Problem with seat belts

[fury78]

I have bought a 2001 Tahoe and the third row seemed not to be used never, so I installed the bench seats but when I tried to unfold the seat belt keeps locked and does not allow me to open the seat, I can only put the backrest up to 45º in one of the bench because the belt is blocked. The other bench can be put in the upper position but the belt is so tense that is not posible to use or move.

Any idea, diagram or suggestion ?. How is posible to remove the belt ?

Thanks in advance

Is the belt clicked in? If so unclick it... then pull it all the way out and release it back to resting position. Dont click them in before folding.

The problem is that is not posible to pull it out, seems to be blocked.
