DETAILED DESCRIPTION

[0045] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0046] FIG. 1 shows in a detail and in perspective view with a view of an inner side facing the vehicle interior, a vehicle door of a motor vehicle. A door shell construction T of the vehicle door in this case is formed by a first shell component in the form of a door inner skin 1 and a second shell component in the form of a frame reinforcement 3. The door shell construction T defines in this case, on the one hand, a window opening O which in the intended assembled state of the vehicle door may be closed by an adjustable window pane. On the other hand, the door shell construction defines fastening points for a module component in the form of a door module 2 to be arranged in the vehicle door. This door module 2 closes a cavity provided in the vehicle door and is provided for carrying different functional components of the vehicle door, such as for example a loudspeaker, as well as functional components of a window lifter provided for adjusting the window pane.

[0047] The door module 2 defines, on the one hand, a support surface 20 to which the different functional components may be fastened. This support surface 20 is substantially formed by an organic sheet. Different reinforcing and interface structures 21 as well as a module edge 22 are injection-molded onto this support surface 20 from a plastics material, for example a fiber-reinforced polypropylene. Potential reinforcing structures are formed here, for example, by reinforcing ribs. The interface structures define, for example, fastening points for the fastening of the door module 2 to the door shell construction T as well as for attaching functional components to the door module 2, such as for example an interface for connecting a drive motor of the window lifter or an interface for the attachment of a loudspeaker. The module edge of the door module 2 circulating over the periphery is also configured by the injection-molded plastics material, as well as a flange section 23 extending in a strip-like manner on an upper edge of the door module 2.

[0048] The flange section 23 serves primarily for forming a sill flange F on the sill of the window opening O. A channel seal 5, not shown in FIG. 1, may be secured to this sill flange F in order, such as, to protect the interior of the vehicle against the penetration of moisture via the window opening O.

[0049] (0049) In this case, the flange section 23 on the module side forms only one part of the sill flange F. A further part of the sill flange F is defined by the door shell construction T. In this case, a flange section 33 of the frame reinforcement 3 extends along a longitudinal extension direction L between two longitudinal sides of the window opening O over the entire width of the window opening O and thus in the intended assembled state of the vehicle door opposite the flange section 23 of the door module 2. In each case, an edge-side flange section 10A or 10B of the door inner skin 1 is provided on the longitudinal side ends of the window opening O, said flange section also forming a part of the sill flange F.

[0050] An edge-side flange section 10A or 10B of the door inner skin 1 is shaped on a frame section 1A or 1B of the door inner skin 1 which, in the intended mounted state of the vehicle door on a vehicle, is arranged in the region of an A-pillar (frame section 1A) or a B-pillar (frame section 1B) of the vehicle (when the vehicle door is closed). The respective frame section 1A, 1B of the door inner skin 1 also defines in this case in the variant shown a part of the frame of the window opening running above the window sill.

[0051] The edge-side flange sections 10A and 10B of the door inner skin 1 protruding in each case in the direction of the opposing frame section 1B or 1A serve, for example, for fixing the door module 2 directly to the door inner skin 1. As is visible, for example, using the enlarged view of the FIGS. 2A and 2B, the sill flange F on a frame section 1A or a frame section 1B of the door inner skin 1 is constructed in three layers by three flange sections bearing against one another. In this case, both a flange section 10A/10B of the door inner skin 1 and a flange section 33 of the frame reinforcement 3 and the flange section 23 of the door module 2 bear against one another. An edge-side flange section 10A or 10B in this case is received in a sandwich-like manner between the module-side flange section 23 and the flange section 33 of the frame reinforcement 3. In the (central) region of the sill flange (F) between the frame sections 1A and 1B accordingly only the module-side flange section 23 and the flange section 33 of the frame reinforcement 3 oppose one another in order to form the sill flange F.

[0052] In order to ensure in this case a wall thickness d of the sill flange F which is uniform along the width of the sill flange F and thus a width of the window opening O, as well as to ensure a sufficient stiffness of the sill flange F, in the present case the module-side flange section 23 of the module assembly shown is configured with a plurality of contact regions 231, 232, 233 and 234 protruding in the direction of the opposing flange section 33 of the frame reinforcement 3. Each contact region in this case is formed by a bead 231, 232, 233 or 234 configured on the flange section 23 of the door module 2 running in a strip-like manner. The flange section 33 of the frame reinforcement 3 and the flange section 23 of the door module 2 thus only bear locally against one another over a large part of the width of the sill flange F.

[0053] On the beads 231 to 234 of the flange section 23 in this case a surface contact 41 is created between the frame reinforcement 3 of the door shell construction T and the flange section 23 of the door module 2. In the sill regions of the sill flange F located therebetween a gap 40 is located between the flange section 33 of the frame reinforcement 3 and the flange section 23 of the door module 2 and in each case in a sill region between a bead 231 or 234 and a longitudinal-side end region 23A or 23B of the module-side flange section 23, in which the module-side flange section 23 adjoining the respective frame section 1A or 1B bears against the associated edge-side flange section 10A or 10B of the door inner skin 1.

[0054] Via the beads 231 to 234 a gap 41 is bridged locally and at a plurality of points along the width of the sill flange F offset to one another, said gap resulting from the three-layered construction of the sill flange F on the (right-hand and left-hand) end regions of the window opening O. The resulting sill flange F consequently has a uniform wall thickness d over the entire width of the window opening O. By the merely locally provided beads 231 to 234 and a large-surfaced bearing, which is thus avoided, of the module-side flange section 23 on the flange section 33 of the frame reinforcement 3 of the door shell construction T over the entire width of the window opening O only a local metal-plastics pairing is provided between the metal door shell construction T and the flange section 23 of the door module 2 produced from a plastics material. Such a merely local bearing of the flange section 33 of the door shell construction T and the flange section 23 of the door module 2 takes into account the different tolerances and the variable warpage associated therewith of the different materials of the door shell construction T, on the one hand, and of the door module 2, on the other hand, which with a large-surfaced bearing against one another could potentially lead to problems when mounting the channel seal 5.

[0055] In principle, the beads 231 to 234 (and the alternatively designed protruding contact regions) may be spaced apart from one another and dimensioned such that an undulating contour of the flange section 23 of the door module 2 is present in longitudinal section. As an example, by varying the spacings and dimensions of the beads 231 to 234 of the flange section 23, the stiffness of the sill flange F which is formed thereby may be influenced in a targeted manner.

[0056] Optionally, in addition to the beads 231 to 234 additional partial sections may be configured with an undulating contour below the beads 231 to 234 on the flange section 23 of the door module 2. This undulating contour in this case may be designed in opposition of phase relative to an undulating contour defined by the beads 231 to 234 of the region of the flange section 23 located at the top.

[0057] In principle, instead of an individual bead or instead of a plurality of beads or all of the beads 231 to 234, at least one rib may also be provided, said rib ensuring a bearing of the flange sections 23 and 33 over the gap 40. Such a rib may, for example, be injection-molded on a module-side flange section 23. Alternatively or additionally, naturally the flange section 33 of the frame reinforcement 3 may also have one or more contact regions protruding in the direction of the flange section 23 of the door module 2. For example, protruding contact regions of the flange section 33 of the frame reinforcement 3 and of the flange section 23 of the door module 2 may alternate with one another along the width of the window opening O, respectively of the sill flange F.

[0058] The solution shown by way of example, in a channel seal 5 mounted according to FIGS. 3A to 3C on the door shell construction T and on the door module 2, ensures in a simple manner a permanently high sealing pressure onto the window pane to be provided on the window opening O, for example since the sill flange F in the case of a uniform wall thickness d has a sufficiently high stiffness. The different sections of the FIGS. 3A, 3B and 3C along the width of the sill flange F illustrate the uniform wall thickness d of the sill flange F in spite of the different number of flange sections 33, 10B, 23 and 33, 23 of the door shell construction T and of the door module 2 bearing against one another along the extension direction of the sill flange F between the two longitudinal-side edge sections 1A and 1B.

[0059] The channel seal 5 in this case has, in a manner known per se, an inner and outer seal 51 and 50 and is fixed via a plurality of fastening sections 500 to the window frame formed by the frame sections 1A and 1B of the door inner skin 1. In this case, the channel seal 5 is positioned via a positioning section 52 on the sill flange F such that the fastening flange F is encompassed by the positioning section 52 of the channel seal 5. The proposed construction of the sill flange F in this case ensures a simple mounting of the channel seal 5 and ensures a high connection strength between the channel seal 5 and the sill flange F.

[0060] As is visible with reference to FIG. 6, a combination of a door inner skin 1 and a frame reinforcement 3 forming the basis of the above-described variants, represents only one of a plurality of possible combinations for forming a door shell construction T. In a combination K2 of FIG. 6 based on the above-mentioned variants, the door inner skin 1 in the region of the sill of the window opening O only forms the edge-side flange sections 10A and 10B. A central region of the sill flange F between the two longitudinal sides of the window opening O is defined on the shell construction side by the elongated flange section 33 of the frame reinforcement 3 which, in the intended assembled state of the vehicle door, opposes the flange section 23 of the door module 2.

[0061] According to FIG. 6, however, for example a combination K1 of a door inner skin 1* and the frame reinforcement 3 is also conceivable in which the door inner skin 1* additionally forms a flange section 10* extending between the two longitudinal sides. This flange section 10* connects, therefore, the two frame sections 1A and 1B of the door inner skin 1 together. In a central sill region of the sill flange F, therefore, both the flange section 10* of the door inner skin 1* and the flange section 33 of the frame reinforcement 3 and also the flange section 23 of the door module 2 provided for forming the sill flange F are present in principle.

[0062] In a combination K3 of a door shell construction T, a door inner skin 1* is combined in turn with a continuous flange section 10* with a frame reinforcement 3* which in the sill region below the window opening O does not form a continuous flange section 33. In this variant the frame reinforcement 3* only forms two opposing and edge-side flange sections 33A and 33B extending toward one another. These flange sections 33A and 33B of the frame reinforcement 3*, comparable with the edge-side flange sections 10A and 10B of a door inner skin 1, thus serve for fixing the frame reinforcement 3* to the door inner skin 1* and for providing fastening points for the door module 2 on the longitudinal sides of the window opening O. A central sill region of the sill flange F in a vehicle door, which is produced from a door shell construction T with the door inner skin 1* and the frame reinforcement 3* and a door module 2, therefore, is consequently formed by the opposing flange sections 10* and 23 of the door inner skin 1* and of the door module 2.

[0063] Moreover, a door shell construction T may also be formed by a combination K4 according to FIG. 6. In this combination K4, the door inner skin 1 is combined with the edge-side flange sections 10A and 10B—and thus without a flange section 10* connecting both longitudinal sides—with a frame reinforcement 3* which also does not have a continuous flange section 33. In a vehicle door produced with such a door shell construction T, therefore, a central sill region of the sill flange F is exclusively formed by the flange section 23 of the door module 2. A stiffness of the flange section 23 on the door module side, which is sufficient therefor, may be achieved in this case by a corresponding ribbed section and/or beading of the flange section 23 and/or the use of a thick-walled organic sheet. Additionally, the flange section 23 may be configured with one or more rows of protruding contact regions, for example in the form of beads 231 to 234, as are used in the above-described FIGS. 1 to 3C or FIGS. 4A-4B and 5 described below. If the central sill region of the sill flange F is exclusively formed by the flange section 23 of the door module 2, the central sill region is designed entirely without a shell construction and thus without metal.

[0064] In a variant shown in FIGS. 4A and 4B, the door shell construction T is based on a combination K3 corresponding to FIG. 6, i.e. the combination of a door inner skin 1* with a flange section 10* with two edge-side flange sections 33A and 33B connecting the two frame parts 1A and 1B with a frame reinforcement 3*. Thus in the central sill region of the sill flange F, when the vehicle door is assembled as intended, the flange section 23 of the door module 2 and the flange section 10* of the door inner skin 1* assembled to the frame reinforcement 3*, oppose one another.

[0065] In this variant, the flange section 23 has a double-row undulating structure 230 with two partial sections provided one above the another, in which in each case protruding and non-protruding regions 231, 235, 232 or 232, 236, 233 which alternate with one another are provided along the longitudinal extension direction L. Between two beads 231 and 232 or 233 and 234 of such a partial section is located in each case an intermediate region 235 or 236 in which the flange section 23 does not protrude in the direction of the opposing flange section 10* of the door inner skin 1*. The two partial sections of the undulating structure 230 thus define in each case a row extending along the longitudinal extension direction L with protruding and non-protruding regions 231, 235 and 232 or 233, 236 and 234 alternating with one another. These regions 231, 235 and 232 or 233, 236 and 234 of a partial section define in each case an undulating contour in a longitudinal section.

[0066] The two rows are provided with their protruding and non-protruding regions 231, 235, 232 or 233, 236 and 234 running in opposition of phase on the flange section 23. Thus a bead 231 or 232 of an upper partial section, respectively a row of this upper partial section, in each case is located in the vicinity of a non-protruding intermediate region 236 of the lower partial section, respectively a lower row of this lower partial section. By the offset of the beads 231 to 234 arranged in opposition of phase relative to one another, in a side view of the mounted module assembly the beads 231 to 234 follow the path of an undulating line which extends along the longitudinal extension direction L. In side view both partial sections, therefore, define an undulating path for the individual contact regions of the flange section 23 protruding in the direction of the flange section 10* on the shell construction side, in the form of beads 231 to 234. At the same time, each partial section of the undulating structure 230 in longitudinal section defines an undulating contour.

[0067] By the corresponding offset of the beads 231, 232 and 233, 234 of the two partial sections, sealing lips of the channel seal 5 always bear locally against different types of region. Thus, for example, an upper sealing lip of the channel seal 5 bears against a bead 231 or 232 of the first upper partial section, whilst the other lower sealing lip of the channel seal 5 bears against a non-protruding intermediate region 236 of the second lower partial section. As a result, the penetration of moisture via the window sill is further impeded.

[0068] Deviating from the view of FIGS. 4A and 4B, in an alternative variant, two (for example in each case single-row) undulating structures on a door module side flange section 23, on the one hand, and a shell construction side flange section 10* or 3, on the other hand, may also be combined together. Relative to the window opening O, therefore, for example an upper (lower) row of alternately protruding and non-protruding contact regions may be configured on the flange section 23 of the door module 2, whilst a flange section 10* or 3 located therebelow (thereabove) of the shell construction T is provided with a row of alternately protruding and non-protruding regions—in the direction of the flange section 23 of the door module 2.

[0069] In the variant of FIG. 5 the module-side flange section 23 is also configured with an undulating structure 230. In this case, in contrast to the variant of FIGS. 4A and 4B, however, the undulating structure 230 is defined by a bead 237 running in a meandering manner continuously in the central sill region of the sill flange F.

[0070] The meandering path of the bead 237, also in the variant of FIG. 5, both in longitudinal section and in side view results in an undulating contour, respectively an undulating path. Along the longitudinal extension direction L successive upper partial regions 237a of the continuous bead 237 alternate with interposed intermediate regions 235—and trapezoidal in side view here—whilst at the same time lower partial regions 237b of the continuous bead 237 offset thereto alternate with non-protruding intermediate regions 236.

[0071] An undulating structure 230 on the flange section 23 of the door module 2, for example corresponding to FIGS. 4A-4B and 5, may also be provided in a door shell construction T corresponding to the variant of FIGS. 1 to 3C, since a uniform wall thickness over the sill flange F, with at the same time an improvement in the stiffness of the sill region, may be implemented in a simple manner thereby.

However, it should be understood that the use of these terms is for illustrative purposes only with respect to one embodiment. And, use of reference numbers correlating a certain term that is both illustrated in the Figures and present in the claims is not intended to limit the claims to only cover the illustrated embodiment.
