What is happening here? Are those bolts tight and the belts can't swivel?
Couple of observations, I can't see your car from here but based on this picture.....
I think the harness bar is backwards. What you have as the front should be the rear. That would allow the belts to point up from the bracket and wrap over the top of the bar to the seat. As it is now, if you ever needed those shoulder harnesses, the seat belt loops themselves are just going to fold up.
If mounted the way I described they would be loaded in tension.
