Flexible slats rigidified by coiled formations along the longitudinal edges are hingedly interconnected by interleaving of the coiled formations to form a continous, foldable window shade, or are interconnected by flexible spacers at the ends for simultaneous pivotal displacement as shutter blinds by an actuator device hingedly connected to the coiled edge formations. An intermediate bar formation integral with each slat, has pivot extensions projecting from each end of the slat into vertical guide tracks for pivotal support.
