Title: Sport helmet comprising an occipital inner pad mounted to a movable rear support

Description:
FIELD OF THE INVENTION 
     The present invention relates to a sport helmet comprising an occipital inner pad mounted to a rear support that is movable when the wearer puts on the helmet for improving the fit of the sport helmet on the wearer&#39;s head. 
     BACKGROUND OF THE INVENTION 
     U.S. Publication 2012/0054947 entitled Helmet comprising an Occipital Adjustment Mechanism and published on Mar. 8, 2012 relates to a hockey or lacrosse helmet comprising a back inner pad for facing the back, left and right side regions of the wearer&#39;s head, an occipital inner pad located below the back inner pad for facing the occipital region of the wearer&#39;s head, a central member extending along the longitudinal axis of the helmet and comprising an upper part hingedly mounted with respect to the helmet shell and a lower part mounted to the occipital inner pad, a single wedging member located between the helmet shell and the central member an a single actuator connected to the single wedging member. The single actuator and wedging member are movable along the longitudinal axis of the helmet from a first position to a second position wherein, in use, in the first position, the occipital inner pad applies a first pressure upon the occipital region of the wearer&#39;s head, and in the second position, the occipital inner pad applies a second pressure upon the occipital region of the wearer&#39;s head, the second pressure being greater than the first pressure. 
     While the use of a single actuator and wedging member eliminates the use of two actuators and/or wedging members and allows the wearer to adjust the fit in the occipital region of the wearer&#39;s head in an easy and convenient way, there is still a need in the industry for a sport helmet which further reduces both the manufacturing cost and number of components, simplifies the design of the helmet and provide a proper helmet fit on the wearer&#39;s head.

     In the drawings, embodiments of the invention are illustrated by way of examples. It is to be expressly understood that the description and drawings are only for the purpose of illustration and are an aid for understanding. They are not intended to be a definition of the limits of the invention. 
     DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION 
     To facilitate the description, any reference numeral designating an element in one figure will designate the same element if used in any other figures. In describing the embodiments, specific terminology is resorted to for the sake of clarity but the invention is not intended to be limited to the specific terms so selected, and it is understood that each specific term comprises all equivalents. 
     Unless otherwise indicated, the drawings are intended to be read together with the specification, and are to be considered a portion of the entire written description of this invention. As used in the following description, the terms “horizontal”, “vertical”, “left”, “right”, “up”, “down” and the like, as well as adjectival and adverbial derivatives thereof (e.g., “horizontally”, “rightwardly”, “upwardly”, “radially”, etc.), simply refer to the orientation of the illustrated structure. Similarly, the terms “inwardly,” “outwardly” and “radially” generally refer to the orientation of a surface relative to its axis of elongation, or axis of rotation, as appropriate. 
       FIGS. 1 and 2  illustrate a head of a wearer. The head comprises a crown region CR, left and right side regions LS, RS, a back region BR and an occipital region OR. The crown region CR has a front part that substantially corresponds to the forehead and a top part that substantially corresponds to the front top part of the wearer&#39;s head. In fact, the crown region CR generally corresponds to the frontal bone region of the wearer&#39;s head. The left and right side regions LS, RS are approximately located above the ears of the player. The occipital region OR substantially corresponds to the region around and under the external occipital protuberance of the wearer&#39;s head. 
       FIGS. 3 to 5  show an example of a helmet  10  for protecting the head of a wearer in accordance with an embodiment of the invention. In this embodiment, the helmet  10  is a sport helmet for protecting the head of the wearer who is a sport player. More particularly, in this embodiment, the sport helmet  10  is a hockey or lacrosse helmet for protecting the head of the wearer who is a hockey or lacrosse player. It is noted, however, that the invention is not limited to any particular type of sport helmet. For instance, a sport helmet constructed using principles described herein in respect of the sport helmet  10  may be used for protecting the head of a player of another type of contact sport (sometimes referred to as “full-contact sport” or “collision sport”) in which there are significant impact forces on the player due to player-to-player and/or player-to-object contact. For example, in one embodiment, a sport helmet constructed using principles described herein in respect of the sport helmet  10  may be a football helmet for protecting the head of a football player. Furthermore, a sport helmet constructed using principles described herein in respect of the sport helmet  10  may be for protecting the head of a wearer involved in a sport other than a contact sport (e.g., bicycling, motorcycle, skiing, snowboarding, horseback riding or another equestrian activity, etc.). 
     The sport helmet  10  defines a cavity for receiving the wearer&#39;s head to protect the head when the sport helmet  10  is impacted (e.g., when the sport helmet  10  hits a board, ice or other playing surface or is struck by a puck, ball, a lacrosse or hockey stick, or when the player is receiving a hit (e.g., body check) by another player and the head of the player is hit directly or indirectly). 
     The sport helmet  10  has a front-back axis, a left-right axis, and a vertical axis VA which are respectively generally parallel to a dorsoventral axis, a dextrosinistral axis, and a cephalocaudal axis of the wearer when the sport helmet  10  is worn and which respectively define a front-back direction, a left-right direction, and a vertical direction of the sport helmet  10 . Since they are generally oriented longitudinally and transversally of the sport helmet  10 , the front-back axis and the left-right axis can also be referred to as a longitudinal axis LA and a transversal axis TA, respectively, while the front-back direction and the left-right direction can also be referred to a longitudinal direction and a transversal direction. The longitudinal axis LA may be seen as an axis that resides within an imaginary longitudinal plan that bisects the sport helmet in two generally identical halves. 
     The helmet  10  has an outer shell  12 , inner padding  14 , a rear support  160  and an occipital inner pad  18  mounted to the rear support  160 . The outer shell  12  may comprises a front shell portion  20  and a rear shell portion  22 , the front shell portion  20  comprising outer and inner surfaces  24 ,  26  and the rear shell portion  22  comprising outer and inner surfaces  28 ,  30 . 
     The front and rear shell portions  20 ,  22  may be made of a relatively rigid material, such as polyethylene, NYLON, polycarbonate materials, thermoplastics, or thermosetting resins or any other suitable material. 
     The sport helmet  10  also comprises ear loops  34  and a chinstrap  36  for securing the sport helmet  10  to the wearer&#39;s head. The sport helmet  10  may further comprise ear protectors  38  for protecting the left and right ears of the wearer. 
     The front outer shell portion  20  comprises a top portion  20 T for facing at least part of the top region TR of the wearer&#39;s head, a front portion  20 F for facing at least part of the front region FR of the wearer&#39;s head, and left and right side portions  20 L,  20 R extending rearwardly from the front portion  20 F for facing at least part of the left and right side regions LS, RS of the wearer&#39;s head. 
     The rear outer shell portion  22  comprises a top portion  22 T for facing at least part of the crown region CR and top region TR of the wearer&#39;s head, a back portion  22 B for facing at least part of the back region BR and top region TR of the wearer&#39;s head, an occipital portion  22 O for facing at least part of the occipital region OR of the wearer&#39;s head, and left and right side portions  22 L,  22 R extending forwardly from the back portion  22 B for facing at least part of the left and right side regions (LS, RS respectively) of the wearer&#39;s head. 
     The front and rear shell portions  20 ,  22  overlay the inner padding  14 , which may have a front inner pad  14 F for covering at least part of the crown region CR and top region TR of the wearer&#39;s head, a top inner pad  14 T for covering at least part of the top region TR of the wearer&#39;s head and a back inner pad  14 B for covering at least part of the back region BR and top region TR of the wearer&#39;s head. Each of the inner pads  14 F,  14 T,  14 B comprises shock-absorbing material to absorb impact energy when the sports helmet  10  is impacted. For example, in this embodiment, each of the inner pads  14 F,  14 T,  14 B comprises polymeric cellular material. For instance, the polymeric cellular material may comprise polymeric foam such as expanded polypropylene (EPP) foam, expanded polyethylene (EPE) foam, or any other suitable polymeric foam material and/or may comprise expanded polymeric microspheres (e.g., Expancel™ microspheres commercialized by Akzo Nobel). Any other material with suitable impact energy absorption may be used for the inner padding  14  in other embodiments. 
     The front inner pad  14 F has a three-dimensional external configuration that matches the three-dimensional internal configuration of the front shell portion  20  and is mounted to the front shell portion  20  by any suitable affixing means, such as glue, stitches, tacks, staples or rivets. Similarly, the back inner pad  14 B has a three-dimensional external configuration that matches the three-dimensional internal configuration of the rear shell portion  22  and is mounted to the rear shell portion  22  by any suitable means, such as glue, stitches, tacks, staples or rivets. 
     The helmet  10  may also comprise left and right side comfort pads  40 L,  42 L,  40 R,  42 R affixed on the inner surface of the front inner pad  14 F. The comfort pads  40 L,  40 R,  42 L,  42 R comprise any suitable soft material providing comfort to the wearer. For example, in some embodiments, the comfort pad members  40 L,  40 R,  42 L,  42 R may comprise polymeric foam such as polyvinyl chloride (PVC) foam or polyurethane foam (e.g., PORON XRD foam commercialized by Rogers Corporation). 
     The inner padding  14  may be implemented in various other ways in other embodiments. For example, in other embodiments, the inner padding  14  may comprise any number of pads (e.g.: two pads such as a first pad that faces at least part of the front region FR, top region TR, and left and right side regions LS, RS of the wearer&#39;s head and another second pad that faces at least part of the back region BR, top region TR, and left and right side regions LS, RS of the wearer&#39;s head; a single pad that faces at least part of the front region FR, top region TR, left and right side regions LS, RS, and back region BR of the wearer&#39;s head; etc.). 
     The occipital inner pad  18  is located below the back inner pad  14 B for facing the occipital region OR of the wearer head. The occipital inner pad  18  may be made of expanded polypropylene (EPP) or expanded polyethylene (EPE) or polypropylene foam or polyethylene foam having two different densities. Other materials can also be used for the occipital inner pad  18  without departing from the spirit of the invention. 
     The sport helmet  10  may be adjustable to adjust and improve its fit on the wearer&#39;s head. To this end, the sport helmet  10  comprises an adjustment mechanism  44  for adjusting a fit of the sport helmet  10  on the wearer&#39;s head  11 . The adjustment mechanism  44  allows the fit of the sport helmet  10  to be adjusted by being operable by the wearer to vary the internal volume of the cavity of the sport helmet  10 . This can be done by adjusting one or more of the internal dimensions of the cavity of the sport helmet  10 , such as the longitudinal dimension of the cavity in the front-back direction of the sport helmet  10  and/or the transversal dimension of the cavity in the left-right direction of the sport helmet  10 . 
     More particularly, in this embodiment, the outer shell  12  and the inner padding  14  are adjustable to adjust the fit of the sport helmet  10  on the wearer&#39;s head. To that end, in this case, the front shell portion  20  is a separate front shell member and the rear shell portion  22  is a rear shell member, these front and rear shell members being movable relative to one another to adjust the fit of the sport helmet  10  on the wearer&#39;s head. The adjustment mechanism  44  is connected between the front shell member and the rear shell member to enable adjustment of the fit of the sport helmet  10  by moving the shell members relative to one another. In this example, relative movement of the outer shell members for adjustment purposes is in the front-back direction of the sport helmet  10  such that the front-back internal dimension of the cavity of the sport helmet  10  is adjusted. 
     As is best shown in  FIGS. 4 and 5 , the adjustment mechanism  44  may comprise an actuator  46  mounted to the rear shell member and that can be moved (in this case pivoted) by the wearer between a locked position, in which the actuator  46  engages a part of the front shell member and thereby locks the shell members relative to one another, and a released position, in which the actuator  46  is disengaged from the part of the front shell member and thereby permits the shell members to move relative to one another so as to adjust the size of the helmet  10 . 
     In use, a wearer who puts on the helmet  10  and realizes that it is too large or too small does not need to remove the helmet  10  to adjust it. Instead, the wearer just simply pivots outwardly (opens) the actuator  46 , expands or contracts the size of the helmet  10  by displacing the front and rear shell members in relation to each other in the appropriate direction, and then pivots inwardly (closes) the actuator  46  when the internal size of the helmet is adequate. 
     The actuator  46  may comprise first and second pairs of teeth  48 ,  50  extending generally transversely relative to the longitudinal axis LA in the locked position. The actuator  46  can be moved (in this case pivoted) by the wearer between a locked position, in which the first and second pairs of teeth  48 ,  50  engage in first and second plurality of pairs of apertures provided on the front shell member and thereby locks the shell members relative to one another, and a released position, in which the first and second pairs of teeth  48 ,  50  are disengaged from the first and second pairs of apertures of the front shell member and thereby permits the shell members to move relative to one another so as to adjust the size of the sport helmet  10 . It is understood that the actuator may comprise only one tooth, or only one pair of teeth instead of the first and second pairs of teeth  48 ,  50 . The adjustment mechanism  44  may also comprise a base member  52  having first and second posts  54 ,  56  to which the actuator  46  is pivotably mounted and the base member  52  may comprise first and second apertures for receiving the pair of first and second teeth  48 ,  50 . Again, it is understood that the base member  52  may comprise only one aperture if the actuator  46  has only one tooth or only one pair of teeth. The base member  52  may be mounted between the top pad  14 T and the front shell member and the first and second posts  54 ,  56  may extend in left and right apertures provided on the rear shell member. The adjustment mechanism  44  may be implemented in various other ways in other embodiments. 
     The outer shell  12  may comprise a plurality of ventilation holes  58  for allowing air to circulate around the wearer&#39;s head. In this case, each of the front and rear shell portions  20 ,  22  includes a plurality of ventilation apertures  58  that allow air to circulate around the head of the player to improve the player&#39;s comfort level 
     The outer shell  12  may be implemented in various other ways in other embodiments. For example, the outer shell may comprise separate front and rear shell members that are connected to one another in any suitable way, but are not adjustable relative to the other. 
     In another possible variant, the front and rear shell portions may be integrally formed together such that the outer shell  12  is a single one-piece shell. In such embodiments, the adjustment mechanism may comprise an internal adjustment device located within the sport helmet  10  and having a head-facing surface movable relative to the wearer&#39;s head in order to adjust the fit of the sport helmet  10 . For instance, in some cases the internal adjustment device may comprise an internal pad member movable relative to the wearer&#39;s head or an inflatable member which can be inflated so that its surface can be moved closer to or further from the wearer&#39;s head to adjust the fit. 
     As is best shown in  FIGS. 6A to 6D, 7 to 9, 10A and 10B , the rear support  160  has an upper part or member  162  hingedly mounted to the back inner pad  14 B, the top inner pad  14 T or the rear shell portion  22 . The upper member  162  extends along the longitudinal axis LA and has a top end portion  164  hingedly mounted with respect to the back and top inner pads  14 B,  14 T and a bottom end portion  166 . The top end portion  164  has an inner projection or peg  164 P and the top inner pad  14 T has a hole or aperture  14 TA for receiving the peg  164 P such that the upper member  162  is hingedly mounted to the top inner pad  14 T. It is understood that the top end portion  164  can rather be hingedly mounted with respect to the rear shell portion  22 . 
     The rear support  160  also comprises a transversal member  168  extending transversally on each side from the bottom end portion  166  up to left and right end portions  170 ,  172  and left and right members  174 ,  176  extending downwardly from the left and right end portions  170 ,  172  up to left and right bottom end portions  178 ,  180  that are joined with a lower part or lower member  182  that extends transversally with respect to the longitudinal axis LA front a left end portion  182 L to a right end portion  182 R. 
     The left and right end portions  170 ,  172  has left and right inner projections or pegs  170 P,  172 P and the back inner pad  14 B has left and right holes or apertures  14 BA for receiving the left and right pegs  170 P,  172 P. 
     The back and top inner pads  14 B,  14 T may each comprise channeled portions  14 C for at least partially receiving the upper, transversal, left and right members  162 ,  168 ,  174 ,  176 . 
     The lower member  182  defines an inner portion  184  to which the occipital inner pad  18  is mounted. For example, the inner portion  184  may comprise a transversal base wall  186  provided on the lower member  182 , a central wall  188  projecting upwardly from the base wall  186  and left and right walls  190 ,  192  extending inwardly from the left and right members  174 ,  176  and the occipital inner pad  18  may comprise a transversal base channel or depression  18 BD for receiving the base wall  186 , a central depression  18 CD for receiving the central wall  188  and left and right depressions  18 LD,  18 RD for receiving the left and right walls  190 ,  192 . The occipital inner pad  18  can thus be snugly mounted to the inner portion  184  of the lower member  182  through the engaging connections of the base, central, left and right walls  186 ,  188 ,  190 ,  192  in the base, central, left and right depressions  18 BD,  18 CD,  18 LD,  18 RD. Glue or other affixing means can also be used in order to further secure such engaging connections. Alternatively, the inner portion of the lower member may simply define a single wall for receiving the occipital inner pad that can be affixed to the lower member via affixing means such as glue, stitches, rivets, tacks, staples, etc. In another example, the lower member may be attached to the occipital inner pad by virtue of being integral, and therefore continuous, with the occipital inner pad. 
     The sport helmet also comprises a biasing member between the rear shell portion  22  and the rear support, the biasing member having a portion that abuts the inner surface  30  of the real shell portion  22  such that the rear support and occipital inner pad  18  are movable between a first position wherein the rear support is biased to extend inwardly from the inner surface  30  of the rear shell portion  22 , and a second position when the wearer puts on the sport helmet wherein the rear support and occipital inner pad  18  are deflected towards the inner surface  30  of the rear shell portion  22  while the rear support and occipital inner pad  18  maintain pressure on the occipital region OR of the wearer&#39;s head. 
     For instance, the biasing member may be provided on the rear support  160  that may comprise left and right end biasing members  194 ,  196  and left and right middle biasing members  198 ,  200 , each of the biasing members  194 ,  196 ,  198 ,  200  extending rearwardly towards the inner surface  30  of the real shell portion  22 , along an acute angle 0 with respect to a longitudinal axis L parallel to the longitudinal axis LA, and having a distal end portion abutting the inner surface  30  of the real shell portion  22  such that the rear support  160  and occipital inner pad  18  are movable between a first position wherein the rear support  160  is biased to extend inwardly from the inner surface  30  of the rear shell portion  22  forming a gap (see  FIGS. 10A, 11  A), and a second position when the wearer puts on the sport helmet, wherein the rear support  160  and occipital inner pad  18  are deflected towards the inner surface  30  of the rear shell portion  22 , reducing the gap, while the rear support  160  and occipital inner pad  18  maintain pressure on the occipital region OR of the wearer&#39;s head (see  FIGS. 10B, 11B ). As best shown in  FIG. 10A , in the first position, the lower member  182  of the rear support  160  may extend inwardly from the inner surface  30  of the rear shell portion  22  between a distance D measured along the longitudinal axis LA of about 5 mm to about 20 mm. 
     In one example, the biasing members  194 ,  196 ,  198 ,  200  may extend along an acute angle Θ that is between 60° and 80°. It is understood that the left and right end biasing members  194 ,  196  may extend along an acute angle Θ that is different from the acute angle Θ of the left and right middle biasing members  198 ,  200 . For example, in the first position, the left and right end biasing members  194 ,  196  may extend along an acute angle Θ that is between 65° and 75° and the left and right middle biasing members  198 ,  200  may extend along an acute angle Θ that is between 60° and 70°. 
     It is understood that the left and right end biasing members  194 ,  196  may each have a length that is different from the length of the left and right middle biasing members  198 ,  200 . For example, the left and right end biasing members  194 ,  196  may have a length that is between 25 mm and 35 mm and the left and right middle biasing members  198 ,  200  may have a length that is between 20 mm and 30 mm. 
     The biasing members  194 ,  196 ,  198 ,  200  are made of a resilient material, such as nylon, polyacetal (DELRIN™), polycarbonate or spring steel, any combination of these materials, or any other suitable material that has the ability to return to its original shape when pressure is no longer applied to it, such that the rear support  160  is biased to extend inwardly from the inner surface  30  of the rear shell portion  22  when the sport helmet is not worn by the wearer (first position shown in  FIGS. 10A, 11A ). It is understood that the rear support  160 , including the biasing members  194 ,  196 ,  198 ,  200  may be entirely made of the same resilient material or the biasing members  194 ,  196 ,  198 ,  200  may be made of a resilient material while the remainder of the rear support may be made of a material having a different resiliency. 
       FIG. 12  shows a rear support  260  according to a second embodiment. While the rear support  260  has left and right end biasing members  262 ,  264  and left and right middle biasing members  266 ,  268 , the rear support  260  also comprises a central biasing member  270 , each of the biasing members  262 ,  264 ,  266 ,  268 ,  270  extending rearwardly towards the inner surface  30  of the real shell portion  22 , along an acute angle with respect to a longitudinal axis parallel to the longitudinal axis LA and having a distal end portion abutting the inner surface  30  of the real shell portion  22 , such that the rear support  260  and occipital inner pad  18  are movable between a first position wherein the rear support  260  is biased to extend inwardly from the inner surface  30  of the rear shell portion  22 , and a second position when the wearer puts on the sport helmet, wherein the rear support  260  and occipital inner pad  18  are deflected towards the inner surface  30  of the rear shell portion  22  while the rear support  260  and occipital inner pad  18  maintain pressure on the occipital region OR of the wearer&#39;s head. In this embodiment, the rear support  260  thus comprises five biasing members  262 ,  264 ,  266 ,  268 ,  270 . 
       FIG. 13  shows a rear support  360  according to a third embodiment.

In this embodiment, rear support  360  thus comprises three biasing members  362 ,  364 ,  366 . 
       FIG. 14  shows a rear support  460  according to a third embodiment. The rear support  460  has left and right middle biasing members  462 ,  464 , each of the biasing members  462 ,  464  extending rearwardly towards the inner surface  30  of the real shell portion  22 , along an acute angle with respect to a longitudinal axis parallel to the longitudinal axis LA, and having a distal end portion abutting the inner surface  30  of the real shell portion  22  such that the rear support  460  and occipital inner pad  18  are movable between a first position, wherein the rear support  460  is biased to extend inwardly from the inner surface  30  of the rear shell portion  22 , and a second position when the wearer puts on the sport helmet, wherein the rear support  460  and occipital inner pad  18  are deflected towards the inner surface  30  of the rear shell portion  22  while the rear support  460  and occipital inner pad  18  maintain pressure on the occipital region OR of the wearer&#39;s head. In this embodiment, the rear support  460  thus comprises two biasing members  462 ,  464 . 
       FIG. 15  shows a rear support  560  according to a third embodiment. The rear support  560  has a central biasing members  562  extending rearwardly towards the inner surface  30  of the real shell portion  22  along an acute angle with respect to a longitudinal axis L parallel to the longitudinal axis LA and having a distal end portion abutting the inner surface  30  of the real shell portion  22 , such that the rear support  560  and occipital inner pad  18  are movable between a first position wherein the rear support  560  is biased to extend inwardly from the inner surface  30  of the rear shell portion  22 , and a second position when the wearer puts on the sport helmet, wherein the rear support  560  and occipital inner pad  18  are deflected towards the inner surface  30  of the rear shell portion  22  while the rear support  560  and occipital inner pad  18  maintain pressure on the occipital region OR of the wearer&#39;s head. In this embodiment, the rear support  560  thus comprises one biasing member  562 . 
     While the biasing member shown in the drawings may take the form of an elongated leg, arm or projection, which has a proximal end portion integrally formed with the lower member of the rear support, projects rearwardly and upwardly from the lower member of the rear support towards the inner surface  30  of the real shell portion  22  and along an acute angle with respect to a longitudinal axis parallel to the longitudinal axis LA and which has a distal end portion for abutting the inner surface  30  of the real shell portion  22 , such that the rear support is biased to extend inwardly from the inner surface  30  of the rear shell portion  22  in the first position, it is understood that the biasing member may alternatively be a separate or integrated spring, spring blade, C- or V-shaped member located between the inner surface  30  of the rear shell portion  22  and the rear support and/or any alternative construction providing a biasing or spring effect such that the rear support returns to its original position (i.e., first position) when pressure is no longer applied on the rear support and occipital inner pad and such that the rear support is biased to extend inwardly from the inner surface  30  of the rear shell portion  22 . For example, the biasing member may comprise four springs or elongated legs made of a resilient material located equidistantly with respect to the rear support, each of the springs or legs having a proximal end portion and a distal end portion, the proximal end portion being mounted to the rear shell portion or the rear support and the distal end portion abutting the rear support or the real shell portion, such that the rear support is biased to extend inwardly from the inner surface of the rear shell portion in the first position. It is therefore understood that a skilled person in the art would design the biasing member(s) such that they are made of any suitable resilient material and have any suitable construction, shape or orientation in order that the rear support is biased to extend inwardly from the inner surface of the rear shell portion when the sport helmet is not worn by the wearer. When the wearer puts on the sport helmet, the rear support and occipital inner pad are deflected towards the inner surface of the rear shell portion while the rear support and occipital inner pad maintain pressure on the occipital region OR of the wearer&#39;s head and such that this pressure is as much as possible evenly distributed or exerted on the occipital region OR in order to avoid pressure point. 
     While hinging of the rear support between the first and second positions is mainly provided in part by the resiliency or bendability of the biasing member(s), it is understood that such hinging may be also provided by the bendability of the remainder of the rear support. For example, hinging of the rear support between the first and second positions may be provided in part by the bendability of the upper member  162  and left and right members  174 ,  176 . 
     The above description of the embodiments should not be interpreted in a limiting manner since other variations, modifications and refinements are possible within the scope of the present invention. The scope of the invention is defined in the appended claims and their equivalents.
