Abstract: A sunshielding accessory for motor vehicles, includes a sun visor panel for pivotal mounting to the vehicle above the windshield to either an upper inoperative position overlying the windshield, or to a lower operative position covering only an upper portion of the windshield; and an assembly of sunshield panels carried by the sun visor panel. The sunshield panels are joined to each other in accordion fashion and are foldable along fold lines against each other into a folded inoperative form depending below the sun visor panel, with the fold lines extending perpendicularly to the longitudinal axis of the sun visor panel, against the sun visor panel, or to an extended operative form to cover a substantial portion of the windshield below the sun visor panel when the latter is in its lower operative position. Retainer means releasably retains the sunshield panels in their folded inoperative form against the sun visor panel.
