A closure latch assembly for a vehicle door includes a latch mechanism and a lock mechanism. The lock mechanism includes a lock link pivotable between unlock and lock positions, and dual cam arrangement which functions in coordination with rotation of a power lock gear to establish a first locked state where a first cam holds the lock link its lock position and a second locked state where a second cam holds the lock link in its lock position. An unlocked state is established when neither of the first and second cams engage the lock link in its unlock position.

In a vehicle door latch apparatus, a one-motion operation can be allowed. Switching element is in a double unlocked state when it is in the connected position and is in a double locked state when it is in the disconnected position. The double unlocked state enables a one-motion operation, in which switching element is linked to the release operation of first inside lever in order to switch the locking mechanism from the locked state to the unlocked state and in which the release operation of first inside lever is transmitted to second inside lever in order to open the door, and in the double locked state, switching element is not linked to the release operation of first inside lever, prevents the release operation of first inside lever from being transmitted to second inside lever and prevents the locking mechanism from being switched from the locked state to the unlocked state.

A mechanism for a double-pull type door latch is described. A return mechanism is described that includes a final lever coupled to rotate about a pivot. A position wheel is rotationally coupled to the pivot, the position wheel having a first notch and a second notch, the position wheel being rotatable in a first direction. A cam member is coupled to the position wheel, the cam member having a cam surface. A drive lever is arranged to engage the first notch and the second notch. A biasing member is arranged to apply a force on the cam surface to move the position wheel in the first direction when the drive lever is moved into the second notch.

Apparatus, systems, and methods for selectively locking and unlocking a passenger door. The apparatus includes a first shaft, having a first longitudinal centerline, and a member, connected to the first shaft. A handle is connected to the first shaft via the member, the handle being movable via rotation of the first shaft from a locked position and an unlocked position. A first protrusion extends from the handle and a latch crank is connected to the second shaft. A second protrusion extends from the latch crank and a linkage is connected between the latch crank and the member. When the handle in the locked position, the first protrusion is positioned adjacent to the second protrusion to prevent rotation of the second shaft. When the handle is in the unlocked position, the first protrusion is positioned away from the second protrusion to enable the second shaft to rotate.

A closure latch assembly for a motor vehicle closure system includes a power release mechanism and an inside handle release mechanism mechanically connected to an inside door handle. The power release mechanism is used to shift the inside handle release mechanism from a normally Disengaged operating state to an Engaged operating state. In the Disengaged state, the inside handle release mechanism is uncoupled from the latch release chain of components to prevent latch release via actuation of the inside door handle. In the Engaged state, the inside handle release mechanism is coupled for the latch release chain of components to permit latch release via actuation of the inside door handle. The power release mechanism only shifts the inside release mechanism from its Disengaged state into its Engaged state in the event of an emergency condition.

An electronic door latching assembly for a side door of a vehicle is disclosed and includes a retaining member and an actuator. The actuator is operably connected to the retaining member and moves the retaining member between a primary position and an unlatched position. The electronic door latching assembly also includes a control module in electrical communication with the actuator. The control module executes instructions to: receive as input a power signal indicating that a loss of electrical power in the vehicle is imminent. After receiving the power signal, the control module receives a door open signal indicating that a door of the vehicle is being opened. In response to receiving the door open signal, the control module commands the actuator to rotate the retaining member from the unlatched position to the primary position where the side door is unable to latch shut.
