Abstract

Abstract Secondary energy absorbing helmet underwear is to be worn by a user under a primary rigid hard hat, sports helmet or military helmet. The helmet underwear includes an integral self elasticized stretchable material that includes a three-dimensional structure that is generally of semi-spherical shape to fit about the users head and that includes an optional peripheral stretchable stretch band that provides a means for retaining the helmet underwear in place on the users head. The stretchable material and core includes front and rear layers that are each formed as a knitted layer and interconnecting yarns that interconnect between the front and rear layers and define a predetermined spacing between the front and rear layers. The interconnecting yarns, in combination with the layers provide a safety barrier between the rigid hat and the user's head.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 237 words
Energy absorbing helmet underwear that is adapted to be worn by a user under a rigid hard hat or the like and comprising: a pair stretchable fabric shells; a shock absorbing core material that is disposed between said shells; and a stretch band attached to the fabric shells to enable the headpiece to be fitted over the user's head while the shock absorbing core material provides a safety barrier between the rigid hat and the user's head; wherein the shock absorbing core material comprises an energy absorbing core layer that is a three-dimensional warp knit spacer fabric; wherein the stretchable fabric layers have a greater elasticity that the energy absorbing core layer; wherein the energy absorbing core layer is disposed in a pocket defined between the stretchable fabric layers and is free-floating therein without any fastening means between the stretchable fabric layers and the energy absorbing core layer; wherein, when the energy absorbing underwear is off the head of the user, the energy absorbing core layer substantially fills the entire pocket between the stretchable fabric layers; wherein, when the energy absorbing underwear is applied to the head of the user, then the stretchable fabric layers stretch relative to the energy absorbing core layer leaving a slight gap on either end of the energy absorbing core layer; and wherein the stretch band is a continuous annular-shaped band that is adapted to fit about the head of the user.
Claim 2
Dependent Claim 237 words
Energy absorbing helmet underwear that is adapted to be worn by a user under a rigid hard hat or the like and comprising: a pair stretchable fabric shells; a shock absorbing core material that is disposed between said shells; and a stretch band attached to the fabric shells to enable the headpiece to be fitted over the user's head while the shock absorbing core material provides a safety barrier between the rigid hat and the user's head; wherein the shock absorbing core material comprises an energy absorbing core layer that is a three-dimensional warp knit spacer fabric; wherein the stretchable fabric layers have a greater elasticity that the energy absorbing core layer; wherein the energy absorbing core layer is disposed in a pocket defined between the stretchable fabric layers and is free-floating therein without any fastening means between the stretchable fabric layers and the energy absorbing core layer; wherein, when the energy absorbing underwear is off the head of the user, the energy absorbing core layer substantially fills the entire pocket between the stretchable fabric layers; wherein, when the energy absorbing underwear is applied to the head of the user, then the stretchable fabric layers stretch relative to the energy absorbing core layer leaving a slight gap on either end of the energy absorbing core layer; and wherein the stretch band is a continuous annular-shaped band that is adapted to fit about the head of the user.
Claim 3
Dependent Claim 12 words
The helmet underwear of claim 1 including stitching through the stretch band.
