1. A seatback comprising a pair of frame members, an upper back support comprising a tubular member pivotally attached to the pair of frame members, a support surface comprising a substantially rigid planar base attached to the tubular member, and a latch operably coupling a first end of the tubular member to a frame member to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position. 2. The seatback of claim 1, wherein a central portion of the tubular member forms a substantially U-shaped and upwardly extending configuration within a plane of the seatback when in the stowed position and the substantially rigid planar base is attached to the central portion of the tubular member. 3. The seatback of claim 2, wherein the seatback further comprises a head restraint having an exposed surface and a cushion disposed above the upper back support to form a movable exposed surface, and the exposed surface of the head restraint and the movable exposed surface of the upper back support form a substantially continuous plane when the upper back support surface is in the raised position. 4. The seatback claim 3, wherein the upper back support further comprises a foam pad and the movable exposed surface of the upper back support further comprises a resilient trim material disposed about the foam pad to maintain a flat surface and eliminate wrinkling between the stowed position and the fully raised position. 5. The seatback of claim 2, wherein the substantially rigid planar base further comprises a raised support proximate an upper edge of the substantially rigid planar base and disposed beneath the cushion. 6. The seatback of claim 2, wherein the upper back support is disposed centrally between a first and second lateral edge of the seatback and below the head restraint. 7. The seatback of claim 1, wherein the stowed position is about 0° relative a plane of the seatback and the raised position is about 15° relative the plane of the seatback. 8. The seatback of claim 7, wherein the plurality of positions of the upper back support comprises intervals of 1.5° between the stowed position and the fully raised position. 9. The seatback of claim 1, wherein the latch comprises a ratchet gear and ratchet pawl operably coupled with the ratchet gear and wherein displacement of the upper back support beyond the fully raised position actuates the ratchet pawl to an over travel condition to return the ratchet latch and the upper back support to the stowed position. 10. The seatback of claim 1, wherein the upper back support is controlled manually by pulling the upper back support forward relative the seatback. 11. The seatback of claim 10, wherein the upper back support is moved from the stowed position to one of the plurality of positions by manually pulling the upper back support. 12. The seatback of claim 11, wherein the upper back support further comprises a pull strap by which the upper back support is pulled forward relative the seatback. 13. The seatback of claim 12, wherein the upper back support is pulled forward in increments of 1.5° between the stowed position and the fully raised position. 14. A seating assembly for a motor vehicle comprising: a seatback pivotable between an upright position and a fully reclined position operably coupled with a lower seating structure, the seatback further comprising a frame having an upper transverse cross member, a lower transverse cross member, and a pair of opposed lateral seatback frame members extending between the upper and lower transverse members, wherein each of the pair of opposed lateral seatback frame members has a seatback pivot mount at a lower portion thereof that is operably coupled with the lower seat pivot mount; andan upper back support comprising a tubular member pivotally attached at a first end to one of the pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form an exposed surface. 15. The seating assembly of claim 14, further comprising a lower back support disposed below the upper back support, the lower back support being operably coupled with the upper back support and raised relative an exposed surface of the seatback when the upper back support is raised from the stowed position. 16. The seating assembly of claim 14, wherein a central portion of the tubular member forms a substantially U-shaped configuration within the plane of the seatback when in the stowed position, the substantially rigid planar base is attached to the central portion of the tubular member, and the latch comprises a ratchet gear and ratchet pawl operably coupled with the ratchet gear. 17. The seating assembly of claim 16, wherein displacement of the upper back support beyond the fully raised position actuates the ratchet pawl to an over travel condition to return the ratchet latch and upper back support to the stowed position. 18. A seating assembly for a motor vehicle comprising an upper back support comprising a substantially U-shaped tubular member pivotally attached at a first end to one of a pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form a movable exposed surface. 19. The seating assembly of claim 18, wherein the seatback further comprises a head restraint having an exposed surface and the exposed surface of the head restraint and the movable exposed surface of the upper back support form a substantially continuous plane when the upper back support surface is in the fully raised position.
