A steering column assembly for a vehicle, in particular a motor vehicle, provides that an absorption part extends into a reduction part through a passage, which has a smaller cross-section than an end portion of the absorption part having the form of a rod, tube or wire. By a relative movement between the reduction part and the absorption part the end portion is pulled through the passage and plastically deformed. In such a way, an energy absorption device is formed.

Steering column assembly

A steering column assembly for a motor vehicle, having a vehicle-fixed mounting dement and a sleeve element which is received within the mounting element and is mounted for displacement in the axial direction in the mounting element for adjustment of the steering column assembly, includes an energy absorption device having two absorption elements, a locking element for locking a steering wheel, and a coupling device. The locking element has an open position, in which the steering wheel is adjustable and a coupling element is movable in the axial direction, and a closed position, in which an absorption dement is firmly coupled to the mounting element. The coupling device has a coupled position and an uncoupled position, both absorption elements being firmly connected to each other in the coupled position. During normal operation of the motor vehicle, the locking element is in the closed position and the coupling device is in the coupled position.
