Work suit having lifesaving function

Abstract

A work suit having a lifesaving function is provided where the work suit is made of two or more sheets of fabric, at least one variable contact tube keeping air in an amount smaller than a maximum capacity is formed in the uppermost part of a side of the work suit that corresponds to the girth of the body of a wearer, and when the variable contact tube gets into water, air in a lower portion is moved up by water pressure such that the thickness of an upper portion changes to the thickness when the variable contact tube is fully filled with air, so the variable contact tube come is in close contact with the body of the wearer.

What is claimed is: 
     
         1 . A work suit having a lifesaving function, wherein the work suit is made of two or more sheets of fabric,
 at least one variable contact tube keeping air in an amount smaller than a maximum capacity is formed in the uppermost part of a side of the work suit that corresponds to the girth of the body of a wearer, and   when the variable contact tube gets into water, air in a lower portion is moved up by water pressure such that the thickness of an upper portion changes to the thickness when the variable contact tube is fully filled with air, so the variable contact tube come is in close contact with the body of the wearer.   
     
     
         2 . The work suit of  claim 1 , wherein the variable contact tube is formed in a thickness that allows to come in close contact with the body of the wearer when the variable contact tube is fully filled with air. 
     
     
         3 . The work suit of  claim 1 , wherein the variable contact tube is formed in a height sufficient to allow air in the lower portion to move up to the upper portion and the upper portion to be filled with air corresponding to the maximum capacity.
