Short video I took while repairing stuck seatbelt to show how this mechanism works.
This repair was of course just a temporary solution. I do not recommend repairing seat belts! Buy new or used (but 100% working) instead. It's the most important safety feature of your car. Do not underestimate it.
Recorded using Sony Xperia S, couldn't get better focus (I don't have a tripod for my phone).
