Abstract:

Child restraint system(CRS)is a new study field in the world. Especially in China, the CRS research is particularly meaningful with the rapid growth of the number of child passengers. The amendment and optimization on the regulations of CRS are brought out based on the distinction between CRS and occupant safety systems. The application of advanced design theory, the technology of computer simulation and the systematical analysis strategy will bring a new prospect for the development of CRS.
