A sunshield device is disclosed having two (11,12) relatively movable, collapsible screen means (13,14) fabricated of material which upon relative motion between screen means operates to filter, block, scatter and reduce the intensity of solar radiation. The desired effect is achieved by using polarizing film (21,22), imprinting patterns of opaque (26) and have parent stripes or dots so that upon rotation, translation or orbital motion of one screen means relative to another screen means virtually any desired intensity of solar radiation can be achieved including a complete solar block. |
