The purpose of this study is to evaluate the protective capability of the children's helmet to various head shapes by using the FE model of the children's helmet and 1-3-years old child's representative head shapes. Head FE models of various shapes in each age were constructed based on the distribution of head width, head length and head height in Japanese children from one to three years old. Helmet FE model was constructed based on the shape data of existing children's helmet. The analysis simulating a fall from a bicycle was done by using these models. The analytical results showed that the protective capability of a helmet was affected by matching the size to be able to wear the helmet deeply to avoid a force concentration at the contact area of the head.
