Stuck rear seatbelt

[Dave Priebe]

I went out this morning to put a car seat in my avant, and found that
one of the rear seat belts is stuck. It is fully retracted, put will not
spool out at all. It feels locked, like when it is jerked quickly.
Unlike the newer Audis (my S6 for example), these belts aren't supposed
to lock like this, only when jerked quickly. I tried moving where the
car was parked, from flat to an incline in hopes that would release it,
but no luck. So I tried folding down the seat, and all that did was real
in more belt, so now I can't get the seat back up. Anyone have any ideas
of how to fix this?
Thanks,
