  • Patent number: 5647634
    Abstract: The present invention is directed to a "fold-out" or integral child seat having a mechanism interconnecting a seatback member, a headrest member and a seat member for causing coordinated movement therebetween. When it is desired to deploy the integral child seat, the seatback member is moved to a tilted position and the headrest member is elevated while the seat member is moved to a lowered position for establishing an upright sitting position. Additionally, the integral child seat may be deployed to a reclined position wherein the seatback member is automatically moved to a second tilted position and the headrest member is moved to a second elevated position in coordination with the movement of the seat member to a second lowered position. As a result, movement of the integral child seat between its stowed and first and second deployed positions can be accomplished with relative ease and convenience to the person attempting such movement.

  • Patent number: 5603550
    Abstract: A seat interlock system for use with a vehicular seat having a fold-down seatback equipped with a deployable integral child seat. An interlock mechanism is interdisposed between a seatback latching mechanism and a child seat latching mechanism. When the seatback is in its normal upright and latched condition, the interlock mechanism permits the child seat to be deployed. If the seatback is not latched, a movable member of the interlock mechanism prevents deployment of the child seat. Upon deployment of the integral child seat, the movable member interacts with the seatback latching mechanism in such a way as to prevent the seatback from being unlatched, thereby preventing folding of the seatback. The seat interlock system also includes an inertia responsive latching mechanism for preventing deployment of the integral child seat when the seatback is subject to a deceleration force exceeding a predetermined threshold value.

  • Patent number: 5597206
    Abstract: A manually-adjustable seat assembly for use in motor vehicles is disclosed as having a manual seat adjuster equipped with a seat latch mechanism and an easy entry latch release mechanism. The seat latch mechanism can be manually shifted from a latched mode into an unlatched mode via actuation of a release handle to permit selective adjustment of the fore/aft position of the seat assembly. The east entry latch mechanism is operably connected to the seat latch mechanism and is normally maintained in a non-actuated mode. Pivotal movement of the seatback to a forwardly dumped position causes the easy entry latch release mechanism to be shifted into an actuated mode for causing the seat latch mechanism to be automatically shifted into its unlatched mode. Upon return of the seatback from its formally dumped position, the east entry latch release mechanism is maintained in this non-actuated mode until the seat assembly is slid rearwardly to a predetermined memory position.
