A method of deactivating a secondary lock feature of a vehicle includes sensing a movement of an interior door handle, and determining a status of the secondary lock feature to ascertain whether the secondary lock feature is active. The method includes starting a timer to measure an elapsed time since sensing the movement of the interior door handle, sensing an environmental condition of an interior passenger compartment of the vehicle with a sensor, and setting an unlock delay time based on the environmental condition. When the secondary lock feature is disposed in an active state and the elapsed time period is greater than or equal to the unlock delay time, the method includes automatically generating a control signal to thereby deactivate the secondary lock feature.

The invention relates to a motor vehicle door lock (1) which comprises a locking mechanism having a rotary latch and at least one pawl, and a first actuating lever (8), the locking mechanism being at least indirectly unlockable by means of the actuating lever (8), and the locking mechanism further having a locking device (21). The actuating lever (8) can be disengaged from the locking mechanism by means of the locking device (21). An additional motor vehicle door lock (2) is provided, and said vehicle door lock (2) can be actuated by means of the actuating lever (8). The actuating lever chain to the additional motor vehicle lock (2) can be disengaged by means of the locking device (21).

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.

A power child lock operating device may include a rotating drive device; a first operating lever which receives the torque of the rotating drive device to be rotated; a second operating lever connected to the first operating lever to be moved together; a third operating lever connected to a door catch to lock or unlock the door catch; an inside handle lever connected to an inside handle disposed at a door of a vehicle to be moved together; a fourth operating lever selectively connecting the inside handle lever and the third operating lever; and an elastic member pressurizing to the fourth operating lever so that the third operating lever may be connected to the inside handle lever, improving the operation reliability the power child lock device.

An override mechanism for a cinching latch assembly includes a claw rotatable between open and closed positions, the claw spring biased toward the opened position to allow opening of a latch. Also included is a cinch drive link rotatable between an override and non-override positions, the cinch drive link in operative contact with the claw in the non-override position and disengaged from the claw in the override position, wherein operative contact between the claw and the cinch drive link biases the cinch drive link toward the override position. Further included is a guide surface. Yet further included is a cinch override lever defining an opening, the bearing of the cinch drive link disposed within the opening and moveable within the opening. Also included is a cinch override pawl rotatable between an engaged condition and a disengaged condition, the engaged condition locking the cinch override lever.
