A vehicular seating system includes a seat cushion pivotably attached to a support structure, with the said seat cushion having a stowed position and a deployed position. A base latch selectively secures the seat cushion in its deployed position. A seatback is hinged to the seat cushion, with the seatback having a folded position and an unfolded position. A base latch interlock is configured to permit the base latch to release only when the seatback is in its stowed, folded position.
