Car safety is ensured by the security system, including seat belts and airbags.
It is dangerous for a children safer for children The seat belts in the car perform their function only when they are correctly used. Do we know how this is done?
Those who incorrectly places the belt on the body and regulate their tension (in cases where there is no automatic tensioners), can obtain significant injury.
To the seat belts in cars were really served its purpose, it is necessary to fasten both belt - lumbar and shoulder.
The likelihood of damage to the chest when the fastening only the diagonal shoulder belt increases three times than in the case of both belts. Use only the shoulder strap is more dangerous than in other cases.
Further improvement of security systems has led to the creation of the seatbelt tensioner, providing timely response to emergency deceleration of the vehicle, pulling the driver and passengers to the backs of the seats.
Now in new cars equipped with modern passive safety systems, which are constantly being upgraded and enhanced.
Airbags have gained popularity in the 80's, when Ford and General motors in the mid-80 s introduced the production models. Now air bags became standard equipment. In the cars of the mid 90's began to appear also side airbag.
Pneumopathy supplements the seatbelt by reducing the chance of a blow to the head and upper body of a passenger on any part of the car. They also reduce the risk of serious injury, distributing the force of impact on the body of the passenger.
As it is an integral part of the design of the car, then it cannot be installed on a machine not designed for this purpose. Front airbags should not deploy in a side impact, the blow on the back part or the overturn of the vehicle.
Due to the fact that airbags are deployed only once and then quickly deflate, they are useless during a subsequent collision.
Airbags a new generation revealed with less energy than before, but despite this, the passengers must be at least 25 inches from them, to avoid injury, the airbag in the event of a collision.
Air bags are effective only when the passenger is correctly fastened seat belts. Otherwise, they can even be dangerous.
Seat belts help reduce the risk of serious injury in many cases. They promote the proper location of the passenger in the seat to maximize the effectiveness of air bags, and protects seat passengers in first and subsequent collisions.
Thus, it is vital to wear, even in vehicles equipped with airbags.
