An actuating mechanism for a pivotably mounted actuating arm for driving a flap of a piece of furniture includes a spring device and a transmission mechanism. The spring device includes a spring-loaded setting member and the transmission mechanism converts the movement of the setting member into a pivoting movement of the actuating arm. The transmission mechanism includes at least one pivotably mounted interlever interacting between the setting member and the actuating arm so that interaction between the interlever and the setting member or the actuating arm occurs by a setting contour. The transmission mechanism includes at least one adjustment device to alter the transmission ratio between the movement of the setting member and the pivoting movement of the actuating arm.

The invention claimed is: 1. A positioning mechanism for driving a flap of a piece of furniture, said positioning mechanism comprising: a damping device which dampens a closing movement of the flap; a pivotably mounted positioning arm for being connected to the flap; a spring device for moving said positioning arm, said spring device including a spring-loaded setting member; and a transmission mechanism connected between said positioning arm and said spring device, said transmission mechanism converting a movement of said spring-loaded setting member into a pivoting movement of said positioning arm, wherein said transmission mechanism includes at least one adjustment device to alter the transmission ratio between the movement of said spring-loaded setting member and the pivoting movement of said positioning arm, and wherein said damping device is formed separately from said spring device. 2. The positioning mechanism of claim 1, wherein said transmission mechanism has a pivotably mounted interlever and a thrust roller, and wherein said interlever is acted on on one side by said spring-loaded setting member and on the other side abuts on a positioning contour formed on or attached to said positioning arm via said thrust roller. 3. The positioning mechanism of claim 2, wherein said spring-loaded setting member acts on said interlever at a bearing point, and wherein the position of the bearing point of said spring-loaded setting member on said interlever is adjustable by said at least one adjustment device. 4. The positioning mechanism according to claim 3, wherein said interlever is pivotable about an axis of rotation, and wherein the distance from the bearing point of said spring-loaded setting member to the axis of rotation of said interlever is adjustable by said at least one adjustment device. 5. The positioning mechanism according to claim 2, wherein said spring-loaded setting member acts on said interlever at a bearing point, and wherein a displacement device is disposed on said interlever, by which the bearing point of said spring-loaded setting member is adjustable by said at least one adjustment device. 6. The positioning mechanism according to claim 5, wherein said displacement device includes a rod, along which the bearing point of said spring-loaded setting member is displaceably mounted. 7. The positioning mechanism according to claim 6, wherein said rod is designed as a threaded spindle, on which a gear wheel engages via an intermediate wheel integrally mounted on said threaded spindle. 8. The positioning mechanism according to claim 2, wherein said interlever has a crank guide along which said spring-loaded setting member is movable. 9. The positioning mechanism of claim 1, wherein said spring device has at least two tension springs. 10. The positioning mechanism of claim 1, wherein the said spring-loaded setting member performs a pivoting movement. 11. The positioning mechanism of claim 1, wherein said damping device comprises a rotation damper. 12. The positioning mechanism of claim 1, wherein said spring device has at least two compression springs. 13. The positioning mechanism of claim 1, wherein said spring device is supported on a hinge point and is pivotable with respect to a body of furniture. 14. The positioning mechanism of claim 1, wherein said spring-loaded setting member performs a linear movement. 15. The positioning mechanism of claim 1, wherein said at least one adjustment device includes two adjustment devices to alter the transmission ratio between the movement of said spring-loaded setting member and the pivoting movement of said positioning arm. 16. The positioning mechanism of claim 15, wherein said transmission mechanism further comprises: an interlever connecting said spring-loaded setting member and said positioning arm, wherein said spring-loaded setting member acts on said interlever at a bearing point, and wherein the position of the bearing point of said spring-loaded setting member on said interlever is adjustable by at least one of said adjustment devices. 17. The positioning mechanism of claim 15, wherein the transmission ratio can be differentially varied by said two adjustment devices. 18. The positioning mechanism of claim 15, wherein one of said two adjustment devices is provided for coarse adjustment of the transmission ratio. 19. The positioning mechanism of claim 18, wherein said adjustment device has a rack for coarse adjustment, on which an element adjustable by a user engages with at least one tooth. 20. The positioning mechanism of claim 15, wherein one of said two adjustment devices is provided for fine adjustment of the transmission ratio. 21. The positioning mechanism of claim 20, wherein said adjustment device has a rack for fine adjustment and at least one eccentric cam which can be operated by a user. 22. The positioning mechanism according to claim 21, wherein the adjustment area of said eccentric cam corresponds to the tooth width of said rack. 23. The positioning mechanism of claim 1, wherein said spring-loaded setting member is connected via at least two pivotably linked levers with said positioning arm. 24. The positioning mechanism of claim 23, wherein said spring-loaded setting member acts on one of said two levers at a bearing point, and wherein the position of the bearing point is variable. 25. The positioning mechanism of claim 1, wherein said damping device is a linear damper. 26. The positioning mechanism of claim 1, wherein said damping device comprises a fluid cylinder. 27. The positioning mechanism of claim 1, wherein said damping device comprises a piston rod which is moved into said damping device during the damping stroke. 28. The positioning mechanism of claim 1, further comprising: a plate-shaped mounting member for connecting said positioning mechanism to a vertical inner wall of the piece of furniture; wherein said damping device is disposed on said plate-shaped mounting member. 29. The positioning mechanism of claim 1, wherein a projection is disposed on said positioning arm, said projection engaging said damping device upon closing the flap. 30. An arrangement comprising: the positioning mechanism of claim 1; and a piece of furniture including a flap, said flap being movable between an open position and a closed position, wherein said positioning arm is connected to said flap such that the pivoting movement of said positioning arm opens and closes said flap. 31. A positioning mechanism for driving a flap of a piece of furniture, said positioning mechanism comprising: a damping device which dampens a closing movement of the flap; a pivotably mounted positioning arm for being connected to the flap; a spring device for moving said positioning arm, said spring device including a spring-loaded setting member; and a transmission mechanism connected between said positioning arm and said spring device, said transmission mechanism converting a movement of said spring-loaded setting member into a pivoting movement of said positioning arm, wherein said transmission mechanism includes a pivotable lever connected to said spring device, wherein said spring device acts on said pivotable lever at a bearing point, wherein said transmission mechanism includes at least one adjustment device to alter the transmission ratio between the movement of said spring-loaded setting member and the pivoting movement of said positioning arm, wherein said at least one adjustment device adjusts a distance between the bearing point and an axis of rotation of said pivotable lever, wherein said damping device is formed separately from said spring device, and wherein said positioning arm includes a projection which engages said damping device to dampen a closing movement of the flap.
