Problems solved by technology

[0006] However, it is clear that when the driver causes further power to be supplied to the electric starter motor (while the internal combustion engine is already in operation), there is a risk of damage to the starter motor or the internal combustion engine
If the user restarts the starter motor too quickly when the internal combustion engine has not been properly started by the first start attempt, the vehicle's transmission and the various moving parts of the starter motor return to their original positions and have stopped rotating. create further risk

Embodiment Construction

[0036] In these figures, the same elements have the same reference numerals.

[0037] Figures 1 to 12An embodiment of a steering lock immobilizer 1 for a motor vehicle 1 is shown, which is designed to be assembled around a steering column. In a manner known per se, and not shown in the figures, the anti-theft device 1 comprises locking means comprising a bolt mounted for translational movement in the anti-theft body between a released position and a locked position, in which In the released position the locking bolt is designed to be arranged at a distance from the steering column, in the locked position the locking bolt is designed to lock the steering column. The bolt is activated via means of driving the bolt coupled to the cam of the anti-theft device so as to be displaced by the lock 2 . Access to the key to the lock at the front (AV) of the anti-theft device 1 is available at figure 1 see in.

[0038] if available at figure 2 As seen in , the lock 2 is fixed to th...

Abstract

The invention relates to a steering lock antitheft device for a motor vehicle. The device comprises: an antitheft body (3) intended to house a lock (2) capable of turning between a neutral position (STOP) and a start position (DEM) via an intermediate position (MARCHE), a cam (4) intended to rotate as one with the lock (2) to actuate locking means of the antitheft device (1) according to the position of the lock (2), a nonreturn means to prevent the said cam (4) from turning in the opposite direction towards the start position (DEM) once it has reached the intermediate position (MARCHE) when moving from the start position (DEM) towards the neutral position (STOP) without first of all moving via the neutral position (STOP), and is characterized in that a cam profile (5) is formed in a radial wall of the said cam (4) and in that the said antitheft device (1) further comprises a control finger (6) and a means of elastically returning. The means of elastically returning is used for the control finger (6) resisting against the action of the cam profile (5), and the cam profile (5) and the said control finger (6) work together firstly to form the nonreturn means and secondly to index the angular position of the cam (4).

Description

technical field [0001] The invention relates to a steering lock anti-theft device for a motor vehicle, comprising an anti-theft body designed to receive a lock capable of rotating through an intermediate position between a neutral position and an activated position; a cam designed to be rotationally fixed to the lock , to actuate the locking means of the anti-theft device depending on the position of the lock; and non-return means to prevent the cam once it has reached the middle when it travels from the starting position to the neutral position without first passing the neutral position. position, the cam rotates in the opposite direction towards the start position. Background technique [0002] In particular, in antitheft devices in which the lock can adopt at least three positions, namely "stop", "operate" and "start", the invention relates to a non-return device preventing said cam from After one cycle (from the "operating" position towards the "starting" position), the...
