An adjustable steering column includes a steering spindle (), a shell unit () bearing the steering spindle (), a console unit (), stationary on the chassis, with at least one side wall (), which extends bilaterally along the shell unit () and supports the shell unit (). The steering column also includes a securement device, which can be opened and closed, in the opened state of which the shell unit () is adjustable relative to the console unit () at least in one adjustment direction, and which has a tension bolt () penetrating openings in the shell unit () and in the at least one side wall (). At least for one adjustment direction at least one tilting part () is provided acting in this adjustment direction, wherein in a torsion entailed in a deformation of the steering column of at least the segment, located in the proximity of the side wall (), of the shell unit () relative to the side wall (), an entrainment of the tilting part () takes place and clamping edges () and clamping faces () come to engage one another, whereby the displaceability of the tilting part () in this adjustment direction is inhibited.

A locking device of a steering column adjustable in at least one adjustment direction () comprises at least one locking part () associated with the adjustment direction () or one of the adjustment directions, at least one counterlocking part () associated with this adjustment direction () and an openable and closable tensioning arrangement, in the opened state of which first and second toothings () of locking parts () are spaced apart from first and second countertoothings () of the counterlocking part (), and in the closed state of which the locking part () and the counterlocking part () engage each other's teeth. The planes () of the tips of teeth () of the first and second toothings () or first and second countertoothings () are disposed in a V shape relative to one another and between the teeth () of the first and second toothing () or the first and second countertoothing () is present an offset (v) in the adjustment direction (), which is a fraction of the distance (a) between successive teeth (to).

A steering shaft for a steering system of a motor vehicle including an outer tubular member, and an inner tubular member extending into the outer member and secured therein against axial and/or radial displacement relative to the outer member, with the two tubular members being axially displaceable relative to each other in case of a collision, and with one of the tubular members having tear-off strips with bent-over front ends having bent-over sections engaging the other tubular member, each of the tear-off strips being formed by two spaced flutes of the one tubular member, the flutes also defining weakness locations.
