Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to lavatories in the interior cabins of vehicles such as commercial aircraft.

Background Art

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

[0003] Space within a commercial aircraft is limited. In particular, lavatories within a commercial aircraft are generally relatively small in order to reduce the space of the lavatory and increase the space of other areas such as passenger seats. A large lavatory will necessarily take up more space within the commercial aircraft, potentially preventing the addition of passenger seats in the interior cabin. Aircraft operators typically prefer to add passenger seats in the interior cabin because adding passenger seats leads to an increase in revenue.

[0004] A typical lavatory within an aircraft's interior cabin generally occupies approximately 20% to 30% more of the longitudinal area of the interior cabin (i.e., the area extending along and / or parallel to the longitudinal axis) compared to a seat assembly. Generally, in order to accommodate a current lavatory, 6 to 12 passenger seats must be removed. In some interior cabins, it is possible to rearrange in order to have only 6 passenger seats removed. However, as a result, a chain effect will occur on the surrounding interior elements such as other monuments and areas within the interior cabin. Generally, including a lavatory within the interior cabin of a commercial aircraft is usually necessary, but it results in narrowing the space of other components and monuments within the interior cabin, such as seats that generate revenue.

[0005] Furthermore, individuals with limited mobility (e.g., people with disabilities, injuries, or reduced motor skills) may find it relatively difficult to move around in the confined space of a lavatory on a commercial aircraft. Such individuals may have difficulty moving within the lavatory, for example, between the entrance and the toilet, and between the toilet and the sink.

[0006] Therefore, some manufacturers design larger restrooms for people with limited mobility. However, increasing the size of the restroom inevitably reduces the space available for other components in the interior cabin (e.g., passenger seats). [Overview of the project]

[0007] Therefore, a restroom system is needed in the vehicle's interior cabin that includes multiple restroom units that take up less space than a known restroom. Furthermore, a restroom system is needed that includes multiple restroom units that take up less space than the same number of individual restrooms. Additionally, a restroom system is needed that is easily and readily accessible to persons with limited mobility. Finally, a multi-unit restroom system is needed in the vehicle's interior cabin that does not reduce space for additional seating.

[0008] With these needs in mind, in some embodiments of this disclosure, a restroom system in the interior cabin of a vehicle is provided. The restroom system includes a housing defining an interior chamber, a first restroom unit in the interior chamber, and a second restroom unit in the interior chamber. The first restroom unit is adjacent to the second restroom unit. In at least one example, the housing is a single monument within the interior cabin. As an example, the first restroom unit and the second restroom unit are arranged side by side across a portion of the interior cabin. As an example, the first restroom unit is located in the interior cabin on the machine side from the second restroom unit, and the second restroom unit is located in the interior cabin on the machine side from the first restroom unit.

[0009] In at least one example, the housing includes a first end wall. An interior wall is connected to the first end wall. The interior wall faces the passage of the interior cabin. A second end wall is connected to the interior wall. The second end wall is located on the opposite side from the first end wall. The second end wall faces the exit passage of the interior cabin. An exterior wall is connected to the first and second end walls.

[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 inner wall of the aircraft. An inclined wall segment is inclined toward the first end wall and the outer wall of the aircraft. A transition wall segment is connected to the inclined wall segment. The transition wall segment is parallel to the inner wall and the outer wall of the aircraft. A second end wall segment is connected to the transition wall and the outer wall of the aircraft. The second end wall segment is parallel to the first end wall. In at least one example, the outer wall of the aircraft is part of the outer wall of the interior cabin.

[0011] In at least one example, the first restroom unit includes a first entrance / exit connecting to a passage in the interior cabin. The first door is configured to open and close the first entrance / exit. The second restroom unit includes a second entrance / exit connecting to an exit passage in the interior cabin. The second door is configured to open and close the second entrance / exit.

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

[0013] In at least one example, the restroom system also includes a partition wall in the internal chamber. The partition wall separates the first restroom unit from the second restroom unit. In at least one example, the partition wall is movable between a closed position and an open position, in the closed position the internal chamber separates the first restroom unit from the second restroom unit, and in the open position the internal chamber provides a large, expanded single restroom space.

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

[0015] In one example, the restroom system also includes a barrier movably coupled to either the first restroom unit or the second restroom unit. The barrier is movable between an extended position and a retracted position. In the extended position, the barrier is positioned in front of the vehicle's exit door. When the barrier is in the retracted position, the exit door is visible from inside the interior cabin. The barrier may include a handle to be grasped for moving the barrier between the extended position and the retracted position. The barrier may include markings indicating the location of either or both of the first restroom unit or the second restroom unit.

[0016] In at least one example, the restroom system also includes a storage compartment extending outward from the outer wall of one or both of the first or second restroom units. The storage compartment defines an internal storage space connected to the internal chamber. For example, the storage compartment is at least part of a luggage rack assembly. In another example, the storage compartment is at least part of an end cap connected to a luggage rack assembly.

[0017] A storage access door may be provided between the storage compartment and the internal 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 internal storage space is open to the internal chamber. When the storage access door is in the closed position, the internal storage space is closed to the internal chamber. In at least one example, the storage compartment is directly connected to the internal chamber but is not located inside the internal chamber.

[0018] The internal storage space is connected to the internal chamber by an access opening. The access opening may be formed by penetrating the outer wall.

[0019] The storage compartment may include a lighting assembly within the internal storage space. For example, the lighting assembly may be functionally coupled to the storage access door of the storage compartment. The lighting assembly is configured to operate and illuminate the internal storage space when the storage access door is open. The lighting assembly is also configured to stop operating when the storage access door is closed.

[0020] In at least one example, the restroom system also includes a storage area common to the first restroom unit and the second restroom unit. For example, the storage area penetrates a partition wall separating the first restroom unit and the second restroom unit.

[0021] In at least one example, the storage compartment includes a first inner end wall, a front wall, a rear wall, a bottom surface, an upper counter, and a second inner end wall opposite to the first inner end wall within the first restroom unit. The second inner end wall is located within the second restroom unit. The first inner end wall, the front wall, the rear wall, the bottom surface, the upper counter, and the second inner end wall define the storage chamber of the storage compartment. A waste container is housed within the storage compartment.

[0022] In at least one example, the storage compartment also includes an access door to either the first or second restroom unit. The access door is movable between an open position and a closed position. When the access door is in the open position, the storage compartment is exposed. When the access door is in the closed position, the storage compartment is closed.

[0023] In at least one example, the restroom system also includes a first waste opening in the first restroom unit, which is connected to a storage chamber in the storage unit. The second restroom unit is provided with a second waste opening, which is connected to the storage chamber in the storage unit. In a further example, a first waste duct is connected to the first waste opening, and a second waste duct is connected to the second waste opening.

[0024] In some embodiments of this disclosure, a method is provided for forming a restroom system within the interior cabin of a vehicle. The method includes providing a housing that defines an interior chamber, forming a first restroom unit within the interior chamber, and forming a second restroom within the interior chamber. The first restroom unit is adjacent to the second restroom unit.

[Modes for carrying out the invention]

[0042] The above-described summary of the invention and the detailed descriptions of the specific embodiments shown below will be better understood when read in conjunction with the accompanying drawings. In this specification, elements or steps described in the singular form do not necessarily exclude multiple elements or steps. Furthermore, the reference to “one embodiment” is not intended to exclude the existence of other embodiments that incorporate the described features. Furthermore, unless otherwise specified, embodiments that “compile” or “have” one or more elements having a particular property may additionally include other elements that do not have that property.

[0043] In some embodiments of the present disclosure, a lavatory system is provided that includes two lavatory units within a common enclosure, such as a single common monument. The lavatory units are positioned to replace only a single three-seat assembly unit. In at least one example, the lavatory system is located at the end of a row of seats and near an exit. The lavatory system allows an aircraft operator to have four lavatory units in an area (two per lavatory system) and to retain as many as 18 passenger seats compared to conventional lavatory systems in commercial aircraft. Thus, embodiments of the present disclosure provide a lavatory system that enables an aircraft operator to maintain or increase the number of revenue-generating passenger seats in the interior cabin.

[0044] Figure 1 is a perspective front view showing an aircraft 10 according to one embodiment of the present disclosure. The aircraft 10 includes, for example, a propulsion system 12 with engines 14. Optionally, the propulsion system 12 may include more engines 14 than shown in the illustrated example. The engines 14 are mounted on the wings 16 of the aircraft 10. In other examples, the engines 14 may be mounted on the fuselage 18 and / or the tail 20. The tail 20 may also support a horizontal stabilizer 22 and a vertical stabilizer 24.

[0045] The fuselage 18 of the aircraft 10 defines an interior cabin 30, which includes a flight deck or cockpit, one or more work sections (e.g., a galley and a carry-on baggage area), one or more passenger sections (e.g., a first-class section, a business-class section, and a coach section), and / or one or more lavatories. As described herein, the interior cabin 30 includes one or more lavatory systems, lavatory units, or lavatories.

[0046] Instead of aircraft, embodiments of the present disclosure can be used with a variety of other vehicles, such as automobiles, buses, locomotives, trains, and ships. Furthermore, embodiments of the present disclosure may be used with fixed structures, such as commercial or residential buildings.

[0047] Figure 2A is a top view showing an interior cabin 30 of an aircraft according to one embodiment of the present disclosure. The interior cabin 30 may be located inside the fuselage 32 of an aircraft, such as the fuselage 18 shown in Figure 1. In one or more examples, the interior cabin 30 is defined by one or more fuselage walls. The interior cabin 30 includes several sections, such as a forward section 33, a first-class section 34, a business-class section 36, a forward galley station 38, an extended economy section 40, a standard economy section 42, and a rear section 44, which may include multiple lavatories and galley stations. The interior cabin 30 may include more or fewer sections than shown. In one or more examples, the interior cabin 30 may not include a first-class section and may include more or fewer galley stations than shown. Each of these sections is separated by a cabin partitioning area 46, which may include class partition assemblies between aisles 48.

[0048] As shown in Figure 2A, the interior cabin 30 includes two passages 50 and 52 that lead to the rear section 44. Optionally, the interior cabin 30 may include fewer or more passages than those shown in the illustration. In one or more examples, the interior cabin 30 may include a single passage that runs through the center of the interior cabin 30 and leads to the rear section 44.

[0049] Passages 48, 50, and 52 extend to an exit passage or door passage 60. Exit doors 62 are located at both ends of the exit passage 60. The exit passage 60 may be perpendicular to passages 48, 50, and 52. The interior cabin 30 may include more exit passages 60 at locations different from those shown in the illustration. As described herein, the restroom system may be located at or near the intersections of passages 48, 50, 52 and the exit passage 60.

[0050] Figure 2B is a top view showing an aircraft interior cabin 80 according to one embodiment of the present disclosure. The interior cabin 80 is an example of the interior cabin 30 shown in Figure 1. The interior cabin 80 may be located inside the fuselage 81 of the aircraft. In one or more examples, the interior cabin 80 is defined by one or more fuselage walls. The interior cabin 80 includes a main cabin 82 having passenger seats 83, and a rear section 85 behind the main cabin 82, among other sections. The interior cabin 80 may include more or fewer sections than shown in the example.

[0051] The interior cabin 80 may include a single passageway 84 leading to the rear section 85. The single passageway 84 may extend through the center of the interior cabin 80 leading to the rear section 85. For example, the single passageway 84 may be aligned coaxially with the central longitudinal plane of the interior cabin 80.

[0052] The passage 84 extends to an exit passage or door passage 90. Exit doors 92 are located at both ends of the exit passage 90. The exit passage 90 may be perpendicular to the passage 84. The interior cabin 80 may include more exit passages than those shown. As described herein, the restroom system may be located at the intersection of the passage 84 and one or more exit passages 90, or in close proximity to these intersections.

[0053] Figure 3 is a perspective interior view showing an aircraft interior cabin 100 according to one embodiment of the present disclosure. The interior cabin 100 is an example of the interior cabin 30 shown in Figure 1. The interior cabin 100 includes an exterior wall 102 connected to the ceiling 104. Windows 106 are formed in the exterior wall 102. The floor 108 supports rows of seats 110. As shown in Figure 3, a row 112 may include two seats 110 on each side of an aisle 113. Note that a row 112 may include more or fewer seats 110 than shown. In addition, the interior cabin 100 may include more aisles than shown.

[0054] On both sides of the aisle 113, passenger service units (PSUs) 114 are fixed between the outer wall 102 and the ceiling 104. The PSUs 114 are scattered between the front and rear ends of the interior cabin 100. For example, one PSU 114 may be provided above each seat 110 in a row 112. Each PSU 114 includes a housing 116 above each seat 110 (or seat group) in the row 112, the housing generally includes a vent, a reading light, an oxygen bag drop panel, a crew call button, and other similar control units.

[0055] The overhead luggage rack assemblies 118 are fixed to the ceiling 104 and / or the exterior walls 102 above and inside the PSU 114 on both sides of the aisle 113. The overhead luggage rack assemblies 118 are fixed above the seats 110. The overhead luggage rack assemblies 118 extend between the front and rear ends of the interior cabin 100. Each luggage rack assembly 118 may include a pivotable container / box 120 pivotably fixed to the strongback (hidden from view in Figure 3). The overhead luggage rack assemblies 118 may be located above the underside of the PSU 114 and inside the aircraft. The overhead luggage rack assemblies 118 are configured to pivot and open, for example, to receive passengers' hand luggage and personal belongings.

[0056] In this specification, the term "outboard" refers to a location that is farther from the central longitudinal surface 122 of the interior cabin 100 compared to other components. Conversely, the term "inboard" refers to a location that is closer to the central longitudinal surface 122 of the interior cabin 100 compared to other components. For example, the underside of the PSU 114 is located on the outboard side relative to the luggage rack assembly 118.

[0057] Figure 4 is a perspective interior view showing a restroom 130 in the interior cabin of a vehicle, such as one of the interior cabins described herein. The restroom 130 is an example of a sealed space, monument, or room, such as in the interior cabin of the aircraft 10 shown in Figure 1. As described above, the restroom 130 may be installed in an aircraft. Optionally, the restroom 130 may be installed in a variety of other vehicles. In other examples, the restroom 130 may be located in a fixed structure, such as a commercial or residential building. The restroom 130 includes a toilet 132 (and / or urinal), a cabinet 134, and a base floor 131 supporting a sink 136 or washbasin. The arrangement of the restroom 130 may differ from that shown. The restroom 130 may include more or fewer components than shown.

[0058] Figure 5 is a top view showing a lavatory system 150 in an interior cabin 152 according to one embodiment of the present disclosure. The lavatory system 150 can be used in any of the interior cabins described herein, such as the interior cabin described with reference to Figures 1 to 3.

[0059] The restroom system 150 includes a single enclosure 154 (e.g., a monument) which includes a first restroom unit 156 adjacent to a second restroom unit 158. In other words, the restroom system 150 is a single monument. The first restroom unit 156 and the second restroom unit 158 ​​are arranged laterally across a portion of the interior cabin 152, rather than longitudinally along the passageway 160. That is, the first restroom unit 156 and the second restroom unit 158 ​​are arranged side-to-side across a portion of the interior cabin 152, rather than end-to-end along the length of the interior cabin 152. In this embodiment, the lavatory system 150 extends into a shorter longitudinal section (e.g., a single longitudinal area 162) in the interior cabin 152, rather than into a long longitudinal section (e.g., two longitudinal areas (assuming the first lavatory unit 156 and the second lavatory unit 158 ​​are arranged longitudinally)), thereby freeing up space for other components such as other monuments (e.g., galleys) or for additional passenger seats (e.g., three-seat assemblies) that would generate revenue for the aircraft operator.

[0060] The restroom system 150 replaces only a single seating assembly having three passenger seats, while providing two restroom units, such as a first restroom unit 156 and a second restroom unit 158. The side-by-side configuration of the first and second restroom units 156 and 158 allows for the provision of multiple restroom units, while enabling, for example, the addition of passenger seats (as opposed to restrooms arranged in a vertical line). In at least one example, the restroom system 150 provides multiple restroom units within the space of a passenger seating assembly that is a three-seat unit.

[0061] The first lavatory unit 156 is an on-board lavatory unit, and the second lavatory unit 158 ​​is an on-board lavatory unit. The terms "first" and "second" are merely used as designations. The first lavatory unit may be the second lavatory unit, and vice versa.

[0062] A single enclosure (e.g., a monument) 154 defining the lavatory system 150 includes a first end wall 164 (i.e., a first system end wall) connected to an in-machine wall 166 (i.e., a system in-machine wall) facing a passageway 160. The in-machine wall 166 connects to a second end wall 168 (i.e., a second system end wall) opposite to the first end wall 164. The second end wall 168 faces the exit passageway 170, which connects to the passageway 160. In at least one example, the second end wall 168 includes a first wall segment 172 parallel to the first end wall 164 (and perpendicular to the in-machine wall 166). The first wall segment 172 connects to an inclined wall segment 174, which is inclined toward the first end wall 164 and toward an out-machine wall 176 (i.e., a system out-machine wall) connected to the first end wall 164 and the second end wall 168. The inclined wall segment 174 connects to a transition wall segment 176 that is parallel to the inner wall 166 and the outer wall 178 of the aircraft. The transition wall segment 178 connects to a second wall segment 180, which is parallel to the first end wall 164 and perpendicular to the outer wall 176 of the aircraft. Optionally, the inclined wall segment 174 may be directly connected to the second wall segment 180 without going through the transition wall segment 178. The second wall segment 180 connects to the outer wall 178 of the aircraft.

[0063] In at least one example, the outer wall 176 is part of the outer wall of the interior cabin 152, such as the outer wall 102 shown in Figure 3. That is, the outer wall 102 partially defines the interior cabin 152. By using part of the outer wall of the interior cabin 152 to form the outer wall 176, the space within the lavatory system 150 can be increased. In at least one other example, the outer wall 176 is a separate wall that is in contact with or adjacent to the outer wall of the interior cabin 152.

[0064] The first end wall 164, the inner wall 166, the second end wall 168, and the outer wall 176 define the outer perimeter of the housing 154 (and monument 155) and define the internal chamber 182 of the lavatory system 150. That is, the housing 154 defines the internal chamber 182. The housing 154 is located within the internal cabin 152. The housing 154 is not the internal cabin 152. For example, the internal cabin may include multiple lavatory units. However, the internal cabin 152 includes the housing 154, which includes a first lavatory unit 156 and a second lavatory unit 158 ​​within its internal chamber 182 (as opposed to the case where two different lavatory units are in contact with each other). The housing 154 includes the first lavatory unit 156 and the second lavatory unit 158 ​​within the internal chamber 182. The first restroom unit 156 and the second restroom unit 158 ​​are located within the internal chamber 182.

[0065] The first restroom unit 156 includes an entrance / exit 184 connected to the passageway 160. A door 186 is movably coupled to the first end wall 164 and / or the machine-side wall 166. The door 186 faces the passageway 160 and is configured to move between a closed position in which the entrance / exit 184 is closed to the passageway 160 and an open position in which the entrance / exit 184 is open to the passageway 160. When the door 186 is in the open position, a person can pass through the entrance / exit 184 between the passageway 160 and the first restroom unit 156.

[0066] The second restroom unit 158 ​​includes an entrance / exit 188 connected to the exit passage 170. A door 190 is movably coupled to the second end wall 168 (e.g., the second wall segment 180 and / or the machine-side wall 176). The door 190 faces the exit passage 170 and is configured to move between a closed position, where the entrance / exit 188 is closed to the exit passage 170, and an open position, where the entrance / exit 188 is open to the exit passage 170. When the door 190 is in the open position, a person can pass through the entrance / exit 188 between the exit passage 170 and the second restroom unit 158.

[0067] In at least one example, the length 192 of the first restroom unit 156 is longer than the length 194 of the second restroom unit 158. For example, the first restroom unit 156 extends longer along the longitudinal length of the passage 160 compared to the second restroom unit 158. Thus, the second wall segment 180, which includes the entrance 188 of the second restroom unit 158, may be recessed further toward the first end wall 164 compared to the first wall segment 172.

[0068] The internal chamber 182 is provided with a partition wall 196 that extends between the first end wall 164 and the second end wall 168. The partition wall 196 separates the first restroom unit 156 from the second restroom unit 158. The partition wall 196 may include a first partition segment 198 perpendicular to the first end wall 174. The first partition segment 198 is connected to an inclined partition segment 200 that slopes toward the machine-side wall 166 and the first wall segment 172. The inclined partition segment 200 is connected to a second partition segment 202 parallel to the first partition segment 198. The second partition segment 202 may be connected to the transition wall segment 178 and / or other parts of the second end wall 168.

[0069] In at least one example, a first lavatory unit 156 is defined between the aircraft-side wall 166, a first wall segment 172, an inclined wall segment 174, a transition wall segment 178, a first surface 204 of a partition wall 196, and the aircraft-side segment 165 of the first end wall 164 (i.e., the portion on the aircraft side from the partition wall 196). A second lavatory unit 158 ​​is defined between the aircraft-side wall 176, an aircraft-side segment 167 of the first end wall 164 (i.e., the portion on the aircraft side from the partition wall 196), a second surface 206 of the partition wall 196 (the surface opposite to the first surface 204), and a second wall segment 180 of the second end wall 168.

[0070] The first restroom unit 156 includes a first sink 208 and a first toilet 210, with a first standing space 212 provided in front of the first toilet 210. The first sink 208 may be located in or near a corner 209, which is defined by a first surface 204 of a partition wall 196 and an interior segment 165 of a first end wall 164. The first toilet 210 may be located in or near a corner 211, which is defined by an interior wall 166 and a second end wall 168. As used herein, the term “toilet” refers to one or both of a standard toilet or a urinal.

[0071] The second restroom unit 158 ​​includes a second sink 214 and a second toilet 216, with a second standing space 218 provided in front of the second toilet 216. The second sink 214 may be located in or near a corner 213, which is defined by the second surface 206 of the partition wall 196 and the second wall segment 180 of the second end wall 168. The second toilet 216 may be located in or near a corner 215, which is defined by the outer wall 176 and the outer segment 167 of the first end wall 164.

[0072] The configurations of the sinks and toilets in the first restroom unit 156 and the second restroom unit 158 ​​shown in Figure 5 are merely illustrative. The sinks and toilets can be installed in various areas different from those shown.

[0073] In at least one example, a cabin crew assist space 220 is provided in front of the second wall segment 180 of the second end wall 168, such as in front of the entrance 188. The cabin crew assist space 220 may be close to an exit door at the end of the exit path 170. The cabin crew assist space 220 is an open area from which cabin crew can stand to assist people entering and exiting the exit path 170. The second lavatory unit 158 ​​is sized and configured to maintain a specified required area for the cabin crew assist space (e.g., a 12-inch x 20-inch area) as required by a regulatory body (e.g., the U.S. Federal Aviation Administration). The sloping wall segment 174 may form an egress flow director that guides and directs people toward the exit door when exiting the interior cabin 152 and toward the aisle 160 when entering the interior cabin 152.

[0074] Figure 6 is a top view showing a restroom system 150 in an internal cabin 152 according to one embodiment of the present disclosure. In this example, the first sink 208 of the first restroom unit 156 is coupled to the first surface 204 of a partition wall 196 at an intermediate position between the first end wall 164 and the second end wall 168, and the second sink 214 is coupled to the machine exterior wall 176. The configuration of the sinks and toilets in the first restroom unit 156 and the second restroom unit 158 ​​shown in Figure 6 is merely illustrative. The sinks and toilets may be provided in various areas different from those shown.

[0075] Figure 7 is a top view showing a restroom system 150 in an internal cabin 152 according to one embodiment of the present disclosure. In the restroom system 150 shown in Figure 7, a partition wall 196 is configured to be movable between a closed position and an open position. In the closed position, the internal chamber 182 is separated to define a first restroom unit 156 and a second restroom unit 158. In the open position, the internal chamber 182 provides a large, expanded single restroom space that is easily and comfortably accessible to persons with limited mobility. Except for this configuration, the restroom system shown in Figure 7 is similar to the restroom system shown in Figure 5. The first sink 208, first toilet 210, second sink 214, and second toilet 216 do not necessarily have to be connected to the movable part of the partition wall 196. For example, the partition wall 196 includes a plurality of foldable segments 230 connected to each other via hinges 232, which allow the partition wall 196 to be folded and detached from one or both of the first end wall 166 and the second end wall 168. In this embodiment, the partition wall 196 is foldable or collapsible. The folded partition wall 196 may be fixed to the interior wall, removed and stored in the lavatory system 150, or stored elsewhere in the interior cabin 152. As another example, the partition wall 196 may be configured to extend and retract between an open position and a closed position. As yet another example, the partition wall 196 may be configured to slide between an open position and a closed position. As yet another example, the partition wall 196 may be a curtain or drape with sound-absorbing elements. That is, the partition wall 196 may be a movable wall having segments configured to move to move the partition wall 196 between an open position and a closed position.

[0076] Figure 8 is a top view showing a restroom system 150 in an internal cabin 152 according to one embodiment of the present disclosure. The restroom system 150 shown in Figure 8 is configured such that a partition wall 196 is movable between a closed position and an open position, as described in relation to Figure 7. In the closed position, the internal chamber 182 is separated to define a first restroom unit 156 and a second restroom unit 158. In the open position, the internal chamber 182 provides a large, expanded single restroom space that is easily and comfortably accessible to persons with limited mobility. Except for this configuration, the restroom system shown in Figure 8 is similar to the restroom system shown in Figure 6.

[0077] Figure 19 is a top view showing a restroom system 150 in an interior cabin according to one embodiment of the present disclosure. In this example, the restroom system 150 includes a partition wall 196 having one or more sliding or telescopic segments 197.

[0078] Referring to Figures 5-8 and Figure 19, the restroom system 150 allows for the placement of two restroom units in the space of three passenger seats. Conventional restrooms occupy approximately 20% to 30% more space vertically than passenger seats, so installing two restrooms requires the removal of 6 to 12 passenger seats. The area of ​​conventional restrooms ranges from 10.8 to 13.4 square feet. In contrast, the restroom system 150 described herein provides two restroom units in an area of, for example, 13 square feet, which is the same as or similar to the area of ​​a single assembly consisting of, for example, three passenger seats (60 inches x 32 inches).

[0079] In at least one example, the lavatory system 150 is located at the end of a row of seats adjacent to an exit. A second (or out-of-flight) lavatory unit 158 ​​opens to an exit route 170, such as a lateral exit passage leading to a storage space used by cabin crew during an emergency evacuation (the lavatory is not used in this emergency situation). A first (or in-flight) lavatory unit 156 opens to a passage 160, or alternatively, to the same exit route 170. As one option, since the first lavatory unit 156 is located on the in-flight side of the cabin crew assistance space 220, the first lavatory unit 156 may extend longer longitudinally than the second lavatory unit 158.

[0080] Figure 9 is a perspective view showing a lavatory system 150 adjacent to an exit door 260, such as an exit door of an aircraft, according to one embodiment of the present disclosure. The exit door 260 is located at the end of an exit path 170. Optionally, the lavatory system 150 may include a movable barrier 262 movably coupled to a second lavatory unit 158. The barrier 262 may be a panel, wall, screen, door, curtain, etc., configured to move between an deployed position, as shown in Figure 9, where the barrier 262 is positioned in front of the exit door 260, and a retracted position where the exit door 260 is visible from inside the interior cabin 152.

[0081] The barrier 262 can be movably coupled to the second restroom unit 158, other parts of the restroom system 150, or parts of the interior cabin via hinges, slides and tracks, etc. For example, the barrier 262 may be configured to pivot between an extended position and a retracted position, for example, around one or more hinges. As another example, the barrier 262 may be configured to slide between an extended position and a retracted position. As yet another example, the barrier 262 may be configured to extend and fold between an extended position and a retracted position.

[0082] When passengers enter or exit the interior cabin 152, for example, when they enter the exit path 170 through the open exit door 260, the barrier 262 is in the retracted position. During flight, the barrier 262 is moved to the deployed position, as shown in Figure 9. In the deployed position, the barrier 262 can prevent people from touching the exit door 260 by concealing the exit door 260, or at least a part of it (e.g., the handle 264), and can also ensure that no particular individual is at risk of inadvertently grasping the handle 264.

[0083] Figure 10 is a front view showing a barrier 262 in the deployed position according to one embodiment of the present disclosure. The barrier 262 may include a handle 270 that can be grasped to move the barrier 262 between the deployed position and the retracted position. The barrier 262 may also include a marker 272 indicating the location of the second restroom unit 158 ​​(shown in Figure 9). This is particularly important because the door of the second restroom unit 158 ​​may be obscured by the extension of the first restroom unit 156. The marker 272 may be painted or printed on the barrier 262. As another example, the marker 272 may be a decal. As yet another example, the marker 272 may be a plate or panel attached to the barrier 262. As yet another example, the marker 272 may be illuminated by one or more lighting assemblies, etc.

[0084] Barrier 262 can be used in any of the restroom systems 150 described herein. Optionally, the restroom system 150 may not include barrier 262.

[0085] Figure 11 is a perspective view showing a restroom 300 connected to row 302 of an overhead luggage rack assembly 304 (for example, an overhead luggage rack assembly 118 shown in Figure 3) according to one embodiment of the present disclosure. The restroom 300 may be a restroom system 150 as described herein. For example, the restroom 300 may be a second restroom unit 156 as shown in Figures 5 to 9. As another example, the restroom 300 may be a single-unit restroom, whether or not it is part of a restroom system 150 as described herein.

[0086] A portion of row 302 is directly connected to the restroom 300, for example, to the front or rear end of the restroom 300. For example, the luggage rack assembly 304 may be directly connected to the restroom 300 at the upper part 306 of the restroom 300. As another example, the luggage rack assembly 304 may be connected to the restroom 300 by end caps 308 of row 302.

[0087] The end cap 308 and / or luggage rack assembly 304 form a storage compartment 310 that extends outward from the outer wall 312 of the restroom 300, such as in the upper portion that is positioned overhead and aligned with the luggage rack assembly 304. The storage compartment 310 defines an internal storage space 314 that connects to the internal chamber 316 of the restroom 300. The internal chamber 316 is defined by one or more outer walls (including the outer wall 312). The storage compartment 310 extends outward from one or more of these outer walls. In other words, the storage compartment 310 is not located inside the internal chamber 316. In this way, the storage compartment 310 can be used instead of one or more cabinets located inside the restroom 300, and as a result, more free space can be secured inside the restroom 300.

[0088] A movable partition or storage access door may be provided between the storage compartment 310 and the internal chamber 316 of the restroom 300. The storage access door is movable between an open position in which the internal storage space 314 is open to the internal chamber 316 and a closed position in which the internal storage space is closed to the internal chamber 316. Various items such as toilet paper and facial tissues may be stored in the internal storage space 314 rather than in the internal chamber 316 of the restroom 300.

[0089] As shown in the figure, the storage compartment 310 is directly connected to the internal chamber 316 of the lavatory 300, but is not located inside the internal chamber 316. Alternatively, the storage compartment 310 may be part of the end cap 308 and / or luggage rack assembly 304 outside the internal chamber 316 of the lavatory 300. The internal storage space 314 of the storage compartment 310 is accessible from inside the internal chamber 316 of the lavatory 300. By recessing the cabinet space into the end cap 308 and / or overhead luggage rack assembly 304, more space can be created in the internal chamber 316 (which may otherwise be occupied by one or more cabinets). In general, integrating the storage compartment 310 with the lavatory 300 can reduce the need for cabinet space within the lavatory 300.

[0090] Figure 12 is a perspective view showing a storage compartment 310 extending outward from a restroom 300 according to one embodiment of the present disclosure. As described above, the storage compartment 310 may be at least part of an end cap coupled to a luggage rack assembly, or it may be at least part of a luggage rack assembly. The internal storage space 314 of the storage compartment 310 is connected to the internal chamber 316 of the restroom 300 by an access opening 320. The access opening 320 may be formed in the wall 322 of the restroom 300, such as the front wall or the rear wall.

[0091] The storage access door 324 is movably coupled to the storage compartment 310 and / or wall 322. The storage access door 324 is movable between an open position and a closed position. Between the open and closed positions, the storage access door 324 can pivot around one or more hinges or slide on one or more tracks.

[0092] In at least one example, a lighting assembly 326 may be provided within the storage compartment 310. The lighting assembly 326 is configured to illuminate the internal storage space 314. In at least one example, the lighting assembly 326 is functionally coupled to the storage access door 324, for example, via a switch 328. Thus, the lighting assembly 326 may operate to illuminate the internal storage space 314 when the storage access door 324 is open and deactivate when the storage access door 324 is closed.

[0093] The storage compartment 310 can be used in any of the examples described herein. For example, the storage compartment 310 can be connected to either a dressing room or a dressing room unit as described herein.

[0094] Figure 13 is a perspective interior view showing a storage compartment 300 for a first restroom 302 connected to a second restroom 304, according to one embodiment of the present disclosure. The restroom system 301 includes a first restroom 302, a second restroom 304, and a storage compartment 300 common to (e.g., shared) the first restroom 302 and the second restroom 304. The storage compartment 300 defines a storage chamber 303. In at least one example, the first restroom 302 is a first restroom unit 156, and the second restroom 304 is a second restroom unit 158, which are described with reference to, for example, Figures 5 to 9. Optionally, the first restroom 302 and the second restroom 304 may be other than the first restroom unit 156 and the second restroom unit 304.

[0095] The first restroom 302 is separated from the second restroom 304 by a partition wall 306. For example, the partition wall 306 may be a partition wall 196 as described with reference to Figures 5 to 9.

[0096] The first restroom 302 includes a first housing 308 (such as a first cabinet), and the second restroom 310 includes a second housing 310 (such as a second cabinet). The hangar 300 is common to both the first restroom 302 and the second restroom 310. The hangar 300 penetrates the partition wall 196.

[0097] The storage compartment 300 includes a first inner end wall 312, which connects to a front wall 314, a rear wall 316, a bottom surface 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, rear wall, bottom surface 318, and upper counter 320 connect to a second inner end wall 322 on the opposite side of the first inner end wall 312. The first inner end wall 312 is located within the first restroom 302, and the second inner end wall 322 is located within the second restroom 304. The first inner end wall 312 may be part of the first housing 308, such as a first cabinet, and the second inner end wall 322 may be part of the second housing 310, such as a second cabinet.

[0098] The first inner end wall 312, the front wall 314, the rear wall 316, the bottom surface 318, the upper counter 320 (penetrating the partition wall 306), and the second inner end wall 322 define the storage chamber 303 of the hangar 300. The hangar 300 is shared by the first restroom 302 and the second restroom 304. The hangar 300 is shared by both the first restroom 302 and the second restroom 304.

[0099] A waste container 330 is housed inside the hangar 300. An access door 332 is connected to the front wall 314 of the first restroom 302, etc. For example, the access door 332 is movably connected to the front wall 312 of the first restroom 302 (or optionally the second restroom 304). The access door 302 is movably connected to the front wall 314 via one or more hinges, slides and tracks, etc. This allows the access door 302 to pivot or slide between an open position in which the storage chamber 303 of the hangar 300 is exposed and a closed position in which the storage chamber 303 of the hangar 300 is closed. When the access door 302 is in the open position, the waste container 330 can be selectively removed or rearranged.

[0100] A first waste opening 340 with a movable lid 341 is formed in the upper counter 320 of the first restroom 302. A second waste opening 342 with a movable lid 343 is formed in the upper counter 320 of the second restroom 302. Both the first waste opening 340 and the second waste opening 342 are connected to a storage chamber 303 of a storage unit 300 that is common to both the first restroom 302 and the second restroom 304. In this way, waste to be disposed of in the first restroom 302 and the second restroom 304 can be disposed of through the first waste opening 340 and the second waste opening 320 into a waste container 330 provided in the storage chamber 303 of the storage unit 300.

[0101] In at least one example, the hangar 300 may be configured to contain a fire inside. For example, the interior wall portion defining the hangar 300 may be formed of a flame-retardant material, and the joint between the wall and the access door 332 in the closed position may engage to seal each other to restrict the flow of oxygen into the hangar 300 when the access door 332 is closed. Furthermore, the hangar 300 may house fire extinguishing equipment 350, such as fire extinguishers, shared by the first restroom 302 and the second restroom 304.

[0102] The storage unit 300 can save space for both the first restroom 302 and the second restroom 304 by holding a waste container 330 used by both of them. In this way, additional space is provided for both the adjacent first restroom 302 and the second restroom 304. The storage unit 300 allows access to a single waste container 330 from adjacent restrooms 302 and 304 separated by a partition wall 306.

[0103] The hangar 300 can be used with any of the examples described herein. For example, the hangar 300 can be used with any adjacent restroom or restroom unit as described herein.

[0104] Figure 14 is a simplified front view showing a storage compartment 300 common to the first restroom 302 and the second restroom 302 according to one embodiment of the present disclosure. The storage compartment 300 penetrates the partition wall 306, with the first part 300a of the storage compartment 300a located inside the first restroom 302, and the second part 300b of the storage compartment 300b located inside the second restroom 302.

[0105] In at least one example, the first container portion 330a of the waste container 330 is located below the first waste opening 340, and the second container portion 330b of the waste container 330 is located below the second waste opening 342. In this way, waste passing through the first waste opening 340 and the second waste opening 342 is received in the storage chamber 331 of the waste container 330.

[0106] Figure 15 is a simplified front view showing a storage compartment 300 common to the first restroom 302 and the second restroom 304 according to one embodiment of the present disclosure. The waste container 330 does not have to be located directly below the first waste opening 340 and / or the second waste opening 342. For this reason, the first waste duct 350 may be connected to the first waste opening 340, and the second waste duct 352 may be connected to the second waste opening 342. The first waste duct 350 and the second waste duct 352 are connected to the storage chamber 331 of the waste container 330.

[0107] Figure 16 is a flowchart showing a method 400 for forming a restroom system within the interior cabin of a vehicle. Method 400 includes, in 402, providing a housing that defines an interior chamber; in 404, forming a first restroom unit within the interior chamber; and in 406, forming a second restroom within the interior chamber. The first restroom unit is adjacent to the second restroom unit.

[0108] In at least one example, forming the second lavatory 406 includes forming a portion of the exterior wall of the interior cabin as the exterior wall of the second lavatory.

[0109] In at least one example, forming the first restroom unit 404 includes connecting a first entrance to the first restroom unit to a passage in the interior cabin, and forming the second restroom unit 406 includes connecting a second entrance to the second restroom unit to an exit passage in the interior cabin.

[0110] In at least one example, the method includes forming a partition wall within the internal chamber and using the partition wall to separate the first restroom unit from the second restroom unit. In a further example, the method may include moving the partition wall between a closed position and an open position, in the closed position the internal chamber is separated into the first restroom unit and the second restroom unit, and in the open position the internal chamber provides a larger, expanded single restroom space.

[0111] As another example, the method described above includes movably coupling a barrier to either the first or second restroom unit, and moving the barrier between an deployed position and a retracted position. In the deployed position, the barrier is positioned in front of the vehicle's exit door. When the barrier is in the retracted position, the exit door is visible from inside the interior cabin.

[0112] Optionally, the method includes providing in 408 a storage compartment extending outward from the outer wall of one or both of the first or second restroom unit. The storage compartment defines an internal storage space connected to the internal chamber. Alternatively, the method includes step 408 in relation to a restroom system, restroom, or restroom unit, but does not include steps 402-406.

[0113] Optionally, the above method includes providing a storage compartment common to the first restroom unit and the second restroom unit in 410. Alternatively, the above method includes step 410 in relation to a restroom system, restroom, or restroom unit, but does not include steps 402-408. Alternatively, the above method includes steps 408 and 410, but does not include steps 402-406.

[0114] Figure 17 is a flowchart illustrating a method 500 for forming a restroom within the interior cabin of a vehicle. The method 500 includes, in 502, defining an interior chamber of the restroom by one or more outer walls; in 504, extending a storage compartment outward from at least one of the outer walls; and in 506, connecting the interior storage space of the storage compartment to the interior chamber.

[0115] In at least one example, the method includes forming at least a portion of the luggage rack assembly as the storage compartment. In another example, the method includes forming at least a portion of the end caps connected to the luggage rack assembly as the storage compartment.

[0116] In at least one example, the method includes providing a storage access door between the storage compartment and the internal chamber, and moving the storage access door between an open position and a closed position. When the storage access door is in the open position, the internal storage space is open to the internal chamber. When the storage access door is in the closed position, the internal storage space is closed to the internal chamber.

[0117] In at least one example, the extension includes directly connecting the storage compartment to the internal chamber. The storage compartment is not located within the internal chamber.

[0118] As an example, the above method includes forming access openings in one or more outer walls and connecting the internal storage space to the internal chamber through the access openings.

[0119] In at least one example, the method includes providing a lighting assembly within the internal storage space of the storage compartment. In a further example, the method includes functionally connecting the lighting assembly to a storage access door of the storage compartment, activating the lighting assembly to illuminate the internal storage space when the storage access door is open, and deactivating the lighting assembly when the storage access door is closed.

[0120] Figure 18 is a block diagram showing a method 600 for forming a restroom system within the interior cabin of a vehicle. Method 600 includes, in 602, providing a storage compartment common to a first restroom unit and a second restroom unit adjacent to the first restroom unit.

[0121] In at least one example, the method includes extending the storage unit such that it passes through a partition wall separating the first restroom unit from the second restroom unit.

[0122] In at least one example, the storage compartment includes a first inner end wall, a front wall, a rear wall, a bottom surface, an upper counter, and a second inner end wall opposite to the first inner end wall within the first restroom unit. The second inner end wall is located within the second restroom unit. The first inner end wall, the front wall, the rear wall, the bottom surface, the upper counter, and the second inner end wall define the storage chamber of the storage compartment.

[0123] In at least one example, the method includes housing a waste container within the storage facility.

[0124] As another example, the method described above includes forming an access door in one of the first restroom unit or the second restroom unit, and moving the access door between an open position and a closed position. When the access door is in the open position, the storage compartment is exposed. When the access door is in the closed position, the storage compartment is closed.

[0125] In at least one example, the method includes forming a first waste opening in the first restroom unit, the first waste opening being connected to a storage chamber in the storage unit. The method also includes forming a second waste opening in the second restroom unit, the second waste opening being connected to the storage chamber in the storage unit.
