Abstract

A self-opening and -closing shutter has a stiff shutter blade (4), arranged with its edges close up against its seating (2, 3). The shutter blade can turn around an essentially horizontal shaft (7). The part of the shutter blade, which lies under the shaft, has a greater area than the part above the shaft. To ensure a stable open position, the lower part at least of the shutter blade is fitted with an air deflector (13), arranged to build an air pressure force against the shutter blade's surface.<IMAGE>
