Abstract
There is proposed a chair, particularly an office chair, of adjustable height and inclination which has a seat support (75), a backrest support (80), a standing column (10) with first gas spring (20) arranged therein, a support member (25) arranged in horizontal plane on the standing column (10), and a first guide rod (65) and a second guide rod (70). The second guide rod (70) is mounted with two struts laterally on the support member (25) and is functionally connected with a transmission mechanism. The transmission mechanism arranged in the support member (25) is developed as an angular gearing which transmits the swinging movement of the second guide rod (70) which is oriented in the direction of the arrow B', on the one hand, by correspondingly arranged swing levers (62, 62') to a second gas spring (60) which is spaced from and parallel to the support member (25) and, on the other hand, via a tensioning device arranged in the support member (25), to the gas spring (20) which is arranged in the standing column (10).
