Energy absorbing collapsible steering apparatus

摘要

An energy absorbing apparatus includes first and second telescopingly arranged members. A non-deformable ring is mounted on one end of one of the members and engages a plurality of projections extending from the side wall of the other member. The projections extend longitudinally along the other member and are provided in various lengths, widths, heights and numbers to provide selective force versus displacement characteristics during the telescoping collapse of the first and second members with respect to each other. Preferably, the first and second members form a steering column housing for a vehicle steering apparatus.
