HIGH LINE-OF-ACTION RATIO LOW CHUCK SEAT RECLINER

摘要: A releasably lockable automotive seat back hinge linkage device includes a hingedly interconnected support arm and cushion side plate, which are arranged to be relatively rotatably positionable in an at least one mutually locked position, about first common pivot. pivotable locking pawl is rotate relative the plate second pivot therewith. The surface adapted pivotally engage complimentary engaging portion of arm, forced transferring relation along line action. cam included selectively rotatable third operable for follower lines action offset from another. rotationally bias into pivotal engagement with portion, operably secure position. Forces that transferred through respective ones combine vector sum rigidly take up first, degrees lost motion inter-engagement whereby associated as result mechanical clearances respect pivots, taken up, thereby reduce chuck whole.
