Abstract
A collapsible steering column for a vehicle includes an energy absorption device in the form of a wire bent into a U-shape with a member attached to an outer tube of the column engaging the base of the “U” of the wire. The free arms of the wire are contained within two apertures of a steering column adjustment block, in which the outer tube is mounted, with the base of the wire lying outside of apertures of the block. Upon vehicle crash, the outer tube moves and the member presses on the base of the wire to draw the arms of the wire out of the two apertures and into a third aperture intermediate of the two. The wire is given different cross sectional profiles to meet specified energy absorption criteria.
