  • Publication number: 20200189643
    Abstract: A steering column may include a steering spindle that is surrounded by a casing tube and is connected to a steering wheel, a guide clamp in which the casing tube is guided displaceably along a longitudinal axis of the steering spindle. The guide clamp may be mounted pivotably about a pivot axis in a holding part that is connectable to a chassis of the motor vehicle. The position of the casing tube may be adjustable relative to the holding part, and a blocking device may be arranged between the casing tube and the holding part. The blocking device may comprise a threaded rod engaged with a spindle nut. The spindle nut may be mounted in a rolling bearing. Rolling bodies of the rolling bearing may be at least partially surrounded by a magnetorheological fluid, and the blocking device may comprise an electromagnet.

  • Patent number: 10532762
    Abstract: A steering column for a motor vehicle may include a steering column tube in which a steering spindle is mounted rotatably about a longitudinal axis. The steering column tube is fastened to a carrier connected to a vehicle chassis so that in normal operation the steering column tube is retained non-displaceably on the carrier, but is displaceable along the longitudinal axis in a crash event where a force that acts on the steering spindle exceeds a threshold value. An energy-absorption device may comprise a bending element that is connected to the carrier and the steering column tube and may be deformed in a crash event as a result of the longitudinal displacement of the steering column tube, thereby absorbing part of the energy of the steering column tube. The bending element may be at least partially surrounded by an insertion body, which prevents the binding element from contacting adjacent structural elements and deforms together with the bending element in a crash event.

  • Patent number: 10040472
    Abstract: A steering column for a motor vehicle may comprise a steering column jacket with a jacket surface having a retaining segment. The retaining segment may at least partially surround a bearing for rotatably mounting a steering spindle about an axis of rotation. The retaining segment may have at least one tab that secures the bearing in the steering column jacket in a direction of the axis of rotation. The tab may be connected to the retaining segment of the steering column jacket along a bending edge. The bending edge may form a projection angle of at maximum 45° with a projected axis of rotation. The free end of the tab is bent around the bending edge towards the axis of rotation.

  • Patent number: 9969421
    Abstract: An energy absorption device for a steering column for a motor vehicle may include a bending bracket for energy absorption in a crash event. The bending bracket may comprise a first fastening element and a second fastening element, with the first fastening element being displaceable relative to the second fastening element if, in a crash event, the bending bracket is deformed along a guide track delimited by a start and an end. The energy absorption device may further include one or more collision elements arranged on the guide track. An example collision element may interact with the first fastening element or an element on a retaining part that is secured to the first fastening element such that the collision element, the first fastening element, and/or the element on the retaining part are deformed and absorb additional energy.

  • Patent number: 8894097
    Abstract: An adjustable steering column for a motor vehicle has at least two components and at least one locking device. The components can be adjusted in the position thereof relative to each other along an adjustment path in an open position of the locking device and are locked in the position thereof relative to each other in a closed position of the locking device. A stop element is arranged at least a first of the components such that the stop element limits the adjustment path and can be detached from the first of the components when a force value is exceeded. The adjustable steering column has a tool which can be inserted between the stop element and the first of the components in order to detach the stop element.

  • Patent number: 8882147
    Abstract: A steering column includes a steering spindle mounted rotatably about the steering-spindle longitudinal axis thereof, and a bracket unit fixed to the motor vehicle. The casing unit is held on the bracket unit so as to be displaceable in at least one direction parallel to and/or transversely with respect to the steering-spindle longitudinal axis and can be locked in differing positions by a locking mechanism. The locking mechanism has at least one locking element which is mounted moveably, preferably rotatably. In at least one locking position of the locking element, the casing unit is locked in the position thereof in the bracket unit and, in at least one release position of the locking element, the casing unit can be displaced relative to the bracket unit in at least one of the directions parallel to and/or transversely with respect to the steering-spindle longitudinal axis.

  • Patent number: 8689659
    Abstract: A steering column for a motor vehicle includes a first and a second part, which in the event of a vehicle crash can be displaced relative to each other in a displacement direction. At least one absorption element acts between the two parts for absorbing energy during the mutual displacement of the two parts, and at least one shift unit, which includes a shift component that can be shifted between a passive and an active shift position. The amount of the energy absorbed during the mutual displacement of the two parts differs in the passive and the active shift position of the shift component.

  • Patent number: 8474869
    Abstract: A steering column for a motor vehicle includes a casing unit, which rotatably supports a steering shaft about the longitudinal axis thereof, and a retaining part. The casing unit is held in a fixed manner relative to said retaining part up to a threshold value of a force acting on the casing unit in a parallel manner to the longitudinal axis of the steering shaft in the direction of the front of the vehicle. When the threshold value is exceeded, the casing unit is movably held in a parallel manner to the longitudinal axis in the direction of the front of the vehicle.
