ABSTRACT:
A reclining chair is disclosed containing a conventional seat portion pivotable about a fixed pivot shaft or axle and a backrest containing a backrest plate displaceable upon guide rails. These guide rails are pivoted to a greater extent than the seat during the rearward reclining of the seat, due to the action of a guide element connected with a piston rod of a pneumatic spring arrangement. Due to the movement of the guide element there is rotated a transmission lever pair about a stationary pivot shaft, the transmission lever pair being connected with the guide element. A curved entrainment member, hingedly connected with this transmission lever pair, is connected with the backrest plate. Since a pivot shaft between the transmission lever pair and the curved entrainment member moves through an appreciably larger distance than the connection location between the seat and the guide element or the guide rails, the backrest plate is downwardly drawn along the guide rails. By virtue of this adjustment mechanism there is ensured that the backrest plate follows that course of movement which is performed by the back of the user during reclining of the chair.
