儿童乘员约束系统也称儿童安全座椅，是一项新兴的研究领域。随着儿童乘员数量的上升，对于能够有效地保护儿童乘员安全的约束系统的研究具有特殊的重要意义。介绍了儿童乘员约束系统与成人乘员约束系统在分类和组成上的区别，以及相应的发展和健全的安全法规；展望了先进的设计理论、计算机仿真技术应用和系统型研究策略给儿童乘员约束系统研究开辟的前景。

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.
