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.

[ What is claimed is:] [1.]1. A vehicle door latch assembly comprising;a support housing,a ratchet pivotally mounted to said support housing and moveable between a latched position and an unlatched position,a pawl mounted to said support housing and having first and second ends with said pawl moveable between a blocking position wherein said first end abuts said ratchet to secure said ratchet in said latched position and a release position wherein said first end disengages said ratchet to permit said ratchet to pivot toward said unlatched position, anda release mechanism mounted to said support housing for selectively moving said pawl into said release position,a locking mechanism pivotally mounted to said support housing,a slider rotatably mounted to said locking mechanism to slidably move relative to said release mechanism and be selectively coupled between said second end of said pawl and said release mechanism, said slider slidably moveable between an engaged position aligned with said release mechanism for coupling said pawl to said release mechanism wherein movement of said release mechanism moves said pawl to said release position, and a disengaged position spaced from said release mechanism for uncoupling said pawl from said release mechanism wherein said pawl remains in said blocking position during said movement of said release mechanism to retain said ratchet in said latched position,an outside release lever and an inside release lever each pivotally mounted to said support housing and selectively engageable with said release mechanism for moving said release mechanism to release said ratchet, andan interior locking segment pivotally mounted to said support housing and interconnecting one of said outside and inside release levers to said locking mechanism.
