Abstract
A seat interlock system for use with a vehicular seat having a fold-down seatback equipped with a deployable integral child seat. An interlock mechanism is interdisposed between a seatback latching mechanism and a child seat latching mechanism. When the seatback is in its normal upright and latched condition, the interlock mechanism permits the child seat to be deployed. If the seatback is not latched, a movable member of the interlock mechanism prevents deployment of the child seat. Upon deployment of the integral child seat, the movable member interacts with the seatback latching mechanism in such a way as to prevent the seatback from being unlatched, thereby preventing folding of the seatback. The seat interlock system also includes an inertia responsive latching mechanism for preventing deployment of the integral child seat when the seatback is subject to a deceleration force exceeding a predetermined threshold value.
