Abstract
A steering column with an inner casing tube rotatably mounts a steering shaft. An outer casing unit is connected to a vehicle chassis and the inner casing tube is displaceably received therein and configured to be axially fixable. An energy absorption device is operatively disposed between the casing tube and the casing unit and in which part of the energy arising in the event of a crash is absorbed when the casing tube is telescopically displaced in relation to the casing unit. The energy absorption device is configured to adapt the absorbed energy to the circumstances of the crash event.
