Description

[0001] The invention relates to an onboard toilet in or for a passenger cabin of a passenger aircraft, which is intended to be usable by persons with reduced mobility (PRM).

[0002] WO 2021 / 040615 A1 discloses an accessible toilet unit for an aircraft cabin. The toilet unit is configurable between a configuration for able-bodied persons and a configuration for PRM (Persons with Reduced Mobility) access. In the configuration for able-bodied persons, the toilet unit has a first internal floor area, and outside the toilet unit is a cabin floor area. The toilet unit can be expanded into the PRM-accessible configuration, in which it is expanded to have a second internal floor area, the second internal floor area encompassing a portion of the cabin floor area. A washbasin for an aircraft toilet unit is also disclosed.

[0003] The object of the present invention is to propose improvements with regard to an on-board toilet in a passenger cabin of a passenger aircraft, which is intended to be usable by persons with reduced mobility.

[0004] The problem is solved by a spatial section according to claim 1. Preferred or advantageous embodiments of the invention and of other invention categories will become apparent from the further claims, the following description and the accompanying figures.

[0005] The space section is a section of a passenger cabin designed for use in a passenger aircraft designed for use in that aircraft. "Designed for use in that aircraft" means that the space section is structurally adapted to and equipped for specific types of passenger cabins or passenger aircraft; for example, it is designed to meet the resulting geometric and system requirements, etc.

[0006] In other words, the passenger cabins or passenger aircraft in question are assumed to be known with regard to their geometry and system requirements, etc.

[0007] The passenger aircraft has a longitudinal direction or axis, or extends along it. A transverse direction of the aircraft runs perpendicular to this. The direction of flight of the passenger aircraft runs along the longitudinal axis and is directed from the tail to the nose of the aircraft. The passenger aircraft contains a passenger cabin. The passenger aircraft contains a cockpit wall. The cockpit wall delimits the passenger cabin longitudinally. In the direction of flight, the cockpit wall delimits the passenger cabin at the front. The passenger aircraft has two side walls that delimit the passenger cabin laterally; in the above nomenclature, these are referred to as "left" and "right" (when viewed in the direction of flight).

[0008] The passenger cabin includes an emergency exit area. This is set back from the cockpit wall lengthwise, opposite the direction of flight. "Set back" means that there is a space between the cockpit wall and the emergency exit area, which houses the lavatory and galley described below. The emergency exit area connects two aircraft doors located opposite each other in the cabin walls.

[0009] The passenger cabin also contains a seating area. This area follows the emergency exit area – viewed lengthwise, against the direction of flight – and is therefore located behind it. Within the seating area are rows of passenger seats, the details of which are not typically specified. The passenger cabin also includes a cockpit aisle. This runs lengthwise from the cockpit wall to the emergency exit area.

[0010] This section of space extends lengthwise from the cockpit wall to the seating area. Laterally, it extends to both sides of the aircraft, thus encompassing the entire width of the passenger cabin or aircraft. This section includes the emergency exit area.

[0011] This section of the cabin contains a lavatory. The lavatory is bounded lengthwise at the front by the cockpit bulkhead and at the rear by the emergency exit area, thus extending from the cockpit bulkhead to the emergency exit area. Laterally, it is bounded on one side by one of the bulkheads (e.g., the left one) and on the other by the cockpit aisle, thus extending from the (e.g., left) bulkhead to the cockpit aisle. Specifically, the lavatory is located to the left of the cockpit aisle when viewed in the direction of flight.

[0012] This section of the cabin also contains a galley. The galley is located on the other side of the cockpit aisle, opposite the lavatory. In other words, the lavatory is on one side (e.g., the left), and the galley is on the other side of the cockpit aisle (to the right). Longitudinally, the galley is bordered at the front by the cockpit bulkhead and at the rear by the emergency exit area. Laterally, it is bordered on one side by the other bulkhead (e.g., the right one) and on the other by the cockpit aisle. Specifically, viewed in the direction of flight, the galley is located to the right of the cockpit aisle.

[0013] The onboard toilet and galley with cockpit access mean that the space in the passenger aircraft or passenger cabin is used particularly well.

[0014] The onboard toilet contains an internal functional element. This is a toilet seat, i.e., the actual toilet / toilet bowl.

[0015] The ship's toilet is also associated with at least one external functional element. At least one, and in particular all, of these external functional elements are located in the galley and not in the ship's toilet. Functional elements are those that may be necessary, or are particularly necessary, for the intended use of a ship's toilet (e.g., using the toilet, cleaning / washing body parts, temporarily removing stains (drinks, food, etc.) from clothing). These include, for example, hand basins, waste bins, and drying equipment (towels, hand dryers, etc.). In this case, these are therefore divided into those located within the ship's toilet (internal) and those located outside of it, namely in the galley.

[0016] In other words, according to the invention, at least one functional element of the aircraft lavatory, which is usually located within the lavatory, is removed from it and placed in the galley. This creates more space in the lavatory so that a person with reduced mobility (e.g., a wheelchair user) has more room to move around within the lavatory, particularly while seated in the wheelchair. The wheelchair is specifically an aircraft wheelchair designed for use on board the passenger aircraft. Therefore, its characteristics, such as its size, maneuverability, etc., are also known in the above sense.

[0017] In a preferred embodiment, at least one of the external functional elements is a washbasin.

[0018] Removing a sink from a standard design or layout of an onboard toilet creates significantly more space that can be used by a PRM (Personal Recovery Management) unit.

[0019] In a preferred embodiment of this design, the washbasin is accessible from underneath a standard service wheelchair. This allows people with limited mobility to comfortably reach the washbasin using the service wheelchair.

[0020] In a preferred embodiment, the washbasin is located on a side or side wall of the galley facing the cockpit aisle. This allows for particularly convenient access from the cockpit aisle, especially if the lavatory door is also positioned to open into the cockpit aisle, i.e., in particular if it is located in a longitudinally extending side wall of the lavatory. "Side walls" in this context refer to the longitudinal direction within the aircraft.

[0021] In a preferred embodiment, at least one of the external functional elements is a waste bin, e.g., a container for used towels. Alternatively or additionally, at least one of the external functional elements is a towel dispenser. Waste bins and towel dispensers occupy a comparatively large amount of space in a conventional onboard lavatory design, so removing them from the lavatory design creates noticeably more space for use by a PRM (Personal Recovery Module).

[0022] In a preferred embodiment, the space includes a door element. This door element spans the cockpit aisle from the galley to the lavatory. The door element is located at the longitudinal end of the cockpit aisle facing the emergency exit area, i.e., opposite the direction of flight. In other words, the door element serves to open the cockpit aisle or to separate it from the emergency exit area. Specifically, the cockpit aisle can be closed off from the emergency exit area to create privacy in the cockpit aisle between the lavatory and the galley. This area is used, for example, by people who wish to use the external functional elements of the lavatory, which are located outside the lavatory and accessible from the cockpit aisle, i.e., located near the galley.

[0023] In a preferred embodiment of this design, the door element includes a folding door and / or a curtain, or is itself a folding door and / or a curtain. Such door elements are particularly space-saving and easy to manufacture.

[0024] However, an alternative design also allows for a classic door with hinges.

[0025] In a preferred embodiment, the lavatory has a toilet door. The toilet door is located in a side wall of the lavatory. This side wall separates the lavatory from the cockpit aisle and thus runs lengthwise along the passenger aircraft. This arrangement of the toilet door is particularly space-saving within the passenger cabin.

[0026] In particular, the onboard toilet also features a toilet door. This door is designed to be wide enough to accommodate a standard onboard wheelchair. This allows passengers with limited mobility to enter the toilet while seated in their wheelchair. The dimensions of such onboard wheelchairs are well-known in the industry, so the toilet door can be adjusted accordingly.

[0027] In particular, the toilet door is designed as a revolving door. A handle (see below) can be fitted to a revolving door (especially on the inside facing the toilet), which is available to a passenger boarding wheelchair (PRM) when the door is open, allowing them to maneuver in the doorway while seated in an onboard wheelchair. A door hinge is located at the front of the door, in the direction of flight.

[0028] In a preferred embodiment, the toilet seat in the onboard toilet is positioned opposite the toilet door. This results in a particularly large gap between the toilet seat and the toilet door, so that there is sufficient space in the onboard toilet for an onboard wheelchair, allowing it to maneuver, e.g., to rotate.

[0029] In a preferred embodiment, the space, in particular the lavatory and / or the cockpit aisle and / or the side of the galley facing the cockpit aisle, includes handles, in particular grab rails / bars / handrails, which are designed or arranged in such a way that a passenger (also representing any other person as driver / user) operating a properly designed onboard wheelchair can maneuver themselves and / or the wheelchair when using the space (i.e., the lavatory and associated external functional elements). Thus, the driver—especially while seated in the wheelchair—does not require any assistance from third parties when using the lavatory to move around in the relevant part of the space (lavatory / cockpit aisle), which increases their privacy.

[0030] In a preferred embodiment, the handles are therefore arranged so that a PRM, as the driver of a properly designed on-board wheelchair, can maneuver herself and / or the on-board wheelchair with respect to at least one of the other functional elements contained in the on-board kitchen.

[0031] In a preferred embodiment, the area of ​​space relating to the use of the onboard toilet (i.e. the onboard toilet and the section of the area of ​​space required for the use of the external functional elements, in particular the cockpit aisle) has a floor area that is designed such that a standard onboard wheelchair can be rotated within the onboard toilet by at least 90°.

[0032] In a preferred embodiment, the galley is designed as follows, at least up to a certain height: This certain height is the height of a standard aircraft wheelchair with a PRM (Personal Flight Operator) of average height (e.g., 1.80 m) seated on it. Such a height is, for example, 1.4 m or 1.6 m. The galley is recessed at least up to this height. However, the height is chosen independently of the aforementioned dimensions and is, in particular, 1.8 m or 2 m, or the total clear height between the floor of the cockpit aisle and its ceiling, i.e., the height of the galley there. The recessing extends at least to a longitudinal section of the cockpit aisle that borders the emergency exit area facing away from the direction of flight, i.e., the "rear end" of the cockpit aisle. In other words, the cockpit aisle widens along this longitudinal section facing away from the direction of flight, up to the emergency exit area.In particular, the galley is designed with a slanted longitudinal axis, especially when the side wall of the lavatory opposite the cockpit aisle runs parallel to the longitudinal axis. This creates a kind of conical space, allowing a PRM (Personal Rescue Crew Member) seated in a lavatory wheelchair to more easily maneuver into the cockpit aisle and from there into and out of the lavatory. This is especially true in the aforementioned embodiment where the lavatory door is located in the side wall of the lavatory.

[0033] In particular, the galley, along with the aforementioned sink, is designed with a corresponding angle; that is, the sink is also designed to taper in the opposite direction of flight, or to recede from the lavatory. This allows for the installation of a suitable sink in the angled area of ​​the galley.

[0034] In a preferred embodiment, at least one flight attendant seat is arranged on the side of the rear wall facing the emergency exit area, i.e., on the rear side of the rear wall, i.e., the outside of the lavatory. This provides additional functionality in the emergency exit area.

[0035] The object of the invention is also achieved by a passenger aircraft according to claim 14. The passenger aircraft contains the space section according to the invention. The passenger aircraft also contains the passenger cabin mentioned above, and the passenger cabin contains the space section.

[0036] The passenger aircraft and at least some of its possible embodiments, as well as their respective advantages, have already been explained in substance in connection with the spatial section according to the invention. In particular, the preferred embodiments mentioned above in connection with the spatial section also constitute preferred embodiments of the passenger aircraft.

[0037] In a preferred embodiment, the passenger aircraft is a single-aisle aircraft. The compartment according to the invention is particularly advantageous in a single-aisle aircraft because space is limited in this compartment, yet thanks to the invention, an onboard toilet for persons with reduced mobility can be integrated into the passenger aircraft in a particularly space-saving manner.

[0038] The invention is based on the following findings, observations, and considerations and further comprises the following preferred embodiments. These embodiments are sometimes referred to simply as "the invention." The embodiments may also include parts or combinations of the embodiments mentioned above, correspond to them, and / or may include previously unmentioned embodiments.

[0039] According to the invention, in particular a “FWD PRM (person with reduced mobility) Area - Lavatory (on-board toilet) A (position: front left as seen in the direction of flight) and Galley (on-board kitchen) G1 (position: front right as seen in the direction of flight) for single aisle aircraft” is provided.

[0040] The basic concept of the invention involves removing all components / functions not required for toilet use from the lavatory (especially those in front of "Door 1," i.e., on the left front) to maximize space for an onboard wheelchair. All removed functions (external functional elements) are instead installed opposite in the galley (G1). This includes, in particular, a modified, wheelchair-accessible washbasin with an integrated waste bin. A curtain or door (a door element spanning the cockpit walkway) between the two structures (galley and toilet) separates the toilet area.

[0041] The basic idea of ​​the invention is the development of a lavatory concept for existing single-aisle aircraft at the parking position in front of door 1 (front left in the direction of flight), designed to be accessible for the elderly and disabled. The limited space in front of door 1 should be used as efficiently as possible so that wheelchair users can use the toilet independently. Functions not required for a PRM lavatory should be relocated.

[0042] The invention is based on the following practical observation: Due to the very limited space available, elderly and mobility-impaired passengers currently require assistance when using the toilet; for example, the person must be helped out of their wheelchair and placed on the toilet. There is currently no privacy.

[0043] One aspect of the invention is as follows: By modifying the galley (G1), functions not required for using the toilet are removed from the lavatory (A) and positioned (as now external functional elements) in the galley (G1). This allows for more space in the lavatory (onboard toilet) without increasing its footprint. A curtain or door (a door element spanning the cockpit aisle) between the lavatory (A) and the galley (G1), as well as a second door on the lavatory (toilet door), provides privacy. Optimized handles allow the wheelchair user (PRM on an onboard wheelchair) to independently enter the lavatory and operate all its functions.

[0044] According to the invention: The PRM (Personalized Rescue Mechanism) can independently and fully use the onboard toilet, similar to accessible toilets on trains or in public spaces. Currently, this is not possible on aircraft. Due to space limitations, a second person is always required to assist. By relocating the washbasin (as an external functional element) from the lavatory to the galley, the washbasin can be used more easily by the crew, for example, while the toilet is occupied. Liquids can thus be disposed of more easily.

[0045] According to the invention, the following results: - Removing the washbasin from the lavatory to create sufficient space in the lavatory for the PRM. - Independent maneuvering of the PRM in the toilet, improved transfer angle for toilets, optimized positioned handles. - The dimensions of the lavatory will not be changed. - Existing structural connections to the lavorory and galley can continue to be used. - The washbasin will instead be integrated into the galley and is accessible from the cockpit passageway; also when using the toilet (for passengers, crew). - Galley system connections can also be used for lavatory functions (e.g. washbasin). - A curtain between the lavatory and galley can separate the FWD PRM area. - Additional curtain between lavatory and galley for improved privacy. - Enlarged door with handles for PRM.

[0046] One aspect of the invention is as follows: Remove all components / functions not necessary for toilet use from the lavatory (in front of door 1) to maximize space for the OBW (Operating Body Unit). All removed functions are instead installed (as external functional elements) opposite in the galley (G1). These include, among other things, a modified, wheelchair-accessible washbasin with an integrated waste bin. A curtain or door between the two structures separates the toilet area. Escape route requirements are met and are not restricted by the concept; therefore, the building permit remains valid.

[0047] Further features, effects, and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and the accompanying figures. These figures are shown in a schematic diagram: Fig. 1. A section of a passenger aircraft in top view showing an on-board toilet in symbolic representation, Fig. 2 the room section from Fig. 1. In detail, in a perspective oblique view from above, the onboard toilet made of Fig. 1 with the door closed, Fig. 3. The side wall of the galley with sink and waste bin in detail. Fig. 4 the room section from Fig. 2 from the top showing three different positions of a wheelchair on board, Fig. 5 the room section from Fig. 4 Detail in perspective oblique view from above with a person in three different positions.

[0048] Fig. Figure 1 shows a section of a passenger aircraft 2, specifically its nose section. The passenger aircraft 2 has a (non-directional) longitudinal axis or longitudinal direction 8, as well as a (directional) flight direction 10, in which the passenger aircraft 2 moves when flying straight ahead. The passenger aircraft 2 also has a lateral direction 14 perpendicular to the longitudinal direction 8.

[0049] The passenger aircraft 2 contains a cockpit wall 4 as well as a left side wall 6a and a right side wall 6b. Terms such as "left", "right", etc. refer here to the direction of flight 10 and the longitudinal axis 8, respectively.

[0050] The passenger aircraft 2 contains a passenger cabin 12. The cockpit wall 4 limits the passenger cabin 12 at the front, i.e. in the direction of flight 10. In the lateral direction 14, i.e. left and right, the hull walls 6a,b limit the passenger cabin 12.

[0051] The aircraft contains two front aircraft doors 18a,b.

[0052] The passenger cabin 12 contains an emergency exit area 16, which extends between the two aircraft doors 18a,b in a transverse direction 14. The emergency exit area 16 is spaced from the cockpit wall 4 in a longitudinal direction 8.

[0053] The passenger aircraft 2 contains a seating area 20. This contains passenger seats 22, which are only symbolically indicated here, for passengers of the passenger aircraft 2 that are not shown. To the left and right of a central aisle 60 of the passenger cabin 12, the passenger seats 22 are grouped into seating groups 62 of two passenger seats 22 each.

[0054] The passenger aircraft 2 is a single-aisle passenger aircraft, which therefore only has the single aisle 60 between each row or group of seats 62 of the passenger seats 22.

[0055] Seating area 20 is located opposite the direction of flight 10, beyond or behind emergency exit area 16.

[0056] The passenger aircraft 2 also contains a cockpit aisle 24, which extends from the cockpit wall 4 (or the cockpit in front of it) to the emergency exit area 16.

[0057] Passenger aircraft 2, or passenger cabin 12, contains a space section 30.

[0058] Section 30 extends longitudinally 8 from cockpit wall 4 to seating area 20 and transversely 14 to the two hull sides 6a,b. Section 30 contains emergency exit area 16.

[0059] Section 30 also contains a toilet 32 ​​and a galley 33, which are separated from each other by the cockpit passage 24.

[0060] The onboard toilet 32 ​​is bounded longitudinally 8 at the front by the cockpit bulkhead 4 and at the rear by the emergency exit area 16. In the transverse direction 14, or laterally, the onboard toilet 32 ​​is bounded on one side (here on the left) by one of the hull bulkheads, here the left hull bulkhead 6a, and on the other side (right) by the cockpit aisle 24.

[0061] The galley 33 is bounded longitudinally 8 at the front by the cockpit bulkhead 4 and at the rear by the emergency exit area 16. Laterally 14, the toilet 32 ​​is bounded on one side (here on the right) by the other bulkhead, in this case the right bulkhead 6b, and on the other side (left) by the cockpit walkway 24.

[0062] Fig. Figure 1 shows the onboard toilet 32 ​​and onboard kitchen 33 only symbolically as rectangles, whereby the onboard kitchen 33 actually has a different shape on the side wall facing the cockpit passage (see below).

[0063] Fig. 2 shows room section 30 from Fig. 1 in detail, with the ship's toilet 32 ​​and ship's galley 33 opposite the cockpit passage 24. The ship's toilet 32 ​​contains as an internal functional element 70 the actual toilet, i.e. a toilet bowl or a toilet seat 46.

[0064] The onboard toilet 32 ​​is, however, assigned two further external functional elements 72a,b. These are not located in the onboard toilet 32, but rather in or on the onboard galley 33. Functional element 72a is a washbasin 48, and functional element 72b is a waste bin 74. Because the two external functional elements 72a,b are not located in the onboard toilet 32, additional space is created in it (compared to a situation in which the two functional elements 72a,b would be located inside it) so that a PRM 64 (Person with reduced mobility, see Fig. 5) therein with her on-board wheelchair 44 (OBW, on-board wheelchair, see Fig. 5) can move at all or better, or more space is available for them.

[0065] The washbasin 48 is accessible from underneath by the ship's wheelchair 44. The washbasin 48 is also located on a side 76 facing the cockpit aisle 24, in the form of a side wall of the galley 33. This side wall generally runs along the longitudinal direction 8, but is partially beveled, see below.

[0066] A rear wall 34 of the lavatory 32 extends in a transverse direction 14 and separates it from the emergency exit area 16. Two flight attendant seats 36 are arranged on the (rear) side 38 of the rear wall 34 facing the emergency exit area 16.

[0067] The ship's toilet 32 ​​has a side wall 42. This wall separates the ship's toilet 32 ​​from the cockpit aisle 24. The ship's toilet 32 ​​has a toilet door 40. The toilet door 40 is located in the side wall 42. The toilet door 40 is designed as a revolving door. Fig. Figure 2 shows toilet door 40 in the open position.

[0068] The toilet door 40 is designed with regard to its width B so that it can be used by a standard on-board wheelchair 44 (see Fig. 4, Fig. 5) is passable.

[0069] The toilet seat 46 is located in the onboard toilet 32 ​​opposite the toilet door 40, i.e. on or adjacent to the hull wall 6a.

[0070] Fig. 3 shows a detail from Fig. 2, namely the external functional elements 72a,b in or on side 76 of the galley 33. A height H is defined here as the height of the intended onboard wheelchair 44 including a PRM 64 sitting on it of average size of here 1.80m, determined here by a test.

[0071] Fig. Figure 3 shows that up to this height H, the galley 33 is angled, so that the cockpit aisle 24 widens in the opposite direction of flight 10. In other words, viewed in the opposite direction of flight 10, the galley 33 increasingly recedes from the longitudinally oriented side wall 42 of the lavatory 32, or rather, the distance between them increases. This occurs along a longitudinal section 80 of the cockpit aisle 24, which begins at its rear longitudinal end 82. Specifically, the washbasin 48 is also designed to taper in the opposite direction of flight 10 for this purpose.

[0072] Fig. Figure 4 shows the situation again from a top view. It can be seen that this creates additional conical or wedge-shaped space / clearance so that a PRM 64 can sit on a deck chair 44 (see Fig. 5) From cockpit aisle 24, it is more convenient to pass through toilet door 40 to enter or exit the onboard toilet 32. For clarity, the onboard wheelchair 44 is shown here in three positions P1-3, into which it can be maneuvered in compartment 30.

[0073] Fig. Figure 4 also shows a door element 78, which spans the cockpit aisle 24 and extends from the lavatory 32 to the galley 33. The door element 78 is located at the end of the cockpit aisle 24 that faces the emergency exit area 16, i.e., the longitudinal end 82. It thus separates the cockpit aisle 24 from the emergency exit area 16. The door element 78 is a curtain that can be drawn to separate the cockpit aisle 24 from the emergency exit area 16 and thus create privacy in the combined area of ​​the cockpit aisle 24, the lavatory 32, and the galley 33, as well as the external functional elements 72a and 72b located therein.

[0074] The onboard toilet 32 ​​contains handles 52, here in the form of grab rails or grab bars. The handles 52 are designed and distributed in the compartment 30 in such a way that a driver, here a person with reduced mobility: PRM 64 (see Fig. 5) The operator of the onboard wheelchair 44 can safely maneuver both themselves and the onboard wheelchair 44 within the onboard toilet 32, in the cockpit aisle 24, and in relation to the external functional elements 72a,b. Thus, the PRM 64 does not require assistance when using the toilet, the sink 48, or the waste bin 74, and their privacy is preserved. In other words, the PRM 64 can maneuver within the space section 30 without getting up from the onboard wheelchair 44.

[0075] Fig. Figure 4 shows the above-described on-board wheelchair 44 in use by the, for the sake of clarity only in Fig. 5 shown PRM 64 and thus the PRM 64 when using the on-board toilet 32. The on-board wheelchair 44 is in Fig. Figure 4 shows the PRM 64 at three different times and in three different positions P1-3 inside and on board the toilet 32. Position P1 shows the PRM 64 entering the toilet 32. The toilet door 40 is open at this point. After entering the toilet 32, the PRM 64 can close the toilet door 40 again (not shown here for clarity). This ensures complete privacy.

[0076] The transition from P2 to P3 shows that the PRM (with the toilet door 40 now closed) can turn or rotate within the toilet 32 ​​using the onboard wheelchair 44. P3 shows that this allows a transfer from the onboard wheelchair 44 to the toilet seat 46 without assistance.

[0077] Fig. Figure 4 also illustrates that the onboard toilet 32 ​​has a floor area 56 as follows: This is designed such that the onboard wheelchair 44 can be rotated at least 90° within the onboard toilet 34. In this case, this is achieved by mounting the toilet seat 46 diagonally in the front left corner of the space, so that maneuvering the onboard wheelchair 44 in position P2 – viewed in the direction of flight 10 – is possible behind it.

[0078] Fig.Figure 5 shows more clearly, using the PRM 64, the use of the ship's toilet 32 ​​by the PRM 64, which sequentially assumes positions P1 to P3. In position P1, the PRM 64, seated on the ship's wheelchair 44, is entering the ship's toilet 32. The toilet seat 46 is positioned far enough from the rear wall 34 of the ship's toilet 32 ​​that the PRM 64 fits between the toilet seat 46 and the rear wall 34. From this position P2, the PRM 64 can move backward and simultaneously rotate 90° counterclockwise to position P3 in front of the toilet seat 46, in order to transfer onto the toilet seat 46. Thus, she can use the ship's toilet 32 ​​for urination without assistance.
