Abstract:
A hip joint for connecting an artificial leg to a prosthesis mounting part, the hip joint comprising:an upper transverse link having on its upper side a connector for attachment to a prosthesis mounting part:a lower transverse link having on its underside a connector for releasable attachment to an artificial leg;a front link articulated at its upper section, via a first joint, to a front section of the upper transverse link and articulated at its lower section, via a third joint connection, to a front section of the lower transverse link, wherein the first and third joint connections together have at least five degrees of freedom;a rear link articulated at its upper section, via a second joint connection, to a rear section of the upper transverse link and at its lower section, via a fourth joint connection, to a rear section of the lower transverse link,wherein the second joint connection comprises a hinge pin having its pivot axis approximately perpendicular to the sagittal plane and has one degree of freedom, andwherein the fourth joint connection has a pivot axis with mediolateral and anteroposterior inclination with respect to the sagittal plane and has one degree of freedom, whereby a swiveling about the pivot axis of the second joint connection causes outward/inward swiveling and abduction/adduction of the lower transverse link; andan extension limit stop defining the starting position of the hip joint in extension.
