Here’s the damage the side curtain airbag does to your headliner on a F10. This is all from just a small front bumper damage,,,she hit the front bumper right where the crash sensor is causing all the drivers airbags to deploy. This is the drivers knee bolster airbag. The drivers airbag only deployed the first stage,,,,because this as not a big accident,,,,I would have taken a picture of the bumper damage,,,,but you can not see the damage,,,she just pushed in the bumper and it popped right out,,,leaving no damage.
