Abstract

Claims (20)

1. A hockey or lacrosse helmet for protecting the head of a player, the hockey or lacrosse helmet comprising:

(a) a rigid outer shell defining an external surface of the helmet, the rigid outer shell comprising a plurality of shell members movable relative to one another to adjust the fit of the helmet on the player's head;

(b) an inner padding configured to conform to the head of the player, the inner padding being configured to decrease a radial acceleration of the head of the player as a result of a radial impact acting against the outer shell, said inner padding comprising a plurality of inner pad members, the inner pad members being associated with respective ones of the shell members so that when the shell members move relative to one another a corresponding movement is imparted to the associated inner pad members;

(c) a rotational impact cushioning arrangement comprising at least one thin and flexible piece of damping material configured to reduce a rotational acceleration of the head of the player as a result of a rotational impact acting against the outer shell, the thin and flexible piece of damping material having a main surface and a thickness, the main surface having an extent that is greater than the thickness, the thin and flexible piece of damping material residing at a location which is adjacent the head of the player when the helmet is worn and the main surface being oriented towards the head of the player when the helmet is worn, the location of the thin and flexible piece of damping material being such that displacement of the shell members relative to one another produces a movement of the thin and flexible piece of damping material relative to at least one of the inner pad members, wherein the thin and flexible piece of damping material is configured such that a rotational impact on the outer shell induces a lateral distortion of the thin and flexible piece of damping material in a direction along the main surface thereof; and

(d) an adjustment mechanism operable by the player and configured to allow the shell members to move relative to one another to perform an adjustment of the fit of the helmet on the player's head.

2. The hockey or lacrosse helmet as defined in claim 1 , wherein the adjustment mechanism includes a hand-operated actuator located on an outer surface of the outer shell.

3. The hockey or lacrosse helmet as defined in claim 1 , wherein the inner padding defines an inner surface configured to face the head of the player, the inner surface including a recessed area receiving the thin and flexible piece of damping material.

4. The hockey or lacrosse helmet as defined in claim 3 , wherein the recessed area is characterized by a depth, the depth being less than a maximal thickness of the thin and flexible piece of damping material.

5. The hockey or lacrosse helmet as defined in claim 1 , wherein the location of the thin and flexible piece of damping material is between the head of the player and the inner padding when the helmet is worn.

6. The hockey or lacrosse helmet as defined in claim 1 , wherein the thickness of the thin and flexible piece of damping material does not exceed 10 mm.

7. The hockey or lacrosse helmet as defined in claim 1 , wherein the thickness of the thin and flexible piece of damping material does not exceed 5 mm.

8. The hockey or lacrosse helmet as defined in claim 1 , wherein the thin and flexible piece of damping material includes an edge portion extending along at least a portion of a periphery of the thin and flexible piece of damping material, the edge portion having a thickness that is different from a portion of the thin and flexible piece of damping material located inwardly of the edge portion.

9. The hockey or lacrosse helmet as defined in claim 8 , wherein the edge of portion forms a ridge.

10. The hockey or lacrosse helmet as defined in claim 1 , wherein the thin and flexible piece of damping material is configured to face a front region of the player's head when the helmet is worn.

11. The hockey or lacrosse helmet as defined in claim 1 , wherein the thin and flexible piece of damping material is configured to face a side region of the player's head when the helmet is worn.

12. The hockey or lacrosse helmet as defined in claim 1 , wherein the thin and flexible piece of damping material is affixed to a shell member of the plurality of shell members.

13. The hockey or lacrosse helmet as defined in claim 1 , including an occipital pad configured for facing an occipital region of the player's head and movable relative to the rigid outer shell between different positions to adjust the fit of the hockey or lacrosse helmet on the player's head.

14. The hockey or lacrosse helmet as defined in claim 13 , wherein the adjustment mechanism is a first adjustment mechanism, the hockey or lacrosse helmet including a second adjustment mechanism operable by the player and configured to adjust a position of the occipital pad relative to the rigid outer shell.

15. The hockey or lacrosse helmet as defined in claim 14 , wherein the thin and flexible piece of damping material is configured to move relative to the head of the player in response to displacement of the occipital pad relative to the rigid outer shell.

16. The hockey or lacrosse helmet as defined in claim 1 , wherein the rotational impact cushioning arrangement includes a plurality of pieces of thin and flexible damping material, the plurality of pieces being located such that the main surfaces thereof are oriented towards different areas of the head of the player when the helmet is worn.
