Abstract
A device for a high-clearance motor vehicle is provided. Preferably, the device comprises a linear actuator, a hollow tube having a first helix and a second helix; a step arm connected at a distal end to the linear actuator such that when the linear actuator applies a linear force to the step arm, the step arm rotates. A first end portion of a distal end of the step arm inserted in the hollow tube extends through the first helix and a second end portion of the distal end of the step arm inserted in the hollow tube extends through the second helix. When the device is operated, depending on user selection, the device can serve as a vehicle step, protect the vehicle door(s), or be in a retracted position.
