ABSTRACT:
An energy absorbing steering assembly employs an elongate tubular adapter sleeve, including breakaway bolts and a bracket for mounting the sleeve on the underside of an instrument panel and at least one annular, radial sleeve flange extending inward from the side walls of the adapter sleeve, forming a reduction of the inner diameter of the adapter sleeve to a first preselected size, an elongate steering column slidably retained coaxially within the adapter sleeve, the steering column, including an annular, radial column flange extending outward from the side walls of the column, the flange being slightly smaller than the inner diameter of the adapter sleeve, a steering shaft mounted for rotation within the steering column, and elastically deformable plastic foam molded in situ to fill the cavities between the sleeve and the steering column.
