[0002] Generally speaking, child safety seats are divided into infant safety seats and child safety seats. From the perspective of usage, they are generally divided into two types: lying down and sitting. From the time the baby is born to the time when he can sit independently, an infant safety seat should be used. After the baby can sit independently, you can switch to an ordinary child safety seat. Specifically, it is divided into three types according to the type of fixing method: European standard ISOFIX fixing method, American standard LATCH fixing method and seat belt fixing method. When the child's intelligence and physical development reach a certain level, his curiosity also begins to become strong. He does not like to sit quietly in the chair, but likes to stand up and touch and shake the back of the chair. In this way, it is difficult to ensure the safety of the child, especially when the parents are not paying attention and leave for a while, the child is prone to accidents. Therefore, how to make the child seat safer is a problem worth solving.

[0003] After searching, it is found that a car child safety seat is disclosed in Chinese patent documents [Application No.: 202321125803.0; Publication No.: CN 220410500 U]. A car child safety seat comprises a seat and a backrest, wherein a backrest is installed on the top of the seat, the backrest is installed on the top of the seat, and detachable absorbent cotton is installed on the surface of the seat and the backrest, and a safety belt is installed on the surface of the backrest, wherein four safety belts are installed on both sides of the top of the backrest and the left and right sides of the bottom, respectively, and the safety belt comprises a safety rope, a first adjustment ring, a second adjustment ring, a connecting rope, a connecting ring, a first fixing block and a fixing block, and a safety lock buckle is installed on the top of the seat, wherein the safety lock buckle comprises a second fixing block, a limiting hole and a third fixing block, and a safety rope is fixedly installed on the surface of the backrest, and the safety rope extends into the backrest. The car child safety seat can effectively fix the child on the child seat, and plays a buffering role in the event of an accident, thereby preventing the child from causing secondary injuries, and is more practical.

[0004] Although this patent can effectively fix children in child seats and act as a buffer in the event of an accident to prevent children from suffering secondary injuries, the seat in this patent is an integral structure, so that after being fixed to the vehicle seat, the direction in which the child is facing cannot be changed. This makes it impossible to change to the reverse direction when there is heavy traffic to improve protection, or to change to the forward direction on safe roads, reducing the fun of children's outings.
