摘要

The device has a drive driven by electric motors (1) from a starting position to an open position. A back movable door unit is conveyed into a pre-programmable opening angle position with a desired value by the drive using a control device such that the control device has a recognition device for recognition of the momentary actual opening angle positions of the door unit during an opening movement. The control device controls the opening movement of the door unit using the drive depending on a target actual value comparison of the opening angle positions.
