The Development Tendency of Airbag

The airbag is one of the high quality products about the safety system in car. Compared with the seat belt, the airbag is a type of subsidiary protection equipment. The device is consisted of gas generator, control system and airbag. The control system of this device is composed of transducer, electric control system and trigger device.

The airbag improves the safety of automotion dramatically. According to the recent data, the accidental death rate was decreasing by twelve percent since the wide utilization of the device; moreover, the injury severity was also lightened. However, the device may hurt people badly sometimes. The airbag is designed according to the normal setting posture and the ideal ignition moment, however, there are many elements that influence the effect of the device, which include the height and weight of the driver, the magnitude of collision.

There are two tendencies of the airbag for the time being. The automotive manufactures in America and Japan are trying to increase the size of the airbag to protect the passengers, while some European manufactures maintain that the airbag is not the key to do protection, it will play a role only in a monolithic safety system. In this system, the tighten seat belt, construction reliable seat, seats for babies and other components must be installed. It is better to consider the installation of the components in the safety system at the beginning of the construction design.

For the warning safety system, the airbag is the main component currently. The airbag is controlled by a warning transducer, and can unfold before the collision to buffer the collision power better. The warning safe system improves the protective effect of the seat belt and airbag, and can predict the potential danger to adjust itself.

The development of further gasbag includes the advanced transducer and information processing technology. These components are able to provide some reliable collision information within little time. The information includes the magnitude and form of collision, the figure and seating posture of the passenger. The related integrated circuit about microwave oven is IL329T.
