Abstract (en)

[origin: WO9724958A1] The invention concerns the height-adjustment of the back-rests of chairs, especially office chairs, consisting of a housing (1) in which a flat back-rest carrier (2) is held by a ball-stop clamp (3, 4), the back-rest carrier (2) being provided with a series of indentations or holes (3) arranged behind one another in an axial direction for the stop-balls (4) which are held in the indentations or holes (3) by means of a spring-loaded clamping bevel (5'). The clamping bevel (5') can be brought out of contact by a push-button (8) guided sideways from outside the housing against the spring force, spring-loaded means (10, 11) being arranged in the housing (1) for the prevention of sideways play of the back-rest carrier (2).
