Abstract: A folding passenger seat assembly with integral child restraint for a motor vehicle includes a seat portion and a backrest portion hinged to the seat portion. A seat latch finger selectively locks the backrest portion in a vertical use position. A child seat is integrally recessed within the backrest portion and includes a hinged bottom cushion. The backrest portion and child seat are interlocked so that the bottom cushion of the child seat can only be deployed if the backrest portion is latched in its vertical use position. Conversely, the backrest portion cannot be folded down if the child seat is deployed. The child seat includes a throw bolt at its hinge point for constantly and unyieldingly locking the bottom cushion in its stowed condition until deliberately released therefrom. Such deliberate release is accomplished by a footrest actuator on the bottom cushion.

Abstract: A motor vehicle includes a folding passenger seat assembly having a seat portion and a backrest portion. The backrest portion has a left end and a right end both of which are hinged to the seat portion so that the backrest portion can be folded from a vertical use position to a horizontal non-use position. A child safety seat is secured to the backrest portion. The left hinged end of the backrest portion is provided with a manual latch for selectively locking the left end of the backrest portion in the vertical use position. The right end of the backrest cushion is provided with an inertial latch for automatically locking the right end of the backrest portion in its vertical use position only in response to sudden deceleration of the motor vehicle. Weight, component cost and labor are conserved by installing the manual latch on only the left end of the backrest portion to lock it in its vertical use position.
