A vehicle door lock having a forked latch includes a knuckle joint mechanism with a link thereof articulated at one end to the lock housing and at the other end to the other member of the knuckle (namely a catch member) which, in the closed position of the door lock, holds said forked latch firmly around a corresponding pin of the lock keeper. The knuckle joint mechanism is spring urged to an “over center”position in which the point of engagement of said pin and said latch member has overshot a position of alignment with a line through the articulation axes of said link. Advantageously the keeper pin is at least in part formed of shock absorbing material.

In a vehicle door lock comprising a housing adapted to be secured to a vehicle door; a forked latch member mounted movably within said housing and having first and second prongs; and comprising a keeper catch element which is adapted to be mounted on a vehicle body and is constituted by a pin coming into engagement with the fork of the Latch, the improvement wherein (a) said housing includes a knuckle joint mechanism arranged to cooperate with said forked latch member for locking the latch member in position; (b) said knuckle joint mechanism includes a link one end of which is articulated to the casing, and a catch member articulated to the other end of said link; and (c) a spring carried by said housing biases the knuckle joint mechanism towards a position corresponding to overshooting of the point of engagement of the catch member on said forked latch member beyond a position of alignment with the axes of the two articulations of said link.
