The invention relates to a tiltable joint brace for a joint orthesis, comprising: two articulated limbs pivotably mounted on each other in a bearing arrangement, wherein the head of the first articulated limb supports a bearing arrangement which can be connected to the head of the second articulated limb by non-positive and positive fit in order to form the pivot joint. A curved sliding surface is formed on the bearing arrangement, and the head rests on the curved sliding surface with positive fit. There, the second articulated limb can tilt freely toward the pivot axis of the joint brace against the first articulated limb.
