the following detailed description is merely exemplary in nature and is not intended to limit the present disclosure or the application and uses of the present disclosure . furthermore , there is no intention to be bound by any theory presented in the preceding background or the following detailed description . in fig1 a , a passenger seat is shown with a seating 12 , a backrest 14 , which can be movably connected to each other . here , an example is shown , where conditioned air is supplied through a passenger service module 16 to a passenger sitting , for instance , in a seat behind the shown seat . the passenger service module is supplied with conditioned air through a passenger service module supply line 20 , which has a second end 26 positioned at a side plane of the seating 12 and connected with an interface 24 . instead of conditioned air , any other passenger service can be supplied analogously , which means , that the passenger service module 16 has to provide the respective service in an appropriate manner . for example , the passenger service module for access to a data network can be a suitable socket instead of the shown air outlet of this example . the interface 24 and the passenger service module supply line 20 are integrated into the seating 12 . the supply line 20 thereby extends from its first end 22 across the backrest 14 and the seating 12 to the second end 26 and is there connected to the interface 24 . the passenger service module 16 can , in difference to the shown arrangement in the backrest 14 , also be located in any other part of the backrest or any other part of the passenger seat . for example , it can be possible to dispose one or more passenger service modules in an armrest ( not shown ). fig1 b shows another example of a passenger seat 10 with a seating 12 , a backrest 14 and multiple passenger service modules 16 . in more detail , the passenger service modules 16 comprise a passenger air outlet 36 , a passenger light 38 , passenger oxygen 34 , passenger buttons 42 , and information signs 40 . all shown passenger service modules 16 are arranged on a rear side of the backrest 14 . through suitable arrangement all passenger service modules are easily accessible by a passenger sitting in a row behind the passenger seat 10 . the shown passenger service modules are supplied by several passenger service module supply lines 20 , which are connected to an interface of the passenger service module supply lines 24 . in the shown example , an air pipe interface of the passenger service module supply line 28 and an electric interface of the passenger service module supply line 30 are shown . the arrangement of supply lines and interfaces can be displaced within a seating opening 32 . therefore , a horizontal position of the interface of the passenger service module supply line 24 is variable on a substantially horizontal line across the opening 32 in the seating 12 . the information signs 40 can contain information about flight status , seatbelt signs , phone usage , smoking , and others . the passenger buttons 42 can allow switching of lights , flight attendant call or other functions . the passenger service module supply line 20 can also serve multiple passenger service modules for a plurality of seats , which are interconnected , as shown in fig1 b . the seating opening 32 can also be arranged below the backrest 14 in the seating 12 . fig2 shows a cross - sectional view of an aircraft fuselage 50 , comprising an aircraft cabin 52 , a cargo area 54 , a central supply line 56 , connecting branches 58 of the central supply line 56 , cabin wall segments 60 , an outer wall 62 , and rows of overhead bins 64 . the wall segment 60 comprises several interfaces 66 of the central supply line 56 , which are arranged approximately in the same height over the cabin floor 53 . each interface 66 may be connected to the central supply line via a respective connecting branch 58 . as it can be seen in this example , multiple seats can be supplied with services via one interface 66 of the central supply line . the central supply line 56 is shown here as a cross - sectional view and can be provided as tube or , in case of electric services , it can be a cable channel or similar . the connecting branches 58 allow accessing the central supply line 56 for one individual seat 10 or seat row by connection through a vertical side plane of the seating 12 . an advantage can be that due to their size , the central supply line 56 can be disposed , for instance in the or near the cargo area 54 or the lower part of the aircraft fuselage 50 . fig3 shows a top view of an aircraft cabin 52 with a seat 10 or a seat row , multiple seatings 12 , connecting branches 58 of a central supply line 56 ( not shown ), several interfaces 66 of the central supply line , wall segments 60 , and several passenger service module supply lines 20 . the central supply line 56 ( not shown ) extends , for instance as an air tube or cable channel across the aircraft fuselage and may comprise vertical branches 56 , which reach to an area near the seats for individual connections . the seats 10 and the wall segments are positioned close to each other to achieve short distances between the cabin wall segments 60 and the seating 12 . the second end of the passenger service module supply line 20 can be displaced along a horizontal distance within the seating 12 . this way , for all positions of the second end 26 of the passenger service module supply line 20 always a corresponding interface 66 of the central supply line 56 is available on the same horizontal position . therefore , in any layout and seating configuration , a direct connection between the seat 10 , in particular the passenger service module supply line 20 , and the central supply line 56 can be established . in other words , the horizontal distances and positions of the interfaces 66 of the central supply line in the cabin wall segment 60 in combination with the displaceable interfaces 24 of the passenger service module supply lines may provide higher flexibility in terms of any possible cabin seating layout . fig4 shows a vertical cross - sectional view of an aircraft cabin 52 comprising multiple passenger seats 10 with a seating 12 and a backrest 14 . furthermore , also here , a central supply line 56 with connecting branches of the central supply line 58 and corresponding interfaces 66 of the central supply line are shown . the connecting branches 58 are equally distanced from each other in a horizontal direction . furthermore , the interface 24 of the passenger service module supply line is displaceable along the opening 32 of the seating 12 . depending on the positioning of the passenger seats 10 , in particular the distance between two neighboring seats or seat rows 10 , not all connecting branches 58 and interfaces 66 of the central supply line may be used . unused interfaces 66 may be covered to be protected from damaging . the horizontal position of the interface 24 of the passenger service module supply line may vary depending on the position of the interface 66 of the central supply line and extends orthogonally to a surface of the cabin wall segment 60 . fig5 shows a simplified view of a cabin wall segment 60 , comprising window openings 68 and interfaces 66 of the central supply line . the interfaces 66 of the central supply line are arranged along a horizontal line with equally the same distance . the horizontal distance 70 can be , for example about 12 . 5 inches or 31 . 75 cm . a length 74 of the cabin wall segment can be about 50 inches or 127 cm . the interfaces 66 of the service supply line are , in this example , equally distanced in horizontal direction . while at least one exemplary embodiment has been presented in the foregoing detailed description , it should be appreciated that a vast number of variations exist . it should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples , and are not intended to limit the scope , applicability , or configuration of the present disclosure in any way . rather , the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment , it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the present disclosure as set forth in the appended claims and their legal equivalents .
