Abstract: A pivot assembly for a structured vehicle seat assembly accommodates loads applied to the seatback through a safety belt restraint system carried by the seat assembly. The pivot assembly includes a connector member including an upper portion extending into a hollow channel defined by the seatback frame. The connector member is fixedly attached thereto. The pivot assembly further includes a housing attached to a lower seat structure for movement therewith between fore and aft positions. The connector member is pivotally mounted to the housing to thereby permit the seatback to rotate relative to the lower seat structure between a generally upright position and a reclined position. The pivot assembly further preferably includes a drive arrangement for rotating the connector member about a pivot axis. The pivot assembly functions to efficiently and effectively transfer loads from the seatback to the lower seat structure, and in turn, to the vehicle structure.
