ABSTRACT:
A vehicle door latch has a latching mechanism and stiffness adjustment mechanism disposed in a housing. The housing includes a fishmouth slot for receiving a striker. The latching mechanism includes a fork bolt that moves between a latching position and an unlatching position. The fork bolt has a throat that is aligned with the throat of the housing for receiving the striker when the fork bolt is in the unlatching position and that captures the striker when the fork bolt is in the latching position. An overslam bumper has an elastomeric portion located at a rearward end of the housing slot. The elastomeric portion engages the striker and biases the striker against a surface of the throat of the fork bolt when the striker is captured. The elastomeric portion is preloaded by the stiffness adjustment mechanism that includes a flexible portion of the housing, an expandable bushing, a nut that slides in the bushing for expanding the bushing and an adjustment screw that screws into the nut. The nut is readily accessible at a surface of the vehicle door for adjusting the stiffness of the door latch.
