Abstract
The invention is directed to a prosthesis which includes first and second members pivotally coupled together and two links which are pivotally coupled together with one link being pivotally coupled to the first member and the other link being pivotally coupled the second member. A control mechanism is provided which is pivotally coupled to the first member and the pivotal connection of the two links to move the two links and hence the second member relative to the first member. The first member may be coupled to a person to allow the prosthesis to serve in one embodiment as an arm or as a portion of an arm and in another embodiment to serve as a leg or as a portion of a leg.

A prosthesis for a limb of a person, comprising:
- a first elongated member having first and second spaced apart ends,
- a second elongated member having first and second spaced apart ends,
- means for pivotally coupling said second end of said first member to said first end of said second member,
- a first link having first and second ends,
- means for pivotally coupling said first end of said first link to said first member,
- a second link having first and second ends,
- means for pivotally coupling said second end of said second link to said first end of said second member,
- link coupling means for pivotally coupling said second end of said first link to said first end of said second link,
- body coupling means for coupling said first end of said first member to a person, and
- power means for moving said first link to cause movement of said second link and hence movement of said second member.
