A separable multiple-piece frame assembly (100) for a passenger seat of a vehicle includes a first spreader portion (101) with an inner face, a second spreader portion (201) with an inner face, a plurality of attachments (11, 12, 13, 14, 15, 16) for releasably attaching the first spreader portion (101) and the second spreader portion (201), and an attached configuration. In the attached configuration, the inner face of the first spreader portion and the inner face of the second spreader portion are in contact with one another.

There is provided a system comprising a plurality of movable seats arranged in a seating area, a detection device, a non-transitory memory storing an executable code, a hardware processor executing the executable code to receive a first input from the detection device indicating an individual is present in the seating area, determine a first position of the individual in the seating area at a first time based on the first input, and arrange the plurality of seats in a first configuration based on the first position of the individual, wherein arranging the plurality of seats includes moving at least one of the plurality of seats to a new position.

A seat configuration verification system and method for an internal cabin of a vehicle include a verification control unit that receives position data regarding positions of seat assemblies within the internal cabin. The verification control unit compares the position data with seat configuration data representative of the seat configuration to determine if the positions of the seat assemblies within the internal cabin conform to the seat configuration.

The invention provides a kit of parts for assembling an aircraft seat unit, comprising a frame with a slot, a panel for forming a shell of the aircraft seat unit and defining a footprint of the aircraft seat unit, having a first end and a second opposite end, the first end configured to be slid in and out of the frame slot to provide a variable dimension from the frame to second opposite end of the panel, and a fixing mechanism for fixing the panel within the frame slot, in a configuration providing a desired value of aircraft seat unit variable dimension. The invention also provides a plurality of such kits of parts, an aircraft seat unit and an aircraft cabin comprising a plurality of such aircraft seat units or made from such kit of parts, and methods of installing an aircraft seat unit.

In one embodiment, an apparatus may comprise: a floor panel for a rotorcraft; one or more puck fasteners in the floor panel, wherein each puck fastener comprises an attachment fitting and a plurality of internal flanges, wherein the plurality of internal flanges within each puck fastener are adjacent; and one or more seating fixtures coupled to the floor panel using the one or more puck fasteners.

A plinth attachment system for attachment to at least one track includes: a first plate having a first side configured for mounting to a longitudinally extending track, and a first mounting feature for mounting a first structure; and a second plate having a first side configured for mounting to the track, and a second mounting feature for mounting a second structure. When mounted on the track, at least one interlinking feature of the first side of the first plate and at least one interlinking feature of the first side of the second plate interlock at the track, and, the first mounting feature and second mounting feature are aligned at essentially equivalent longitudinal positions.

An aircraft seat set is provided that allows for providing extra room for passengers and/or allow for selectively increasing the width of an aircraft aisle during enplaning and deplaning and/or increasing the width of some seats during flight. In one embodiment, the aisle seat of the seat set is movably connected to the seat frame of the seat set to allow the aisle seat to be disposed above and in front of the middle seat of the seat set for enplaning and deplaning.

For a seat group arrangement for a passenger cabin of an aircraft it is proposed to realize a temporary enlargement of the circulation area by widening the longitudinal aisle of the aircraft for the entry and exit period. For this purpose, a passenger seat group has a supporting frame which is provided with seat legs for fastening to the aircraft floor. At least one first fixedly secured seat having in each case a seat part and in each case a backrest and a further seat which is movable in the transverse direction and has a seat part and a backrest is provided on the supporting frame. The further seat is connected to the supporting frame via a folding device, and the folding device is configured to realize a change in width of the further seat in relation to the seat legs of the supporting frame.

A aircraft passenger seating arrangement comprises a seat (1), a secondary surface (4) spaced to one side of the seat (1), in a direction substantially parallel to the width of the seat; and an infill surface (3) deployable into a space between the seat (1) and the secondary surface (4) so as to form a substantially continuous sleeping surface along the secondary surface (4), the infill surface (3) and the width of the seat (1).

There is provided a seat base frame (10) comprising one or more base frame tubes (16) having noncircular cross-sections. In a specific example, the tubes (16) have elliptical cross-sections. Further embodiments provide base frame tubes (16) made of magnesium or magnesium alloys.
