The aim of this paper is to evaluate the injury risk of child occupant exposed to the deployed side airbag in side impact. Based on the Prescribed Structure Motion, LS-Dyna and MADYMO softwares was used to develop the simulation models. Simulations with and without side airbag deployment were carried out under the Euro-NCAP side impact conditions. The dynamic response parameters of head, neck and thorax of 6-year-old child with misusing and using correctly booster seat were analyzed and compared. The results indicated that the child misusing booster seat may not receive the threat of side airbag for head and thorax. The child using booster seat correctly may receive the protective benefits of side airbag for head and thorax. Whether a child misuses or uses correctly booster seat, the injury risk of neck depends on the real impact situations.
