摘要：
A protection device (100), comprising:
- a plurality of metal lamellae (1), each having a first front wall (2A) and a second rear wall (2B), arranged as a sequence and overlapped with each other so that the first front walls (2A) define, as a whole, a continuous closing surface (3), said lamellae (1) being relatively movable along a first moving direction (D1) in order to modify in at least an area of the continuous closing surface (3) the overlapping degree between at least a portion of said metal lamellae (1),
- a plurality of dragging modules (4), arranged at the second rear wall (2B) of the lamellae (1) in different operative regions (R1, R2, R3) with respect to a second direction (D2) orthogonal to the first direction (D1) so to occupy only partially the rear area corresponding to the closing surface (3), each dragging module (4) comprising:
- a bellows piece (5);
- a plurality of supporting frames (6);
- an extension limiting strap (7);
and wherein
- each supporting frame (6) is fastened to the second wall (2B) of a metal lamella (1) at a coupling area;
- said bellows piece (5) is interposed and blocked between each supporting frame (6) and the respective metal lamella (1) so to define ridges (C) and valleys (V) between each supporting frame (6) and the next one.
