A latch release backup system for a latch assembly of a motor-vehicle door is provided with a key cylinder configured to receive a vehicle key and which is rotatably mounted to the motor-vehicle door, and a mechanical coupling arrangement mounted within the motor-vehicle door and operable to convert a rotation of the key cylinder into actuation of an actuation group of the latch assembly for causing latch release. The key cylinder defines an electrical interface socket designed to receive the vehicle key. An electronic control unit is mounted within the motor-vehicle door and is electrically connected to the electrical interface socket to receive identification information (Id) from the vehicle key when plugged into the electrical interface socket. The mechanical coupling arrangement is normally disengaged from the actuation group of the latch assembly, and the electronic control unit is configured to control selective engagement of the mechanical coupling arrangement to the actuation group of the latch assembly based on the identification information (Id) received from the vehicle key.

A door opening and closing apparatus for a vehicle includes a transmission gear configured to be driven to rotate by a motor, a pulley arranged coaxially with the transmission gear and configured to open and close a vehicle door by moving a rope member with a rotation of the pulley, an output member arranged coaxially with the transmission gear and configured to bring a door lock to a holding state or a release state with a rotation of the output member, a first clutch housed in the pulley in a state being coaxial with the transmission gear, the first clutch selectively permitting and prohibiting a rotation transmission between the transmission gear and the pulley, and a second clutch housed in the transmission gear in a state being coaxial with the transmission gear, the second clutch selectively permitting and prohibiting a rotation transmission between the transmission gear and the output member.

A motor vehicle locking device is equipped with a coupling arrangement consisting essentially of an actuating lever and a release lever that can be coupled releasably thereto. The actuating lever and the release lever can be coupled to one another starting from an uncoupled basic position by a two-stroke actuation of the actuating lever. An accumulator lever storing the first stroke of the operating lever is additionally provided so that, during its second stroke, the operating lever can act upon the release lever that follows the accumulator lever. According to the invention, a safety lever is provided as a complement, which suppresses in its secured position a subsequent movement of the release lever during the second stroke of the actuating lever and permits said movement in its unsecured position.
