Title:
ENERGY-ABSORBING LINERS AND SHAPE CONFORMING LAYERS FOR USE WITH PROTECTIVE HEADGEAR
Document Type and Number:
WIPO Patent Application WO2006089234
Kind Code:
A3
Abstract:
A multilayer shell for use in the construction of protective headgear, the shell including an outer layer, an inner layer, a middle layer disposed between the outer and inner layer which resiliently compresses in response to an impact to the outer layer, and an internal liner disposed inwardly of the inner layer. The middle layer includes a plurality of compressible members, which resiliently compress to absorb the energy of a direct impact to the outer layer and resiliently shear with respect to the inner layer in response to a tangential impact to the outer layer. The inner layer includes an open configuration, which reduces the weight of the shell, provides for greater heat ventila- tion from the head of the user, and permits for visualization of the compressible ele¬ ments. The internal liner is formed from contourable materials which enhance user fit and comfort without compromising user safety.
