The present invention essentially relates to a method for assembling a beam and a structural element of an aircraft seat, characterised in that it comprises: a step of producing at least one recess in an inner face of a beam passage area of the structural element, a step of inserting the beam into the beam passage area, and a step of deforming the beam such that a deformed portion of the beam penetrates into the recess of the beam passage area.

An aircraft seat includes an actuator and a movement transmission device. The movement transmission device includes a frame having at least one bearing face and one braking face; a drive body configured to being rotated relative to the frame, the drive body having a bearing face and a braking face; and an elastic element suitable for keeping the braking face of the drive body at a defined distance from the braking face of the frame, the elastic element having a determined stiffness and being prestressed such that, when an axial load greater than a threshold load is applied to the drive body, the braking face of the drive body comes into contact with the at least one braking face of the frame.

An aircraft seat device has a multi-part backrest frame unit comprising at least one first side frame element, at least one second side frame element, which is arranged on a side of the backrest frame unit that is opposite from the first side frame element, and at least one transverse frame element which is realized separately from the side frame elements and connects the side frame elements, wherein the transverse frame element is realized at least substantially plate-shaped.

Passenger seating positioned proximate to an aircraft interior structure includes at least one seat base assembly and at least one seatback assembly. The at least one seat base assembly includes a seat pan, and is attached to a floor of an aircraft cabin. The at least one seatback assembly includes a support structure and a seatback couplable to the support structure. The seatback includes a surface contoured to a passenger profile. The support structure is couplable to the aircraft interior structure attached to the floor of the aircraft cabin via at least one quick-release mounting assembly, with components of the at least one quick-release mounting assembly being coupled to the support structure and the aircraft interior structure. The at least one seatback assembly is not directly coupled to the at least one seat base assembly.

A passenger seat having a frame is proposed, wherein the frame is intended for securing to a floor of a passenger cabin, wherein the frame comprises a seat divider and beams that run transverse to the seat direction, wherein the seat divider is held by the beams, wherein a housing is disposed on the seat divider, wherein the housing at least partly surrounds a backrest. According to the invention, a structure component is disposed on the seat divider, with an attachment unit for a safety belt for a passenger disposed on the structure component.

Seat assemblies (200) including structural components (212, 222, 232) made of foam are described. A seat sub-assembly (210, 220, 230) can include a frame (214, 224, 234) and a foam support (212, 222, 232). The foam support (212, 222, 232) can be coupled to the frame (214, 224, 234) for receiving a load on the seat sub-assembly (210, 220, 230), dissipating at least half of the load, and dispersing the load through the frame (214, 224, 234).

An aircraft passenger seat including a support framework designed to be fastened to a floor in an aircraft passenger cabin. The support framework has a seat divider and cross rails running transversely to the seating direction, and the support framework is held by the cross rails, a housing including a structural component, and the housing at least partly surrounds a backrest. The structural component is provided on the seat divider, and includes a compound sheet component having one or more cover sheets, with a connecting structure provided between a plurality of cover sheets, more particularly between two cover sheets. The connecting structure creates gaps between the cover plates, and the volume of the gaps makes up at least 50% of the volume between the cover sheets of the compound sheet component.

An aircraft seat may include a backrest and a seat pan coupled to the backrest. The backrest may include a plurality of backrest panels. A set of backrest panels of the plurality of backrest panels may be coupled via a coil hinge. The coil hinge may include a first plurality of holes formed in a first backrest panel of the set of backrest panels. The coil hinge may include a second plurality of holes formed in a second backrest panel of the set of backrest panels. The coil hinge may include a coil spring wound through the first plurality of holes and the second plurality of holes. The first backrest panel and the second backrest panel may be configured to rotate about an axis through the coil hinge when the seat pan and the backrest actuate between a stowed position and a deployed position.

Described are ergonomic passenger seats that may include monocoque or semi-monocoque seat backs, cellular suspension cushions, and tray tables with support arms that may be located within the interior volume of the monocoque or semi-monocoque seat backs when in their stowed positions. The passenger seats offer enhanced passenger comfort and space while providing a lightweight, simple to manufacture design. Monocoque and semi-monocoque seat backs may form integral parts of passenger seats to support additional loads without need for heavy, complex structures. The space within the monocoque or semi-monocoque seat back may then be used for storage or suspension cushions that offer improved comfort with a lighter seat frame. Monocoque and semi-monocoque seat backs may also facilitate the adoption of several other seating mechanisms, such as new seat mounts that allow for improved seat motion that allows for passenger recline with reduced impingement on other passengers' space.

A rotorcraft seating assembly includes a seat base supporting a seat bucket, the seat base having left- and right-side panel portions. Each side panel portion has a linear bucket guide channel set into its inside face (including an upper portion for adjusting the seat bucket relative to the seat base for pilots of varying heights, and a lower portion for energy attenuation (EA) stroking in response to a crash event) and a bucket guide slot set into its outside face (including a linear upper portion corresponding to the range of adjustment of the seat bucket and a curved lower portion allowing the seat bucket to translate forward and away from the seat base during EA stroking). The curved outer bucket guide slot allows for the required EA stroking distance within a minimal vertical space between the seat bucket and the flight deck floor.
