An axially adjustable steering column assembly includes an upper jacket. The steering column assembly also includes a lower jacket, wherein the upper jacket is received within the lower jacket and is telescopingly adjustable therein, the lower jacket defining a pair of slots extending in an axial direction of the lower jacket. The steering column assembly further includes a column mounting bracket, wherein the lower jacket translates and rotates relative to the column mounting bracket. The steering column assembly yet further includes a pair of bushings positioned within the pair of slots. The steering column assembly also includes a geared rack operatively coupled to one of the pair of bushings, the geared rack correspondingly rotatable with the lower jacket. The steering column assembly further includes a sensor in operative contact with the geared rack to detect the axial position of the axially adjustable steering column assembly.

An energy absorption device for a vehicle steering column comprising a metal band and an adjustable deformation unit through which the metal band extends. The deformation unit is a rotatable hollow roller having a first contact surface inside the hollow roller that is separated from an outer contact surface by an outlet slot. The metal band passes through an inlet slot into the interior of the roller, and then through the outlet slot leaves the roller, in a manner that that said metal band is entirely deformed along an S-shaped curve.
