ABSTRACT Upon a support part (1) a seat support (3) and a backrest support (4) are connected with a lever (7) by means of pivot joints (5,8). To the backrest end of the seat support (3), a linkage (15) is coupled which is connected at its outer end to a slider (20) and a backrest (21). The linkage (15) causes the slider (20) to move downwards with the backrest (21) during the backward tilting of the chair. In this manner, and in a simple and space saving way, and in particular without occupying the space underneath the seat support (3), the pullout effect can be eliminated during the transition from the normal position to the reclining position of the lever. By the arrangement of a spring device (11), e.g. a gas spring, in the knee-zone of the chair, the blocking of the spring device (11) can be achieved.
