1. A joint brace for a joint orthesis, the joint brace comprising:
two articulated limbs pivotably mounted on each other in a central bearing arrangement,
wherein a head of a first articulated limb of the two articulated limbs supports the central bearing arrangement and the central bearing arrangement are connected by non-positive fit to a head of a second articulated limb of the two articulated limbs to form a pivot joint of the two articulated limbs,
wherein, on the central bearing arrangement, a sliding surface curved toward the head of the second articulated limb is formed, and the head of the second articulated limb has a curvature of matching shape, such that the head of the second articulated limb lies and is guided with positive fit in the curved sliding surface, and forms a tilting joint, wherein the second articulated limb is tiltable toward a pivot axis against the first articulated limb, wherein a tilt angle with respect to a primary pivoting plane of the tilting joint is from about −20° to about +20°,
wherein the head of the second articulated limb has a window for guiding a clamping block, which is configured to be clamped on the central bearing arrangement of the first articulated limb to fix the head of the second articulated limb by non-positive fit in the curved sliding surface, and the clamping block has clamping shoulders which engage behind a backside of the head of the second articulated limb to clamp the head of the second articulated limb on the central bearing arrangement of the first articulated limb, wherein the clamping shoulders have sections with at least one of lines, groves, or ridges which engage with a corresponding catch surface on a lower surface of the head of the second articulated limb, the at least one of lines, groves, or ridges are parallel to one another and extend longitudinally in each section,
wherein the central bearing arrangement on a base contains a profile disk, on which the curved sliding surface is formed,
wherein the profile disk has a slotted limb, and
wherein at least one limiting pin guided in recesses in the head of the first articulated limb engages, in order to form a pivot limitation.
