Seat systems are required to pass a fatigue test consisting of a varying load applied to the seat back for a large number of cycles. This test is derived from a seat occupant study documented in SAE paper 840509, Passenger Car Seating Loads; A Human Factors Engineering Problem. The test takes an average of two weeks to complete for a given program. The purpose of the study presented here is to develop an equivalent fatigue test that shortens the required testing time and provides the same results and confidence. For the covering abstract of the conference see IRRD 875189.
