ABSTRACT:
A latch mechanism includes a chassis and a latch bolt movably mounted on the chassis. The chassis includes an abutment, and the latch bolt is moveable between an open position in which the latch bolt can receive a striker of a vehicle, a closed position at which the striker is capable of being retained by the latch bolt, and an over-travel position. The latch mechanism includes a buffer having a displacing element and an engagement portion. The buffer is capable of operably acting between the abutment and the latch bolt to absorb over-travel of the latch bolt. The displacing element is capable of moving frictionally against the engagement portion during over-travel to generate a frictional force to absorb over-travel energy of the latch bolt.
