  • Publication number: 20200269901
    Abstract: An adjustable steering column for a motor vehicle may comprise a rotatable steering shaft that has a shaft part that can be displaced axially along its axis of rotation. The shaft part may be rotatably mounted in a jacket tube that is mounted in an axially sliding manner in a guide box held on a retaining part fixed to the vehicle body and can be displaced by means of an electric motor. The adjustable steering column is improved with respect to a small installation space of the electrical adjustment in conjunction with high strength of the steering column. A gear rack may be attached to an outer face of the jacket tube. Also, the electric motor may be fastened to the guide box and may drive a worm gear that protrudes through an opening in the guide box towards the jacket tube and meshes with the gear rack.

  • Publication number: 20170129531
    Abstract: A steering column for a motor vehicle may include a supporting unit and a displacement unit. The supporting unit may be connectable to a chassis of the motor vehicle, and the displacement unit may be displaceable relative to the supporting unit along a displacement path in a crash event. The steering column may further include an energy absorption element positioned between the supporting unit and the displacement unit. In a crash event, the energy absorption element may absorb energy over the displacement path. In some examples, the energy absorption element includes local laser solidifications that help control an energy absorption level of the energy absorption element.
