An electromechanical extending device for extending window panes (2), lifting roofs or the like openable structures in motor vehicles, which can be fitted at any point in the interior space of the vehicle in the vicinity of the window, even subsequently, and can be operated from the driver's seat independently of the location at which the device is fixed, comprises a push rod (14) which is operatively connected by way of a toothed drive (17) to the output shaft (15) of an electrically operated geared motor (16), The drive unit (3) and the push rod (14) are preassembled in a housing (10) which is fixable as an independent unit to the vehicle. A reduction gear (25, 26) with self-locking properties is positioned in the drive train which also includes a worm (34). The embodiment shown has a toothed arcuate push rod (14). In another embodiment a crank driven by the motor is articulated to another member which in turn is connected to the window. <IMAGE> |
