Abstract

An automatic electrically operated visor or sun blocker system for a vehicle includes a sun blocker, such as a visor (81), that is automatically positioned laterally across the vehicle windshield (1) to selected azimuth (.psi.) directions, depending upon the relative azimuth direction of the sun and is automatically extended downward to selected elevation (.theta.) directions, depending upon the relative elevation direction of the sun, as required to block the sun so that it does not strike the vehicle driver's eyes. Thus, the visor (81) or sun blocker is automatically positioned depending upon the azimuth (.psi.) and elevation (.theta.) angles of the sun direction relative to the driver's eyes. Those angles are detected by photo-responsive elements (61) that produce signals indicative of the azimuth and elevation angles of the sun, that initiate positioning the sun blocker (81) laterally and extending it downward to block the sun so that it does not strike the driver's eyes. In a particular embodiment, a visor (81) on a track (71) above the windshield (1) is driven laterally to predetermined positions depending upon the direction of the sun and is automatically extended (downward), as required, to block the sun so that it does not strike the driver's eyes.
