Abstract
A steering column for a motor vehicle, having an inner casing tube which rotatably supports a steering shaft, and an outer casing unit in which the inner casing tube is received movably in the axial direction and is fixable, also having an energy absorption device which is arranged functionally between the casing tube and the casing unit, in which a portion of the energy occurring in the event of a crash can be absorbed when the casing tube is moved telescopically relative to the casing unit, wherein the energy absorption device comprises at least one deformation strip, which is pulled through a brake element and thereby deformed, is improved according to the invention in order to reduce the installation space of the overall steering column in that the deformation strip is fastened on a carrier plate, which in turn is fastened to the casing tube and projects in the axial direction beyond the casing tube.
