location of seat, side curtain airbags

[Traveler999]

Can anyone tell or show me from where the side airbags deploy from the side of the seats? I would like to put on temporary seat covers and would like to create an appropriate sized opening in the proper location to allow airbag deployment. I've looked at the seats and it almost looks like the stitches in the seat material would have to break since I couldn't find any obvious seam opening. If you bought custom seat covers that accomodate this please post or send me a pic. Thanks for any help.
