Description

Technical Field

[0001] The present invention relates to a cabin module for an aircraft, an aircraft, a method for creating a cabin module for an aircraft, and the use of the cabin module in an aircraft. Background Technology

[0002] To ensure passenger hygiene, aircraft fuselages are equipped with sanitation units, such as toilets. To utilize space on the fuselage as efficiently as possible, the sanitation areas are designed to be as compact as possible to save space. Reduced space can impede use by passengers with mobility impairments, such as those using wheelchairs, necessitating additional measures. WO 2014 / 1154758 A1 illustrates a toilet space with a transfer seat to facilitate transfer from a wheelchair to the commode seat. The increasing importance of toilet access for passengers with mobility impairments has been demonstrated. Furthermore, there is a need for further optimization of cabin space available for passenger seating. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a space-saving sanitary unit with a toilet seat, which provides improved comfort for people with mobility impairments.

[0004] This objective is achieved through a cabin module for an aircraft, an aircraft, a method for creating a cabin module for an aircraft, and the use of the cabin module in the aircraft. It should be noted that the aspects described below for the cabin module also apply to the aircraft, the method, and the use.

[0005] According to the present invention, a cabin module for an aircraft is provided. The cabin module has a sanitary unit designed with a toilet space equipped with a toilet. The toilet space is formed by four side walls, and the toilet is arranged on a first side wall. A first entrance door is arranged in a second side wall, which extends laterally to and connects to the first side wall. A space is provided within the toilet space, the space being designed to at least partially accommodate a wheelchair. The cabin module is configured for installation with the second side wall laterally to the flight direction. The first side wall, in the installed state, is oriented towards the outer wall.

[0006] The horizontal placement of the entrance door relative to the toilet seat results in a space-saving entry arrangement. The turning motion required for the user to use the toilet is less compared to a toilet space where the entrance door is positioned opposite the toilet seat. This horizontal entry relative to the toilet seat translates to improved user comfort.

[0007] In one example, a cabin module for an aircraft is provided. The cabin module has a sanitation unit designed with a toilet space equipped with a toilet. The toilet space is formed by four side walls, with the toilet arranged on a first side wall. A first entrance door is arranged in a second side wall, which extends laterally to and connects to the first side wall.

[0008] The aircraft is, for example, an airplane, preferably a passenger plane. The aircraft can also be a helicopter or a spacecraft.

[0009] The term "sanitation unit" refers to a space containing a toilet. A sanitation unit may also have a washbasin within the restroom space. Additionally, a sanitation unit may also have a urinal within the restroom space. The terms "lavatory" or "onboard lavatory" may also be used for sanitation units.

[0010] The sanitation unit is installed as a structural unit within the aircraft's cabin space. The cabin space is essentially formed, for example, by a floor incorporated into the fuselage, which divides the fuselage volume into a lower cargo or service area and an upper cabin area. For the cabin, the fuselage has an inner liner or cabin liner, thus forming the cabin space. The sidewalls of the sanitation unit connect to the cabin floor and the cabin liner. The cabin space can also be referred to as the cabin interior space.

[0011] The "cabin module" can also be referred to as the sanitation module. This cabin module contains a sanitation unit as its core component.

[0012] The sanitation unit is designed to be oriented or abutted against the interior of the fuselage with its first sidewall facing inward. Therefore, the toilet is designed so that, in its installed state, its orientation is transverse to the longitudinal axis of the aircraft.

[0013] The toilet has a direction of use oriented in the direction of its longitudinal central axis. The first entrance door is arranged in a side that extends substantially parallel to the direction of use, for example, parallel to the direction of use.

[0014] The term "direction of use" for a toilet refers to the central axis that is typically present in the toilet bowl and the toilet seat. It also refers to the orientation of the user when using the toilet in a seated position.

[0015] For example, the direction of use of the toilet forms an angle of up to 120°, or for example, up to 90°, with the vertical line of the second sidewall. In one instance, this angle is up to 80°.

[0016] In one example, the toilet is oriented transversely to the first sidewall. The toilet has, for example, a usage orientation transversely to the first sidewall.

[0017] In one example, the toilet is oriented from the first side wall toward the bathroom space. The toilet extends into the bathroom space, for example, from the first side wall.

[0018] The first entrance door forms the entrance to the bathroom space, which is transverse to the direction in which the toilet is used. In order to use the toilet while seated, the user must complete approximately 90° of rotation after entering the bathroom space.

[0019] For people with limited mobility, such as those who use wheelchairs, using a commode involves transferring from the wheelchair to the commode. This process is also known as the transfer process.

[0020] Passengers with reduced mobility are also referred to as PRMs (passengers with reduced mobility). For example, specialized wheelchairs are used on airplanes, designed to fit the confined space of the cabin. These wheelchairs are also known as OBWCs (On-board Wheelchairs).

[0021] Through the entrance that is transverse to the direction of use of the toilet, wheelchair users can reach the toilet space and then only need to complete a rotation of about 90°.

[0022] Even in situations where the bathroom space itself is narrow, the first entrance door can be made slightly wider than the front entrance. For example, an entrance door that is approximately 24 inches wide can be provided instead of a door that is approximately 20 inches wide, meaning that it is easier for people in wheelchairs to enter.

[0023] Wheelchair users can thus access the restroom space using their wheelchairs. For example, the wheelchair can be pushed into the restroom space at least partially or completely. By placing the wheelchair directly next to the toilet, transverse to the direction of use, the user only needs to make an approximately 90° transfer from the wheelchair there. For cases where the wheelchair is only partially pushed into the restroom space, a curtain can be provided to separate the area where the wheelchair still extends from other cabin and aisle areas. This ensures necessary privacy for people with mobility impairments. For easier access, a wheelchair-accessible threshold with a low structural height can be provided, making it particularly easy to push the front wheels over the threshold.

[0024] The first entrance door can also be referred to as the primary entrance door. The second side wall forms the first entrance side with the first entrance door.

[0025] The term "entrance door" refers to the bathroom door. The term "door" can also be used instead of "entrance door".

[0026] Within the bathroom space, handles and / or surrounding railings can be provided near the washbasin, sink, toilet, and / or door for gripping purposes to facilitate movement.

[0027] According to one example, a second entrance door is arranged in a third side wall, which extends laterally to and connects to the second side wall. Alternatively, the restroom space can be directly connected to the passageway area via the second entrance door.

[0028] When a person with limited mobility (PRM) uses the toilet, a second entrance door forms, for example, an entrance for assistive personnel.

[0029] For people with mobility impairments, they can be categorized according to the degree of their impairment:

[0030] - In the first category, the person is able to stand up from the wheelchair and turn to use the commode independently, and vice versa. The term "standing independent transfer" is also used for this category.

[0031] - In the second category, individuals can only stand up from their wheelchairs with assistance, i.e., help, and with assistance turn around and sit on the commode to use it, and vice versa. The term "standing assisted transfer" is also used for this category.

[0032] - In the third category, although the person cannot stand up from the wheelchair, they are able to independently perform a direct transfer from the wheelchair to the commode seat to use the commode, and vice versa. The term "seated independent transfer" is also used for this category.

[0033] - In category four, individuals can only perform direct transfer movements from a wheelchair to a commode seat to use the commode, and vice versa, with assistance. The term "seated-assisted transfer" is also used for this category.

[0034] In the version with a horizontally arranged entrance door, the sanitary unit is suitable for Categories 1 and 3. However, this version can also be used for Categories 2 and 4, because sufficient space can be designed for assistive workers within the toilet space through space-saving internal devices, such as angled washbasins.

[0035] In the version with an additional second entrance door, the sanitary unit is suitable for both Class 2 and Class 4. The second entrance allows for assistance from multiple sides. However, the version with the additional second entrance door is also suitable for Class 1 and Class 3.

[0036] In another instance, an overhead suspension system is provided to provide additional assistance to the passenger via a belt-driven seat assembly, which allows the passenger to be lifted vertically and moved laterally.

[0037] OBWC can be designed for transfer processes, for example, by having foldable handrails.

[0038] The third side wall and the second entrance door form the second entrance side. The third side wall is opposite to the first side wall.

[0039] The second entrance door can also be referred to as a secondary entrance door.

[0040] The fourth sidewall is connected to the third sidewall and also to the first sidewall. The fourth sidewall is opposite to the second sidewall.

[0041] For example, a washbasin assembly is provided on the fourth side wall.

[0042] The first and second entrance doors are located on two interconnected side walls that extend laterally to each other. One of these entrance doors is oriented laterally to the direction of use of the toilet, and the other of these entrance doors is oriented along the direction of use of the toilet.

[0043] For example, the second entrance door could be designed as a folding door.

[0044] The first and second entrance doors are arranged opposite each other at the corner.

[0045] In one example, the second and third sidewalls are connected at a corner via a connecting area. The cabin module has a connecting door that connects to the connecting area and is designed to separate the secondary entrance area from the passageway area located in front of it; that is, the secondary entrance area is located outside the lavatory space in front of the second entrance door.

[0046] The connecting door can also be called a third entrance door because it forms an entrance to the front area of ​​the toilet space. Since the front area is separated by the third entrance door and the toilet space can be accessed from the front area via the second door, people in the front area can assist toilet users with mobility issues. The toilet space can be temporarily expanded by using this switchable front area.

[0047] The connecting door, together with the second entrance door, forms a temporarily enlarged sanitary unit.

[0048] According to one example, a frame structure is provided, which connects to the bathroom space on a side opposite to a first sidewall. The frame structure is connectable to the primary structure of the body structure. The frame structure has at least two vertical structural elements forming a first frame side, which connects to a second sidewall, and the connecting door is disposed in the first frame side. At least a first entrance door and a connecting door are fixed to the frame structure.

[0049] Structural elements may be, for example, reinforced panels or reinforced profiles.

[0050] The frame has, for example, a horizontal connection, on the upper part. Alternatively or additionally, the horizontal connection is located on the lower part.

[0051] Frames and modules can be secured, for example, to ground-level systems, such as floor grids. Frames and modules can also be secured above, in the top area.

[0052] The frame structure connects to the third sidewall in the passage area, that is, in the entrance area.

[0053] According to one embodiment, the frame structure has four vertical structural elements that can be connected to a supporting structure and form four frame sides. A spatial region is formed between these four frame sides, connecting to a bathroom space and being separated from the bathroom space by a third sidewall. Optionally, a third sidewall is designed within the second frame region.

[0054] The frame structure has vertical, supporting struts that can be connected, for example, to the fuselage support structure to provide load transfer for doors with integrated flight attendant seats, for example, during use of the seats (using flight attendant seats).

[0055] Structural elements (also known as support elements) can be integrated into or implemented as reinforced wall sections to improve stability, thereby directing forces into the primary structure or diverting loads, such as the forces and loads of a crew seat.

[0056] The frame structure is an additional structure to the sanitary unit. The frame structure forms an extension to the sanitary unit and defines a front space that serves as an extension to the toilet space.

[0057] The walls of the sanitary unit are designed with joints that can accommodate tolerances and movement while still ensuring a tight seal. These joints are designed, for example, for areas with varying clearance sizes.

[0058] These connections are designed to cover any so-called system gaps that may exist, in order to enable the movement of modules relative to each other, especially that caused by deformation of the fuselage during flight.

[0059] According to one example, a cockpit door may be fixed in a third frame region arranged opposite to the first frame region. As an option, a fourth frame region is provided, arranged opposite to the second frame region, where a partition wall relative to the galley can be fixed. The fourth frame region can also form the partition wall itself.

[0060] According to one example, when the toilet space and entrance area are not in use, the first entrance door and connecting door can be locked from the cockpit, and the toilet space can be accessed from the cockpit via the entrance area and the second entrance door.

[0061] Therefore, even without opening the cockpit entrance from the cabin area, it is possible to reach the toilet from the cockpit. In other words, even when cockpit personnel are using the (passenger) toilet, the external entrance from the cabin to the cockpit remains uninterrupted, despite the cockpit door being open.

[0062] To address this, for example, space monitoring and a locking system with locking logic circuitry are provided. The space in front of the cockpit door can be seen through the peephole in the cockpit door. In one instance, sensors are installed to monitor the lavatory, providing information on whether the lavatory space is in use, in addition to a person / occupant indicator.

[0063] The first entrance door and connecting door can be locked from the cockpit so that the toilet can then be used. The second entrance door can also be locked from the cockpit.

[0064] According to one example, at least one of the group consisting of a first entrance door and a connecting door is designed with a flight attendant seat that can be temporarily used during flight.

[0065] Here, the flight attendant seat is designed to be integrated into the door, i.e., the seat is arranged within the door. For use, the seat surface can be flipped out. To transfer the load from both sides when using the flight attendant seat, for example, it is proposed that the door leaf where the flight attendant seat is arranged remains on both sides in the closed state, for example, on one side by a locking device extending in a certain area in terms of height and on the other side by a reinforced hinge; or by locking devices at multiple points distributed in height on both sides.

[0066] Flight attendant seats are available for use during takeoff and landing, when all passengers are (must) have fastened their seatbelts and the use of the lavatory is not permitted. Flight attendant seats may also be used during turbulence, when the use of the lavatory is similarly prohibited. Flight attendant seats are also known as CAS (Cabin Attendant Seat).

[0067] According to the present invention, an aircraft is also provided, the aircraft having a fuselage region and a cabin interior space arranged within the fuselage region. The cabin interior space has a cabin module according to one of the above embodiments. The aircraft has a longitudinal axis oriented toward the flight direction; and a second sidewall of the lavatory space extends transversely to the longitudinal axis of the aircraft.

[0068] According to one example, the aircraft has a first fuselage door on the port side, which is located in the forward region between the cockpit and the area with passenger seats, forming a forward boarding and disembarking gate for cabin interior space. A sanitation unit is located next to the boarding and disembarking gate.

[0069] The sanitation units are located adjacent to (i.e., right next to) the boarding and disembarking gates. The boarding and disembarking gates are also referred to as Exit A, and the sanitation spaces are also referred to as Washroom A.

[0070] The sanitation unit is located, for example, in front of the boarding and disembarking gates when viewed from the flight direction, that is, to the left of the boarding and disembarking gates when boarding on the port side.

[0071] One example proposes a partition section (viewed from the boarding direction) to the right of the boarding and disembarking gates, which is designed with a flight attendant seat available during takeoff and landing, as well as during flight. The flight attendant seat can be visually separated from the aisle area and the area of ​​the primary entrance door to the lavatory space by a movable spatial partition element, such as a curtain.

[0072] In another instance, it is proposed that, alternatively or additionally (viewed from the boarding direction), another flight attendant seat be arranged next to the first entrance door on the wall of the sanitation unit to the left of the boarding and disembarking gate.

[0073] The design of a restroom with an entrance door arranged horizontally to the direction of use can also be used on existing passenger aircraft without requiring major modifications to the fuselage.

[0074] According to one example, a boarding / disembarking area is provided inside the first fuselage door, and the first entrance door opens toward the boarding / disembarking area.

[0075] According to one example, the cabin interior includes a passenger seating assembly arranged on either side of a central aisle. Alternatively, flight attendant seats are integrated into the connecting door, oriented opposite to the direction of flight. These flight attendant seats are arranged to align with the central aisle, allowing occupants seated in them to see the aisle.

[0076] The center-positioned flight attendant seat near the auxiliary door allows for a clear view of the cabin during takeoff and landing, for example, on aircraft with only a central aisle along the cabin, where the seat rows extend to the left and right from that central aisle. The center-positioned flight attendant seat is also known as a direct-view CAS (Cross-Side Cabin Crew Seat). The center-positioned flight attendant seat is also usable when there are no passengers with mobility impairments using the lavatory space or when a second entrance door is not required.

[0077] Aside from takeoff and landing, the aircraft can also be observed while it is moving on the airport tarmac. These three periods are also known as TTL (Taxi, Takeoff, Landing).

[0078] In other words, the passenger seating components in the cabin interior have multiple rows, each row containing multiple seats, wherein the first part of the seat extends from the outer wall to the central aisle and the second part of the seat extends from the central aisle to the outer wall.

[0079] This component has only a middle channel as the vertically oriented channel and is also known as a Single-Aisle Configuration, in which only one channel area is provided.

[0080] In one example, a floor flap is arranged in the ground area of ​​the secondary entrance area to provide a temporary entrance to the rest cubicle located below.

[0081] According to the present invention, a method for creating a cabin module for an aircraft is also provided. The method comprises the following steps:

[0082] a) Provide a sanitary unit with a toilet space, the toilet space having a toilet;

[0083] The bathroom space is formed by four side walls;

[0084] b) A toilet is installed on the first side wall; and

[0085] c) A first entrance door is arranged in a second sidewall, the second sidewall extending laterally to and connected to the first sidewall.

[0086] A space is provided within the restroom area, designed to at least partially accommodate a wheelchair. The cabin module is configured for installation with the second sidewall transverse to the direction of flight. The first sidewall, in its installed state, is oriented towards the outer wall.

[0087] In one instance, a method for creating cabin modules for an aircraft is provided.

[0088] The method comprises the following steps:

[0089] a) Provide a sanitary unit with a toilet space, the toilet space having a toilet;

[0090] The bathroom space is formed by four side walls;

[0091] b) A toilet is installed on the first side wall; and

[0092] c) A first entrance door is arranged in a second sidewall, the second sidewall extending laterally to and connected to the first sidewall.

[0093] According to the present invention, the use of a cabin module in an aircraft according to one of the above examples is also provided.

[0094] According to one aspect of the invention, the toilet space has a door arranged transversely to the direction of the toilet seat arranged in the toilet space to ensure easy access for a wheelchair user. An option of a second door allows the toilet space to be temporarily expanded, for example, for assistance provided by a helper.

[0095] As an option, a combination of a lateral, i.e., horizontally arranged entrance door and an additional (entrance) door is provided.

[0096] As an option, a combination of a side-facing, i.e., laterally arranged door and a flight attendant seat integrated therein is provided.

[0097] As an alternative, a combination of a lateral, i.e., transversely arranged entrance door and a frame is provided, which is used to secure the lateral entrance door with integrated crew seats.

[0098] As an alternative, a combination of a lateral, i.e., transversely arranged door and an additional (entrance) door and frame is provided, which encloses the front area in front of the second entrance door and is used to secure the door with the crew seat.

[0099] It should be noted that the features of the module embodiments also apply to the implementation of the aircraft and the method, and vice versa. Furthermore, the following features can be freely combined with each other, even if not explicitly mentioned in these features.

[0100] These and other aspects of the invention can be seen by referring to and referring to the following embodiments. Attached Figure Description

[0110] Figure 9 A partial view of the cabin interior space of another example is shown.

[0111] Figure 10 The steps of an example of a method for creating a cabin module for an aircraft are illustrated schematically. Detailed Implementation

[0112] Figure 1The cabin module 10 of the aircraft is shown. The cabin module 10 has a sanitation unit 12. The sanitation unit 12 is designed with a toilet space 14, which includes a toilet 16. The toilet space 14 is formed by four side walls, indicated by reference numeral 18. The toilet 16 is located on a first side wall 18a. A first entrance door 20 is located in a second side wall 18b, which extends laterally to and connects to the first side wall 18a. Optionally, a space is provided within the toilet space 14, designed to at least partially accommodate a wheelchair. The cabin module 10 is configured for installation with the second side wall 18b laterally to the direction of flight. The first side wall 18a is oriented towards the outer wall in the installed state.

[0113] Figure 2 Another example of cabin module 10 is shown, wherein a second entrance door 22 is arranged in a third sidewall 18c, which extends transversely to and is connected to the second sidewall 18b.

[0114] Figure 3 An example of cabin module 10 is shown, wherein, as an option, the second sidewall 18b and the third sidewall 18c are connected at a corner via a connecting area 24. Cabin module 10 has a connecting door 26 that connects to the connecting area 24 and is designed to separate a secondary entrance area 28 from a passageway area located outside the lavatory space 14 in front of the second entrance door 22. This passageway area can be formed, for example, between the sanitation unit 12 and the galley module 30 (shown in dashed lines) and is limited at the left end of the figure by a cockpit door 32.

[0115] Figure 4 An example of the cabin module 10 is shown, in which a frame structure 34 is provided as an option, which connects to the lavatory space 14 on the side opposite the first sidewall 18a. The frame structure 34 can be connected to the primary structure of the fuselage structure. Vertical structural elements are provided for this purpose, which are indicated by reference numeral 36.

[0116] In one option, the frame structure 34 has at least two vertical structural elements 36a and 36b forming a first frame side 38a, which is connected to a second sidewall 18b and disposed in a connecting door 26. The first entrance door and the connecting door 26 are fixed to the frame structure 34.

[0117] In another, also Figure 4In the example shown as an option, frame structure 34 has four vertical structural elements 36 that are connectable to the supporting structure and form four frame sides, indicated by reference numeral 38 and shown in dashed lines. A space region 40 is formed between the vertical structural elements, which connects to the toilet space 14 and is separated from the toilet space by a third side wall 18c and a second entrance door 22.

[0118] As an option, a third sidewall 18c is designed in the second frame region 38b.

[0119] In another, also Figure 4 In the example shown as an option, a cockpit door 42 may be fixed in a third frame region 38c arranged opposite to the first frame region 38a, the cockpit door leading to the cockpit 44 to the left of the cockpit door 42 in the figure.

[0120] In another, also Figure 4 In the example shown as an option, a fourth frame region 38d is provided, which is arranged opposite to the second frame region 38b and is designed to be relative to the partition wall 46 of the onboard kitchen 48 or another space unit or use unit, or such partition wall can be fixed at the fourth frame region.

[0121] In an option not shown further, when the toilet space 14 and the entrance area 40 are free, i.e., unused, the first entrance door 20 and the connecting door 26 can be locked from the cockpit 44. Thus, the toilet space 14 can be accessed from the cockpit 44 via the entrance area 40 and the second entrance door 22.

[0122] Figure 5 The following is shown as an option: the door can be fitted with a flight attendant seat 50 integrated into the door panel, which can be temporarily used during flight. For example, a first flight attendant seat 50a is provided at the first entrance door 20. As an alternative or additional variant, a second flight attendant seat 50b is designed at the connecting door 26. (The terms "first," "second," etc., are used for naming purposes only and do not imply the total number of flight attendant seats present.)

[0123] exist Figure 5 As an example, a washbasin 52 with a washbasin 54 is shown. The washbasin 54 can be arranged at an angle to face a person in front of the toilet. Here, the washbasin 54 extends into an area, for example, near the toilet 16, so that the space in front of the toilet is only minimally affected by the extended washbasin.

[0124] The foot area under the washbasin can be flexible depending on the width of the module, allowing for more comfortable standing near the washbasin. Furthermore, the area under the washbasin can also serve as foot space for the PRM (Personal Reliable Wheelchair), enabling the wheelchair to be placed as fully as possible in narrow bathrooms and facilitating ergonomic PRM movement. Since wheelchairs typically have a footrest (protruding forward beyond the front wheels and resting on the feet, also tilted forward), the free area under the washbasin allows for further movement of the wheelchair into the bathroom space. Therefore, this free area can have a corresponding free height from the ground.

[0125] A washbasin is also provided as an option for other instances of washbasins not shown in the figure.

[0126] Rectangle 56 represents a wheelchair, such as an OBWC (On-board Wheelchair). The wheelchair passes through the first entrance door 20 from the right side (in the diagram) to reach the restroom space 14. The user is now able to perform the transfer movement from the wheelchair to the toilet 16.

[0127] In cases where a passenger in a wheelchair requires assistance, an assistive person can reach the entrance area 40 via connecting door 26 and reach the person in the wheelchair via the second entrance door 22.

[0128] exist Figure 5 As an alternative, a ground flap 58 (shown in dashed lines) is arranged in the ground area of ​​the secondary entrance area 28 or space area 40 to provide personnel with a temporary entrance to descend to the rest compartments located below.

[0129] As an option, in Figure 5 (and Figure 7 As shown in the diagram, the aircraft has a first fuselage door 60, which is arranged on the port side in the forward region between the cockpit 44 and the area with passenger seats (see...). Figure 9 This forms boarding and disembarking gates 62 for the interior space of the cabin. The fuselage structure with the outer skin is indicated by reference numeral 61. A sanitation unit 12 is arranged beside the boarding and disembarking gates 62. For example, a boarding / disembarking area 64 is provided on the side of the first fuselage door 60 facing the cabin, from which passengers enter a longitudinal or central aisle. The opening of the first entrance door 20 of the onboard lavatory is directed toward the boarding / disembarking area 64.

[0130] Here, the first entrance door 20 is pivoted in such a way that it is impossible for people to run and collide with the front of the door in the outward escape direction. A similar pivoting direction can, for example, also provide a way to connect door 26 and the second entrance door 22.

[0131] These doors (i.e., the first entrance door 20, the second entrance door 22, and the connecting door 26) are further arranged so that they open "outward" from the lavatory space 14 or connecting area 24 in the direction of passenger escape, i.e., in the direction of escape. The cockpit door 42 is also capable of opening in the direction of escape toward the connecting area.

[0132] As an option, in Figure 5 As shown, (viewed from the boarding direction) a wall section 66 is arranged to the right of the boarding and disembarking gate 62, which is designed with a third flight attendant seat 50c, which is available during takeoff and landing as well as during flight. The third flight attendant seat 50c is at least visually separated from the aisle area and the area of ​​the first entrance door 20 of the lavatory space 14 by a movable space divider 68, such as a curtain.

[0133] Alternatively or additionally, another, namely a fourth crew seat 50d, can be arranged on the opposite side, which is located in the area of ​​the first side wall 18b next to the first entrance door 20.

[0134] Figure 6 A schematic overview of a frame-type submodule is shown, having a frame 70 with a first side 72, an upper region 74, a second side 76, and a lower region 78. A first half 80a and a second half 80b are provided within the frame 70. A first door 82a is provided in the first half 80a, forming a first entrance door 20 to the restroom space. A second door 82b is provided in the second half 80b, forming a connecting door 26. The first door 82a is designed with an integrated first attendant seat 84a, and the second door 82b is designed with an integrated second attendant seat 84b.

[0135] Frame 70 extends partially through the restroom space area 86 and the passageway area 88, the restroom space area forming restroom space 14 and the passageway area forming connecting area 24. The partition wall between the two areas is indicated by dashed line 90. Frame 70 can be said to replace part of the wall structure of the restroom space. Frame 70 forms a reinforcement at which the two doors with the flight attendant seats can be stopped. When the doors are closed and the flight attendant seats are in use, the frame provides the necessary support for the forces generated by the use of the flight attendant seats.

[0136] Therefore, the holding points at the supporting structures can be formed more strongly.

[0137] To secure different sub-modules or components such as sanitary units, frames, or kitchen modules (also known as aircraft kitchen modules), lower fixing points or holding points 92a, 92b, 92c, 92d, 92e can be provided, for example, for securing to holding rails or fixing points in the ground structure.

[0138] To secure different sub-modules or components such as sanitary units, frames, or kitchen modules, upper fixing points or retaining points 94a, 94b, 94c, 94d, 94e, 94f, and 94g can also be provided, for example, for securing to retaining rails or fixing points in the top structure.

[0139] For example, the sanitary unit (washroom) is fixed to the ground structure by four anchor points and to the ceiling structure by other anchor points. Figure 6 Not all of them are shown, but only the lower fixing point 92a and, as examples, the upper fixing points 94a and 94g and the upper fixing point 94f in the lateral fuselage area, at which, for example, a rod element can establish a connection upward to the upper fuselage area.

[0140] The frame is secured to the ground and top structures, for example, by means of other anchor points, which are independent of the anchor points of the sanitary unit. Figure 6 The document does not show all of them, but only, for example, the lower fixing points 92b, 92c, and 92d and the upper fixing points 94b, 94c, and 94d. The upper fixing points can be connected upwards to the fuselage structure, for example, via rod-shaped pull / push elements.

[0141] It should be pointed out that, Figure 6 Only schematic illustrations are shown, in which the lateral ramps of the sanitary unit are not shown, for example, due to the arched structure of the fuselage.

[0142] The lavatory unit can be secured at four points below. The lavatory unit, or restroom, can be secured at one or two points above the fuselage in the center, because, for example, although the flight attendant seats are located at the doors leading to the lavatory unit, these doors remain in the frame, which is secured separately from the lavatory unit. The frame reduces the structural load on the lavatory unit. The frame is reinforced to bear additional loads downwards and upwards, defined by the flight attendant seats.

[0143] The frame is also detached from the sanitary unit at the lower point, i.e., the frame is decoupled.

[0144] The frame, for example, spans two spatial units, namely a sanitary unit and a front passageway or front area, which is located between the sanitary unit and a kitchen unit positioned opposite the longitudinal axis. The frame can be said to cut off a portion of the wall section of the two adjacent spaces, or more precisely, to replace the wall section in an area where the frame itself (with a door) forms a corresponding wall section.

[0145] The remaining wall sections, for example in Figure 6 The right wall leading to the galley area can be correspondingly fixed. Connections can be provided between the wall section and the frame module, which can, for example, cause decoupling of the relative movement between the module or sub-module and the cabin wall.

[0146] A doorpost 96 is provided at the sanitary unit for the second entrance door 22. This doorpost is arranged decoupled from the frame 70 and serves to accommodate the latch of the second entrance door 22 (not shown). The doorpost 96... Figure 6 It can be said that the partition wall 90, located behind the area between the two doors 82a and 82b and forming the partition wall between the bathroom space area 86 and the passageway area 88, is the rear end of the partition wall when viewed from the direction of flight.

[0147] In one variation, the frame is proposed to be only half the width and extends only beyond the doorway. Thus, another door is laterally stopped at the frame. For example, the frame can be positioned only in the area of ​​passageway 88. Thus, the second door 82a is positioned inside the frame, and the first door is laterally and movably fixed to the frame.

[0148] Figure 7 The rearward-biased arrangement of the cockpit door 42 in the flight direction is shown as an option.

[0149] Figure 8 An example of an aircraft 100 is shown, having an interior cabin space 104 arranged within a fuselage region 102, the interior cabin space having a cabin module 106, which is designed as one of the examples of cabin module 10. The aircraft 100 has a longitudinal axis 108 oriented toward the direction of flight. A second sidewall 18b of a lavatory space 14 extends transversely to the longitudinal axis 108 of the aircraft 100.

[0150] Figure 9One option is shown, in which the cabin interior space 104 is provided with a component 120 of passenger seats 122, which are arranged on both sides of the central aisle 124. For example, it is proposed that a flight attendant seat 50, such as a second flight attendant seat 50b, is integrated into the connecting door 26, and its seat position is opposite to the direction of flight, i.e., facing the tail. The flight attendant seat 50 is arranged to align with the central aisle 124, so that the person seated in the flight attendant seat can see the central aisle 124, as indicated by the viewing angle symbol 126. This facilitates uninterrupted visual inspection during takeoff and landing.

[0151] Figure 10 A method 200 for creating a cabin module for an aircraft is shown. Method 200 comprises the following steps:

[0152] - In step 202, also known as step a), a sanitary unit with a toilet space is provided, which includes a toilet. The toilet space is formed by four side walls.
