Adjustable steering column for motor vehicles, having energy absorption device

Abstract

The invention relates to an adjustable steering column (1) for motor vehicles, comprising an adjustment unit (2), in which a steering shaft (3) is rotatably mounted, wherein the adjustment unit (2) can be moved in relation to a corrosion-resistant holding unit (4) in the axial direction (5) of the steering shaft (3), and optionally also in the vertical direction (6), and can be fixedly clamped bymeans of a clamping device (7), such that the adjustment unit (2) is fastened in such a way that the adjustment unit cannot be slid in normal operation of the motor vehicle, and comprising an energy absorption device (8), which is arranged between the adjustment unit (2) and the holding unit (4) and which absorbs at least part of the energy that is input into the steering column (1) by material deformation of an energy absorber (9, 10) in the event of a vehicle crash, is improved with regard to a simple design that is economical to produce in that the energy absorption device (8) has a centralsegment (11), on which at least one energy absorber (9, 10) is arranged, which is in engagement with the adjustment unit (2), and that the central segment (11) is connected to at least one clamping segment (12, 13), which can be fixedly clamped by means of the clamping device (7).

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...

AI Technical Summary

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
