A motor vehicle has a motorized steering lock including a bolt which locks the steering column by engaging in a recess in the steering shaft in the column. The bolt is actuated by an internally threaded slider which is carried on an externally threaded drive rod, and which cooperates with abutment surfaces formed on the bolt so as to displace the latter between its locking and unlocking positions. Besides its threaded portion, and in extension of the latter, the drive rod has a portion of reduced diameter such that, when the drive rod is rotated, the slider can slide axially along the portion of the drive rod having the reduced diameter, to a position in which its internal thread is out of mesh with the external thread of the drive rod.

Motorized locking device for a motor vehicle, such as a steering lock,

An electrical antitheft system for a motor vehicle inhibits the power supply to the ignition circuit of the vehicle, by preventing the engine from starting so long as the motor that actuates a blocking member of the antitheft system has not reached the unlocked position. The logic functions for controlling locking and unlocking of the system are obtained through a wired and protected logic system that connects the power supply terminals of the motor of the antitheft system to the poles of the battery through a pair of switches.

Electrical antitheft system for motor vehicle

An electrical anti-theft security system for a motor vehicle includes an anti-theft security switch for controlling starting of the engine of the vehicle and for the supply of power to various electrical circuits of the vehicle. This anti-theft switch comprises a key interruptor and a multiple position control interruptor for controlling, in sequence, the power supply to various electrical circuits of the vehicle, including those for the ignition and the starter. The system also includes interruptors for the power supply of the electric motor of the anti-theft system, together with an immobilizing device for preventing the supply of power to at least one electrical circuit of the vehicle when the anti-theft system is not in its unlocked condition.
