Abstract

A step assembly includes an upper housing adapted to be fixedly secured to the motor vehicle. A step is movable relative to the upper housing between a stowed position and a deployed position. A single arm is pivotal with respect to the upper housing and pivotal with respect to the step in order to form a three-bar linkage for moving the step between the stowed and deployed positions.
