The backrest support comprises an actuator (9) e.g. bolt or ball head, which stays in an effective communication with a seat support (3). The seat support is downwardly moved in a displacement direction during pivot movement of the backrest in a pivoting direction. The seat support is connected with the base support by a partial non-linear function.</p> |
