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.
Claims34
An actuating device, comprising:
- an electromotive rotary drive for driving an actuating element about an axis of rotation between a first and a second end position,
- a spring for acting upon said actuating element in said first end position, wherein said electromotive actuating drive is a reversing drive and said spring action upon said actuating element is effective between said first end position and an intermediate position and is further ineffective between said intermediate position and said second end position, the intermediate position lying between said first and second end position.
The actuating device according to 6 further comprising at least one intermediate wheel functionally positioned between said drive pinion and said gearwheel, such that said pinion directly drives said at least one intermediate wheel which in turn directly drives said gearwheel.
The actuating device according to 8 further comprising at least one intermediate wheel functionally positioned between said drive pinion and said toothed quadrant, such that said pinion directly drives said at least one intermediate wheel which in turn directly drives said toothed quadrant.
The actuating device according to 27, wherein said partially open position is an intermediate position.
