Patent attributes
A lumbar device located inside the back of a chair that tilts back and forth as a user shifts his weight in the chair. The lumbar stimulation device includes sets of back massaging rollers to apply a focused pressure and improve the circulation of blood flowing through the lower back of the user. The lumbar stimulation device is attached to a flexible strap that extends substantially vertically inside the chair had. One end of the flexible strap is affixed to the chair base below the chair seat. The opposite end of the strap is bent backwards when the chair back tilts backwards. When the user leans back, the back of the chair will be pushed downwardly with respect to the strap and the lumbar stimulation device attached to the strap to make it appear to the user that the back massaging rollers of the lumbar stimulation device are moving upwardly along his back.
