Abstract:
An insulation cloth is provided having two or more layers on top of each other and connected to each other along connecting lines forming airways between them. Gas may be provided into between the connecting lines to provide for improved insulation of the cloth.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0005]    In the following description, various aspects of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the present invention. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details presented herein. Furthermore, well-known features may be omitted or simplified in order not to obscure the present invention.  
         [0006]    Reference is made now to FIGS. 1, 2 and  3 , which are schematic illustrations of a cloth fabric  10  fabricated according to embodiments of the present invention. Cloth fabric  10  may include more than one layer of cloth  50 . Said more than one layer of cloth  50  may have any desired property, such as flexibility, water repellant, breathablity, etc. Said more than one layer of cloth  50  may be connected by stitches  52  (or by any similar connecting means) to one another, and may also be sealed, so that the geometry defined between every two adjacent connection lines forms continuous passage (or airway)  14  in cloth fabric  10  (see FIG. 3). Airway  14  may have any type of geometry as long as it forms a continues airway passage. Airway  14  may have one or more inlet end  16 , and one or more interconnection  18  to other airways (not shown).  
         [0007]    Cloth fabric  10  may also comprise an integral pump  20  connected, either fixedly or removably, to cloth fabric  10  so that its outlet is in active connection with inlet end(s)  16  of airway  14 . Pump  20  may be powered by a mobile power source such as, but not limited to, a battery or to a stationary power source.  
         [0008]    Pump  20  may be used for pumping in (inflating) or pumping out (disinflation) various types of gases (such as air, oxygen etc.) or fluids (such as water, oil etc.).  
         [0009]    Cloth fabric  20  may be used for various purposes, such as:  
         [0010]    Protection,  
         [0011]    Insulation,  
         [0012]    Heat preservation/assertion,  
         [0013]    Medical treatment, etc.  
         [0014]    Pump  10  may be controlled by an ECU (Electronic Control Unit) that is a part of the pump or is an external device, so as to provide various profiles of inflation/disinflation as function of time. Such inflation/disinflation profiles may be a continuous (ramp) inflation and disinflation, pulsed inflation/disinflation, random inflation/disinflation, etc.  
         [0015]    Cloth fabric  20  may have any desired precut form and dimensions, and may also include specifically designed open interconnection  18 , made so as to fitly be connectable to an adjacent cloth fabric  10  thus allowing for the formation of multi patch fabric, constructed of plurality of cloth fabric  10  connected to each other, all being pumped by only one pump  20 .  
         [0016]    In another embodiment of the present invention a multi patch fabric may consist of plurality of cloth fabric  10  connected to each other so that each such cloth fabric  10  is being pumped by it&#39;s own, dedicated, pump  20 .  
         [0017]    Cloth fabric  10  may change its dimension or shape when being pumped as a result of the inflation/disinflation.  
         [0018]    While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
