Abstract (en)
[origin: EP0343450A1] The invention relates to a chair, in particular a work chair or office chair, having a seat (20), which is swivellable in the front region about a horizontal swivel axis (12) and which can be altered in inclination, and a backrest (25), which can be forcibly altered overproportionally in inclination by means of an adjusting device in dependence on the alteration of inclination of the seat, in which chair, with an increasing inclination of the seat, the backrest executes an additional relative movement downwards in relation to the facing end of the seat. A simple adjusting device having operationally reliable rotation and pivot bearings results from the fact that swivel levers (13) are linked to support arms (11) of the chair frame on both sides of the seat, the free ends of which swivel levers are mounted fixedly and non-rotationally on the backrest and support the backrest, and that the seat is mounted rotatably approximately in its central region on the swivel levers and is supported in the front region in an articulated manner on the chair frame via at least one carriage lever (17). <IMAGE>
