ABSTRACT:
An overhead sliding door and foldable interior panel assembly for an airplane is disclosed. The assembly is particularly adapted for commercial airliners having a low ceiling and limited overhead space for stowage of the door above the cabin ceiling. The assembly includes a set of foldable cabin panels that operate to cover the overhead ceiling opening when the door is closed. As the door is opened by sliding upwardly along tracks through the ceiling opening, the foldable panels are engaged by the door and swung upwardly and inwardly with the door into the overhead space above the ceiling. Conversely, the foldable panels are brought into place to cover the ceiling opening as the door is brought downwardly to its closed position in the doorway. The door and the foldable panels are adapted to occupy a minimum of space in the overhead stowage compartment to thereby accommodate control cables, ducting and various other items in the overhead compartment. In the preferred embodiment, the door includes an integral escape slide container that is adapted to form a presentable closure member in the ceiling opening when the door is raised to the overhead stowed position, such that the ceiling opening is effectively closed with the door in the closed position as well as with the door in the open position.
