根据近似程度，将正面碰撞试验中车体B柱（x向）加速度波形分成前低后高、前高后低2种阶梯形类型，研究了2种波形在假人相对车体运动中的表现及对假人胸部造成的伤害，并推导出理想B柱加速度波形。对3种波形下安全带的选配进行研究，指出在安全带选配时，应从腰带能够平衡假人相对运动、肩带能够调节假人运动姿态角度出发进行考虑，并具体指出了各波形下安全带的选配方向。

In this paper, based on the degree of approximation, we divide the vehicle B-pillar acceleration waves (x direction) in the frontal impact test into two kind of ladder waves, one is that the front is high and the back is low, the other is that the front is low and the back is high. The state of the dummy moving relative to vehicle motion and the dummy' chest injury in two ladder waves are studied, and the ideal B-pillar acceleration wave curve is derived. Through the research on the selection of seat belt in three kinds of wave, it is indicated that, when selecting the seat belt, it should take into consideration that the waist belt can balance the dummy relative movement and the shoulder belt can adjust the dummy's motion posture, the guidance on selection of the seat belt for each kind of waves is also indicated in the paper.
