Abstract: There is provided an air duct assembly. The air duct assembly has a deformable duct preform having securing portions formed along opposing longitudinal edges. Each securing portion has a flange portion and a radius portion. The air duct assembly further has a panel structure having a pair of longitudinal base members mounted thereon in an opposed, spaced, predetermined relationship. Each longitudinal base member has a retaining element along a longitudinal edge of the longitudinal base member. Each retaining element is pre-configured to engage the flange portion and the radius portion of each securing portion to attach the deformable duct preform to the longitudinal base members and to form an air-leak resistant seal. The deformable duct preform is adaptable in a cross-sectional profile in relation to variations in attachment of the deformable duct preform to the longitudinal base members.

Abstract: An interior lining interface incorporates a decorative interface ring having a substantially flat flange with multiple bearing ring bosses on an inner surface of the flange for engagement of an inner surface of a rim of a window ring. Multiple friction fit legs extend from the flange and are received within and constrained by the interface ring to the widow ring rim. A window reveal has a mating surface contacting the flange.

Abstract: A crew rest berth support system includes a crew berth assembly having first and second berths. Hook assemblies suspend the first berth from mobile platform structure. Pin assemblies suspend the second berth from the structure. Cam assemblies connect the first and second berths. The hook assemblies permit first berth rotation in a first path and the pin assemblies permit second berth rotation in a second path substantially perpendicular to the first path. When the first and second berths are connected using the cam assemblies the crew berth assembly is restrained from motion in either the first or the second paths. An entrance cap rotatably mounted to the platform structure prior to the first and second berths is also provided.
