The helmet may further comprise left and right locking mechanisms for retaining the front and rear portions 12, 14 in the position selected by the player. Any suitable type of locking mechanisms can be used without departing from the spirit of the invention.
In use, a player 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. The player must simply release the locking mechanism, expand or contract the size of the helmet 10 by displacing the front and the rear portions 12, 14 in relation to each other in the appropriate direction, and close the locking mechanism when the internal size of the helmet is adequate.
Alternatively, the helmet 10 may comprise a non-adjustable one-piece shell covering one or more inner pads. In another possible variant, the helmet 10 may comprise separate front and rear portions 12, 14 that are connected to one another in any suitable way but not adjustable one relative to the other.
As best shown in Figures 3 and 4, the rear shell 18 comprises an elongated slot 34 extending along the longitudinal axis A-A of the helmet 10.
Figures 5 and 6 show an occipital adjustment mechanism comprising an occipital inner pad 36 for facing the occipital region OC, a central member 38 extending along the longitudinal axis of the helmet 10, the central member 38 comprising an upper part 40 hingedly mounted with respect to the rear shell 18 and a lower part 42 mounted to the occipital inner pad 36, a single wedging member 44 located between the rear shell 18 and the central member 38 and a single actuator 46 connected to the single wedging member 44 and being accessible to the player such that, in use, the player can move the single wedging member 44 from a first position to a second position.
The front and rear portions 12, 14 (front and rear shells 16, 18 more particularly) can move one with relation to the other so as to adjust the size of the head receiving cavity of the helmet 10. The helmet may further comprise left and right locking mechanisms for retaining the front and rear portions 12, 14 in the position selected by the player. Any suitable type of locking mechanisms can be used without departing from the spirit of the invention.
In use, a player 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. The player must simply release the locking mechanism, expand or contract the size of the helmet 10 by displacing the front and the rear portions 12, 14 in relation to each other in the appropriate direction, and close the locking mechanism when the internal size of the helmet is adequate.
Alternatively, the helmet 10 may comprise a non-adjustable one-piece shell covering one or more inner pads. In another possible variant, the helmet 10 may comprise separate front and rear portions 12, 14 that are connected to one another in any suitable way but not adjustable one relative to the other.
As best shown in Figures 3 and 4, the rear shell 18 comprises an elongated slot 34 extending along the longitudinal axis A-A of the helmet 10.
Figures 5 and 6 show an occipital adjustment mechanism comprising an occipital inner pad 36 for facing the occipital region OC, a central member 38 extending along the longitudinal axis of the helmet 10, the central member 38 comprising an upper part 40 hingedly mounted with respect to the rear shell 18 and a lower part 42 mounted to the occipital inner pad 36, a single wedging member 44 located between the rear shell 18 and the central member 38 and a single actuator 46 connected to the single wedging member 44 and being accessible to the player such that, in use, the player can move the single wedging member 44 from a first position to a second position.
7 , The wedging member 44 has a thickness that increases gradually from its top edge up to its bottom edge as best shown in Figure 6. Because of its increased thickness, the wedging member 44 therefor acts as a wedge wherein vertical upward displacement of the single wedging member 44 between the rear shell 18 and the central member 38 moves the occipital inner pad 36 from its first position, shown in Figures 7A and 8A, towards its second position, shown in Figures 8A
and 8B, wherein the occipital inner pad 36 applies a greater pressure upon the occipital region OC.
As shown in Figures 7A and 8A, in the first position, the occipital inner pad applies a first pressure upon the occipital region OC. As shown Figures 7B and 8B, in the second position, the occipital inner 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 in Figures 7A and 8A to the second position shown in Figures 7B and 8B. In the second position, the occipital inner 36 applies pressure upon the occipital region 00 for urging the front portion 12 (the front 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 occipital inner pad 36 induces a corresponding movement of the helmet 10 towards the back of the head, necessary to seat the front portion 12 of the helmet 10 against the crown region CR.
