After looking at those pics, I had to see how the airbag is mounted.. From your pics, the welds broke on the brackets on the back if the air bag. Those two metal brackets are spot welded to the bottom of the bag and then its bolted to the dash thru those brackets. The deployment probably broke the welds and since the way it deploys it couldnt come out until the car was upside down. If it is a problem they will recall it. I wouldnt worry too much about it. It wouldnt be the first time I have seen airbag recalls from manufacturers.... I remember a few years ago one manufacturer had installed the curtain airbags backwards. I was glad to see a strong structure.
