Patent ID: 12012141

Abstract:
A steering column may include a casing tube in which a steering spindle is rotatably mounted, a guide unit that receives the casing unit so as to be telescopically adjustable in a direction of a longitudinal axis, and an electromotor adjustment drive that is arranged between the casing tube and the guide unit. An inner bearing face of the guide unit surrounds an outer casing surface of the casing tube and includes a slot extending longitudinally with a slot width between mutually opposing slot edges. A preload device engages the slot edges and is configured to apply a tightening force to reduce the slot width to preload the bearing face together with the casing surface. A clamping body cooperates with the slot edges via a deflection device that converts a reduction of slot width into a radial clamping movement of the clamping body for radial preloading the outer casing surface.
