Abstract: A motor vehicle seat system includes a row of front seats, a row of back seats separated from the row of front seats by a lateral isle, a longitudinal aisle through the front row, and a middle seat in the back row having a full-row position behind the lateral aisle and a half-row position overlapping the front row and the lateral aisle. In its full-row position, the middle seat cooperates with the back row seats for bench-type seating. In its half-row position, the middle seat provides a rigid platform for a child seat closer to occupants of the front row seats. The middle seat includes a removable lower frame, a seat cushion frame, a seat back frame pivotally connected to the seat cushion frame, and a mechanical linkage supporting the seat cushion frame on the lower frame for translation between an extended position corresponding to the half-row position of the middle seat and a retracted position corresponding to the full-row position of the middle seat.

Abstract: A foldable motor vehicle seat including a horizontal seat cushion and a vertical seat back joined at a horizontal hinge for pivotal movement of the seat cushion from a horizontal position to a vertical position folded against the seat back. The seat back is connected to a side wall of a body of the motor vehicle for pivotal movement about a vertical axis between a seating position in a plane perpendicular to a longitudinal centerline of the motor vehicle and a cargo position in a plane parallel to the longitudinal centerline. With the seat cushion folded vertically against the seat back and the seat back in its cargo position, the floor of the motor vehicle under the seat is exposed for cargo. With the seat cushion horizontal and the seat back in its seating position, a passenger may sit on the foldable seat.

Abstract: A tumble forward seat for a van or the like includes a device to automatically unlatch the seat adjuster, return the seat from any forwardly adjusted position to its rearwardmost position, and relatch the seat adjuster, during the forward rotation. A specially designed cam and lift lever push the pivoting release handle of the seat adjuster up and open and hold it open while a wedging surface and pusher block react against one another to shift the seat cushion frame back. The lift lever resets itself as the seat is rotated back. The cam, lift lever, and wedging surface are coordinated to one another so as to always provide the correct degree of opening and shifting motion, regardless of initial seat adjusted position.
