Air bag light

[Exahiyan]

I flipped down my back seats to put my dog's crate in and used ratchet straps to secure it. As soon as I started the truck to move down the driveway, the airbag light came on and stayed on. After I removed the crate, the light went off. I didn't know that the back seats had airbag sensors in them. Do they?

May have been pinching the front seat with the headrest or the way the front seat was moved...
