Abstract

A steering column arrangement includes a steering spindle, which rotates about its longitudinal axis and serves to transfer a torque, generated by a steering wheel, to a steering gear, and a blocking device, which prevents the rotational motion of the steering spindle, especially in the event of a collision. The blocking device includes a stator, which is stationary in relation to the rotational motion of the steering spindle, and against which a blocking element is mounted in a relatively moveable manner. To prevent, in a reliable manner, an undesired twisting of the steering wheel, especially in the event of a collision, the blocking element is moveable into a locked position in a radial direction toward the steering spindle.
