Abstract: A sunshade consisting of one or more panels for all type windows and particularly side and rear vehicle windows. The sunshades made of a tear resistant corrugated base material with die cuts that provide a plurality of louver apertures. Die cut notches may be provided for joining and interlocking one panel to another permitting the sunshade to be made wider or narrower. The panels may also include integral stiffening members that double as mounting support legs so that the panels stiffly traverse large areas. The aperture flaps may be individually moved to any desirable angle that prevents sun glare and blaze from penetrating the windows of a moving vehicle, but without obstructing the ambient daylight or overall vision of the occupant. When parked, the flaps may be pressed back into the die cut aperture cavities so as to provide opaque panels for full sun blockage.

Abstract: A sunshade consisting of one or more panels for all type windows and particularly side and rear vehicle windows. The sunshade is made of a tear resistant corrugated board material with die cuts that provide a plurality of louver apertures. Die cut notches may be provided for joining and interlocking one panel to the another permitting the sunshade to be made wider or narrower. The panels may also include integral stiffening members that double as mounting support legs so that the panels stiffly traverse large areas.
