Abstract

A helmet assembly includes an upper member, a lower member, and rigid or semi-rigid plates connected between the two members. The helmet may include a series of fluidly connected air compartments beneath the plates is disclosed. Embodiments of the helmet may dissipate impact energy in multiple ways including deformation of the plates, shifting of the plates, cushioning of the plates against a resilient compressible material present in the upper member, compression of air within the air compartments, movement of air within the air compartments, and/or expansion of air in non-impacted sections of the air compartments which causes the shifting of non-impacted plates. Springs with or without resilient, compressible inserts may be positioned between movable plates and a frame member. A spine including compressible material may extend along a top section of the helmet and connect plates on opposite sides of the helmet.
