Abstract: A clamping device may include clamping jaws that selectively clamp a steering column tube that is adjustable. A clamping pin may connect the clamping jaws. Rotation of the clamping pin in a closure direction causes the steering column tube to be clamped between the clamping jaws, and rotation of the clamping pin in an opening direction releases the clamping jaws for adjustment of the steering column tube. A damping member may be disposed on the clamping pin and connected to the clamping pin in a frictionally engaging or resilient manner. The damping member may comprise a stop tongue that protrudes radially from the clamping pin. When the clamping pin rotates in the opening direction, the stop tongue moves into abutment with the steering column tube and prevents rotation of the damping member so that the rotation of the clamping pin in the opening direction occurs counter to the friction force or resilient force and is damped.

Abstract: A latching star wheel for a steering lock of a motor vehicle may have a hollow profile with a longitudinal axis and a plurality of latching recesses that can be brought into engagement with a locking bar of the steering lock that can be moved between a locking position and an unlocking position. The latching recesses may be configured as projections. An inner surface of the latching star wheel may be configured as a contact surface that is circularly perforated in a circumferential contour. The latching recesses may extend parallel to the longitudinal axis across a full length of the latching star wheel.

Abstract: A steering column may include a casing unit with a steering spindle that is rotatable about a longitudinal axis and a bracket unit that is fixable on the motor vehicle. The casing unit may be secured to the bracket unit such that the casing unit is adjustable in at least one direction. The casing unit may be fixable in different positions by a fixing mechanism. The fixing mechanism may have a fixing element that is rotatable about a pivot axis. The casing unit may be fixed in position in or on the bracket unit in a locked position of the fixing element, and adjusted relative to the bracket unit in a released position of the fixing element. A movably mounted stop body may interact with the fixing element and, in the released position of the fixing element, is disposed in a first position where it limits adjustability of the casing unit relative to the bracket unit. In the locked position of the fixing element, the stop body may be disposed in a second position where it disengages with the casing unit.

Abstract: Steering columns for motor vehicles may comprise a supporting unit, which can be connected to the chassis of the motor vehicle, and an adjusting unit, which may be held at the supporting unit. The adjusting unit may support a steering spindle for transferring a steering motion from a steering wheel to a steerable wheel, wherein the adjusting unit can be shifted with respect to the supporting unit in the event of a crash. An energy absorption device may have a first sliding rail, which can be fixed at the adjusting unit, and a second sliding rail, which can be fixed to the supporting unit. The first and second sliding rails may be guided in contact with one another and, in a crash event, can be shifted with respect to one another in order to absorb energy.
