Abstract: A child restraint system which is an integral part of and folded into a land vehicle or aircraft adult seat is described. The integral child restraint system may be unfolded from the front portion of the back of an adult seat to form a comfortable child safety seat. A padded restraint bar also unfolds simultaneously with unfolding of the integral child safety seat to further restrain the child in the event of a crash. Also included is a belt restraint system, very similar to an approved portable child seat, attached to the child's safety seat frame. When the integral folding child safety seat is folded into its stored position, a normal padded passenger seat back is formed which is comfortable to an adult passenger sitting in the seat. A detachable tray fitted on the padded restraint bar is also included.
