Abstract
A steering column may include an inner casing tube in which a steering spindle is mounted rotatably about a longitudinal axis, an outer casing unit in which the inner casing tube is retained, and a motorized adjustment drive for longitudinal relative movement between the outer casing unit and the inner casing tube. The inner casing tube and the outer casing unit are coupled via an energy absorption device that has at least two energy absorption elements and a coupling device. A first energy absorption element can be coupled or uncoupled between the inner casing tube and the outer casing unit via the coupling device, which energy absorption element can be plastically deformed in the coupled state with relative displacement in the longitudinal direction of the inner casing tube and the outer casing unit. The coupling device has a coupling element that is movable between the uncoupled and the coupled state. The coupling element can be brought into operative engagement with a coupling piece that is connected to the first energy absorption element.
