The invention discloses an active headrest protecting the neck safety of passengers. The active headrest comprises an air cylinder, a control module and a frame body. The frame body is arranged in the headrest in a sliding mode, and a head plate is arranged at the open end of the frame body and is connected to the output end of the air cylinder. A regulating rod is installed on the end of the part, opposite to the output end, of the air cylinder, one ends of connecting rods are hinged to the regulating rod, and moving blocks are installed at the other ends of the connecting rods. Two trapezoid grooves matched with the moving blocks are formed in the inner side wall, opposite to the regulating rod, of the frame body. When the distance between a vehicle and another vehicle behind the vehicle is within a safety value range, the control module directly controls the air cylinder to retract, the output end of the air cylinder drives the head plate to move backwards, and therefore the heads of the passengers and the supporting part of the headrest can be reset, manual operation is not needed, protection synchronization of the headrest and a vehicle safety system is achieved, and the reliability factor of the driving safety of the vehicles is increased.
