Abstract

The chair, particularly an office chair, has a seat support (14) and a rest support (12) that is tilted around a rest rotating axis (20). A weight mechanics is provided for the automatic weight-dependent adjustment of a restoring force operating on the rest support. The restoring force is transmitted to the rest support by an articulation element. A greater lever length is set as the weight burden increases.
