Embodiment Construction

[0040] Figure 1 to Figure 3 The shown glazing 1 according to the invention is intended to be accommodated in the fuselage / structure 2 of an aircraft.

[0041] In known manner, the glazing 1 comprises at least one layer, preferably multiple layers arranged as a laminate.

[0042] exist figure 1 In the example of a glazing, the glazing 1 comprises three layers, the first layer corresponds to a first substrate 10 made of glass, the first substrate is preferably strengthened (thermally strengthened or chemically strengthened) glass typically 8 mm thick, The second layer consists of a second substrate 11, likewise made of glass, preferably reinforced and typically 8 mm thick, the two glass substrates 10 and 11 being fixed to each other by an interlayer 12 of PVB type , and the third layer consists of a third glass substrate 13, usually 3 mm thick, and an intermediate sheet 14, usually 6 mm thick, made of a plastic material such as PU, which connects the second glass substrate 11...

Abstract

Glazing unit (1) comprising at least one structural substrate (10, 15), termed inner substrate, intended to face towards a receiving structure (2) within which the glazing unit is intended to be fastened, and having a face (10A, 15A), termed inner face, characterized in that said inner face (10A, 15A) of said substrate comprises, projecting therefrom and at the edge or in the vicinity of the edgeand on at least one of the sides of the glazing unit, at least one male or female retaining element (5) intended to cooperate with at least one respectively female or male retaining shape (2A) arranged in the glazing unit receiving structure.

Description

technical field [0001] The invention relates to a glazing which is fixed by clamping in a nacelle such as in an aircraft structure, the glazing being capable of being bloquered in its receiving opening in the event of a breakage of a layer of the glazing. [0002] Although not limited thereto, the present invention will be described more particularly with reference to the field of aviation. Background technique [0003] When the aviation glazing is made entirely of plastic material, it is fastened to the aircraft structure by clamping or preferably by drilling and bolting. [0004] In the case of glazing made of glass, since no holes should be drilled, it can be fixed by clamping its peripheral edge and its two opposite outer faces, or by gluing to the glazing and bolting Secure the interface elements to the aircraft structure. [0005] The bolted glazing is fastened to the aircraft structure, and therefore, all deformations of the aircraft structure caused by pressurizati...
