Abstract
A vehicle door latch has a forkbolt that moves between a latched position and an unlatch position and a detent that moves between a detent position where the detent holds the forkbolt in the latched position and a release position where the detent releases the forkbolt for movement to the unlatch position. The vehicle door latch includes a detent spring that biases the detent toward the detent position and a release mechanism that moves the detent against the bias of the detent spring to the release position to release the forkbolt. The vehicle door latch also includes an auxiliary detent spring that decelerates the movement of the detent to the detent position under the bias of the detent spring to reduce noise when the detent strikes the fork bolt. An auxiliary counter spring and an alternative auxiliary helper spring are shown.
