[0002] Child seats are protective seats designed specifically for children. Many parents mistakenly believe that holding their children in their arms and sitting in the front passenger seat is the safest way. In fact, parents who are eager to protect their children often underestimate the impact force generated by a vehicle collision. Children in the front passenger seat are often easily crushed by the pop-up airbags. Shi Xiaoguang, president of the China Toy and Baby Products Association, pointed out in an interview that the correct use of child safety seats can effectively reduce the death rate of children in traffic accidents by 70%. In order to improve the convenience and safety of the buckles for fixing child seats when in use, it is necessary to propose child seat buckles.
