The invention relates to a closing system for a door, in particular a side door of a motor vehicle, comprising a door lock, an inner door handle for opening the door lock, an outer door handle for opening the door lock, an actuator unit and a control mechanism, which is driven by the actuator unit, for implementing different closing states of the closing system.

A vehicle latch, including: an override mechanism, the override mechanism having: a central door lock sector; a double lock sector; a double lock link, the double lock link operably coupling the central door lock sector to the double lock sector; a key cylinder; and a key cylinder link, the key cylinder link operably coupling the key cylinder to the central door lock sector.

An actuation device for a lock of a motor vehicle, said actuation device allowing a plurality of functions without requiring a large number of parts and/or a complex and/or voluminous structure. This is achieved in that the actuation device according to the claims for opening a locking mechanism of a motor vehicle lock comprises an anti-theft device, a central locking device, and a childproof lock device. A multifunction coupling lever is provided which is capable of opening a locking mechanism of a motor vehicle lock by means of an opening movement. The opening movement of the multifunction coupling lever can be prevented by the anti-theft device, the central locking device, and the childproof lock device. Thus, an actuation device is provided which is capable of performing a plurality of functions while comprising few components. Because only a few components are required, the structural complexity can be low.

A motor-driven door latch for a vehicle includes a catch part which is caught on a striker mounted on the vehicle. A door locking and releasing part includes a main motor and applies torque to the catch part through the main motor to allow the catch part to be locked to or released from the striker. A motor-driven emergency door releasing part is provided with an auxiliary motor and is contacted with the door locking and releasing part. An inside emergency operating lever is connected with an inside handle installed at the door for the vehicle. An outside emergency operating lever is connected with an outside handle installed at the door for the vehicle. A manual emergency door release part is connected with the inside emergency operating lever.

A door latch device includes a latch mechanism, an inner lever having a connection lever and an actuation lever, and a lock mechanism switching between unlocked and locked state. The lock mechanism includes a connection member capable of transmitting operation of the connection lever to the actuation lever, a first rotating lever rotated by a motor to first and second working positions, a second rotating lever rotatable to a first rotation position where the connection member is moved to an unlock position and a second rotation position where the connection member is moved to a lock position, a connection spring connecting the first rotating lever and the second rotating lever while allowing relative rotation of them, and a holding spring having a biasing force stronger than a biasing force of the connection spring and holds the first rotating lever at the first and second working positions.

The object of the invention is a motor vehicle door lock that is equipped with a lock housing (4), also with a lock cylinder nut (3) supported in the lock housing (4), and at least one locking element (9) that can be acted upon by the lock cylinder nut (3) via a positioning element (8). According to the invention, the lock cylinder nut (3) has a connected eccentric element (6). Said eccentric element (6) engages in an eccentric mounting (7) of positioning element (8) in order to displace it.
