Claim:
1. An actuating drive for moving a flap of an item of furniture, the actuating drive comprising: an actuating portion; at least one actuating arm pivotally mounted about a pivoting axis for moving the flap; a spring device for applying a force onto the actuating arm; a transmission mechanism for transmitting a force of the spring device onto the actuating arm in a closing direction and, after exceeding a dead-center position, for transmitting a force of the spring device onto the actuating arm in an opening direction; an adjusting device for adjusting a position of the actuating portion of the actuating drive in or along a guide; wherein the actuating drive includes a coupling device which couples the spring device, the pivoting axis of the actuating arm, and the actuating portion to one another; wherein the actuating portion, the actuating arm, and the spring device are configured such that, by adjusting the actuating portion in or along the guide, a position of the dead-center of the actuating arm and a force of the spring device acting towards the opening direction onto the actuating arm can be variably adjusted so that, upon an increase of the force acting towards the opening direction, a pivoting angle of the actuating arm, at which the position of the dead center lies, can be reduced; wherein the coupling device includes at least one lever pivotally mounted about a hinge axis, the guide being arranged or formed on the lever.
