A system for unlocking a key cylinderless automobile vehicle door includes a portable object having an identifier and a circuit for interrogating the object. The circuit powers the object and interrogates the object when it is outside the vehicle. The interrogating circuit supplies a signal authorizing unlocking of the door as a function of the identifier. A standby power supply, which is separate from the main power supply of the vehicle, also powers the circuit and the object. As a result, the vehicle door does not require a key cylinder while still ensuring unlocking even if the main power supply of the vehicle fails.

A vehicle door is assembled by immobilizing a cable drum with a wedge and then coupling the wedged drum to a drive member. A cable is wound onto the drum either before or after the positioning of the wedge. The A drive member is then coupled to the wedged drum. After coupling, the drive member is fixed to the vehicle door. The window guide structure can also be inserted between the inner panel and an outer panel of the vehicle door. The wedge can be removed from the window guide structure, or alternately, the wedge can be fixed to the window guide structure. Alternately, the method further includes the steps of placing the cable in deflection pulleys before the steps of positioning the wedge and winding the cable. The drive member is pivotally mounted to the inner panel about an axis offset relative to the rotational axis of the drum, and the cable is tensioned by pivoting the drive member about the offset axis. The drive member is then fixed to the inner panel of the vehicle door. Essentially, a pre-assembled intermediate window drive is created that facilitates mounting to the vehicle door.

Attaching a cable drum and drive to a vehicle door

A vehicle door has a stop that can move between an urging position, in which it maintains a constant distance between a lower part of the door and the vehicle body when the door is closed, and a retracted position in which the stop does not maintain this constant distance between the lower part of the door and the vehicle body when the door is closed. The stop improves contact between the vehicle window surround and the vehicle body while the vehicle is moving, and can be retracted to make it easier to close the door.
