  • first upper adjustment means comprising right 85 and left blockers 86
  • the loops 87 and 88 form a band sewn transversely on the front part 411 or 412 of the shoulder straps 41 and 42.
  • the first adjustment means 85 and 86 may be blockers, as illustrated in the figures, a pushbutton or any other adjustment means making it possible to vary the length of the links 83, 84 between the first adjustment means and the rear wall 24.
  • First and second upper adjustment means 85 to 88 are respectively disposed on each of the shoulder straps 41, 42, at the shoulder of the user 10 or, alternatively, on the front portion 411, 412 of the shoulder strap 41, 42.
  • the link 83, 84 passes a first time by the blocker 85, 86, then connects the blocker to the lower end of the passer 81, 82 associated, thus forming the lower strand 832, 842, and is then inserted into the passing, then connects the upper end of the passer associated with the blocker, thus forming the upper strand 831, 841, then passes a second time of the blocker.
  • the two free ends of the link 83, 84 exit the blocker 85, 86.

  • This compression system incorporating loops 81, 82 is advantageous because it allows to distribute the compression force over the entire length of the passer. The load is therefore compressed more uniformly.
  • the link can slip in the loop, which allows a self-balancing of the tension in the link.
  • the tension may be identical in the upper strand 841 and in the lower strand 842.
  • the upper compression system may have no loops 81, 82 in which case the ends of the links are directly attached to a lateral edge of the rear wall 24.
  • Anchor points can be defined for this higher compression system. Each anchor point corresponds to a connection between a link 83, 84 and an element of the rear wall 24. An anchor point may therefore be an end 811, 821, 812, 722 of a passer 81, 82, as illustrated in the figures. An anchor point may also be the point of attachment of a link on the edge of the rear wall 24, as described in the alternative solution.
