Vertical take-off and landing (VTOL) aircraft can provide opportunities to incorporate aerial transportation into transportation networks for cities and metropolitan areas. However, VTOL aircraft can be sensitive to uneven weight distributions, e.g., the payload of an aircraft is primarily loaded in the front, back, left, or right. When the aircraft is loaded unevenly, the center of mass of the aircraft may shift substantially enough to negatively impact performance of the aircraft. Thus, in turn, there is an opportunity that the VTOL may be loaded unevenly if seating, luggage placement, and/or positions of internal components are not coordinated. Among other advantages, dynamically assigning the payloads and adjusting components of the VTOL aircraft can increase VTOL safety by ensuring the VTOL aircraft is loaded evenly and meets all weight requirements; can increase transportation efficiency by increasing rider throughput; and can increase the availability of the VTOL services to all potential riders.

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.

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.

A rack is made from a plurality of laminated layers. Each layer defines an alignment feature that allows all of the layers to be affixed to a base plate of an aircraft seat assembly and align the teeth of the rack to within five ten-thousandths of an inch. The rack includes a straight portion and a curved portion such that a pinion gear on the aircraft seat assembly can move the aircraft seat assembly along tracks with straight and curved portions.

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.

A structural shroud for a passenger seat assembly includes a hollow body having a first end, a second end opposite from the first end, and a central cavity between the first end and the second end. In certain embodiments, the structural shroud may include a magnesium alloy and/or an aluminum alloy, and may be formed via casting, forging, and/or additive manufacturing, among others. In some embodiments, a base frame assembly for a passenger seat assembly includes a monolithic base frame having a first leg portion and a first tube portion integrally formed with the first leg portion.

A leg assembly for a passenger seat for a vehicle such as an aircraft includes a forward leg and an aft leg. The forward leg includes a top end and a bottom end opposite the top end, and the top end of the forward leg includes a forward aperture for receiving a first base frame tube of the passenger seat. The aft leg includes a top end, a bottom end, a forward side, and an aft side, and the top end of the aft leg includes an aft aperture for receiving a second base frame tube of the passenger seat. The forward side at the aft aperture of the aft leg may be a forward-most portion of the aft leg, and the aft leg is indirectly connected to the forward leg.

A method of upholstering a seat having a seating frame, and a corresponding attachment assembly, comprises providing a diaphragm generally having a weave of warp and weft yarns with an attachment member for installation of the diaphragm to the seat. The attachment member comprises an adapter strip and a coil member. The coil member is adapted to be intertwined with the weave of the diaphragm and thereafter inserted into and held by the channel in the seating frame. The adapter strip may be connected to the coil member to facilitate feeding the assembly through the channel in the seating frame. Alternately, the adapter strip can replace the channel in the seating frame and instead provide a mounting structure to which the diaphragm can be attached through the coil member's engagement with the adapter strip. A retainer sheet may also be used to maintain a desired tension of the diaphragm during installation.

A seat unit and a lower structure thereof that are not restricted in their positional relationship with seat tracks provided in advance in the airframe. One representative seat unit of the present invention and the lower structure thereof includes a hollow structure integrally formed using a composite member. The hollow structure is hollow in a front direction of the seat unit. The hollow structure has a quadrilateral shape in the front direction of the seat unit. In addition, a partition plate is disposed in the hollow structure. Furthermore, the lower structure includes attachment points to an aircraft at three locations on its bottom. In addition, a block is embedded in the composite member at the attachment point, and a thickness of the composite member around a bracket coupled to the block is less than thickness at other locations.

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.
