Patent ID: 7929194

Claim:
Glazing suitable for a side or front window for an airplane or helicopter cockpit, comprising, in succession: a first rigid substrate (S 1 ) comprising an outside face to be outside of the cockpit; a second rigid substrate (S 2 ); a third rigid substrate (S 3 ) comprising an inside face to be inside the cockpit, wherein the second rigid substrate (S 2 ) positioned between the first rigid substrate (S 1 ) and the third rigid substrate (S 3 ), wherein the substrates are made of thermally semi-toughened or chemically toughened glass; a first active system (A) that includes at least one layer and is positioned between substrates (S 1 ) and (S 2 ), a second active system (B) that is a thin-film multilayer system comprising a heating function and positioned between the substrates (S 1 ) and (S 2 ), wherein the first substrate (S 1 ) is set back in relation to the other two substrates (S 2 ) and (S 3 ) with a set back zone around the periphery of the first substrate (S 1 ); and at least one polymer film (F 1 , F 2 ) functioning as an adhesive interlayer and retaining glazing fragments should the glazing break, said film positioned between substrate (S 1 ) and substrate (S 2 ) and between substrate (S 2 ) and substrate (S 3 ), and a seal (J 3 ) that encapsulates the substrates (S 1 ), (S 2 ) and (S 3 ) and that covers the set back zone and periphery of the first rigid substrate (S 1 ).
