A monument is presented. The monument comprises a floor panel; a left face panel perpendicular to the floor panel; a right face panel perpendicular to the floor panel; and an attachment system connecting the floor panel, the left face panel, and the right face panel. The attachment system comprises a right corner bracket fitting connecting the right face panel to the floor panel; a left corner bracket fitting connecting the left face panel to the floor panel; and a filler panel connected to and extending between the right corner bracket fitting and the left corner bracket fitting.

A retractable cargo hook for aircraft is described. The cargo hook comprises a torsion spring allowing rotatable attachment to an aircraft body. An optional recessed portion of the aircraft body can house and receive the cargo hook. This can protect interior components from crashes which can push the cargo hook into the aircraft fuselage, damaging components.

A system for fastening two components is disclosed having a mechanical connection device including two tenons that each extend from an opposite face of an interposed plate, each of the tenons having two appendages forming coupling arms, each appendage being positioned on either side of the tenon. The appendages of one tenon being positioned in a different longitudinal direction than the appendages of the other tenon, each appendage having a coupling component to connect to a device for locking the tenons and two end fittings that each have a slot in which each of the tenons of the connection device is able to be fitted, each appendage protruding out of the slot on either side thereof.

A plinth attachment system for attachment to at least one track includes: a first plate having a first side configured for mounting to a longitudinally extending track, and a first mounting feature for mounting a first structure; and a second plate having a first side configured for mounting to the track, and a second mounting feature for mounting a second structure. When mounted on the track, at least one interlinking feature of the first side of the first plate and at least one interlinking feature of the first side of the second plate interlock at the track, and, the first mounting feature and second mounting feature are aligned at essentially equivalent longitudinal positions.

A trolley lift for connecting a lower aircraft deck to an upper aircraft deck. The trolley lift comprises a platform configured to accommodate at least one trolley, wherein the platform delimits a lift compartment at the bottom, and a cover which delimits the lift compartment at the top. In particular, on a side facing away from the lift compartment, the cover at least partly forms a floor of the upper aircraft deck. Furthermore, an aircraft area having a trolley lift and an aircraft having a trolley lift and/or an aircraft area are described.

A pressure deck assembly for a fuselage includes a longitudinal beam extending a length along a roll axis of the fuselage. The longitudinal beam includes a central member and opposing first and second flanges extending from the central member. The first flange includes a first upper side and a first lower side. The second flange includes a second upper side and a second lower side. The pressure deck assembly includes a pressure deck that includes first and second deck segments. The first deck segment is joined to the first flange of the longitudinal beam along the first lower side of the first flange. The second deck segment is joined to the second flange of the longitudinal beam along the second lower side of the second flange.

There is provided an air grille panel assembly for a vehicle. The assembly includes an air grille panel having air grille openings, a top end, and a bottom end. The top end is configured for coupling to a sidewall panel in a cabin of the vehicle. The bottom end is configured for coupling to a raceway assembly on a floor in the cabin. The assembly further includes a frame member disposed around a perimeter of each of the air grille openings, to define each of the air grille openings, an air grille coupled to the frame member and covering each of the air grille openings, and a cover member releasably attached to the air grille. The assembly is configured for coupling to the sidewall panel, via a float attachment, that allows for a vertical adjustment, to accommodate different installed positions of the assembly in the cabin of the vehicle.
