Claim:
A lumbar belt back support apparatus for supporting the spine and para-lumbar musculature at the small of the wearer's back in a lordosis position while the wearer is seated, said support comprising; an elongated, circumferentially rigid extending belt portion having a pair of opposed belt ends adapted to be releasably placed about the person's waist, said belt portion having an inner surface and an outer surface; a compartment centrally located on the outer surface of the belt portion and positioned to be centrally adjacent the wearer's lower back when the opposed belt ends are connected, said compartment being configured to contain an inflatable bladder; a substantially oval inflatable bladder having a length, height and thickness dimensions provided inside said compartment, said length dimension of said bladder being positioned in a horizontal direction within the compartment; pump means for adjustably, manually inflating and deflating said bladder; tubing means for connecting said pump means with said bladder; wherein said bladder is configured to expand outwardly from said outer surface of said belt portion when manually inflated such that said bladder expansion causes compression between the wearer's back and the back of a chair or seat, causing pressure on the lower spine and back of the wearer; and wherein said bladder is configured as a hemi-elliptical shape such that more pressure is exerted on the lower spine than the surrounding para-lumbar musculature.
