Abstract: A shoulder strap for devices adapted to carry loads, particularly on the back of a user, has a side widening toward the sternal area of the user and an arched shape, the dimensions and shapes being designed so that in worn condition the side widening can rest on the thorax area, below the cervicothoracic imaginary line and above the breast, while the section extending downward beyond the side widening overlaps the side area of the thorax, the breast being positioned in the area next to a concave side edge that bypasses the breast. A buoyancy compensator for diving comprising equipped may be equipped with one or more shoulder straps as described.

Abstract: A buoyancy compensator jacket for scuba diving includes an inflatable and deflatable bladder; a backplate part, to which the bladder and elements fastening at least one breathing gas cylinder are attached; and at least one pair of shoulder straps for securing it to the torso of a user and at least one ventral securing strap or ventral closure of the jacket. The jacket further includes a sternal securing element composed of at least one sternal or chest strap, which has at least one costal connection element distinct from the pair of shoulder straps and connecting the sternal strap to the backplate part.
