Abstract
The invention relates to a prosthetic device (), in particular a foot prosthesis, for fitting leg amputees, with a universal joint mechanism (), which couples a shaft () with a treading attachment () through an articulation, wherein the universal joint mechanism () comprises a joint element () supported such that it is rotatable about a first rotational axis (C) and a second rotational axis (D) differing therefrom. For more accurate modeling of the natural gait of a healthy human foot, the invention provides that the universal joint mechanism () comprises a shaft-side joint fork () coupleable with the shaft () and a treading-side joint fork () coupled via the joint element () through an articulation with the shaft-side joint fork (), wherein the shaft-side joint fork () is swivellable about the first rotational axis (C) and the treading-side joint fork () about the second rotational axis (D) relative to the joint element (), and wherein the swivel movements of shaft-side and treading-side joint fork () relative to the joint element () are carried out against the resistance of at least one damping element () proximal to the joint element.
