Abstract
A motorized retractable step apparatus includes one or more steps that move between a retracted position and a deployed position. The step apparatus includes a drive member that spans the length of the step apparatus and rotates to retract or deploy the steps. The step apparatus uses a direct drive configuration to transfer power from an electric motor to the drive member. The step apparatus can also includes a brake coupled to the electric motor and/or extruded aluminum steps. These features simplify construction of the step apparatus and make it more reliable than conventional motorized steps.
