摘要： 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.
