Helmet for a hockey or lacrosse player
View Patent ↗A helmet for receiving the head of a hockey or lacrosse player, the helmet having an outer shell and an inner lining covering at least partially the inner surface of the outer shell. In one embodiment, the helmet comprises a skeleton at least partially covered by the inner lining, a movable occipital pad and movable temple pads. The inner lining can be made of an absorptive material such as foam, expanded polypropylene or expanded polyethylene and can be overmolded onto the skeleton. The occipital pad and the temple pads may be arranged with an inward bias so as to help the helmet self-adjust to provide an advantageous fit on the player's head. In some embodiments, the outer shell and skeleton, or the outer shell and the inner lining, cooperate to define a ventilation system.
1. A helmet for receiving the head of a hockey or lacrosse player, said helmet extending along a longitudinal axis and comprising:
(a) an outer shell for covering at least a portion of the head, said outer shell having an inner surface and an outer surface;
(b) a skeleton mounted within said outer shell, said skeleton being made of a semi-rigid material and having an inner surface and an outer surface, said skeleton comprising a plurality of members, said plurality of members comprising at least one member having first and second projecting walls, a bottom wall extending between said first and second projecting walls, and an elongated channel defined between said first and second projecting walls and extending along said first and second projecting walls and said bottom wall, each of said first and second projecting walls extending upwardly from said bottom wall at an angle higher than 90° relative to said bottom wall and towards said inner surface of said outer shell such that, in use, said first and second projecting walls are adapted to deflect upon an impact to said outer shell; and
(c) an inner lining at least partially covering said inner surface of said skeleton, said inner lining having an inner surface for contacting a substantial portion of the player's head.
2. A helmet as defined in claim 1 , wherein said at least one member has a substantially U shaped cross-section.
3. A helmet as defined in claim 1 , wherein said at least one member has a substantially V shaped cross-section.
4. A helmet as defined in claim 1 , wherein said skeleton is made of a semi-rigid polymer.
5. A helmet as defined in claim 1 , wherein said skeleton is made of polypropylene reinforced with fibers.
6. A helmet as defined in claim 5 , wherein said fibers are glass fibers.
7. A helmet as defined in claim 1 , wherein said skeleton is made by injection-molding.
8. A helmet as defined in claim 1 , wherein said inner lining is made of expanded polypropylene (EPP) or expanded polyethylene (EPE).
9. A helmet as defined in claim 1 , wherein said inner lining is overmolded onto said skeleton.
10. A helmet as defined in claim 1 , further comprising an occipital pad hingedly mounted adjacent to said inner lining and extending downwardly from said skeleton for facing a portion of an occipital region of the head, said occipital pad being deflectable relative to said outer shell between a first position and a second position, said second position being towards an interior of said helmet relative to said first position, said occipital pad being biased to extend inwardly up to at least ¼ inch from said inner surface of said outer shell in said second position such that, in use, when the player dons said helmet, said occipital pad is deflected so that it exerts a force on the head of the player in said first position.
11. A helmet as defined in claim 1 , further comprising left and right temporal pads extending from said skeleton for facing left and right temples of the head, each temporal pad being deflectable relative to said outer shell between a first position and a second position, said second position being towards an interior of said helmet relative to said first position, said temporal pad being biased to extend inwardly up to at least ⅛ inch from said inner surface of said outer shell in said second position such that, in use, when the player dons the helmet, said temporal pads are each deflected so that said temporal pads each exert a force on the head of the player in said first position.
12. A helmet as defined in claim 1 , wherein said outer shell has a first ventilation aperture and a second ventilation aperture and wherein said elongated channel of said at least one member is in air communication with one of said front and rear ventilation apertures such that, in use, airflow is provided within said elongated channel.
13. A helmet as defined in claim 12 , wherein said at least one member is a left side member extending along an axis generally parallel to said longitudinal axis and said front and rear ventilation apertures are first front and rear ventilation apertures, wherein said outer shell further comprises second front and rear ventilation apertures and wherein said skeleton further comprises a right side member extending along an axis generally parallel to said longitudinal axis, said right side member having first and second projecting walls and a bottom wall extending therebetween, each projecting wall extending upwardly from said bottom wall of said right side member at an angle higher than 90° relative to said bottom wall and towards said inner surface of said outer shell, and wherein said first and second projecting walls and said bottom wall define a second elongated channel in air communication with one of said second front and rear ventilation apertures such that, in use, airflow is provided in said second elongated channel.
14. A helmet as defined in claim 13 , wherein said first rear ventilation aperture is configured such that, in use, air flowing front-to-back over said outer shell is drawn out of said first rear ventilation aperture due to a venturi effect.
15. A helmet as defined in claim 14 , wherein said second rear ventilation aperture is configured such that, in use, air flowing front-to-back over said outer shell is drawn out of said second rear ventilation aperture due to a venturi effect.
16. A helmet for receiving the head of a hockey or lacrosse player, said helmet comprising:
(a) an outer shell for covering at least a portion of the head, said outer shell having a front portion with a first ventilation aperture, a rear portion with a second ventilation aperture, an inner surface and an outer surface;
(b) a skeleton mounted within said outer shell, said skeleton being made of a semirigid material and having an inner surface and an outer surface, said skeleton comprising a plurality of members, said plurality of members comprising at least one member having first and second projecting walls, and a bottom wall extending between said first and second projecting walls, and an elongated channel defined between said first and second projecting walls and extending along said first and second projecting walls and said bottom wall, each of said first and second projecting walls extending upwardly from said bottom wall and towards said inner surface of said outer shell, said elongated channel being in air communication with said first and second ventilation apertures such that, in use, airflow is provided within said elongated channel; and
(c) an inner lining at least partially covering said inner surface of said skeleton.
17. A helmet as defined in claim 1 , wherein said outer shell comprises a front shell portion and a rear shell portion and wherein, in use, said front and rear shell portions are movable relative to one another so as to adjust the size of said helmet.
18. A helmet as defined in claim 17 , wherein said skeleton comprises a front skeleton portion mounted within said front shell portion and a rear skeleton portion mounted within said rear shell portion.
19. A helmet as defined in claim 18 , wherein said front and rear skeletons are movable relative to one another when said front and rear shell portions are moved relative to one another.
20. A helmet as defined in claim 17 , wherein said inner lining is overmolded onto said front and rear skeleton portions.
