Pedestrian airbag technology a production system pdf. And they work because of chemistry, with some physics thrown in. Since the early stages of development, airbag technology has been undergoing continual evolution in terms of design. Working of bag type fabric filters in pneumatic conveying systems handling fine or dusty material, the method of filtration that has become almost universally adopted is a bag type fabric filter. In 1980s, first commercial airbags appeared in the automobiles. The chemistry behind airbags department of chemistry. An airbag is an automotive safety restraint system for an occupant as well as. A test procedure for airbags report 8328 european commission.
The goal of any supplemental restraint system is to help stop the passenger while doing as little damage to him or her as possible. First, electromagnetic valve opened immediately after receive the signal. To begin, an explanation is given of the principle of. Working of air bags air bags are designed to inflate in frontal or frontalangle impacts in which the car strikes an immovable object at more than about 16 kilometers per hour or another car at twice that speed. After a collision, sensors sense an electric current to an igniter system or, in some cases, to the computerized control unit. When a car crashes, the force required to stop an object is very great because the cars momentum has changed instantly while the passengers has not there is not much time to work with. At that time, a major obstacle was the time available for the airbag to inflate.
