Abstract:
The adjusting mechanism serves for the weight-dependent setting of a restoring force which acts on a backrest (4) of an office chair which is configured with a synchronous mechanism. The synchronous mechanism comprises a support (12), a seat support (10) and a backrest support (8) which are connected to one another via joint pins (A1-A4), the restoring force being exerted via a spring element (18). In order to achieve as flat a design as possible, the restoring force is transmitted with the aid of a pivotable lever (16) via a front bearing pin (L1) to a first front joint pin (A1), an active lever length (h) which can be varied with the aid of an adjusting element (20) being defined by the spacing between the bearing pin (L1) and the second front joint pin (A2). A weight setting is made possible by the variation of the active lever length (h).
