Abstract
An adjustable steering column may include a casing unit that rotatably supports a steering spindle part and that is mounted in a guide box in an axially sliding manner and can be axially adjusted by a motor drive. The motor drive has an electric motor secured to the guide box and drives an axially aligned threaded spindle that is mounted on the guide box in a rotatable and axially fixed manner and that engages into an adjustment nut. The adjustment nut is connected to the casing unit, is axially movable together with the casing unit relative to the guide box, and is mounted in a connection part secured to the casing unit to transmit axial forces to the casing unit. The adjustment nut may be guided between opposing inner guide surfaces of the connection part with clearance such that the adjustment nut is movable within the guide surfaces on a plane orthogonal to an axial direction.
