Automatic Seat Belt

hey guys!! I heard bout this site from a friend.. I have a 91 Automatic Toyota Camry, Its been a champ, considering it has 190,000 miles on it.. I have a problem with the automatic seat belt, when i get in the car and start it ,the shoulder strap stays forward and doesnt move back at all!! I tried opening the door and shutting it harder but still nothing, for the past few months Ive noticed that when I open the door and bout to get out that the shoulder belt makes kinda like a grinding sound and does it til it stops from moving forward.. But now its just completly suck forward it wont move back at all!! Ive tried pressing on that black thing on the inside door that I guess signals theh belt that the door is shut but still nothing!! I have no idea whats wrong with it at all, can u guys please help me out!!

Thanks

Big Daddy

is there any sound from it? or nothing?

checking the fuses to the car might b a good idea.

or there may be a trigger switch that has gone bad
