摘要

The subject matter of the invention is an adjusting device for a piece of furniture on which to lie or for sitting on with at least one swivel part (12, 14) that is pivotally attached, by way of a torsion bar (20, 22), to said piece of furniture on which to lie or for sitting on, with a housing (26) and with a bearing element (38, 40) accommodated in said housing (26), wherein the bearing element (38, 40) is provided with a recess (66, 68) that partially surrounds the torsion bar (20,22) and in which said torsion bar (20, 22) may be introduced so that the adjusting device (24) is attached to the torsion bar (20, 22) with positive fit, and with an actuating drive (46, 48) that is accommodated in the housing (26) and acts on the torsion bar (20, 22). The provision of an adjusting device that is easy to install on the piece of furniture and that can be manufactured at low cost is achieved by the fact that the actuating drive (46, 48) pushes the torsion bar (20, 22) into the recess (66, 68).
