Abstract
A vehicle seat comprising a rigid support structure provided with a rear central beam, which structure carries a headrest, a seat proper, and a seat back carried by the central beam. The seat back is pivotally mounted on the central beam via two couplings that enable the seat back to move rearwards, under a force greater than a predetermined limit value.
Claims10
A vehicle seat comprising a rigid support structure, a seat proper, a seat back provided with a rigid framework carried by the support structure, and a headrest, the framework of the seat back being connected to the support structure via at least first and second couplings that are disposed at different heights and that are adapted:
- normally, to hold the seat back in an in-use position;
- and
- when the seat back is subjected to high rearward stress, greater than a predetermined limit, to enable at least a top portion of the seat back to move rearwards at least to a safety position;
- in which seat the support structure comprises a substantially vertical central beam connected to the framework of the seat back by the first and second couplings, said central beam carrying the headrest.
