Abstract
An adjustable steering column includes a steering spindle (1), a shell unit (3) bearing the steering spindle (1), a console unit (4), stationary on the chassis, with at least one side wall (5), which extends bilaterally along the shell unit (3) and supports the shell unit (3). The steering column also includes a securement device, which can be opened and closed, in the opened state of which the shell unit (3) is adjustable relative to the console unit (4) at least in one adjustment direction, and which has a tension bolt (11) penetrating openings in the shell unit (3) and in the at least one side wall (5). At least for one adjustment direction at least one tilting part (26) 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 (5), of the shell unit (3) relative to the side wall (5), an entrainment of the tilting part (26) takes place and clamping edges (36) and clamping faces (35) come to engage one another, whereby the displaceability of the tilting part (26) in this adjustment direction is inhibited.
