Abstract
A system for modulatable absorption of energy from an automobile vehicle steering column comprises a steering shaft mounted in a body-tube connected to a support assembly fixed to the chassis of the vehicle. The system for modulatable absorption of energy comprises a required number of windings with a particular section which are connected to a retaining pin device and to an anchor pin device. The anchor pin device comprises a holding rod which is moved along its axis by an electric actuator to select the number of windings concerned in the event of an impact.
