Claim Text:
1. A shock absorbing layer for a helmet, the layer comprising: a base plate; and a plurality of spaced apart shock absorbing members disposed on the base plate and interconnected only therethrough, each of the shock absorbing members being independently and elastically collapsible to at least partially absorb an impact load on the helmet, the shock absorbing members being hollow and defining a closed perimeter wall extending upwardly from the base plate to an open top end sized to cause negligible reduction of fluid flow exiting the shock absorbing member, the closed perimeter wall of each said shock absorbing member including at least one wall section, each wall section having: a first portion having opposed inner and outer surfaces each having the shape of a frustum, and a second portion extending upwardly from the first portion and being integrally formed therewith, the second portion having opposed inner and outer surfaces each having the shape of a frustum, wherein the inner surfaces of the first and second portions are interconnected through relatively radially wider ends of their respective frustums to define an inner angle between the inner surfaces of the first and second portions of less than 180 degrees, and the outer surfaces of the first and second portions are interconnected through relatively radially wider ends of their respective frustums to define an outer angle between the outer surfaces of the first and second portions of greater than 180 degrees.
