A backpack attachment is provided for use with backpacks that have a bag-like body and a pair of shoulder straps, in particular backpacks used by school attendants, which is effective to distribute the backpack weight in a rationalized fashion across a user's shoulders. The attachment comprises essentially two curved members (1) arranged to stiffen substantially the sections of the shoulder straps (T= that lie closest to the upper region of the bag-like body (CS). These members may replace or be associated with said sections of the shoulder straps (T), and consist of a pair of substantially inflexible curved members being each a one-piece construction (2, 2A), or consist of several pieces (6, 11) jointed to one another. In a preferred embodiment, the attachment comprises a pair of members formed each of several pieces (11) which can be associated detachably to the shoulder straps (T), at least one (14) of them in a locked fashion.
