It is definately inside the seat back.
The hole in the top is only as wide as
the seat belt webbing.
There is no way anyone could get their
hand in there.
I have looked at the bottom of the seat
back,there is no access.
If I pull the seat belt with my ear to
the seat back I can hear the mechanism
clicking,the sound is about half way down.
Thanks anyway,I'II wait and see if I get
any more replies then its hole cutting time!
