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.

A door latch apparatus that is mounted on a vehicle door and that achieves at low cost a structure that is for ensuring operational reliability of an open lever. The door latch apparatus includes a cap formed by resin material and including a cylindrical shape, the cap being arranged in an inserted manner at an attachment shaft extended in a form of a shaft in a predetermined direction, an elastic spring member that elastically biases a pawl from a non restriction position towards a restriction position, and a coming-off prevention mechanism that, by making part of the elastic spring member to engage with the cap, prevents the cap from coming off from the attachment shaft.

A latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on/off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on/off positions to the other.

A remote control device for a vehicle includes an interior handle coupling lever that rotates in accordance with manipulation of an interior manipulating handle, an exterior handle coupling lever that rotates in accordance with manipulation of an exterior manipulating handle, and a switch device. The switch device includes an interior manipulation detector for detecting rotation of the interior manipulating handle, an exterior manipulation detector for detecting rotation of the exterior manipulating handle, and wiring members each having a detector connection terminal and an external connection terminal connected to the interior manipulation detector or the exterior manipulation detector. The remote control device further includes a body and a housing. The body accommodates the interior manipulation detector, the exterior manipulation detector, and the wiring members and has a connector portion enclosing all of the exterior connection terminals for the wiring members. The housing covers the body.

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.

The invention relates to a motor vehicle door lock comprising a locking mechanism consisting essentially of a rotary latch and a pawl, further comprising an actuation lever mechanism (2a, 2b) that acts on the pawl, and a child safety device (3) that includes a child safety lever (4) to which the force of a spring (5) is applied. According to the invention, the child safety lever (4) and the spring (5) are designed as a subassembly (4, 5).

A vehicle door operation device includes an inside handle, a full open unlocking lever for transmitting a closing operation of the inside handle to a full open door latch device, and a full closure unlocking lever for transmitting an opening operation of the inside handle to a full closure door latch device. The inside handle has first and projecting portions, and when the inside handle rotates in a first direction by the closing operation, the first projecting portion is brought into abutment with the full open unlocking lever to enable the full open unlocking lever to operate, whereas when the inside handle rotates in a second direction by the opening operation, the second projecting portion is brought into abutment with the full closure unlocking lever to enable the full closure unlocking lever to operate.

The present invention relates to a vehicle door latch system, more particularly, relates to a vehicle door latch system whose locking driving unit comprises a motor, a first gear connected to the motor, and a second gear interlocked with the first gear, wherein a connect through hole wherein a key connect is penetrating through, and two of a rotating stopping portion wherein a locking stopping portion is caught by are formed spaced apart along the circumferential direction so that a locking member is moved as the motor operates, and two of a key stopping portion are formed spaced apart along the circumferential direction so that the locking member is moved as the key connect is rotated, so that the device can be miniaturized, and at the same time, when the key connect or the motor is out of order, or when the vehicle components are frozen in winter, since they can be operated separately, therefore the locking member can be moved smoothly.

An over-center spring of a vehicle door latch device has a coil part that is loosely inserted on a spring support shaft, and a base end side spring leg part. A leading end side spring leg part elastically holds an abutting pin and is paired with the base end side spring leg part. A lock lever is provided with a slot through which the spring support shaft passes. The lock lever and the spring support shaft are disposed to be superposed on each other in an axial direction of the spring support shaft.

The aim of the invention is to provide 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 (3, 4) of a motor vehicle lock comprises an anti-theft device, a central locking device, and a childproof lock device. A multifunction coupling lever (9) is provided which is capable of opening a locking mechanism (3, 5) of a motor vehicle lock by means of an opening movement. The opening movement of the multifunction coupling lever (9) 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.
