Steering column unit has energy absorbing element wound in or out under impact while spacing between its ends, and number of windings, remain same

摘要

The steering column unit has a jacket tube (1, 2) fixed to the body work, with the steering spindle in it, and an energy absorbing element (6) with at least one winding round a carrier axis (7). Under impact, the energy absorbing element is wound in or out, while the spacing between its ends (8) and the number of its windings remain the same.
