Abstract
A synchronous adjusting device for a chair is provided where the restoring movement of a back part is effected as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this purpose, the back part is mounted rotatably relative to the seat part at a distance in height. The leaning force of the user at the back leaning point is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part.
