Shock Mitigating Materials and Methods Utilizing Spiral Shaped Elements

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
Various embodiments of a spiral shaped element and wavy suture are disclosed for use in a shock mitigating material to dissipate the energy associated with the impact of an object. The shock mitigating material can be used in helmets, bumpers, bulletproof vests, mats, pads, military armor, and other applications. One embodiment, among others, is a shock mitigating material having spiral shaped elements, each having a circular cross section and each being tapered from a large outside end to a small inside end but also having a suture or sutures that can induce shear waves to mitigate the shock pressure and impulse. Another embodiment is a shock mitigating material having sutures (wavy gaps or wavy materials). In this embodiment when the material is impacted, the wavy gap or material will induce a mechanism in shear to dissipate the impact energy.
