A retractable covering for architectural openings having collapsible vanes includes a head rail and support structure in the form of a sheet of material, monofilaments, tapes, ribbons, cords, or the like, supporting an upper edge of a plurality of vertically spaced, horizontally extending vanes with the lower edges of the vanes being connected to operating elements adapted to raise the lower edges of each vane toward the upper edges to define openings or gaps between the vanes through which vision and light can pass in an open condition of the covering. The support structure, vanes and operating elements are adapted to be wrapped around a roller in the head rail in a retracted position of the covering and unwrapped in an extended position. An inhibitor system is incorporated into the covering to permit automatic opening of the vanes when the support structure, vanes and operating elements reach an extended position.

L'invention concerne un dispositif de recouvrement rétractable pour ouvertures architecturales possédant des lamelles pliables comprenant un rail de tête et une structure support sous forme de matière en feuille, de monofilaments, de bandes, de rubans, de cordes ou analogue, supportant un bord supérieur de plusieurs lamelles s'étendant horizontalement, espacées verticalement avec les bords inférieurs des lamelles reliés à des éléments d'actionnement conçus de manière à élever les bords inférieurs de chaque lamelle vers les bords supérieurs afin de définir des ouvertures ou des espaces entre les lamelles à travers lesquelles la vision ou la lumière peuvent passer en condition ouverte du recouvrement. La structure support, les lamelles et les éléments d'actionnement sont conçus de manière à être enroulés autour d'un rouleau dans le rail de tête en position rétractée du recouvrement et déroulés en position étendue. Un système inhibiteur est introduit dans le recouvrement afin de permettre une ouverture automatique des lamelles lorsque la structure support, les lamelles et les éléments d'actionnement atteignent une position étendue.
