Abstract

A projection system for projecting television images in a vehicle including a console for mounting to the roof of a vehicle with a housing in which a video projector for television signals is fixedly mounted. The console further includes a cover which is pivotally mounted to the housing at its forward end for movement between a closed position, substantially enclosing the projector, and an open position. A projection screen is movably mounted to the housing to move the screen between a substantially horizontal stored position within the cover and housing, and a substantially vertical use position when the cover is opened. The console further includes, in a preferred embodiment, light blocking panels coupled between the cover and housing for enclosing the sides of the space between the projector and screen for providing a dark environment between the projector and the surface of the screen facing the projector.
