The position adjustment device comprises two position control and adjustment means which enable the position of the haversack to be adjust relative to the harness. The first means allows the haversack to be raised and the second means for it to be lowered. The first means comprises an inelastic traction cable (5) with its first end (5a) located in the bottom part of the haversack and its other end (5b) having a gripping loop (5c). There is a return means (6) fixed in the harness bottom median part allowing the passage of the cable. The cable is retained by elastic tension strands (8) located between the cable parts to form a coil. The second means comprises an endless belt (9) connected to a clevis (10). |
