Abstract
A gear operated seat recliner mechanism is described which is particularly useful in connection with motor vehicle occupant seats. The recliner permits the angle between the seat back and seat bottom to be varied as desired by the seat occupant. In accordance with this invention, the upper recliner structure pivots about the lower recliner structure and a quadrant component, which pivots with the upper recliner structure, includes a curved toothed rack. The rack meshes with a gear mounted to the lower recliner structure. A pawl is adjustable between an engaged position which fixes the seat back angle to a disengaged position permitting the seat back angle to be changed relative to the seat bottom. This design improves over prior art designs in that it employs fewer parts, is less costly to produce, and further, permits very fine adjustments in the seat back angle.
