Heat retaining wetsuit

Abstract

A wetsuit comprised of two layers of laminated rubber sponge material which may or may not be fabric coated. A stuffing material of variable thickness is located in selected areas between the two rubber sponges referred to herein as Air Chambers. The two layers of laminated rubber sponges are glued together along their adjacent surfaces except in selected areas where their common borders of the sponges are left unglued and form a watertight construction, i.e., the “Air Chamber”. The stuffing material is a light material with a density of 0.02˜0.05 mg/cm 3 and typically formed of multi-layered fiber structure and the like. The Air Chamber can be located at any part of the wetsuit to provide the person who wears the wetsuit the function of heat retaining/thermal insulation and impact protection. In an additional embodiment, the stuffing material is secured within another thin plastic enclosure within the air chamber. This enclosure may be provided as a single pocket or as a plurality of contiguous pockets.

1 . A wetsuit fabric comprising at least two layers of a sponge-like material selected areas of which are glued together and at least one other area of which is left unglued to form an enclosed chamber therebetween, said chamber being filled with a stuffing material separating the two adjacent layers of sponge-like material.  
   
   
       2 . The wetsuit fabric of  claim 1  wherein said stuffing material has a density in the range of 0.02˜0.05 mg/cm 3 .  
   
   
       3 . The wetsuit fabric of  claim 1  where said sponge-like material layers each has a fabric surface.  
   
   
       4 . The wetsuit fabric of  claim 1  wherein said stuffing material is in the form of a layered fabric.  
   
   
       5 . The wetsuit fabric of  claim 1  wherein said stuffing material is further enclosed within at least one pocket of thin plastic material within said chamber.  
   
   
       6 . The wetsuit fabric of  claim 1  wherein said stuffing material is further enclosed within a plurality of contiguous pockets of thin plastic material within said chamber.  
   
   
       7 . A wetsuit comprising at least two layers of a sponge-like material selected areas of which are glued together and at least one other area of which is left unglued to form an enclosed chamber therebetween, said chamber being filled with a stuffing material separating the two adjacent layers of sponge-like material.  
   
   
       8 . The wetsuit of  claim 7  wherein said stuffing material has a density in the range of 0.02˜0.05 mg/cm 3 .  
   
   
       9 . The wetsuit of  claim 7  where said sponge-like material layers each has a fabric surface.  
   
   
       10 . The wetsuit of  claim 7  wherein said stuffing material is in the form of a layered fabric.  
   
   
       11 . The wetsuit recited in  claim 7  wherein said at least one other area is along the chest region of said wetsuit.  
   
   
       12 . The wetsuit recited in  claim 7  wherein said at least one other area is along the back area of said wetsuit.  
   
   
       13 . The wetsuit of  claim 7  wherein said stuffing material is further enclosed within at least one pocket of thin plastic material within said chamber.  
   
   
       14 . The wetsuit of  claim 7  wherein said stuffing material is further enclosed within a plurality of contiguous pockets of thin plastic material within said chamber.
