<p>A multilayer shell for use in the construction of protective headgear, the shell including an outer layer, an inner layer, and a middle layer disposed between the outer and inner layer which resiliently compresses in response to an impact to the outer 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.</p> |
