Abstract
A substantially rectangular case having an open end is removably secured to a vertical post which forms part of the frame surrounding a vehicle windshield. A substantially opaque shade is formed from a series of hexagonal cells which are collapsible to that the shade can be folded into a compact shape within the case. One edge of the shade is secured to the interior of the case, and the other edge of the shade is attached to a cover plate which encloses the open end of the case when the shade is folded. The shade is opened to an expanded position by drawing the cover plate across the windshield so that the shade extends through the open end of the case. The cover plate is removably attached to a post on the opposite end of the windshield, and maintains the shade in a position to block sunlight from entering the windshield.
