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 the piece of furniture on which to lie or for sitting on, with a housing (26) and with a bearing element (38, 40) accommodated in the housing (26) whereas the bearing element (38, 40) is provided with a recess (66, 68) that partially surrounds the torsion bar (20, 22) and in which the 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 bearing element is connected to the actuating drive (46, 48) which are slidably arranged in the housing (26). The actuating drive is in position to engage and push an end (34, 36) of a lever arm (30, 32) radially projecting from and fixed to the torsion bar (20, 22) and received in the housing (26) thereby to place a torgue on the torsion bar (20, 22) which pushes the torsion bar (20, 22) into the recess (66, 68). |
