Head Curtain side-impact bags are mounted in the roof rails.

Side-Impact Thorax bags are front seat mounted.

Maybe I worded that wrong. The side-impact Thorax bag is mounted in the seat, so it would be best to not cover it.
Seems like I remember seeing a plastic panel on the side of the front seats that cover this bag. The car is my wife's, so I can not go out and look at it now.
