         2 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that the structural base ( 1 ) comprises:
 a central platform ( 1   a );   a plurality of diagonal braces ( 1   b ) coming from the central platform ( 1   a ), and which free ends thereof connect with surrounding pieces ( 3 ); and   two inner braces ( 1   c ) coming from the central platform ( 1   a ) and which free ends thereof connect with angle brackets ( 7 ).   
     
     
         3 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that the surrounding pieces ( 3 ) comprise grooves ( 3   a ) through which the surrounding pieces connect with the C-shaped smaller inflatable sleeve ( 2 ), and with the flat structural base ( 1 ). 
     
     
         4 . Independent equipment for bedding straightening, according to  claim 2 , characterized in that the angle brackets comprise horizontal branches ( 7   a ) that comprise corresponding grooves ( 7   c ), through which the free ends of the inner braces ( 1   c ) are attached to the flat structural base ( 1 ). 
     
     
         5 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that the angle brackets ( 7 ) comprise two fastening devices ( 15 ) each comprising a winding extension ( 15   a ) coming from a vertical branch ( 7   b ) of the angle brackets ( 7 ) and a terminal head ( 15   b ), defining between the latter and the winding extension an intermediate space ( 15   c ) where bedding ( 5 ) back ends are introduced under pressure, this being associated to the larger inflatable sleeve ( 9 ); wherein a material elasticity of the fastening devices ( 15 ) provides the necessary tightening to hold bed clothes ( 5 ). 
     
     
         6 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that the angle brackets ( 7 ) comprise anchorage devices ( 16 ) arranged in line with a lower part of a vertical branch ( 7   b ) of such angle brackets ( 7 ), comprising an elbow flange that is hooked on the base ( 6 ) of the bed ( 5 ) through snap. 
     
     
         7 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that:
 the larger inflatable sleeve ( 9 ) comprises a rectangular frame-shaped structure;   a smaller back side of the larger inflatable sleeve ( 9 ) comprises a narrowing ( 9   a ) connecting from within with the distribution valve outlet ( 13 ); and   larger sides ( 9   b ) of the larger inflatable sleeve ( 9 ) progressively narrow toward ends connecting with a smaller side ( 9   c ) of such larger inflatable sleeve ( 9 ) corresponding to a head rest of the bed ( 5 ).   
     
     
         8 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that:
 the independent equipment further comprises a ventilation inflatable sleeve ( 8 ) arranged parallel to the C-shaped smaller inflatable sleeve ( 2 ), and it is associated with the bottom sheet ( 10 ) by means of terminal appendices ( 11 ) which release compressed air in a controlled manner to allow the bottom sheet ( 10 ) to be ventilated.   
     
     
         9 . Independent equipment for bedding straightening, according to  claim 1 , characterized in that the distribution valve ( 13 ) is attached at a center of the crosspiece ( 2   a ) of the C-shaped smaller inflatable sleeve ( 2 ).
