Guide joint for a joint orthosis

A guide joint (1) for a joint orthosis (2) for supporting and guiding an anatomical joint (7), wherein the guide joint (1) has a first joint member (3) and a second joint member (4), and the joint members (3, 4) are connected to one another by a first linear guide (5) and a second linear guide (6), wherein each of the linear guides (5,6) has a guide track (10, 11) formed in the second joint member (4) as a slot or groove, in which in each case a sliding element (12, 13) arranged in the first joint member (3) engages, wherein the guide tracks (10, 11) intersect, the two sliding elements (12, 13) are spatially separate and spaced apart from one another and protrude from the first joint member (3), wherein the first sliding element (12) during the first 30° of the joint flexion does not substantially change its position in the guide track (10) due to the forced guidance of the sliding elements (12, 13) in the guide tracks (10, 11).
