Title: Adjustment device

Abstract: An adjustment device for an item of furniture comprises two relatively mutually movable parts of which the one is elongate, cylindrical and longitudinally displaceable in relation to the other. A helical spring is disposed with pretensioning about a split sleeve which grips the cylindrical portion. At least one end of the spring is disposed for cooperation with an abutment in communication with the second part. An operating device is connected to the spring for realizing, on actuation between the ends of the spring and about the center axis of the spring, a relative rotational movement which is counter-directed to the pretensioning.
