A support assembly for a collapsible automobile shade such as a pleated or folding screen which can be selectively moved between a collapsed position for storage and an open position for placement in a vehicle window. The support assembly consists of one or more arcuate compressible members which extends beyond the perimeter of the pleated or folding screen. Each of the arcuate compressible members is resiliently compressible, for the purpose of conforming to an edge or perimeter of an automobile window in which the shade is installed, while maintaining the screen in an open position, thereby supplying an expansive force to hold the shade in place in the open position.
