The birth of three point safety belt

Seat belts were first seen in the field of aviation, in order to prevent pilots from falling out of the cab. 1n fact, there have been some patent designs for seat belts of motor vehicles. Perhaps the oldest of them was born in 1885 in the United States, which coincides with the advent of cars. After entering the 20th century, a French patent came into being: a safety system including a waist belt and a shoulder belt covering the chest. Meanwhile, another seat belt patent was approved in the UK, although the invention was first widely used in the United States. 1n the 1980s and 1920s, although American car racing was famous for its speed, the cars used were not very stable. 1n 1922, a car racing celebrity first used and displayed seat belts in the United States

at that time, in the United States, some doctors began to install homemade seat belts in their cars. 1n the 1930s, some American doctors called for the installation of seat belts in all cars in newspapers, but this did not attract people’s attention

History of safety belt

pull out, lengthen, buckle in and tighten – the safety belt can be put in place through a series of simple manual operations, reducing the risk of death and serious injury caused by collision by more than 50%. Seat belts are the link between people and cars. 1n the 55 years since Volvo pv544, the first car equipped with three-point seat belts in the world, was put into use, more than 1 million lives have been saved. Volvo selflessly opens this technology free of charge, any automobile manufacturer can use this design free of charge

the birth of three-point seat belt

in Sweden, engineer Nils Bolin has been working in Saab’s aviation department since 1940s. 1n 1955, he was responsible for the development of seat catapults and other safety equipment for pilots. 1t was Nils Bolin who designed the seat catapult and its peripheral equipment for the Swedish fighter j35draken

in 1958, Nils Bolin was recruited by the then president of Volvo, Genna engelio, and was appointed as the chief safety engineer of Volvo. Unlike others, Genna engelio released the company profile and felt the importance of emphasizing safety, which had become an important part of Volvo’s corporate image at that time

in 1958, Volvo’s pursuit of effective safety solutions resulted in the patented invention of Nils Bolin’s three-point seat belt. The four most important elements of his design are: the system is composed of a shoulder type seat belt and a waist type seat belt. The fixed point of the seat belt is located at a low point next to the seat. The seat belt forms a V-shape pointing to the ground. The seat belt is always fixed and will not move even in a collision

in 1959, this patent of three-point seat belt was applied to Volvo Amazon (120) series and pv544 Series in the northern European market. As a result, Volvo has become the first car manufacturer in the world to use seat belts as a standard configuration. Since then, the three-point seat belt has been widely used in cars, which has also brought happiness to automobile consumers all over the world
