Abstract
A steering column may include an inner casing tube that rotatably mounts a steering shaft, an outer casing unit in which the inner casing tube is displaceable and fixable in an axial direction, and an energy absorption device operatively disposed between the casing tube and the casing unit. The energy absorption device absorbs at least some energy in a crash event when the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may have at least two deformation strips fastened to the casing tube, and a deformation slide may be disposed on each strip. Each deformation slide may be connected to the casing unit and may encompass and jam external narrow sides of the respective deformation strip so that each deformation slide deforms the respective deformation strip when the deformation slide in a crash event is displaced in the axial direction on the deformation strip.
