The seat back frame is mounted on a pair of rotatably mounted shafts to allow the seat back to assume two opposing seat positions. A pair of link members are operatively connected to the pair of shafts and pivotally attached to the seat cushion frame, and have cam surfaces to engage a cam follower. Pins on the link members contact link members for support of one link member in each of the two seat positions.
