ABSTRACT OF THE DISCLOSURE The invention relates to a hinge intended to be used preferably in an orthosis and having the function of supporting, protecting and/or controlling a body joint, said hinge including at least two flexible, essentially strip shaped elements (1, 2) arranged mutually slidable in a plane- to-plane relationship, which elements (1, 2) are carried by supporting members (3, 4) having a controlling and guiding function, at least one of these strip shaped elements (1, 2) being a resilient strip element (13 of a high degree of springiness and of a high stiffness, which element is resiliently flexible in the longitudinal direction of the strip, about an axis located in the main plane of the strip essentially perpendicular to the longitudinal direction of the strip, but which is essentially rigid against bending about an axis essentially perpendicular to the main plane and longitudinal direction of the strip, the remaining strip elements (2) having a lower degree of springiness and a less stiffness than the resilient strip elements (1), to serve as spacer elements having the function of guiding and supporting the resilient strip elements (1) and having essentially the same longitudinal extension as the resilient elements (1) so that in flexing the hinge the spacing of the strip shaped elements (1, 2) is maintained constant along substantially the whole extension of the strip shaped elements (1, 2), and at least one of the strip shaped elements (1, 2), preferably at least one of the resilient strip elements (1), being directly or indirectly fixed at both ends, means being provided in order to allow the supporting members (3, 4) to move, when the hinge is flexed or extended, along curves which are defined mutually and relatively in dependence of the flexion and extension, which curves are determined by the hinge movement.
