  • Patent number: 7429082
    Abstract: A vehicle seat with a headrest for a vehicle is formed from an impact cushion and installed upon a seat back. The headrest is pivoted around a stationary pivotal axle aligned transversely to a longitudinal axis of the vehicle and can be swung from an unused position against the force of a spring into a used position. In the used position, the headrest is held stationary by a toggle linkage, which, within its self-limiting swing zone, acts as a pivoting element between the impact cushion and the pivotal axle.

  • Publication number: 20070267099
    Abstract: The device includes a protective mechanism for preventing introduction of a gasoline-type nozzle into an inlet passageway of a fuel tank of a Diesel motor vehicle, the inlet passageway defining a central axis, the protective mechanism comprising two arms mounted at least partially within the inlet passageway, the arms being pivotable around a pivot axis substantially parallel to the central axis. A connector is mounted at least partially within the inlet passageway, the connector being movable in a plane transverse to the central axis, movement of the connector outwardly from an idle position relative to the central axis causing the arms to pivot from an idle position toward a free-flow position. The connector is configured so that insertion of a gasoline-type nozzle into the inlet passageway will not move the arms to the free-flow position, whereas insertion of a Diesel-type nozzle into the inlet passageway will move the arms to the free-flow position.

  • Patent number: 7204279
    Abstract: A vehicle tank includes an intake tube, on the end of which is placed a filling-fixture containing an automatic tank closure. The filling-fixture is made of one piece with the intake tube. The automatic tank closure is integrated in an insert. The filling-fixture forms a recess on its upper end into which the insert can be placed. A fissure joint is sealed with the aid of a sealing element between the filling-fixture and the insert and the securement of the insert in its recess is assured by a retaining flange. The flange is circumferentially connected in a radially outlying area with the filling-fixture and the flange extends so far radially inward that it covers the fissure joint and an inward extending area of the upper side of the insert.

  • Patent number: 7147018
    Abstract: The invention concerns a filling fitting for a fuel tank of a motor vehicle having an automatic tank closure. The filling fitting includes a carrier with an inlet opening and a closure cover, which closes the inlet opening with a sealing element. An upper side of the closure cover has a closure component, which, in a closed position of the closure cover, penetrates the inlet opening. Above the carrier is a circumferential section placed directly or indirectly on a supporting closure ring. The section extends inward to coact with closure elements on the closure component in the manner of a screw drive. To prevent permeation, in a force transmission path between the sealing element of the closure cover and the carrier, at least one axial, effective spring element is inserted.

  • Patent number: 6874529
    Abstract: The invention concerns a level limit valve for the fuel tank of a vehicle. Such valves serve the purpose, that upon the filling of the fuel tank, the filled quantity of the fuel is limited. The proposed level limit valve possesses a valve body 1 which can be positioned within the fuel tank at the end of a filling pipe. The valve body is equipped with an intake port 22 which is connectable with the said filling pipe and an outlet port 21 emptying into the interior of the fuel tank. Further, in the valve body 1 is found a flap 4, which is pivotally movable between a position tightly sealing the outlet port 21 and a position wherein this is opened. The float 3 is movably connected to said flap 4 by means of a lever rod 5. The lever rod 5 penetrates the outlet port 21 at least in the opened position of the flap 4 and is connected by means of linkage with that outer side 28 of the flap 4 which is proximal to the outlet port 21.
