Football helmet with movable shell segment
A protective helmet comprises a shell having an inner surface and an outer surface, and a shell segment movable relative to the shell; an energy absorbing layer having an inner surface, and an outer surface which contacts the inner surface of the shell; and internal padding operably coupled to the inner surface of the energy absorbing layer. The shell has a perimeter and the shell segment is formed by at least one slot channel in the shell which does not extend to the perimeter of the shell. The shell segment moves relative to the shell upon the helmet receiving an impact force. The slot channel is generally U-shaped.
1. A protective helmet comprising:
a shell having an inner surface and an outer surface, the shell comprising a shell segment movable relative to the shell;
an energy absorbing layer adjacent the inner surface of the shell, the energy absorbing layer having an inner surface and an outer surface; and
internal padding operably coupled to the inner surface of the energy absorbing layer;
wherein the shell has a perimeter and the shell segment is formed by at least one slot channel in the shell, the slot channel partially surrounds the shell segment and does not extend to the perimeter of the shell, the shell segment is joined to the shell at a remainder portion of the shell segment not surrounded by the slot channel;
the shell segment moves relative to the shell upon the helmet receiving an impact force; and
the slot channel is U-shaped.
2. The protective helmet as recited in claim 1 , further comprising an inner shell disposed between the energy absorbing layer and the internal padding.
3. The protective helmet as recited in claim 2 , wherein the inner shell is a hard shell.
4. The protective helmet as recited in claim 1 , wherein the shell segment is located in a front portion of the shell.
5. The protective helmet as recited in claim 1 , wherein the shell segment is located in a crown portion of the shell.
6. The protective helmet as recited in claim 1 , wherein the shell segment is located in a rear portion of the shell.
7. The protective helmet as recited in claim 1 , wherein the shell segment is located in a side portion of the shell.
8. The protective helmet as recited in claim 1 , wherein the energy absorbing layer is directly secured to the inner surface of the shell by at least one mechanical fastener.
9. The protective helmet as recited in claim 8 , wherein the mechanical fastener is a threaded fastener.
10. The protective helmet as recited in claim 1 , further comprising a plurality of vent openings disposed through the shell.
11. The protective helmet as recited in claim 1 , wherein the shell comprises a plastic.
12. The protective helmet as recited in claim 11 , wherein the plastic is at least one of a polycarbonate or an ABS plastic.
13. The protective helmet as recited in claim 1 , wherein the slot channel is continuous.
14. The protective helmet as recited in claim 1 , wherein the shell segment is movable about the remainder portion to move into the energy absorbing layer.
15. The football helmet as recited in claim 1 , wherein the shell segment is movable about the remainder portion.
16. A football helmet comprising:
a one-piece shell having an inner surface and an outer surface, the shell comprising a shell segment formed by a slot channel that at least partially surrounds the shell segment to allow the shell segment to be movable relative to the shell;
ear holes formed in the shell;
an energy absorbing layer having an inner surface and an outer surface and the outer surface of the energy absorbing layer contacting the inner surface of the shell; and
internal padding operably coupled to the inner surface of the energy absorbing layer;
wherein the shell has a perimeter and the slot channel forming the shell segment is entirely within the perimeter of the shell;
the shell segment is joined to the shell at a remainder portion of the shell segment not surrounded by the slot channel; and
wherein the shell segment moves relative to the shell upon the helmet receiving an impact force.
17. The football helmet as recited in claim 16 , further comprising an inner shell disposed between the energy absorbing layer and the internal padding.
18. The football helmet as recited in claim 17 , wherein the inner shell is a hard shell.
19. The football helmet as recited in claim 16 , wherein the shell segment is located in a front portion of the shell.
20. The football helmet as recited in claim 16 , wherein the shell segment is located in a crown portion of the shell.
21. The football helmet as recited in claim 16 , wherein the shell segment is located in a rear portion of the shell.
22. The football helmet as recited in claim 16 , wherein the shell segment is located in a side portion of the shell.
