11.Having worked as a plane designer before,Nils knew clearly that the pilots were willing to put on anything to keep them safe in an accident,but to his surprise,most people in the cars just didn't want to be uncomfortable for even a minute.To improve the safety for people in the cars,he decided to find a perfect system which should be simple,effective and convenient.In the end,he invented the three-point seat belt,which has been considered as one of the greatest inventions in history.
Seat belts prevent people in the cars from serious injury in five ways.
Keep people inside.People who are thrown out from a car are four times more likely to be killed than those who stay inside.
Protect the strongest parts of the body.Seat belts are designed to fix your body at its strongest parts.For an older child and adult,these parts are the hips (臀部)and shoulders.
Spread out the force in an accident.Seat belts spread the force of the accident over a wide area of the body.By putting less stress on one area,they can help you avoid serious injury.Seat belts also help keep your upper body away from the hard parts of the car if you stop suddenly or are hit by another car.
Help the body to slow down,A quick speed causes injury.With the help of the seat belts,your body can have more time to slow down in an accident.
Protect your brain and spinal cord (脊柱).Seat belts are designed to protect these two key areas of the human body.Head and spinal cord injuries may be hard to see immediately,but they can cause death.Therefore,it's of great importance to protect these parts.
