Since the frontal collisions were dominant forms of the automobile accident, there have been many researches on the occupant behavior. Most of them used the complicated dynamics model of the multiple degrees of freedom and large scale FEM. Therefore, it was difficult to make use of them for the initial design because the specifications of body structures and protection devices were not determined yet. In this paper, a simplified occupant model of the small degrees of freedom was developed, and the spring coefficients of the each body joint and the seat belt were identified by experiments. As a result, a prediction of the chest deceleration, which was one of important performance indexes, and an analysis of dynamics mechanism at the initial design stage became possible.
