ABSTRACT:
Improved, lightweight multi-passenger aircraft seating unit utilizes an elongated, generally S-shaped, composite panel to provide the sole support for the seat cushions, the seat back and seat back tray table, the seat belt anchors and the armrests. Front legs and rear legs made of thin sheet metal can be attached directly to the panel by bolts passing through the panel. A downwardly projecting front portion of the panel and an upwardly projecting rear portion, in cooperation with channel-shaped members bonded to the panel's peripheral edges, enhance the rigidity of the panel. The unit provides cantilever support without the necessity for the front and rear tubular stretcher members and the fore and aft support members used in conventional seats. The composite panel has a honeycomb core and its top and bottom skin surfaces are formed of continuous layers of resin-impregnated fibrous material such as graphite fibers, with additional swatches of such material overlying and integrally bonded into the skin. The additional reinforcement material is laminated into regions of additional stress such as those where the legs, back, seat belt anchors and armrests are to be attached. The seat back is doubly curved to provide lumbar and shoulder support and good comfort with a thin constant thickness rear pad. The seat allows spacing between seat rows to be determined virtually solely by the dimensions of the occupants.
