Description

TECHNICAL FIELD

[0001] Examples of the present disclosure generally relate to lavatories within an interior cabin of a vehicle, such as a commercial aircraft. BACKGROUND

[0002] Commercial aircraft are used to transport passengers between different locations. A typical commercial aircraft includes one or more lavatories within an interior cabin.

[0003] Space within a commercial aircraft is limited. Notably, lavatories within a commercial aircraft are typically relatively small in order to reduce the space of the lavatory and increase the space for other areas, such as passenger seats. Larger lavatories necessarily take up more space within a commercial aircraft and can prevent additional passenger seats within the interior cabin. Aircraft operators generally prefer to have additional passenger seats within the interior cabin as additional passenger seats increase revenue.

[0004] A typical lavatory within an aircraft interior cabin generally takes up about 20-30% more longitudinal area (i.e., area extending along and / or parallel to a longitudinal axis) of the interior cabin than a seat assembly. Generally speaking, current lavatories generally displace between six and twelve passenger seats. Certain interior cabins can be rearranged to ensure that only six passenger seats are displaced, but as a result, can have a cascading effect on surrounding interior features, such as other monuments or areas within the interior cabin. Overall, including a lavatory within the interior cabin of a commercial aircraft, while generally necessary, reduces the space within the interior cabin for other components, monuments, etc., such as revenue-generating seats.

[0005] Furthermore, people with limited mobility (e.g., people with disabilities, injuries, or reduced mobility) can find it relatively difficult to maneuver within the limited space of a commercial aircraft lavatory. These people can have difficulty moving within the lavatory, such as between the entrance and the toilet, and between the toilet and the sink.

[0006] Accordingly, certain manufacturers have designed larger lavatories that are specifically designed for people with limited mobility. However, in expanding the size of the lavatory, space within the interior cabin for other components, such as passenger seats, is necessarily reduced. SUMMARY

[0007] There is a need for a lavatory system within an interior cabin of a vehicle that includes multiple lavatory units that take up less space than known lavatories. There is a need for a lavatory system that includes multiple lavatory units that take up less space than an equivalent number of individual lavatories. Furthermore, there is a need for a lavatory system that is easily and easily accessible to people with limited mobility. Furthermore, there is a need for a multiple-unit lavatory system that does not reduce the space within an interior cabin of a vehicle for additional seats.

[0008] In view of these needs, certain examples of the present disclosure provide a lavatory system within an interior cabin of a vehicle. The lavatory system includes an enclosure defining an interior chamber, a first lavatory unit within the interior chamber, and a second lavatory unit within the interior chamber. The first lavatory unit is adjacent to the second lavatory unit. In at least one example, the enclosure is a single monument within the interior cabin. As an example, the first lavatory unit and the second lavatory unit span a portion of the interior cabin side-by-side. As an example, the first lavatory unit is inward of the second lavatory unit within the interior cabin, and the second lavatory unit is outward of the first lavatory unit within the interior cabin.

[0009] In at least one example, the enclosure includes a first end wall. An interior side wall is connected to the first end wall. The interior side wall faces a walkway of the interior cabin. A second end wall is connected to the interior side wall. The second end wall is opposite the first end wall. The second end wall faces an exit path of the interior cabin. An exterior side wall is connected to the first end wall and the second end wall.

[0010] In at least one example, the second end wall includes a first wall segment parallel to the first end wall and perpendicular to the interior side wall. An angled wall segment is angled toward the first end wall and the exterior side wall. A transition wall segment is connected to the angled wall segment. The transition wall segment is parallel to the interior side wall and the exterior side wall. A second end wall segment is connected to the transition wall and the exterior side wall. The second end wall segment is parallel to the first end wall. In at least one example, the exterior side wall is part of an exterior side wall of the interior cabin.

[0011] In at least one example, the first lavatory unit includes a first passageway connected to the walkway of the interior cabin. A first door is configured to open and close the first passageway. The second lavatory unit includes a second passageway connected to the exit path of the interior cabin. A second door is configured to open and close the second passageway.

[0012] In at least one example, the first lavatory unit has a first length and the second lavatory unit has a second length. The first length is greater than the second length.

[0013] In at least one example, the lavatory system further includes a dividing wall within the interior chamber. The dividing wall separates the first lavatory unit from the second lavatory unit. In at least one example, the dividing wall is movable between a closed position, which divides the interior chamber into the first lavatory unit and the second lavatory unit, and an open position, which provides an increased, expanded single lavatory space within the interior chamber.

[0014] The first lavatory unit includes a first sink and a first toilet and / or urinal. The second lavatory unit includes a second sink and a second toilet.

[0015] In an example, the lavatory system further includes a barrier movably coupled to one of the first lavatory unit or the second lavatory unit. The barrier is movable between an extended position and a retracted position. The barrier, in the extended position, is disposed forward of an exit door of the vehicle. The exit door is visible within the interior cabin when the barrier is in the retracted position. The barrier can include a handle configured to be grasped to move the barrier between the extended position and the retracted position. The barrier can include a sign indicating a location of one or both of the first lavatory unit or the second lavatory unit.

[0016] In at least one example, the lavatory system further includes a storage compartment extending outwardly from an outer wall of one or both of the first lavatory unit or the second lavatory unit. The storage compartment defines an interior storage space connected to the interior cabin. For example, the storage compartment is at least a portion of a luggage rack assembly. As another example, the storage compartment is at least a portion of an end cap connected to the luggage rack assembly.

[0017] A storage access door can be disposed between the storage compartment and the interior cabin. The storage access door is configured to move between an open position and a closed position. The interior storage space is open to the interior cabin when the storage access door is in the open position. The interior storage space is closed to the interior cabin when the storage access door is in the closed position. In at least one example, the storage compartment is directly connected to the interior cabin, but not within the interior cabin.

[0018] An access opening connects the interior storage space to the interior cabin. The access opening can be formed through the outer wall.

[0019] The storage compartment can include a lighting assembly positioned within the interior storage space. For example, the lighting assembly can be operably coupled to the storage access door of the storage compartment. The lighting assembly is configured to activate to illuminate the interior storage space when the storage access door is open. The lighting assembly is configured to deactivate when the storage access door is closed.

[0020] In at least one example, the lavatory system further includes a containment compartment common to the first lavatory unit and the second lavatory unit. For example, the containment compartment extends through a dividing wall separating the first lavatory unit from the second lavatory unit.

[0021] In at least one example, the containment compartment includes a first interior end wall within the first lavatory unit, a front wall, a rear wall, a base, an upper counter, and a second interior end wall opposite the first interior end wall. The second interior end wall is within the second lavatory unit. The first interior end wall, the front wall, the rear wall, the base, the upper counter, and the second interior end wall define a containment chamber of the containment compartment. A trash receptacle can be stored within the containment compartment.

[0022] In at least one example, the containment compartment further includes an access door within one of the first lavatory unit or the second lavatory unit. The access door is movable between an open position and a closed position. When the access door is in the open position, the containment compartment is exposed. When the access door is in the closed position, the containment compartment is closed.

[0023] In at least one example, the lavatory system further includes a first trash can opening in the first lavatory unit. The first trash can opening leads to the containment chamber of the containment compartment. A second trash can opening is in the second lavatory unit. The second trash can opening leads to the containment chamber of the containment compartment. As another example, a first trash can conduit is connected to the first trash can opening and a second trash can conduit is connected to the second trash can opening.

[0024] Certain examples of the present disclosure provide a method of forming a lavatory system within an interior cabin of a vehicle. The method includes providing a housing defining an interior chamber, forming a first lavatory unit within the interior chamber, and forming a second lavatory unit within the interior chamber. The first lavatory unit is adjacent to the second lavatory unit.

[0025] Certain examples of the present disclosure provide a vehicle including an interior cabin having an aisle and an exit path, and a lavatory system within the interior cabin as described herein.

[0026] Certain examples of the present disclosure provide a lavatory within an interior cabin of a vehicle. The lavatory includes an interior chamber defined by one or more exterior walls and a storage compartment extending outwardly from at least one of the exterior walls. The storage compartment defines an interior storage space connected to the interior chamber. The lavatory can be at least one lavatory unit of a lavatory system.

[0027] As an example, the storage compartment is at least a portion of a luggage rack assembly. As another example, the storage compartment is at least a portion of an end cap connected to the luggage rack assembly.

[0028] The lavatory can further include a storage access door disposed between the storage compartment and the interior chamber. The storage access door is configured to move between an open position and a closed position. When the storage access door is in the open position, the interior storage space is open to the interior chamber. When the storage access door is in the closed position, the interior storage space is closed to the interior chamber.

[0029] In at least one example, the storage compartment is directly connected to the interior chamber, but the storage compartment is not within the interior chamber.

[0030] As an example, an access opening connects the interior storage space to the interior chamber. The access opening is formed through the one or more exterior walls.

[0031] The storage compartment can include a lighting assembly within the interior storage space. The lighting assembly is operably coupled to a storage access door of the storage compartment. For example, the lighting assembly is configured to activate to illuminate the interior storage space when the storage access door is opened. The lighting assembly is configured to deactivate when the storage access door is closed.

[0032] Certain examples of the present disclosure provide a method of forming a lavatory within an interior cabin of a vehicle. The method includes defining an interior chamber of the lavatory by one or more exterior walls, extending a storage compartment outward from at least one of the exterior walls, and connecting an interior storage space of the storage compartment to the interior chamber.

[0033] Certain examples of the present disclosure provide a vehicle including an interior cabin and a lavatory within the interior cabin of the vehicle as described herein.

[0034] Certain examples of the present disclosure provide a lavatory system within an interior cabin of a vehicle. The lavatory system includes a first lavatory unit, a second lavatory unit adjacent to the first lavatory unit, and a containment compartment common to the first lavatory unit and the second lavatory unit.

[0035] In at least one example, the containment compartment extends through a dividing wall separating the first lavatory unit from the second lavatory unit.

[0036] As an example, the containment compartment includes a first interior end wall within the first lavatory unit, a front wall, a rear wall, a base, an upper counter, and a second interior end wall opposite the first interior end wall. The second interior end wall is within the second lavatory unit. The first interior end wall, the front wall, the rear wall, the base, the upper counter, and the second interior end wall define a containment cavity of the containment compartment. A trash receptacle container is storable within the containment compartment.

[0037] In at least one example, the containment compartment includes an access door within one of the first lavatory unit or the second lavatory unit. The access door is movable between an open position and a closed position. The containment compartment is exposed when the access door is in the open position. The containment compartment is closed when the access door is in the closed position.

[0038] In at least one example, a first trash receptacle opening is in the first lavatory unit. The first trash receptacle opening is open to the containment cavity of the containment compartment. A second trash receptacle opening is in the second lavatory unit. The second trash receptacle opening is open to the containment cavity of the containment compartment. As another example, a first trash receptacle conduit is connected to the first trash receptacle opening, and a second trash receptacle conduit is connected to the second trash receptacle opening.

[0039] Certain examples of the present disclosure provide a method of forming a lavatory system within an interior cabin of a vehicle. The method includes providing a containment compartment common to a first lavatory unit and a second lavatory unit adjacent to the first lavatory unit.

[0061] The foregoing summary, as well as certain examples, will be better understood when read in conjunction with the following detailed description. As used herein, an element or step recited in the singular and preceded by the word "a" or "an" should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to "one example" are not intended to be interpreted as excluding the existence of additional examples that also incorporate the recited features. Additionally, unless specifically stated otherwise, examples using terms such as "comprise", "have" or "include" shall not be construed as excluding the presence of additional elements or steps.

[0062] Certain examples of the present disclosure provide a lavatory system that includes two lavatory units within a common enclosure, such as a single common building. The lavatory units are arranged to replace only a single three-seater assembly unit. In at least one example, the lavatory system is located near the last and exit door of a row of seats. In comparison to traditional lavatories within a commercial aircraft, the lavatory system allows an aircraft operator to have four lavatories (two lavatories per lavatory system) within an area, while at the same time preserving up to eighteen passenger seats. Accordingly, examples of the present disclosure provide a lavatory system that allows an aircraft operator to maintain or even increase revenue-generating passenger seats within an interior cabin.

[0063] Figure 1A perspective front view of an aircraft 10 is shown in accordance with examples of the present disclosure. The aircraft 10 includes a propulsion system 12 including, for example, engines 14. Optionally, the propulsion system 12 can include more engines 14 than shown. The engines 14 are carried by a wing 16 of the aircraft 10. In other examples, the engines 14 can be carried by a fuselage 18 and / or a tail 20. The tail 20 can also support a horizontal stabilizer 22 and a vertical stabilizer 24.

[0064] The fuselage 18 of the aircraft 10 defines an interior cabin 30 including a flight deck or cockpit, one or more crew areas (e.g., a galley, a crew rest area, etc.), one or more passenger areas (e.g., first class, business class, and economy class), one or more lavatory areas, etc. As described herein, the interior cabin 30 includes one or more lavatory systems, lavatory units, or lavatories.

[0065] Alternatively, instead of an aircraft, examples of the present disclosure can be used with various other vehicles, such as automobiles, buses, locomotives and rail cars, watercraft, etc. Further, examples of the present disclosure can be used with fixed structures, such as commercial and residential buildings.

[0066] Figure 2A A top plan view of an interior cabin 30 of an aircraft is shown in accordance with examples of the present disclosure. The interior cabin 30 can be within a fuselage 32 (e.g., the fuselage 18 of the aircraft 10) of the aircraft. For example, one or more fuselage walls can define the interior cabin 30. The interior cabin 30 includes multiple sections, including a forward section 33, a first class section 34, a business class section 36, a forward galley station 38, an expanded economy or coach section 40, a standard economy or coach section 42, and an aft section 44, which can include multiple lavatories and galley stations. It should be understood that the interior cabin 30 can include more or fewer sections than shown. For example, the interior cabin 30 can not include a first class section, and the interior cabin can include more or fewer galley stations than shown. Each section can be separated by a cabin transition area 46, which can include a level separation assembly between aisles 48. Figure 1

[0067] As shown, the interior cabin 30 includes two aisles 50 and 52 leading to the aft section 44. Optionally, the interior cabin 30 can have fewer or more aisles than shown. For example, the interior cabin 30 can include a single aisle that extends through the center of the interior cabin 30 and then leads to the aft section 44. Figure 2A

[0068] The aisles 48, 50, and 52 extend to an exit path or doorway 60. An exit door 62 is located at the end of the exit path 60. The exit path 60 can be perpendicular to the aisles 48, 50, and 52. The interior cabin 30 can include more exit paths 60 than shown at different locations. As described herein, a lavatory system can be located at or near the intersection of the aisles 48, 50, 52 and the exit path 60. ​​

[0069] Figure 2B A top plan view of the interior cabin 80 of an aircraft according to an example of this disclosure is shown. Interior cabin 80 is... Figure 1 An example of an interior cabin 30 is shown. The interior cabin 80 may be located within the fuselage 81 of the aircraft. For example, one or more fuselage walls may define the interior cabin 80. The interior cabin 80 comprises multiple sections, including a main cabin 82 with passenger seats 83 and a tail section 85 aft of the main cabin 82. It should be understood that the interior cabin 80 may include more or fewer sections than shown.

[0070] The interior compartment 80 may include a single passageway 84 leading to the aft section 85. The single passageway 84 may extend through the center of the interior compartment 80 and then lead to the aft section 85. For example, the single passageway 84 may be coaxially aligned with the central longitudinal plane of the interior compartment 80.

[0071] The passageway 84 extends to an exit path or doorway 90. An exit door 92 is located at the end of the exit path 90. The exit path 90 may be perpendicular to the passageway 84. The interior compartment 80 may include more exit paths than shown. As described herein, a lavatory system may be located at or near the intersection of the passageway 84 and one or more exit paths 90.

[0072] Figure 3 A perspective interior view of the cabin 100 of an aircraft according to an example of this disclosure is shown. The cabin 100 is as follows: Figure 1 An example of interior cabin 30 is shown. Interior cabin 100 includes an outer wall 102 connected to a ceiling 104. Windows 106 may be formed within the outer wall 102. A floor 108 supports multiple rows of seats 110. Figure 3 As shown, row 112 may include two seats 110 on either side of aisle 113. However, row 112 may include more or fewer seats 110 than shown. Additionally, interior cabin 100 may include more aisles than shown.

[0073] A passenger service unit (PSU) 114 is fixed on either side of aisle 113 between outer wall 102 and ceiling 104. The PSU 114 extends between the front and rear ends of interior cabin 100. For example, the PSU 114 may be positioned above each seat 110 in row 112. Each PSU 114 may include a housing 116 that typically contains vents, reading lights, oxygen bag holders, crew request buttons, and other such controls above each seat 110 (or group of seats) in row 112.

[0074] Overhead luggage rack assemblies 118 are secured to the ceiling 104 and / or outer sidewall 102 above and inboard of the PSU 114 on either side of the aisle 113. The overhead luggage rack assemblies 118 are secured above the seats 110. The overhead luggage rack assemblies 118 extend between the front and rear ends of the interior cabin 100. Each overhead luggage rack assembly 118 can include a pivot bin or tub 120 pivotally secured to a positioning plate (hidden from view in Figure 3 The overhead luggage rack assemblies 118 can be positioned above and inboard of the lower surface of the PSU 114. For example, to receive carry-on luggage and personal items of passengers, the overhead luggage rack assemblies 118 are configured to pivot open.

[0075] As used herein, the term "outboard" refers to a location further from the center longitudinal plane 122 of the interior cabin 100 than another component. The term "inboard" refers to a location closer to the center longitudinal plane 122 of the interior cabin 100 than another component. For example, the lower surface of the PSU 114 can be outboard relative to the luggage rack assemblies 118.

[0076] Figure 4 A perspective interior view of a lavatory 130 within an interior cabin of a vehicle, such as any of the interior cabins described herein, is shown. The lavatory 130 is an example of an enclosed space, building, or chamber within the interior cabin of the aircraft 10 shown, for example. Figure 1 As described above, the lavatory 130 can be on an aircraft. Alternatively, the lavatory 130 can be on various other vehicles. In other examples, the lavatory 130 can be within a fixed structure, such as a commercial or residential building. The lavatory 130 includes a base floor 131 that supports a toilet 132 (and / or urinal), a cabinet 134, and a sink 136 or wash basin. The lavatory 130 can be arranged differently than shown. The lavatory 130 can include more or fewer components than shown.

[0077] Figure 5 A top view of a lavatory system 150 within an interior cabin 152 is shown, in accordance with examples of the present disclosure. The lavatory system 150 can be used within any of the interior cabins described herein, such as the interior cabin described with respect to Figure 1 to Figure 3 the lavatory system 150 shown and described.

[0078] The lavatory system 150 includes a single enclosure 154 (e.g., a building) that includes a first lavatory unit 156 adjacent to a second lavatory unit 158. That is, the lavatory system 150 is a single building. The first lavatory unit 156 and the second lavatory unit 158 are disposed laterally across a portion of the interior cabin 152, rather than longitudinally along the aisle 160. That is, the first lavatory unit 156 and the second lavatory 158 span across a portion of the interior cabin 152 side-by-side, rather than end-to-end along the length of the interior cabin 152. In this manner, the lavatory system 150 extends over a smaller longitudinal portion of the interior cabin 152 (e.g., one longitudinal region 162), rather than over an elongated longitudinal portion (e.g., two longitudinal regions (e.g., if the first lavatory unit 156 and the second lavatory unit 158 were disposed end-to-end)), freeing up additional space for other components (e.g., another building (e.g., a galley) or additional passenger seating (e.g., three seat assemblies)), which generates revenue for the aircraft operator.

[0079] The lavatory system 150 provides two lavatory units (such as the first lavatory unit 156 and the second lavatory unit 158) while replacing only a single seat assembly having three passenger seats. For example (as opposed to lavatories disposed end-to-end), the side-by-side configuration of the first lavatory unit 156 and the second lavatory unit 158 provides multiple lavatory units while allowing for additional passenger seating. In at least one example, the lavatory system 150 provides multiple lavatory units within the space of a three seat unit passenger seat assembly.

[0080] The first lavatory unit 156 is an inboard lavatory unit, while the second lavatory unit 158 is an outboard lavatory unit. It should be understood that the terms first and second are merely for labeling purposes. The first lavatory unit can be the second lavatory unit, and vice versa.

[0081] The single enclosure 154 (e.g., building) defining the lavatory system 150 includes a first end wall 164 (or first system end wall) connected to an interior side wall 166 (or system interior side wall) facing the aisle 160. The interior side wall 166 is connected to a second end wall 168 (or second system end wall) opposite the first end wall 164. The second end wall 168 faces an egress path 170 connected to the aisle 160. In at least one example, the second end wall 168 includes a first wall segment 172 that can be parallel to the first end wall 164 (and perpendicular to the interior side wall 166). The first wall segment 172 is connected to a sloped wall segment 174 that is sloped toward the first end wall 164 and an exterior side wall 176 (or system exterior side wall) connected to the first end wall 164 and the second end wall 168. The sloped wall segment 174 is, in turn, connected to a transition wall segment 176 that can be parallel to the interior side wall 166 and an exterior side wall 178. The transition wall segment 178 is connected to a second wall segment 180 that can be parallel to the first end wall 164 and perpendicular to the exterior side wall 176. Optionally, without the transition wall segment 178, the sloped wall segment 174 can be directly connected to the second wall segment 180. The second wall segment 180 is connected to the exterior side wall 178.

[0082] In at least one example, the exterior side wall 176 is part of an exterior side wall (e.g., the exterior side wall 102 shown) of the interior cabin 152. That is, the exterior side wall 102 partially defines the interior cabin 152. Using part of the exterior side wall of the interior cabin 152 to provide the exterior side wall 176 provides increased interior space within the lavatory system 150. In at least one other example, the exterior side wall 176 is a separate wall in close proximity to or otherwise proximate to the exterior side wall of the interior cabin 152. Figure 3

[0083] The first end wall 164, the interior side wall 166, the second end wall 168, and the exterior side wall 176 define an outer perimeter of the enclosure 154 (and the building 155) and an interior chamber 182 of the lavatory system 150. That is, the enclosure 154 defines the interior chamber 182. The enclosure 154 is within the interior cabin 152. The enclosure 154 is not the interior cabin 152. For example, the interior cabin can include multiple lavatories. However, the interior cabin 152 includes the enclosure 154 that includes the first lavatory unit 156 and the second lavatory unit 158 within the interior chamber 182 of the enclosure 154 (as opposed to two different lavatories that are abutting one another). The enclosure 154 includes the first lavatory unit 156 and the second lavatory unit 158 within the interior chamber 182. The first lavatory unit 156 and the second lavatory unit 158 are within the interior chamber 182.

[0084] ​The first lavatory unit 156 includes a passageway 184 connected to the corridor 160. A door 186 is movably coupled to the first end wall 164 and / or the interior side wall 166. The door 186 faces the corridor 160 and is configured to move between a closed position in which the passageway 184 is closed to the corridor 160 and an open position in which the passageway 184 is open to the corridor 160. When the door 186 is in the open position, a person can pass between the corridor 160 and the first lavatory unit 156 through the passageway 184.

[0085] The second lavatory unit 158 includes a passageway 188 connected to the exit path 170. A door 190 is movably coupled to the second end wall 168, such as the second wall segment 180 and / or the exterior side wall 176. The door 190 faces the exit path 170 and is configured to move between a closed position in which the passageway 188 is closed to the exit path 170 and an open position in which the passageway 188 is open to the exit path 170. When the door 190 is in the open position, a person can pass between the exit path 170 and the second lavatory unit 158 through the passageway 188.

[0086] In at least one example, the length 192 of the first lavatory unit 156 is greater than the length 194 of the second lavatory unit 158. For example, the first lavatory unit 156 can extend a greater length along the longitudinal length of the corridor 160 than the second lavatory unit 158. As a result, the second wall segment 180 including the passageway 188 of the second lavatory unit 158 can be further recessed toward the first end wall 164 than the first wall segment 172.

[0087] A dividing wall 196 is disposed within the interior chamber 182 and extends between the first end wall 164 and the second end wall 168. The dividing wall 196 separates the first lavatory unit 156 from the second lavatory unit 158. The dividing wall 196 can include a first dividing segment 198 that can be perpendicular to the first end wall 164. The first dividing segment 198 is connected to a sloped dividing segment 200 that is sloped toward the interior side wall 166 and the first wall segment 172. The sloped dividing segment 200 is connected to a second dividing segment 202 that can be parallel to the first dividing segment 198. The second dividing segment 202 can be connected to the transition wall segment 178 and / or another portion of the second end wall 168.

[0088] In at least one example, the first lavatory unit 156 is defined between the inboard sidewall 166, the first wall segment 172, the sloped wall segment 174, the transition wall segment 178, the first side 204 of the partition wall 196, and the inboard segment 165 of the first end wall 164 (i.e., the portion from the inside of the partition wall 196). The second lavatory unit 158 is defined between the outboard sidewall 176, the outboard segment 167 of the first end wall 164 (i.e., the portion from the outside of the partition wall 196), the second side 206 of the partition wall 196 (opposite the first side 204), and the second wall segment 180 of the second end wall 168.

[0089] The first lavatory unit 156 includes a first sink 208 and a first toilet 210, and has a first standing space 212 in front of the first toilet 210. The first sink 208 can be located at or near a corner 209 defined by the first side 204 of the partition wall 196 and the inboard segment 165 of the first end wall 164. The first toilet 210 can be located at or near a corner 211 defined by the inboard sidewall 166 and the second end wall 168. The term toilet as used herein includes one or both of a standard toilet or a urinal.

[0090] The second lavatory unit 158 includes a second sink 214 and a second toilet 216, and has a second standing space 218 in front of the second toilet 216. The second sink 214 can be located at or near a corner 213 defined by the second side 206 of the partition wall 196 and the second wall segment 180 of the second end wall 168. The second toilet 216 can be located at or near a corner 215 defined by the outboard sidewall 176 and the outboard segment 167 of the first end wall 164.

[0091] Figure 5 The sink and toilet configuration of the first lavatory unit 156 and the second lavatory unit 158 shown is merely exemplary. The sinks and toilets can be located in various other areas than shown.

[0092] In at least one example, an attendant assistance space 220 is positioned in front of the second wall segment 180 of the second end wall 168 (e.g., in front of the passageway 188). The attendant assistance space 220 can be near the last exit door of the exit path 170. The attendant assistance space 220 is an open area in which an attendant can stand to assist people entering and exiting the exit path 170. The second lavatory unit 158 is sized and configured to preserve a defined required area (e.g., a 12” x 20” area) for the attendant assistance space, such as an area that can be required by a regulatory agency (e.g., the Federal Aviation Administration). The sloped wall segment 174 can provide an exit flow director that directs and guides people toward the exit door when exiting the in-cabin 152, and toward the aisle 160 when entering the in-cabin 152.

[0093] Figure 6 A top view of a lavatory system 150 within an interior cabin 152 is shown according to an example of the present disclosure. In this example, a first sink 208 of a first lavatory unit 156 can be coupled to a first side 204 of a dividing wall 196 at a mid-point between a first end wall 164 and a second end wall 168, and a second sink 214 can be coupled to an outer side wall 176. Figure 6 The configuration of the sinks and toilets of the first lavatory unit 156 and the second lavatory unit 158 shown is merely exemplary. The sinks and toilets can be located in various other areas than shown.

[0094] Figure 7 A top view of a lavatory system 150 within an interior cabin 152 is shown according to an example of the present disclosure. Figure 7 The lavatory system 150 shown in Figure 5 the lavatory system shown in , except that the dividing wall 196 can be configured to move between a closed position, in which the dividing wall separates the interior room 182 into defined first and second lavatory units 156, 158, and an open position, in which the interior room 182 provides an increased, expanded single lavatory space that a person with limited mobility can easily and comfortably enter. The first sink 208, the first toilet 210, the second sink 214, and the second toilet 216 can not be connected to the movable portion of the dividing wall 196. For example, the dividing wall 196 can include multiple foldable segments 230 coupled together by hinges 232 that allow the dividing wall 196 to be folded and disconnected from one or both of the first and second end walls 166, 168. In this way, the dividing wall 196 is foldable or otherwise collapsible. The dividing wall 196 in the collapsed position can be secured against an interior wall, and / or can be removed and stored within the lavatory system 150 or another portion of the interior cabin 152. As another example, the dividing wall 196 can be configured to telescope between the open and closed positions. As another example, the dividing wall 196 can be configured to slide between the open and closed positions. As another example, the dividing wall 196 can be a window shade or drape that can include a sound dampening component. In short, the dividing wall 196 can be a movable wall having segments configured to move so as to allow the dividing wall 196 to move between the open and closed positions.

[0095] Figure 8 A top view of a lavatory system 150 within an interior cabin 152 is shown according to an example of the present disclosure. Figure 8 The lavatory system 150 shown in Figure 6 is similar to Figure 7The dividing wall 196 can be configured to move between a closed position, in which the dividing wall separates the interior cabin 182 into defined first and second lavatory units 156, 158, and an open position, in which the interior cabin 182 provides an increased, expanded single lavatory space that is easily and comfortably accessible by a person with limited mobility.

[0096] Figure 19 A top view of a lavatory system 150 within an interior cabin is shown in accordance with examples of the present disclosure. In this example, the lavatory system 150 includes a dividing wall 196 having one or more sliding or telescoping segments 197.

[0097] Referring to Figure 5 to Figure 8 and Figure 19 The lavatory system 150 allows the space of three passenger seats to be occupied by two lavatory units. Conventional lavatories occupy approximately 20% to 30% more longitudinal space than a passenger seat, resulting in six to twelve passenger seats being displaced in order to install two lavatories. Conventional lavatory area sizes are in the range of 10.8 to 13.4 square feet. In contrast, the lavatory system 150 as described herein provides two lavatory units, for example, within a thirteen square foot area, which can be the same or similar area of a single three-passenger seat assembly (60” x 32”).

[0098] In at least one example, the lavatory system 150 can be located at the end of a row of seats near an exit door. The second (or outboard) lavatory unit 158 opens into the exit path 170, for example, a lateral exit passageway into a reserved space used by flight attendants during emergency evacuations (during which time the lavatory is not used). The first (or inboard) lavatory unit 156 opens into the aisle 160 or, optionally, into the same exit path 170. Alternatively, the first lavatory unit 156 can extend longitudinally further than the second lavatory unit 158, as the first lavatory unit 156 is inboard of the flight attendant aid space 220.

[0099] Figure 9 A perspective view of a lavatory system 150 near an exit door 260, for example, of an aircraft, is shown in accordance with examples of the present disclosure. The exit door 260 is located at the end of the exit path 170. Alternatively, the lavatory system 150 can include a movable barrier 262 movably coupled to the second lavatory unit 158. The barrier 262 can be a panel, wall, screen, door, curtain, etc., configured to move between an extended position, as shown, in which the barrier 262 is disposed in front of the exit door 260, and a retracted position, in which the exit door 260 is visible within the interior cabin 152. Figure 9

[0100] ​Barrier 262 may be movably connected to the second lavatory unit 158, another part of the lavatory system 150, or a part of the interior compartment, such as via hinges, slides, and tracks. For example, barrier 262 is configured to pivot, for example, about one or more hinges, between an extended position and a retracted position. As another example, barrier 262 is configured to slide between an extended position and a retracted position. As yet another example, barrier 262 is configured to unfold and fold between an extended position and a retracted position.

[0101] When passengers enter and exit cabin 152, for example, through exit door 260 in the open position to exit path 170, barrier 262 is in the retracted position. During flight, barrier 262 moves to the extended position, such as... Figure 9 As shown. In the extended position, barrier 262 conceals exit door 260 or at least a portion of it (e.g., handle 264), protecting exit door 260 from being touched and ensuring that there is no risk of someone accidentally grabbing handle 264.

[0102] Figure 10 A front view of a barrier 262 in an extended position, according to an example of this disclosure, is shown. The barrier 262 may include a handle 270 that can be gripped to move the barrier 262 between an extended position and a retracted position. The barrier 262 may also include a marker 272 indicating the location of a second washroom unit 158 ​​(e.g., Figure 9 (As shown), especially because the door of the second washroom unit 158 ​​can be hidden from view by an extension of the first washroom unit 156. The sign 272 can be painted or printed on the barrier 262. As another example, the sign 272 can be a decal. As another example, the sign 272 can be a plate or panel mounted on the barrier 262. As another example, the sign 272 can be illuminated, for example, by one or more light components.

[0103] Barrier 262 may be used with any of the lavatory systems 150 described herein. Alternatively, lavatory system 150 may not include barrier 262.

[0104] Figure 11 An example of connection to an overhead luggage rack assembly 304 (such as...) according to this disclosure is shown. Figure 3 The diagram shows a perspective view of the lavatory 300 of the row 302 of the luggage rack assembly 118. As described herein, the lavatory 300 may be a lavatory system 150. For example, as... Figure 5 to Figure 9 As shown, washroom 300 may be a second washroom unit 156. As another example, washroom 300 may be a single-unit washroom, whether or not it is part of the washroom system 150 described herein.

[0105] A portion of the row 302 is directly connected to the lavatory 300, for example, to a front end or a rear end of the lavatory 300. For example, the luggage rack assembly 304 can be directly connected to the lavatory 300, such as at the upper portion 306 of the lavatory 300. As another example, an end cap 308 of the row 302 connects the luggage rack assembly 304 to the lavatory 300.

[0106] The end cap 308 and / or the luggage rack assembly 304 provide a storage compartment 310 that extends outward from an outer wall 312 of the lavatory 300, for example, at an upper overhead portion that is aligned with the luggage rack assembly 304. The storage compartment 310 defines an interior storage space 314 that is connected to an interior chamber 316 of the lavatory 300. One or more outer walls, including the outer wall 312, define the interior chamber 316. The storage compartment 310 extends outward from the one or more outer walls. That is, the storage compartment 310 is not within the interior chamber 316. In this way, the storage compartment 310 can replace one or more cabinets that would otherwise be within the lavatory 300, freeing up additional space within the lavatory 300.

[0107] A movable compartment or a storage access door can be provided between the storage compartment 310 and the interior chamber 316 of the lavatory 300. The storage access door can be movable between an open position, in which the interior storage space 314 is open to the interior chamber 316, and a closed position, in which the interior storage space is closed to the interior chamber 316. Various supplies, such as toilet paper, facial tissue, and the like, can be stored within the interior storage space 314, rather than within the interior chamber 316 of the lavatory 300.

[0108] As shown, the storage compartment 310 is directly connected to the interior chamber 316 of the lavatory 300, but the storage compartment is not within the interior chamber 316. Rather, the storage compartment 310 can be part of the end cap 308 and / or the luggage rack assembly 304 that is outside of the interior chamber 316 of the lavatory 300. The interior storage space 314 of the storage compartment 310 can be accessed from within the interior chamber 316 of the lavatory 300. By recessing cabinet space into the end cap 308 and / or the overhead luggage rack assembly 304, more space is created within the interior chamber 316 that would otherwise be occupied by one or more cabinets. Generally, the storage compartment 310 that is coupled to the lavatory 300 reduces the need for cabinet space within the lavatory 300.

[0109] Figure 12 A perspective view of a storage compartment 310 extending outward from a lavatory 300 is shown in accordance with examples of the present disclosure. As described above, the storage compartment 310 can be at least part of an end cap coupled to a luggage rack assembly, or alternatively, at least part of a luggage rack assembly. An access opening 320 connects the interior storage space 314 of the storage compartment 310 to the interior chamber 316 of the lavatory 300. The access opening 320 can be formed through a wall 322, for example, a front wall or a rear wall, of the lavatory 300.

[0110] The storage access door 324 is movably coupled to the storage compartment 310 and / or the wall 322. The storage access door 324 is movable between an open position and a closed position. The storage access door 324 can pivot about one or more hinges, slide on one or more tracks, etc. between the open position and the closed position.

[0111] In at least one example, a lighting assembly 326 can be provided within the storage compartment 310. The lighting assembly 326 is configured to illuminate the interior storage space 314. In at least one example, the lighting assembly 326 is operably coupled to the storage access door 324, such as by a switch 328. In this way, the lighting assembly 326 can be activated to illuminate the interior storage space 314 when the storage access door 324 is open and deactivated when the storage access door 324 is closed.

[0112] The storage compartment 310 can be used with any of the examples described herein. For example, the storage compartment 310 can be connected to any of the lavatories or lavatory units described herein.

[0113] Figure 13 An interior perspective view of a containment compartment 300 for a first lavatory 302 connected to a second lavatory 304 according to examples of the present disclosure is shown. The lavatory system 301 includes the first lavatory 302, the second lavatory 304, and the containment compartment 300 that is common (e.g., shared) to both the first lavatory 302 and the second lavatory 304. The containment compartment 300 defines a containment chamber 303. In at least one example, for example, as shown and described with respect to Figure 5 to Figure 9 The first lavatory 302 is a first lavatory unit 156 and the second lavatory 304 is a second lavatory unit 158, for example, as shown and described with respect to

[0114] The first lavatory 302 is separated from the second lavatory 304 by a dividing wall 306. The dividing wall 306 can be a dividing wall 196, for example, as shown and described with respect to Figure 5 to Figure 9

[0115] The first lavatory 302 includes a first housing 308 (e.g., a first cabinet) and the second lavatory 304 includes a second housing 310 (e.g., a second cabinet). The containment compartment 300 is common to both the first lavatory 302 and the second lavatory 304. The containment compartment 300 extends through the dividing wall 196.

[0116] ​The containment compartment 300 includes a first interior end wall 312 connected to a front wall 314, a rear wall 316, a base 318, and an upper counter 320 that extend between and / or form part of the first housing 308 and the second housing 310. The front wall 314, the rear wall 316, the base 318, and the upper counter 320 are connected to a second interior end wall 322 opposite the first interior end wall 312. The first interior end wall 312 is within the first washroom 302, and the second interior end wall 322 is within the second washroom 304. The first interior end wall 312 can be part of the first housing 308 (e.g., a first cabinet), and the second interior end wall 322 can be part of the second housing 310 (e.g., a second cabinet).

[0117] The first interior end wall 312, the front wall 314, the rear wall 316, the base 318, the upper counter 320 (which extends across the dividing wall 306), and the second interior end wall 322 define a containment chamber 303 of the containment compartment 300. The containment compartment 300 is shared by the first washroom 302 and the second washroom 304. The containment compartment 300 is shared by both the first washroom 302 and the second washroom 304.

[0118] The trash receptacle 330 is configured to be stored within the containment compartment 300. An access door 332 is coupled to the front wall 314, e.g., within the first washroom 302. For example, the access door 332 is movably coupled to the front wall 312 within the first washroom 302 (or, optionally, the second washroom 304). The access door 332 is movably connected to the front wall 314, e.g., by one or more hinges, slides, tracks, and the like. Thus, the access door 332 is configured to be pivotally or slidably movable between an open position, in which the containment chamber 303 of the containment compartment 300 is exposed, and a closed position, in which the containment chamber 303 of the containment compartment 300 is closed. The trash receptacle 330 is selectively removable and repositionable when the access door 332 is in the open position.

[0119] A first trash receptacle opening 340 having a movable lid 341 is formed in the upper counter 320 within the first washroom 302. A second trash receptacle opening 342 having a movable lid 343 is formed in the upper counter 320 within the second washroom 304. Both the first trash receptacle opening 340 and the second trash receptacle opening 342 open into the containment chamber 303 of the containment compartment 300, which is shared by both the first washroom 302 and the second washroom 304. In this way, trash placed in both the first washroom 302 and the second washroom 304 can be discarded through the respective first trash receptacle opening 340 and second trash receptacle opening 320 into the trash receptacle 330 disposed within the containment chamber 303 of the containment compartment 300.

[0120] In at least one example, the containment compartment 300 can be configured to contain a fire therein. For example, the interior wall portions defining the containment compartment 300 can be formed of a fire-resistant material, and the interface between the wall and the access door 332 in the closed position can be sealingly engaged with one another to limit the flow of oxygen into the containment compartment 300 when the access door 332 is closed. Further, the containment compartment 300 can hold a fire suppression device 350, such as a fire extinguisher, that is shared by the first and second lavatories 302, 304.

[0121] The containment compartment 300 holds the trash receptacle 330 that is used by both the first and second lavatories 302, 304, thereby saving space for both the first and second lavatories 302, 304. In this way, additional space is provided for both the adjacent first and second lavatories 302, 304. The containment compartment 300 provides access to the single trash receptacle 330 from both the separate but adjacent lavatories 302, 304 that are separated by the partition wall 306.

[0122] The containment compartment 300 can be used with any of the examples described herein. For example, the containment compartment 300 can be used with respect to any adjacent lavatory or lavatory unit as described herein.

[0123] Figure 14 A simplified front view of the containment compartment 300 that is shared by the first and second lavatories 302, 304 is shown in accordance with an example of the present disclosure. The containment compartment 300 extends through the partition wall 306 such that a first portion 300a of the containment compartment 300 is within the first lavatory 302 and a second portion 300b of the containment compartment 300 is within the second lavatory 304.

[0124] In at least one example, a first container portion 330a of the trash receptacle 330 is below the first trash receptacle opening 340 and a second container portion 330b of the trash receptacle 330 is below the second trash receptacle opening 342. Accordingly, trash that enters and passes through the first and second trash receptacle openings 340, 342 is received in the containment chamber 331 of the trash receptacle 330.

[0125] Figure 15 A simplified front view of the containment compartment 300 that is shared by the first and second lavatories 302, 304 is shown in accordance with an example of the present disclosure. The trash receptacle 330 can not be positioned directly below the first and / or second trash receptacle openings 340, 342. Accordingly, a first trash receptacle conduit 350 can be connected to the first trash receptacle opening 340 and a second trash receptacle conduit 352 can be connected to the second trash receptacle opening 342. The first and second trash receptacle conduits 350, 352 open into the containment chamber 331 of the trash receptacle 330.

[0126] Figure 16 A flowchart of a method 400 of forming a lavatory system within an interior cabin of a vehicle is shown. The method 400 includes providing an enclosure defining an interior chamber at step 402, forming a first lavatory unit within the interior chamber at step 404, and forming a second lavatory unit within the interior chamber at step 406. The first lavatory unit is adjacent the second lavatory unit.

[0127] In at least one example, the step 406 of forming the second lavatory includes providing a portion of an exterior side wall of the interior cabin as an exterior side wall of the second lavatory.

[0128] In at least one example, the step 404 of forming the first lavatory unit includes connecting a first passageway of the first lavatory unit to an aisle of the interior cabin, and the step 406 of forming the second lavatory unit includes connecting a second passageway of the second lavatory unit to an exit path of the interior cabin.

[0129] In at least one example, the method includes providing a dividing wall within the interior chamber, and separating the first lavatory unit from the second lavatory unit with the dividing wall. As another example, the method can include moving the dividing wall between a closed position in which the dividing wall separates the interior chamber into the first lavatory unit and the second lavatory unit, and an open position in which the interior chamber provides an enlarged, expanded single lavatory space.

[0130] As another example, the method includes movably coupling a barrier to one of the first lavatory unit or the second lavatory unit, and moving the barrier between an extended position and a retracted position. The barrier in the extended position is disposed forward of an exit door of the vehicle. The exit door is visible within the interior cabin when the barrier is in the retracted position.

[0131] Optionally, the method includes providing a storage compartment extending outwardly from an exterior wall of one or both of the first lavatory unit or the second lavatory unit at step 408. The storage compartment defines an interior storage space connected to the interior chamber. As another option, the method includes the step 408 in relation to the lavatory system, lavatory, or lavatory unit, instead of the steps 402-406.

[0132] Optionally, the method includes providing a containment compartment common to the first lavatory unit and the second lavatory unit at step 410. As another option, the method includes the step 410 in relation to the lavatory system, lavatory, or lavatory unit, instead of the steps 402-408. As another option, the method includes the steps 408 and 410, but not the steps 402-406.

[0133] Figure 17A flowchart of a method 500 for forming a lavatory within the interior of a vehicle is shown. Method 500 includes: in step 502, defining an interior chamber of the lavatory by one or more outer walls; in step 504, extending a storage compartment outwardly from at least one of the outer walls; and in step 506, connecting the internal storage space of the storage compartment to the interior chamber.

[0134] In at least one example, the method includes forming at least a portion of the luggage rack assembly as a storage compartment. As another example, the method includes forming at least a portion of an end cap attached to the luggage rack assembly as a storage compartment.

[0135] In at least one example, the method includes: setting a storage access door positioned between a storage compartment and an inner chamber; and moving the storage access door, which moves between an open position and a closed position. When the storage access door is in the open position, the inner storage space is open to the inner chamber. When the storage access door is in the closed position, the inner storage space is closed to the inner chamber.

[0136] In at least one example, the extension includes connecting the storage compartment directly to the interior room. The storage compartment is not located within the interior room.

[0137] As an example, the method includes: an entrance / exit formed through one or more outer walls; and connecting the internal storage space to the interior room through the entrance / exit.
