Abstract
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.
