Multiple chamber foam air mattress

Abstract

The present invention comprises a fluid pressurizable multiple chamber mattress wherein one or more chambers is capable of operably receiving and releasing a fluid. The mattress has a first and/or a second fluid pressurizable chamber, which may include material, defined between the outer surfaces of the fabric layers.

1 . A fluid pressurizable multiple chamber mattress comprising: 
 a first covering sheet having an inner surface and an outer surface;    at least two fabric layers wherein at least one layer is positioned upon the inner surface of the first covering sheet, the fabric layers having an outer surface and an inner surface, the inner surfaces of the fabric layers being linked via a plurality of threads, the outer surfaces of the fabric layers carrying a fluid impermeable coating, wherein at least one coated outer fabric surface is in at least partial contact with the inner surface of the first covering sheet;    a second covering sheet having an inner surface and an outer surface, the second covering sheet positioned onto the first covering sheet and the fabric layers, wherein at least one coated outer fabric surface is in at least partial contact with the inner surface of the second covering sheet, wherein the inner surfaces of the first and second covering sheets contact beyond a perimeter of the fabric layers;    a first bond, whereby bonding the inner surfaces of the first and second covering sheets to the outer surfaces of the fabric layers forms a first and a second fluid impermeable fluid pressurizable chamber defined between the outer surfaces of the fabric layers and the inner surfaces of the first and second covering sheets;    a second bond, whereby bonding the inner surfaces of the first and second covering sheets forms a third fluid impermeable fluid pressurizable chamber defined between the inner surfaces of the first and second covering sheets and the inner surfaces of the fabric layers;    at least one fluid valve carried by at least one covering sheet for permitting the pressurization and depressurization of at least one fluid pressurizable chamber; and    a material inserted into at least one of the chambers defined between the outer surfaces of the fabric layers and the inner surfaces of the first and second covering sheets.    
     
     
         2 . The fluid pressurizable mattress of  claim 1 , wherein at least a portion of at least one of the first and second bonds is not completely sealed.  
     
     
         3 . A fluid pressurizable multiple chamber mattress comprising: 
 a first covering sheet having an inner surface and an outer surface;    at least two fabric layers wherein at least one layer is positioned upon the inner surface of the first covering sheet, the fabric layers having an outer surface and an inner surface, the inner surfaces of the fabric layers being linked via a plurality of beams, the outer surfaces of the fabric layers carrying a fluid impermeable coating, wherein at least one coated outer fabric surface is in at least partial contact with the inner surface of the first covering sheet;    a second covering sheet having an inner surface and an outer surface, the second covering sheet positioned onto the first covering sheet and the fabric layers, wherein at least one coated outer fabric surface is in at least partial contact with the inner surface of the second covering sheet, wherein the inner surfaces of the first and second covering sheets contact beyond a perimeter of the fabric layers;    a first bond, whereby bonding the inner surfaces of the first and second covering sheets to the outer surfaces of the fabric layers forms a first and a second fluid impermeable fluid pressurizable chamber defined between the outer surfaces of the fabric layers and the inner surfaces of the first and second covering sheets;    a second bond, whereby bonding the inner surfaces of the first and second covering sheets forms a third fluid impermeable fluid pressurizable chamber defined between the inner surfaces of the first and second covering sheets and the inner surfaces of the fabric layers; and    a material inserted into at least one of the chambers defined between the outer surfaces of the fabric layers and the inner surfaces of the first and second covering sheets.    
     
     
         4 . The fluid pressurizable mattress of  claim 3 , wherein at least a portion of at least one of the first and second dielectric welds is not completely sealed.
