Abstract
An automotive vehicle electric door latch mechanism includes a striker, a catch, a pawl, a key actuatable lock cylinder lever, an electrically driven output gear, and a manually actuatable release lever. The catch has a striker receiving surface and a pawl engaging surface. The pawl has a pin projecting therefrom, a catch engaging surface, and a cam contacting surface, the pawl being pivotally movable from a biased, catch engaging position to a catch disengaging position. The key actuatable lock cylinder lever has a pin striking surface and is pivotally movable between a biased, neutral position and a pin striking, pawl pivoting, catch disengaging position. The electrically driven output gear has at least one cam that is electrically movable between a neutral position and a pawl contacting, pawl pivoting, catch disengaging position. The manually actuatable release lever has a pin contacting surface and is manually pivotally movable from a biased, neutral position to a pin contacting, pawl pivoting, catch disengaging position.
