In a gas spring arrangement, comprising a gas spring disposed between two elements which are pivotable in relation to one another around a pivot axis, which damps the pivot movement, and a mechanical arrangement with an activating lever for the releasable adjustment of the pivot movement, especially for the adjustment of the inclination of the backrest of office chairs, it is provided, on the one hand, to make possible a simple damping of the pivotal movement of the backrest support part relative to the seat carrier and, on the other hand, to make possible the easily operable yet still secure locking of this pivotal movement, that the gas spring (19) is fastened between two transverse struts (bolts 23, 27), each disposed on an element (seat carrier 4, backrest support 7) parallel to the pivot axis (6), that the mechanical adjustment means (29) has a sheath part (31) and a pistion part (30) longitudinally movable in the sheath part (31), that both the sheath part (31) and the piston part (30) are each connected with one of the transverse struts (bolts 23, 27) and are disposed approximately parallel to the gas spring (19), and that the sheath part (31) has a lateral threaded bore (bore 39, threaded top 40), into which a threaded bolt (42) disposed at the front end of the activating lever (43) can be screwed in such a way, that the piston part (30) can be braced against the sheath part (31).

A gas spring arrangement comprising a gas spring, disposed between two elements pivotable in relation to one another around a pivot axis, which damps the pivot movement, and a mechanical arrangement with an activating lever for the releasable adjustment of the pivot movement, especially for the inclination adjustment of the backrest of office chairs, characterized in that the gas spring is fastened between two transverse struts, which are each disposed on an element parallel to the pivot axis, and in that the mechanical adjustment means comprises a sheath part and a piston part longitudinally movable in the sheath part, in that the sheath part and the piston part are each connected with axial free play to one of the transverse struts and are disposed generally parallel to the gas spring, and in that the sheath part has a lateral threaded bore, into which a threaded bolt disposed at the front end of the activating lever can be screwed in such a way that the piston part can be braced against the sheath part, and a spring is disposed on the transvere strut supporting the sheath part, said spring acting on said sheath part parallel to the pivot axis.
