Abstract
A horizontal window blind for virtually total blocking the passage of light has a plurality of slats formed from first and second portions parallel to each other. The portions are interconnected by a transition portion, and a flange portion is provided projecting at an obtuse angle from the second portion. At least one opening is made in the flange portion to pass a lifting cord therethrough. The slats are supported by horizontal cords which are attached to a set of vertical cords. A spacing between the horizontal cords is fixed to a distance which permits an outer edge of the first portion to cover the flange portion with the cord passage opening and at least a part of the second portion when the slats are tilted into the vertical position. Because of the shape of the slats and the relative positioning of the slats when tilted into the vertical position, the lifting cord does not find its way between the slats and light is fully blocked by the blind.
