Abstract: A window-blind for use in vehicles which includes a suction-cup for removably attaching a window-blind to a window of the vehicle and a plurality of elongated slats, each of the slats having one end pivotally connected to the suction-cup. The plurality of slats are stacked one on top of another when the window-blind is in a closed position, and are opened into a fan-shaped blind when the window-blind is in an open position. A connecting tape connects adjacent slats to each other and retains the window-blind in the fan-shape when the window-blind is in an open position. Each slat includes six apertures. The apertures are spaced approximately equi-distant from one another across the width of each slat.
