Seatbelt rattle

Anyone figured out a fix for a seatbelt that is not in use rattling incessantly up against the plastic of the door pillars? Other than buckling the strap when not in use, which is annoying for anyone getting in and out of the vehicle. The rattle drives me nuts.

 

Mine does it and the last 3 GMC trucks I had did it too. It’s because when your passenger takes it off, it doesn’t return to the original position flat to the pillar because the side bolster on the seat keeps it twisted sideways on the edge of the seat. If you reach over and push it back to its normal position, it’ll stop.
