Abstract: A steering column is disclosed for a motor vehicle, including an actuating unit, in which a steering spindle is rotatably mounted about a longitudinal axis. The actuating unit includes a casing unit which has at least three casing tubes which are arranged so as to be axially telescopable relative to one another. One of the casing tubes forms an outer casing tube in which at least one intermediate casing tube, in which an inner casing tube is accommodated, is accommodated. Rolling bodies are arranged between the casing tubes such that they are able to roll in the axial direction. First rolling bodies are arranged between the outer casing tube and the intermediate casing tube, and second rolling bodies are arranged between the intermediate casing tube and the inner casing tube, the first rolling bodies being arranged offset in the circumferential direction relative to the second rolling bodies.

Abstract: A steering column includes a jacket tube with a clamping section with a slot extending longitudinally. A clamping collar has transversely opposed legs are interconnected via an arcuate section between which the clamping section of the jacket tube is at least partially accommodated. An actuating unit is arranged in the jacket tube, with a steering spindle rotatably mounted therein around the longitudinal axis. A clamp fixes the actuating unit longitudinally relative to the jacket tube and in a release position unclamps the clamping collar and frees the actuating unit longitudinally and presses the legs toward each other transversely to the longitudinal axis in the fixing position. Driver elements are arranged on the jacket tube in opposite edge regions of the slot, and the legs include contact elements which in the fixing position can be pressed against the outer sides of the driver elements.

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 vehicle steering column includes a support unit and by which an actuator unit is held in which a steering spindle is mounted to rotate about a longitudinal axis.

Abstract: A method and a device generate haptic feedback for a vehicle driver, the haptic feedback being generated by applying an additional torque, which alternates about an average total steering torque, to a steering grip of a vehicle by way of an actuator. When the present haptic feedback is recognized and/or simultaneously when haptic feedback occurs, the actuator is actuated such that the magnitude of the average total steering torque is increased by a compensation torque.

Abstract: An adjustment drive for a steering column adjustable by motor includes a threaded spindle with an axis. The threaded spindle engages in a spindle nut, a drive unit and a gear wheel connected to the spindle nut or the threaded spindle for rotation therewith, which is driveable to rotate about the axis by the drive unit and rotatably mounted about the axis in a bearing housing in an arrangement between two outer bearing rings axially supported at the bearing housing. The outer bearing rings each have, on their facing sides, a circumferential outer bearing face coaxial to the axis, the outer bearing face in each case lying opposite a bearing face on the end side at the gear wheel. At least one outer bearing ring is axially resiliently supported at the bearing housing by an elastic preloading element that axially braces the two outer bearing rings together.

Abstract: A motor-adjustable steering column including a supporting unit which is connectable to a vehicle body and by which an actuating unit is held which includes a steering spindle mounted in a casing unit to be rotatable about a longitudinal axis. The casing unit has an outer casing tube, in which an inner casing tube is accommodated to be axially displaceable telescopically in the direction of the longitudinal axis. An actuating drive is connected to the inner casing tube and the outer casing tube by which the inner casing tube may be displaced axially in and out relative to the outer casing tube. A feature arranged between the outer casing tube and the inner casing tube generates a frictional force between outer casing tube and inner casing tube with regard to relative displacement which is adjustable between a release position and at least one friction position.

Abstract: A steering column may include an adjustment unit with a steering spindle mounted rotatably about its longitudinal axis in a casing tube, a support unit in which the adjustment unit is mounted so as to be adjustable along the longitudinal axis, and a stop device with a movably mounted stop element positionable in a blocking position and a release position. In the blocking position the stop element limits the adjustment travel of the adjustment unit relative to the support unit. In the release position, the stop element allows adjustability in the direction of the longitudinal axis beyond the adjustment travel limited in the blocking position. The stop device has an actuation body that has an inert mass, is actively connected to the stop element, and is mounted movably relative to the support unit. In a crash event, the mass inertia of the actuation body causes it to interact with the stop element to move the stop element from the blocking position into the release position.

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.

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.
