Abstract

A backrest consists of a lumbar part (1) and a shoulder part (2), which parts are connected to one another via elastic bands (3, 4). The guiding of the relative movement of the shoulder part (2) relative to the lumbar part (1) is effected by convex bars (4, 5) which are mounted movably on the lumbar part (1) and on the shoulder part (2) at their nose-like ends by means of prestressed spring elements (7, 8). The lumbar part (1) and the shoulder part (2) move on the concave rear side of the bars between two well-defined stop positions. <IMAGE>
