Abstract: An energy absorbing device includes a plastically deformable metal strap for resisting the collapse of a steering column. The strap is initially deformable into one or more V-shaped wave formations by anvils to increase the energy required to advance the strap, thereby increasing the resistance to collapse of the steering column. One of the anvils may be removed to eliminate one of the wave formations and thereby reduce the amount of resistance to collapse of the steering column. Alternatively, the position of an anvil may be varied to vary the shape of a wave configuration from a deep V to a shallow V.
