ABSTRACT The inclination of the seat and back rest of an adjustable office chair can be varied and locked in a desired position. A clamping bolt arrangement consists of a set of plates with friction discs on each side of each plate. A bolt extends through the plates and friction discs and the assembly is supported in the seat carrier for free axial movement. An eccentrically mounted lever, which is self-locking in either position, controls the tension on the bolt and hence the locking of the plates. Since the lever requires only a short path of travel the assembly is suitable for mass production.
