摘要

A seatback recliner mechanism incorporated into a vehicle, the seat including a seat bottom and a pivotally engaged seatback. The recliner mechanism includes a pair of lower supports forming a part of the seat bottom and secured to at least one of first and second sides of the seat bottom. A first gear is fixed between the lower support and at a generally upper end and a pair of upper supports are pivotally secured to the lower supports and include a second rotatable gear meshingly engaged with the first gear. The seatback includes an upper arm pivotally secured to the upper support in coaxial fashion relative to a third rotatable gear meshingly engaged with the second gear. A first lever is operative to pivot the upper support relative the lower support over a specified range of forward incline and rearward recline. A second lever is operative to pivot the upper arm, relative to the upper support, to a substantially forward and horizontal position. A third lever unseats and rotates an intermediate plate, disposed between the upper and lower support plates and operatively engaged to the upper support plates in the released position, to a predetermined and forwardly inclined position.
