Abstract: My invention realtes to an automobile shading device which includes a pair of extendable channels pivotally joined at their respective inner ends to a 45 degree center portion. As a result, the channels can open and close in a horizontal fashion.The device can be removably attached to a window by suction cup located on the outside of the center portion and by velcro between the channels and the dashboard. Each channel includes an arm and a plurality of pleats. Each arm is pivotally joined to the channel at its inner end, and it opens and closes in a perpendicularly circular fashion, thus, when open unfolding the pleats in an angular shape covering the entire window. The top and bottom pleats are attached to the arm and the channel respectively by two-sided tape.When the pleats are unfolded the angular shape is obtained by a uniformally asymmetrical cutting method in a zig-zag fashion.
