INTERACTION OF THE HYBRID III FEMUR AND PELVIS. A MECHANICAL ANALYSIS

In air bag tests without a restraining seat belt (FMVSS208) several users of the Hybrid III dummy have reported a pelvic interference problem during the tests. An insufficient range of motion and a hard metal to metal contact between the pelvis and the femur has lead to unexpected chest acceleration waveforms. This paper gives a mechanical analysis of this phenomenon, explainig how the forces acting on the dummy lead to a rotation of the pelvis and the chest. Finally two sample tests where the pelvic interference problem has occurred are presented. (A) For the covering abstract of the conference see IRRD 875168.
