Abstract

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.
