1. Device for protecting structures having at least one fabric (11, 11'), a winding means (45) for the same fixed to one end of the fabric and associated with a mechanism for tensioning said fabric, which comprises at least two cables (49, 50) respectively extending from winding pulleys (47, 48) keyed to the winding means (45) to return rollers (51, 52) mounted at the point of maximum unwinding of fabric (11, 11') on which it is deflected by approximately 180 degrees in order to rejoint, via rollers (53, 54), the guide section (20) fixed to the other end of the fabric in which the two cables (49, 50) are kept taut by a spring (55), characterized in that the spring (55) is integral with two rollers (57, 58) on which are deflected the respective cables prior to being fixed in the interior of the guide section (20) to fixing points (59, 60). |
