Shoulder strap for supporting back loads, device for carrying back loads, and in particular buoyancy compensator, or the like

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.

Description

FIELD OF THE INVENTION[0001]The present invention refers to the field related to devices for carrying back loads, i.e. of the type provided with at least one tie element, so-called shoulder strap, intended to be hooked or to pass around a user's shoulder and thanks to which the weight of the load is distributed on at least one part of the torso and is held against the user's torso.[0002]In particular the invention refers to carrying devices for sports activities, such as backpacks or the like and, after a further specialization in progress, for equipment for underwater use, such as in particular backpack supports of breathing gas cylinders.[0003]The invention finds its preferred and advantageous application in the field of buoyancy compensator or stabilizers, commonly known also by the acronym G.A.V. or BCD (Buoyancy Control Device) or, by the English term, jacket.BACKGROUND OF THE INVENTION[0004]In general, carrying devices of backpack type or the like are provided with one or two ...

AI Technical Summary

Benefits of technology

[0010]According to one aspect, the present invention provides for a shoulder strap whose shape is improved in order to avoid unwelcome and / or harmful stresses on the user's body.

[0012]According to still another aspect, the present invention is directed to a back carrying device for underwater equipment and in particular for one or more respirable-gas cylinder that provides greater comfort and reduces the physiologically potentially harmful stresses on the user's body.

[0013]A further aspect of the present invention provides for a jacket of the buoyancy control type or stabilizer type, combined with a support for a back load consisting of at least one respirable-gas cylinder, the jacket improving the comfort and anatomical shape of the parts intended to offload the weight supported on the user's body, particularly of the shoulder straps.

[0043]According to another characteristic, a sternum strap removably connecting the shoulder straps to each other and preventing them from progressively spread out can be provided in the sternal area of the user, said sternum strap being equipped with attaching means to be attached to the side extensions of the two shoulder straps.

[0047]As will be evident also from the following description of some exemplary embodiments, the particular configuration of the shoulder straps and the use thereof in a carrying device and in particular in buoyancy compensator or stabilizer for underwater use, allows the pressure of the shoulder strap on the torso to be transferred to areas anatomically less sensitive and more resistant, effectively bypassing areas where there are soft tissues and / or glands and / or organs sensitive to touch or compression.

Problems solved by technology

If there are careless configurations and heavy loads, this compression not only can be annoying, but it can also cause pain and also have harmful effects on the mammary organs.
