There have been debates regarding whether seatbelts really give any protection. The reply to this question is simple. Seatbelts serve as a passive restraint in cars. Almost everyone has adopted seatbelts as a safety measure in cars. With time statistics have also proved that seatbelts have saved thousands of lives from car accidents. Similarly, airbags play a huge role in minimizing the level of hurt during accidents. They are the soft pillow cushions, which spreads the thrust of the strike and minimizes the shock.
Airbags have helped to reduce the frontal crash injury to around 66%. The seatbelts and airbags installed in cars as safety measures work on laws of motion which are needed to be understood in order to understand how the airbags and seatbelts work?
The object that is in motion has a certain amount of momentum, which continues to move until and unless some outside force does not stop it. In order to stop a moving object a certain amount of force and time is required. When the car is moving at a certain speed, the passengers are also moving at the same speed as the car. Hence the airbag tries to bring the motion of the passenger from a certain speed to zero speed within a fraction of second by inflating itself in between the passenger and the steering wheel or dashboard. This helps to protect the passenger from getting hurt.
Similarly, the seatbelts also work on the laws of motion. The role of a seatbelt is to stop the passenger from jumping off the seat and dash into the car objects during a car crash.
When the car moving at the speed of 100 km/hour suddenly comes to halt or strikes something, the seat belts help to restore the inertia of passengers traveling at the same speed and help minimize the risk of getting seriously injured. The seat belts are produced from cloth with good flexibility. Therefore when the car crashes it gives the passenger or driver space and time to come to halt without bouncing in the car. The shoulder straps and lap belts help to restrain the passenger at the sturdy parts of the body.
Both seat belts and airbags increase the security and safety of the car. Therefore the composition of both airbag and seat belt is great lifesaver equipment in the car.
So whether you are driving in the city or on the high way and at whatever speed, wearing seat belts should be mandatory. Accidents can happen anytime and anywhere. These are not planned incidents; these are unfortunate accidents which can be made less painful and less severe with the help of seat belts and airbags.
