I was minding my own business, driving down the street and I heard a SPROING. It felt like it was in the seat. I hit the back of the seat with my hand to feel around for the springs, and sure enough one of them was flapping loose.
I unzipped the right side of the seat cover, and one of the mounting brackets for the springs had snapped in half.
See this pic of the bottom spring, which isn't broken. You can see the other spring above it out of place.
The bracket itself snapped in half, as you can see here.
My question is whether you all have any ideas to fix it. I could get somebody to weld the broken half of the bracket back on. Otherwise, I can't see any way to fix just that piece other than grind off the old bracket, find a new bracket, weld the whole new bracket in place, and reassemble like new. All that requires a lot of labor that I don't have the tools for. The other option is pick up a junkyard seat and rebuild or replace the seat.
This is a pretty bizarre repair, but I'm open to any (cheap) suggestions.
