Seat recliner with single-position-memory dump mechanism

摘要

A seat-back motion controller is used in a foldable vehicle seat to control motion of a seat back relative to a seat base. The motion controller includes a seat recliner configured to be locked to retain the seat back in a selected reclined position and unlocked to free the seat back to be pivoted forwardly to assume a forward-leaning seat-back dumping position to facilitate passenger access to a back seat area in a vehicle.
