An external screening device for a pivotable skylight window comprises a web (5) of a screening material which is wound on a spring-biased roller (11) and is connected with a bottom bar (7) guided in side guide rails (9, 10) which is connected via a cord drive (14, 15) with an unrolling drive unit (12, 13). The side guide rails (9, 10) for the bottom bar (7) run along the parts (3) of the frame side portions situated above the axis of rotation (2) and the parts (4) of the sash side portions situated below the axis of rotation (2), and an essentially rod-shaped support device (8) is attached to and extends across the screening web (5) and is led in the side guide rails (9, 10) so that in a position of use for the screening device it is positioned at or close to the axis of rotation (2) in parallel therewith. The device may be provided with means for retightening and smoothing the web (5) in the fully drawn position and during rewinding.

L'invention porte sur un pare-soleil extérieur pour tabatière pivotante comprenant une toile (5) d'un matériau écran enroulée autour d'un rouleau rappelé par ressort (11) et solidaire d'une barre inférieure (7) guidée par des rails latéraux (9, 10) et reliée par un cordon de commande (14, 15) à une unité de déroulement (12, 13). Les rails latéraux (9, 10) de guidage de la barre inférieure (7) sont disposés le long des portions (3) des parties latérales du cadre situées au-dessus de l'axe de rotation (2) et le long de la portion (4) des parties latérales du châssis situées au-dessous de l'axe de rotation (2), tandis qu'un support sensiblement en forme de tube (8) fixé à la toile écran (5) et la traversant est engagé dans les rails latéraux (9, 10) de manière à se trouver, quand la toile écran est déployée, sur ou à côté de l'axe de rotation (2), tout en lui étant parallèle. Le dispositif peut comporter des moyens pour tendre ou détendre la toile (5) en lorsqu'elle est entièrement déployée ou pendant son réenroulement.
