Abstract: A motor drive device for moving a vehicle sliding door is provided. The device includes an electric motor, a force transmission mechanism operationally connectable to the vehicle sliding door and the electric motor to transmit a drive force provided by the motor to the sliding door, sensors at least for determining an instantaneous position of the vehicle sliding door, an electronic control unit for activating at least the motor, and a shift clutch coupled to the force transmission mechanism and couplable to the motor for load-independent coupling of the motor to the force transmission mechanism. The control unit, in the event of application of a sufficient force to the sliding door during a power-driven movement, either elevates a speed of the vehicle sliding door by elevating the transmitted drive force or decouples the force transmission mechanism and the motor with the shift clutch.

Abstract: A cable guide arrangement is provided for a power-operated vehicle sliding door, having a driven traction cable which is diverted by means of a roller system. The roller system has a holder in which there is mounted a diverting roller by means of which the traction cable, guided through the holder, is diverted. A guide channel is formed on the holder. The traction cable is guided through the guide channel to the diverting roller. The guide channel has at least one guide surface by means of which the traction cable, when it bears against said guide surface, is diverted in the direction of a tangential profile in relation to the diverting roller.
