<p>A disc recliner for a seat assembly includes a gear plate disposed between fixed and movable plates. The gear and fixed plates are operatively coupled by a pawl that is selectively engaged with the fixed plate. An eccentric element is coupled between bearing surfaces on the gear and movable plates causing a plurality of inwardly-facing teeth on the movable plate to meshingly engage with a plurality of outwardly-facing teeth on the gear plate at an engagement point. When the pawl is disengaged from the fixed plate, the gear and movable plates rotate together relative to the fixed plate to freely pivot a seat back to a folded position. When the pawl is engaged with the fixed plate, rotation of the eccentric element shifts the engagement point and causes wobbling rotational movement of the movable plate relative to the gear plate to pivot the seat back between reclined seating positions.</p> |
