Air Bag Systems: Description and Operation

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: SYSTEM DIAGRAM


















SYSTEM DESCRIPTION

1. GENERAL

(a) G sensors used for the airbag system are installed on various parts of the vehicle and calculate the deceleration rate of each part during a collision.

(b) Depending on the situation, the center airbag sensor assembly sends a deployment signal to each airbag based on the information from each sensor.

2. DEPLOYMENT CONDITION

(a) FRONTAL COLLISION





(1) Frontal collision signals are produced based on the information from the center airbag sensor assembly and front airbag sensors.

HINT
*: In case of a frontal collision, the ignition signal could be output with the deceleration sensor on signal even without a signal from the front airbag sensor.

(2) Frontal collision signals are used to deploy all the airbags except the side airbags.

(b) SIDE COLLISION (1)





(1) The side airbags are deployed based on signals from the side airbag sensors and center airbag sensor assembly.

HINT
The curtain shield airbags and front seat outer belts are deployed at the same time.

(c) SIDE COLLISION (2)





(1) The curtain shield airbags are deployed when both of the following conditions are met:

* Signals from the door side airbag sensors, side airbag sensors or rear airbag sensors are received.

* A signal from the center airbag sensor assembly is received.
