With the help of safety belts, traveling by car has become much safer. It is estimated that each year the wire saves the lives of more than 1 million people and contributes to preventing about 100,000 other deaths.

Purpose of seat belts

Seat belts

From an optional equipment to a standard equipment, seat belts play an increasingly important role in ensuring the safety of people who use cars to travel. The purpose of inventing this device is to keep the person sitting inside from being knocked out or rushing forward when the car stops suddenly, saying more professionally is to destroy the inertial force . For example, if a car is moving at about 60 km / h suddenly and hitting an obstacle on the road, the driver will risk hitting the steering wheel, but if the speed is 100 km / h h the people in the front row can plunge into the windshield and at the moment, head injury is very unavoidable.

"Father" of safety belts

Nils Bohlin - the "father" of the 3-point seat belt

The safety belt fitted to all vehicles is now a three-point belt invented by Nils Bohlin - an engineer at Volvo in 1959. However, in the 30s, seat belts were used. Used as a passive safety solution for aircraft and 20 years later, in 1956, Ford also decided to invest in equipment for its vehicles as a way to ensure safety for the aircraft. users as well as increase the attraction for the product.Unfortunately, this type of belt is not strong enough to eliminate inertia, resulting in the number of deaths in accidents still not really relieved.

2-point seat belt

In 1958, Volvo decided to hire Nils Bohlin to work on a more innovative seat belt, and in 1959 Nils launched its product as a 3-point belt . With this belt, almost every weakness discovered when using the 2-point seat belt is overcome as the ability to hold the chest, shoulders, pelvis, helps the sitting person not to rush forward or throw out.

3-point seat belt

Since this time, a lot of research and improvements have been made. By 1967, seat belts were fitted to the rear bench; In 1986, applied to the middle bench and in 1993 was the time of the mark due to the installation of three-point seat belts on all types of vehicles. Although, at present, the belt has had some minor changes in belt tensioners such as automatically tightening on the body of the person sitting on the sensor or a number of modern cars that have integrated this equipment. With some other systems, in general, safety belts still play an extremely important role.
