A power disc style seat reclining mechanism for a vehicle seat includes a seat base fixed mounted guide disc pivotally connected to a set of pivotal discs. The pivotal discs include an internal disc segment and a seat back attaching member. Within the internal disc is a connection features and linkage that may be actuated by a center shaft that is driven by a motor. When the internal disc is rotated, the desired seat back position is the end result as the motion is discontinued.

1. A seat reclining mechanism comprising: a seat base mounted disc adapted to be attached to a seat base;a seat back mounted disc adapted to be attached to a seat back;at least one elongated base mounted disc slot formed in the seat base mounted disc;at least one back mounted disc receiving hole formed in the seat back mounted disc;an internal disc sandwiched between the seat back mounted disc and the seat base mounted disc, the internal disc having at least one elongated internal disc slot formed in the internal disc; andat least one link including a body, a load bearing pin and an adjustment pin, wherein the load-bearing pin and the adjustment pin are positioned offset from each other and extend in opposite axial directions and wherein the load-bearing pin engages the at least one receiving hole of the back mounted disc, and the adjustment pin extends in an opposite direction from the load-bearing pin and passes through the at least one elongated slot of the internal disc and engages the seat base mounted disc through the at least one base mounted disc slot;wherein rotation of the internal disc causes the back mounted disc to rotate relative to the base mounted disc by sliding the at least one adjustment pin of the link along the at least one base mounted disc slot. 2. The seat reclining mechanism of claim 1, wherein the at least one elongated base mounted disc slot includes three elongated base mounted disc slots, the at least one back mounted disc receiving hole includes three back mounted disc receiving holes, the at least one elongated internal disc slot includes three elongated internal disc slots and the at least one link includes three links, wherein each slot and hole are formed on a corresponding disc, are spaced apart radially with respect to a center hole formed on the corresponding disc, and are spaced equidistant from adjacent holes or slots. 3. The seat reclining mechanism of claim 1, further comprising a central shaft attached to the internal disc, the central shaft passing through the seat base mounted disc and the seat back mounted disc. 4. The seat reclining mechanism of claim 3, wherein the central shaft is adapted to be driven by a motor to adjust the position of the seat back. 5. The seat reclining mechanism of claim 3, wherein the at least one base mounted disc slot is an arcuate slot positioned around a central opening. 6. The seat reclining mechanism of claim 5, wherein the at least one internal disc slot comprises a plurality of internal disc slots positioned equidistant from each other around the central shaft and are elongated perpendicular to the central shaft. 7. The seat reclining mechanism of claim 6, wherein the at least one back mounted disc receiving hole comprises a plurality of back mounted disc receiving holes spaced apart equidistant from each other around a central opening for receiving the central shaft. 8. The seat reclining mechanism of claim 1, wherein the body of the link forms a shoulder around the load-bearing pin and the adjustment pin and the shoulder is adapted to retain each pin in position. 9. The seat reclining mechanism of claim 1, wherein the body of the link is elongated and parallel with a plane defined by the seat back mounted disc and the load-bearing pin and the adjustment pin extend perpendicular with respect to the body. 10. The seat reclining mechanism of claim 1, further comprising a circular ridge on the seat base mounting disc, the circular ridge adapted to house the internal disc therewithin. 11. A seat reclining mechanism comprising: a seat base mounted disc adapted to be attached to a seat base;a seat back mounted disc adapted to be attached to a seat back;at least one elongated base mounted disc slot formed in the seat base mounted disc;at least one back mounted disc receiving hole formed in the seat back mounted disc;an internal disc sandwiched between the seat back mounted disc and the seat base mounted disc, the internal disc having at least one elongated internal disc slot formed in the internal disc;at least one link including a body, a load bearing pin and an adjustment pin, wherein the load-bearing pin and the adjustment pin each extend in an opposite direction wherein the load-bearing pin engages the at least one receiving hole of the back mounted disc, and the adjustment pin extends in the opposite direction from the load-bearing pin, passes through the at least one elongated slot of the internal disc and engages the seat base mounted disc through the at least one base mounted disc slot;a central shaft attached to the internal disc, the central shaft passing through the seat base mounted disc and the seat back mounted disc, andwherein the base mounted disc slot, the internal disc slot and the back mounted disc receiving hole align over movement of the seat back from an upright to a reclining position, whereby rotation of the internal disc causes the back mounted disc to rotate relative to the base mounted disc by sliding the adjustment pin of the link along the slot. 12. The seat reclining mechanism of claim 11, wherein the body of the link forms a shoulder around the load-bearing pin and the adjustment pin and the shoulder is adapted to retain each pin in position; and wherein the central shaft is adapted to be driven by a motor to adjust the position of the seat back. 13. A seat reclining mechanism comprising: a seat base mounted disc adapted to be attached to a seat base, the seat base mounted disc having at least one seat base connection feature;a seat back mounted disc adapted to be attached to a seat back, the seat back mounted disc having at least one seat back connection feature;an internal disc sandwiched between the seat back mounted disc and the seat base mounted disc, the internal disc having at least one elongated internal disc slot formed in the internal disc; andat least a link including a body and a pair of pins positioned offset from each other and extending in opposite axial directions, wherein at least one of the pins engages the at least one seat back connection feature and the other engages the at least one seat base connection feature and one of the pins passes through the elongated internal disc slot;wherein rotation of the internal disc causes the back mounted disc to rotate relative to the base mounted disc through the connection of the links with the connection features of the back mounted disc and the base mounted disc. 14. The seat reclining mechanism of claim 13, wherein one of the pair of pins is a load-bearing pin and the other is an adjustment pin. 15. The seat reclining mechanism of claim 14, wherein the load bearing pin engages the connection feature of the seat back mounted disc and the adjustment pin engages the seat base mounted disc and passes through the elongated internal disc slot. 16. The seat reclining mechanism of claim 14, wherein the seat base connection feature is an elongated slot for receiving the adjustment pin and the seat back connection feature is a receiving hole for receiving the load-bearing pin. 17. The seat reclining mechanism of claim 13, wherein the at least one seat base connection feature comprise a plurality of seat base connection features, the at least one seat back connection feature comprises a plurality of seat back connection features, the at least one elongated internal disc slot comprises a plurality of elongated internal disc slots, and the at least a link comprises a plurality of links, wherein each connection feature and slot are formed on a corresponding disc, are spaced apart radially with respect to a center hole formed on the corresponding disc, and are spaced equidistant from adjacent connection features or slots, and wherein each link connects corresponding connection features and passes through the corresponding elongated internal disc slot. 18. The seat reclining mechanism of claim 17, wherein the plurality of seat back connection features, plurality of seat base connection features, plurality of elongated internal disc slots and plurality of links include three seat back connection features, three seat base connection features, three elongated internal disc slots, and three links. 19.
