RELATED APPLICATIONS This is a divisional of U.S. patent application Ser. No. 11/915,797, filed Sep. 22, 2008 now abandoned and published as U.S. Patent Application Publication No. 2009/0152848 on Jun. 18, 2009, which application claims the benefit of International Patent Application No. PCT/US2006/021507, filed Jun. 2, 2006 and published as International Patent Application Publication No. WO 2006/132990, which claims the benefit of U.S. Provisional Application No. 60/687,035, filed Jun. 3, 2005, and U.S. Provisional Application No. 60/762,463, filed Jan. 26, 2006. The entire contents of each of these applications are hereby incorporated by reference.
FIELD OF THE INVENTION The present invention relates generally to protective devices as are often installed in motor vehicles, such as automobiles, and, more particularly, the invention is directed to an inflatable bolster for use in a vehicle.
BACKGROUND OF THE INVENTION Several types of device have been proposed for protecting vehicle occupants during a crash event. Such devices can be categorized as being either passive devices or active devices.
SUMMARY OF THE INVENTION In a first aspect, the invention is directed to an active bolster for a vehicle, wherein the bolster includes a hollow main body that is inflatable and is self-supporting in both an inflated and in an uninflated position.
BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described by way of example only with reference to the attached drawings, in which:
FIG. 1C is a sectional side view of the bolster in an uninflated position shown in FIG. 1A;
FIG. 21E is a perspective assembled view of the bolster shown in FIG. 21A shown in an inflated configuration;
DETAILED DESCRIPTION OF THE INVENTION Examples of inflatable bolsters include the structures illustrated in U.S. Pat. Nos. 6,032,978, 6,203,057, and 6,578,867, the entire contents of which are incorporated herein by reference.
Reference is made to FIGS. 1A, 1B, 1C and 1D, which illustrate an active bolster 10 in accordance with a first embodiment of the present invention. The active bolster 10 is positioned on a door 17 of a vehicle 15, and deploys to protect a vehicle occupant 13 (see FIG. 1C) during a crash event and in particular during a side impact incurred by the vehicle 15 (see FIG. 1A). The vehicle 15 may be any applicable vehicle, such as an automobile, an SUV (sport-utility vehicle), or a pick-up truck. The active bolster 10 can be configured to absorb energy to protect the upper torso, thorax, lower torso, head or combinations of these regions of the occupant 13 (FIG. 1C) during a crash event.
Referring to FIG. 1C, the bolster 10 includes a hollow main body 11 and an attachment means 21. The hollow main body 11 is inflatable and is self-supporting in both an inflated position (FIG. 1C) and in an uninflated position (FIG. 1D). The main body 11 has an outside wall 12, an inside wall 14 and a side wall 16 that connects the outside and inside walls 12 and 14. The outside wall 12 of the bolster 10 is the wall that faces towards the outside of the vehicle 15. In the embodiment shown in FIGS. 1A-1D, the outside wall 12 is captured by the attachment means 21.
The inside wall 14 is the wall that faces the interior of the vehicle 15. In the bolster's folded state, as shown in FIGS. 1A and 1C, the inside wall 14 may form part of the interior door panel 19 of the vehicle 15. In such a case, the inside wall 14 may be provided with a suitable finish, eg. in accordance with the design theme for the rest of the vehicle interior. Thus, the inside wall 14 may act as a first surface, ie. a surface that is directly exposed to view by a vehicle occupant 13.
The hollow main body 11 includes one or more pleats 18 thereon, which may be positioned around the sidewall 16, as shown in FIGS. 1C and 1D. The pleats 18 permit the expansion of the hollow main body 11 upon the introduction of a pressurized gas therein. The number, stiffness and position of the pleats 18 can be selected depending upon the selected direction of expansion of the bolster 10. The pleats 18 may be configured to control the amount and direction of expansion of the main body 11, so that the inside wall 14, and the overall body 11, may be positioned in a selected position relative to the vehicle occupant 13 to provide selected energy absorption for selected regions of the occupant's body.
The pleats 18 need not be positioned on the sidewall 16. For example, referring to FIGS. 2A and 2B, the pleats 18 may be provided on the inside wall 14. In the case where they are provided on the inside wall 14, it may be desirable for aesthetic reasons for the inside wall 14 to be covered by a suitable interior door panel segment 19 a to hide the pleats 18 from view by the vehicle occupants.
Referring to FIGS. 1C and 1D, the hollow body 11 includes an inlet 20 for receiving the inflation gas. The inflation gas may be provided by any suitable inflation device, such as an inflators used on air bag systems. If the bolster 10 includes multiple chambers therein, the inlet 20 may branch into several internal conduits, each of which connects the inlet to an internal chamber.
The bolster 10 is shown as being mounted on the door 17 below the armrest, shown at 26. During a crash event, pressurized air (or any suitable pressurized gas) is introduced into the hollow main body 11 from the inflator through the inlet 20. The pressurized gas causes the main body 11 to expand. In the embodiment shown in FIGS. 1A-1D, the main body 11 is configured to expand directly inwardly into the interior of the vehicle 15, towards the upper legs and hip region of the vehicle occupant 13 seated in the seat 28 adjacent the door 17. In this way, if the vehicle occupant 13 is accelerated by the crash event towards the door 17, he/she will encounter the bolster 10 earlier than he/she would have encountered the door 17, had the bolster 10 not been present. As a result, the occupant 13 will have reached a lower velocity when encountering the bolster 10 than he/she would have reached if he/she had been free to accelerate all the way to the door 17. Additionally, the bolster 10 provides the occupant 13 with a greater distance over which to decelerate. As a result of the lower velocity and the greater deceleration distance, the occupant 13 is less likely to sustain injury from the crash event. If the bolster 10 is provided with the vent means 22, the deceleration can be even better controlled, and the occupant 13 can be at even lower risk of sustaining injury from the crash event.
Reference is made to FIGS. 3A and 3B, in which the bolster 10 is shown as being mounted to the door 17 above the armrest 26. In this embodiment, the bolster 10 may be configured to extend inwardly into the interior of the vehicle 15 towards the occupant 13 and to present an inflated form that engages the upper torso, ie. the shoulder region, of the occupant 13, protecting the occupant from collision with both the door body, shown at 17 b and the lower region of the door window. The door window is shown at 17 a. In a crash event, the shoulder region of an occupant 13 may move farther towards the vehicle door 17 than the hip region of the occupant 13 does, since the shoulder region may be less securely held in place by a seat belt than the hip region. Thus, while protecting the hip region of the occupant 13 is valuable, it is also valuable to protect the shoulder region of the occupant 13 from colliding with the door 17. The bolster 10 shown in FIGS. 3A and 3B accomplish this. Additionally, by deploying to protect the shoulder region of the occupant 13, the bolster 10 in FIGS. 3A and 3B also protects the head of the occupant 13 by making it less likely that the head of the occupant will collide with the door 17.
Reference is made to FIGS. 4A and 4B, in which the bolster 10 is shown as being positioned aft of the armrest 26. In this position, the bolster 10 can cover a relatively large vertical stretch along the door body 17 b, without interference from the armrest 26. The bolster 10 could be configured to cover substantially the entire distance between the top of the door body 17 b, and the seat bottom portion, shown at 28 a. The bolster 10 can be configured to extend directly inwardly towards the occupant 13 and thereby protect a relatively large portion of the occupant's torso.
Reference is made to FIGS. 16A, 16B, 16C and 16D which show the bolster 10 including a first bolster portion 50 and a second bolster portion 52. The first and second bolster portions 50 and 52 are fluidically connected to an inflator, shown at 54, by fluid conduits 55 a and 55 b. Thus, in this embodiment, the bolster 10 includes two separate inflatable bolster portions 50 and 52, both of which are inflated by a single gas inflator 54. The outer wall 12 of the bolster portions 50 and 52 comprise peripheral portions 72, which extend relative to the door during inflation. This is advantageous in that the assembly may be less expensive than two separate bolster assemblies and two separate inflators. The bolster portions 50 and 52 are shown in their uninflated condition in FIGS. 16A and 16B, and are shown in their inflated condition in FIGS. 16C and 16D.
Additionally, it will be noted that dividing the bolster 10 into the first and second bolster portions 50 and 52 which are inflated by a common inflator 54, permits the bolster 10 to cover substantially all of the height of the door body (not shown in FIGS. 16A, 16B, 16C and 16D) above and below the armrest 26 (shown in FIGS. 16B and 16C), while avoiding pushing the armrest 26 itself into the interior of the vehicle. To facilitate this, the bolster 10 may be made relatively stiffer and uninflatable in the region 56 of the bolster 10 that is proximate the armrest 26. Stiffening the region 56 inhibits the bolster 10 from urging the armrest 26 into the vehicle interior during inflation of the bolster 10. Additionally, mounting plates 58 and 60 may be provided in the stiffened region 56, which contain mounting apertures 62, 64, 66 and 68, which are used to mount the bolster 10 to the vehicle's structure. Mounting the bolster 10 in the region 58 that is proximate the armrest 26 further assists in inhibiting the bolster 10 from urging the armrest 26 into the vehicle interior during bolster inflation. The mounting plates 58 and 60 may be made from any suitable material, such as a polymeric material that can be joined to the rest of the bolster 10 with suitable structural integrity.
Referring to FIG. 16E, there is illustrated in a front view an exposed interior door panel 19 showing side bolster 10 comprising the first 50 and second 52 bolster portions in accordance with a further embodiment of the invention. The bolster portions 50 and 52 are shown positioned in relation to the armrest 26 and a detachable interior panel portion 51 of the exposed interior door panel 19. The detachable interior panel portion 51 can be released from the door panel 19 by the inflation of the second bolster portion 52. For clarity, analogous elements between side bolster 10 of FIGS. 16A-16D, and side bolster 10 of FIGS. 16E-16I, are denoted by the same numerals. In FIGS. 16E and 16F, the bolster portions 50 and 52 are shown in their un-inflated condition.
Referring to FIG. 16F, the unexposed side of the interior door panel is shown in an interior view, and the side bolster 10 is shown with the first bolster portion 50 and the second bolster portion 52 positioned above and below the armrest 26 respectively. The inflator 54 is positioned close to the armrest 26, and the connection 71 between the fluid conduit 55 a and the first bolster portion 50 is shown. A relatively non-expansive attachment portion 61, including mounting plates 58 and 60, and mounting apertures 62, 64, 66 and 68 is also shown. The required strength and stiffness of the attachment portion 61 may be obtained by increasing the thickness of the wall surrounding the hollow interior of the attachment portion 61 appropriately to resist deformation due to the increased air pressure within the hollow interior that causes inflation of the bolster portions 50 and 52. The hollow interior of attachment portion 61 also houses the inflator module 54, which inflates both the first 50 and second 52 bolster portions. The attachment portion 61 is bordered by a peripheral portion 72.
The first 50 and second 52 bolster portions are fluidly connected to the inflator module 54 by fluid conduits 55 a and 55 b respectively. The junction 55 c between fluid conduits 55 a and 55 b comprises a �V� shaped hollow interior. The relative proportions and orientation of the �V� shaped junction 55 c are designed to direct an appropriate portion of the inflation gas into the first 50 and second 52 bolster portions to ensure proper inflation. The outer wall 12 of each bolster portion 50,52 contains pleats 18 to allow for the peripheral portion of the outer wall 12 of the bolster portions 50,52 to extend relative to the door during inflation.
Referring to FIG. 16G, the interior side of the door panel 19 a and the second bolster portion 52 are shown with the door panel metal support structure 70 in the foreground. The metal support structure 70 has a portion cut away to illustrate the location of the inflator 54 and second bolster portion 52 pleats 18 and the relative position of the mounting plate 60 and mounting apertures 66 and 68 with respect to the door panel metal support structure 70.
Referring to FIG. 16H, the first 50 and second 52 bolster portions are shown in a side view in relation to the vehicle door body 17 b, the vehicle door window 17 a, the interior door panel 19, the armrest 26, and the detachable interior panel portion 51. The first 50 and second 52 bolster portions are shown in an un-inflated condition. In this condition, expansible hollow interior 57 of each bolster portion 50, 52 is uninflated.
Referring to FIG. 16I, the side view of the side bolster 10 of FIG. 16H is repeated, with the side bolster shown in the inflated condition. As shown, both the first bolster portion 50 and the second bolster portion 52 can deploy into the vehicle interior around the armrest 26 to protect the shoulder and pelvic regions of the vehicle occupants 13 respectively. The detachable interior door panel 51 can be displaced, as shown in FIG. 16I by the inflation of the expansible hollow portion 57 of the second bolster portion 52. The expansion of the bolster portions 50, 52 involves movement of the inside wall 14 into the vehicle's interior and movement of the peripheral portion of the outside wall 12 away from the vehicle door body 17 b and window 17 a. The peripheral portion of the outside wall 12 may also extend along the dimension of the door body, so that, for example, bolster portion 50 may partly cover the window. The direction and extent of this displacement is affected by the design and number of pleats 18 contained in the outside wall 12 of the bolster.
The exposed surface of both the first bolster portion 50 and the second bolster portion 52 can be finished or covered suitably to act as a normal exposed surface or first surface in door-mounted embodiments, such as the embodiment shown in FIGS. 16E, 16F, 16G, 16H and 16I.
Reference is made to FIG. 17A, which shows a sectioned side view of a snap-in connection 71 a used between the fluid conduit 55 a and the outside wall 12 of a bolster portion 50 in an embodiment of the invention. During assembly, the opening of the fluid conduit 55 a is aligned with the appropriately sized opening in the outside wall 12 of the first bolster portion 50. External pressure is then applied to the fluid conduit 55 a forcing the conduit into the bolster portion 50. The angled shape of the fluid conduit tabs 69 allow for the conduit to be relatively easily inserted into the outside wall of the bolster portion 50, but create significant resistance preventing the conduit from subsequently being removed from the outside wall 12 of the bolster portion 50. Once installed, the fluid conduit 55 a creates fluid communication between the inflator 54 (not shown in FIG. 17A or 17B) and the expansible hollow interior 57 of the bolster portion 50. The connection 71 a between the fluid conduit 55 a and the outside wall 12 of the bolster portion 50 is surrounded by expansion pleats 18 which facilitate movement and inflation of the bolster portion 50. Referring to FIG. 17B, the embodiment of the snap-in connection 71 a is shown in a sectioned perspective view relative to the fluid conduit 55 a and the outside wall 12 of a bolster portion 50.
FIGS. 18A and 18B show an alternate means for attaching the fluid conduit 55 a to the outside wall 12 of the bolster portion 50 to create a fluid connection 71 b between the inflator 54 (not shown in FIGS. 18A and 18B) and the expansible hollow interior 57 of the bolster portion 50. Reference is made to FIG. 18A, which shows a sectioned side view of a ferrule and gear clamp connection 71 b used between the fluid conduit 55 a and the first bolster portion 50 in an embodiment of the invention. The ferrule and gear clamp connection 71 b is an alternate means of securing the fluid conduit 55 a to the bolster portion 50 to the means shown in FIGS. 17A and 17B. Referring to FIG. 18B, the embodiment of the ferrule and gear clamp connection 71 b is shown in a perspective view. This view shows the relative positions of the fluid conduit 55 a, the outside wall 12 of the first bolster portion 50, and the expansion pleats 18.
Reference is made to FIG. 19A which shows a means to fasten a particular embodiment of the bolster 10 to the door panel metal support structure 70 in accordance with an embodiment of the invention. In this embodiment, the outside wall 12 of the bolster 10 comprises integral bolster mounting tabs 74, which are of an appropriate thickness and height to provide the required tensile strength and other desired mechanical properties to secure the bolster 10 to the structure 70 both before and during inflation. The integral bolster mounting tabs are positioned within the attachment portion 61, between the pleats 18 on the outer wall 12 of the bolster 10 and the connection 71 between the bolster 10 and the fluid conduit 55 a. The connections between the bolster 10 and the door panel metal support structure 70 within the attachment portion 61 of the bolster outer wall 12 remain in place during inflation of the expansible chamber 57. Additional frangible fasteners (not shown) may be used to detachably attach any of the peripheral portions 72 of the outer wall 12 of the bolster, including the expansion pleats 18, to the door panel metal support structure 70 while the bolster is in its uninflated configuration. Fasteners within the peripheral portions 72 of the bolster outer wall 12 can be released by inflation of the expansible chamber 57 so as to not prevent the outer wall 12 from moving relative to the side of the vehicle during inflation.
The particular attachment means shown in FIG. 19A comprises fastening clips 75 that are placed over the integral bolster mount tabs 74. The fastening clips 75 are affixed to the integral bolster mounting tabs 74 by rivets 76. This design is advantageous in that the integral bolster mounting tabs 74 are formed during the initial molding of the bolster 10 and the fastening clips 75 can be manufactured separately and then easily affixed to the bolster 10 via the rivets 76 prior to the bolster 10 being installed in the vehicle. Upon affixing the required fastening clips 75 to the integral bolster mounting tabs 74, the bolster can be positioned relative to the door panel metal support structure 70 and aligned with the predetermined fastening locations 63 within said structure. With the fastening clips 75 properly aligned with the fastening locations 63, pressure can be applied to the bolster portion 50 forcing the fastening clips 75 into the fastening locations 63 and creating a snap-fit connection between the outer wall 12 of the bolster 10 and the door panel metal support structure 70. This connection means can be implemented at the appropriate number of fastening locations 63 as required to produce the desired strength of mechanical connection between the bolster 10 and the door panel metal support structure 70.
Reference is made to FIG. 19B, which shows another embodiment of a means to fasten the outer wall 12 of an expansible chamber 57 to the door panel metal support structure 70. In this embodiment, the outside wall 12 of the active support bolster 10 comprises insert apertures 59 appropriately sized to receive mounting stud inserts 77, which are of an appropriate thickness and size to provide the required tensile strength and other desired mechanical properties. The insert apertures 59 are positioned within the attachment portion 61, between the expansion pleats 18 on the outer wall 12 of the bolster 10 and the connection 71 between the expansible chamber 57 and the fluid conduit 55 a. Additional frangible fasteners (not shown) may be used to detachably attach any of the peripheral portions 72 of the outer wall 12 of the bolster, including the expansion pleats 18, to the door panel metal support structure 70 while the bolster is in its uninflated condition. Fasteners within the peripheral portions 72 of the bolster outer wall 12 can be released by inflation of the expansible chamber 57 so as to not prevent the outer wall 12 from moving relative to the side of the vehicle during inflation.
The particular attachment means embodied in FIG. 19B comprises mounting stud inserts 77 that are secured in the bolster 10 and inserted through the fastening locations 63 in the door panel metal support structure 70. Fastening nuts 78, with a diameter appropriately larger than that of the fastening location openings 63, are then threaded onto the studs and tightened until the desired level of mechanical compression is achieved. This connection means can be implemented at the appropriate number of fastening locations 63 as required to produce the desired strength of mechanical connection between the bolster 10 and the door panel metal support structure 70.
Reference is made to FIG. 19C, which shows yet another embodiment of a means to fasten an expansible chamber 57 to the door panel metal support structure 70. In this embodiment, the outside wall 12 of an expansible chamber 57 comprises insert apertures 59 appropriately sized to receive bolster tab inserts 79, which are of an appropriate thickness and size to provide the required tensile strength and other desired mechanical properties. The insert apertures 59 are positioned in the attachment portion 61, between the pleats 18 on the outer wall 12, of the expansible chamber 57 and the connection 71 between the bolster 10 and the fluid conduit 55 a. Additional frangible fasteners (not shown) may be used to detachably attach any of the peripheral portions 72 of the outer wall 12 of the bolster, including the expansion pleats 18, to the door panel metal support structure 70 while the bolster is in its uninflated condition. Fasteners within the peripheral portions 72 of the bolster outer wall 12 can be released by inflation of the expansible chamber 57 so as to not prevent the outer wall 12 from moving relative to the side of the vehicle during inflation.
The particular attachment means embodied in FIG. 19C comprises fastening clips 80 that are placed over the bolster tab inserts 79. The fastening clips 80 can be manufactured separately and then easily affixed to the bolster tab inserts 79 prior to the bolster portion 50 being installed in the vehicle. Upon affixing the required fastening clips 80 to the bolster tab inserts 79, the bolster can be positioned relative to the door panel metal support structure 70 and aligned with the predetermined fastening locations 63 within the structure. With the fastening clips 80 properly aligned with the fastening locations 63, pressure can be applied to the bolster 10 forcing the fastening clips 80 into the fastening locations 63 and creating a snap-fit connection between the bolster 10 and the door panel metal support structure 70. This connection means can be implemented at the appropriate number of fastening locations 63 as required to produce the desired strength of mechanical connection between the bolster 10 and the door panel metal support structure 70.
Reference is made to FIGS. 5A and 5B, in which the armrest 26 includes the bolster 10. In this embodiment, the main body 11 of the bolster 10 is the structural member of the armrest 26. The main body 11 may be finished in any suitable way to provide a suitable first surface for the armrest 26. For example, the main body 11 may be textured and may be made from a coloured polymer. Alternatively, the main body 11 may be covered by a layer of polymeric foam and a skin, such as a vinyl covering.
Reference is made to FIGS. 6A and 6B, in which the headrest, shown at 28 b includes the bolster 10. In this embodiment, the main body 11 of the bolster 10 is also the structural member of the headrest 28 b. Similarly to the armrest 26 in the embodiment shown in FIGS. 5A and 5B, the main body 11 may be finished in any suitable way to provide a suitable first surface for the headrest 28 b. For example, the main body 11 may be covered by a layer of polymeric foam and a skin, such as a vinyl covering. The advantages provided by a bolster 10 that replaces the structural member of the headrest 28 b are similar to those provided by the bolster 10, which is the structural member of the armrest 26 in the embodiment shown in FIGS. 5A and 5B.
When inflated, the bolster 10 shown in FIGS. 6A and 6B provide additional deceleration distance for the head of the occupant 13, relative to a standard passive headrest during certain types of collision. Additionally, the bolster 10, when inflated, may be configured to provide some control over lateral movement of the occupant's head, by providing a dished forward surface.
Referring to FIGS. 7A and 7B, a combination of two bolsters 10 are provided. A headrest bolster 10 a cooperates with a neck bolster 10 b to position the occupant's head and neck and absorb impact energy therefrom. The headrest bolster 10 a may be similar to the headrest bolster 10 shown in FIGS. 6A and 6B. The neck bolster 10 b is provided to occupy, in its inflated form, the generally concave space at the back of the occupant's neck when the occupant's head encounters the inflated headrest bolster 10 a. By cooperating together, the headrest and neck bolsters 10 a and 10 b lengthen the deceleration of the occupant's head and neck, thereby reducing the likelihood of injury to the occupant, and in particular reducing the likelihood of whiplash.
Reference is made to FIGS. 8A and 8B, which show two bolsters 10. When the vehicle undergoes certain types of crash event, the occupant 13 is urged forward, and may be urged in such a manner as to slide forward through the shoulder belt, shown at 30 a and through the hip belt, shown at 30 b, towards the foot well (not shown). This is colloquially known as �submarining�. In this embodiment, the two bolsters 10 cooperate together to assist in maintaining the occupant 13 in the seat 28 and inhibit submarining of the occupant 13.
The forward pelvic bolster 10 d is positioned at the forward edge of the seat bottom portion 28 a, and is configured, in its inflated position, to raise the body-supporting surface of the seat 28 and the knees of the occupant 13 and to cup the pelvic region of the occupant 13 at the junction of the seat bottom portion 28 a and the backrest 28 c. Thus, when the occupant 13 is belted in, the lumbar bolster 10 c and the forward pelvic bolster 10 d cooperate to �fold� the occupant about the pelvic region. This folding of the occupant 13 impedes the occupant from sliding down and forward through the shoulder and hip belts 30 a and 30 b towards the foot well (not shown) during a crash event.
Reference is made to FIGS. 9A and 9B, which show an outside pelvic bolster 10, which assists in decelerating the pelvic region of the occupant 13 during certain types of crash event. As with the bolsters 10 c and 10 d shown in FIGS. 8A and 8B, the main body 11 of the bolster 10 in FIGS. 9A and 9B, may be covered with a suitable layer of polymer foam and with a suitable skin, which may be separate from the skin on the rest of the seating surface of the backrest 28 c. It is optionally possible for the bolster 10 to extend upwards farther along the backrest 28 c, or to be positioned farther up along the backrest 28 c to control the deceleration of other regions on the occupant's torso in addition to, or instead of, controlling the deceleration of the pelvic region.
Reference is made to FIGS. 10A and 10B, which show the bolster 10 positioned on the rear face of the backrest 28 c. The bolster 10 deploys to protect the legs of the occupant (not shown) positioned in the seat (not shown) behind the seat 28.
Reference is made to FIGS. 11A and 11B, which show a bolster 10 mounted on the floor pan of the vehicle 15. The bolster 10 deploys to control the position of the feet of the occupant 13 during certain types of crash event. The bolster 10 supports the feet of the occupant 13 from underneath via a foot-supporting surface that is displaced by inflation of the bolster 10.
Referring to FIGS. 12A and 12B, the bolster 10 may be positioned in part in the floor pan of the vehicle and in part in the toe pan. The bolster 10 may include the carpet covering and/or the drain channels 31 that are optionally provided on the bolster 10 shown in FIGS. 11A and 11B.
Referring to FIGS. 13A, 13B and 13C, one or more bolster systems 34 may be positioned about one or more rollover protection bars 32 which may be provided on the vehicle. Each bolster system 34 surrounds the associated rollover protection bar 32 and slow the deceleration of a vehicle occupant 13 prior to the occupant 13 encountering the rollover protection bar 32 during certain types of crash event. Referring to FIG. 13C, each bolster system 34 may include first and second bolsters 10, which together cover a rollover protection bar 32 circumferentially. Each bolster 10 includes a hollow main body 11, which is shaped to have a radially inner surface 36 which contacts and engages rollover protection bar 32, and which has a radially outer surface 38, in which there are a plurality of pleats 18. The pleats 18 permit the bolster 10 to expand radially when inflated.
The bolsters 10 may be housed in a covering layer 40. The covering layer 40 holds the bolsters 10 together about the rollover protection bar 32. Additionally, the covering layer 40 hides the pleats 18 on the bolsters 10, if pleats 18 are present. The covering layer 40 may be a tubular piece that is open at its ends and that has a longitudinally extending opening 42. The bolsters 10 may be introduced into the covering layer 40 through the open ends or by stretching open the longitudinal opening 42. The covering layer 42 is fit over the rollover bar 32 by stretching open the opening 42. The covering layer 40 may include one or more connectors 44 to permit the opening 42 to be held closed.
Reference is made to FIGS. 14A and 14B, which show the bolster 10 positioned on the vehicle roof, shown at 46. The bolster 10 deploys to extend downwards to assist in controlling the deceleration of the occupant 13 towards the door window 17 a and in particular towards the junction between the door 17 and the roof 46. The main body 11 of the bolster 10 may be finished to as to directly act as the first surface, or may be covered by a suitable piece of material that acts as the first surface. Alternatively, the main body 11 may be hidden from view by the headliner.
It is optionally possible for the bolster 10 to extend farther downwards than is shown in FIG. 14B, so that it can protect the head of the occupant from hitting relatively lower regions on the door window 17 a. Reference is made to FIGS. 14A and 14B, which show the bolster 10 positioned on the vehicle's B-pillar, shown at 48. The bolster 10 and may be configured to extend forwardly, rearwardly and inwardly away from the B-pillar.
Referring to FIG. 20A, a headrest 28 b in accordance with a further embodiment of the invention is shown in a perspective view. The headrest 28 b comprises a bolster 10 mounted on a headrest mounting bracket 87. The bolster 10 comprises a rear wall 86, side walls 16, and relatively non-expansible front wall 85 and front inside walls 85 a enclosing an expansible hollow interior 57. The bolster 10 further comprises an inflator 54, which is attached to the headrest mounting bracket 87, and an inflation aperture 90 that is integral to the front wall 85 of the bolster 10. The inflator 54 is located outside of expansible hollow interior 57 of the bolster 10. The headrest mounting bracket 87 positions the bolster 10 in an appropriate location relative to the vehicle seat back 28 d (shown in FIG. 21A). The headrest mounting bracket 87 is rigidly fixed to the vehicle seat back 28 d by an appropriate, secure fastening means (not shown). The front wall 85 of the bolster 10 is relatively non-expansible and comprises an attachment portion 61 that is rigidly attached to the headrest mounting bracket 87 using an appropriate fastening means (not shown). The rigid attachment portion 61 connecting the relatively non-expansible front wall 85 and the headrest mounting bracket 87 is required to hold the bolster 10 in place during routine operation of the vehicle and to ensure that the bolster 10 remains in place during inflation.
Referring to FIG. 20B, the headrest 28 b as shown in FIG. 20A is shown in an exploded view. This figure also shows a portion of non-expansible padding material 88 designed to provide static support to the head of the vehicle occupant 13. The non-expansible padding 88 is rigidly attached to the headrest mounting bracket 87 by an appropriate attachment means (not shown) and is designed to fill the cavity bounded by the bolster 10 front 85 and front inside 85 a walls. An external headrest cover 89 is also shown in this figure. The external headrest cover 89 is installed on an assembled headrest 28 b and may be finished appropriately to act as a first surface. Referring to FIG. 20C, a headrest 28 b as shown in FIGS. 20A and 20B is shown with the headrest cover 89 in place and headrest mounting bracket 87 visible.
Referring to FIG. 20D, the headrest 28 b as shown in FIGS. 20A, 20B and 20C is shown in an inflated configuration. This figure shows the relative displacement of the rear 86 and side walls 16 of the bolster 10 due to the expansion of the pleats 18 (shown in FIG. 20A) and expansible hollow interior 57. This figure also shows the non-expansible padding material 88, front wall 85, and front inside walls 85 a remaining in place relative to the headrest mounting bracket 87 after inflation.
Referring to FIG. 21A, a seat back 28 d bolster 10 is shown in accordance with a further embodiment of the invention. A seat 28 is shown comprising a seat bottom portion 28 a, a headrest portion 28 b, and a seat back portion 28 d. The seat back portion 28 d further comprises an attachment portion 61 and a peripheral portion 72. The attachment portion 61 and peripheral portion 72 are designed to appropriately mount a bolster 10 which is deployed to protect vehicle passengers riding in the backseat of the vehicle. This figure also shows a bolster 10 to be affixed to the seat back 28 d. The bolster 10 further comprises a occupant side wall 86, that forms part of the boundary of an expansible hollow interior 57, and an inflator module 54 that is used to inflate the expansible hollow interior 57 of the bolster 10.
Referring to FIG. 21B, the bolster 10 as shown in FIG. 21A is shown comprising an occupant side wall 86, side walls 16, and a seat side wall 85 which serve to bound an expansible hollow interior 57. The seat side wall 85 of the bolster 10 further comprises an attachment portion 61 and a peripheral portion 72. The attachment portion 61 of the bolster 10 is rigidly attached to the seat back 28 d (as shown in FIG. 21A) by an appropriate fastening means (not shown). The attachment means is such that the portion of the seat side wall 85 of the bolster 10 within the attachment portion 61 of the bolster is held in place during normal operation and inflation of the bolster 10. Portions of the bolster seat side wall 85 contained within the attachment portion 61 of the bolster 10 cannot move relative to the seat back attachment portion (designated using reference numeral 61 in FIG. 21A). Peripheral portions 72 of the bolster seat side wall 85 may be attached to the seat back 28 d (not shown) by appropriate frangible fastening means (not shown) such that the bolster 10 is held in place during normal operation of the vehicle but also such that the attachment means is released by the inflation of the expansible hollow interior of the bolster 10 allowing the seat side wall 85 to move away from the seat back 28 d and toward the back of the vehicle. The bolster seat side wall 85 further comprises expansion pleats 18 that allow for the inflation of the expansive hollow interior 57 of the bolster 10 and can also be designed appropriately to control the extent and direction of expansion. The bolster 10 is shown in an un-inflated configuration.
Referring to FIG. 21C, a sectioned view of the bolster 10 shown in FIG. 21B shows the expansion pleats 18 and peripheral portion 72 of the seat side wall 85 of the bolster 10. This figure also shows a sectioned view of the occupant side wall 86 and expansible hollow interior 57 of the bolster 10 in its un-inflated configuration.
Referring to FIG. 21D, a perspective view of a seat 28 and seat back 28 d shows the relative position of the bolster 10 shown in FIGS. 21A and 21B as attached to the seat back 28 d in an un-inflated configuration. The occupant side wall 86 of the expansible hollow interior 57 of the bolster 10 may be suitably covered or finished to serve as a first surface. During inflation of the expansible hollow interior 57, the occupant side wall 86 of the bolster 10 will move away from the seat back 28 d and toward the back of the vehicle.
Referring to FIG. 21E, a perspective view of a seat 28 and seat back 28 d shows the relative position of the bolster 10 shown in FIGS. 21A, 21B, and 21D as attached to the seat back 28 d in an inflated configuration. This figure shows the relative displacement away from seat back 28 d of the occupant side wall 86 and peripheral portions 72 of the seat side wall 85 of the bolster 10 during the inflation of the expansible hollow interior 57. The expansion pleats 18 are shown in their extended positions. The attachments between the seat side wall 85 and the seat back 28 d contained within the attachment portion 61 remain intact during expansion, and this portion of the seat side wall 85 does not extend away from the seat back 28 d. Several of the bolster embodiments shown in the Figures are made oversized so that they protect a relatively wide range of sizes of vehicle occupant and to protect occupants over a relatively wide range of seat adjustment positions in the vehicle. In other words, the bolsters 10 may be sized to protect an occupant whether his/her seat is adjustment to its rearmost available position or its forwardmost position.
