Abstract: A device that is used for the automatic release, without any manual effort, of the steering system in a motor vehicle comprising electric power steering and a locking mechanism which acts on the steering column or on another part of the steering system. A controller, which is connected to an electric assist motor, receives signals from at least one vehicle status and/or initiating event detector and controls the motor in order to rotate the steering column or move another part of the steering system until the torque or stress on the locking mechanism is cancelled or reduced to almost zero, thereby enabling said mechanism to be released. The control of the motor is automatically interrupted at the end of a pre-determined period of time if the mechanism has not been released.

Abstract: Engagement parts 52c of the locking device for a steering shaft are formed on a side face of a driven gear of a reduction gear mechanism which is fastened to a steering shaft 2. Since a locking part 6a is arranged near the reduction gear mechanism, elements related to a locking function can be removed from the key cylinder of the engine key, so that the key cylinder of the engine key can be downsized, or can be arranged in another position. Consequently, even in a state where a reduction gear mechanism, a steering assist motor and the like are arranged in the middle of the steering shaft, a longer stroke of the impact absorbing mechanism in comparison with conventional mechanisms can be ensured, utilizing a decrease in length of the downsized or reduced key cylinder in the axial direction of the steering shaft 2.

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.

Degrees of freedom in design of an outer shape of a column cover are thereby increased.

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.

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.
