Abstract

A steering column fastening for a motor vehicle includes a deformation element between a steering bracket retained at the body and a protective tubular steering member; the deformation element consists of an energy-absorbing plate connected with a bow-shaped bracket member of the protective tubular steering member which plate includes deformation sections which are arranged corresponding with longitudinal slots of the bow-shaped bracket member and in which are guided the displacement bolts extending through the deformation sections. The energy-absorbing plates are arranged between a lower support element of the bow-shaped bracket member and upper guide elements arranged parallel thereto. The upper guide elements are supported at the steering bracket of the body and include longitudinal slots which are arranged corresponding to further longitudinal slots of the lower support element. The guide elements extend over the entire length of the plate-side deformation sections and the latter are laterally delimited by longitudinal slots.
