Abstract: A triggering pin is connected between the steering column cover and the ignition switch lock, or a glass bead is held between the ignition switch lock and the ignition switch lock mounting assembly, of an automobile including a steering column lock. When either the steering column cover in the area of the ignition switch lock or the ignition switch lock itself is removed, the triggering pin or bead, connected to a trigger wire, triggers a switch that removes power from a propulsion system function necessary for the driving of the vehicle. In addition, where the automobile includes a conventional security system, the triggering of the security device trips a switch to provide power to the conventional security system. Power may also be provided to a hood lock spliced onto the hood release cable that, when actuated, prevents the cable from moving.

Abstract: 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.

Abstract: A key interlocking mechanism for an automobile ensures that the automobile transmission is in the proper position when the key is removed. The mechanism includes a stopper pin protruding into the rotational path of the key motor and a solenoid valve energized when the automobile transmission is shifted out of park. When the key rotor is rotated with the solenoid valve unenergized, a cam plate within the mechanism acts to push the stopper pin up out of the rotational path of the key rotor. When the solenoid valve is energized, the stopper pin is prevented from being pushed out of the rotational path of the rotor. The key rotor is thus prevented from being rotated to a position in which the key can be removed from the rotor.

Abstract: A lock for the ignition circuit for an automobile including a Hall effect control sensor which is activated by a control magnet on the cylinder member of the lock so that when the cylinder is rotated by the key to its start position, the control sensor is activated. The activation of the control sensor provides one of several starting criteria to an ignition for starting an automobile. An anti-tampering sensor spaced from and adjacent to the control sensor has a trip level which is lower than the trip level of the control sensor so that magnetic forces induced from the exterior of the lock cannot trip the control sensor. A blocking plate is disposed between the control sensor and the anti-tampering sensor to prevent the anti-tampering sensor from being tripped by the control magnet when the cylinder member is rotated to its start position and to enable the anti-tampering sensor to be tripped first to produce a deactivation signal in response to a magnetic force induced from the exterior of the lock.

Abstract: A locking arrangement between a selector lever of a transmission and an ignition lock of a motor vehicle has a locking pawl, which is rotatably disposed in a selector lever block. The locking pawl, via a recess, form-lockingly reaches around a cam part arranged on the selector lever.

In this case, a catch hook of the locking pawl engages into the moving path of a locking cam, which is arranged on the selector-lever-side end of a flexible linkage. The catch hook acts in a blocking manner, as long as the button is operated into a first position. When the button is not operated, the ignition lock, which by way of the linkage is connected with the locking cam, can be rotated into an inoperative position, whereby the locking cam fixes the locking pawl. The button cannot then be operated because the cam part is fixed by the recess.

Abstract: A locking arrangement between an ignition lock and the selector lever of an automatic motor vehicle transmission has a locking slide arranged on the selector-lever side which, via a control ramp, displaces a locking bolt into a position blocking locking pin. This blocking position can only be achieved when the selector lever with the inoperative button is in the parking position and an ignition key has been rotated into an inoperative position. When the ignition key is pulled out, the selector lever cannot move out of the parking position, thereby preventing an accidental engaging, for example, in a neutral position.
