146 A′ and includes a conventional rotational component  156 A that is rotationally actuatable via the cable C 2  to incrementally ratchet the spool  146 A in the web take up direction as described above. 
     Referring now to  FIGS. 10-11C , an embodiment of another restraint system  160  is shown for securing the vehicle seat  10  to a frame member  16 B of the motor vehicle to prevent, at least under certain conditions, sliding or pivoting movement of the vehicle seat  10  but to allow such movement under static or normal operating conditions. Referring to  FIG. 10 , a portion of the restraint system  160  is shown which includes a conventional buckle member  162  releasably engaging the tongue member  84  mounted to the vehicle seat  10  as described above. Referring to  FIG. 11A , the remainder of the restraint system  160  is shown which includes a conventional inertial locking retractor, e.g., a conventional ALR or ELR or other conventional inertial locking retractor  166 , mounted, i.e., affixed, to the frame component  16 B of the motor vehicle. One end of a web  164  is operatively attached to the retractor  166  and the other is attached to the buckle  162 . Under dynamic operating conditions which results in locking of the inertial locking retractor  166 , the vehicle seat  10  is prevented from pivoting forward or from sliding forward as described above. However, under static conditions or under other operating conditions in which the inertial locking retractor  166  is not locked, the vehicle seat  10  may be pivoted forwardly as illustrated by example in  FIG. 11B  or may be slidably adjusted to a more forward position as illustrated by example in  FIG. 11C . 
     In  FIG. 12 , a variant  260  of the restraint system is shown in which one end of a web  264  is attached to the buckle  162  and the opposite end is secured to a stationary structure secured to the frame component  16 B of the motor vehicle. In some embodiments, a manual web length adjuster  268  may be provided to allow for manual length adjustments of the web  264 . In the embodiment illustrated in  FIG. 12 , the vehicle seat  10  is prevented from pivoting forward or from sliding forward under all conditions, and to pivot the seat  10  forward or slide the seat  10  forward the buckle member  162  must be disengaged from the tongue member  84 . 
     Referring now to  FIGS. 13-15D , an embodiment of another restraint system  360  for a variant  10 ′ of vehicle seat  10  is shown which is configured and operable to selectively secure the seat back module  20  generally, and the interconnected frame components of the seat back module  20  in particular, to a frame  16 B 1 ,  16 B 2  or other structural component of the motor vehicle. In embodiments in which the vehicle seat  10 ′ is configured to pivot forwardly from its occupant support position as described above, and/or in which the vehicle seat  10 ′ is configured to be adjustably positionable fore and aft as also described above, the restraint system  360  selectively secures the vehicle seat  10 ′, in particular the frame of the vehicle seat  10 ′, to the frame component  16 B 1 ,  16 B 2  or other structural component of the motor vehicle, while also allowing for such pivoting and/or adjustable positioning of the vehicle seat  10 ′. By securing the interconnected frame components of the vehicle seat  10 ′ to the frame  16 B 1 ,  16 B 2  or other structural component of the motor vehicle, the restraint system  360  advantageously allows for the mounting of the shoulder web retractor  64  to the interconnected frame components of the vehicle seat  10 ′ which, through the restraint system  360 , secures the web retractor  64  to the frame  16 B 1 ,  16 B 2  or other structure of the motor vehicle. 
     In the illustrated embodiment, the restraint system  360  includes a base bracket  362  mounted to the frame  16 B 1 ,  16 B 2  or other structure of the motor vehicle, an elongated bracket  364  having spaced apart side walls  364 A,  364 B of a lower end  364   1  pivotally mounted to the bracket  362  between spaced apart sidewalls  362 A,  362 B thereof via a pivot connector  366 , e.g., a bolt, pin or the like, and an upper end  364   2  extending away from the lower end, and a biasing member  368  coupled to and between the brackets  362 ,  364 . In the illustrated embodiment, the elongated bracket  364  is a planar bracket, although in alternate embodiments one or more portions of the bracket  364  may be non-linear or piecewise linear. A tab or plate section  362 C of the bracket  362  illustratively extends perpendicularly away from the plane formed by the bracket with a terminal end of the tab section  362 C facing the rear of the vehicle seat  10 ′. 
     An elongated coupling pin  370  is transversely mounted to the terminal end of the bracket  364  adjacent to the upper end thereof such that a longitudinal axis extending centrally through the coupling pin  370  is perpendicular to a longitudinal axis extending centrally through the bracket  364 . In the illustrated embodiment, the coupling pin  370  illustratively includes an elongated pin with guide wheels  370 A,  370 B mounted at each end thereof. The restraint system  360  further includes a conventional web retractor  372  mounted to the bracket  362  and/or to the frame  16 B 1 ,  16 B 2  of the motor vehicle. A length of web  374  is operatively coupled at one end to a rotatable spool of the web retractor  372  and at the opposite end to the coupling pin  370 , and the portion of the web  374  between the web retractor  372  and the coupling pin  370  rides on the upper surface of the tab section  362 C of the bracket  362 . 
     The biasing member  368 , e.g., a torsion spring, illustratively biases the bracket  364  away from the frame  16 B 1 ,  16 B 2  such that the plane formed by and along the bracket  364  forms an angle about the pivot connector  366  with the plane formed by the bracket  362 . Illustratively, the length of web  374  is selected to restrict pivoting of the bracket  364  about the pivot connector  366  to a maximum angle about the pivot connector  366 , corresponding to a maximum linear distance of the coupling pin  370  from the plane formed by the bracket  362  as illustrated in  FIG. 14 . The bracket  364  is pivotable about the pivot connector  366  between a maximum angle a minimum angle in which the rearwardly facing surface of the bracket  364  is adjacent to or spaced apart by a predefined distance from the forwardly facing surface of the bracket  362 . 
     The web retractor  372  illustratively includes a biasing member which biases the spool of the retractor  372  in the web take up direction. The biasing force of the biasing member  368  is illustratively greater than the biasing force of the biasing member of the web retractor  372  so that when the restraint system  360  is not being acted upon by the vehicle seat  10  the elongated bracket  364  pivots away from the bracket  362  and, in the process, draws the web  374  from the web retractor  372  until the maximum distance (or angle) allowed by the length of the web  374  is reached, at which point the restraint system  360  is in its fully extended position. If a force greater than, and generally opposite to, the biasing force of the biasing member  366  is applied to the bracket  364  and/or to the coupling pin  366 , the bracket  364  pivots rearwardly about the pivot connector  366  as the biased spool of the web retractor  372  rotates in the web take-up direction and takes up the web  374  therein until the minimum distance (or angle) is reached, at which point the restraint system  360  is in its fully retracted position. In the illustrated embodiment, the web retractor  372  is an emergency locking retractor (ELR) configured in a conventional manner to lock the spool and prevent the spool from rotating in the web payout direction upon detection of a rapid rate of payout of the web therefrom and/or upon detection of vehicle deceleration exceeding a vehicle deceleration threshold. 
     In the illustrated embodiment, the vehicle seat  10  is provided with structural features  180  configured to selectively engage, or to be selectively engaged by, the restraint system  360  in a manner which secures the interconnected frame components of the seat back module  20  to the restraint system  360  and thus to the frame  16 B 1 ,  16 B 2  of the motor vehicle. A rigid frame plate  48 C 1 ,  48 C 2  is illustratively affixed, i.e., secured, e.g., by welding or using a plurality of conventional fixation members, to each of the frame components  30 A,  30 B,  30 C. With respect to the seat back panel  60 A,  50 B, the frame plate  48 C 1 ,  48 C 2  illustratively extends upwardly from the space defined between the upper wings  50 E,  50 G and the lower wings  50 F,  50 H to the transverse frame component  30 C positioned near the tops of the upper wings  50 E,  50 G. In any case, a pair of elongated, laterally or transversely spaced apart engagement plates  182 A,  182 B are each secured at one end thereof to the frame plate  48 C 1  and, in some embodiments, to the transverse frame member  30 C. The engagement plates  182 A,  182 B each extend downwardly away from the frame member  30 C to terminal ends thereof, and a pair of matching spaces are defined between the rearwardly facing surface of the frame plate  48 C 1  and each respective one of the engagement plates  182 A,  182 B. The matching spaces are illustratively sized to receive therein respective portions of the coupling pin  370  therein. In the illustrated embodiment, the engagement plates  182 A,  182 B are illustratively at least partially arcuate in shape as then extend downwardly to the terminal ends thereof so as to guide the coupling pin  370  therein and therefrom as the vehicle seat  10 ′ is pivoted forwardly and rearwardly about the hinges  25 A,  25 B as described above. Illustratively, all frame components  30 A- 30 C, the coupling pin  370  and the brackets are made of a rigid, high-strength material such as steel. 
     The restraint system  360  just described is illustratively configured to automatically, i.e., without user intervention or manual actuation of the system  360 , adjust to accommodate any fore or aft position of the vehicle seat  10 ′ relative to the bracket  362  (i.e., relative to the frame  16 B 1 ,  16 B 2  of the motor vehicle) while remaining coupled to the vehicle seat  10 ′ at all times, and at any fore or aft position of the vehicle seat  10 ′ to also disengage from the vehicle seat  10 ′ when being pivoted forwardly from the occupant support position and reengage the vehicle seat  10 ′ when being pivoted from any forwardly pivoted position back to the occupant support position. 
     Starting with  FIG. 15C , the vehicle seat  10 ′ is shown in its occupant support position with the coupling pin  370  of the restraint system  360  received between the engagement plates  182 A,  182 B and the frame plate  48 C 1 ,  48 C 2  of the vehicle seat  10 ′, thereby securing the vehicle seat  10 ′ generally, and the frame components of the seat back module  20  in particular, to the frame  16 B 1 ,  16 B 2  of the motor vehicle via the restraint system  360 . Moving to  FIG. 15A , the vehicle seat  10 ′ is pivoted forwardly from the occupant support position of  FIG. 15C . The bracket  364  pivots toward the vehicle seat  10 ′ about the pivot connector  366  in order to maintain contact between the coupling pin  370  and the frame plate  48 C 1 ,  48 C 2 , e.g., between the coupling pin rollers  370 A,  370 B and the frame plate  48 C 1 , to ensure that the engagement plates  182 A,  182 B clear the coupling pin  370  as the seat  10 ′ pivots forwardly. In  FIG. 15A , the vehicle seat  10 ′ is shown pivoted to a forward position in which it is clear from the restraint system  360 . In this position, the restraint system  360  is in its fully extended position. 
     Moving now to  FIG. 15B , the vehicle seat  10 ′ has been pivoted from a forward position clear of the restraint system  360  back toward the restraint system  360 . In  FIG. 15B , the coupling pin  370  has just made contact with the frame plate  48 C 1  below the terminal ends of the engagement plates  182 A,  182 B. The coupling pin guide wheels or rollers  370 A,  370 B ride along the frame plate  48 C 1  as pivoting of the vehicle seat  10 ′ continues rearwardly, thereby guiding the elongated pin  2370  into the spaces defined between the engagement plates  182 A,  182 B and the frame plate  48 C 1  as the rearward force of the frame plate  48 C 1  acting on the coupling pin  370  forces the bracket  364  to pivot toward the bracket  362  as the web  374  retracts within the web retractor  372 . 
     Moving again to  FIG. 15C , the vehicle seat  10 ′ has completed pivoting rearwardly and is in its occupant support position. In this position, the coupling pin  370  has traveled upwardly through the spaces between the engagement plates  182 A,  182 B and the frame plate  48 C 1  to secure the restraint system  360  to the vehicle seat  10 ′, and the bracket  364  has further pivoted toward the bracket  362  and the web  374  has further retracted within the web retractor  372 . 
     Operation of the restraint system  360  to automatically, i.e., without user intervention or manual actuation of the system  360 , adjust to accommodate any fore or aft position of the vehicle seat  10 ′ relative to the bracket  362  (i.e., relative to the frame  16 B 1 ,  16 B 2  of the motor vehicle) while remaining coupled to the vehicle seat  10 ′ at all times is depicted in steps. Starting with  FIG. 15C , the vehicle seat  10 ′ is shown in its occupant support position with the coupling pin  370  of the restraint system  360  received between the engagement plates  182 A,  182 B and the frame plate  48 C 1  of the vehicle seat  10 ′, thereby securing the vehicle seat  10 ′ generally, and the frame components of the seat back module  20  in particular, to the frame  16 B 1 ,  16 B 2  of the motor vehicle via the restraint system  360 . As illustrated in  FIG. 15C , the vehicle seat  10 ′ is in its maximum forward position. 
     In  FIG. 15D , the occupant has actuated the seat adjustment lever and has then applied a rearward force to the vehicle seat  10 ′ to adjust the position of the vehicle seat  10 ′ relative to the floor or floor frame members  16 A,  16 B. In  FIG. 15D , the vehicle seat  10 ′ has been moved to its maximum rearward position. It is evident that rearward movement of the vehicle seat  10  while in the occupant supporting position has forced the bracket  364  to pivot rearwardly so as to maintain the coupling pin  370  engaged between the engagement plates  182 A,  182 B as described above. As the vehicle seat  10 ′ has moved rearwardly, the web  374  has retracted within the web retractor  372  as also described above. Illustratively, the restraint system  360  is configured such that in the maximum rearward position of the vehicle seat  10 ′, the restraint system is at or near is fully retracted or compact configuration.
