A brief history of children's car safety seat design
At the beginning of the 20th century, cars began to be gradually popularized in developed countries, but the high-speed development of cars was still after the Second World War. In particular, the development of the highway has made the car overpass the train, and the multi-functional children's high dining chair has become the first major transportation method. The ensuing traffic safety problems are also becoming increasingly prominent, blow molding processing has aroused widespread attention of the public. How to deal with traffic safety has become a big issue.
The advent of adult seat belts and airbags has saved countless lives. According to statistics, wearing a seat belt can reduce 46% of deaths and 67% of serious injuries may, because children's bones are young, when the car crashes, speed sensitivity is reduced, people will be due to huge inertia and rush forward, at this time the diagonal body of the strong seat belt may constitute a child's chest rib fracture, suffocation and neck fracture risk. Adults are much less at risk. Seat belts are still ideal for traditional safety equipment, but for children, seat belts can sometimes be fatal. In the United States, 10,000 fewer people die each year. All vehicle safety equipment is designed for adults. Take the three-point seat belt as an example, because the height of the seat belt is not scheduled (some high-end cars in the front seat belt can do 0-20cm height scheduling), its planning is almost based on the ordinary height of the adult planning.
Likewise, airbags are unsafe for children. An inflating air bag could strike a child with enough force to cause serious injury. In 1999, the vast majority of the 150 people killed by airbag detonations in the United States were children. Airbags are designed for adults. The inflation process is completed at the moment of the crash, so the rate of inflation is very intense, about a few milliseconds with explosive gas to fully inflate a nearly 100 liter air bag.
High-speed car safety seat refers to the safety seat that can pass the impact test specification of more than 60KM/H. Europe, the United States and China's national norms require that the child safety seat must go through 48, 50KM/H impact test, and the child's chest component acceleration does not exceed 55g. Goodchild high-speed car safety seat beyond the national standards, European standards, the performance of qualified impact speed increased to more than 60 kilometers per hour, and in 60, 70, 80 kilometers per hour impact test, to maintain the indicators are qualified.
