The utility model relates to a multistage efficient energy absorption headrest. Wherein the fixing plate is located in the headrest and fixedly connected to a headrest rod, the pressed plate is located in front of the fixing plate and moves front and back relative to the fixing plate, and a buffer folder located in the middle and a pair of spring expansion type crushing pipes located above and below the buffer folder are arranged between the fixing plate and the pressed plate. The energy absorption device of the multistage efficient energy absorption headrest is small in occupied space, can beused for efficiently absorbing energy generated by collision to a large extent when a person collides with the automobile seat headrest, cannot cause secondary harm to the human body after energy absorption is completed, and reduces harm of impact energy to the person. 本实用新型涉及一种多级高效吸能头枕，包括位于头枕内并固定连接与枕杆上的固定板和位于固定板前方并相对固定板前后移动的受压板，所述固定板和受压板之间设置有位于中间的缓冲折叠器和位于缓冲折叠器上、下方的一对弹簧膨胀式压溃管。本实用新型多级高效吸能头枕的吸能装置占用的空间小，可用于人与汽车座椅头枕发生碰撞时进行较大
