Head protection system and method

1. A system for securing a helmet to the head of a user, comprising:

a helmet body;

at least one strap;

a roll cage disposed substantially within the helmet body; and

a strap hanger coupled to the roll cage, the strap hanger directly and rotatably coupled to the roll cage and not integrally formed with any part of the roll cage, the strap hanger having a slot portion that protrudes out from the helmet body and operable to slidably secure the strap, the strap coupled to the roll cage so that a load on the strap is transferred to the roll cage before being transferred to the helmet body.

2. The system of claim 1 , wherein the helmet body comprises a rear portion, and the slot portion is disposed at the rear portion.

3. The system of claim 1 , wherein the strap hanger is formed from a plastic material.

4. The system of claim 1 , wherein the helmet body comprises a inner surface having a first curvature and defining a recess, and wherein the slot portion is positioned at least partially in the recess and comprises a face having a second curvature that is substantially equal to the first curvature of the inner surface.

5. A system for head protection, comprising:

a helmet body having an outer surface and defining a plurality of holes disposed in a pattern, the helmet body comprising a first material;

a protective layer comprising a second material and coupled to at least a portion of the outer surface;

a roll cage disposed substantially within the helmet body; and

a support layer defining a plurality of openings disposed in a substantially same pattern as the pattern of the holes defined by the helmet body, the support layer disposed at least partially within the helmet body, the support layer comprising carbon fiber or kevlar and positioned so that each opening at least partially aligns with a particular one of the holes defined by the helmet body.

6. The system of claim 5 , wherein the first material comprises expandable polystyrene, and the second material comprises polycarbonate plastic.

7. A system for head protection, comprising:

a helmet body having an outer surface and defining a plurality of holes disposed in a pattern, the helmet body comprising a first material;

a protective layer comprising a second material and coupled to at least a portion of the outer surface;

a roll cage disposed substantially within the helmet body; and

a support layer disposed at least partially within the helmet body, the support layer comprising a third material that is tougher than the first material.

8. The system of claim 7 , wherein third material comprises carbon fiber.

9. The system of claim 7 , wherein third material comprises thermoplastic composite laminate.

10. The system of claim 7 , wherein the support layer defines a plurality of openings disposed in a substantially same pattern as the pattern of the holes defined by the helmet body.

11. The system of claim 7 , wherein the first material comprises expandable polystyrene, and the second material comprises polycarbonate plastic.
