Abstract
A seat recliner is provided comprising a seat back support mounted at a pivot pin to a base frame. A sector gear is affixed to the seat back support and includes an opening through which the pivot pin passes. A first gear set is mounted on a pin in the base frame and includes a first gear meshed with the sector gear and a second gear. A second gear set is also mounted on a pin in the base frame and includes a first gear meshed with the second gear of the first gear set and a second gear. A clutch spool is mounted on a pin in the base frame and includes a gear meshed with the second gear of the second gear set. A coil spring surrounds the clutch spool. When the spring is tensioned, the clutch spool is prevented from rotating and the seat back is held from rotational movement about the pivot pin. A clutch release plate contacts the spring coil in a manner such that a selected movement of the release plate decreases the coil spring tension on the clutch spool. This permits rotation of the clutch spool and subsequent rotational movement of the seat back support.
