helmet 10 may comprise a non-adjustable one-piece shell covering one or more inner pads. In another possible variant, thehelmet 10 may comprise separate front andrear portions - As best shown in
Figures 3 and4 , therear shell 18 comprises anelongated slot 34 extending along the longitudinal axis A-A of thehelmet 10. -
Figures 5 and6 show an occipital adjustment mechanism comprising an occipitalinner pad 36 for facing the occipital region OC, acentral member 38 extending along the longitudinal axis of thehelmet 10, thecentral member 38 comprising anupper part 40 hingedly mounted with respect to therear shell 18 and alower part 42 mounted to the occipitalinner pad 36, asingle wedging member 44 located between therear shell 18 and thecentral member 38 and asingle actuator 46 connected to the single wedgingmember 44 and being accessible to the player such that, in use, the player can move the single wedgingmember 44 from a first position to a second position. - The wedging
member 44 has a thickness that increases gradually from its top edge up to its bottom edge as best shown inFigure 6 . Because of its increased thickness, the wedgingmember 44 therefor acts as a wedge wherein vertical upward displacement of the single wedgingmember 44 between therear shell 18 and thecentral member 38 moves the occipitalinner pad 36 from its first position, shown inFigures 7A and8A , towards its second position, shown inFigures 8A and8B , wherein the occipitalinner pad 36 applies a greater pressure upon the occipital region OC. - As shown in
Figures 7A and8A , in the first position, the occipitalinner pad 36 applies a first pressure upon the occipital region OC. As shownFigures 7B and8B , in the second position, the occipitalinner pad 36 applies a second pressure upon the occipital region OC wherein the second pressure is greater than the first pressure. - Hence, the occipital
inner pad 36 faces the occipital region OC and is movable between the first position shown inFigures 7A and8A to the second position shown inFigures 7B and8B . In the second position, the occipital inner 36 applies pressure upon the occipital region OC for urging the front portion 12 (thefront shell 16 and front inner pad 26) towards the crown region CR (as previously indicated, 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 head). - Depending on how tightly the head of the player fits in the head receiving cavity of the
helmet 10, the pressure applied by the occipitalinner pad 36 induces a corresponding movement of thehelmet 10 towards the back of the head, necessary to seat thefront portion 12 of thehelmet 10 against the crown region CR. - Also, depending on how tightly the head of the player fits in the head receiving cavity of the
helmet 10, in the first position, the occipitalinner pad 36 applies a first pressure upon the occipital region OC, and in the second position, the occipitalinner pad 36 applies a second pressure upon the occipital region OC, the second pressure being greater than the first pressure. - The occipital
inner pad 36 may be made of expanded polypropylene (EPP) or expanded polyethylene (EPE) or polyethylene foam or polyethylene foam having two different densities. Other materials can also be used without departing from the spirit of the invention. - The occipital
inner pad 36 may comprise a rear portion and a front portion that is less rigid than the rear portion. For example, the front portion may be made of a soft absorbent material while the rear portion may be made of a rigid plastic-like material or equivalent. One or more comfort liners may be affixed to the inner surface of the occipitalinner pad 36. - As best shown in
Figure 5 , thecentral member 38 is an elongated piece extending along the longitudinal axis A-A of thehelmet 10 from theupper part 40 to thelower part 42. - The
upper part 40 is hingedly mounted with respect to the rear shell 18 (e.g. to the rearinner pad 32 as best shown inFigures 8A and8B ); or to theinner surface 20 of the rear shell 18 (now shown)). As shown inFigures 3 and5 , the rearinner pad 26 may include agroove 48 and a recessedportion 50 to partially accommodate thecentral member 38 and the rearinner pad 26. The rearinner pad 26 may also includeapertures 52 to receive correspondingpegs 54 provided on theupper part 40 such that theupper part 40 is hingedly mounted to the rear inner pad 24. Hinging may be provided in thecentral member 38 by any suitable means, and in the example shown, it is provided by the bendability of all the portion of thecentral member 38 that extends below theupper part 40, and more particularly, the portion of thecentral member 32 located between the upper andlower parts - The
lower part 42 is mounted to the occipitalinner pad 36. In one example as shown inFigure 5 , thelower part 42 is screwed to the occipitalinner pad 36. Other affixing means (e.g. glue, stitches, rivets, tacks, staples) can be used without departing from the scope of the invention. In another example, the central member may be attached to the occipital inner pad by virtue of being integral, and therefore continuous, with the occipital inner pad. In a further example, the central member may be integrally formed with the rear inner pad at its upper part and integrally formed with the occipital inner pad at its lower part. - The
single wedging member 44 may comprise a locking mechanism which can be any suitable mechanism for preventing unintentional movement of the single wedgingmember 44. As shown inFigures 9A and 9B , the locking mechanism comprisesprotrusions 56 provided on the wedgingmember 44 adapted to register betweennotches 58 extending from theinner surface 20 of therear shell 18 and on each side of theelongated slot 34. -
Figure 9A shows the wedgingmember 44 in a lock position. Here the locking mechanism is engaged and theprotrusions 56 register between thenotches 58. When the wedgingmember 44 is in the unlock position, as shown inFigure 9B , the wedgingmember 44 is pushed away from theinner surface 20 of therear shell 18 and theprotrusions 56 no longer register between thenotches 58 such that movement of the wedgingmember 44 is possible. Any other frictional engagement is contemplated for the locking mechanism. For example, a rubber friction surface could also be used. - Referring to
Figures 9A and 9B , thesingle actuator 46 has apost portion 46b extending from abutton portion 46a through theelongated slot 34, passing through an aperture provided in the wedgingmember 44 and having adistal end 46c with a diameter larger than the one of the wedgingmember 44 for securing theactuator 46 to the wedgingmember 44. - The
single actuator 46 can be made of a resilient material having a resiliency such that thepost portion 46b anddistal end 46c pull the wedgingmember 44 towards theinner surface 20 ofrear shell 18 and holds the wedgingmember 44 in the lock position. Thesingle actuator 46 can be made of a resilient material such as NYLONâ„¢ or polyacetal (DELRINâ„¢) that has the characteristic to return to its original shape when pressure is no longer applied on it. In another example, the actuator may comprise a spring for urging the wedgingmember 44 in the lock position. Any other suitable biasing means could be used for urging the wedgingmember 44 in the lock position. - The
single actuator 46 may have a length when relaxed that is shorter than the distance required to connect theactuator 46 to the wedgingmember 44 when the wedging member is in the lock position. As such, the elastomeric material ofactuator 46 may be stretched when the wedgingmember 44 is in the lock position such that a pretension is caused whereby the resilience of the elastomeric material of theactuator 46 pulls the wedgingmember 44 towards theinner surface 20 ofrear shell 18 and holds the wedgingmember 44 in the lock position. - As shown in
Figure 9B , when thebutton portion 46a is pushed by the player towards therear shell 18, it is compressed and thepost portion 46b anddistal end 46c are pushed away from theinner surface 20 of therear shell 18, thus disengaging theprotrusions 56 from thenotches 58 and allowing the wedgingmember 44 to be moved upwardly or downwardly along theelongated slot 34. - As shown in
Figures 7A and7B , therear shell 18 follows a curvature (in a horizontal plane) while the rear surface of the occipitalinner pad 36 extends generally perpendicularly with respect to the longitudinal axis of thehelmet 10. In one embodiment, the rear shell may follow a curvature (in a vertical plane) while the central member may extend along a different curvature when no pressure is applied on it such that the space between the rear shell and central member reduces gradually in an upward direction. Because the space between the inner surface of the rear shell and the central member reduces gradually from the bottom towards the top of the helmet, vertical upward displacement of the single wedging member, which is located in such space, then moves the occipital inner pad towards the second position, wherein the occipital inner pad applies a second pressure upon the occipital region OC that is greater than the first pressure applied upon the occipital region OC when the occipital inner pad is in the first position. - The present invention provides the player of the hockey or
lacrosse helmet 10 with an easy and convenient way to adjust the occipitalinner pad 36. Thesingle wedging member 44 is moveable via thesingle actuator 46 to adjust the position of occipital the occipitalinner pad 36 while thehelmet 10 is being worn. A locking mechanism which may be a series of protrusions provided on the single wedgingmember 44 that register with corresponding notches or indentations projecting from theinner surface 20 of therear shell 18 for preventing the unintentional displacement of the single wedgingmember 44 when the locking mechanism is in the lock position.
