Description

[0001] The invention relates to a window of a passenger cabin of an aircraft, wherein the window comprises a fuselage pane integrated into a fuselage of the aircraft and extending transversely to the direction of view, and at a distance from this, a cabin-side inner pane extending parallel to it. The window also has a window funnel that extends along the direction of view, framing the space between the inner pane and the fuselage pane.

[0002] From DE 10 2007 006 540 A1, an aircraft window arrangement is known. This comprises a window funnel to which a retaining ring for attaching a cabin-side window pane is attached. The window funnel extends essentially from the side wall paneling of the aircraft cabin to an outer window pane of the aircraft.

[0003] Further aircraft window arrangements are known from DE 10 2021 125 960 B4, DE 10 2011 108 167 B4 and DE 10 2009 031 523 B4.

[0004] The object of the present invention is to propose improvements with regard to such a window.

[0005] The problem is solved by a window housing according to claim 1. Preferred or advantageous embodiments of the invention and of other invention categories will become apparent from the further claims, the following description and the accompanying figures.

[0006] The window housing is designed for a passenger cabin window of an aircraft. The invention is based on the following window / passenger cabin / aircraft configuration: The window has a fuselage pane. This pane is integrated into the fuselage of the aircraft and extends transversely to a viewing direction. This direction leads from the passenger cabin through the window to the outside of the aircraft.

[0007] The window has a cabin-side inner pane, positioned opposite but parallel to the direction of view and at a distance from the fuselage window. This inner pane extends parallel to the fuselage window. The inner pane is also called the "interior window (on the inside of the cabin)." The aircraft is primarily a passenger aircraft.

[0008] "Intended use" means that the window housing is structurally designed and configured for specific types of windows, passenger cabins, and aircraft; for example, it is designed to meet the resulting geometric and material requirements, etc. In other words, the specific windows, passenger cabins, and aircraft in question are assumed to have known geometric and material properties, etc. Specifically, the aforementioned properties of the window, passenger cabin, and aircraft are assumed.

[0009] The window housing contains a window funnel. This funnel can be attached to the aircraft, specifically to the fuselage / a structural component of the aircraft / fuselage, or is actually attached in the passenger cabin / aircraft when the window housing is properly installed. In its installed state, the window funnel extends along the line of sight between the inner pane and the fuselage window, thus framing the line of sight and the space between the two panes.

[0010] The term "extends between" is to be interpreted broadly here: The window funnel can end at the inner pane or, in the direction of view, in front of or behind it; in particular, the window funnel projects towards the interior of the aircraft, i.e., inwards, beyond the inner pane. Alternatively or additionally, the window funnel ends at the fuselage window or, within the cabin, in front of the fuselage window.

[0011] The window funnel is made of foam.

[0012] The window housing contains at least one functional component that is attached to the window funnel. This attachment can be achieved, for example, by inserting or attaching the functional component to the finished, foamed window funnel after it has been completed / foamed.

[0013] In particular, the integrated window funnel creates a light-tight seal between the two panes (inner pane and outer pane). Specifically, the window funnel incorporates various functions through the unique shape of the foam. One such function could be, for example, a contact surface for the inner pane. For this purpose, the foam has a contact surface for the inner pane, which, when installed, rests against this surface on the window funnel and is thus functionally secured in place.

[0014] The use of foam / foam material - especially particle foam - offers the following advantages compared to injection molding material: • The density is approximately 10-20 times lower (weight reduction of approximately 25%), • improved damping properties in terms of acoustics, • lower thermal conductivity.

[0015] The foam combines the following properties, which contribute to improving the window casing: - Structure of the window funnel and integration of the functional components, - lower heat transfer compared to injection-molded parts known from practice, - better acoustic properties compared to the injection-molded part known from practice.

[0016] In a preferred embodiment, the foam is a particle foam. In other words, it is particle foam, which is typically produced from foam particles (beads) fused together in a mold. Components of this type can be manufactured particularly well and to a high standard from particle foam. In other words, the window funnel is made of foam, with particle foam being the preferred material variant.

[0017] In a preferred embodiment, at least one of the functional components is attached to the window funnel by being embedded in the foam as an insert. By appropriate foaming, the functional components can be attached to the window funnel particularly easily and effectively.

[0018] In a preferred embodiment, at least one of the functional components is a fastening component. The fastening component is one by means of which the window housing can be attached to the aircraft, i.e., to a fuselage / structural part of the aircraft / passenger cabin (and is secured in the installed state). Such structural parts include, for example, the fuselage or attachments thereto, an interior lining of the passenger cabin, a base frame, a bracing in the aircraft / passenger cabin, etc. For example, the fastening component is a flange with a bore for screwing the window housing to the structural part. However, the fastening component can also be a guide or holder for another or secondary fastening element, such as a dowel, a clamp, or a clip.Finally, the additional fastening element takes over the actual fastening of the window funnel - indirectly via the fastening component - to the structural part.

[0019] By integrating such fastening components into the window funnel, it can be particularly well secured in the aircraft.

[0020] In a preferred embodiment, the intended window is assumed to include a retaining element, wherein the retaining element can be attached to or is attached to the window funnel (and optionally detachable). The retaining element, particularly together with the window funnel, is designed to hold the inner pane to the window funnel. The retaining element is, for example, a retaining ring. This ring, together with the window funnel, is designed to positively lock the inner pane between the retaining ring and the window funnel, or to clamp it between them in the direction of view.

[0021] At least one of the functional components is a retaining component designed to hold or attach the retaining element to the window funnel. Thanks to the retaining component, the retaining element, and therefore also the inner pane, can be securely attached to the window funnel.

[0022] In a preferred embodiment, the retaining element is assumed to have a positive-locking counterpart. The retaining component is then a positive-locking component designed to interact positively with the positive-locking counterpart of the retaining element in the assembled state, thereby securing the retaining element to the window funnel. This positive locking between the positive-locking component and the positive-locking counterpart allows the retaining element to be particularly securely attached to the window funnel.

[0023] In a preferred embodiment, the positive locking counterpart is assumed to be a locking lug. The positive locking component is then an undercut for the locking lug (e.g., a stop shoulder / plate).

[0024] Alternatively, the reverse configuration is also possible: the interlocking counterpart is the undercut and the interlocking component is the locking lug. This results in a particularly simple and effective interlocking mechanism that is also lockable, thus simplifying the installation of the retaining element on the window funnel.

[0025] In a preferred embodiment, the window is assumed to contain a shade. The shade is designed to darken the window more or less as needed. For this purpose, the shade is adjustable (e.g., by a passenger in the passenger cabin). The shade is, for example, a slider or a roller blind, and is particularly lightproof. By adjusting, sliding, or operating the shade, the window can be darkened more or less, thus allowing more or less light from outside the aircraft to enter the cabin.

[0026] At least one of the functional components is a guide component for the blind, allowing it to be adjusted by means of guidance from the guide component (i.e., to darken the window to a greater, lesser, or complete degree). The guide component is, for example, a sliding / running rail for a slider, which can then be moved along the rail.

[0027] Thus, the window housing (at least partially) also takes over the function of guiding the aperture, which is why any additional aperture guidance outside the window housing can be implemented more easily or can be dispensed with entirely.

[0028] In a preferred embodiment, at least two of the functional components are jointly formed as a combination part in the form of a single insert for the foam of the window funnel. In particular, the combination part is manufactured in one piece. For example, the combination part is a window frame that at least partially surrounds the window funnel (circumferentially around the viewing direction). This can, for example, be designed as the guide rail for the cover, to which interlocking components for the interlocking counterparts, retaining components for the retaining element, and fastening components for attaching the window funnel to structural parts of the aircraft are molded (e.g., connected via webs). Thus, it is possible, for example, that only the combination part needs to be inserted as a single insert into a tool or a foam mold for the window funnel. The foam mold can then be filled with foam to produce the window funnel.In this process, all desired functions (of the functional components) are integrated into the window funnel in a single step. Therefore, all functional components can be attached to the window funnel in one work step, and the funnel itself can be manufactured.

[0029] The problem is also solved by a window module according to claim 10. This includes the window housing and the inner pane as already described above, wherein the window housing and inner pane are in the assembled state.

[0030] The background to this is as follows: The fuselage window is not part of a so-called "window unit," i.e., the window module. The fuselage window is usually permanently installed in the aircraft. The window funnel simply connects to the fuselage window / window. The window housing / module is attached to the interior sidewall. The complete interior sidewall with the interior window then forms a single assembly. During installation in the aircraft, the complete assembly is inserted and, during assembly, forms the transition between the fuselage window / window and the interior.

[0031] The window module and at least some of its possible embodiments, as well as their respective advantages, have already been explained in substance in connection with the window housing according to the invention. In particular, the preferred embodiments mentioned above in connection with the window housing also constitute preferred embodiments of the window module.

[0032] The object of the invention is also achieved by a window according to claim 11, as already described above. The window is therefore one for the intended passenger cabin of the aircraft, as described above. As explained above, the window comprises the fuselage window, which can be integrated into the fuselage of the aircraft (integrated in the intended assembly state), and the inner pane, which in the intended assembly state is arranged at a distance from and parallel to the fuselage window. The window includes the window housing according to the invention. In particular, the inner pane is attached to the window funnel.

[0033] The window and at least some of its possible embodiments, as well as their respective advantages, have already been explained in substance in connection with the window housing according to the invention. In particular, the preferred embodiments mentioned above in connection with the window housing also constitute preferred embodiments of the window.

[0034] The object of the invention is also achieved by an aircraft according to claim 12, as already explained above. This aircraft includes – as explained – the passenger cabin mentioned above and at least one of the windows mentioned above (and thus the window housing), which is located in the aircraft or the passenger cabin in its intended assembly state.

[0035] The aircraft and at least some of its possible embodiments, as well as their respective advantages, have already been explained in substance in connection with the window housing and the window according to the invention. In particular, the preferred embodiments mentioned above in connection with the window housing and the window also constitute preferred embodiments of the aircraft.

[0036] The object of the invention is also achieved by a method according to claim 13. This serves to manufacture the window housing according to the invention, as explained above, in particular in the embodiment mentioned with at least one functional component which is foamed in as an insert in the foam / in particular particle foam.

[0037] In this process, a foam mold is provided for the window funnel. Specifically, the functional components (inserts) to be foamed in are placed into the mold. These are typically fixed in place to ensure they are positioned correctly within the window funnel after the foaming process. The window funnel is then manufactured by injecting the foam into the mold (i.e., by foaming). During this foaming process, and subsequently, the functional components are attached to the window funnel, primarily by encasing or surrounding them with foam.

[0038] The method and at least some of its possible embodiments, as well as their respective advantages, have already been explained in substance in connection with the window housing, window, and aircraft according to the invention. In particular, the preferred embodiments mentioned above in connection with the window housing, the window, and the aircraft also constitute preferred embodiments of the method.

[0039] The invention is based on the following findings, observations, and considerations and further comprises the following preferred embodiments. These embodiments are sometimes referred to simply as "the invention." The embodiments may also include parts or combinations of the embodiments mentioned above, correspond to them, and / or may include previously unmentioned embodiments.

[0040] According to the invention, a foam interior window housing with integrated functional components for the aviation sector is obtained.

[0041] The "foam interior window housing" assembly is primarily used for creating a light-tight seal between interior windows (cabin interior, inner pane) and fuselage windows (fuselage windscreen) in aircraft. Unlike conventional window housings, this component (window funnel) is made of a lightweight foam material. Functional components are integrated within the foam housing and / or via foam-encased inserts (functional components).

[0042] The invention is based on the idea of ​​reducing the weight of the aircraft interior side wall.

[0043] The invention is based on the observation that in practice, corresponding assemblies of the window housing (window funnel) are mainly made up of injection-molded parts.

[0044] According to the invention, the injection-molded housing is replaced by a foam housing (window funnel). The density of the foam is significantly lower than that of the injection-molded material. Functions are integrated accordingly within the foam housing and / or via foam-encased inserts.

[0045] The construction (window housing) requires, in particular, various freestanding, foam-encased inserts (functional components) to fulfill the functions of products (window housings) known from practical applications. The foam construction is also an integral construction method. It primarily provides the structural framework of the window housing and simultaneously offers lower thermal conductivity and improved acoustic damping properties.

[0046] The foam housing (window funnel) absorbs forces and guides functional components, as well as shielding the fuselage window (window pane) from light entering the interior wall. The wall thickness of the foam construction is greater than that of injection-molded housings commonly used in practice. Functions are integrated within the foam housing and / or via foam-encased inserts. These inserts are mounted on corresponding tooling fixtures (foam molds) and then back-foamed (foaming the window funnel). The tooling (foam mold) serves to position the inserts (within the window funnel) and is specifically designed to allow for undercuts (form-fit components).

[0047] Further features, effects, and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and the accompanying figures. These figures are shown in a schematic diagram: Fig. 1. A section of an aircraft or its passenger cabin with a window and window housing. Fig. 2 a section through the window housing Fig. 1 along line II-II. Fig. 3 the detail III from Fig. 1, Fig. 4 the combination part made of Fig. 3 omitting the window funnel, Fig. 5 a rear view of the window housing from Fig. 1 in the direction of arrow V with a fastening component as a holder for a secondary fastening device.

[0048] Fig. Figure 1 shows a section of an aircraft 2, namely its passenger cabin 4. This contains a window 6. The window 6 is in an assembly state M in the aircraft 2.

[0049] Along a viewing direction 8, which is directed from passenger cabin 4 towards the outside of aircraft 2 (arrow in Fig. 1) The window 6 has an inner pane 14 and a fuselage pane 10. The latter is integrated into a fuselage 12 of the aircraft 2 and extends transversely to the direction of view 8. At a distance A along, but opposite to the direction of view 8, the inner pane 14 extends parallel to the fuselage pane 10.

[0050] Window 6 contains a window housing 20. The window housing 20 contains a window funnel 22. As explained, this is attached to an interior side wall of aircraft 2 (not shown in detail). Along the viewing direction 8, the window funnel 22 extends between the inner pane 14 and the fuselage window 10. "Between" is to be understood broadly: The window funnel 22 projects beyond the inner pane 14 towards the passenger cabin 4 and extends to the fuselage window 10, i.e., it terminates at it. The window funnel 22 frames the two panes, or rather the viewing direction 8, and therefore blocks light from the space between the inner pane 14 and the fuselage window 10 with respect to its radially outer surroundings (relative to the viewing direction 8). The window funnel 22 is made of a foam 24, in this case, particle foam.

[0051] The window housing 20 also contains several functional components 26, which are explained in more detail below and are all attached to the window funnel 22. In this example, all functional components 26 are attached to the window funnel 22 by being embedded as inserts 28 in the foam 24.

[0052] The window 6 also includes a retaining element 16, which in assembly state M is attached to the window funnel 22 and thereby holds the inner pane 14 to the window funnel 22. More precisely, the retaining element 16 clamps the inner pane 14 between itself and the window funnel 22 (a contact surface 30 on it) in the direction of view 8.

[0053] To better illustrate, shows Fig. 1 a partial exploded view of the situation with regard to window funnel 22, inner pane 14 and retaining element 16.

[0054] The window funnel 22 has the following function solely due to its shape: The foam 24 is shaped to form the contact surface 30, which in assembly state M points towards the passenger cabin 4 and on which the inner pane 14 rests with its outer surface facing the fuselage 12 and is thus supported on the window funnel 22.

[0055] Four of the functional components 26 are designed as fastening components 32a, b, d, e. The window funnel 22 is attached to structural parts 34 of the aircraft 2, specifically an interior side wall (not shown in detail), by means of the fastening components 32. Only one of these interior side walls is shown in the figure as an example. The fastening components 32 are designed as flanges with bores 36. The fastening components 32, and thus the window funnel 22, are attached to the structural part 34, and therefore to the fuselage 12 of the aircraft 2, by means of screws 38 through the bores 36.

[0056] The fifth functional component 26, as a fastening component 32c, is welded as an attachment 27 to the window funnel 22 (finished foam component), without being an insert 28.

[0057] Eight of the functional components 26 are designed as retaining components 35 for the retaining element 16 in order to attach it to the window funnel 22. In Fig. In Figure 1, four of these retaining components 35 are visible. In this example, the retaining element 16 has positive-locking counterparts 37, here in the form of locking lugs 39. The retaining components 35 are therefore positive-locking components 40, which, in the assembled state, interact positively with the positive-locking counterparts 37. The positive-locking components 40 are undercuts 42 in the form of stop plates, which, in the assembled state M, are positively engaged by the locking lugs 39 in order to press the retaining element 16 against the window funnel 22, clamping the inner pane 14.

[0058] Window 6 contains a shade 18. This is designed to darken or undarken window 6 as needed against ambient light from outside the aircraft 2, by partially or completely sliding the shade 18 – for example, by a passenger (not shown) – in the direction of arrow 50 towards the cabin side, in front of the inner pane 14. To reduce the darkening, the shade 18 can be moved in the opposite direction to arrow 50.

[0059] Two of the functional components 26 are designed as guide components 52 for guiding and thus adjusting the aperture 18. The guide components 52 are guide, sliding, or running rails for the aperture 18, which is designed here as a slider, extending along the direction of arrow 50. The guidance of the aperture 18 is completed by a cabin-side cover element (not shown), which holds the aperture 18 in the guide components 52 on the cabin side.

[0060] All functional components 26 are here combined into a single unit 54 in the form of a window frame. The unit 54 thus forms the only insert 28 for the window funnel 22 or its foam 24.

[0061] In Fig. It is evident from the combination part 54 that the guide components 52 are designed as parts or longitudinal webs – rails – of the window frame. The fastening components 32 are integrally molded onto these. The molding of the retaining components 35 is shown in the Fig. 2, Fig. 3 to Fig. 4 are recognizable. These are formed via webs 56 as part of the combination part 54 to the remaining functional components 26.

[0062] Fig. 2 shows a section along line II - II through the in Fig. 1. Left part of the window housing 20. Here it can be seen how the guide component 52 is connected to the retaining component 35 via the web 56 and how the combination part 54 is embedded in the foam 24. The design of the retaining component 35 as an undercut 42 for the locking lug 39 on the retaining element 16 is also symbolically illustrated here. A recess, not further explained, is provided in the window funnel 22 for the locking lug 39.

[0063] Window housing 20 and inner pane 14 together form a window module 72, which as such is used during assembly in the aircraft 2 with the fuselage window 10 already mounted.

[0064] Fig. 2 symbolizes the process for manufacturing the window housing 20.

[0065] In the process, in step S1, a foam mold 70, indicated here only by dashed lines, is provided for the window funnel 22, which thus defines the outer surfaces of the window funnel 22 to be created in a manner customary in the trade by means of its internal volume or its internal wall.

[0066] In the present case of foamed-in functional components 26, these - here as the combination part 54 - are fixed in the foam mold 70 in a step S2.

[0067] Subsequently, in step S3, the foam 24 is introduced into the foam mold 70, thereby manufacturing or foaming the window funnel 22. The functional components 26, as the combination part 54, are also foamed in and thus attached to the window funnel 22 formed from the foam 24.

[0068] Fig. 3 shows the situation Fig. 2 without holding element 16 again in perspective view as detail III from Fig. 1. Here, the guide component 52 in the form of a slide rail, the web 56, and the retaining component 35 in the form of the undercut 42 are particularly visible. The contact surface 30 for the inner disc 14 is also visible.

[0069] Fig. 4 shows the situation Fig. 3, omitting the foam 24, which is why the combination part 54 is shown on its own. The individual functional components 26 are thus more easily recognizable.

[0070] Fig. 5 points in the direction of arrow V in Fig.1, i.e., in a diagonally rearward view of the window funnel 22, a further fastening component 32f is visible as a functional component 28. This is initially, or merely, a holder 60 for a secondary fastening element 62. The fastening element 62 is a dowel, which accomplishes the actual fastening of the window funnel 22 to another structural part 34 of the aircraft 2, which is not shown. The fastening of the window funnel 22 is therefore indirect, i.e., indirectly, in that the fastening element 62, which is directly attached to the structural part 34, is held by the fastening component 32, and this in turn is fastened in the window funnel 22.
