Abstract: An infant seat sun visor apparatus is set forth wherein a mounting yoke is secured in overlying relationship to an existing infant seat with a forward "U" shaped pivotally mounted sun visor pivotally mountable relative to the mounting yoke by a plurality of spring clamps formed with interacting serrated teeth to angularly position the visor relative to the yoke, as desired. The yoke is provided with a downwardly depending "T" shaped abutment member positionable rearwardly of the seat including a plurality of interiorly positioned friction pads to frictionally maintain the apparatus in position relative to the infant seat. Protective resilient molding is formed about the edges of the pivotally mounted visor to enhance protection of an infant. The sun visor apparatus of the instant invention enables the infant to be shaded from sun's rays while simultaneously limiting obstruction of vision of the infant.
