Abstract
Protective headgear configured for protection of a portion of a wearer's head, including a resilient outer shell, a layered composite liner including a multiplicity of deformable layers, each layer having a different stiffness than adjacent layers, and wherein a layer has a higher stiffness than that of adjacent layers on either side, and a retention system configured to resist upward/rearward rotation of the headgear with respect to the wearer's head to expose the forehead, due to hydrodynamic or aerodynamic forces.
Claims7
Protective headgear configured for protection of a portion of a wearer's head, comprising:
- a shell;
- a layered composite liner including a multiplicity of deformable layers, each layer having a different stiffness than adjacent layers, and wherein a layer has a higher stiffness than that of adjacent layers on either side;
- a retention system configured to resist upward/rearward rotation of the headgear with respect to the wearer's head, further comprising a chin strap portion attaching the chin strap portion and fastening means slidably attaching the chin strap portion to the shell at a forward attachment location, said chin strap portion integral with a nape strap portion for extending behind and engaging the wearer's head at the nape of a neck, configured so that when a force is placed upon the shell tending to rotate it up and back so as to expose a wearer's forehead, tension is created in said strap portions, thereby pulling the shell toward the wearer's head, increasing friction between the wearer's head and the headgear and resisting upward/rearward rotation of the headgear with respect to the wearer's head.
Protective headgear configured for protection of a portion of a wearer's head, comprising:
- a shell;
- a liner;
- a retention system configured to resist upward/rearward rotation of the headgear with respect to the wearer's head due to fluid flow against the wearer's head and protective headgear, further comprising a chin strap portion attaching the chin strap portion and fastening means slidably to the shell at a forward attachment location, said chin strap portion integral with a nape strap portion for extending behind and engaging the wearer's head at the nape of a neck, configured so that when a force is placed upon the shell tending to rotate it up and back so as to expose a wearer's forehead, tension is created in said strap portions, thereby pulling the shell toward the wearer's head, increasing friction between the wearer's head and the headgear and resisting upward/rearward rotation of the headgear with respect to the wearer's head.
Protective headgear configured for use in whitewater sporting activities, comprising:
- a shell;
- a liner;
- a retention system configured for resisting shifting of the headgear with respect to a wearer's head, including fastening means for connecting to the shell at a forward attachment location and a rearward connection location, further comprising a strap configured to engage a rearward part of the wearer's head, slidingly attached by said fastening means to the shell at the forward attachment location and extending downward to a chin area of the wearer's head, and a strap which extends between the chin area and the shell, and is fixedly attachable to the shell by said fastening means at the rearward attachment location.
