Child occupant protection in vehicle side impacts

事故数据显示，儿童经常因接触车辆侧面内部而受伤。采用有限元分析方法进行了斜侧面碰撞仿真，儿童头部与侧门槛接触，导致头部损伤标准（HIC）较高。当在儿童约束系统（CRS）的肩带中增加松弛时，这种头部接触更加严重。结果表明，CRS使用不当可能是导致颅脑损伤的原因之一。进行了车对车碰撞试验，证明儿童假人的头部与侧玻璃和门槛接触，具有高HIC值。

The accident data shows that children were injured frequently from making contact with vehicle side interior. Oblique side impact simulation were conducted using finite element analysis, and the child head made contact with the side doorsill, which led to high head injury criterion (HIC). This head contact was more severe when the slack was added in the shoulder harness of child restraint system (CRS). It was indicated that the CRS misuse can be one of the causes of head injuries. The car-to-car crash test was carried out, and it was demonstrated that the head of the child dummy made contact with the side glass and door sill with high HIC value.
