Abstract
The invention relates to a hip joint which has an attachment for an artificial leg and which, in order to permit a largely natural walking movement, has the following features: a front link (,) and a rear link (,) are articulated at their respective upper sections, via a first joint connection (,) and a second joint connection (,), respectively, to a front section and a rear section, respectively, of an upper transverse link (,), and are articulated at their respective lower sections, via a third joint connection (,) and a fourth joint connection (,), respectively, to a front section and a rear section, respectively, of a lower transverse link (,); the first and third joint connections (,) together have at least five degrees of freedom; the second joint connection (,) is a hinge pin which with its pivot axis (,) is approximately perpendicular to the sagittal plane and has one degree of freedom; the fourth joint connection (,) has a pivot axis (,) with mediolateral and anteroposterior inclination and with one degree of freedom, so that a swiveling about the pivot axis (,) of the second joint connection (,) causes outward/inward swiveling and abduction/adduction of the lower transverse link (,).
