The invention discloses a method for adjusting an automobile seat headrest with a protection function. The method comprises the following steps: firstly, a control module electrically connected with a cylinder is directly communicated with an automobile active safety system; when a distance of a vehicle behind to the present automobile is within a dangerous value range, the control module directly transmits a command to the cylinder so that an adjusting rod drives a head plate to move forwards, leading to that a supporting portion of the headrest gets close to the head of a passenger; in the movement process of the head plate, a fixed block is mounted on the adjusting rod and a connecting rod A, a connecting rod B and a connecting rod C are arranged on the fixed block, a bottom surface of the head plate and an inner sidewall of the frame, whereby the movement of the head plate is supported by the inner walls of the two sides of the frame and the fixed block simultaneously; when a distance of the vehicle behind to the present automobile is within a safe value range, the control module directly controls the cylinder to retract and the head plate directly falls into a rectangular groove so that the head of the passenger and the supporting portion of the head rest return, and therefore, synchronization of headrest protection and the automobile safety system is realized.
