摘要
在第I质量组中,P3假人的约束方式为五点式约束即CRS自身安全带约束;在第II质量组中,P3假人的约束方式是三点式约束即成人安全带约束。基于以上规定,文章以强制性3C认证试验结果为依据,在其他试验条件都相近的情况下,通过两种约束方式下的试验数据的比对可知,三点式约束系统能够更加有效地减小儿童乘员的头部位移,五点式约束可以有效地减小儿童乘员的胸部加速度,结合儿童乘员损伤机理,在交通事故中应更加注重对儿童乘员头部的保护,因此本文认为对于2~4岁左右的儿童乘员,应尽量使用成人安全带约束。
In the I quality group, the constraint mode of P3 dummy is five point constraint, that is, CRS self seat belt constraint. In the II quality group, the constraint mode of the P3 dummy is the three point constraint, the adult seat belt constraint. Based on the above regulations, based on the results of compulsory 3C certification test, the three point constraint system can reduce the head displacement of children more effectively, and the five point constraint can reduce the child＇s chest acceleration effectively. Combined with the mechanism of children＇s occupant damage, it is necessary to pay more attention to the protection of children＇s head in traffic accidents. Therefore, it is believed that the adult safety belt should be used as far as possible for the children at the age of 2~4.
