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;
- and
- at 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.
