The invention discloses a car collision active safe headrest device which comprises a seat backrest skeleton and a headrest skeleton which is arranged above the seat backrest skeleton, wherein supporting clamping boards are symmetrically arranged on backrest side boards on the two sides of the seat backrest skeleton, inserting holes are formed in the supporting clamping boards, the two ends of a U-shaped triggering rod horizontally arranged in the middle part of the seat backrest skeleton are movably inserted in the inserting holes, returning springs are respectively arranged on the two ends of the U-shaped triggering rod, the other ends of the returning springs are connected with the backrest side boards, a linkage board extending upward is hinged in the middle part of the U-shaped triggering rod, and the headrest skeleton is fixedly connected onto the upper end of the linkage board through a connecting frame. The car collision active safe headrest device has the advantages of being simple in structure, light, convenient, safe, stable and low in manufacturing and maintaining cost. Under a normal condition, the U-shaped triggering rod and the sponge inner side of the seat backrest are in an attaching state; when a rear-end collision or an emergency brake occurs, the U-shaped triggering rod can drive the headrest skeleton to move forward and effectively protect the neck of a passenger.
