repairing a seam on boat seat

[jlscjs]

I have a pontoon with a sun deck to lay on, on the end of the cushion it has came apart at the seam but there is no way to remove it and sew it. I was wondering if there is a glue or something on the market that I could put on the part of the seam that has come apart to keep it from ripping the stitches out any more. Thanks

is the threads what failed, or did the vinyl fail?
