Inflatable safety apparatus

1. An inflatable safety apparatus ( 10 , 10 ′) which is manually or automatically operated, comprising:

(a) a ribbon-shaped case ( 13 , 26 ) forming a belt and consisting of a strip of at least partly elastic or elasticized material folded onto itself along its larger sides, said ribbon-shaped case having opposing ends and being provided with connection means for said opposing ends;

(b) a substantially circular section tubular inflatable chamber ( 12 ) having the shape of an open ring with opposing free ends tightly sealed and faced in the opposite direction on the front side of the user's body along the abdominal area;

(c) at least one open ring lifebuoy-shaped inflatable element ( 15 , 18 ) having opposing ends and a section slightly higher than that of the inflatable chamber ( 12 );

(d) flexible extensible ducts ( 14 , 14 ′, 16 , 16 ′, 27 , 60 ) each connected and communicating at a first end, with the inflatable element ( 15 , 18 ) and, at an opposite second end, with the tubular inflatable chamber ( 12 ), the extension of said ducts allowing the positioning of said inflatable element ( 15 , 18 ) at the height of the user's armpit;

(e) at least one pressurized gas bottle ( 17 , 20 ) operatively communicating with inflatable chamber ( 12 ) or said inflatable element ( 15 , 18 ) and provided with a valve assembly ( 32 ) and an operation rod ( 25 , 54 );

said tubular inflatable chamber ( 12 ), inflatable, element ( 15 , 18 ) and flexible ducts each being folded onto itself and together with said at least one pressurized gas bottle being housed in said ribbon-shaped case ( 13 , 26 ).

2. The inflatable safety apparatus as defined in claim 1 , wherein said gas bottle operatively communicates with one of the opposing free ends of said tubular inflatable chamber.

3. The inflatable safety apparatus as defined in claim 1 , wherein said gas bottle is housed in said inflatable element.

4. The safety apparatus as defined in claim 1 , wherein said ribbon-shaped case ( 13 , 26 ) is made of fabric or natural and/or synthetic material and it is provided with a buckle ( 30 ) or two complementary components ( 19 , 21 ) integral to the opposing ends of said case and elastically engaging between them.

5. The inflatable safety apparatus as defined in claim 4 , wherein said inflatable element ( 15 , 18 ) is provided with a buckle or fastening adjusting means ( 19 ′, 21 ′) secured to the opposing ends of said inflatable element.

6. The inflatable safety apparatus as defined in claim 1 , wherein said ribbon-shaped case ( 13 , 26 ) is provided with removable fastening means ( 23 , 28 ) placed along one or more parts of the edge and/or of the surface of the same ribbon-shaped case.

7. The inflatable safety apparatus as defined in claim 6 , wherein the removable fastening means are hook and loop fasteners arranged in strips ( 23 ).

8. The inflatable safety apparatus as defined in claim 1 , wherein said ribbonshaped case ( 13 , 26 ) is at least partly elastic or elasticized and is integrated into a bathing trunk.

9. The inflatable safety apparatus as defined in claim 1 , wherein said compressed gas bottle ( 17 , 20 ) is fastened by heat sealing and/or adhesive collars ( 58 ) or valve supports ( 17 ′) to at least one of said inflatable element ( 15 , 18 ) or said tubular inflatable chamber ( 12 ).

10. The inflatable safety apparatus as defined in claim 1 , wherein a ribbon or tape ( 27 , 60 ) is associated to one or more flexible extensible ducts ( 14 , 14 ′, 16 , 16 ′) connecting the inflatable element ( 15 , 18 ) to the tubular inflatable chamber ( 12 ).

11. The inflatable safety apparatus as defined in claim 10 , wherein the ribbon or tape ( 27 , 60 ) is fastened at its opposing free ends respectively to the tubular inflatable chamber ( 12 ) and to the inflatable element ( 18 ).

12. The inflatable safety apparatus as defined in claim 1 , wherein the tubular inflatable chamber ( 12 ) is fastened at one or more points to the ribbon-shaped case ( 13 , 26 ) by adhesives, heat sealing or other fastening means.

13. The inflatable safety apparatus as defined in claim 1 , wherein said at least one compressed gas bottle ( 17 , 20 ) is of the automatic operation type.

14. The inflatable safety apparatus as defined in claim 1 , wherein said inflatable element ( 15 , 18 ) is provided with a projecting mouthpiece ( 35 ) with a removable closing cap ( 37 ).
