Abstract

A chair which includes a seat portion and a backrest portion as well as a support member for supporting the seat portion. A cylinder piston assembly enables an adjustment of an inclination of the backrest portion with respect to the seat portion, the seat portion is mounted at the support member so as to fix a normal setting of inclination between the seat portion and backrest portion. A first end of the cylinder piston assembly is mounted to the backrest portion by way of a bearing shaft. The bearing shaft is mounted to the chair so as to enable the bearing shaft to be easily removed. A second end of the cylinder-piston assembly is connected to the chair by way of a coupling member which extends transversely of the seat portion. The coupling member includes a pair of axially spaced end portions in which are respectively arranged coaxially disposed bearings adapted to accommodate bearing support pins. The coupling member is constructed so as to enable a removal thereof from the bearing support pins after a removal of the bearing shaft.
