DETAILED DESCRIPTION

[0043] The following detailed description is merely illustrative in nature and is not intended to limit the embodiments of the subject matter or the application and uses of such embodiments. As used herein, the word “exemplary” means “serving as an example, instance, or illustration.” Any implementation described herein as exemplary is not necessarily to be construed as preferred or advantageous over other implementations. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0044] FIG. 1 shows a section of a passenger cabin 2 of an aircraft in a three-dimensional view, wherein a flight direction 4 is recognizable, which is directed forward for passengers. On a left side of the cabin 2, a first cabin monument 6 is illustrated, which comprises a first walling 8, which borders at a first aisle 9, as well as a second walling 10, which is covered in this view and borders at a second aisle 11 and encloses an angle α of exemplarily 90° with the first walling 8. The first aisle 9 and the second aisle 11 cross each other directly adjacent to the cabin monument 6 and thereby form an intersection 13. Both wallings 8 and 10 extend from a cabin floor 12 to a ceiling region 14 that delimits the passenger cabin 2 in an upward direction, and form a common outer edge 16, which protrudes into the cabin 2 and shows to the intersection 13.

[0045] A third, outer walling 18 runs along an edge of the first walling 8 that faces away from the second walling 10 and thereby follows an inner contour of an exemplarily cylindrically shaped aircraft fuselage through creation of a respective curvature, in which aircraft fuselage the passenger cabin 2 is created. It is to be understood that the cabin monument 6 may comprise a further, fourth walling or may be arranged at a walling of an adjacent equipment, such that in the cabin monument 6, a closed space 7 is created.

[0046] An arrangement 20 comprising the first cabin monument 6 comprises a blocking unit 22, which comprises a displaceable partition wall 24. Further elements, which fulfil a plurality of functions of the arrangement 20, are shown in further following figures in further detail.

[0047] The partition wall 24 is exemplarily displaceably supported along the flight direction 4 by means of two parallelly running rails 26 arranged in the ceiling region 14 above the cabin floor 12. In FIG. 1, the partition wall 24 is positioned in a first position, which is referred to as neutral position in the following and flushly or largely flushly connects to the first walling 8.

[0048] In FIG. 1, receptacles 28 that are integrated into a cabin door for receiving of emergency slides are recognizable. In the following the region of the cabin floor 12 between the receptacles 28 is referred to as door region 30, which is entered by passengers particularly during boarding and de-boarding.

[0049] In the first walling 8, a first access opening 32 is present, which allows a person to enter the first cabin monument 6 and which is closable by means of a first door 34. In the neutral position of the partition wall 24, the first access opening 32 is covered in such a manner, that opening the first door 34 from the door region 30 is not possible. The blocking unit 22 may consequently block the access through the first access opening 32 by means of the partition wall 24.

[0050] By moving the partition wall 24 on the rails 26 it may be brought from the neutral position into the second position, which lies within the door region 30, in such a manner, that the first access opening 32 and the first door 34 are released. The partition wall 24 may be displaced so far to passenger seats 36, which face to the arrangement 20, that between a leading edge 38 of the passenger seats 36 and the partition wall 24, a minimum distance given in certification regulations or requirements of an aircraft operator is met.

[0051] Through this design of the arrangement 20, the possibility is given to move passenger seats 36 as close to the door region 30 as possible, such that a space as large as possible for using passenger seats 36 within the passenger cabin 2 is usable. A separate, fixedly installed partition wall between the passenger seats 36 and the door region 30 resultantly is not necessary. For boarding and de-boarding, the partition wall 24 is moved in the neutral position shown here, such that sufficient space for entering the door region 30 exists. During the flight, the door region 30 does not need to be used for boarding and de-boarding, such that a partition wall 24 positioned there before flight does not disturb and the first access opening 32 is accessible.

[0052] The first cabin monument 6 may exemplarily comprise a lavatory, which should only be used during cruise flight. Blocking the first access opening 32 through the partition wall 24 therefore is reasonable in order to prevent the use during the boarding and de-boarding process and in order to provide a comfortable and non-constricting entrance.

[0053] Blocking the first access opening 32 through the partition wall 24 leads to one or a plurality of operation modes, in which the first access opening 32 remains unusable. In the previous section for the summary of the invention e.g. the second operation mode is mentioned, in which the use of the first access opening 32 is prevented.

[0054] FIG. 2 shows a top view onto the section of the passenger cabin 2 shown in FIG. 1. Here, in particular the second walling 10 having a second access opening 40, which is closable through a second door 42, is recognizable. The first door 34 and the second door 42 each are swivably supported on a vertical swivelling axis 44 or 46, respectively, at ends facing away from each other, wherein both doors 34 and 42 exemplarily commonly create the outer edge 16 and provide a corner entry with wider entry opening if opened simultaneously. In the neutral position of the partition wall 24 with unblocked access to the second aisle 11 as well as unblocked second door 42, an access is possible through the second access opening.

[0055] An access to the second access opening 40 or the second door 42, respectively, from the door region 30 may be prevented through a further blocking means in form of a curtain 48. For this purpose, the curtain 48 is arranged at a second cabin monument 50, which is adjacent to the second aisle 11 and opposed to the first cabin monument 6. The curtain 48 thereby is exemplarily supportable at a side of the second cabin monument 50 facing away from the first cabin monument 6. In a position, in which the second access opening 40 is blocked, the curtain 48 extends to the outer edge 16 and consequently closes the second aisle 11. Entering the second aisle 11 is therefore impossible, such that this may be used for work tasks at the second cabin monument 50, e.g. for preparing of meals.

[0056] As furthermore shown in FIG. 3, the partition wall 24 may be distanced from the first walling 8 in such a manner, that the partition wall 24 is placed in the door region 30 and entering the first cabin monument 6 behind the partition wall 24 through the first access opening 32 and the door 34 is allowed. In this context it is reasonable to block the second door 42 through a blocking means, which is exemplarily integrated into a fitting assembly 52, such that a user cannot enter the second aisle after walking through the first access opening 32. As an alternative, separate blocking means, exemplarily in form of a bar 54, are conceivable, which allow a blocking of the second door 42 independently from the fitting assembly 52. The arrangement 20 is illustrated in FIG. 3 in such a manner, that the blocking unit 22 is in a first operation mode. The access to the first access opening 32 is possible in an unrestricted manner, while the access through the second access opening 40 is blocked.

[0057] The clear distance between the partition wall 24 and the leading edge 38 of the passenger seats 36 facing the door region 30 hereby conforms the requirements of the aircraft operator or of possible certification regulations, such that passengers on these passenger seats 36 have a sufficient leg room. Since anyway the door region 30 is not usable for boarding and de-boarding during flight, the partition wall 24 does not disturb in this region. As further apparent from FIG. 3, the partition wall 24 may be held by means of an additional rail system 56 in a region near the floor, such that separate fastening means at the cabin floor 12 are not necessary.

[0058] For entertaining the passengers on passenger seats 36 facing into the door region 30, the partition wall 24 may carry a screen 58 or other devices, which are supplied through electrical lines in the upper rail 26 or the lower rail 56.

[0059] FIG. 4 shows the constellation of FIG. 3 in a top view. Exemplarily, the first door 34 is supported at the common outer edge 16 through a hinge, such that an access to the first access opening 32 should be accomplished primarily from a radially outer region of the cabin 2. The outer edge 16 may hereby be designed rigidly and may receive an end of the curtain 58 mechanically simply through suitable means. The second door 42 may, if it is released, be swivelled around the outer edge 16, too.

[0060] In an alternative variant, the first door 34 and the second door 42 each may be supported around the hinge axis 44 and 46 at ends facing away from each other, such that both, if opened, allow a wider access to the first cabin monument 6. Hereby, it is particularly possible for disabled persons to pass into the first cabin monument 6 by means of a wheelchair. The blocking unit 22 in the case shown in FIG. 5 is in a third operation mode, which allows the access to both access openings 32 and 40.

[0061] As shown in FIG. 6 in a top view, a width 60 of a common access opening 62 is clearly larger than that of the first access opening 32 or of the second access opening 40.

[0062] FIG. 7 shows a modified embodiment of a partition wall 64 instead of a curtain 48 as a blocking means for blocking the second aisle 11, which has the same features as the partition wall 24 but additionally is equipped with a dimensionally stable barrier 66, which is extendable and retractable parallelly to an extension plane of the partition wall 64. Through extending the barrier 66, the second aisle 11 resultantly may be blocked. As shown in FIG. 8, an unhindered use of the cabin monument 6 through a vehicle operator or other crew members is selectively allowed, if the second door 42 is usable.

[0063] As shown in all illustrations, the arrangement 20 may be placed in a forward region facing the nose of the aircraft, wherein a cockpit door 68 between both monuments 6 and 50 are accessible from the cockpit from the second aisle 11. For staying in the cabin monument 6 undisturbedly as well as to prevent entering the second aisle 11 when the cockpit door 68 opens, the barrier 66 may block the access to the second aisle 11, as recognizable in particular in FIG. 8.

[0064] As also apparent in all figures, the number of the passenger seats 36 reaching into the door region may be limited to four, which on the one hand facilitates entering the passenger cabin from a cabin door opening as well as entering a center aisle 70.

[0065] In addition, it should be pointed out that “comprising” does not exclude other elements or steps, and “a” or “an” does not exclude a plural number. Furthermore, it should be pointed out that characteristics or steps which have been described with reference to one of the above exemplary embodiments may also be used in combination with other characteristics or steps of other exemplary embodiments described above.
