Claim 24:
25. An orthopedic device for supporting a back of a user, wherein the orthopedic device comprises
an upper body element;
a first upper leg element arrangeable on a left upper leg of the user;
a second upper leg element arrangeable on a right upper leg of the user;
a first joint between the upper body element and the first upper leg element and a second joint between the upper body element and the second upper leg element, wherein each joint provides a pivot axis about which the upper body element and each respective upper leg element are pivotable relative to each other;
a first passive actuator which is configured to apply a first force to the first upper leg element arrangeable on the left upper leg when a first angle between the first upper leg element and the upper body element is within a first predetermined angular range;
a second passive actuator which is configured to apply a second force to the first upper leg element arrangeable on the left upper leg when the first angle is within a second predetermined angular range that is different to the first predetermined angular range;
a third passive actuator which is configured to apply a third force to the second upper leg element arrangeable on the right upper leg when a second angle between the upper leg element and the upper body element is within a third predetermined angular range; and
a fourth passive actuator which is configured to apply a fourth force to the second upper leg element arrangeable on the right upper leg when the second angle is within a fourth predetermined angular range that is different to the third predetermined angular range;
wherein the first, second, third and fourth passive actuators apply their respective forces in a same direction to a respective first or second upper leg element and the upper body element.
