  • Publication number: 20130269468
    Abstract: A height-adjustable safety steering column assembly includes a console installed securely on the vehicle and in which an outer jacket tube is pivotably mounted. The outer jacket tube comprising includes a steering spindle having a universal joint and an inner jacket tube, which surrounds a telescoping steering wheel-side section of the steering spindle. The pivotable connection of the outer jacket tube with the console installed securely on the vehicle is implemented by two riveted joints provided diametrically on a circumference of the jacket tube and which form a rotation axis corresponding to the universal joint axis of the steering spindle. For each of the connections formed by two rivets, the console installed securely on the vehicle has a passage leading into a passage of the outer jacket tube. A rivet closing head is seated on the jacket tube side.

  • Publication number: 20090151498
    Abstract: A steering column arrangement for motor vehicles includes a steering column designed to be changeable in terms of its inclination and/or length and a clamping system having plate packs for fixing the steering column in a specific position. The steering column arrangement is designed for increasing the frictional force in the clamping system and/or for locking the clamping system, preferably by way of form-fitting engagement, with structure that acts automatically when a threshold load, acting on the steering column in the direction of its longitudinal axis, is exceeded.

  • Patent number: 7415908
    Abstract: A clamping device includes a first clamping plate and a second clamping plate, the first clamping plate being rotatable between a released position and a clamped position in relation to the second clamping plate. The clamping device further includes a rolling body which establishes contact between the first and second clamping plates. The second clamping plate includes a clamping ramp with a contour for the rolling body so that when the clamping plates are rotated in relation to each other, the space between the clamping plates changes. The first clamping plate has a surface which forms a plane on which the rolling body rolls from the released position to the clamped position.

  • Publication number: 20080116675
    Abstract: A steering column arrangement includes a bracket which is arranged fixedly on the vehicle, a steering column which has a casing tube and a steering spindle which is mounted rotatably therein, the steering column being configured so as to be adjustable in its inclination and length, and clamping device(s) being provided for fixing the steering column. In order to increase the safety of vehicle occupants, the steering column with the clamping device(s) is connected to the bracket via a bracket slide which is mounted displaceably on the bracket, it being possible for the bracket slide to be displaced relative to the bracket only after a predetermined force which is applied to the steering column in the axial direction is exceeded, and the predetermined force being smaller than a force which may be absorbed by the clamping device(s).

  • Patent number: 7370553
    Abstract: A steering spindle arrangement having a first component remote from the steering wheel and a second component near the steering wheel, with one of the mutually facing ends of the one component dipping into the hollow end of the other component, and with the two ends being connected frictionally to each other, is disclosed. Furthermore, a method for producing the arrangement is disclosed. In order, in a simple manner, to obtain as specific a definition as possible of the absorption by the steering spindle of the deformation energy in the event of a crash while ensuring that the arrangement is durable and directly transmits the steering moment, it is provided that the walls of the two ends lie directly on each other in the form of a press fit over the region of the frictional connection.

  • Publication number: 20070164549
    Abstract: A steering column arrangement has a console arranged fixedly with respect to the vehicle and a steering column which has a steering column tube and a steering spindle mounted rotatably in the latter. The steering column is designed to be variable in its inclination and length, and a clamp for securing the steering column is provided. In order to increase the safety of the vehicle occupants, while at the same time maintaining known comfort functions, and to ensure a reliable use of the steering column arrangement, it is proposed to connect the steering column to the console by the clamp via a console slide which is mounted displaceably on the console. Furthermore, an actuation element operatively connected to the clamp is provided for releasing and locking the clamp, and the operative connection is releasable.
