The two load-side longitudinal beams (4) define a sliding plane, and on the two narrow sides of the back-pack frame (1) there is at least one holding element (6) for a shackle (7) that protrudes beyond the load-side longitudinal beams (4). On each carrier-side longitudinal beam (3) above the lowest element (6), there is at least one side-wall element (9) that is of flexible material. Side-wall elements (9) that are opposite each other on the two carrier-side longitudinal beams (3) are configured so as to be joinable to form a covering on either the load side or the carrier side. It is preferred that a slide plate (5) be arranged between the load-side longitudinal beams (4), the load-side longitudinal beams forming edge runners in the slide plate (5).
