The invention discloses an anti-diving energy absorption structure of the automobile seat and an automobile seat. The anti-diving energy absorption structure comprises a seat cushion half basin, a front cross beam and energy absorption connecting pieces, one end of each energy absorption connecting piece is connected with the seat cushion half basin, the other end of each energy absorption connecting piece is connected with the front cross beam, and the multiple energy absorption connecting pieces are of an integrated structure. Each energy absorption connecting piece comprises a plurality ofbending parts, the bending directions of every two adjacent bending parts are opposite, and the bending parts are arranged in the gap between the seat cushion half basin and the front cross beam; whenthe energy absorption connecting piece is stressed, the multiple bending parts move along with the seat cushion half basin with the front cross beam as a support to generate energy-absorbing plasticdeformation, and under the condition that certain rigidity and strength are guaranteed, the phenomenon that passengers slide forwards by a large margin due to the inertia effect to dive in the head-oncollision process of the automobile is avoided, injuries to the passengers are reduced, and the collision safety is improved.
本发明公开了一种汽车座椅的防下潜吸能结构及汽车座椅,包括座垫半盆、前横梁和吸能连接件,吸能连接件的一端与座垫半盆连接,吸能连接件的另一端与前横梁连接,吸能连接件为若干个,吸能连接件为一体式结构,吸能连接件包括若干个弯曲部,相邻的两个弯曲部的弯曲方向相反,弯曲部设于座垫半盆与前横梁之间的空隙处,受力时,若干弯曲部以前横梁为支撑,伴随座垫半盆一起移动进而产生吸能塑性变形,在保证一定的刚度强度下,避免汽车在发生正面碰撞过程中乘员由于惯性作用大幅向前滑动所造成的下潜现象,降低乘员伤害,提高碰撞安全性。
