Abstract

Chest deflection and acceleration of crash dummy have been used as chest injury measures in frontal crash test. In this research, mechanism and relation of the two chest injury measures were investigated. The seat belt path and force limiter load were changed to clarify the effects on the chest injury by Hybrid III dummy and human finite element models. The chest acceleration was derived from external and internal joint force and the effect of seatbelt path was small, whereas the chest deflection was affected by the seatbelt force and the seatbelt path.
