A door latch assembly for an automotive vehicle door includes a gearless cinch actuator. The cinch actuator includes an extensible housing member connected to a threaded rod by a nut. The extensible housing member is also connected to a cable for cinching the door. A motor rotates the threaded rod, which moves the extensible housing member between rest and cinched positions. The motor is connected to the threaded rod without the use of gears. An anti-friction agent, such as a combination of a PTFE-containing coating and PTFE-containing grease, is applied between the nut and the threaded rod. The materials and anti-friction agent used at the interface of the threaded rod and nut together provide a friction coefficient () of about 0.045 or less.

A method for actuating a motor vehicle lock and a locking device for a motor vehicle includes an actuating lever, a lock and a Bowden cable arranged between the actuating lever and the lock, the lock can be actuated by means of the actuating lever and with the aid of the Bowden cable, and a functional unit arranged on the Bowden cable and comprising an electric drive.

A swing type power door lock actuator includes a housing having mounted therein a drive unit, which includes a motor, a transmission unit, which includes a screw shaft connected to the motor and a transmission seat threaded onto the screw shaft, and a swing unit, which includes a sector gear meshed with the transmission seat and a swing arm connected to the sector gear. When the motor is started, the screw shaft is driven to move the transmission seat, causing the sector gear to bias the swing arm between a locking position and an unlocking position.

A vehicle door lock assembly includes a housing, a first locking assembly, a second locking assembly, a driving module and a micro switch. The first locking assembly includes an inner handle, an outer handle and a first lock tongue. The inner handle and the outer handle are disposed on the housing and respectively control the first lock tongue to move. The second locking assembly includes a second lock and a second lock tongue including a first segment and a second segment slidably connected with each other. The second lock includes a mandrel having an assembling portion. The driving module includes a motor assembled with the mandrel, and the second segment is moved when the motor drives the mandrel to rotate. The micro switch includes an inductive element, and the assembling portion has an inductive portion.

A lock assembly comprises a housing, a handle, and a latch plunger operably connected with the handle. An exterior key lock and interior lock knob have a locked and unlocked position. A lock cam is rotatably and operably connected with the key lock and interior lock knob for rotation therewith. A crank arm of the lock cam is operatively coupled with a deadbolt lock movably mounted in the housing for shifting between a locked position and an unlocked position. The deadbolt lock is also operably coupled with a motor, wherein a motor cam clutch is operably coupled with the motor and operably interposed between the lock cam and the motor, wherein the motor cam clutch allows rotation of the lock cam between the locked and unlocked positions without rotating the motor cam clutch or a motor shaft of the motor.

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.

Provided is a door latch comprising a frame piece and door piece. The frame piece may include a lever comprising a lever connector; an actuator comprising an actuator connector; a cylinder comprising an arm; and a catch configured to be moved by the lever connector, the actuator connector and the arm. The door piece may include a bolt configured to laterally slide between the frame piece and the door piece, thereby transitioning the door latch between an unlatched position and a latched position.

A latch system for capturing a striker, the latch system comprising an actuator, a position sensor, or a combination thereof is disclosed. The latch system includes a latch having a latch cam and a trigger; an actuator having a connector and a motor; and a sensor assembly having a sensing arm and a sensor. The latch cam of the latch is configured to capture the striker when in a closed position. The latch cam is retained in the closed position when the trigger of the latch is in the locked position. The trigger of the latch is moved from an unlocked position toward the locked position by the connector of the actuator when it is moved by the motor from the unlocking position toward the locking position. The sensing arm contacts the striker when the striker is captured by the latch system. The sensor is deactivated when the sensing arm is in one of the latched position or the unlatched position and activated when the sensing arm is in the other one of the latched position or the unlatched position.

A locking mechanism of a door leaf of a motor vehicle includes a latch, an electric actuator, and a transmission arrangement. The latch includes a pawl and a bolt configured to cooperate in such a manner to allow the locking or unlocking of the door leaf. The transmission arrangement is configured to transmit a movement of the electric actuator to the bolt in order to displace the bolt of the latch between an unlocking position in which the bolt is released from the pawl and a locking position in which the bolt is blocked by the pawl. The transmission arrangement includes a downstream transmission member configured to transmit a movement to the bolt, an upstream transmission member configured to transmit a movement of the actuator to the downstream transmission member; and a blocking member movable relative to the downstream transmission member and/or the upstream transmission member.

A motor vehicle lock for a flap of a motor vehicle. The motor vehicle lock is equipped with a lock catch for engaging with a closing part in a holding manner and a pawl which is paired with the lock catch and which locks an opening of the lock catch in the lowered position and releases the lock catch in a raised position, wherein the motor vehicle lock has an electric closing drive and a control assembly, wherein the control assembly actuates the closing drive in a closing routine so as to move the lock catch in the closing direction from a starting position. The control assembly actuates the closing drive in the closing routine so as to move the lock catch from the starting position into a delay position in order to carry out a delay action and then move the lock catch into the main closing position.
