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. Moreover, transverse webs are arranged between the teeth of the toothed ring, which webs, in the locked position of the blocking element, prevent axial displacement of the adapter part along the recess in the flange to the partial area.

Arrangement for electrically locking the steering shaft of a steering device

The invention relates to a device for locking the steering column of a motor vehicle steering mechanism, with a locking device arranged within the zone of the steering column, and with a central controller electrically connected to said locking device, whereby the locking device comprises an electrical setting member for displacing a slidably arranged locking element from its unlocking into its locking position, and a sensor for monitoring a predetermineable condition of the locking device. In order to make it possible for the condition of the locking device to be monitored by means of the sensor also while the motor vehicle is driving, without causing thereby any increase of the safety risk, the invention proposes that the sensor be connected to the central controller in such a way that if the supply voltage for the locking device is switched off, the central controller is capable of scanning and evaluating the condition of the locking device detected by the sensor.

Device for interlocking the steering column of an automotive steering mechanism

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.
