ABSTRACT:
An energy attenuating apparatus for use with a seat includes an elongated attenuator having a resistance to bending which varies along its length. A bending mechanism defining a nonlinear path receives the attenuator. Translation of the bending mechanism relative to the attenuator in a lengthwise direction of the attenuator produces bending of the attenuator to absorb energy applied to the energy attenuating apparatus.
