A shade assembly comprised of a frame having a central opening therethrough and a hollow, shell-like recess at one end thereof. A flexible shade member is removably received in the recess in the form of a scroll, and a pull bar coupled with one end of the shade member is used for pulling the shade member out of the recess, i.e., unscrolling or unwinding it, and into a position across the central opening of the frame. The shade member is biased so that, as the pull bar is moved toward the recess, the shade member becomes scrolled or wound in the recess. The end margins of the pull bar are removably received within a first pair of grooves on the opposed sides of the frame, and a transparent, protective pane is mounted with its side margins received within a second set of grooves on the sides of the frame adjacent to and extending longitudinally of the first set of grooves. The assembly is constructed in cartridge form so that it can be readily mounted in place as a unit at a fixed location, such as adjacent to a window of an airplane, and the assembly can be quickly removed from its mounting for replacement purposes. This invention relates to improvements in shade structures, such as window shades used in passenger compartments of airplanes and, more particularly, to an improved shade assembly which can be made and used in the form of a quick-replacement cartridge.
