Abstract (en)
The sheet serves for cases of emergency. in particular for covering compartments containing emergency means, fire fighting means, alarm means and the like. The surface of the sheet comprises a lattice of linear incisions (10) of preferential fracture (11, 11'), each of which forms, in section, a recess which narrows towards the point of minimum level where it defines a preferential fracture line; said lattice of linear incisions defines a plurality of mutually adjacent closed sheet portions (20, 25) bounded by and separated from each other by the preferential fracture lines (11, 11'); according to the invention, at the nodal points, said preferential fracture lines (11, 11') join together in pairs to form chamfer lines (13, 13') bounding a closed nodal area (30) within which the thickness is much smaller than the overall thickness of the sheet. This overcomes the drawback caused by the fact that at the nodal points where the lines intersect, acute angles form along the fracture lines when the sheet is broken, and represent a danger to the person breaking the sheet, especially if using a hand to directly break the sheet. <IMAGE>
