Abstract
A chair (1), in particular a swiveling office chair, has a seat support (6) fastened to a lower part (7) joined in a swiveling fashion with a seat (2) that is motionally coupled with a backrest (3) by a synchronizing sliding guide (5) or by a similar synchronizing mechanism, whereby the seat (2) is supported by a readjusting apparatus (8) that acts against swinging movement. The chair (1) is characterized by the seat support (6) being guided at the lower part (7) in an approximately vertical direction, and by having within the movement transmission path between the backrest (3) and the lower part (7) of the chair, an apparatus (14) for blocking of and/or compensating for movement transmitted to the readjusting apparatus (8) during a backward swiveling movement of the backrest (3). The readjusting force of the backrest (3) is automatically adapted depending on the weight of the person using the chair, and increases with increasing inclination of the backrest. The chair is distinguished by its simple construction and compact design.
