The performance of rear facing child restraints in frontal crashes can be determined by controlling a) the child's kinematics and b) interactions with vehicle structures. Twelve sled tests were performed to analyze the effect of the location and structural properties of vehicle interior components. The role of restraint kinematics was studied by developing computational models which underwent idealized motions. Stiff structures originally offset from the restraint, but which contact the restraint late in the test, cause increased injury values. Attachment methods which reduce child restraint rotation and more rigidly couple the restraint to the vehicle result in the best safety performance.
后向儿童安全座椅在正面碰撞中的性能可通过控制以下两点来确定
a）儿童的运动学；b）与车辆结构的相互作用。进行了12次雪橇试验，以分析车辆内部部件的位置和结构特性的影响。通过开发经历理想化运动的计算模型来研究安全座椅运动学的作用。原本与安全座椅偏移但在试验后期与安全座椅接触的刚性结构会导致伤害值增加。减少儿童安全座椅旋转并将安全座椅更牢固地与车辆连接的连接方法可实现最佳安全性能。
