According to the cushion applied to the child safety seat, the child safety seat and the method for reducing the injury risk of the child passenger, the cushion is laid on the child safety seat, the through hole is formed in the middle of the cushion so that the front straddle belt can penetrate through the through hole for constraint connection, and the seat part is divided into the hip supporting area and the thigh supporting area with the through hole as a reference; at least the thigh supporting area is filled with an energy absorption material with a slow rebound characteristic; under the condition that a vehicle collides or drastically slows down, the action time of elastic compression deformation of a child passenger on the thigh supporting area is effectively prolonged, the thigh supporting area reduces the resultant acceleration and displacement of corresponding parts of the body of the child passenger through counter-acting force, and the real energy absorption effect is achieved; therefore, the injury index of the child passenger is optimized, the injury risk of the child passenger is reduced, and the riding safety, reliability and comfort of the child passenger are improved.
本发明一种应用于儿童安全座椅的坐垫、儿童安全座椅及降低儿童乘员伤害风险的方法,坐垫铺设于儿童安全座椅上,通过在坐垫中部设置通孔以供前跨带穿过约束连接,并以通孔作为参考将座部分为臀部支撑区域和大腿支撑区域,且至少在大腿支撑区域填充有具有慢回弹特性的吸能材料;在车辆发生碰撞或急剧减速情况下,有效地延长了儿童乘员对大腿支撑区域的弹性压缩形变的作用时间,大腿支撑区域通过反作用力降低儿童乘员身体相应部位的合成加速度及位移,实现真正吸能效果,确保儿童乘员的伤害指标达到最优化,降低了儿童乘员的伤害风险,提高了儿童乘员的乘坐的安全性、可靠性和儿童乘员乘坐的舒适性。
