An opening and closing device of a vehicle sliding door includes: a fully closed latch mechanism; a fully opened latch mechanism; a power releaser; a power closer; a canceler; a lock mechanism; and a relay control mechanism that includes an inner handle. The lock mechanism, the power releaser, and the canceler are disposed in the fully closed latch mechanism. The relay control mechanism includes a handle lever configured to, when a door opening operation is performed on the inner handle, rotate in a first direction to unlatch the fully closed latch mechanism and activate the cancel mechanism, and when a door closing operation is performed on the inner handle, rotate in a second direction to unlatch the fully opened latch mechanism. The inner handle is pivotally supported by the handle case of the relay control mechanism so as to be rotatable in two directions.

The invention relates to a motor vehicle door lock which is equipped with a locking mechanism (1, 2) consisting of essentially a rotary latch (1) and a pawl (2), in addition to an actuating lever chain (4) and a locking unit (5, 6). Said motor vehicle door lock also comprises a security device (8, 9, 10) which can optionally set the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning state/functioning state. According to the invention, said security device (8, 9, 10) is designed as a retrofitted module (8, 9, 10) which can be connected, according to requirements, to a base module (1-6 and 11), said module surrounding the largest part of the locking mechanism (1, 2), the actuating lever chain (4) and the locking unit (5, 6).

An automobile door latch device includes: a mesh mechanism; a body; a base; and an operation mechanism disposed on the base, the operation mechanism including: an outside lever configured to receive an operating force of an outside handle to perform open actuation; a first open lever configured to perform open actuation in conjunction with open actuation of the outside lever; a locking/unlocking mechanism; a second open lever configured to perform open actuation in conjunction with open actuation of the first open lever output from the locking/unlocking mechanism; and a fully open release lever configured to perform open actuation in conjunction with open actuation of the first open lever, wherein the fully open release lever is connected to an operating force transmission member configured to transmit the open actuation of the fully open release lever to a fully opening latch device for holding the slide door in a fully open position.

A safety exit assist system and a method therefor are provided. The system includes a plurality of child lock latches configured to be respectively located in left and right doors of a vehicle and execute child lock or child lock release and a controller configured to control the plurality of child lock latches and instruct the plurality of child lock latches to execute the child lock if receiving a proximity warning signal relative to a rear of the vehicle from a blind spot detection (BSD) device.

A power child lock system for a vehicle includes a power actuator, a wheel gear which is rotated by the power actuator, a child lock link which is moved by the wheel gear, a child lock lever which is moved by the child lock link, an inside lever which is connected to an inside handle assembly through a cable, a release lever which is mechanically connected to a door latch mechanism, and an indicator lever which is rotatable by the movement of the child lock link. The indicator lever is mounted to close a mounting hole of an inner panel.

A door latch device is provided which has a childproof locking mechanism of which a childproof lever is pivotally supported by a support shaft. The childproof lever of the childproof locking mechanism is pivotally supported on a casing by the support shaft extending in a transverse direction of a vehicle. This mechanism shifting between a childproof unlock state, in which a door opening operation by an inside handle is transmitted to an engagement mechanism, and a childproof lock state, in which this opening operation is not transmitted, and a manual operation part is formed at an end portion of the childproof lever in a longitudinal direction of a vehicle perpendicular to the support shaft such that this manual operation part passes through a cover member and projects backward.

A door latch device having a motor cover for covering a motor and connection parts thereof, wherein the motor cover in a size for covering the motor from a vehicle interior side is formed to a switch member housed in a casing, connection parts of the motor are respectively connected to conductive members of the switch member on a vehicle-exterior-side side face of the motor cover, and the motor 44 and the connection parts thereof are covered with the motor cover.

A vehicle door opening and closing apparatus includes: an input lever configured to rotate when door opening operation is performed on an inside door handle arranged inside a vehicle; and an output lever rotatably arranged on a base plate. By transmission of rotation of the input lever to the output lever when the input lever rotates along with the door opening operation on the inside door handle, a latch unit provided between a vehicle body and a door performs release operation to allow opening movement of the door with respect to the vehicle body. A sub plate is arranged on the base plate in a form of covering the baseplate, an input support shaft for supporting the inside door handle is rotatably arranged on the sub plate, and the input lever is arranged on the input support shaft so as to integrally rotate with the input support shaft.

In an embodiment, a latch includes a ratchet and pawl. A lock includes a link pivotable between unlocked and locked positions wherein a release lever operates the pawl, and the lever disconnects from the pawl respectively. A cam rotates between unlocking and locking positions wherein the link can move to the unlocked position, and the link pivots to the locked position respectively. An override member rotates between actuatable and non-actuatable positions wherein the lever can engage the override member to unlock the cam, and the lever disconnects from the override member respectively. The lock is positionable in an unlocked state wherein the link is unlocked, a locked state wherein the link is locked, the cam is in the locking position and the override member is actuatable, and a second locked state wherein the link is locked, the cam is in the locking position and the override member is non-actuatable.
