Abstract
The invention relates to a swivel connection between two parts of an orthopedic technical aid, for example a prosthesis or orthotic device, with an adjustable, inherent articulation stability, consisting of a plane kinematic articulation chain with at least four articulation members and a polycentric swiveling characteristic composed of translatory and rotatory components, the swiveling of at least one articulation member being limited in at least one swivel direction by a first swivel stop. For improving the function, it is proposed that at least one articulation member should be designed in such a way that its length can be altered under the action of an external force.
