The retractable panel is a length of flexible sheet material rolled onto a roller, with the roller driven by at least one spirator retractor. A spirator may be installed at each end of the roller, in the case of larger, longer, and/or heavier panels. Two such assemblies may be installed in a single housing, in mirror image to one another to operate in opposite directions from a single central location. Decorative and/or other illumination may be included on the roller housing, and the extension of the panels may be motor driven. The lighting and/or motor operation may be directly or remotely controlled. The retractable panel may be adapted to a number of different uses and environments, e.g., as retractable protective wall pads for installation in elevators or other close confines, as vehicle covers, as permanently installed or portable advertising or informational banners, etc.
