  • Device for fixing a child seat to the seat of a motor vehicle
    Patent number: 6196628
    Abstract: The fastening device consists of at least one retaining element 13 attached to the seat of the vehicle, this element holding a fastening element 14, which can be moved between a service position and an out-of-service position (parking position). So that the fastening element 14 can be moved easily into the service position and then again into the parking position without the need for any force-transferring element installed at a remote location, the fastening element 14 is connected to the retaining element 13 by means of a latching mechanism 17, which makes it possible for the fastening element 14 to be lowered into a parking position and returned to a service position.
