Anti-theft device for motor vehicles

摘要

An anti-theft device for motor vehicles which selectively disables the vehicle by interrupting the operative connection of the steering wheel to the steering column. The device includes an outer cylindrical boss which is fixed to the steering wheel and rotatably mounted on and about an inner cylindrical boss affixed to the steering column. A key actuated locking mechanism is carried by the outer boss which selectively engages the inner boss to operatively connect the steering wheel to the steering column. By unlocking the locking mechanism, this operative connection is interrupted and the vehicle cannot be controlled by the steering wheel and is thus disabled. As the disabling of the vehicle is obtained when the locking mechanism is in an unlocked position as opposed to a locked position, damaging the mechanism by the application of excessive force will not overcome its disabling effects.
