Abstract

A back rest for a vehicle seat comprises an outer frame (9) and a inner support member (12) which is located inside the outer frame (9). A number of spring means (1) are provided between the frame (9) and the support member (12), the spring means having limited elongation length. Each one of the spring means (1) has two anchorage members (3, 4) and one limiter device (5) for limiting the elongation length. The limiter device (4) extends approximately between the two anchorage members (3, 4). The limiter device (5) has a free end which is provided with an engagement member (6) which is intended to engage with an arrest member on elongation of the spring (1).
