Abstract

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.
