Abstract

A vehicle seat comprises a squab and a back which is mounted for pivotal movement relative to the squab. The seat incorporates an energy absorbing force limiter adapted to absorb energy as the back of the seat moves rearwardly when subjected to a force from the torso of an occupant of the seat, for example, during a rear impact. The energy absorbing force limiter provides a first resistive force resisting the pivotal movement, and a second resistive force during a second subsequent pivotal movement. The resistive force provided during the first pivotal movement is dependent upon the energy of the rear impact. If the rear impact is low energy rear impact, the resistive force is relatively low whereas if the rear impact is a high-energy rear impact, the resistive force is relative high.
