MY18 206 R-Line wagon rear seat pic please?

[Wynnston]

In the pic above, see how there is a white metal bit showing above the buckles? I want to see what covers that, because i think something is missing there...

thanks!

I don't think you're missing it. I think it's been jammed/tucked into either side and instead the fabric should wrap around the metal part. Most likely the right part folds around it.
