Described are lightweight headrests with a perimeter frame 200 with an open central region. The open central region is spanned by a suspension membrane 100 held in tension. The suspension membrane provides support and cushioning functions to a passenger head without the need for internal structures or compression cushions. The perimeter frame of the headrest may have additional cross members spanning the rear portion of the headrest. These cross members may provide additional structure or locate attachment points for the headrest onto the seat.

A modular monocoque backrest is provided. The modular monocoque backrest may comprise a front shroud, a back shroud, and an at least one back spar. The front shroud may be coupled to the back shroud, and the back spar may be configured as a mounting point, enabling the modular monocoque backrest to mount to an aircraft floor. The front shroud and the back shroud may comprise a carbon fiber composite material, allowing the modular monocoque backrest to be modular in nature. The carbon fiber composite material may enable the modular monocoque backrest to have a lightweight design while also maintaining resistance to dynamic crash loads.

A structural element that includes a central part formed of a fibrous material suspended in a thermoplastic matrix and at least one side part formed of a fibrous material suspended in a thermoplastic matrix and having at least one void therein. The central part and the at least one side part are bonded together while in a heated thermoplastic state to form a single, integral structure characterized by the absence of discontinuity across the bond plane of the structure.

A vehicle seat for a passenger, comprising a backrest having a front face directed towards the passenger and a rear face opposite the front face, and a seat part having an upper face directed towards the passenger and a lower face opposite the upper face, wherein the rear face of the backrest and/or the lower face of the seat part comprise(s) at least one area that is deformable in the event of an impact, towards the front face of the backrest and/or towards the upper face of the seat part respectively, and in that the front face and rear face of the backrest, and/or the upper face and lower face of the seat part are located at a distance from each other, at least at said at least one deformable area, so as to define a clearance space, said at least one deformable area of the rear face of the backrest and/or of the lower face of the seat part being configured so as to deform into the clearance space in the event of an impact on the rear face of the backrest and/or the lower face of the seat part, without transmitting the impact to the front face of the backrest and/or the upper face of the seat part respectively.

Components and systems of an aircraft seating assembly are disclosed. The aircraft seating assembly can include a seat pan, a connection frame, and one or more mounts for removably coupling the seat pan to the connection frame. The aircraft seating assembly can include a back support having a removably coupled cushioning member. The aircraft seating assembly can include a tilt system which can allow the back support to articulate relative to the connection frame. The aircraft seating assembly can include a retention system coupled to the back support, the retention system can retain an object in place when in a closed configuration.

A seat system for a passenger aircraft. The seat system includes a passenger seat frame (i) a plurality of spreader bars and (ii) a plurality of laterally extending spar tubes connecting the plurality of spreader bars to one another and at least one canted leg assembly connected to the seat frame for attachment to fixed, spaced apart attachment points on a supporting surface of the passenger aircraft. The canted leg assembly includes: (i) a front leg portion including a front joint clamp for receiving one of the plurality of laterally extending spar tubes in a non-perpendicular attachment point; and (ii) an aft leg portion including an aft joint clamp for receiving another one of the plurality of laterally extending spar tubes in a non-perpendicular attachment point, whereby the seat system is adapted to be laterally positioned and attached to provide different spaced apart passenger seating configurations. A seat back tray table may be attached to the back of the passenger seat frame.

Vehicle seat assemblies including support structures having at least two supports parts coupled at an articulating joint and a pneumatic actuator system including at least one pneumatic chamber inflated and deflated to articulate the articulating joint to move one support part relative to the other or to synchronize movement of two support parts. Support structures can include a backrest coupled to a seat bottom or leg rest coupled to a seat bottom, wherein articulation of the joint causes movement of the backrest or leg rest along a non-hinged trajectory to change a sitting position of the support structure, change seat orientation, and generally improve seat comfort.

A passenger includes at least one seat component including a first material and at least one additive manufactured component including a second material, the at least one additive manufactured component including a plurality of zones. The at least one additive manufactured component is attached to the at least one seat component. The at least one additive manufactured component includes a lattice structure. Each of the plurality of zones have different physical properties.

A central frame assembly for a passenger seat of a vehicle includes a spreader member (201) and a lower frame member (101) comprising at least one clamp member (121) for securing the lower frame member (101) relative to the spreader member (201). The lower frame member (101) may include a vertical portion (102) with a forward lower attachment portion (102.1) and an aft portion (103) with an aft lower attachment portion (103.1). The spreader member (201) and the lower frame member (101) may be aligned such that a centerline of the spreader member (201) and a centerline of the lower frame member (101) are approximately coplanar.

An object of the present invention is to provide a seat unit structure, a seat unit, and an attachment method thereof in which component reinstallation does not arise when the seat unit is attached in an aircraft. One representative seat unit structure according to the present invention relates to a seat unit structure configured to support a seat, wherein the structure has a lower structure having a monocoque structure and defines an outermost shell in at least one direction of the seat unit. That is, the member mounted in the one direction of the seat unit can be stored inside the outermost shell of the structure. In addition, the one direction is the width direction of the airframe.
