I noticed what looks like a air bag folded in the driver side a pillar. What trim blows out when inflated?

 

If you noticed the a pillar trim came off very easy. So I would think that the a pillar trim would be what is blown out during inflation. Also I noticed that the bottom of that trim was a little harder to get out than the top so maybe it blows the top out and it folds down laying on the dash during inflation.
Just my thoughts.
