The invention discloses an active headrest use method. The use method comprises the following steps that a control module electrically connected with an air cylinder is communicated with an automobile active safety system; when a distance between a vehicle behind an automobile and the automobile is within a dangerous value range, the control module directly transmits an order to the air cylinder; an output end of the air cylinder extends and drives a head plate to move forward, so a supporting part of the headrest closes to a driver head; when a distance between the vehicle behind the automobile and the automobile is within a safe value range, the control module can directly control retraction of the air cylinder; and the output end of the air cylinder drives the head plate to move backward and the driver head and the supporting part of the headrest reset. Manual operation is unnecessary and synchronization between the headrest protection and the automobile safety system can be achieved and reliability coefficient of the automobile driving safety can be enhanced.
