Problems solved by technology

The disadvantage of this solution is the complex design and the fact that during coupling the locking hook sometimes does not engage with the form-fitting recess of the energy absorbing element and in the event of a collision the locking hook must first be displaced without absorbing energy until its Engages with form-fit recesses

Embodiment Construction

[0040] Figure 1 to Figure 4 The design of a displaceable steering column 1 for a motor vehicle according to the invention is shown. A steering shaft 3 is rotatably mounted in the actuating unit 2 . The actuating unit 2 is displaceable in the axial direction 5 of the steering shaft 3 and in the present case also in the vertical direction 6 relative to the holding unit 4 fixed to the vehicle body. The actuating unit 2 is accommodated displaceably in the axial direction in an outer sleeve 200 , wherein the outer sleeve can be attached to a vehicle, not shown, via a front bracket 400 . During displacement of the actuating unit 2 in the vertical direction 6, the front bracket 400 is elastically deformed to allow pivoting. Alternatively, a pivot axis may also be provided between the front bracket and the outer sleeve 200 .

[0041] The actuating unit 2 can be fixed relative to the holding unit 4 by means of a clamping device 7 . The clamping device 7 basically comprises a clamp...

Abstract

A displaceable steering column for motor vehicles may include an actuating unit in which a steering shaft is rotatably mounted. The actuating unit may be displaceable relative to a holding unit in the axial direction of the steering shaft, and optionally in the vertical direction, and can be clamped by means of a clamping device so that the actuating unit is fixed in an non-displaceable manner when the motor vehicle is operating normally. The steering column may also include an energy absorption device disposed between the actuating unit and the holding unit, which in the event of a vehicle crash absorbs at least part of the energy applied to the steering column by material deformation of an energy absorber. The energy absorption device may have a central portion on which an energy absorber is disposed and is engaged with the actuating unit. The central portion may be connected to a clamping portion that can be clamped by the clamping device.

Description

technical field [0001] The invention relates to a displaceable steering column for a motor vehicle, the steering column having an actuating unit in which the steering shaft is rotatably mounted, wherein the actuating unit can be positioned relative to a The holding unit is displaced in the axial direction of the steering shaft and can be clamped by the clamping device, so that when the motor vehicle is in normal operation, the actuating unit is fixed in a non-displaceable manner relative to the holding unit and the steering column has energy An absorption device, the energy absorption device is arranged between the actuation unit and the holding unit. [0002] The problem solved by using a steering column of this type with an energy absorption device is to absorb the energy applied to the steering column by the driver in a controlled manner in the event of a frontal collision of the vehicle. Background technique [0003] A steering column with an energy absorption device is...
