  • Video Screen Assembly For Vehicle
    Publication number: 20100244505
    Abstract: A screen apparatus includes a screen assembly and structure. The structure defines a cavity having an opening to a vehicle passenger compartment. The screen assembly includes a frame and a video screen mounted with respect to the frame. The screen assembly is selectively movable between a retracted position in which the screen is inside the cavity and concealed from view, and a deployed position in which the screen is outside the cavity and visible from the passenger compartment. The screen apparatus is configured such that the movement of the screen assembly between the retracted and deployed positions is restricted to substantially linear translation.
