<p>A self adjusting eccentric pivot mechanism is disclosed in a seat back recliner assembly (10) which eliminates backlash between the gears of the recliner mechanism to prevent vibration and rattle of a seat back when the seat is unoccupied. The self adjusting pivot includes a pivot pin (48) with an eccentric member (66) rotatable thereon upon which one gear of the recliner mechanism (10) is mounted. A biasing spring (52) rotates the eccentric member (66) to move the gears toward one another such that back lash between the gear teeth is eliminated. The use of a biasing (52) spring provides a self adjusting feature which enables the position of the eccentric member (66) to move as the seat back is adjusted over its range of motion to accommodate variation in the gears. <IMAGE></p> |
