(54) A shielding device


(57) A shielding device comprises a fabric (3) defining a plurality of meshes which are designed to assume a restricted configuration and a stretched-out configuration, and actuation means (4) made of active material, which are operatively connected to the fabric (3) and can be activated to bring about passage of said meshes from the restricted configuration to the stretched-out configuration, and vice versa. The actuation means are preferably in the form of a thread (4), interwoven or in any case anchored to the fabric, made of a shape-memory alloy or polymer, or of an electro-active polymer. The device finds, for example, application in the construction of shields for light beams, windows or panels for aeration/ventilation, and filters for adjustable cross section.
