Seatbelts and Airbags have become very important features of the new Japanese Cars as companies like Toyota have stressed the significance of a car to meet the Car Safety standards in order to avoid dreadful accidents and saving lives. There are lots of people in the world who prefer to buy Japanese Used Car and they also prefer to buy used car with Seatbelts and Airbags.
Initially there was a lot of debate about whether the seatbelts are a means to protect against accidents. However, research has shown that people have been safe even after a dreadful accident because of this feature in their vehicles. Hence, this is why the presence of seatbelts and airbags has become so important to incorporate in almost all car manufacturing units. While seatbelts hold you back, airbags are soft pillow like cushions which prevent your head to hit the window or the windshield. Thus the presence of these two features at least minimizes the magnitude of shock and potential injury to those sitting in the car.
How Seatbelts & Airbags Work
So it is important to understand how seat belts and airbags actually work. These features work on laws of motion and are incorporated in the cars as part of safety measures and legislation in the country. So the laws of motion stipulate that when an object of force is moving, it has a certain momentum which can only be broken down by an outside force. This is true in case of the car as well as the passengers sitting inside it. The passengers are moving at the same speed as the car and in an accident, the airbags act like that external force that halts a stop to the movement of people sitting in the car. So while seatbelts hold you back from jumping out of your seat during an accident, airbags prevent any head injury that otherwise would be very likely to happen. This is because the head is more likely to crash into the windShield.
The air bag in particular has three parts; the bag itself, the sensors and the inflation system. The bag is made up of a think fabric usually nylon which is folded into the dash board and steering wheel in Japanese cars. The sensors send signals to the bag to inflate. The detection of these sensors is smart and can be equivalent to bumping into a brick wall at the speed of 10 to 15 miles per hour which roughly makes 16 to 24 kph. The inflation of the air bags comes from the sodium azide and potassium nitrate. Both of these elements react too quickly in order to produce the hot nitrogen gas through which the bag inflates and as it expands, it is popped out of the dash board or steering wheel. In just a second the bag will deflate which means it has holes to quickly enable you to see where the car is heading.
Thus it is very important to learn about the usage of these features as they can be life saving in an accident that could otherwise take your life away.
