Abstract
A hard hat and related impact protection layer is shown. The hard hat includes one or more feature to improve support of the impact protection layer. The impact protection layer is designed to improve impact energy absorption provided by a crushable material located within the hard hat shell.
Claims20
A hard hat, comprising:
- an outer shell comprising:
- an exterior surface;
- an interior surface defining a cavity;
- a crown portion positioned in a central area of the hard hat surrounding a center point;
- and
- a bottom portion defining a lower circumference extending along the exterior surface;
- and
- an impact protection layer positioned within the cavity, the impact protection layer comprising:
- a first piece supported at a first location within the cavity;
- and
- a second piece supported at a second location within the cavity;
- wherein the first piece and the second piece of the impact protection layer have a non-uniform stiffness such that each piece has a first compression axis having a first stiffness and a second compression axis having a second stiffness, and wherein the first stiffness is greater than the second stiffness.
