Abstract: A body support device to support at least one part of a body when lifting and/or carrying, having at least a first body fastening element fixable above a human's hip joint, at least a second body fastening element mechanically fixable below a human's hip joint and merely on the back side at least one elastic, which mechanically connects the first and the second body fastening element on the back side. The elastic is adapted to be tensioned when a person mechanically linked to the body support device is bending down and to apply an erecting force to the person when the person is bent down. A biasing device adjusts the length of the elastic between the respective fixations on the first body fastening element and the second body fastening element and has a pivotable mounted eccentric element adapted to apply a compressive force on the elastic and a counterpressure surface.
