WS, welcome...
There is either a small "loop" of a strap sticking out from the seatback right there by the door, or a plastic lever up by the headrest area (depending on the seat model) These are the seat-tipping releases that are accessible from the front. There is also a release lever at the bottom/back near the backseat passengers feet (so they can flip it up to get out).
No stupid questions here... Jeeps aren't like any other vehicle, so expect many things to be "unique". That includes zippers, latches, plastic strips in metal channels, etc!
Ask away.
