Abstract：The protection effeciency on the injury risk of child occupant was evaluated when the side airbag deployed for side impact. Based on the Prescribed Structure Motion, LS-Dyna and MADYMO softwares were used to establish the simulation models. Simulations with and without deployed side airbag were carried out under Euro-NCAP side impact. The dynamic response parameters of head, neck and thorax of six-year-old child with misusing and correct using booster seat were analyzed and compared. The results indicate that the child with misusing booster seat may not receive injury risk from deployed side airbag for head and thorax. The child with correct using booster seat may receive the protective benefit from deployed 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 situation.
