Abstract:Rate sensitive foams are often used in aircraft seat designs; recently, the formulation of one of the more common types of foam, Confor™, was changed. The previous Standard version came in four stiffness levels, which all met aircraft flammability requirements. The new version still has four stiffness levels; however,each type will consist of two formulations, one designated Confor™ M and one designated Confor™ AC. The Federal Aviation Administration’s Civil Aerospace Medical Institute (CAMI) conducted testing to determine whether occupant injury risk during vertical impacts would be affected by substitution of the AC material in place of the original material in seat bottom cushions incorporated in dynamically qualified seats. A combination of original Confor™ foams obtained from stock at CAMI and the reformulated aerospace Confor™ supplied by Skandia, Inc., were dynamically tested on a rigid seat. The anthropomorphic test
dummy used was the 50th percentile male FAA Hybrid III. In addition to lumbar loads, occupant kinematics, as well as seat pan loads and floor loads were gathered.
