Toyota Yaris: How the SRS Air Bags Work / Curtain Air Bags

The curtain air bags are mounted in the front and rear window pillars, and the roof edge along both sides.

When the air bag crash sensors detect a side impact of greater than moderate force, the curtain air bag inflates quickly and helps to reduce injury mainly to the rear outboard passenger’s head caused by directly hitting interior parts such as a door or window.

For more details about air bag deployment, refer to “SRS Air Bag Deployment Criteria”.

In a side impact

Greater than moderate impact to one side of the vehicle will cause the curtain air bag on that side only to inflate.

Only one side curtain air bag will deploy on the side of the vehicle that receives the force of an impact.

In a roll-over

In response to a vehicle roll-over, both curtain air bags inflate.

Both curtain air bags will deploy after the roll-over accident is detected.
