How to use and replace seat belts


Before getting to know how to use and replace seat belts, let’s go through some basic knowledge about these amazing things. 

Car seat belts were invented in the 19th century and they have become standard, mandatory equipment on all cars. 

Wearing a seat belt when driving a car helps keep you tight, helps you avoid collisions when the car stops suddenly, and minimizes injury which may occur in the event of an accident.

Its working principle is pretty simple. It resists the force of inertia. 

It is fastened to the body of the vehicle to keep the body firmly attached to the seat and to distribute the force to the healthy parts of the body to minimize danger. 

When the seat belt is properly fastened, the force is distributed to the strongest areas of the body such as the ribcage or pelvis.

The collision sensor senses vibrations and then contacts the belt control unit to activate the automatic re-tightening mode when a collision occurs. Thanks to that, we are kept firmly and not thrown out.

There are two types of car seat belts: the traditional seat belt is a lap belt (usually pulled over your hips) or a shoulder belt (pulled over your shoulder).

According to some research, if a person weighs 70 kg, the impact force is up to 3 tons when the car is running at 70 km / h and the impact force is up to 9 tons if the speed is 80 km / h. You can totally imagine what the consequences would be.
