分析儿童乘员在校车正面碰撞中无安全带约束，使用2点式、3点式和5点式儿童安全带约束条件下的儿童假人的动力学响应和头、胸部的损伤物理参数；分析3点式安全带的两种误用情况下的儿童假人的有关物理损伤参数。结果表明，在正面碰撞事故中，使用5点式儿童安全带更有利于儿童乘员保护；正确使用3点式儿童安全带可以减轻头、胸部损伤风险。

The dynamic response and injury physical parameters of child's head and chest are analyzed in school bus front impact conditions, including no safety belt, 2-point child safety belt, 3-point child safety belt and 5-point child safety belt. Moreover, the injury parameters of child dummy are analyzed in two types of misuse of 3-point safety belts. The results show that in the front impact accidents, the 5-point child safety belt can supply better protection for children, and the injury risk of the head and chest can be reduced by using 3-point safety belt correctly.
