Abstract
The disclosure relates to a motor vehicle steering column anti-theft device of the type including a casing in which a lock is mounted rotationally between an angular locking position in which a legitimate key can be axially introduced (conventionally from the rear towards the front) or removed, and at least one angular utilization position, in which said key cannot be extracted from the lock, said lock including a rotary projecting part forming a cam that can cooperate with a control finger carried by a bolt to control the axial movements of said bolt which can slide in said casing in an axial direction between two positions: a retracted position in which it is retracted into said basing, and a forward anti-theft position towards which it is pushed elastically and in which it projects from said casing axially via a hole in said casing and prevents a part on the steering column from rotating when said lock is in said locking position with said key extracted, wherein said bolt carries a locking finger projecting radially towards the axis of said casing and penetrating a locking recess formed in a lateral face of said projecting part when said bolt is in said forward anti-theft position, to prevent or limit movement of said bolt towards said retracted position; said locking finger is automatically pushed out of said recess during rotation of said lock from said locking position into said utilization position; and said bolt is held in said retracted position, in the presence of said key, by a mobile restraining mechanism which move to an inoperative position in which said bolt is no longer held when said key is withdrawn.
