Modern detailed Equipotential Space Suit. Features original patent drawings from the original document but with a modern take. 

This invention relates generally to a full pressure suit and relates more particularly to the combination of a pressurized space suit with a plurality of joint assist mechanisms disposed exterior of the suit and at each movable joint to assist in joint movement by the suit occupant and performing in a manner that the joint being moved or bent and all its components remain in a state of near-neutral equilibrium regardless of the angle of bend of the joint. The expression near-neutral equilibrium is used instead of neutral equilibrium to indicate that the system is real and therefore contains some friction
