Patent attributes
A portable, inflatable lumbar belt cushion for providing support to the lower spine and surrounding paralumbar musculature of the wearer while seated. The present invention is for an inflatable belt cushion which adjustably reinforces the small of the back to support the lower spine in a proper lorsdosis, alleviating lower back pain caused by improper posture and fatigue. The belt encircles the wearer's waist and contains a compartment with an inflatable cushion centrally located in the back of the belt which is superimposeable in the small of the wearer's back. The inflatable cushion is of a hemi-elliptical design which is positioned horizontally in the small of the back such that the thicker center portion of the cushion supports the spine and the thinner end portions support the surrounding musculature. The cushion extends outwardly from the outer surface of the belt and thus does not create a compression between the belt and the spine. Support is provided only when the wearer is seated and the cushion creates pressure between the wearer and the back of a chair. The cushion is inflated by manual means such that the firmness and pressure of the cushion is totally adjustable.
