Abstract:
A lumbar support device, comprising:a first flexible member comprising a first pair of levers and a first center section between said first pair of levers; a second flexible member comprising a second pair of levers and a second center section between said second pair of levers; and an actuator assembly comprising a first operative connection to said first flexible member through said first pair of levers and comprising a second operative connection to said second flexible member through said second pair of levers, wherein said actuator assembly moves said first pair of levers to bow said first center section and wherein said actuator assembly moves said second pair of levers to bow said second center section, wherein said actuator further comprises a gear, said gear being movable in a first direction and in a second direction to move said first pair of levers and to move said second pair of levers, respectively, and wherein said first center section is adjusted to a first partial-curvature through said first operative connection as said gear is continued to be moved in said second direction until said second center section is adjusted to a second full-curvature, and wherein said second center section is adjusted to a second partial-curvature through said second operative connection as said near is continued to be moved in said first direction until said first center section is adjusted to a first full-curvature.
