Abstract: A steering column locking device has an electromagnetic key interlock function that operates a solenoid to prevents a key knob from being undesirably moved to a lock position, as well as a mechanical key interlock function to conduct the key interlock function even when the solenoid malfunctions. The device includes the key knob and a plunger coupled to the key knob, so that when a user manipulates the key knob to start the vehicle, the plunger both moves axially and rotates. A cam shaft is coupled to the plunger, and a return spring is provided between the plunger and the cam shaft to bias the plunger towards the key knob. A stroke restrictor restricts a stroke of the plunger in the axial direction, and a push release functioning mechanism mechanically prevents the plunger from rotating from an accessory position to a lock position when the key interlock function fails.

Abstract: The invention relates to an electric steering lock wherein a permanent magnet (20) and two different Hall sensors (21,22) are used to recognise a locking and an unlocking position. The pole transition (23) of the magnet (20) is oriented in the direction of the lift (14).

At said end distance (10.1), the N-active sensor (21) is oriented towards the north pole and the S-active sensor (22) is oriented towards the south pole of the permanent magnet. Said end distance (38, 39) corresponds to the distance at which the magnetic flow density (30.1) of the permanent magnet (20) is at least identical to the threshold value (21.1) required to turn on (28.1, 29.

Abstract: A locking bolt for irrotationally locking a motor-vehicle steering shaft is axially movable inside a housing between locked and release positions, and is fixable in the locked position by means of a spring-loaded securing pin axially movable in the housing that cooperates with a lateral recess in the bolt. The bolt is fixed in the event a part of the housing fitted with a retaining arm retaining the securing pin against the action of its spring load is removed, thereby releasing the securing pin to fix the bolt. The securing pin is not manipulable after its release by removal of the housing part and the retaining arm because it is neither visible nor accessible through the cavity in the housing through which the retaining arm extends.

Abstract: In a steering lock device, a lock bar is disposed so as to be offset parallel to a key cylinder along a longitudinal direction of a vehicle (i.e., a central axis of the lock bar and a central axis of the key cylinder are parallel), and is disposed so as to be adjacent to the key cylinder along the central axis of the key cylinder. Further, a proximal end of the lock bar and a rear end of the key cylinder are disposed so as to overlap one another. In accordance with the steering lock device, an amount of projection from a steering column (i.e., a rectilinear distance from an outer peripheral surface of the steering column to a center of a key insertion opening of a key rotor) can be kept small. Degrees of freedom in design of an outer shape of a column cover are thereby increased.

Abstract: The invention provides a locking pin for a steering column lock assembly. The locking pin includes a dual taper defined by the first and second truncated cone portions. The first truncated cone portion narrows at a first angle and the second truncated cone portion narrows at a second angle, wherein the first and second angles are different from one another. The second angle can be less than the first angle. The dual taper of the locking pin reduces the likelihood that extreme torsion will not induce camming forces urging the locking pin out of engagement with a locking plate connected to the steering shaft.

Abstract: An electrically-driven steering lock device is provided having a lock body that, if broken while a vehicle is parked, the lock body is divided into a main body portion and a guide portion. A lock pin is inserted through a through-hole of a movable plate and fits into a fit-in hole formed in a lock stopper such that movement of the lock stopper is impeded. A locked state of a steering shaft is thereby maintained. Further, movement of the movable plate in a direction of being pulled-out also is impeded by the lock pin, and an interior of the guide portion is prevented from being exposed. Moreover, the lock pin is provided within the guide portion, and even if the guide portion is viewed from an exterior, it is difficult to learn of a mechanism and a position of the lock pin. Therefore, it is difficult to cancel a locked state. Thus an electrically-driven steering lock device is provided in which it is difficult to cancel the locked state by an illegal act, and which has a good antitheft quality.

In the lock device, due to a lock arm, which is formed integrally with a helical gear, being driven to rotate by a motor, a lock stopper and a lock bar are moved toward a steering shaft and are set in a locked state. Usually, locking is released by the lock stopper and the lock bar being moved toward a side opposite the steering shaft due to elastic urging force of a spring.

Abstract: The aim of the invention is to provide a steering column lock with improved break-up safety. To this end, a spring-loaded locking pin (30) is integrated into the peripheral cam (12), said locking pin being co-rotated when a rotor (10) pertaining to the steering column lock is rotated. In the test position (30.1) of the locking pin (30), the pin is aligned with a locking recess (38) in the housing (1) while in a working position of the motor (10) that is obtained by access authorization means, it is not. Normally, the locking pin (30) is inactive since it is maintained in a retracted position by a spring-loaded (47) feeler (40). When the rotor (10) is missing, the feeler (40), due to its spring load (27), releases the locking pin (30). If in this case the rotor (10) is in the rest position, the locking pin (30) engages in the locking recess (38) of the housing (11) and blocks rotation.
