Abstract

An extendible and retractable step assembly for mounting on vehicles. The assembly includes a mount which is fixed to either side of the vehicle. An extendible subassembly includes a step mounted on a movable swing arm in a preferred parallelogram linkage. The pivot axes of the arms are inclined causing the step to be moved downward and outward into an extended position. Cable and motor operators are shown to provide automatic operation when the vehicle door is operated. A safety release is used on the cable operator to allow vehicle door operation even if the step assembly becomes jammed.
