Life jacket resistant to separation from wearer caused by buoyancy thereof

Abstract

A life jacket includes a jacket body having a neck and two armholes. At least one fastening strap is mounted to an outside surface of the jacket for tightening the jacket on a wearer. An anti-sliding strip made of a resilient material having a high friction with respect to the wearer's skin is mounted to an inside surface of the jacket at a position substantially corresponding to the wearer's waist. By tightening the fastening strap, the anti-sliding strip is forced to contact and thus forming a high friction and tight engagement with the wearer's skin to prevent the jacket from sliding movement with respect to the wearer thereby eliminating separation of the jacket from the wearer caused by buoyancy of the jacket.

What is claimed is:  
     
         1 . A life jacket comprising: 
 a jacket body having armholes;    a fastening strap mounted to the jacket body; and    an anti-sliding strip mounted an inside surface of the jacket body for engaging a wearer's skin, the strip being made of a material having a high friction with respect to the wearer's skin whereby by tightening the fastening strap, the anti-sliding strip is forced to engage the wearer's skin, forming a high friction engagement therebetween for preventing a sliding movement of the jacket body with respect to the wearer.    
     
     
         2 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip is mounted at a location substantially corresponding to the wearer's waist.  
     
     
         3 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip is formed by screen printing on the inside surface of the jacket body.  
     
     
         4 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip has a surface pattern.  
     
     
         5 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip is additionally mounted to the inside surface of the jacket body.  
     
     
         6 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip has a corrugated cross section.  
     
     
         7 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip has a plane cross section.  
     
     
         8 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip is sewn to the inside surface of the jacket body.  
     
     
         9 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip forms an interior chamber.  
     
     
         10 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip forms an interior chamber having opposite ends sealed.  
     
     
         11 . The life jacket as claimed in  claim 1 , wherein the anti-sliding strip forms an interior space having opposite open ends.
