Abstract

Various types of restraining harnesses were worn by anthropomorphic dummy occupants in two 30 m.p.h. barrier crashes of production cars. These tests evaluated the harness systems under the same simulated collision conditions used to determine the dynamic performance of lap-type seat belts. The loads developed in the harness elements were measured and occupant kinematics were studied by analysis of high-speed motion picture film. Restraint applied by the shoulder straps limited upper torso jackknifing, but some of the harness designs did not adequately restrain the lower torsos of the dummy passengers. More complete body restraint was obtained when the lap strap was independent of the shoulder strap. The harnesses imposed restraining loads on the body sufficient to produce structural damage in some of the dummies.
