Vehicle seat assembly with integrated child seat

A vehicle seat assembly is disclosed which includes an integral child seat that can be deployed for use in seating a child or maintained in a stowed position enabling the seat to be occupied by an adult. The seat assembly includes a pair of panels movably mounted to the seat back. When the side panels are moved outwardly, they extend forwardly from the seat back forming side bolsters for the child seat. Troughs are revealed adjacent to the side bolsters which contain the shoulder belts of the child restraint system. The child seat back cushion is disposed between the two troughs and is comprised of the same seat back surface as used by an adult when seated in the seat assembly. As a result of using the same seat back surface for both the child seat and an adult, the seating comfort of the adult seat back is maintained at the same level as with a conventional seat assembly not having an integral child seat.
