Giving up the routine of wearing seat belt when being in car, you are accidentally put yourself in danger.
Many people feel that it’s so complicated, or even do not know all uses of seat belts which are set up in each car, so they do not have a routine of wearing them. In addition, some consider that only drivers or people in the first must fasten seat belts.
However, according to a research of the Insurance Institute for Highway Safety (IIHS) (a U.S. nonprofit organization funded by auto insurers, established in 1959 and headquartered in Arlington, Virginia), despite being in the front or back bench seats, people are put in danger if forgeting to fasten seat belts. The strong crashes can make everyone in car suffer injuries, in some bad conditions, we may not save our life.
For example, if a person in back bench seats doesn’t wear his seat belt, the inertia force will push not only him toward, but accidentally the people in front bench to the driver’s hand, which can cause driver steer wheel suddenly and make the unexpected accidents for everyone inside car.
Inertia force occurs when the vehicle is running at a speed of 60 km/h, then brakes suddenly, the inertia force will be made and push the person seating forward with the relevant speed.
When the vehicle runs at 70 km/h, the impact force in people weighing about 70 kg must bear up to 3 tons. At 80 km/h, this force is up to 9 tons and multiply as the velocity increases.
According to a study by the Centers for Disease Control and Prevention (USA), the probability of being thrown away the seat will increase 30 times and 75% will pass away due to the injury in this type of accident.
According to the statistics from Switzerland, the promulgating a law of fastening seat belts has decreased 1/3 of the accidents caused by forgeting to fasten seat belts.
In Japan, the number of statistics indicates that the seat belt has saved 75 of the 100 victims in the car accidents.
