1. A disc recliner for a vehicle seat, said disc recliner comprising: a fixed plate including a plurality of outer teeth; a movable plate including a plurality of inner teeth meshingly engageable with said plurality of outer teeth on said fixed plate to allow rolling movement of said movable plate relative to said fixed plate; a pair of wedges rotatably mounted between said fixed and movable plates, wherein said pair of wedges define an eccentric and rotation of said pair of wedges causes said rolling movement of said movable plate relative to said fixed plate; a lock anchor disposed between said pair of wedges for rotation therewith; a lock plate coupled to said lock anchor and movable between a locked position engaged with said fixed plate to block movement of said lock anchor thereby preventing rotation of said pair of wedges and an unlocked position disengaged with said fixed plate to allow movement of said lock anchor thereby permitting rotation of said pair of wedges; a lock spring operatively coupled between said lock plate and said lock anchor for biasing said lock plate to said locked position; and a cam for rotatably driving said pair of wedges and actuating said lock plate between said locked and unlocked positions, wherein rotation of said cam actuates said lock plate from said locked position to said unlocked position and rotates said pair of wedges thereby causing said rolling movement of said movable plate relative to said fixed plate.
