A passenger seat assembly includes a riser attached to an upper surface of a floor of the vehicle, a seat attached to an upper surface of the riser, and at least one shell portion attached to the upper surface of the riser. The riser includes at least one door for accessing an interior volume of the riser. At least a portion of the interior volume of the riser is a luggage storage volume.

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.

A passenger seat system for a cabin of a means of transportation includes: a passenger seat having a seat frame having a holding section and a plurality of supporting elements for coupling to a floor; and, a slide device spaced apart from the holding section and having a base and a retaining device, to be detachably fastened to the base and be coupled to a supporting element. The base has a contact surface for laying onto a cabin seat rail, a locking device for locking the base on the seat rail, and a holding device for releasably holding the retaining device. The slide device is designed to lock the retaining device on the holding device selectively in a first or a second position or to release the retaining device and, when the retaining device is released, to permit motion of the retaining device between the first and the second positions.

A passenger seat includes a seat frame, a plurality of legs extending down from the seat frame where each of the plurality of legs includes an upper end attached to the seat frame and a lower end, and at least one tube attached to the lower end of at least one of the plurality of legs. The at least one tube includes at least two attachments to a floor structure. The at least one tube includes at least one bent portion.

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.

Example methods and systems for isolating and alleviating load in an aircraft are described, comprising providing a sliding joint between a seat track and a flight deck floor panel. The sliding joint comprises a lug comprising a first end and a second end opposite the first end, wherein the first end is adapted to attach to the seat track and the second end comprises an elongate aperture, and a clevis comprising an oblate shaped slider bushing that is coupled to the lug.

An armrest assembly for a passenger seat may include an armrest and an attendant step assembly. The armrest may include a top side and a bottom side, and the attendant step assembly may be connected to the bottom of the armrest. The attendant step assembly is movable between a stowed position and a deployed position relative to the bottom side of the armrest.

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.

An aircraft that includes a fuselage having a floor, first and second outboard walls and an aisle, and a first seat and storage system that is positioned between the first outboard wall and the aisle. The first seat and storage system includes a seat that includes a seat back and a seat portion, and a storage assembly that includes a storage portion and an extension portion. The storage portion defines a storage interior and a storage opening and includes a cover that is movable between an open position and a closed position. The storage opening faces the aisle. The extension portion extends from the storage portion toward the first outboard wall. The storage assembly defines a top surface to which the seat is secured. The storage assembly defines an under seat cavity below a bottom surface of the extension portion.
