The subject of the invention is a key collar for a motor vehicle door lock or the like including a key collar support plate fixedly attached on a support sheet, and a collar element supported on the collar support plate which, in operation, engages a lock catch of the motor vehicle door lock or the like. Optionally, the key collar includes an elastomer arrangement which allows the collar element to move a limited distance relative to the collar support plate in the plane of the collar support plate thereby better meeting the different requirements of normal use conditions and during a vehicle crash. In operation, the collar element of a preferred embodiment is supported on the collar support plate on two spaced bearing points, one bearing point with a trailing bridge in a manner that collar element can be swivelled around an axis which is perpendicular to collar support plate, and another bearing point with a leading bridge which can be displaced in corresponding arc-shaped crank.

A motor vehicle door lock or the like has a housing (,) or a lock bearing plate, a rotary latch (,) with a jaw (,) for a locking wedge (,) or lock bolt and a pawl (,) for locking the rotary latch (,) in a locking position which corresponds to the closed motor vehicle door. Several complementary measures are proposed which can be applied together or separately to optimise the locking elements&mdash;rotary latch (,) and pawl (,). A differentiated positioning of the rotary latch (,) and pawl (,) is particularly significant. The material, shape and/or mounting of the swivelling axis (,) of the rotary latch (,) or of the swivelling axis (,) of the pawl (,) are designed for normal operation conditions. However, in the event of tearing up forces which are considerably higher than the normal operation conditions (crash), the rotary latch (,) or pawl (,) can be displaced in such a way that a substantial proportion of the tearing up forces can be absorbed by the supporting area of a recess (,) which contains the rotary latch (,) or of a recess (,) which contains the pawl (,).
