Abstract: A solar radiation shield includes a flexible shade assembly mounted on an automotive vehicle sun visor to prevent solar radiation from reaching interior surfaces of the vehicle when the vehicle is left standing in the sun for a protracted time period. The shade assembly includes a rotary spindle and a flexible sheet spirally wound on the spindle so that the sheet can be manually unrolled from the spindle to span the inner surface of the vehicle windshield. During normal operation of the vehicle the flexible sheet is wound onto the spindle so that the sun visor is enabled to perform in conventional fashion.
