Abstract: A carrier frame is for a back load having an extended resilient element that extends in a closed loop and crosses itself in such a way that it forms a shoulder element, an anchor element and a hip element between the crossings. Segments of the element can be moved in relation to each other. The shoulder element has a shoulder fastening for shoulder straps, the anchor element is adapted for support of the back load, and the hip element has a hip fastening for a hip belt. The load is resiliently suspended in the carrier frame, which gives possibility of damping. The back load may be a pack bag in a rucksack, a child seat or another pack.
