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 which meshes with a gear. A locking pawl is movable between a position of engagement with the gear to fix the seat back angle to a disengaged position, permitting the seat back angle to be adjusted. Further, a restraint pawl is provided which acts upon the curved toothed rack in the event that the locking pawl or recliner gear fails, thereby providing a redundant means for fixing the relative angular position between the upper and lower recliner structures.
