Transition for a sidewall to a monument in an aircraft and method of adapting a sidewall

1 . An interior aircraft cabin assembly, comprising:

a sidewall configured to delimit an aircraft cabin and form a visible interior surface of the aircraft cabin, wherein the sidewall comprises a transverse side edge in relation to a longitudinal direction of the aircraft cabin; and

a transition wall forming an extension of the sidewall and configured to bridge a gap between the sidewall and a monument,

wherein the transition wall comprises:

a side fitting forming a transverse side edge of the transition wall, the transverse side edge of the transition wall facing the transverse side edge of the sidewall, the side fitting configured to overlap the sidewall and mate the transverse side edge of the sidewall, and

a mount attached to the transition wall and configured to be mounted to the monument.

2 . The interior aircraft cabin assembly of claim 1 , further comprising:

a sidewall interface configured to be mounted to the transverse side edge of the sidewall.

3 . The interior aircraft cabin assembly of claim 1 , further comprising:

a seal arranged between the transition wall and the monument, or

a bracket mounted to the transition wall and holding the mount, or both.

4 . The interior aircraft cabin assembly of claim 1 , wherein the mount is attached to an exterior surface of the transition wall facing away from an interior space of the aircraft, and wherein the mount is configured to be mounted to an interior surface of the monument facing towards the interior space of the aircraft, or

wherein the mount is attached to an interior surface of the transition wall facing towards the interior space of the aircraft, and wherein the mount is configured to be mounted to an exterior surface of the monument facing away from an interior space of the aircraft.

5 . The interior aircraft cabin assembly of claim 1 , wherein the transition wall widens at a bottom section, or

wherein the transition wall is configured to at least partially replace a window casing of the sidewall, or

both.

6 . An aircraft comprising:

the interior aircraft cabin assembly of claim 1 .

7 . A method for adapting a sidewall of an aircraft to a monument placed adjacent to the sidewall, the method comprising:

preparing a transition wall to bridge a gap between a sidewall and a monument;

providing a side fitting to a transverse side edge of the transition wall in relation to a longitudinal direction of the aircraft facing a transverse side edge of the sidewall, the side fitting being configured to overlap the sidewall and mate the transverse side edge of the sidewall;

attaching a mount to the transition wall;

connecting the side fitting to the transverse side edge of the sidewall, so that the transition wall forms an extension of the sidewall; and

connecting the mount to the monument.

8 . The method of claim 7 , further comprising:

mounting a sidewall interface to the transverse side edge of the sidewall, wherein the sidewall interface has a form mating the side fitting of the transition wall, and,

wherein connecting the side fitting comprises connecting the side fitting to the sidewall interface.

9 . The method of claim 7 , wherein connecting the side fitting comprises connecting in an overlapping and formfitting manner.

10 . The method of claim 7 , wherein preparing the transition wall comprises manufacturing the transition wall to correspond to the gap between the sidewall and the monument in an additive layer manufacturing technique.

11 . The method of claim 7 , further comprising:

cutting the sidewall from a top to a bottom of the sidewall to prepare the gap between the sidewall and the monument.

12 . The method of claim 11 , wherein cutting the sidewall comprises cutting the sidewall along a cutting line running at least partially through a window casing.

13 . The method of claim 12 , further comprising:

determining the cutting line to have maximum portions of equal depth of the sidewall,

wherein a depth of the sidewall corresponds to a level in a direction from an innermost surface of the sidewall to an outermost surface of the sidewall at the window casing.
