Explanation of Seat Belt Knowledge

Car seat belts - things you don't know about

When it comes to seat belts, probably no one is unfamiliar. Every car has seat belts, but with such a simple looking belt, its background is not simple.

In fact, seat belts had already appeared before cars appeared, and they were used on carriages at that time. The history of the carriage has a long history, almost as long as human civilization. Around the 16th century, the nobles and nobles of various European countries began to use carriages as a means of transportation. In order to ensure that they were not thrown out of the carriage, they installed safety belts on the carriages.

Later, the seat belt was used on the plane by a famous scientist, George Cayley, who was known as the father of modern aerodynamics.

He has been researching gliders all his life. When he asked his family's coachman to conduct glider experiments, in order to ensure the safety of the coachman, he tied a belt to the coachman, and this belt actually became the earliest record of human use of safety belts. Of course, the coachman resigned angrily afterwards and was probably taken by a glider to soar around, greatly frightened.

More than 30 years after this incident, the two-point safety belt used by George Cayley was applied for patent. The applicant was an American named Edward. The application date was 1885.

But the seat belt on this patent is still used for carriages. After the emergence of cars in 1886, such seat belts were not used for a long time.

In the following years, two-point seat belts continued to be used on carriages and airplanes, and Benjamin, the father of American aviation, equipped them on airplanes to ensure smooth takeoff and landing.

During World War I, the famous ace pilot Adolf Pergo also used it to ensure his own safety.

Although seat belts have been widely used in airplanes, no one has ever used them in cars. Until a race car in 1902, contestant Walter Beck temporarily added a belt to the seat due to a loose seat. As a result, an accident occurred during the race, resulting in nearly ten deaths and injuries on the spot. Unfortunately, Walter Beck survived due to the protection of that belt, but this did not attract attention to this belt.

Twenty years later, another racing driver added a seat belt to the car to ensure their own safety, but these practices were not promoted.

It wasn't until the 1950s that people began to add seat belts to cars. In 1957, Ford introduced the world's first model with all standard two-point seat belts, the Saab 93Gt750, which used the two-point seat belts on airplanes.

But soon, this type of seat belt proved to be imperfect, as although it can save a person's life in a car accident, it can cause serious brain damage.

Just as people discovered the shortcomings of two-point seat belts, someone invented the Y-type three-point seat belt and applied for a patent, which is much more powerful than two-point seat belts.

But this type of seat belt has not been widely applied yet, and a big shot has emerged. In just one year
