1. Seat belts, as a basic protection device to protect drivers and passengers during car collision, were born before cars. As early as 1885, seat belts appeared and were used in carriages to prevent passengers from falling off the carriages. 1902 On May 20th, in a car race in new york, a racer tied himself and his companion to his seat with several belts to prevent him from being thrown out of the car at high speed. During the race, the car they were driving accidentally rushed into the audience, causing two deaths and dozens of injuries, but these racers escaped because of their seat belts. These seat belts have also become the prototype of car seat belts. When they were first used in cars, the lives of users were saved.
2. The standard form of safety belt in the world is the three-point safety belt invented by Niels. 1967 began to accept this kind of car seat belt. Niels published the "28,000 Accident Report" in the United States, which recorded all the traffic accidents of Volvo Cars in Sweden in 1966. The figures clearly show that three-point seat belts not only reduce or even avoid the chances of passengers being injured in more than half of the cases, but also save them.
