The blind has a set of lamellae (3) connected with one another and movable from a winded position to a laminar position in front of a building opening. The lamellae form an opaque surface in the laminar position and form a translucent surface (4) in the winded position, where the lamellae covers an upper region of the building opening in the winded position. The lamellae are movable using a pulling device arranged above the lamellae. |
