The utility model discloses a cushion supporting spring structure and an automobile seat cushion. The cushion supporting spring structure comprises a plurality of spring steel wires mounted in a cushion framework. Each spring steel wire is provided with a plurality of bends, the bending density of each spring steel wire at the position corresponding to the lower portion of the buttocks of a humanbody is maximum, and the bending density is gradually reduced in the direction away from the position. The spring steel wires are installed side by side in the left-right direction of the cushion, andthe diameter of the spring steel wire in the middle and the elasticity modulus of materials are smaller than those of the spring steel wires on the left-right outer side. In the structure, the totallength of the spring steel wires is increased in a bending mode, so that the overall rigidity coefficient is reduced, and the deformation is increased. The more the bending times are, the higher the density is, the longer the deformable lengths of the steel wires is, and the smaller the rigidity coefficient is; on the contrary, the smaller the bending frequency is, the smaller the density is, thesmaller the deformable length of the steel wires is, and the larger the rigidity coefficient is. Through the above arrangement, the rigidity coefficient change consistent with the human body load distribution rule is realized, and the static and dynamic comfort of the seat is improved.

    一种坐垫支撑簧结构及汽车座椅坐垫,包括安装在坐垫骨架中的若干根弹簧钢丝。所述弹簧钢丝具有多道弯折,所述弹簧钢丝在对应人体臀部下方位置的弯折密度最大,并向远离该位置的方向弯折密度逐渐减小。若干根所述弹簧钢丝按照坐垫的左右方向并排安装,位于中间的弹簧钢丝的直径和材料的弹性模量小于位于左右外侧的弹簧钢丝。本结构中,弹簧钢丝通过折弯方式来增加钢丝的总长度,以减小整体刚度系数和增大变形量。折弯次数越多即密度越大,钢丝可变形长度越长,刚度系数越小;反之折弯的次数越少即密度越小,钢丝可变形长度越小,刚度系数越大。通过这样设置,实现与人体载荷分布规律一致的刚度系数变化,提升座椅的静态和动态舒适性。
