Abstract:
1. A transparent device for protection from an action of shock, projectiles, fragments or shock waves, comprising: a laminate having four brittle-fracture, transparent panels that are joined together by transparent intermediate layers, the transparent intermediate layer being formed of casting resin or being formed of polymer film, the laminate having a total thickness of at least 60 mm and the laminate being closed, on a protective side facing away from a side of action, by a fragment-protective layer having a thickness of 0.5 mm to 12 mm, which is formed as a transparent polymer layer, the laminate being closed on a side facing the side of action by one of the four brittle-fracture, transparent panels that comprises a first, chemically prestressed, brittle-fracture panel; and a polymer layer of a thickness between 2 mm and 15 mm is disposed via a polyurethane layer on a surface of the first, chemically prestressed, brittle-fracture panel that faces away from the side of action.
