when the automobile seat works, the safety air bags are arranged in different positions of the automobile seat under the condition that an automobile has no accident, so that the normal use requirement of the automobile seat is not influenced; the left side of the automobile is designed into a U-shaped structure, so that the riding comfort of the passengers is met, and the stop handrails on the two sides can prevent the left side and the right side from sideslipping, so that the passengers are effectively prevented from sliding down laterally due to transverse centrifugal force when the automobile runs on an annular road, and the safety is improved; when a forward collision accident occurs, people often lean forwards due to the inertia effect, and the safety airbag is mounted on the steering wheel at the driving position, so that the face or the head of a driver can be effectively prevented from being injured due to the collision of a front object, but the driver is not completely protected for a rear passenger, and is often easy to collide with the back of a front seat to be injured during the passenger accident; therefore, the third safety airbag 15 is arranged on the side surface of the backrest 11, which is far away from the seat plate 1, so that the probability of accidents is effectively reduced; when accidents such as lateral collision or incontrollable tire burst of the automobile occur, the automobile can have a serious tail flicking phenomenon, and passengers are easy to collide left and right to cause injuries, so when the lateral acceleration of the type is large, the sensor senses a signal and transmits the signal to the controller, the controller controls the generator to react, the first safety air bag 13 and the second safety air bag 14 on the left side and the right side of the automobile seat are popped out, the passengers can be effectively fixed, and the passengers can be prevented from swinging or sideslipping left and right by a large margin to cause injury accidents; when the forward inertia effect is weakened in an accident, the passenger is often pulled back to the seat under the action of the safety belt, and the neck of the passenger is easily subjected to large impact, so that the neck is effectively protected by fixedly connecting the same neck protection air bag 31 on the front end surface between the backrest 11 and the headrest 3, and the risk of neck injury is reduced; when an accident occurs, because the safety belt pulls the passenger back to the seat, a large head impact is easy to generate, the headrest 3 in the prior art is often of a fixed structure and has a poor buffering effect, the same rotating supports 21 are fixedly connected at the symmetrical positions of the left side and the right side through the upper end surface of the backrest 11, the same headrest 3 is connected on the rotating supports 21 in a rotating mode, meanwhile, the first springs 32 which are uniformly arranged are arranged between the headrest 3 and the backrest 11, so that the headrest 3 can rotate forwards and backwards, and when the head of the passenger collides with the headrest 3 in a heavier mode, the rotation buffering can be effectively carried out; when a driver drives the automobile for a long time, legs are suspended for a long time, so that fatigue is easy to generate, the automobile seat in the prior art cannot meet the requirement of relaxing the legs when the driver drives the automobile, and therefore the support plate 2 is rotatably connected to the front end face of the seat plate 1, so that the support plate 2 can be adjusted to support the legs according to the requirement when the driver drives the automobile, the situation that the legs are not suspended for a long time and exert force is avoided, the legs are aching and influence on driving is avoided, and meanwhile, the fatigue feeling of the legs can also occur when the driver drives the automobile seat for a long time;
