Abstract
A steering column may include a casing unit in which a steering spindle is rotatably mounted about a longitudinal axis and which has at least three telescopically guided casing tubes that are mutually adjustable in an axial direction. One of the tubes is an external casing tube in which an intermediate casing tube is received, an internal casing tube being received in the intermediate casing tube. A locking bolt installation can releasably lock at least two of the casing tubes to one another in the direction of the longitudinal axis. The locking bolt installation can switch between an internal blocking position and an external blocking position. The intermediate casing tube in the internal blocking position is locked to the internal casing tube. The intermediate casing tube in the external locking position is locked to the external casing tube.
