Abstract
A transparent device for protection from an action of shock, projectiles, fragments or shock waves is provided. The device is a laminate having brittle-fracture, transparent materials that are joined together by way of transparent intermediate layers of organic polymers. The laminate is closed on the protective side facing away from the side of action by a fragment-protective layer that is formed as a transparent polymer layer in a thickness of 0.5 mm to 12 mm. The laminate has facing the side of action a chemically prestressed, brittle-fracture panel that is at a distance of 3 mm to 20 mm from the side of action.
