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.

A seat assembly includes a base structure having at least one of a seat pan shell and a backrest shell, and one or more attachment structures configured to removably couple at least one of the seat pan shell and the backrest shell to a seat surface arrangement or a utility surface arrangement. The base structure is convertible between a passenger seat and a utility element based on the coupling of the seat surface arrangement or the utility surface arrangement, respectively, to the base structure.

An interior space for an aircraft includes a cockpit, a cockpit wall separating the cockpit from the remaining interior space, a cabin door arranged directly behind the cockpit wall for accessing the interior space of the aircraft from outside the fuselage, a modular installation space for installation equipment, a plurality of seat rows, a longitudinal aisle extending along the interior space through the seat rows to separate adjacent groups of seats from each other, and an access path for the cabin door. The access path extends from the cabin door to the longitudinal aisle to create an intersection region between the access path and the longitudinal aisle. The modular installation space is arranged directly forward of the seat rows. The access path extends at an angle of at least 100° to the longitudinal aisle in a forward direction.

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 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.

A step assembly installable in a structure such as a housing of an armrest assembly, the step assembly including a base attachable to the structure including a mounting plate having a low profile and a fixed receptacle to be received in the structure, a step plate pivotally attached along a first end to the base along a lower end of the receptacle, the step plate pivotable between a stowed position in which the step plate is housed within the fixed receptacle and a deployed position in which the step plate is outside of the fixed receptacle, the step plate having a first side for supporting a foot, and a release mechanism for releasing the step plate from the stowed position to the deployed position. The step plate deployed for use and concealed from view between uses.

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.

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 step assembly installable in a structure such as a housing of an armrest assembly, the step assembly including a base attachable to the structure including a mounting plate having a low profile and a fixed receptacle to be received in the structure, a step plate pivotally attached along a first end to the base along a lower end of the receptacle, the step plate pivotable between a stowed position in which the step plate is housed within the fixed receptacle and a deployed position in which the step plate is outside of the fixed receptacle, the step plate having a first side for supporting a foot, and a release mechanism for releasing the step plate from the stowed position to the deployed position. The step plate deployed for use and concealed from view between uses.

A ventilated seat assembly with active air circulation including a structural frame element, a cushion assembly supported by the structural frame element, a perforated dress cover, a conduit network embedded in the cushion assembly configured to direct air to at least one target region of the cushion assembly, an air mover coupled in fluid communication with the conduit network, and a controller operable for activating the air mover to cause air to flow through the conduit network to the at least one target region. In operation, the controller activates the air mover to flow air, such as unconditioned air, through the conduit network to be released through the dress cover in the at least one target region.
