Sun visor apparatus for vehicles

摘要

An apparatus for preventing the driver of a vehicle from being blinded by the glare of light by selectively moving a light-shielding plate in two-dimensions along an inside surface of the windshield to provide a light-shielding region. The light-shielding plate is controllably moved by hand or by motor. More preferably, the apparatus further includes a microcomputer for obtaining the crossing point between light coming into the eye of the driver and the windshield plate, and a mechanism or circuit for moving the light-shielding plate to a shielding position defined by the microcomputer.
