Vehicle seat
First Claim
1. A vehicle seat, the seat comprising a squab and a back the back being mounted for pivotal movement relative to the squab of the seat incorporating energy absorbing force limiting means 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, if a vehicle in which the seat is mounted is involved in a rear impact the energy absorbing force limiting means providing a first resistive force resisting the pivotal movement during a first determined pivotal movement, and second resistive force during a second subsequent pivotal movement, the resistive force provided during the first pivotal movement being dependent upon the energy of the rear impact.

Abstract
A vehicle seat includes a squab and a back mounted for pivotal movement relative to the squab. A support plate is mounted to the squab, and the back of the seat is pivotally mounted to the support plate. A mechanism for providing a resistive force resists a first pivotal movement. The providing mechanism provides a first resistive force during a first energy impact and a second resistive force during a second energy impact. The first energy impact is a higher energy impact than the second energy impact.
