Advanced, complicated folding-type hinges? Answered
I'm working on converting a panel van into a perfect, optimal full-time living space. It needs a permanent bed which I want to make use of the otherwise wasted cab area (since I won't be driving and sleeping at the same time). When driving, I want it flat against the ceiling and to sleep I want it to fold down between the dash and the back of the seats - a cutout for the top if the steering wheel is fine.
This involves moving it through a very specific path through space with a mechanism along the same lines as the folding rotation of a sofa bed. I would like to know what joints are available so that I can figure out the correct combination for the required movement but I can't even find the names of them. "Complex hinges" doesn't seem to bring up anything useful. Any suggestions?
