A vehicle seat assembly is disclosed containing an integrated child seat having a child seat cushion and headrest stored within the seat back of the seat assembly. The child seat is deployed by raising the child seat headrest from an upper portion of the seat back and rotating the child seat cushion from the seat back forward to a generally horizontal use position overlying the adult seat cushion. The seat assembly of the present invention includes a floating pivot axis for the child seat cushion to enable the seat cushion attaching hardware to be placed rearward from the face of the seat back to improve adult seating comfort. The buckle for the child seat restraint system is pivotally mounted directly to the child seat cushion enabling a user to easily insert a latch plate of the restraint system into the buckle with one hand freeing the other hand for restraining the child. The child seat further includes a protective flap extending forward from the child seat cushion to protect the upholstery of the adult seat cushion from wear and dirt from the shoes of a child seat occupant.
