The development history of car seat belts
In 1885
Seat belts appeared and were used on carriages to prevent passengers from falling from the carriages.
May 20, 1902
At a car race in New York, a racing driver used several belts to prevent him from being thrown out of the car at high speed. He and his companions were tied to their seats. During the competition, the car they were driving accidentally crashed into the crowd of spectators, killing two people and injuring dozens of others. However, these racing drivers escaped death because of their belts. These belts became the prototype of car seat belts. When used for the first time in a car, they saved the life of the user.
In 1922
Safety belts began to be used in sports cars on the racing circuit;
In 1955
Ford made the safety belt configuration a standard optional, and the first model with standard seat belts was the Saab 93 GT750.
Although more and more cars are equipped with seat belts, the seat belts installed in cars at that time were two-point seat belts tied around the waist. Due to design flaws, these seat belts are still There is a safety hazard. When the car brakes suddenly or collides, it is impossible to avoid the driver's head hitting the steering wheel or windshield, causing casualties.
In 1959
Volvo engineer Nils Bohlin invented the three-point seat belt. Safety test results show that vehicles using this three-point seat belt can greatly reduce the risk of vehicle accidents in the event of a collision. The probability of casualties of personnel inside.
This invention has a far-reaching impact and has saved tens of thousands of people’s lives in accidents from its birth to today. Moreover, it was rated as one of the eight most important inventions in the past 100 years by the German Patent Office.
In 1968
The United States stipulated that all forward-facing seats in cars must be equipped with seat belts. Subsequently, developed countries such as Europe and Japan have successively formulated regulations requiring car occupants to wear seat belts
1992
The Ministry of Public Security of my country issued a notice on November 15, 1992 , which stipulates that from July 1, 1993, drivers and front-seat passengers of all passenger cars (including cars, jeeps, minivans, and mini-cars) must use seat belts.
After more than 40 years of development, car seat belts have gradually matured. Today's seat belts are made of extremely strong synthetic fibers and have self-locking retractors. The three-point design restrains the shoulders and waist of the driver and passenger at the same time.
