The invention relates to a recliner-type orthosis comprising a lap belt or pelvic strap (30), a rigid recliner rail (10) over the spinal column, and two individually tightenable shoulder straps (23, 24), each of which extends from a lower portion (12) of then recliner rail (10), forms a shoulder strap, and is guided backwards via guides (18, 19) on a top portion (14) of the recliner rail (10), where the two shoulder straps (23, 24) intersect in a central point of intersection (29) and then run contralaterally towards the front, intersect in lateral points of intersection (27, 28) and can finally be tightly attached to the lap belt (30).
