A back support belt comprising a primary support belt including fasteners for fastening the same generally at the frontal area of the waist of the wearer, and a secondary tensioning belt comprising fasteners for fastening the same around the primary support belt generally at the frontal area of the waist of the wearer is provided, and includes back support belt color tensioning indicators on the secondary tensioning belt which are visible only from the rear and side areas of the waist of the wearer, and thus not by the wearer, and which are operable to indicate both when the back support belt is properly tensioned around the waist of the wearer, and when the back support belt is not properly tensioned around the waist of the wearer. The back support belt color tensioning indicators are operable to indicate proper and improper tensioning of the support belt independently of the relationship between the size of the support belt and the waist size of the wearer to thus be virtually foolproof in operation. For use in instances wherein the wearer of the back support belt is forced to work in the absence of anyone qualified to observe the color tensioning indicators on the secondary tensioning belt, the back support belt will further include an additional color tensioning indicator taking the form of non-obscurable alignment marks formed on one of the primary support belt fasteners and co-operable with one of the secondary tensioning belt fasteners to indicate proper back support belt tensioning. The additional color tensioning indicator is not, however, operable independently of the relationship between the size of the support belt and the waist size of the wearer, and are thus not foolproof in operation.
In a back support belt comprising a primary support belt including fastening means for fastening the primary support belt generally around the waist of the wearer, and a secondary tensioning belt including fastening means for fastening the secondary tensioning belt around said primary support belt generally around the waist of the wearer to tension said back support belt, the improvements comprising, said secondary tensioning belt including readily visible back support belt tensioning indicator means distinct and remote from said secondary tensioning belt fastening means for indicating the tensioning of said back support belt, said back support belt tensioning indicator means being readily visible generally at the rear area of the waist of the wearer.
In a method for indicating the tensioning of a back support belt which comprises a primary support belt including fastening means for fastening the primary support belt generally around the waist of the wearer, and a secondary tensioning belt including fastening means for fastening said secondary tensioning belt around said primary support belt generally around the waist of the wearer to tension said back support belt, the improvements comprising, the steps of, indicating the tensioning of said back support belt by providing readily visible back support belt tensioning indicator means on said secondary tensioning belt distinct and remote from said secondary belt fastening means, and disposing said back support belt tensioning indicator means on said secondary tensioning belt so that the same are readily visible generally at the rear area of the waist of the wearer.
