A rucksack (10) having a rear panel or back (14) with a number of expansible sectors (16), (16'), (18), (18'), (20), (20'), (22), (24) of various shapes, located at the cervical, dorsal and lumbar regions of the user, inflated with air by means of a built-in device (32), and which provide for closely adapting the rucksack (10) to the anatomy of the user. A supporting belt, consisting of opposite branches (28), (28') extending from the bottom of the rear panel (14), incorporates a pad (30) designed to rest on the abdominal region of the subject and which provides for a counterthrust for relieving the longitudinal load on the spine. |
