Abstract
A steering column may include an outer casing unit in which an inner casing tube that rotatably mounts a steering shaft is received such that the inner casing tube is displaceable and fixable in an axial direction. An energy absorption device operatively disposed between the casing tube and the casing unit may absorb at least some energy in a crash event where the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may include a deformation strip fastened to but spaced apart from the casing tube, fixed in a radial direction by a spacer on the casing tube, to which deformation strip a deformation slide that is connected to the casing unit is disposed. The deformation slide may encompass and jam outer narrow sides of the deformation strip such that the deformation slide deforms the deformation strip in a crash event.
