| Research Abstract |
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.
