Loose Airbag

Anyone have a good idea on how to reattach this? Rear curtain airbag on an 09 access cab.
Thanks

 

Pry the cap off and get access to the screw head?

 

Yup, I was hesitant to pry it open, I don't know much about air bags. i disconnected the battery and pried it open, no problem.
Thanks

 

I believe it's just a bolt cover and not part of the airbag system. The label on the cap is just there to alert drivers, passengers and first responders to the fact that there are side airbags in that general region.

 

I've always wondered what was under there. I knew it wasn't the whole airbag but wasn't sure what exactly was under it. I've been tempted many times to pry it open and see, but always backed out because I had this strange fear of that thing going on randomly while driving.
