One of the rear seat belts in our car has become wrapped around the arm of a childrens booster seat and seems to have triggered the ratchet mechanism that prevents it from releasing more belt to loosen it. Giving the retraction mechanism some slack makes it just retract the belt a little more and locks everything even more tightly into place.
I've tried parking on a reasonably steep hill (facing up) and it still didn't release. The mechanism for the belt seems to be difficult to access within the body of the car; I can't see how I would get to it, though presumably there must be a way (though with the bulky kids car seat stuck in the way, there is a chance I won't be able to get to it because of that).
Short of disassembling the seat belt mechanism, however it might be done, does anyone have any other ideas how I might get the belt to release?
One idea I had was to get someone in the back and accelerate up a steep hill (which would have a stronger effect than simply being parked. Even if it is possible for this to work, I think the belt might need some slack given to it at the time (perhaps with someone sitting in the back), though I'm not sure how much. Each time it gets a little slack, it tightens more, so I won't be able to keep trying this!
Cutting the arm off the booster seat may work (not sure whether the seat will remain usable), though I'm worried the seat belt might get damaged in which case it would need replacing anyway.
Anyway, new ideas are appreciated! Thanks
