    Abstract: 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.

    Abstract: 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.

    Abstract translation: 一种用于机动车辆的动力滑动门组件，包括门结构，其构造和布置成安装在机动车辆上以在关闭位置和打开位置之间运动，以及安装在门结构上的驱动组件。 驱动组件包括可与设置在车辆上的齿轮啮合的可旋转齿轮。 可旋转齿轮可以沿一个方向驱动，以实现门向打开位置的移动，并可沿相反方向驱动，以实现门结构朝向关闭位置的移动。 驱动轴与驱动组件联接并且构造和布置成可旋转地驱动可旋转齿轮。 可逆电动机安装在所述门结构上并且可激励以沿第一方向驱动所述驱动轴，以使得所述驱动轴能够沿所述一个方向驱动所述可旋转齿轮，并且可激励以沿与第一方向相反的第二方向驱动所述驱动轴 方向使得驱动轴能够沿相反方向驱动可旋转齿轮。 提供了一种离合器组件，其被构造和布置成选择性地将可逆电动机与驱动轴联接，使得当通电时可逆电动机联接到驱动轴，以在第一和第二方向中的任一方向上旋转驱动轴，因此 当门结构在打开和关闭位置之间手动移动时，可逆电动机从驱动轴脱耦合以防止马达的反向驱动。
