SRS Components: Airbags

The SRS is a supplemental safety device which, when used with the seat belt, is designed to help protect the driver and passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit, including the impact sensor (A), the cable reel (B), the driver's airbag (C), the front passenger's airbag (D), the side airbags (E), the side curtain airbags (F), the seat belt tensioners (G), the side impact sensors (first) (H), the front impact sensors (I), and the side impact sensors (second) (J).

Since the driver's and front passenger's airbags use the same sensors, both normally inflate at the same time. However, it is possible for only one airbag to inflate. This can occur when collision severity is near threshold for airbag deployment. In such case, the SRS will only deploy airbags when the protection provided by the seat belt is insufficient.
