The invention discloses a stretching type rear-end collision seat energy absorption structure, which comprises a seat cushion side plate and an angle adjuster connecting plate. The front portion of the lower end of the angle adjuster connecting plate is connected with the rear end of the seat cushion side plate to form a first connecting structure, the rear portion of the lower end of the angle adjuster connecting plate is connected with the rear end of the seat cushion side plate to form a second connecting structure, and the second connecting structure is a bolt connecting structure. The first connecting structure is an energy absorption connecting structure composed of an energy absorption part, an upper end bolt connecting structure and a lower end bolt connecting structure. When a rear-end collision occurs in a vehicle adopting the device, the vehicle cannot be collided; passengers have very large impact force on the seat backrest; the energy can be transmitted to the cushion sideplate by the angle adjuster connecting plate through the upper end bolt connecting structure, the energy absorbing part and the lower end bolt connecting structure in sequence; therefore, in the impact process of automobile rear-end collision, the upper end of the energy absorption part and the upper end bolt connecting structure slide backwards along the arc-shaped sliding groove together, the energy absorption part is stretched and deformed in the process, and buffering and energy absorption are achieved.
本发明公开了一种拉伸式追尾碰撞座椅吸能结构,包括坐垫侧板和调角器连接板,调角器连接板的下端前部与坐垫侧板的后端部连接形成第一连接结构,调角器连接板的下端后部与坐垫侧板的后端部连接形成第二连接结构,其中,第二连接结构为螺栓连接结构;第一连接结构为由吸能件、上端螺栓连接结构和下端螺栓连接结构组成的吸能连接结构。采用本发明的车辆发生追尾碰撞时,乘员对座椅靠背非常大的冲击力,能够由调角器连接板依次通过上端螺栓连接结构、吸能件和下端螺栓连接结构传递至坐垫侧板,由此,在汽车追尾碰撞的冲击过程中,吸能件的上端部和上端螺栓连接结构一起沿圆弧形滑槽向后滑动,吸能件在此过程中拉伸变形,实现缓冲吸能。
