摘　　要：本文根据人体动态响应特性提出座垫应在弹射开始后10ms 以内压缩至最薄,以避免增加人体超调。相应地要求在坐人后坐骨结节处的座垫厚度不要超过15mm。由于人体工程学研究的动态指标与描述座垫材料的参数不同,使得模型研究与材料之间没有直接联系,因此在采用新材料制作座垫时需要用人体冲击试验进行动态检验。Seat cushions are used to provied sitting comfort,however the potentialof vertebral fracture may be increased during ejection.Acoording to dynamicresponse of human body,it is required that the cushion must be compressedto the bottom within 10ms after igniting ejection and that the thickness ofthe cushion beneath the occupantt'S ischial tuberosities must not be greaterthan 15mm for preventing dynamic overshoot.Since the parameters of seatcushions are differ from dynamic indices of human engineering,their is nodirect connection between the model research and materials.Human impacttest is nessary for dynamic evaluation when the cushion is made of anew kind of material.
