I know this thread is OLD, but I attempted to remove my reclining rear seat back, and could NOT seem to get it out...How is it fastened??

To remove the lower cushion, I removed the two bolts at the front corners (where tabs would be on a non-reclining seat) slid it forward about an inch, and it just lifted right out. As for the seat back, I removed the two bolts at the bottom that mount it to the motor and track, but the seat still wouldn't come out. What am I missing? Seems like it's hung up on the vertical tracks...I tried lifting straight up, but it just stops and won't go any higher. Is there some sort of hidden release that I don't know about? This was with the seat in the fully reclined position, btw.
