Abstract

In air bag tests without a restraining seat belt (FMVSS 208) 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)
