The invention discloses a passive movable head protection system belonging to the technical field of automobiles. The passive movable head protection system comprises a vehicle body, a fixing plate, supports, a push-pull rod, a motor, a wire harness and a stress inductor. The lower end of the front support and the lower end of the back support are arranged in a groove of the fixing plate, and the upper end of the front support and the upper end of the back support are fixedly connected through the lower end of a vehicle seat. The two ends of the push-pull rod are connected with the back support and the motor respectively. The stress inductor is arranged on a cover lid of the vehicle body or on the top of the vehicle body. According to the passive movable head protection system, when an electronic control unit monitors that the front portion or the back portion of an automobile collides or an object falls down from the upper air through the stress inductor, the vehicle seat is moved forwards or backwards through the motor, and therefore the injury degree of a driver is reduced. The passive movable head protection system is reasonable in structure, simple in design and suitable for the optimization design of an automobile crash loss reducing system.
