Hundreds of thousands of people are injured every day in car accidents, and tens of thousands of people are killed. This was done by designers and car makers to find appropriate solutions to prevent and minimize the consequences of these accidents. The seat belt is one of the most important traffic safety techniques to solve This problem has, God willing, played a major role in reducing deaths and reducing injuries. Statistics from the National Highway Security and Traffic Administration in the United States show that the safety belt saved about 12,000 people in the United States during 2000. , And that about 9000 N victims in 2000 they could avoid death if they used a seat belt.
The main idea of the seat belt is to prevent the passenger from colliding with the car's battery or from bumping into it through the windshield when the vehicle suddenly stops as a result of a collision, because the passenger's body gains speed but does not have the ability to stop abruptly.
The belt was first introduced in American cars in 1947, and in 1956 Ford supplied the belt in cars to be sold inside America. In 1964, the belt became standard for American cars. Two years later, the back belt became standard, and in 1967 the front belt became mandatory, and only a year later, the shoulder belt became mandatory, in 1968.
Most modern seatbelts are connected to the chassis by three points, two inside the chassis and the third beside the passenger, which is used to tie the belt.
The control unit detects the movement of the electronic or mechanical sensors that respond to the sudden decrease in the speed of the vehicle as a result of the collision. The processor gives the signal for the charge to work, and then the air bags will be released in the cars if equipped.
