ABSTRACT:
The invention relates to a prosthetic device (30), in particular a foot prosthesis, for fitting leg amputees, with a universal joint mechanism (32), which couples a shaft (34) with a treading attachment (40, 42) through an articulation, wherein the universal joint mechanism (32) comprises a joint element (44) 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 (32) comprises a shaft-side joint fork (36) coupleable with the shaft (34) and a treading-side joint fork (38) coupled via the joint element (44) through an articulation with the shaft-side joint fork (36), wherein the shaft-side joint fork (36) is swivellable about the first rotational axis (C) and the treading-side joint fork (38) about the second rotational axis (D) relative to the joint element (44), and wherein the swivel movements of shaft-side and treading-side joint fork (36, 38) relative to the joint element (44) are carried out against the resistance of at least one damping element (90, 92) proximal to the joint element.
