The invention discloses a quick-response active protective headrest device of an automobile seat and a control method of the quick-response active protective headrest device. The quick-response active protective headrest device of the automobile seat comprises a seat body. A headrest is connected with two supporting rods. The two supporting rods are connected with a U-shaped support. The lower end of the U-shaped support is connected with a smoke type driver. Push rods of the smoke type driver can push the headrest to move upwards and forwards. The control method of the quick-response active protective headrest device of the automobile seat comprises the following steps that (1) a rear collision sensor is connected with a vehicle-mounted electronic control unit (ECU), and an electronic trigger is connected with the vehicle-mounted ECU; (2) the vehicle-mounted ECU is started and conducts self-inspection; and (3) when the variable quantity of the impact speed is equal to or larger than 10 km/h, the smoke type driver is detonated, and the headrest is pushed to move upwards and forwards. According to the quick-response active protective headrest device of the automobile seat and the control method of the quick-response active protective headrest device, quick response is achieved, in this way, the backward movement ranges of the head and the neck can be effectively limited when collision occurs, and injuries to the head and the neck can be avoided or relieved.
