A closing device for a motor vehicle lock, in particular to a closing aid for a motor vehicle door lock. According to its basic design, said closing aid has a locking mechanism substantially consisting of a rotary latch and a pawl. Furthermore, an electric motor and a transmission following the electric motor are realized. The transmission operates on the rotary latch at least during a closing operation. According to the invention, for the mechanical interruption of the closing operation, the transmission has a force flux element which can be selectively engaged and disengaged.

An electric lock for a motor vehicle opening leaf includes a bolt, a pawl, a central opening lever, and an actuator with three abutment positions and capable of interacting with the central opening lever, the actuator including a driver. The driver includes a toothed driving wheel and a driven wheel. The driven wheel includes a second driving member, a motor intended for driving the actuator, a central transfer lever able to be moved by the driven wheel of the driver by the second driving member and the movement of which is capable of being transmitted to the central opening lever in order to move the pawl into its retracted angular position. One of the wheels of the driver includes a first circle-arc shaped oblong slot and the other wheel includes a first driving member extending through the first circle-arc shaped oblong slot.

A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

A power actuator for a latch of a motor vehicle closure panel has an electric motor to rotate a lead screw about an axis. A nut is disposed about the lead screw for selective translation along the lead screw. A clutch plate is configured for selective rotation about the axis when engaged with the nut, with a biasing member biasing the nut out of engagement with the clutch plate when the electric motor is de-energized. A carrier member is coupled with the nut to cause the nut to translate into engagement with the clutch plate during rotation of the lead screw, whereupon the nut and carrier member co-rotate with the clutch plate and leadscrew. A driven member is operably coupled with the clutch plate and with the latch via a cable/rod, such that the driven member maintains the latch in a cinched state when the electric motor is energized.
