PCT No. PCT/NO91/00115 Sec. 371 Date Jul. 12, 1993 Sec. 102(e) Date Jul. 12, 1993 PCT Filed Sep. 4, 1991 PCT Pub. No. WO92/03951 PCT Pub. Date Mar. 19, 1992.A chair, especially a working/office chair, comprising a seat-supporting frame (3), a seat (1) rotatably mounted in the frame (3) about a first axis (2), a back support (6) rotatably mounted in the frame (3) about a second axis (7) behind the first one, and a coupling device (20) connected between the seat (1) and the back support (6) behind said axes to cause a synchronous movement of the seat (1) in relation to the back support (6). the coupling device (20) consists of a member having a length which can be readjusted with a certain inertia for adjustment of the relative position of the seat (1) and the back support (6), so that the position of the seat (1) in relation to the back (4) can be readjusted by the exertion of a torque on the seat (1) while the back support (6) simultaneously is kept essentially stationary in relation to the frame (3).
