Air Bag: Description and Operation

CONSTRUCTION AND FUNCTION





The SRS airbag consists of an airbag control module, electric sensor and safety sensor built into the control module, and airbag modules of driver and passenger containing an inflator and airbag. Electric sensor and safety sensor are connected in series, so that the airbag will inflate if electric sensor and safety sensor sense an impact at the same time.





The SRS airbag is provided as an auxiliary driver and passenger front seat restraint system to be used in combination with the seat belt. When an impact greater than a set level is applied to the front of the vehicle, the sensor senses it and generates an electrical pulse to inflate the bag in the airbag module, thus preventing the upper bodies of the driver and passenger in the front seat from impacting the steering wheel, instrument pane and windshield.





AIRBAG MODULE
The driver's airbag module is located at the center of the steering wheel, and passenger's airbag module is located at upper side of instrument panel, and it each contains an airbag and inflator. If a collision occurs, the inflator produces a large volume of gas inflating the nylon airbag in a very short time.

AIRBAG CONNECTOR
The SRS airbag adopts a connector which has a double lock mechanism and coupling error detection mechanism for enhanced reliability. If coupling is incomplete, the airbag warning light comes on in the combination meter.
