  • the invention relates to a tailgate assembly for a passenger car specified in the preamble of claim 1. Art.
  • tailgate assemblies Due to the increased desire in recent years for variable passenger cars, a considerable demand for tailgate assemblies has arisen, with which in particular motor vehicles with steeply sloping rear end such as combination cars, off-road vehicles or SUVs are provided to enable, for example, an uncomplicated loading of the cargo space.
  • the tailgate assembly in two parts with an upper tailgate part and a lower tailgate part.
  • the upper tailgate portion is usually to move to an associated bearing axis between a closed position and an open position, in which this comes to rest in a vicinity of a rear upper end of the roof.
  • the lower tailgate portion is nowadays usually displaced about a bearing axis between a closed position and an open position, which at the rear end of a loading floor or a loading edge runs. If the lower tailgate part is thereby transferred to the open position, this extends approximately in extension of the loading floor.
  • Object of the present invention is to provide a tailgate assembly of the type mentioned, by means of which a particularly comfortable and space-saving access to the cargo space of the passenger car is possible.
  • Tailgate assembly solved with the features of claim 1.
  • Advantageous embodiments with expedient and non-trivial developments of the inventions are specified in the dependent claims.

  • the lower tailgate part is provided according to the invention in contrast to the prior art, to shift in such an open position that it comes to rest below the upper tailgate part and also in the vicinity of the rear upper end of the roof.
  • both tailgate parts are located in the upper region of the opening of the passenger car which can be closed by the tailgate arrangement, this opening is thus accessible particularly comfortably.
  • the hitherto in the Open position in the lower region of the opening remaining tailgate part can now also be pivoted into an upper region of the opening or in the vicinity of the rear upper end of the roof, so that a person loading the inner load compartment up to the bumper or the opening of the Passenger car can approach.
  • the tailgate arrangement according to the invention makes it possible in a simple manner to release the at least approximately entire opening, which can be closed by the tailgate arrangement, for a laden person.
  • the two tailgate parts can be easily displaced in such a height in its open position that large people can move accordingly below the two open tailgate parts.
  • Another advantage is that a good rain protection is maintained by the two tailgate parts in their open position, so that, for example, no moisture gets into the interior of the passenger car.
  • the two tailgate parts are arranged in their respective open position substantially parallel to each other. It should be noted that the two tailgate parts have a certain curvature or crowning, but the two parts are stacked so that an extremely space-saving arrangement of the two located in their open position tailgate parts results.
  • the lower tailgate part is mounted on the side of the vehicle by a respective lateral four-bar linkage.
  • the lower tailgate part can be made correspondingly large or solid, since such four-bar linkages can be designed to hold considerable weights.

  • a positive clutch and / or automatic provided by means of which when closing the upper tailgate part automatically close the lower tailgate part. This results in the same advantage when closing the two tailgate parts.
  • a weather protection is provided, which remains stationary on the side of the vehicle. This results in particular the advantage that when the tailgate parts open a secure protection is created, for example, prevents raining into the interior of the motor vehicle.
  • the two tailgate parts are to be displaced in a particularly automatic sequence between the respective closed position and the respective open position.
  • the automatic ensures reliable, that there is no collision between the two tailgate parts the respective shift from the closed position to the open position - and can come back.
  • a further advantageous embodiment provides that the two tailgate parts are to be displaced in an at least approximately synchronous, in particular automatic sequence of movements between the closed position and the open position.
  • Opening movement of the two tailgate parts can thus be achieved particularly fast closing or opening of the tailgate assembly.
  • the two tailgate parts are to be displaced independently of one another between the closed position and the open position, then it is possible in particular for the upper tailgate part to be opened, during which the lower tailgate part remains in its closed position.
  • the upper tailgate part is opened, for example, when the load compartment is to be filled only with small loads.
  • 1 is a slightly perspective side view of a passenger car with steeply sloping tail or steeply sloping tailgate assembly, which comprises an upper, substantially clad by a disc flap part and a lower, substantially clad by a participatbeplankung tailgate part, wherein the two tailgate parts or the tailgate assembly shown in its entirety in its closed position;
