ABSTRACT:
This invention concerns a flexible shutter system combined with drive systems in such a way as to permit the shutter (1) to move vertically between a closed position and an open position, said shutter (1) being intended to close an opening (5) or other aperture, the shutter (1) having at least one area of low resistance (11) which, in the closed position, extends from the lower edge (4) of the shutter (1) to a certain height on the latter (1), in such a way as to permit the creation of at least one access aperture if the shutter (1) is broken at the location of said area of low resistance (11).
