2. You could take it apart. There is a spring and a ball bearing which stops the lock. Be careful when you take it apart and see how it is put together, they are not he easiest things to put back together.
Caution - do not remove.......just make me more curious ;-)
I removed one from my subaru that had a clear cover so you could see how it works. The "lock" seems to be in the scuare looking thin beneath the springcase..... a dremmel maybe
Removed the side that didn't contain the sprring. There was this little le ver with a lead weight on it. First I thought it was some magnet that activate when ig ition was turned on but itwas in fact a weight that was operated with gravity
Well either you guys are nice people and didn't call me a idiot or rear seatbelt are just such a boring topic but at a first glance the two rear seatbeltsrollers look symetric but is actually not.
The little white bulge is what differ from the right and left.
