Abstract
An adjustable steering column may include a casing tube that rotatably supports a steering spindle, a holding part that has two lateral cheeks between which the casing tube is positioned, and an electromechanical fixing device. In a release position of the fixing device, the casing tube may be adjustable relative to the holding part. In a fixing position, a set position of the casing tube may be fixed relative to the holding part. The fixing device may include a clamping bolt that passes through the lateral cheeks and is rotatable about its axis by an electric motor positioned in a housing as the fixing device is opened and closed, a cam mechanism, and a support bearing. The lateral cheeks and the casing tube may be positioned between the cam mechanism and the support bearing. A first cam disk of the cam mechanism may rotate with the clamping bolt, and a second cam disk may be guided on the clamping bolt so as to be axially movable in the housing. The housing may be mounted in a floating manner on the second cam disk.
