Sacroiliac belt and composite structure

Abstract

A sacroiliac belt with a non-elastic inner belt to wrap around the user's hips and an elastic outer belt to wrap from the back to opposite sides of the inner belt. Non-cinchable hook and loop fastener construction is used to secure the inner and outer belts in position. The inner belt includes an inside urethane foam layer with open-cell frictional gripping surface, a non-elastic outside layer of loop material, and a hook tab for engaging the loop material to close the belt. The inner belt may be established with a non-elastic composite foam-fabric structure comprising a bi-laminate of the foam and elastic fabric, and a strip of loop material secured lengthwise onto the fabric side of the bi-laminate. The outer belt includes an elastic strip and hook tabs for connecting to the strip of loop material. The non-elastic composite foam-fabric may be used in other orthopedic braces and supports.

 a) a first layer of elastomeric, urethane based composition foam with an open-cell frictional gripping surface and positive moisture wicking characteristic;    b) a second layer of stretchable fabric secured to the foam layer and extending the length and width thereof;    c) a strip of lengthwise non-stretchable loop material of hook and loop fastener construction secured to the second layer, opposite the first layer, along the length thereof; and    d) a hook tab of hook and loop fastener construction secured proximate one end of the strip of loop material.

       3 . The composite band as defined in  claim 1  in which the hook tabs are positioned for connecting to the strip of loop material in a non-cinchable fastening arrangement.  
   
   
       4 . The composite band as defined in  claim 1  in which the first and second layers extends widthwise beyond the strip of loop material to establish a lengthwise cushion over the edges of the strip of loop material.  
   
   
       5 . The composite band as defined in  claim 1  further comprising a ring secured proximate the end of the strip of loop material opposite the hook tab, and in which the hook tab is sized to be slipped through the ring and secured to the strip of loop material.

 ii) an outer layer of loop material extending in secured relation with the inside layer for encircling placement around the user's hips, and  
 iii) a hook tab at one end thereof in fastening engageable relation with the loop material with the inner belt encircling the user's hips; and  
   b) an elastic outer belt sized to extend forwardly from the back of the inner belt to the sides thereof, the outer belt having hook tabs for connecting to the loop material of the inner belt.    
   
   
       10 . The sacroiliac belt as defined in  claim 9  in which the outer layer of loop material is lengthwise non-elastic loop fabric secured to and extending the length and width of the inside layer of foam.  
   
   
       11 . The sacroiliac belt as defined in  claim 9  in which the hook tabs are positioned for connecting to the strip of loop material in a non-cinchable fastening arrangement.  
   
   
       12 . The sacroiliac belt as defined in  claim 9  further comprising stretchable fabric secured to and extending the length and width of the foam layer, the outer layer of loop material being lengthwise non-elastic and secured to the stretchable fabric along the length thereof, the stretchable fabric and foam layer extending widthwise beyond the edges of the outer layer of loop material.  
   
   
       13 . The sacroiliac belt as defined in  claim 12  in which the stretchable fabric is unbroken loop fabric having loop size substantially smaller than the loop of the outer layer of loop material.  
   
   
       14 . The sacroiliac belt as defined in  claim 9  in which the hook tabs are positioned for connecting to the outer layer of loop material in a non-cinchable fastening arrangement.  
   
   
       15 . A sacroiliac belt comprising: 
 a) a non-elastic inner belt configured for encircling placement around a user's hips, the inner belt having
