Definitions

  • the invention relates to a passenger car in which the front or, in particular, tailgate is hinged with its flap edge adjacent to the adjacent window of the motor vehicle on a pivot bearing plate of a hinge and is pivotable.
  • the invention is intended in particular for motor vehicles in which the flap edge adjacent to the inclined window lies above the lower fold area of the window when the flap is closed. However, it can also be used if there is no such covering of the lower edge of the window by the flap. In addition, although the invention can also be applied to bonnets, it is preferably applied to bonnets.
  • arch hinges can be provided from an approximately U-shaped bracket, at the rear end of which the flap is fixed with its front edge and the front end of which is articulated below the rear window on a swivel bearing plate fixed to the vehicle.
  • the length of the bracket must be greater the further the front edge of the flap protrudes beyond the fastening point of the flap on the bracket and therefore the flap has to be raised when swiveling open in order to avoid a collision with the rear window.
  • the bracket must be relatively long. This will fix the stability of the tailgate is reduced and the space required for the bracket in the trunk of the motor vehicle is increased when the hatch is closed.
  • the accessibility of the area of the lower window rebate can be impaired both when the flap is closed and when it is open. In this case, the flap must be removed again after it has been preassembled and adjusted to the shell or to replace the rear window so that the rear window can be installed.
  • the object is achieved to create a passenger car of the type mentioned, in which there is no risk of collision for the window pane when the flap is open, even when the flap edge is pulled far toward the adjacent window of the motor vehicle, nor is the assembly of the Window pane is hindered by the mounted flap.
  • the pivot bearing plate is displaceable in a guide rail in the vehicle longitudinal direction, that between the flap edge articulated on the pivot bearing plate and the guide rail, a gear engaging on the pivot bearing plate is switched on, of which the pivot bearing plate is pivoted by a predetermined amount Flap in the direction facing away from the window, and when the flap is swiveled in the direction facing the window, it is inevitable that the gear can be uncoupled when the flap is open in such a way that the pivot bearing plate can be moved by an additional amount in the direction facing away from the window and the flap can be swung out.
  • the flap edge adjacent to the window is simultaneously displaced away from the flap when the flap is swung open, so that even with a small size of the hinge parts, even when the flap edge is advanced far to the window, a flap collision occurs can be prevented with the window pane when the flap is swung open.
  • the flap edge of the flap is inevitably moved back to the starting position, so that the flap gap that has been set is restored exactly.
  • the gear which controls the inevitable displacement movement of the flap during normal operation can be uncoupled if necessary and the flap can thereby be displaced and pivoted away from the window by an additional amount, the flap whose flap edge in the normal closed position is relatively wide is pulled towards the window, assembly of the window pane is not hindered by the flap.
  • the flap can be placed in the pivoted-down position on the frame part of the opening which can be blocked off by the flap and which is turned away from the window, without its swivel fastening on the swivel bearing plate being released.
  • the flap is swung open again and the transmission is engaged again, after which the flap is swiveled down again and inevitably returns to its normal closed position.
  • a special coupling or locking element can be provided for engaging and disengaging the transmission, which can preferably be operated without tools in a predetermined pivoting-open position of the flap. It is also possible to ensure through the design of the transmission that when the flap is fully opened, the transmission members to be decoupled e.g. disengage by slightly manually moving the swivel bearing plate in the direction facing away from the window. It can be advantageous here to ensure, by means of an elastic stop, a ball catch or the like, that the flap can only be swung open into this completely swung open position, in which the gear members can be moved apart, after overcoming a small resistance. This prevents unintentional decoupling of the transmission during normal operation of the flap.
  • the transmission is preferably designed as a rack and pinion drive.
  • a gearbox can be accommodated in a compact, small size underneath the side edges of the flap outside the usable space covered by the flap in the water drainage channel which is present anyway.
  • a tailgate compared to the conventional arch hinges that plunge into the usable space when the flap is closed, not only is better utilization of the usable space achieved and the risk of damage to objects avoided, which get into the freedom of movement of the arch hinges. Rather, such a design of the gearbox and its placement outside the usable space can prevent other installations from being impaired by the presence of the hinge.
  • the outer position of the hinge can prevent any obstruction when installing the tank if the tank is to be installed in the safety zone of the usable space above the rear axle, but the flap is already installed.
  • the tank filler tube no longer needs to be directed around the hinge, as is usually required when arched hinges are present, or, for example, the outlet cross-sections of air ducts are not hindered by the presence of the pivot bearing plate of the hinge.
  • the gear has a gear segment rotatable with the flap about its pivot axis, a lower rack formed on the guide rail and a between this and arranged on the gear segment, engaging with the gear segment and mounted on the pivot bearing plate, which engages in the inevitable displacement of the pivot bearing plate in the lower rack and can be uncoupled from the latter when the flap is pivoted open.
  • the pinion when the flap is swung open, the pinion is rotated by the gear segment, so that it rolls on the rack and is displaced accordingly by its mounting on the pivot bearing plate.
  • the toothed rack can end at a point at which the pinion may move away from it after overcoming elastic resistance runs and is uncoupled from the rack. Then the pivot bearing plate is no longer supported on the rack and can be shifted by the desired additional dimension, the pinion freewheeling. As a result, the flap can be pivoted away.
  • a second, upper toothed rack is preferably formed on the guide rail, which is offset relative to the lower toothed rack in the direction facing away from the window and which engages with the pinion for moving the swivel bearing plate by the additional dimension from above.
  • the aerodynamic shape optimization of a passenger car can result in accordance with FIG. 1 that the tailgate 1 overlaps the lower frame part of the window 2 with its flap edge 3 adjacent to it because of the flat inclined installation position of the tailgate 2.
  • the flap 1 is articulated on the motor vehicle via fastening arms 11 which are drawn far around the rear window 2, so that its pivot axis 9 lies below the window.
  • the pivot axis 9 is simultaneously shifted backward by a predetermined amount a, as shown in FIG. 2, so that the front flap edge 3 of the swung-open flap 1 does not abut the pane of the window 2 and therefore neither the pane nor the flap edge 3 is damaged can be.
  • the flap 1 is installed in front of the window 2 window. Because of the overlap d of the lower window frame part through the front flap edge 3, however, the pane of the window 2 cannot be installed either with the flap 1 closed according to FIG. 1 or with the flap 1 open according to FIG. 2. Nevertheless, in the motor vehicle shown, the window 2 is installed without removing the flap 1 for the window assembly and reinstalling it after the window Assembly possible because the flap 1 according to FIG. 3, if necessary, can be moved back and swung out from the swung-open position by an additional dimension b.
  • the front edge of the front flap edge 3 is offset to the rear by a sufficiently large distance c from the lower frame part of the window, as a result of which the pane 2 can be installed without any risk of damage to itself or the flap edge 3. Accordingly, the pane of the window 2 can be replaced by a new pane without having to remove the flap 1.
  • FIG. 4 shows an embodiment of a flap hinge with which the displacement options for the flap 1 described with reference to FIGS. 1 to 3 are realized.
  • the pivot bearing plate 4 on which the flap 1 is pivotably pivoted about the pivot axis 9, is guided in a guide rail 5 so as to be displaceable in the longitudinal direction of the motor vehicle.
  • the pivot bearing plate 4 which is designed as an angle plate, engages in an angular guide gap 2 of the guide rail.
  • a vertically standing, downwardly projecting gear segment 6 is formed such that the center of its tooth circle lies in the pivot axis 9 of the flap 1.
  • the gear segment 6 engages from above in a pinion 7, which is rotatably mounted in the pivot bearing plate 4 below the pivot axis 9 and offset against it to the rear.
  • the pinion 7 also engages in a lower rack 8 which is formed on the guide rail 5.
  • an upper rack 10 is formed on the guide rail 5, which is arranged offset to the rear relative to the lower rack 8.
  • FIGS. 9 and 10 corresponds to that of FIGS. 5 to 8 with the exception that the rear upper rack 10 is missing. Therefore, if the pinion 7 in the position according to FIG. 9 has run off the lower rack 8, the fastening arm 13 of the flap can be pivoted with the latter, the pinion 7 running freely, and in doing so, until it starts up against the rear stop 15 of the guide rail be pulled at the rear, whereby the flap is displaced by the additional dimension b.
  • the position of the hinge parts in this position of the pivoted and pulled back position is shown in Fig. 10.
  • the guide rail 5 is fixed outside the access opening of the usable space on the bottom of the lateral water drainage channel 14.
  • the gear segment 6 and the racks 8 and 10 are laterally offset from one another, so that the height of the pivot axis 9 above the lower rack 8 is smaller than the radius of the toothed circle of the gear segment 6 can be without this colliding with the lower rack 8.
  • the gear segment 6 and the swivel plate 4 are arranged perpendicular to the longitudinal direction of the vehicle at such a distance that the lower rack 8 and the upper rack 10 can protrude between the gear segment 6 and the swivel bearing plate 4.
