Seatbelt question.(not auto problem)

[Tiamat-red]

I have a 92 LS-L with the automatic seatbelts. My question is: are the "recoilers" supposed to lock? Meaning I can pull the belts in and out and they will not stop. They don't seem to want to keep me in the seat.
All 4 of them.
The owners manual says they are supposed to "allow free movement inside the car unless you plow into something". Or whatever...
But I've done some pretty hard stops to see if they will lock up, and they won't.
In my previous cars(not Subaru) they seemed to be centrificaly(sp) locked. When you yanked on them hard they would lock.
But not my SVX's.
Is my car a rolling deathtrap?
Or are they working properly.

P.S. it was in a frontal collision sometime before I bought it, and the airbag also doesn't work. So I at least want the seatbelts to!
Maybe I should just get a 4 point harness and let my passengers worry about themselves.
