<p>A striker (33) for a vehicle door locking mechanism comprises a head (59) providing a base (65) and sloping sides (74,81) symmetrically tapered in at least two directions towards an apex (79) directed to enter a latch housing (43). The striker has a shank (73) for mounting the striker on the vehicle body. The latch housing (43) comprises a body (45) and a movable female portion (51) fitting telescopically inside the body (45). The female portion (51) is shaped to receive the striker head (59), and slides into the housing body (45) only when the striker head (59) is completely seated within the female portion (51). The latch mechanism has a ratchet (77) which engages the striker (33) and a pawl (83) which engages one leg (77a) of the ratchet (77) when the door is lightly closed and another leg (77b) of the ratchet (77) when the door is fully closed. A resilient block (87), which restricts movement of the female portion (51) into the housing body (45), is compressed as the striker head (45) moves into the housing (43), to allow the pawl (83) to engage the second leg (77b) of the ratchet (77) and then expands to ensure that the pawl (83) properly engages the ratchet (77). Several alternative embodiments of striker, tapered in one or two directions, are described.</p> |
