There are many vehicles that may look different but in fact, are the same vehicle with just a different exterior appearance. A good example is the Suburban and the Tahoe. Same vehicle, built on the exact same assembly line, but different in their exterior trims, certain features, and the length of the vehicle. Tahoe=short, Suburban=a long Tahoe.
The same similarities exist with the Escalade; a General Motors series of very similar vehicles. I recently compared the roof airbag systems of an Escalade EXT, which is an overpriced pickup truck and an Escalade ESV, which is a high-end,expensive SUV.
Engineering diagrams provided by GM show that on the pickup truck version, because the cab is short, the roofline is not very long. The roof airbag stored gas inflator is one the C-pillar.
On the SUV version of an Escalade, the roofline is longer. For this vehicle, GM mounts the roof airbag stored gas inflator horizontally along the roof rail.
Images follow that illustrate inflator positioning for the 'sister' vehicles. One more reason vehicle rescue crews should be stripping the trim to inspect the exact area where they are going to make a cut anytime you are working to cut into any part of a roof structure.

The airbag engineering diagram for the Escalade Esv, which is GM's high-end version of the Tahoe or Suburban
Look closely and you will see how the stored gas inflator is mounted horizontally along the roof rail.

Now, look at the interior headliner area of an Escalade EXT; their expensive version of the Avalanche which is an expensive version of a pickup truck.
With this vehicle, the roof airbag system had to have a curve put into the airbag gas fill tubing. The stored gas inflator is mounted vertically on the C-pillar.
To take the picture, I am in the rear seat, behind the front passenger. You are looking at the inside of the driver's side C-pillar with the headliner and trim removed.

Here is the engineering specs for the roof airbag system on the shorter vehicle; the Escalade EXT model. Very similar except very different! Important differences that all rescuers should remember when getting ready to cut a roof. Strip the trim every time, every place you cut.

Here they both are as they appear in real life...

If you have close look at the ESV grahpic, you will also notice that there is a 2nd inflator for the rear curtain airbag in the D-post of the vehicle.
This setup can be found on a number of vehicles, especially long ones. It is possible to fill a curtain airbag with two inflators or to seperate curtain airbags for certain seat rows.Jorg Heck
