Patent attributes
Described are ergonomic passenger seats that may include monocoque or semi-monocoque seat backs, cellular suspension cushions, and tray tables with support arms that may be located within the interior volume of the monocoque or semi-monocoque seat backs when in their stowed positions. The passenger seats offer enhanced passenger comfort and space while providing a lightweight, simple to manufacture design. Monocoque and semi-monocoque seat backs may form integral parts of passenger seats to support additional loads without need for heavy, complex structures. The space within the monocoque or semi-monocoque seat back may then be used for storage or suspension cushions that offer improved comfort with a lighter seat frame. Monocoque and semi-monocoque seat backs may also facilitate the adoption of several other seating mechanisms, such as new seat mounts that allow for improved seat motion that allows for passenger recline with reduced impingement on other passengers' space.
