Abstract:
A vehicle seat comprising a squab, a back and an energy absorbing force limiter arrangement, the back being mounted for pivotal movement relative to the squab of the seat, the squab of the seat incorporating the energy absorbing force limiter arrangement for absorbing 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 limiter arrangement being configured to provide a first resistive force resisting the pivotal movement during a first predetermined pivotal movement of the back of the seat, and a second resistive force during a second subsequent pivotal movement of the back of the seat, the force limiter arrangement being configured such that the energy absorption during the first predetermined pivotal movement is low in a low energy rear impact and high in a high energy rear impact.
