Airbags in cars has been proven to reduce traffic deaths for drivers and passengers in current years, and today similar safeguards might be extended facing outward of vehicles, diminishing the blow for cyclists and pedestrians hit by cars.

Swedish manufacturers allow us an airbag to inflate underneath the car's bonnet, reduced the effect on any riders who land onto it. One more, at the support of the windscreen, stop a cyclist's head going by means of the glass.

The bags are triggered when sensors detect that an individual is heading for the automobile right after being hit.

"In Europe each and every year far more than 10,000 pedestrians and other vulnerable road users are killed in a collision having a vehicle," Times Online quoted.

Mats Odman, a spokesman for Autoliv, the Swedish manufacturer which has developed the airbags, as saying. "Most of these hit their scalp about the windshield or the hood," Odman added.

The new airbag is an advance on existing safety features including "pop-up" bonnets, which stop injuries by rising up slightly when they're hit, keeping the victim's head away from the engine.

The Air Bag normally includes the following 3 parts:

The bag is made of a thin, nylon fabric that is folded into the controls or dashboard or, more recently, the seat or door.

The sensor will be the device that informs the bag to blow up. Inflation happens when there's a smash force comparable to running into a brick wall at Ten to fifteen miles per hour (16 to 24 km each hour). Sensors detect the crash using a mechanical switch that closes whenever a mass shifts as well as an electrical contact is created. Electronic sensors make use of a tiny accelerometer that has been etched on a silicon chip.

The environment bag's inflation program uses the rapid pulse of hot nitrogen gas in the chemical reaction of sodium azide (nan3) and potassium nitrate (kno3) to inflate the bag.
