The automobile seat also plays a role in safety, when the head of an automobile is collided and is stopped suddenly, a human body can generate corresponding inertial motion, but due to sudden accidents, the body of the human body moves forwards along with the automobile seat, but the head of the human body still keeps still, so that the neck of the human body can be injured in a short time, and therefore, the headrest on the seat is a necessary part. The existing headrest and the backrest of the seat are of an integral structure, and when the backrest is adjusted, the headrest is adjusted along with the backrest. As each person has different comfort requirements on the angle of the backrest, the angle can be adjusted to different angles, but the headrest can also rotate together, when the headrest leans forward along with the rotation of the backrest, the head can touch the headrest, but the back of the person does not touch yet, the person can not feel uncomfortable when forcibly leaning against the headrest, and the sight cannot normally see the front; when the headrest leans backwards along with the rotation of the backrest, although the back of a human body is comfortable, the headrest is too far backwards, the function of protecting the head from bending backwards is lost, and the neck of the human body can be injured when an accident happens.
