Abstract

The invention relates to a join mechanism of a knee orthosis or knee prosthesis, having a first part (14), a second part (15), which is pivotable relative to the latter, and attachment means (2) for securing the joint mechanism (1) to a user of the knee orthosis or knee prosthesis, and having a locking mechanism (4, 40) with which a pivoting of the two parts (14, 15) relative to each other in a flexion direction is prevented by a form-fit element 94) which is arranged movably on the second part (15) and which, in the locking state, engages with a form lit in a recess (40) assigned to the first part (14), wherein the form-fit element (4) is mounted rotatably on the second part (15) and has a contour which, in the locked position, protrudes into the recess (40) and, in the released position, allows the first part (14) to pivot past the bearing of the form-fit element (4).

Dependent claims

A joint mechanism of a knee orthosis or knee prosthesis having a first part and a second part, which is pivotable in relation thereto, and a connector for fastening the joint mechanism on a user of the knee orthosis or knee prosthesis, as well as having a locking mechanism, by way of which a pivoting of the two parts relative to one another in the direction of flexion is prevented with a positive locking element, which is arranged so as to be displaceable on the second part and, in a locking position, engages in a positive locking manner in a recess associated with the first part, the positive locking element being mounted so as to be rotatable on the second part and has a contour which, in the locking position, projects into the recess and in a release position enables the first part to pivot past the positive locking element.
