Bed to chair mechanism

As it turned out what I wanted to achieve wasn’t actually that difficult. Once I figured out the principle it was actually pretty simple, I even made a working lego model.

Unfortunately I only have one photo of it. (see attached) v=zacyCORD_0I


I’ve also attached a side view of a CAD model I made of the mechanism, unfortunately I cant really show any more as its for a client.

Another company are already using the same method, YouTube?
