1. A recliner assembly for a vehicular seat of the type including a backrest hingedly connected to a seat cushion and capable of being rotated, said assembly comprising:
a toothed rotary recliner mechanism configured to establish incremental reclining adjustments about a generally horizontal axis to permit relative pivotal movement between a backrest and a seat cushion, said rotary recliner mechanism including opposing inner and outer gears supported relative to one another for rotation about said axis, said outer gear including internal teeth arranged circumferentially about said first axis and facing said axis, and said inner gear including at least one tooth engaging member facing away from said first axis and selectively moveable into and out of engagement with said internal teeth so as to arrest relative rotation between said inner and outer gears when engaged with said internal teeth; a base plate configured for fixed connection to the seat cushion and a top plate configured for fixed connection to the backrest, said base plate being fixedly joined to one of said inner and outer gears, and said top plate being fixedly joined to the other of said inner and outer gears of said recliner mechanism for relative arcuate displacement about said first axis; a retainer configured for fixed connection to said outer gear; and wherein said retainer plate is configured to retain said inner gear laterally with respect to said outer gear, wherein the retainer has an outer flange including at least one detent extending toward said base plate and wherein said base plate includes maximum travel stops for interaction with said detent on the retainer, and in operation, in the event that the rotation of said base plate to backrest of the seat exceeds a predetermined limit, said detent bottoms-out on said maximum travel stops to aid with stopping the rotation. |
