Patent Description:
The invention relates to a cabin for a vehicle comprising a modular cabin segment.

Vehicles for transporting passengers, which vehicles have a cabin with passenger seats arranged therein, usually need to meet economic expectations so that, in the design of passenger cabins with limited space provided, the largest-possible number of passengers can be transported. In particular if the vehicle is used to travel longer distances, apart from the passenger seats, further equipment features are required in order to ensure passenger wellbeing. Apart from toilets this also relates to equipment for heating, cooling, the preparation and storage of food and drinks.

Parallel to this, in particular in the case of commercial aircraft or other technically complex vehicles, there is also the desire of many operators to design a cabin according to their own wishes. Usually, in the case of aircraft this requirement is met by a number of galley monuments or toilet monuments standardized by the manufacturer of the aircraft. These monuments often separate individual cabin sections from each other in longitudinal direction of the cabin and are often provided so as to be separate from each other.

Furthermore, in particular in commercial aircraft it is a regulatory requirement to provide a cabin attendant seat for each cabin attendant so that each cabin attendant can take up a safe position during takeoff and landing of the aircraft, which cabin attendant seat additionally occupies already confined space in the cabin.

<CIT> and <CIT> disclose an aircraft with a number of supply devices and toilets that are designed as independent conventional toilet compartments.

<CIT> (which is a late published document in relation to the underlaying parent application of the present divisional application), according to its abstract, relates to a toilet assembly for a means of transportation comprising a first toilet space, a thereto adjoining second toilet space and a partition located between the first toilet space and the second toilet space, wherein the partition is movably mounted and designed to be moved into an open position in which a separation between the first toilet space and the second toilet space is eliminated. In this way, two relatively small toilet spaces can be converted into a larger toilet space, which is suitable for use by persons having limited mobility.

<CIT> (which is also a late published document in relation to the underlying parent application of the present divisional application), according to its abstract, relates to a monument complex for a rear area of a passenger cabin. The rear contour of the monument complex is adapted to the contour of the bulkhead so that an additional wash basin can be installed without there being any loss of space in the passenger cabin.

<CIT>, according to its abstract, relates to a dual pivot expandable lavatory for use in limited spaces such as on an airplane. The lavatory may be positioned proximate the doorway area of the airplane, and is provided with a primary and a secondary pivotable module. Each module is pivotably attached to a stationary assembly conventionally affixed to the ceiling and floor of the airplane. During take-off and landing both modules are locked, by means of a locking system, in a stowed position within the stationary assembly. During routine flight, the locking system is unlocked and both modules are pivoted into a deployed position within the doorway area. A flight attendant's seat may be affixed to the exterior of the primary module. If the seat is used, an additional support foot is affixed to the primary module to accommodate the additional loading on the lavatory.

<CIT>, according to its abstract, relates to a door system for an aircraft having a flight deck door hingely coupled to a flight deck bulkhead. A lavatory is adjacent to the flight deck bulkhead and formed of a lavatory bulkhead. A lavatory door is coupled to the lavatory bulkhead. A latching mechanism is attached to the flight deck door. The latching mechanism in a first position engages the flight deck bulkhead and in a second position engages the lavatory bulkhead.

It is thus the object of the invention to propose an advantageous design of a cabin or of a cabin segment, which design allows the best possible use of the available installation space in the cabin while meeting all the regulations and the requirements for comfort.

The object is met by a passenger cabin for a vehicle having a modular cabin segment with the features of the independent claim <NUM>. Advantageous improvements are stated in the subordinate claims.

The core of the invention consists of proposing a modular cabin segment installed at a rear section of the cabin, which cabin segment comprises a modular design. In this context the term "modular" means that various modules tailored to different requirements can be selected and composed in order to be able to provide a cabin segment that is particularly advantageous to the respective operator. The term "module" refers to a part, a component or a section of a finished cabin segment. Due to the modularity each operator of the vehicle can compose a cabin segment without the need to resort to a cost-intensive individual solution. At the same time this is economically sensible for the manufacturer of the vehicle, because many different variants of a cabin segment can be proposed without the need to conceive protracted and cost-intensive individual solutions.

The modular cabin segment in the passenger cabin according to the invention is proposed for a region in the cabin, in which region a passage is not required. This could, for example, relate to a rear section of an aircraft. In other vehicles, for example in ferries, trains or the like, such a modular cabin segment could also be arranged in a rear part of the vehicle in question. The use of a rear section makes sense in particular in commercial aircraft, because in them a pressure bulkhead is arranged to delimit the cabin, which pressure bulkhead comprises an outward-curvature that could be used by toilet arrangements.

Below, some references relate to a longitudinal axis, a transverse axis and/or a vertical axis. The term "longitudinal axis" refers to the spatial direction that correlates with a longitudinal axis of the vehicle or with a parallel to the aforesaid, wherein this longitudinal axis can also be the longitudinal axis of a cabin in which the cabin segment according to the invention is arranged. Consequently, the term "transverse axis" relates to an axis that is arranged so as to be perpendicular to the longitudinal axis and that is situated in the horizontal. Accordingly, the term "vertical axis" refers to the axis that extends in vertical direction and that is situated so as to be perpendicular both on the longitudinal axis and on the transverse axis.

A modular cabin segment of the passenger cabin according to the invention comprises a first lateral segment module that accommodates a first toilet arrangement with at least one toilet compartment. The cabin segment further comprises a second lateral segment module, wherein in each case a lateral face of the first and of the second lateral segment module is designed to snugly fit in each case to an inner wall of the cabin of the vehicle so as to correspond to the aforesaid. Further, the second lateral segment module is a galley module.

The cabin segment according to the invention thus extends in a transverse axis from a sidewall of a cabin that is to be equipped with the cabin segment up to the opposite sidewall, wherein this space comprises at least one first lateral segment module and a second lateral segment module. Such a cabin segment can be designed in a particularly advantageous manner by the integration of various functions so that the space taken up by the cabin segment according to the invention is utilized as optimally as possible.

Although this is not part of the claimed invention, a special feature on the one hand consists of the possibility of positioning, apart from a first toilet arrangement, also completely different arrangements in the cabin segment.

According to the claimed invention, a cabin attendant seat is pivotally arranged on one of the modules, wherein the special feature consists of pivoting on an axis, and preferably on a vertical axis, wherein the bearing arrangement that can be pivoted is implemented laterally. In known cabin attendant seats that can be pivoted it is often necessary to pivot or rotate a kind of platform or base plate which, due to the geometric extension needed for this, severely restricts the possibilities of the surrounding installation space.

The bearing arrangement that can be laterally pivoted makes it possible to pivot a cabin attendant seat, for example from an in-use position to a stowed position so that the design space usually taken up by the cabin attendant seat is useable for other purposes almost without restriction.

In an advantageous embodiment of the invention, the cabin attendant seat is held on the at least one module in such a manner that it can be pivoted either in front of a toilet arrangement or in front of at least one storage compartment. Pivoting it in front of at least one storage compartment simplifies, in particular, pivoting the cabin attendant seat to a stowed position and to an in-use position, as well as locking it in those positions. In the case of pivoting in front of access openings of toilet arrangements the locking mechanism would have to be implemented either directly on the bearing arrangement that can be pivoted or in the floor region, or wall thicknesses of a housing of the toilet arrangement would have to be reinforced in order to accommodate locking means. If the cabin attendant seat is, for example, held on a galley module with storage compartments, because of the use for accommodating cabin trolleys and for storing food, compartments are provided in that location, which compartments can withstand greater mechanical loads than is the case with pure space dividing walls, which compartments can relatively easily accommodate the hinge of the cabin attendant seat and its load. In order to allow for future modification of a cabin segment according to the invention to allow an attendant seat to be retrofitted a relevant walling of the housing of the toilet arrangement or another walling of one of the lateral segment modules would have to be reinforced.

In an advantageous embodiment of the invention the cabin segment furthermore comprises at least one central module that is arranged between the first lateral segment module and the second lateral segment module.

According to the claimed invention, the second lateral segment module is a galley module. In the simplest case a galley module can comprise storage compartments for accommodating food, cutlery, napkins, auxiliary utensils and the like. In particular when used in an aircraft such storage compartments comprise flaps with a locking mechanism so that the objects are secured against falling out. Likewise, a galley module can comprise one or several parking spaces for cabin trolleys used to store food, transport them to the passengers in the cabin, and subsequently take up waste and the like. If required, the parking space can also comprise a cooling device, or can be connected to a central cooling device, located further away within the vehicle, in order to cool food and drinks in the corresponding cabin trolley.

In the modular cabin segment a parking space can be arranged whose dimensions make it possible to accommodate a wheelchair in its folded state. Particularly preferably, for this purpose a parking space for a cabin trolley is modified in such a manner that it provides the necessary width and height to accommodate the wheelchair and thus can be reconfigured from a parking space for a cabin trolley to a parking space for a folded wheelchair, when desired. Normally, these dimensions exceed the space required for the cabin trolley. If required, or if there is a corresponding operating regulation to carry the wheelchair of a person with limited mobility in the passenger cabin during the flight or during the journey, the cabin segment thus allows non-blocking and practical accommodation of the wheelchair.

In an advantageous embodiment any desired module of the cabin segment could comprise a parking space for a cabin trolley which in a delimitation surface comprises a rail or some other guide means that make it possible to readily insert the cabin trolley and lock it into place, and at the same time however also makes it possible to accommodate a wheelchair in its folded state in the parking space. Furthermore, the parking space for the cabin trolley in this case could comprise a cover flap, or at least a partial flap, that prevents the wheelchair from sliding out.

In an advantageous embodiment of the invention the at least one central module or the first lateral segment module comprises a second toilet arrangement with at least one toilet compartment. If the requirement in the particular vehicle tends to be for minimizing the design space occupied by galleys or storage compartments, it would be possible in this manner to be able to provide increased capacity for toilets in order to elsewhere in the cabin be able to do away with an independent toilet monument, and in this way accommodate additional passenger seats in this region that is becoming available. In this manner the economic efficiency of the vehicle can be further improved without having to do without necessary installations.

In a particularly advantageous variant the second toilet arrangement is arranged at a position facing the first toilet arrangement of the first lateral segment module. Not only does this make it possible to implement shared suction-removal of odors from these adjacent toilet arrangements, but it can also simplify the routing of suction lines and flushing lines, because the corresponding consumers in the form of the toilet arrangements are adjacent.

In an advantageous embodiment the second toilet arrangement extends over the entire width of the at least one central module. This means that the region between the first lateral segment module and the second lateral segment module could be taken up completely by a toilet arrangement comprising at least one toilet, a urinal or the like, if a single central module is provided. In this manner a number of toilets can be provided in a cabin segment in a cabin according to the invention, provided the design space within the cabin is sufficient for this, and consequently it is possible to do without a toilet monument in some other region of a passenger cabin, and instead of said toilet monument further passenger seats could be provided.

In an advantageous embodiment of the invention, the at least one central module comprises a parking space for at least one "half-size" cabin trolley as well as at least one storage compartment, wherein the cabin attendant seat is held on the at least one central module in such a manner that it can be pivoted in front of an access opening of the second toilet arrangement or in front of the storage compartment. Since the cabin attendant seat is a component that anyway is used relatively rarely and at other times merely "wastes" design space, it is very advantageous to pivot the cabin attendant seat in front of an access opening of the second toilet arrangement only in those phases where the use of the toilets is not desired anyway. In the case of aircraft, these phases are, in particular, the takeoff and landing phases. During the operation phases of the vehicle, in which phases the cabin attendant seat is not required, said cabin attendant seat can be pivoted on the central module, for example parallel to a direction of access to the second toilet arrangement, and consequently unhindered entry to the second toilet arrangement is possible, and the design space around this access opening is not blocked.

Furthermore, it is not mandatory for the individual modules of the cabin segment in the cabin according to the invention to be divided evenly in transverse direction; they can also, grouped according to the purpose of use, comprise projections, steps and indentations in transverse direction, which nonetheless make possible a composition to form an entire cabin segment. This means that, for example, at least part of an above-mentioned central module, which supports various functions, and a lateral segment module can be interconnected in the form of an enlarged lateral segment module. In this manner, for example, toilet compartments of a central module could be combined with toilet compartments of a lateral segment module. Furthermore, galley functions or storage compartments and parking spaces of a central module could be combined with similarly equipped lateral segment modules. In this manner one or two enlarged lateral segment modules could arise that can be combined to form one cabin segment. Separation of functions can simplify manufacture of the individual lateral segment modules.

In an advantageous embodiment the second toilet arrangement comprises a toilet compartment with a urinal, wherein the toilet compartment and the at least one storage compartment of the central module are arranged side by side in transverse direction. Such stringing together of functions within a single cabin segment module makes possible very space-saving integration of various functions, because the urinal requires only very little space when compared to a conventional toilet, so that the unoccupied design space could be taken up by a storage compartment arrangement.

In an advantageous embodiment of the invention, a partition wall is arranged between a first toilet compartment and an adjacent second toilet compartment, irrespective of the association with a lateral or central segment module. The partition wall may be fixedly arranged. It is preferred that the partition wall allows its later removal in order to replace the fixed partition wall with a movable partition wall. Thereby a modularity regarding the convertability of two separated toilet compartments to a larger, single toilet compartment is created.

In an advantageous embodiment the partition wall is movably held and is designed to be brought to an opening position in which separation between the first toilet compartment and the second toilet compartment is canceled. In this manner it is possible without further ado to create a toilet for the disabled, into which toilet a person in a wheelchair can drive and have enough space for accommodating the wheelchair.

In an advantageous embodiment of the invention, the partition wall is constructed from individual partition wall segments that are movably held. In this manner by means of easy pivoting or folding-over of partition wall segments an individual, larger toilet compartment can be created.

In an advantageous embodiment of the invention, a first partition wall segment is designed to be hinged to a first sidewall of the first toilet compartment, while the second partition wall segment is designed to be pivoted into a region that is not situated in the first toilet compartment or in the second toilet compartment. After moving into a thus formed j oint, larger, toilet compartment, the second partition wall segment can be pivoted back to the joint toilet compartment, for example in order to be used as a door or a cover flap.

In an advantageous embodiment of the invention, a direction of extension of the first toilet compartment and a direction of extension of the second toilet compartment are arranged so as to be essentially perpendicular to each other. This means that the first toilet compartment and the second toilet compartment together form an L-shape that is advantageous in particular for dividing the partition wall into two partition wall segments.

Furthermore, the object is met by a vehicle that comprises a cabin according to the invention. In particular, this vehicle can be an aircraft, thus providing significant advantages when compared to known aircraft from the state of the art.

<FIG> shows a lateral segment module <NUM> which in the preceding description was referred to as the second lateral segment module. It comprises an outer lateral face <NUM> and an inner lateral face <NUM> that delimit the second lateral segment module <NUM> in transverse direction or in horizontal direction. In this arrangement the outer lateral face <NUM> is shaped in such a manner that it can snugly fit to an inner wall of a cabin, and thus is designed so as to correspond to the aforesaid. In the example shown, the outer lateral face <NUM> is round, thus corresponding to one or several graduated circles of the fuselage of the corresponding vehicle. The inner lateral face <NUM> is planar and extends in vertical direction so that other modules can join while adapting to the inner lateral face <NUM>.

The second lateral segment module comprises a first parking space <NUM> and a second parking space <NUM> that are arranged in a lower half of the second segment module and that follow on from a base <NUM> that is positionable on a cabin floor. A parking space <NUM> arranged on the inner lateral face <NUM> is suitable for accommodating a cabin trolley <NUM>, wherein preferably also locking means (not shown in detail) can be arranged that prevent inadvertent releasing of the cabin trolley <NUM> from its parking space <NUM>. Preferably, the parking space <NUM> also comprises means for cooling or means for guiding a cold substance from a central device for proving a cooled coolant to the cabin trolley <NUM> so that food contained therein can be cooled during operation of the vehicle.

The parking space <NUM> facing the outer lateral face <NUM> is also equipped to accommodate a cabin trolley <NUM>, and preferably also to lock it. A further design characteristic of this outer parking space <NUM> could consist of providing adequate width to accommodate a wheelchair <NUM> in order to meet any operating regulations of providing in a vehicle, and in particular in an aircraft, the possibility of accommodating a wheelchair.

Since the second lateral segment module <NUM> adapts to an outer wall of a vehicle fuselage, and consequently the outer lateral face <NUM> is heavily curved, in the space between the outer parking space <NUM> and the outer lateral face <NUM> there is only relatively little design space, which in the present example is used by two storage compartments <NUM> and <NUM>. The upper of these two storage compartments <NUM> can, for example, accommodate various objects such as trays or elongated packages comprising food or auxiliary resources required on board the vehicle, for example a wheelchair ("onboard wheelchair").

By means of a horizontal intermediate floor <NUM> that extends in transverse direction, which horizontal intermediate floor <NUM> can be designed as a work surface, further storage compartments <NUM> of various sizes are partitioned off from the parking spaces <NUM> and <NUM> and can, in particular, be used for accommodating food that does not need to be cooled.

As an alternative to this, the compartments <NUM> arranged above the horizontal intermediate floor <NUM> or the work surface can be designed to accommodate various items of technical equipment which are, for example, used to heat food and drinks.

In <FIG> as an example a first central module <NUM> is presented that comprises a first lateral face <NUM> and a second lateral face <NUM>, which faces delimit the central module <NUM> in transverse direction. As an example, this central module <NUM> is designed, in particular, as a toilet module so that an access opening <NUM> to a toilet compartment <NUM> is arranged which can be closed by means of a door <NUM>. The toilet compartment <NUM> itself is of an L-shaped design, wherein a toilet <NUM> extends in transverse direction so that it is possible to use the remaining design space starting from a rectangular base <NUM> through a parking space <NUM> and compartments <NUM> arranged above.

To avoid excessively limiting the comfort within the toilet compartment <NUM>, the extension, in longitudinal direction, of the parking space <NUM> and of the compartments <NUM> is relatively short so that for example in an application in an aircraft only those cabin trolleys <NUM> can be inserted that comprise half the normal depth. Such cabin trolleys are referred to as half-size trolleys.

This illustration of the central module <NUM> shows that a cabin attendant seat <NUM> is provided that is pivotally held on the central module <NUM>. This cabin attendant seat <NUM> is discussed in detail later.

<FIG> shows a further exemplary central module <NUM> based on the same base <NUM>, except instead of an L-shaped toilet compartment <NUM> it comprises an essentially rectangular toilet compartment <NUM> extending in longitudinal direction, which toilet compartment <NUM>, however, comprises a urinal <NUM> instead of a toilet <NUM>. Said urinal <NUM> can be used with the person standing upright, and consequently significantly less space is required.

The design space that can be saved in comparison to the central module <NUM> of <FIG> can be utilized by additional depth of the parking space <NUM> or of the compartments <NUM> arranged above it. This makes it possible to park more than only one "half-size" cabin trolley <NUM>; for example a normal cabin trolley and a "half-size" cabin trolley could be arranged one behind the other in longitudinal direction, or alternatively three "half-size" cabin trolleys <NUM>. The same applies to the storage compartments <NUM>, which comprise three times the stowage volume of the central module <NUM> from <FIG>.

In particular when designing the cabin of a vehicle, the available toilet arrangements must be assessed because not every passenger requires a complete toilet compartment <NUM>; instead, by providing a urinal <NUM> with a significantly reduced toilet compartment <NUM>, adequate sanitary installations could be created that would result in significant savings of installation space.

If it is not necessary to equip the cabin segment with an excessive number of toilet arrangements, a central module <NUM>, as shown in <FIG>, could be used.

The central module <NUM> comprises a total of three parking spaces <NUM>, <NUM> and <NUM> in which cabin trolleys <NUM> can be parked. In this arrangement a parking space <NUM> extends further outwards in longitudinal direction than is the case with the two other parking spaces <NUM> and <NUM>, and consequently a cabin attendant seat <NUM> can be pivotally arranged on the resulting projecting wall. This design furthermore makes it possible to park two conventional cabin trolleys <NUM> in the parking spaces <NUM> and <NUM>, as well as a conventional cabin trolley <NUM> and a "half-size" cabin trolley <NUM> in the parking space <NUM>, or alternatively three half-size cabin trolleys if desired.

An intermediate floor <NUM> extends horizontally on the parking spaces <NUM>, <NUM> and <NUM>, where storage compartments <NUM> are arranged.

In the illustrated exemplary embodiment of the central module <NUM> the cabin attendant seat comprises a removable headrest part <NUM> that in a stowed position of the cabin attendant seat <NUM> can be removed or folded away in order to allow unrestricted access to the storage compartments <NUM>. When the cabin attendant seat <NUM> is required, it can be pivoted in front of the parking spaces <NUM> and <NUM> and can be equipped again with the removable headrest part <NUM>. While as a consequence of this the parking spaces <NUM> and <NUM> or the parking space <NUM> are blocked, this would, however, occur only at those times when no cabin trolley <NUM> is moved about, for example during takeoff and landing.

Furthermore, in the central module <NUM> shown, for the purpose of heating food an oven <NUM> is arranged which can be operated by way of a pivotally held flap that is useable as a work surface. When the cabin attendant seat <NUM> is pivoted into the free aisle in front of the module, it may be possible to do without taking off the headrest.

<FIG> shows a first lateral segment module <NUM> that comprises an outer lateral face <NUM> that is designed so as to correspond to the inner wall of the cabin in the provided installation location. In this variant the lateral segment module <NUM> comprises a toilet compartment <NUM> in which a toilet <NUM> is arranged that extends in longitudinal direction. In this manner with sufficient depth of the segment module <NUM> a conventional toilet function can be ensured. The inner lateral face <NUM> is of a planar design and extends vertically so that central modules <NUM>, <NUM> or <NUM> can follow on from it.

Finally, <FIG> shows a cabin attendant seat <NUM> with a headrest part <NUM> that could be designed so as to be removable if this appears to be necessary in a provided stowage position.

On one side <NUM> the cabin attendant seat <NUM> comprises a hinge <NUM> that need not necessarily extend over the entire height of the cabin attendant seat <NUM>. Said hinge <NUM> could also be positioned only in some locations over the height of the cabin attendant seat <NUM> in a manner similar to door fittings.

Furthermore, it should be added that the cabin attendant seat <NUM> is only shown diagrammatically; usually it comprises a fold-down seat surface and suitable seat belt and fastening means so that a cabin attendant can safely sit on said cabin attendant seat <NUM> and fasten the seat belt. Moreover, it should be mentioned that the pivotally held cabin attendant seat <NUM> must, of course, also comprise suitable locking means by means of which it can be held safely both in its stowed position and in its in-use position.

<FIG> shows a first exemplary embodiment of a modular cabin segment <NUM> for use in a cabin according to the invention that is shown as an example of the installation in a cabin of an aircraft. In this example the cabin segment <NUM> is located in a rear section of the aircraft cabin, in which a pressure bulkhead <NUM> is also arranged that normally at least in some sections corresponds to a spherical segment. This design space can normally not be fully used, but by arranging the cabin segment <NUM> in this region, for example in a toilet arrangement, it is possible to provide more space for users than is the case in conventional toilet monuments.

The exemplary embodiment shown is a combination of a second lateral cabin segment <NUM>, a central module <NUM> and a first lateral segment module <NUM>. Accordingly, in the variant shown, the cabin segment <NUM> comprises parking spaces for a total of <NUM>½ cabin trolleys, a row of storage compartments <NUM> and <NUM>, as well as two complete toilet compartments <NUM> and <NUM>.

As shown in the three-dimensional view of the cabin segment <NUM>, the parking space <NUM> of the central module <NUM> extends further into a cabin of the aircraft than does the toilet compartment <NUM> so that the resulting projecting wall <NUM>, which extends parallel to the longitudinal direction, is suitable for accommodating a cabin attendant seat <NUM>. In this arrangement the access opening <NUM> is somewhat narrower than the distance between the wall <NUM> and the inner lateral face <NUM> of the first lateral segment module so that the hinge of the cabin attendant seat <NUM> can be arranged on the resulting projection <NUM>, and at the same time the access opening <NUM> is not blocked. To use the cabin attendant seat <NUM> it can be pivoted to the entrance opening <NUM> so that the entrance opening <NUM> is blocked, which due to the infrequent times when the cabin attendant seat <NUM> is being used, and the concurrent undesirable use of the toilet, is unproblematic. As an alternative, pivoting in front of the adjacent parking space for a cabin trolley <NUM> would be imaginable and sensible, because the wall that delimits this parking space <NUM> is mechanically very strong. Furthermore, because of the mechanical strength the adjacent wall can particularly easily receive a locking means for locking the cabin attendant seat <NUM>. In this variant <NUM>½ cabin trolleys <NUM> can be accommodated.

<FIG> shows a further modification of a cabin segment <NUM>, in which apart from the second lateral segment module <NUM> a central module <NUM> with a urinal <NUM>, and a first lateral segment module that follows on from the aforesaid are used. In this arrangement, too, the cabin attendant seat <NUM> is arranged on a projection <NUM> and can be pivoted to an in-use position that blocks an access opening to the toilet compartment <NUM> or to the parking space <NUM>.

<FIG>, as an example, shows a further modification of a cabin segment <NUM> in which a second lateral segment module <NUM>, a central module <NUM> with parking spaces <NUM> to <NUM> and storage compartments <NUM>, as well as a first lateral segment module <NUM>, are used. While this variant only provides a single toilet compartment <NUM>, however, parking spaces for a total of <NUM>½ cabin trolleys <NUM> are provided, as are a large number of storage compartments for storing food or the like.

This illustration shows particularly clearly that one of the parking spaces <NUM> of the central module <NUM> extends significantly further into the cabin in longitudinal direction than do the other parking spaces <NUM> and <NUM> or <NUM>, and as a consequence it is very easy to provide adequate design space for the cabin attendant seat <NUM>.

Because of the arrangement of a multitude of storage compartments above the parking spaces for cabin trolleys <NUM>, it is desirable if the headrest part <NUM> of the cabin attendant seat <NUM> is designed so as to be removable.

In an in-use position the cabin attendant seat <NUM> can be pivoted to the parking spaces <NUM> and <NUM> or <NUM> so that the cabin trolley <NUM> situated therein can no longer be wheeled out. This is also unproblematic because during those times in which the cabin attendant seat <NUM> is in use, there is no service to passengers anyway, and the cabin trolleys are in place in their respective parking spaces <NUM> and <NUM>.

In the variant shown, the cabin attendant seat <NUM> is not arranged on a projection <NUM>; instead it blocks at least in part the parking space <NUM> of the end of the central module <NUM>, which end faces away from the lateral segment module <NUM>, so that the cabin trolley <NUM> can be removed from this parking space <NUM> only when the cabin trolley of the end facing the lateral module segment <NUM> has been wheeled out. This will be unproblematic when providing service to passengers on board the aircraft; in return, with this variant of the cabin segment <NUM> very strong integration of many functions, and in particular stowage space, are created.

With reference to <FIG>, it is at least diagrammatically described that part of the cabin segment <NUM>, <NUM> and <NUM> can be separated by a dividing curtain <NUM> from the rest of the cabin, wherein this dividing curtain <NUM> is particularly preferably arranged in the center and extends towards a cabin monument <NUM> spaced apart in longitudinal direction and can be guided by way of a curtain rod <NUM> or the like.

If in this cabin region further cabin attendant seats are necessary, they can be arranged in longitudinal direction on a partition wall or a monument opposite the cabin segment <NUM>, <NUM> or <NUM> as diagrammatically shown in <FIG> with the example of two cabin attendant seats <NUM> on a partition wall <NUM>.

<FIG> shows the variant of a cabin segment <NUM> from <FIG> with an alternative design of the segment modules required for this. Instead of coupling a second lateral segment module <NUM> to a central module <NUM> and a first lateral segment module <NUM>, at least from the point of view of production technology it may make sense to create a first lateral segment module <NUM> that exclusively comprises two toilet compartments <NUM> and <NUM> as shown in <FIG> and <FIG>. It is understood that instead of the toilet compartment <NUM> it is also possible to use a modification in the form of a toilet compartment <NUM> that comprises a urinal <NUM>.

In the exemplary embodiment shown, a second lateral segment module <NUM> could comprise the second lateral segment module <NUM> shown in <FIG> and a front part of the central module <NUM> that is arranged beside the toilet compartment <NUM> and that provides a parking space for a cabin trolley and storage compartments <NUM>. To it the cabin attendant seat <NUM> that can be pivoted is also affixed.

The variation of the arrangement of <FIG> for use with a urinal is shown in <FIG>. There a first lateral segment module <NUM> is shown which for the purpose of simplifying production steps comprises both a toilet compartment <NUM> with a toilet <NUM> and a toilet compartment <NUM> with a urinal <NUM>.

Likewise, a second lateral segment module <NUM> is shown which practically is a combination of the second lateral segment module <NUM> and the arrangement comprising a parking space <NUM> for a cabin trolley <NUM> and storage compartments <NUM> of <FIG> adjacent to the toilet compartment <NUM>.

In this arrangement the cabin attendant seat <NUM> is arranged on the second lateral segment module <NUM> where it can be pivoted.

<FIG> shows a further variant, in which a first lateral segment module <NUM> with a second lateral segment module <NUM> in the form of a second lateral segment module <NUM> of <FIG> combined with a central module <NUM> of <FIG> can be combined.

In the further course the optional convertibility of adjacent toilet compartments <NUM> and <NUM> is described in detail with reference to <FIG>. Said figures show a cabin segment from the preceding <FIG>, <FIG>, <FIG>, <FIG> or <FIG>, for the sake of simplicity, however, without any persons therein, as well as from a somewhat altered angle of view, and without a detailed illustration of the further integrated functions. The two toilet compartments <NUM> and <NUM> of the cabin segment, be it toilet compartments with a toilet or with a urinal, may always be separated by means of a fixed partition wall if the operator of the aircraft does not wish a convertability. In the shown embodiment the two toilet compartments <NUM> and <NUM> may be converted in a few simple steps and preferably without the use of tools, without the addition or removal of components, and without limitations during the flight, preferably by a flight attendant, to form an enlarged toilet compartment. Following the use of this enlarged toilet compartment the toilet arrangement can then be converted back to form two separate toilet compartments.

At first in <FIG> the first toilet compartment <NUM> is closed by a first toilet compartment door <NUM>. The second toilet compartment <NUM> is also closed by a second toilet compartment door <NUM>. Between the toilet compartments <NUM> and <NUM> there is a partition wall <NUM> comprising a first partition wall segment <NUM> and a second partition wall segment <NUM>. In the example shown the first partition wall segment <NUM> is held on a hinge axis <NUM>, and the second partition wall segment <NUM> is held on a hinge axis <NUM>. In the example shown the two hinge axes <NUM> and <NUM> are positioned so as to be spaced apart from each other; consequently, the partition wall <NUM> is designed as a double-wing door or a double door, and the region situated between the two hinge axes <NUM> and <NUM> forms the delimitation in longitudinal direction of the second toilet compartment <NUM>.

In order to connect the two toilet compartments <NUM> and <NUM> to form a joint toilet compartment, at first the first toilet compartment door <NUM> is opened outwards and away from the two toilet compartments <NUM> and <NUM> as indicated by an arrow in <FIG>. This takes place by means of a pivot movement of the first toilet compartment door <NUM> on a hinge axis <NUM> that is arranged on a delimitation wall of the first toilet compartment <NUM>.

Subsequently, as shown in <FIG>, the first partition wall segment <NUM>, after corresponding unlocking from a cabin floor and/or a cabin ceiling and/or the second partition wall segment <NUM>, is moved on the hinge axis <NUM> towards the pressure bulkhead <NUM> so that an opening arises between the first toilet compartment <NUM> and the second toilet compartment <NUM>. In this reached position it is particularly advantageous if the first partition wall segment <NUM> is locked, and consequently its position is determined until its renewed unlocking.

In a further step the second partition wall segment <NUM>, as shown in <FIG>, after unlocking from the cabin floor and/or from the cabin ceiling, is moved on the hinge axis <NUM> by approximately <NUM>° towards the outside so that as a consequence the first toilet compartment <NUM> and the second toilet compartment <NUM> are completely interconnected. In this position an opening <NUM> arises, through which, for example, a person sitting in a wheelchair <NUM> can effortlessly be moved, or move, into the now joint toilet compartment <NUM> (<FIG>).

After subsequent pivoting of the second partition wall segment <NUM> on the hinge axis <NUM> towards the opening <NUM>, separation of the joint toilet compartment <NUM> towards the outside takes place (<FIG>). The second partition wall segment <NUM> is correspondingly used as the new entrance door to the joint toilet compartment <NUM>. Furthermore, in this arrangement the first toilet compartment door <NUM> forms a sidewall of the entrance region to the joint toilet compartment <NUM>, which sidewall is arranged so as to be parallel to the direction of extension of the first toilet compartment <NUM>, of the second toilet compartment <NUM>, and at a distance from the second toilet compartment <NUM>.

In the shared toilet compartment <NUM> there is now adequate space for moving from the wheelchair <NUM> to a toilet seat or the like. If required, the joint toilet compartment <NUM> can be converted back to form two separate toilet compartments <NUM> and <NUM>.

It is thus evident to the average person skilled in the art that the partition wall segments <NUM> and <NUM> as well as the first toilet door <NUM> comprise at least one locking mechanism so that these elements can be locked in the various positions shown in <FIG>.

Likewise, it should be ensured that the new toilet compartment door <NUM> after conversion to form a larger toilet compartment is locked from the inside so as to prevent access by third parties. However, if required, it should be possible for a flight attendant to unlock at least one of the two toilet compartment doors <NUM>, <NUM> from the outside when help is required.

Finally, <FIG> shows an aircraft <NUM> with a passenger cabin in which as an example there is a cabin segment <NUM>, <NUM> or <NUM>.

Claim 1:
A passenger cabin for a vehicle (<NUM>) having a modular cabin segment (<NUM>, <NUM>, <NUM>) arranged in a rear section of the passenger cabin, in which a passage through the cabin segment (<NUM>, <NUM>, <NUM>) is not required, the cabin segment (<NUM>, <NUM>, <NUM>) comprising
- a first lateral segment module (<NUM>, <NUM>, <NUM>) that accommodates a first toilet arrangement with at least one toilet compartment (<NUM>), and
- a second lateral segment module (<NUM>, <NUM>, <NUM>, <NUM>),
wherein in each case an outer lateral face (<NUM>, <NUM>) of the first segment module (<NUM>, <NUM>, <NUM>) and of the second lateral segment module (<NUM>, <NUM>, <NUM>, <NUM>) is designed to snugly fit in each case to an inner wall of a cabin of the vehicle so as to correspond to the inner wall,
wherein the second lateral segment module (<NUM>, <NUM>, <NUM>, <NUM>) is a galley module,
wherein the cabin segment extends in a transverse axis from a sidewall of the cabin up to the opposite sidewall; and
wherein at least one of the modules (<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>) comprises at least one cabin attendant seat (<NUM>, <NUM>) that on one side is supported on the at least one module (<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>) so that it is pivotable on an axis.
