Abstract
A vehicle seat includes a seat base and a seat back rotationally connected at a pivot. The seat base is rotatable about the pivot between a plurality of rotational positions relative to the seat base. A recliner disk is positioned at the pivot. The recliner disk includes a guide plate coupled to the seat base and a tooth plate coupled to the seat back. A plurality of bearings is positioned between the guide and tooth plates. The plurality of bearings and the guide and tooth plates are free of an internal braking mechanism. The engagement of the guide and tooth plates with the bearings provide for substantially free rotational movement between the plurality of rotational positions. The bearings also fix the relative axial position of the guide plate relative to the tooth plate.
