Abstract
A new and novel impact energy attenuation material, impact energy attenuation module employing the material and a fit system for optimizing the performance thereof is provided. Non-linear energy attenuating material consisting of a plurality of loose particles is employed for impact energy dissipation. The loose particles are preferably spherical elastomeric balls. An impact energy attenuation module includes a container that holds the loose particles. The impact energy attenuation module can be provided in a wide range of sizes and shapes and the loose particles can be provided in different materials, sizes, density, compaction and hardness to suit with the application at hand. A matrix of impact energy attenuation module are provided about the surface of a shell to provide the required impact energy attenuation. The material, impact energy attenuation module and system of the present invention are well suited for protection of body parts and other cushioning and protection needs.
