Abstract:
A partition wall for integration into the vehicle cabin of a transportation means comprises a first surface and a second surface, which are arranged parallel to each other. The first surface comprises at least one recess, which may be filled with an at least regionally flat body designed correspondingly thereto, wherein the body is pivoted to the body by means of a swivelling means and may be brought into a stowed position and use position. The body fills out the accompanying recess when in its stowed position. This yields a multifunctional partition wall that may tangibly increase the comfort and available space on board the transportation means without taking up additional installation space.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This is a continuation of International Application No. PCT/EP2014/066290, filed Jul. 29, 2014, which application claims priority to European Application No. 10 201 108 121.5, filed Jul. 30, 2013, which are hereby incorporated by reference in their entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    The embodiments herein relate to a partition wall for integration into a cabin of a transportation means, a monument arrangement in a cabin of a transportation means, and a transportation means with a cabin along with at least one such partition wall arranged therein. 
       BACKGROUND 
       [0003]    In addition, other objects, desirable features and characteristics will become apparent from the subsequent summary and detailed description, and the appended claims, taken in conjunction with the accompanying drawings and this background. 
         [0004]    When setting up passenger cabins, an essential objective is often to maximize the available number of passenger seats, which is limited by the number of prescribed seats for crewmembers, and by prescribed safety installations, utility installations and toilets. The economic viability of an aircraft, for example, also depends on the ratio between the number of passenger seats and other installations. Apart from elementary installations like vehicle attendant seats and toilets, providing a desired comfort level also requires that beverages and meals for the passengers be carried on board a transportation means. The space this takes up should place as little restriction as possible on the space available to the passengers, so that the highest number of passengers may be transported while still providing a certain level of comfort. 
         [0005]    WO 2011/101385 A1 shows an especially space-saving toilet arrangement for a transportation means with a first toilet room, a second toilet room adjacent thereto, and a partition wall located between the first toilet room and second toilet room, wherein the partition wall is movably mounted and set up to be moved into an open position in which a separation between the first toilet room and second toilet room is eliminated. Despite the limited construction volume, two relatively small toilet rooms may thereby be converted into a larger toilet room suitable for use by individuals with limited mobility. 
       SUMMARY 
       [0006]    It is an object to provide a passenger cabin in a transportation means so as to make the installation space for necessary devices even more compact in order to increase the space available for passengers. 
         [0007]    This object is achieved by a partition wall for integration into the cabin of a transportation means. Advantageous embodiments and further developments may be gleaned from the claims and following description. 
         [0008]    Proposed is a partition wall for integration into the cabin of a transportation means that comprises a first surface and a second surface arranged parallel to each other, wherein the first surface has at least one recess is Tillable with an at least in some regions flat body designed correspondingly thereto. The body is secured to the partition wall so that it is pivotable by way of a swivelling means, and is bringable into a stowed position and use position. When in its stowed position, the body fills out the accompanying recess. 
         [0009]    As opposed to the partition walls common in prior art in the cabins of transportation means, which are spaced a certain distance away from door areas or monuments, for example galleys, and configured as a flat, single piece, the partition wall according to the embodiment is a multifunctional partition wall able to perform any other functions desired aside from the actual partition wall function. In conceiving the partition wall according to the embodiment, it is assumed that the second surface faces a passenger area with passenger seats, while the first surface faces a cabin monument, a door area, a stair or the like, i.e., cabin areas that are not primarily used by passengers during normal operation of the transportation means. It is especially preferred that the visible part of the second surface comprise a uniform, closed and flat surface, which may be equipped with passenger-related devices if so desired. Examples include screens for an onboard entertainment system (in-flight entertainment, IFE), baby tubs or even just magazine holders. By contrast, the first surface may be equipped with a large number of various devices, which are to be pivoted to the partition wall. In this way, additional functions otherwise intended only for other monuments may be installed in the most compact space possible, and stowed in a space-saving manner on the wall when not in use. In particular, the body may be shaped like a plate, which has contours adjusted to serve a specific purpose, and may be positioned at a suitable height. 
         [0010]    The swivelling means may include a first swivelling means and a second swivelling means, wherein the first swivelling means may be situated on the respective body, and the second swivelling means may be situated on the partition wall or recess. The first and second swivelling means then comprise a hinge, and permit a pivoting around a hinge axis determined by this hinge. It is of course possible to have other swivelling means that realize a different type of pivoting with rotary and/or translational moving portions. 
         [0011]    In an particularly preferred embodiment, the body fills out the accompanying recess in a flush manner when in its stowed position. As a result, the first surface is preferably completely even or smooth. 
         [0012]    Furthermore, the partition wall may also comprise at least one locking means, which is set up to securely hold the body in the accompanying recess when in the stowed position. The locking means may comprise positive and non-positive devices that permit a reliable connection at the loads to be expected during operation of the transportation means, which stem in particular from inertial forces. Examples include latches, clips, catches, clamps and Velcro fasteners. 
         [0013]    In a preferred embodiment, the first surface of the partition wall comprises a first recess and an accompanying first body is a swivelling tabletop situated in the first recess. The partition wall further comprises at least one locking means for retaining the tabletop in a stowed position. If needed, a table, for example one that serves a vehicle attendant, may be provided by detaching the at least one locking means and swivelling the tabletop out of a stowed position into a use position. In the stowed position, the tabletop is preferably arranged flush in its recess, and may be held in this position by the at least one locking means. The first surface of the partition wall is preferably completely even and smooth in this stowed position. As a result, integrating the tabletop into the partition wall by swivelling it back into the stowed position does not impede individuals who are present/working in or passing through an area facing the first surface of the partition wall. Tabletop integration requires no additional installation space on other monuments, and thus constitutes an especially space-saving way of providing an additional useful function. 
         [0014]    In an advantageous embodiment, the tabletop is pivotable around a hinge line on the first surface of the partition wall, wherein the hinge line is preferably horizontally aligned. The tabletop assumes the table function by simply being swivelled out of a perpendicular position around the hinge line into a horizontal position. Of course, the height of the hinge line may also be selected based on ergonomic criteria. Given a more complex configuration of the swivelling means, however, the hinge line may also be aligned vertically or at a general angle relative to the horizontal if a sequence of several rotational pivoting motions is possible. For example, the tabletop could first be rotated around a vertical swivelling axis, and subsequently be rotated around a horizontal swivelling axis situated perpendicular to the first surface. The at least one locking means should then be capable of also detachably blocking the horizontal position. 
         [0015]    In addition, it may be beneficial to arrange at least one locking means on a side of the first recess lying opposite the hinge line. As a result, a reliable retaining function for the tabletop may be achieved at the lowest possible holding force and utilizing the greatest possible distance from the hinge line. 
         [0016]    It is further preferred that a retaining support that supports the tabletop in the use position be located at a position of the tabletop spaced apart from the hinge line. The retaining support is thereby preferably pivoted to the tabletop, and may assume a perpendicular alignment relative to the tabletop. If the tabletop is perpendicular to the partition wall in the use position, a properly dimensioned retaining support may allow a secure footing on the cabin floor in a perpendicular position relative to the tabletop. 
         [0017]    The hinge line for the tabletop may be oriented in such a way as to reach the usual working height, which ranges between about 70 and 80 cm from the cabin floor. However, the height may also be varied by allocating the tabletop and/or first surface of the partition wall according to the embodiment to a vehicle attendant seat situated on a monument lying opposite the partition wall. The height of the hinge line for the tabletop should then be adjusted to the seat height of the respective vehicle attendant seat. 
         [0018]    In an advantageous embodiment, a second body is a seating surface pivotably arranged around a hinge line on the first surface of the partition wall and bringable from a stowed position into a use position. The seating surface could here be configured similarly to the tabletop described above, and is allocated to a second recess on the first surface. The respective hinge line is preferably horizontally arranged, and thus makes it possible to stow the seat with which a seating surface may be created in a vertical position, and swivel the seating surface into a horizontal position for use. 
         [0019]    Since a seating surface is usually subjected to a higher load than a tabletop, it may also be advantageous to pivot at least one retaining support to the seating surface. When the seating surface is swivelled out of a vertical stowed position into a horizontal use position, the retaining support of the seating surface may be folded out, so that the seating surface is securely held between the hinge line and retaining support in a horizontal position. Alternatively or additionally, the seating surface is situated in a frame, which introduces the load as uniformly as possible into the partition wall. 
         [0020]    The partition wall according to the invention preferably comprises both a pivotably supported tabletop and a pivotably supported seating surface. As a consequence, a seat and table may be provided when necessary out of a smooth, even partition wall, for example which may be utilized by personnel inside the transportation means during breaks or to make notes. 
         [0021]    In just as advantageous an embodiment, a third body is designed as a swivelling clamp mounting for retaining objects that are positionable on the first surface, which fills a third recess when in the stowed position. A lockable or retainable object has an upper surface onto which the clamp mounting may be swivelled or folded open. As a consequence, the height of this upper surface should correspond with the height of a lower surface of the clamp mounting, so that clamping may take place. It may be advantageous for the clamp mounting to comprise an elasticity that allows a secure retention of objects that run under the lower surface of the clamp mounting and have a certain height tolerance. For example, if the object to be retained is a bit too high, the elasticity of the clamp mounting allows it to also be swivelled or folded onto the upper surface of the object. It is further advantageous to arrange a compressible body on the lower side of the clamp mounting, which is compressed when applied to the upper surface of the object, and improves the retention of the object due to the repelling force caused by the compression. It especially makes sense to provide a body comprised of an elastic material for this purpose, for example an elastomer like rubber, gum elastic, or silicone. It may also make sense to provide a retaining plate, which may be placed on the object to be retained and subsequently fixed in place with a locking device. 
         [0022]    The clamp mounting is especially suited for at least temporarily retaining trolleys on the partition wall according to the invention, for example when a galley module with a highly compact configuration and the capacity to store several trolleys situated one behind the other in a mounting shank requires that a trolley be removed from a mounting shank and be temporarily stored for a short time at another location. 
         [0023]    In another embodiment, the partition wall may comprise at least one cut-out, as well as at least one storage compartment that corresponds with the cut-out, is situated on the second surface of the partition wall and is accessible from the first surface by way of the cut-out. The partition wall in the cabin of a transportation means may extend from a floor up to ceiling area, and thus also cover those areas not accessible to passengers in the transportation means. Let it be noted strictly by way of example that overhead storage compartments may be situated above the passenger seats and be used for luggage, utensils or oxygen tanks. A cut-out in the partition wall according to the invention could be located in an area that borders a storage compartment or a cover panel that adjoins a storage compartment, for example. A storage compartment accessible from the first surface could here be provided, which is used in particular by personnel on board the transportation means. For example, emergency equipment may be integrated in a flush manner instead of being bolted to or on the wall. The cut-out through which the storage compartment is accessible may be designed as an orifice to which a sealing cap may be secured to closet the storage compartment. 
         [0024]    The partition wall may basically be fabricated out of any material. However, the ability to provide a certain thickness is advisable to ensure the various functions, so that a tabletop or other pivoted devices close flush with the first surface of the partition wall when in a stowed position. A lightweight structure lends itself precisely to integration into transportation means and in particular into aircraft, for example realized as a sandwich design, and apart from cover layers with an interspersed core layer may also comprise a frame structure with a lattice-like frame lying on the inside. In particular in framework designs, it is recommended that the contours of the respective recesses be surrounded by frame components so as to ensure the greatest possible strength. Precisely during the integration of a seating surface, the load introduced by the seating surface may be ideally introduced into the partition wall in this way. When configuring the second surface of the partition wall, it makes sense to use a continuous cover layer that closes off any recesses on the first surface. During the integration of hinge elements into honeycomb layers, local reinforcement should be ensured via a frame component or by incorporating a larger-surface component preferably consisting of a massive material. 
         [0025]    The embodiments described herein further relate to a monument arrangement in a transportation means. The monument arrangement comprises a partition wall described above along with a monument facing the first surface of the partition wall and spaced apart from the latter, for example which may be designed as a cooking monument or toilet, alternatively as a modular monument with kitchen and/or toilet modules as well. It is especially preferred that the monument comprise a vehicle attendant seat, the seating surface of which may swivel. The vehicle attendant seat is preferably located in an area of the monument that faces the tabletop of the partition wall that may swivel out. This is intended to ensure that a vehicle attendant who sits down on the vehicle attendant seat secured to the monument may take a seat at the tabletop secured to the partition wall when folded out. A swivelling seating surface on the partition wall should further be spaced laterally apart from the optionally present seating surface. It is especially preferred that the monument comprise at least one parking space for a trolley, which may be taken out of the parking space and retained under a clamp mounting pivoted to the partition wall. It is especially preferred that the monument arrangement according to the invention encompasses a galley monument with at least one storage compartment, and oppositely thereto a partition wall according to the invention. 
         [0026]    The embodiments further relate to a transportation means with a cabin and a partition wall situated therein, wherein a monument arrangement of the kind described above is preferably included. The transportation means is here in particular a commercial aircraft.

     DETAILED DESCRIPTION 
       [0032]    The following detailed description is merely exemplary in nature and is not intended to limit the disclosed embodiments or the application and uses thereof. Furthermore, there is no intention to be bound by any theory presented in the preceding background detailed description. 
         [0033]      FIG. 1  shows a partition wall  2  in the cabin  4  of a transportation means. The partition wall  2  comprises a first surface  6  and a second surface  8 , which are arranged parallel to each other. While the first surface  6  is clearly discernible in the drawing plane, the second surface  8  is covered in this case. The partition wall  2  is located on the floor  10 , where it is anchored by suitable means, and extends perpendicularly into the cabin  4 . A perpendicular bordering edge  12  bounds the partition wall  2  in a horizontal direction, and there bounds a passage  14 . Situated in a laterally opposite position at the passage  14  is a second partition wall  16 , which also comprises a lateral bordering edge  18  that bounds the other side of the passage  14 . The partition wall  16  may correspond to the partition wall  2 . The edges of the partition walls  2  and  16  spaced apart from the passage  14  are preferably adjusted to the inner contour of the cabin  4  in the transportation means. 
         [0034]    The partition wall  2  is situated in the cabin  4  in such a way as to close off a passenger area  20  in a longitudinal direction in the cabin  4 . Therefore, the second surface  8  is oriented toward the passenger seats  22 . The distance away from the passenger seats  22  is selected in such a way that backrests  24  may be swivelled into a relaxed, semi-prone position. Let it here be noted that, while the second surface  8  points toward the backrests  24  of the passenger seats  22  in the example shown, a configuration in which the second surface  8  is directed toward the front side of the passenger seats  22  would also be possible. However, the example shown now relates to the rear area of an aircraft, as evident from the partially depicted pressure bulkhead  26 , which bounds the usually pressurized cabin  4  in a commercial aircraft from the rear. 
         [0035]    The special feature of the partition wall  2  lies in the fact that it not just acts as a partition wall, but also performs other functions usually not handled by partition walls. The first surface  6  comprises a first recess  28  in which a first body is situated in the form of a tabletop  30  and may be swivelled by way of a hinge line  32 . For this purpose, the tabletop  30  comprises first swivelling means, which engages into second swivelling means on the first surface  6 , and thereby forms a kind of hinge. The resultant hinge axis  32  is horizontally situated, so that the tabletop  30  may be folded from an essentially perpendicular stowed position into an essentially horizontal use position. Located at an end of the first recess  28  remote from the hinge line  32  are locking means  34 , which are designed as latches or the like. Arranged between the two locking means  34  is a hinge  36  bearing a retaining rod  38 . With the tabletop  30  folded out, the retaining rod  38  may reliably support the end of the tabletop  30  facing away from the hinge line  32  on the floor  10 . 
         [0036]    When in the stowed position, the tabletop  30  is flush with the second surface  6 , so that it does not influence how the area in front of the second surface  6  is used in any way. Nevertheless, the additional function of the tabletop  30  ensures that valuable installation space is not wasted anywhere. 
         [0037]    For example, the first surface  6  accommodates a second body in the form of a seating surface  40 , which may also be swivelled out of a second recess  44  via a horizontal hinge line  42 . The height of the hinge line  42  measured from the floor  10  is less than the height of the hinge line  32 , so that the tabletop  30  may be used when sitting on the seating surface  40 . Given the higher load on the seating surface  40  when used by an individual, the seating surface  40  may be embedded into a frame  62  fixedly integrated into the partition wall  2  (see further below), and/or comprise an outwardly folding or telescoping retaining support, which just as the retaining support  38  of the tabletop  30  provides a reliable support on the floor  10  or frame  62 . 
         [0038]    Further depicted is a clamp mounting  46  that is exemplarily situated right next to the tabletop  30  in a third recess  47 , and may pivot at least partially around a perpendicular hinge axis  48 . The objective of this clamp mounting  46  is to clamp an object that may be positioned flush against the first surface  6  and comprises a height making it possible to slide or clamp on a lower edge  51  of the clamp mounting  46 . As will be described further below, the clamp mounting may be enhanced by a retaining plate  68  that may swivel around a horizontal hinge line. Relative movements by the object may be reliably prevented by the clamp mounting  46 , for example so that a trolley or the like may temporarily be left under the clamp mounting  46  against the partition wall  2 , and the trolley may be prevented from inadvertently moving away. 
         [0039]    The alignment toward the backrests  24  of the passenger seats  22  easily makes it possible to provide a stowage space in the form of standardized storage compartments  50  at a lower end of the partition wall  2 . To this end, the first surface  6  comprises cut-outs  52  through which the storage compartments  50  may be reached. The latter extend under the backrests  24  of the passenger seats  22 , and have absolutely no effect on how the passenger seats are used. For example, two standardized storage compartments  50  are located at a lower end of the partition wall  2 . 
         [0040]    Since the partition wall  2  in the cabin  4  may extend from a floor  10  to a ceiling cover panel (not shown), it may also be used as a lateral boundary for overhead storage compartments  54  or their adjoining cover panels  56 . For example, the first surface  6  incorporates another cut-out  58  leading to another standardized storage compartment  50 , which is situated at an upper end of the partition wall in a cover panel  56  adjacent to an overhead storage compartment  54 . As a result, a partition wall  2  permits the accommodation of three standardized storage compartments. More storage compartments may be used depending on the expanse of the cabin  4 . 
         [0041]    As evident from the depiction on  FIG. 1 , the first surface  6  has facing it a monument  59 , on which is positioned an attendant seat  60 , for example one that may swivel. The position selected for the tabletop  30  on the partition wall  2  is such that the tabletop  30  may be used from the attendant seat  60  when folded out. Combined with the foldout seating surface  40 , two attendants may thus use a tabletop together without even taking up additional installation space. By comparison to known configurations of monuments and partition walls, this is highly advantageous, since the worktops in a kitchen module would otherwise be diverted from their intended use, and could impede ongoing operations there. In addition, the level of comfort for attendants on board a transportation means is clearly improved, since enough space for shorter breaks is provided. 
         [0042]      FIG. 2  shows a folded out seating surface  40  along with a folded out tabletop  30  from a somewhat modified perspective. The retaining support  38  in this depiction may still be discerned at least at the lower end, and demonstrates that the tabletop  30  is securely held in place, being supported on the floor  10 . Also visible is that the seating surface  40  is arranged on a stable frame  62 , which is flatly integrated into the recess  44  of the partition wall  2 . For example, the partition wall  2  may consist of a frame structure (not shown), which is integrated into the frame  62  of the seating surface  40 . As a result, especially advantageous loads may be introduced from the vehicle attendant seat  40  into the partition wall  2 . 
         [0043]      FIG. 3  shows how two individuals sitting on the vehicle attendant seat  60  and seating surface  40  use the tabletop  30 , also from a modified perspective. The tabletop  30  is here dimensioned in such a way that both individuals may very easily use it at the same time. As also evident from the depiction, even though the narrow gap between the monument  59  and partition wall  2  wastes no space, an especially comfortable spot may still be provided for breaks or seated activities. 
         [0044]    Finally,  FIGS. 4A and 4B  show the use of the partition wall  2  for temporarily retaining a trolley  64  that is located in the monument  59 , but must be temporarily stowed on the partition wall  2  to free up a space lying behind it.  FIGS. 4A and 4B  show two different perspectives for this purpose. 
         [0045]      FIG. 4A  shows the trolley  64 , which is arranged in a receiving space  66  of the monument  59 . This trolley  64  is parked in this position only during flight phases in which no access to the toilets is allowed, i.e., during turbulence. In the case of turbulence, it is important to secure the trolley  64  as quickly as possible. The function makes sense, since the trolley  64  might here be one from another galley for which no storage space is provided in the galley depicted. During turbulence, it might not be possible to move the trolley directly to the accompanying galley, so that the trolley may be reliably secured until the turbulence has passed. 
         [0046]      FIG. 4B  shows the clamp mounting  46 , which consists of a clamping plate  68  that may be accommodated in the third recess and comprises a downwardly directed protrusion  70 , which extends over the trolley  64 , and of a locking device  72  that may be essentially horizontally swivelled around a hinge axis  48  and in so doing presses the clamping plate  68  onto an upper surface  76  of the trolley  64 . As a result, the trolley  64  may be reliably held in its current position, and not drift away from the partition wall  2 , whether laterally or in the longitudinal direction. 
         [0047]    Therefore, the partition wall  2  according to the embodiment is an especially advantageous, multifunctional partition wall that tangibly increases the comfort and available space on board a transportation means. As a result, especially favorable configurations of monuments and a partition wall may be provided in a transportation means, leading to a substantial upgrade to the cabin.
