The invention relates to an anti-withdrawal device for preventing a key from being withdrawn from an ignition starter switch of an automobile, comprising a blocking device which is coupled with a switch contact of a transmission. The spring-loaded blocking pin of said blocking device can be actuated electromagnetically. The blocking device acts on a detent pawl which is fixed on a rotor of the ignition starter switch and which prevents the ignition starter switch from twisting into a position in which the key can be withdrawn; depending on the position of the transmission. Said blocking device and said ignition starter switch are introduced into a steering-column switch housing that is integral with the casing tube, whereupon the blocking device locks mechanically and is electrically coupled with connection contacts of the ignition starter switch through terminal contacts, said ignition starter switch being connected by a printed circuit board in the steering-column switch housing to an electrical supply system.
Locking arrangement for preventing a key (1) from being pulled out of an ignition starting switch (2) of a motor vehicle, with a locking mechanism (3) that is coupled to a switching contact of the transmission, wherein the spring-loaded locking pin (25) of said locking mechanism can be electromagnetically actuated, and wherein the locking mechanism acts upon a detent pawl (5) that is fixed on a rotor (4) of the ignition starting switch (2) and prevents the ignition starting switch (2) from being turned into a position in which the key (1) can be pulled out depending on the gear position of the transmission, characterized by the fact that the locking mechanism (3) and the ignition starting switch (2) are respectively inserted into separate openings (6, 7) of a steering column switch housing (10) that is rigidly arranged on the steering column jacket, wherein the locking mechanism (3) is mechanically interlocked with the steering column switch housing (10) after being inserted therein and electrically connected to contacts (45) of the ignition starting switch (2) via terminal contacts (21), and wherein the ignition starting switch is connected to an on-board network via a printed circuit board (41) arranged in the steering column switch housing (10).
Locking arrangement according to claim 6 [sic], characterized by the fact that the modular housing (17) contains a taper (37) in the region of the ignition starting switch (2), with the opening (38) for the catch (32) being arranged in the region of the taper.
Locking arrangement according to claims 6 and 7, characterized by the fact that the catch (32) is essentially realized right-angled, with one limb (35) protruding over the taper (37) of the modular housing (17) and acting upon a locking surface (34) of the detent pawl (5) in the locked position, and with the locking pin (25) engaging behind the other limb (36).
