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) acc
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).

1. 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)
1. 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), said bearing element (38, 40) being 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 also is accommodated in the housing (26) and acts on the torsion bar (20, 22), characterized in that the bearing element (38, 40) arranged in the housing is connected to the actuating drive (46, 48) in the housing with tensile strength so that the actuating drive (46, 48) pulls the bearing element (38, 40) against the torsion bar (20, 22) thereby to push the torsion bar (20, 22) into the recess (66, 68) without placing any significant force on the housing (26) whereby the housing (26) can be made of lightweight material. 2. The adjusting device of claim 1, characterized in that the recess (66, 68) opens toward the actuating drive (46, 48). 3. The adjusting device of claim 1, characterized in that said actuating drive (46, 48) includes a pushing element (42, 44) that is arranged in the housing (26) in position to engage and push an end (34, 36) of (20, 22), that is driven by the actuating drive (46, 48) and that is slidable across the torsion bar (20, 22), the pushing element (42, 44) being loaded in pressure between the torsion bar (20, 22) and the actuating drive (46, 48). 4. The adjusting device of claim 3, characterized in that the radially projecting lever arm (30, 32) fixed on the torsion bar (20, 22) reaches into the housing (26) and the pushing element (42, 44) acts on the end (34, 36) of said lever arm (30, 32). 5. The adjusting device of claim 1, characterized in that the actuating drive (46, 48) is provided with a hollow spindle (58, 60) that is preferably loaded in tension. 6. The adjusting device of claim 5, characterized in that the hollow spindle (58, 60) is attached by one side in a bearing opening (62, 64) in such a manner that it is axially slidable. 7. The adjusting device of claim 1, characterized in that the actuating drive (46, 48), the bearing element (38, 40) and the pushing element (42, 44) form an adjusting mechanism that is axially slidably carried in the housing (26). 8. The adjusting device of claim 7, characterized in that two adjusting mechanisms for pivoting two torsion bars (20, 22) are provided in one single housing (26). 9. The adjusting device of claim 1 characterized in that said bearing element (38, 40) has, at a side of the recess (66, 68) facing toward the center of the housing (26), a projection (70, 72) that extends toward the center of the housing (26) to assist in encompassing and holding the torsion bar (20, 22) in the recess (66, 68) in the bearing element (38, 40). 10. The adjusting device of claim 9 characterized in that said bearing element (38, 40) has, at a side of the recess (66, 68) opposite the projection (70, 72), a rounded or curved surface for facilitating entry of the torsion bar (20, 22) into the recess (66, 68). 11. The adjusting device of claim 2 characterized in that said recess (66, 68) extends into said bearing element (38, 40) at an inclined downward angle and toward one end of the housing (26).
