A helmet includes an outer shell with an inner and outer surface, a first impact mitigation layer of a first stiffness coupled to the inner surface of the outer shell, a supplemental shell coupled to the outer surface of the outer shell, and a second impact mitigation layer having a second stiffness positioned between the outer surface of the outer shell and an inner surface of the supplemental shell. The supplemental shell can flex from a first position to a second position upon impact to the supplemental shell. A difference between the first stiffness and second stiffness allows the first and second impact mitigation layers to absorb impacts of different impact force. The supplemental protection component can be optimized for protection against impacts experienced by a particular position, including the location on the helmet, shape, materials, and impact mitigation structures.

Supplemental impact mitigation structures for a helmet

Protective clothing and/or equipment may comprise a modular helmet assembly which comprises a plurality of impact mitigation modules positioned between an outer layer and an interior layer of the helmet, optionally with a plurality of perforations or openings in an outer shell of the helmet. The plurality of impact mitigation assemblies may comprise an impact absorbing array of impact mitigation structures having at least one filament and a lateral support wall or connecting element. When force is applied to the exterior surface, the structures of the impact absorbing materials deform in a desired and controlled manner, reducing the force received by the interior layer.
