  • Patent number: 8226121
    Abstract: A steering column arrangement for motor vehicles with a vehicle-side console, on which an outer tube of a steering column carrying a steering shaft is attached in a releasable manner by means of a clamping device. The clamping device comprises at least one clamping wedge arrangement by which an increased holding force of the clamping device can be achieved during an axial displacement of the outer tube caused by an accident.

  • Publication number: 20080196525
    Abstract: A stop device is provided for a spindle drive which consists of a threaded spindle and a spindle nut with a stop. The stop device includes a limit stop and also a faceplate arranged between the stop of the spindle nut and the limit stop. The limit stop and the stop of the spindle nut are offset in relation to one another and are able to act upon the faceplate such that a bending moment can be applied to the faceplate when the threaded spindle and spindle nut of the spindle drive are in a limit stop position relative to one another.

  • Publication number: 20080191455
    Abstract: A safety steering column (1) is provided for a motor vehicle, which has a telescopic steering spindle (2) with an upper spindle part (3) which is near to the steering wheel and a lower spindle part (4) which is remote from the steering wheel, and is rotatably mounted in a jacket tube (5). The jacket tube (5) is of telescopic design and has an upper tube part (6) which is near to the steering wheel and a lower tube part (7) which is remote from the steering wheel, the lower tube part (7) being mounted so as to be pivotable about a first axis (10) on a bracket (9) which can be arranged fixed to the vehicle. In addition, an adjustment device which serves to vertically adjust the safety steering column (1) and has an actuating element (12) which is mounted so as to be pivotable about a second axis (14) is provided.

  • Publication number: 20070127982
    Abstract: A device for the detachable and pivotable connection of at least two components and a method for mounting the device are provided. The device includes a bolt on a first component that engages through a through-opening in a second component. The through-opening has a centering section into which a centering bushing is plugged. The centering bushing is pressed onto the centering section in order to set a defined frictional torque between the first and second components with a predefined axial force. To secure the axial position of the centering bushing, a locking element is provided, which is plugged onto the bolt and has a receptacle for the bolt. Both the circumferential surface of the bolt and the internal surface of the receptacle are provided, in at least one axial section, with a profile for forming a circular wedge connection through a relative rotational movement between the bolt and the receptacle.

  • Patent number: 6811185
    Abstract: A steering column for a motor vehicle has a steering shaft rotatably mounted in a tubular jacket. The tubular jacket is secured on two rails extending substantially in an axial direction and fixed on the bodywork. The tubular jacket is guided between the rails in the event of an axial displacement in case of a crash. At least one rail is assigned at least one deformation element which is secured at least at one end on the rail and is plastically deformable, with absorption of energy, in the event of an axial displacement of the tubular jacket in a manner such that it is deformed by rolling friction via deflection structure fixedly disposed on the tubular jacket.

  • Patent number: 6695349
    Abstract: A positional adjustment apparatus is provided for a steering column of a motor vehicle. A tubular jacket is fixed on two rails disposed substantially opposite one another, the rails extending in an axial direction of the tubular jacket and having slots extending in the axial direction for longitudinal adjustment of the steering column. Clamping bolts are provided that are guided through the slots in the rails and extend substantially in a radial direction away from the tubular jacket. At least one clamping bolt passes through a rail for vertical adjustment. Longitudinal and vertical adjustments are secured and released by means of an operating lever. The securing and releasing of the longitudinal and vertical adjustments takes place via a cam disc actuatable by the operating lever.
