Abstract
A motor vehicle steering column comprises a steering shaft mounted in a body-tube connected via a support assembly to the chassis of the vehicle, the support assembly comprising a mobile support, a fixed support attached to the chassis of the vehicle and a double winding mounted on a member rotating on a fixed shaft. The double winding has a central portion mounted on the mobile support connected to the body tube so that in the event of an impact the mobile support pushes the double winding and unwinds it to absorb energy.
