  • Publication number: 20180037167
    Abstract: An adaptable load floor assembly, storage compartment, and associated control system for a vehicle. The vehicle includes a storage compartment with a load floor, a rear opening, a door for selectively closing the opening, and a platform hinged to the load floor and located within the storage compartment when the door is closed. In use and when the door is open, the platform is pivotable from a retracted position in which the platform partially obstructs the opening and a deployed position in which the platform extends out of the opening to provide an extension to the load floor. The platform is operated automatically by an actuator and the free end of the platform is supported by a tether. The vehicle includes a control unit for controlling the movement of the platform in accordance with safety criteria to avoid damage.
