How to fix a stuck rear seat belt in a Mecedes suv m class

SOURCE: Volvo V70 rear seatbelt jammed

you can remove the bolt that holds the seatbelt to the floor by pulling off the seatpad where the belt goes to the floor and then raise the seat and the belt should reset. this happens on my passenger side rear seat.

Got it, with the help and eyes of my wife. The rear latch releases as the seat back is lowered. This release is ALMOST seat back down (about 3 inches above the seat bottom). As the seat back lowers, apply constant lift on the rear latch, and it will release as the seat back lowers. Hard-won knowledge - I think I invented some bad words in the process.

I have the passenger side seat belt which on occassion will lock in the retacted position It has done this twice but I was able to realease the belt moving the strap around. Now nothing I do will release the strap. Is there a mechanical problem I can look at or could there be an electricial issue
