A steering column fastening arrangement for motor vehicles with an energy-absorbing deformation element which is arranged between a steering bracket retained fixed at the body and a tubular protective steering member. The deformation element consists of a metallic plate rigidly connected with a U-shaped member of the tubular protective steering member while the plate includes slot-like deformation sections that are arranged corresponding with elongated apertures of the U-shaped member. The tubular protective steering member is retained displaceable in case of a crash with respect to the steering bracket by way of the displacement bolts extending through the deformation sections and guided in the elongated apertures and, on the other hand, the tubular protective steering member is fixedly connected with the steering bracket. The plate of the deformation element consists of a plastically deformable metallic material and has a thickness, width and length of the deformation sections matched in a defined manner to the requisite deformation behavior.
A steering column fastening arrangement for a motor vehicle, comprising an energy-absorbing deformation means which is arranged between a steering bracket retained at a relatively fixed vehicle part and a tubular protective steering member, the deformation means including an approximately U-shaped member secured to the tubular protective steering member and a plate securely connected with the U-shaped member, said plate being provided with slot-like deformation sections which are arranged to cover corresponding elongated apertures in the U-shaped member, displacement bolt means guided in said apertures and extending through openings in the deformation sections, and said displacement bolt means retaining the tubular protective steering member at the steering bracket and causing tearing of said deformation sections of said plate for energy absorbing purposes.
