Abstract: An arrangement for locking the steering shaft of a motor vehicle, includes a blocking device and a toothed ring which is arranged on the steering shaft and in which a blocking element, which is arranged so that it can be displaced from an unlocked position into a locked position, of the blocking device engages. To allow the blocking device to be attached to the steering device of the vehicle in question and exchanged in a simple manner and to ensure that the blocking device cannot be removed in the locked state of the blocking element, the blocking device, which is provided with a housing, is releasably connected to a flange, which is attached to the steering device, via an adapter part. The flange has a recess which is designed in such a manner that the adapter part, for fitting of the blocking device, can be inserted in a partial area of the recess and can then be displaced along a guide into its limit position.

Abstract: A device for electrically locking the steering shaft of a motor vehicle steering device, which comprises an electric motor with actuator connected downstream, for displacing a blocking element which is arranged so that it can be displaced from its unlocked position into its locked position, and a switching device fore activating the electric motor. To ensure that the arrangement can be of very compact design and can be fitted without major changes in vehicles produced by different manufacturers, the invention proposes that the arrangement be composed of two separate subassemblies: a locking device with a first housing, in which the electric motor with actuator connected downstream and the blocking element is arranged, and manufacturer-specific electronic switching device, which can be attached o the outside of the first housing.
