The blind (1) is in its closed position tightened by an edge connection which comprises a longitudinally suspended, flexible membrane (10), which can be the blind itself interacting or cooperating with the edge (5) of a tightening moulding (3) or a loose longitudinally suspended membrane (10) interacting or cooperating with the edge (2) of the blind (1). The tightening is obtained when the blind or the membrane is pressed against the edge (5 or 2), respectively, by an air pressure difference between the outer and the inner side of the blind conditioned by the temperature difference. <IMAGE> |
