Inflatable member for a protection device for a ship hull

Abstract

An inflatable member for a protection device for the hull of a ship, characterized in that the inflatable member includes a deformable casing ( 1 B) housed in a textile flexible pocket ( 1 D) unattached to the casing ( 1 B), the flexible pocket ( 1 D) limiting the deformation extent of the deformable casing

1 . An inflatable member for a protection device for the hull of a ship, comprising:
 a deformable casing housed in a textile flexible pocket unattached to the casing, the flexible pocket constructed to limit a deformation extent of the deformable casing.   
     
     
         2 . An inflatable member according to  claim 1 , comprising:
 a flexible hollow central body provided with perforations which allow air to pass, said flexible hollow central body being surrounded by the deformable casing and connected to a supply duct.   
     
     
         3 . An inflatable member according to  claim 2 , further comprising:
 an air supply/discharge duct of the inflatable member constructed to cause movement of said inflatable member.   
     
     
         4 . An inflatable member according to  claim 3 , wherein the air supply/discharge duct comprises a flexible metal casing. 
     
     
         5 . An inflatable member according to  claim 1 , further comprising a weight at a free end of the inflatable member. 
     
     
         6 . An inflatable member according to  claim 1 , wherein the inflatable member has an elongated shape. 
     
     
         7 . An inflatable member according to  claim 2 , wherein the inflatable member of the protection device is connected to the air supply/discharge duct by a coupling which is adapted to allow rotation of the inflatable member relative to the air supply/discharge duct. 
     
     
         8 . An inflatable member according to  claim 1 , wherein the textile flexible pocket is made of weaved nylon.
