An aircraft passenger cabin window construction is formed by a casing of modular elements that are easily assembled and permit using substantially larger inner window panes compared to the area size of outer window panes thereby avoiding forming a funnel configuration or effect. For this purpose a window sill (8) is provided with lateral upward extensions (8B) and (8C) to provide a U-configuration that is held in place by casing elements (6) and (7). The casing elements (6, 7) may simultaneously form inner cabin wall panels and also reach upwardly with extensions (6A) and (7A) to form a further U-configuration cooperating with the first mentioned U-configuration of the sill (8). The upper open end of the two U-configurations is closed by a casing element (10). An inner window pane is supported or covered by the window sill. A central casing element (9) extending vertically may divide the U-shaped configurations into at least two sections.
A passenger aircraft cabin window casing comprising a plurality of modular casing elements forming a modular casing unit, said plurality of casing elements comprising at least one lower first casing element (6, 7) forming an upwardly open lower frame component (6A, 7A) and lateral frame components (6B, 7B), at least one upwardly open intermediate second casing element (8) forming a window sill as part of said window casing, said window sill (8) having a central lower sill portion (8A) and lateral upwardly reaching sill extensions (8B, 8C) along said lateral window frame components (6B, 7B), said at least one lower casing element (6, 7) having a sill facing edge (6C, 7C) forming a mounting for said window sill (8), said window sill (8) being positioned below at least one inner window pane (4B, 4B′).
An aircraft window construction comprising a window casing, at least one outer window pane and at least one inner window pane mounted in said window casing, said window casing comprising a plurality of casing elements forming a modular casing unit, said plurality of casing elements comprising at least one lower casing element forming upwardly open lower window frame components and lateral window frame components, at least one upwardly open intermediate casing element forming a window sill (8) as part of said window casing, said window sill having a central lower sill portion and lateral upwardly reaching sill extensions along said lateral window frame components, said at least one lower casing element having a sill facing edge (6C, 7C) forming a mounting for said window sill (8), and wherein at least one inner window pane is positioned above said window sill.
