Abstract
Abstract A steering lock for vehicles, especially for motor vehicles, with a locking mechanism mechanically locking the steering as a function of the position of the ignition key and with a switch disconnecting at least a part of the power supply; a further shifting member is thereby provided in the lock housing which carries out a positively controlled stroke movement during the rotation of the ignition key; the shifting member transmits its stroke movement to a plunger of a switch which plunger is located substantially in the axis of the lock cylinder.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
182 words
A steering lock for vehicles which includes a lock housing means, a lock cylinder means, a locking means mechanically locking the steering in dependence on the position of an ignition key, and a switch means disconnecting at least a part of the power supply, characterized in that a shifting means is provided in the lock housing means which is operable to carry out a positively controlled stroke movement during rotation of the ignition key, such shifting means transmitting its stroke movement to a plunger disposed substantially in the axis of rotation of the lock cylinder means of a further switch means, and in that a slide means initiating the mechanical locking means includes a shifting means a locking cam with an abutment surface, said locking cam being operable to be displaced in the axial direction of the lock cylinder means against the force of a spring means by the ignition key during rotation of the latter, said abutment surface transferring the plunger with an inserted ignition key during the movement of the slide means onto a lug projecting from the slide means.
Claim 2
Dependent Claim
