Abstract
A series of 22 dynamic tests was conducted on general aviation occupant restraint systems. These tests utilized lap belt, and lap belt/shoulder harness restraint systems. With the exception of general aviation aircraft type certificated after September 1969, the Federal Aviation Regulations require only lap belt restraint systems for emergency landing conditions. Based on the longitudinal deceleration/time response of anthropomorphic dummy occupants, it was demonstrated that the lap belt/shoulder harness restraint systems offered occupants successful restraint at occupant inertia force levels substantially above the current regulatory level. The tests, preliminary in nature, warranted continuation of the test program, in that the lap belt/shoulder harness restraint systems showed promise for regulatory inclusion, by virtue of the fact that results were achieved with restraint systems offered as options in recent years, requiring minimal weight increase with fuselage reinforcement adaptable to retrofit as well as new assembly.
