摘要

The seat (10) has a lever (9) which by rotation about an articulation point (3) moves the seat and backrest from a lockable position into a sitting position with variable opening angle between seat and backrest to produce a balanced rocking action. The rotation lever can be varied in length to lock the seat in its incline and allow additional individual adjustment of the backrest.
