Abstract
An energy absorption apparatus for protecting occupants of different body weights from the effects of excessive G-force by absorbing energy imparted on a vehicle during an explosion occurring below the vehicle. The apparatus has a first mounting member attached to the vehicle, a second mounting member attached to the occupant's seat, and an absorption mechanism attached between the first and second mounting members. The absorption mechanism utilizes an attenuation strip provided on one of the mounting members, and anvils provided on the other of the mounting members such that when the vehicle is subjected to excessive G-force, the attenuation strip is bent and pulled through the anvils thereby producing a frictional attenuation force which controls movement of the seat relative to the vehicle. An absorption adjustment mechanism is provided. Methods of protecting a vehicle occupant from the effects of excessive G-force are also provided.
