Have you ever tried to take a run and stuck against a wall? No? It is understandable: brain concussion, broken nose and other injuries can not be avoided. Something similar happens when you crash at 40 km/h, if you are not wearing seat belts.
There is nothing is more terrible than the fate of a driver and a passenger, who at the time of a traffic accident (run down on a stationary barrier at a speed of 80 km/h) were not wearing seatbelts. Force, 30 times exceeding car’s weight, stops its movement. The passengers, if they are not belt up continue to move in the cabin at a speed of 80 km/h. In 0.05 seconds the speed decreases and passengers experience the gravity force 80 times more than their own weight! The driver with the force of 9 tons hits the dashboard, and in another 0.02 seconds, the driver and the passenger ram their heads into the windshield of the car and get fatal skull injury.
Impressive? Remember, how a newborn can not keep his own head. In the same way an adult can not keep his head in the moment of machines blow with of the obstacle. No wonder, it is like a piece of lead poured by forces of the negative acceleration, and it begins to weigh up to 600 kg. Similarly, the body turns under the influence of those forces into the bag of bones, but very heavy bones. A person in this state can literally fly through the eye of the needle and surely fly out of the car at a crash moment through the side or windscreen.
National Highway Traffic Safety Administration reads:
When used properly, lap/shoulder bets reduce the risk of
fatal injury to front–seat passenger car occupants by 45%
and the risk of moderate-to-critical injury by 50%. Even
greater risk reduction results when belts are used properly
in light trucks.
So, the conclusion is clear – sit in the car and fasten your seat belts! They not only reduce the effects of trauma, but also fix the body in turns.
Belts in the city
How to understand the driver, who says that he does not belt up in the city – why? Belts disturb, but outside the city on the highway, he will belt up. Maybe someone else will say that seat belts are not needed at all in the city?
In many countries the obligation to fasten seat belts extends even on back passengers. And in the U.S., according to the scientists, the introduction of compulsory seat belt use has reduced the number of casualties on the roads on 40%. Simple Arithmetic.
Committee for the Safety Belt Technology Study estimate the situation in such a way:
If current belt nonusers in passenger vehicles buckled up,
thousands of deaths and hundreds of thousands of injuries
could be prevented each year at an estimated societal
savings of $26 billion in medical care, lost productivity,
and other injury-related costs.
When the belts do not work?
Overloads acting on the driver and passengers in an accident are really great. Even a man with a safety belt can get serious injuries, but more likely he will stay alive! Belts do not save from injuries in bumps from one side or from the back side. If your car has overturned, it is likely to hurt your head, you can slip out from under the straps. No doubt racers are much better protected. From the lateral displacement they are supported by seats, the frame of safety provides crease-resistant zone, helmet saves head from injuries. But in 90% of cases it is an ordinary seat belt saves driver’s life.
Once the German television interviewed Christian Danner, a former racer, now driving instructor and journalist. He said that before a tour at a high speed he always takes away his trouser belt. Because its large metal buckle in an accident under pressure seatbelt can rip the abdominal cavity as a razor. It is recommended to remove even the outerwear. Moreover the breast pockets should not contain pens, mobile phones, cigarette lighters. The cell phone under his seatbelt produces only compression of tissues, then the pen at a certain angle can easily pierce driver’s heart. Even the usual button can cripple, because seat belts restrain human body during the impact, whose weight, even for a split second, reaches several tons weight.
