    摘要: A window lift for a motor vehicle contains a functional support for at least one guide rail, which slidably guides a rail slider for retaining a vehicle window, and a cable drive device. The cable drive device has an actuating drive and a cable drive housing, into which a cable drum, which can be coupled to the actuating drive and can be rotated about an axis of rotation, is or can be received, around which cable drum a pull cable is or can be wrapped. The cable drive housing has a bottom plate and a number of cylindrical wall elements for receiving the cable drum. The functional support has, at the periphery of a through-opening for the coupling of the cable drum to the actuating drive, a joining contour for establishing a form-locking connection to the cable drum housing when the cable drum is inserted therein.

    摘要: A method of operating a motor vehicle locking system including an electric drive for providing a locking function, a central battery of the motor vehicle supplies electrical energy to the electric drive during normal operation, an auxiliary energy supply supplies electrical energy to the central battery and is arranged in a closure arrangement of the motor vehicle, the closure element is configured to assume an open and a closed position. Access to the auxiliary energy supply is blocked by the closure element in the closed position and cleared in the open position. The central battery is monitored by a control unit to check whether an emergency operation criterion is satisfied. The closure element is locked in the closed position by means of a lock unit, and when the emergency operation criterion is satisfied, the lock unit is actuated by the control unit to unlock the closure element.
