This concept isn't unique by itself. Examples are far and few between but some exist, mainly as thought experiments and proofs of concept. My main inspiration comes from Paul Elkins and his pedal camper experiment.

Basically he did a lot of the grunt work in measuring and testing. At the end he encourages people to take the design further so that is what I want to do. I took his sketches, applied them to my body size and available materials and came up with a rough skeleton on which I would build my version.

Then slowly I translated this into this:

My first change was to permanently extend the back for light storage like sleeping bags and a small cooler, this is pretty much is based on the original geometry and although through the iterative design process I have a lot has changed and a lot of the techniques will be different, the basic geometry will not change a lot.
