Seat belts are a small but indispensable part of every car. They are very important in helping us to ensure safety as the name implies.
If you don’t wear your seat belt correctly, it won’t work either.
So do you know how to use car seat belts and replace them when they need to be replaced?
The following article will provide all the information you need to know about car seat belts.
Origin and working principle of car 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).
The Importance of car seat belts
The importance of car seat belts is well known. But a lot of people are still distracted and they ignore wearing seat belts while driving.
So we’re going to reiterate once again the benefits of wearing seat belts.
Wearing seat belts prevents people from being thrown with great force, avoiding crashing into the glass or hitting your head on the steering wheel when your car is stopped suddenly.
As a reminder, there have been many cases of death for not wearing a seatbelt while driving.
When the car is racing at 70km/h, the occupants of the car also reach an inertial speed close to that speed.
If you wear a seat belt, you will be restrained in the event of an abrupt stop, otherwise you will move forward up to 70km/h.
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.
Currently, in most countries around the world, there are laws that make it mandatory to wear a seat belt when using a vehicle. And we also have to use baby seat belts in the car. If you do not wear a seat belt, you will be fined a large fine.
