A seat indexing system and method for an internal cabin of a vehicle include a seat assembly, and an indexing wheel coupled to the seat assembly. The indexing wheel is configured to be moved between a stowed position, in which the indexing wheel is disengaged from a seat track, and a deployed position, in which the indexing wheel engages the seat track.

An aircraft seat may include an upper aircraft seat assembly, a lower aircraft seat assembly, and a frame actuation assembly configured to actuate the upper aircraft seat assembly relative to the lower aircraft seat assembly. The lower aircraft seat assembly may include at least one spring coupled to a foundation with a sloped actuation surface configured to cause the upper aircraft seat assembly to be at a decreased height when in a bed position. The compressing of the at least one spring may be configured to counterbalance a load within the aircraft seat and generate a controlled actuation of the upper aircraft seat assembly from an upright position to the bed position. A return force provided by the at least one spring may assist the frame actuation assembly during actuation of the upper aircraft seat assembly from the decreased height of the bed position to the upright position.

The invention provides a rear side shell structure in the form of a back covering that can be attached to a lower structure of a seat without support legs. One representative rear side shell structure and seat unit according to the invention relates to a rear side shell structure for covering a back of a seat, the rear side shell structure including a front surface member and a rear surface member, wherein a reinforcing region in which a space reinforcing member is provided between the front surface member and the rear surface member is provided in a portion of the rear side shell structure, and the front surface member and the rear surface member are directly joined to each other except for in the reinforcement region. Further, the front surface member and the rear surface member are formed of composite members. Also, the space reinforcing member has a honeycomb structure.

A seat leg assembly for a passenger seat includes a brace member to extend from a front end of a base frame of the passenger seat to a rear floor fitting; a front leg to extend from a front floor fitting to the brace member and connected to the brace member; a rear leg portion extending from a rear end of the base frame to the brace member; and a first joint structure connecting the rear leg portion to the brace member.

A frame beam member may include a tubular volume. The tubular volume may include at least one wall with one or more undulations in a radial direction along a length of the tubular volume. The one or more undulations may be configured to allow the tubular volume to absorb energy of a load applied during a flight scenario through local bending of the one or more undulations. The one or more undulations may be configured to have a first curvature when unloaded, and may be configured to have a second curvature when the load is applied. The second curvature may be different than the first curvature. The frame beam member may be one of a plurality of frame beam members of the aircraft seat frame. The plurality of frame beam members may be configured to couple to a plurality of joints of the aircraft seat frame.

The present disclosure provides a swivel stop comprising a rotating member, a first boss coupled to the rotating member and a second boss coupled to the rotating member, and a second plate having a first interference surface and a second interference surface. An interference between the first boss and the first interference surface and the second boss and the second interference surface tends to limit the rotation of the rotating member with respect to the second plate. The swivel stop may further comprise a rail wherein the second plate is configured to translate along the rail.

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 vehicle seat comprising a stand and a bucket having a seat pan and a seat back. Said stand serves to fasten said bucket to a floor of said vehicle and to absorb deformation of said floor while limiting the mechanical stresses that are transmitted to said bucket. Said pan is connected to said bucket via a revolute joint for pivoting about a transverse direction and by energy absorber devices. The stand has two first legs forming a fork and connecting the front of said bucket to said floor via ball joint connections. The bucket is connected to said floor at the rear of the seat via two ball joint connections. The stand is thus connected to said bucket via three points and to said floor via four points making it possible to avoid twisting said bucket as a result of deformation of said floor.

The present invention proposes an air passenger seat comprising a frame that is designed to be fastened to a floor in an air passenger cabin, the frame comprising a seat divider and rails running transversely to the seat direction, wherein: the seat divider is held in place by the rails and is disposed behind a first front rail, which is positioned in front, with regard to the seat direction of the rail; and wherein perpendicular to a plane, which is formed by points for fastening the frame to the floor of an air passenger cabin, is a height difference between the rails so that the rear rail is positioned above the front rail at least by a difference d of 20 mm.

A fuselage is described that includes a plurality of frames and a plurality of seat rows spaced apart according to a seat pitch. Each frame includes a lateral floor beam, and each seat row of the plurality of seat rows includes a load-bearing structural base with a plurality of legs attached to a proximal lateral floor beam and a distal lateral floor beam. Each seat row also includes a seat or bank of seats attached to the load-bearing structural base, where the seat or bank of seats includes at least one seat bottom and at least one seat back. Further, each seat row includes an interface between (i) the load-bearing structural base and (ii) the seat or bank of seats to allow for attachment and detachment of the seat or bank of seats relative to the load-bearing structural base.
