摘　　要：在C-NCAP的3项碰撞试验中,后排乘员在100%正面碰撞和40%偏置碰撞中失分较多,颈部和胸部为主要失分点。为提高后排乘员得分,分析了正面碰撞中后排乘员颈部和胸部受力情况和伤害机理,提出后排增加限力式安全带、预紧限力式安全带、膝部气囊及头部气囊4种优化方案,并利用Madymo仿真软件进行分析。结果显示,头部气囊和预紧限力式安全带对后排乘员起到了很好的保护作用,其他优化方案改善效果较小。综合各种技术因素,提高后排乘员保护性能的最有效方法为增加预紧限力式安全带。This paper inlrnduees Ihe ability to hear file load and injury fia＇ rear seat passenger＇s neck and chest in fi＇ontal impact＋ des〈＇ribes 4 design optimization methods such as installing force limiler seat belt, prelensioner safety belt, knee air bag and head air hag due to lhe aim of increasing the score of real seat passenger.
