A lumbar support device has a seat frame, a pair of brackets connected to opposite sided of the seat frame, a pair of flexible members connected to the pair of brackets in such a manner as to respectively form a pair of center sections across the seat frame, and an actuator assembly operatively connected to each one of the flexible members. Each one of the flexible members preferably has a pair of levers on opposite sides of the center sections that rotate about the brackets. In operation, the actuator assembly selectively bows the center portions of the flexible members. The actuator assembly preferably includes a reversible gear and a pair of bowden cables that move one pair of levers when the reversible gear is rotated clockwise and move the other pair of levers when the reversible gear is rotated counter-clockwise. |
