Abstract
A steering column arrangement for a motor vehicle may include a guide part for rotatably mounting a steering shaft about a longitudinal axis, a guide box that is mountable on the motor vehicle and in which the guide part is arranged displaceably along the longitudinal axis, and a clamping system that is for locking the guide part in the guide box and that is switchable between a locked state where the guide part is secured relative to the guide box and a released state where the guide part is displaceable relative to the guide box in a direction of the longitudinal axis, and first and second contact surfaces disposed between the guide box and the guide part. In the released state the first contact surface is in first frictional contact with a surface of the guide part that opposes a displacement of the guide part along the longitudinal axis relative to the guide box. In the locked state the second contact surface is in second frictional contact with a surface of the guide part wherein a frictional force designed as a holding force acts between the guide box and the guide part.
