Abstract:
1. A lanyard suspension system for a prosthetic limb, the prosthetic limb including a prosthetic limb socket component having an interior and an inner surface, the lanyard suspension system comprising: a lanyard cord adapted to extend from a distal end of a patient's residual limb, the lanyard cord having a substantially circular cross section; and a lanyard lock assembly sized and shaped to be seated within the interior of the prosthetic limb socket component, between the inner surface of the prosthetic limb socket component and the patient's residual limb, at a distal end of a patient's prosthetic limb socket component, the lanyard lock assembly including the locking mechanism utilizing at least one biased jaw provided completely within the lanyard lock base for engaging with the lanyard cord in the cord channel when the lanyard cord is pulled in the opposite direction in the active setting; and wherein the lanyard cord extends from the distal end of the patient's residual limb, through the inlet hole in the proximal surface of the lanyard lock base, through the lanyard cord channel of the lanyard lock base, through the outlet hole in one of the side surface and the distal surface of the lanyard lock base, through the feed hole of the cord retraction mechanism, and to the spool of the cord retraction mechanism.
