Abstract (en)
[origin: EP0350748A1] Using the adjusting device (30), the switching ram (26) of a spring apparatus (19) is adjusted from a locking position into an unlocking position of the spring apparatus (19). In this unlocking position, the chair frame, which consists of a seat support (5), a backrest support (7) and a foot part composed of a support column (1) and a support part (2), can be adjusted in its position. Compared to other designs, the locking and unlocking position is set by a single handle (58) of an operating element (31). This causes the adjusting device (30) to be simpler and more easy to operate. <IMAGE>
