In order to study the influence of the child restraint system's (CRS) design parameters on the child occupant injury, a frontal crash simulation model with an ISOFIX CRS was established under ECE R129 regulation, and the simulation results were verified with sled test. The influences of the friction coefficient between children's safety belt and child dummy, the stiffness of children's safety belt, the location of shoulder strap of children's safety belt and the friction between child seat and car seat on injury parameters, such as head injury criterion (HIC15) values and chest resultant acceleration, were analyzed by using orthogonal experimental design. The hole position of seat belt shoulder strap has greatest effect on the WIC value and head displacement in X direction, it makes WIC value reduced by 7.2% compared with the original scheme, and the head displacement reduced by 1.4%. © 2016 IEEE.
