Abstract
Variable clutching seat recliner apparatus includes a drum coupled to a seat back, a band wrapped about the drum inhibiting rotation thereof, a tightening mechanism coupled to opposed ends of the band such that a force applied to the seat back in either of two opposing directions produces a tension in the band adjacent either end and a corresponding loosening of the band adjacent the other end. The tightening mechanism includes a lever pivotable about a fixed pivot point to convert a portion of the tension to reduce the loosening, and a variable control mechanism positioned proximate the lever for limiting pivotal movement of the lever.
