I looked up the only brand of fold down tables I know and apparently they started already in 1981, so it makes sense the product was well established half a decade later. Parallel invention happens, it is not a complicated invention, but it is just as likely someone remembered something they saw abroad. We don't know. But apparently they executed well on the idea, regardless of where it came from.
