摘要

The device has drive arm (2) with one end connected via a shifting joint (22,31) to a lifting rail (5) for connection to a window pane, a toothed segment (6) connected to the drive arm and with toothing (29) and a base plate on which the toothed segment and the drive arm are pivotably mounted. The toothing of the toothed segment engages a drive pinion (8) on the base plate. A control arm (4) connects the lifting rail via rotary joints to the drive arm or to a guide arm (3) coupled to the drive arm to control a pane retraction curve.
