<p>A rucksack has a pair of shoulder straps mounted on the upper regions (4) of its rear wall (2) and a hip belt mounted on the lower regions (6) of its rear wall (2), an extensible intermediate region (10) being provided between said upper and lower regions (4,8) and movable between a compacted position and an extended position whereby the upper regions (4) and the attached shoulder straps can be moved towards and away from the lower regions (8) and the attached hip belt. Releasable locking means (14,16) are provided which, for any given position of the intermediate region (10) between its compacted position and its extended position, can be actuated to retain the intermediate region (10) in that position and thereby secure the upper and lower regions (4,8) relative to one another. <IMAGE></p> |
