Abstract
A seat recliner assembly established at a hinge location between a seat bottom and a pivotally associated seat back including a base plate and an inwardly teethed and package supporting sector secured to the seat back and seat bottom, respectively and sandwiched together in selectively rotatable fashion relative to define a component receiving space therebetween. A shaft projects through an aperture of a rotatably slaved cam situated within the space. A pair of locking pawls with exteriorly toothed surfaces are displaceable to engage with inwardly teethed locations of the package supporting sector. A pair of anti-chuck pawls are selectively engagable both by the cam and with the locking pawls. The cam is biased in a first rotational locking condition to influence the anti-chuck pawls outwardly against the locking pawls. The cam is rotated in an opposite and counter-biasing direction, thereby directly contacting the locking pawls and pivoting the same such that their exteriorly toothed surfaces are inwardly disengaged from the teethed sector, permitting rotational between the base plate and package sector.
