Abstract

The present invention relates to an actuating device with an electromotive rotary drive, via which an actuating element can be driven rotatably about an axis of rotation between a first end position and a second end position and can be acted upon out of the first end position by a spring. The electromotive actuating drive includes a reversing drive and the spring action upon the actuating element is effective between the first end position and an intermediate position. The spring action is ineffective between the intermediate position and the second end position. The intermediate position lies between the first end position and the second end position.
