  • Patent number: 4570991
    Abstract: An elongated sun visor panel of either opaque or tinted material is pivoted on the vehicle body adjacent the juncture between the windshield pillar and the windshield header to enable pivotal movement between a vertical stored position overlying the windshield pillar and a horizontal position partially obstructing either the windshield opening or the side window opening. The elongated panel is preferably divided by a living hinge which provides a longitudinal extending hinge axis by which the panel may be folded to closely overlie the shape of the windshield pillar. A pair of such sun visor panels are preferably provided to enable simultaneous shielding of the occupant relative both the windshield and the side window. The sun visor panel is preferably held in the use position and the stored position by Velcro fasteners, magnets, or a detent associated with the pivot.
