Personal flotation cocoon

Abstract

A personal anti-drowning system comprising a front fastening inflatable cocoon and inflating means: the inflatable cocoon being fabricated from a water and air resistant fabric such that at least part of the inflatable cocoon comprises air tight inflatable pockets at least on back of said suit and wherein when inflated and in water, said inflatable pockets support a person within the cocoon above the water, who can partially unfasten front fastening of the suit and sit up so that body below the waste is in said cocoon and torso, head and arms of the person protrude out of said suit.

1 . A personal anti-drowning system comprising a front fastening inflatable cocoon and inflating means: said inflatable cocoon being fabricated from a water and air resistant fabric such that at least part of said inflatable cocoon comprises air tight inflatable pockets at least on back of said suit and wherein when inflated and in water, said inflatable pockets support a person within the cocoon above the water, who can partially unfasten front fastening of the suit and sit up so that body below the waste is in said cocoon and torso, head and arms of the to person protrude out of said suit. 
   
   
       2 . The personal anti-drowning system of  claim 1 , wherein said inflatable cocoon separately encases distal body limbs, such that movement of arms and/or legs of person therein, causes corresponding movement of sleeves and/or leggings of the inflatable cocoon. 
   
   
       3 . The personal anti-drowning system of  claim 1 , wherein a person therein is able to walk relatively unhindered when the cocoon is not inflated. 
   
   
       4 . The personal anti-drowning system of  claim 1 , wherein a person therein is able to walk in said inflated cocoon. 
   
   
       5 . The personal anti-drowning system of  claim 1 , wherein said cocoon is closable by a zipper. 
   
   
       6 . The personal anti-drowning system of  claim 1 , wherein said cocoon includes a transparent canopy over face of person therein. 
   
   
       7 . The personal anti-drowning system of  claim 6 , wherein said transparent canopy is fabricated from a clear polymeric sheet. 
   
   
       8 . The personal anti-drowning system of  claim 6 , wherein said inflated cocoon includes a loop for coupling to other suits. 
   
   
       9 . The personal anti-drowning system of  claim 1 , wherein, due to gravity thereon, a person therein naturally assumes a face upward floating position. 
   
   
       10 . The personal anti-drowning system of  claim 1 , wherein said inflating means includes a blow tube for manual inflation of said airtight inflatable pockets thereby. 
   
   
       11 . The personal anti-drowning system of  claim 1 , wherein said inflating means includes a source of gas. 
   
   
       12 . The personal anti-drowning system of  claim 11 , wherein said source of gas is a compressed gas cylinder. 
   
   
       13 . The personal anti-drowning system of  claim 11 , wherein said source of gas is a dense chemical that reacts with water to release prodigious quantities of gas. 
   
   
       14 . The personal anti-drowning system of  claim 13 , wherein said dense chemical is selected from the list of solids and liquids.
