Longitudinal adjustable steering column e.g. steering shaft of motor car, has energy absorber device that is directly arranged in series between guide pipe and control unit in which power is flowed to fix guide pipe by control unit

摘要

The steering column (1) has servo-motor control units (4,5) to adjust and fix a guide pipe (2) relative to a jacket tube (3) along adjustable direction (6). An energy absorber device (12) has an energy absorber element that is transformable under power consumption for absorption of impact energy. The fixation of the guide pipe is carried out through the control unit by using the flow of power between the guide pipe and control unit. The energy absorber device is arranged as independent component and is directly arranged in series between the guide pipe and control unit.
