A vehicle door latch assembly is moveable between an unlocked condition, a locked condition and a double locked condition. The door latch assembly has a support housing with a cover having a projecting block. A cam is rotatably mounted to the cover and includes an integral notch defining a pair of stops for selective engagement with the block. A rocker is movably mounted to the cover for selectively engaging at least one of the stops of the notch within the cam. A first controller rotates the cam into selective engagement with the block and the rocker for defining the unlocked condition and the locked condition, respectively, of the door lock. A second controller rotates the rocker to release the rocker from one of the stops of the notch to allow further rotation of the cam from the locked condition to the double locked condition.

Electrically controlled actuator for a vehicle door latch assembly

A vehicle door latch assembly moveable between an unlocked condition, a locked condition and a double locked condition. The door latch assembly has a support housing with a cover having a projecting block. A ratchet is mounted to the support housing between a latched position and an unlatched position. A pawl is mounted to the support housing and is moveable between a blocking position securing the ratchet in the latched position and a release position permitting the ratchet to pivot toward the unlatched position. A release mechanism is mounted to the support housing for moving the pawl into the release position. A coupler is couples between the pawl and the release mechanism. The coupler moves between an engaged position aligned with the release mechanism and a disengaged position spaced from the release mechanism. A cam is rotatably mounted to the cover and includes an integral notch defining a pair of stops for selective engagement with the block. A transfer element is mounted to the cam and engages the coupler for transferring the rotation of the cam into the movement of the coupler. A rocker is movably mounted to the cover for selectively engaging the notch of the cam. A first controller rotates the cam and moves the transfer element between a first position wherein one of the stops engages one side of the block and the rocker continues to engage the notch with the coupler aligned with the release mechanism for defining the unlatched condition of the door lock; a second position wherein the rocker engages the other stop to prevent further rotation of the cam with the coupler disengaged with the release mechanism to define the first locked condition; and a third position wherein the other stop engages the other side of the block and the rocker is released from the notch with the coupler disengaged further from the release mechanism to define the second locked condition. A second controller rotates the rocker to release the rocker from the notch during rotation of the cam from the second position to the third position.

Vehicle door latch assembly

A power sliding door assembly for a motor vehicle comprising a door structure constructed and arranged to be mounted on a motor vehicle for movement between closed and opened positions and a drive assembly mounted on the door structure. The drive assembly includes a rotatable gear engageable with a gear track provided on the vehicle. The rotatable gear is drivable in a one direction to effect movement of the door towards the opened position and drivable in an opposite direction to effect movement of the door structure towards the closed position. A drive shaft is coupled with the drive assembly and is constructed and arranged to rotatably drive the rotatable gear. A reversible motor is mounted on said door structure and is energizable to drive the drive shaft in a first direction to enable the drive shaft to drive the rotatable gear in the one direction, and energizable to drive the drive shaft in a second direction opposite the first direction to enable the drive shaft to drive the rotatable gear in the opposite direction. A clutch assembly is provided that is constructed and arranged to selectively couple the reversible motor with the drive shaft, so that the reversible motor is coupled to the drive shaft when energized to rotate the drive shaft in either of the first and second directions, and so that the reversible motor is de-coupled from the drive shaft to prevent back-driving of the motor when the door structure is manually moved between the opened and closed positions.
