Abstract
A safety helmet, for example, usable in sports such as football, is shown and described. The safety helmet includes an outer shell and an inner shell. The latter encircles a head of a wearer of the safety helmet. The outer shell is coupled in spaced apart relation to the inner shell by impact attenuators that include in one variation elastically deformable pins. The pins protrude through the inner shell to the inner head seating structure, and outside the inner shell to the outer shell. In another version of the impact attenuators, the pins are bound to a lattice construction providing openings further accommodating deformation responsive to impact forces. Inner and outer shells may have holes to accept ends of the pins. The number of holes may exceed those actually occupied by ends of pins, thereby providing adjustability in number and location of either version of impact attenuator.
