Description

[0001] The invention relates to a motor vehicle with a motor vehicle body having door cutouts and with an interior paneling.

[0002] A motor vehicle has a body. The body of a motor vehicle has a floor, an A-pillar, a B-pillar, and door cutouts into which motor vehicle doors are inserted. Particularly in sedans, sedan-like vehicles, or SUVs, door cutouts are positioned on both sides of the motor vehicle in the area of each B-pillar, on either side of the respective B-pillar, in order to place a front door on each side of the motor vehicle, and a rear door in front of or behind the B-pillar, respectively.

[0003] The motor vehicle body defines an interior of the motor vehicle, wherein components of the motor vehicle body in the interior area are covered by an interior panel. The present invention relates to a motor vehicle with an interior panel for covering sections of the door cutouts of the motor vehicle body that face the floor of the motor vehicle body, wherein the door cutouts are delimited or defined by a B-pillar extending in the vertical direction of the motor vehicle and by longitudinal members extending laterally next to the respective B-pillar in the longitudinal direction of the motor vehicle. Interior paneling known from practice has the disadvantage that visually disadvantageous transitions between adjacent panel parts are visible. This is due, among other things, to manufacturing tolerances orAssembly tolerances of the adjacent trim parts of the interior trim can only be inadequately compensated.

[0004] WO 2017 / 103 366 A1 discloses a motor vehicle with an interior panel according to the preamble of claim 1.

[0005] DE 10 2008 039 122 A1, DE 10 2014 110 023 A1 and DE 10 2008 052 966 A1 disclose further interior linings according to the state of the art.

[0006] The object of the invention is to provide a motor vehicle with an interior lining which enables improved lining of sections of door cutouts of the motor vehicle body facing a floor of a motor vehicle body.

[0007] This object is achieved by a motor vehicle according to patent claim 1.

[0008] The interior trim comprises at least a first trim part, a second trim part and a third trim part.

[0009] The first trim part of the interior trim serves to cover a section of a first door cutout facing the vehicle floor, wherein the first trim part has a first trim part section extending in the direction of the respective longitudinal member and a second trim part section extending in the direction of the B-pillar.

[0010] The second trim part of the interior trim serves to cover a section of a second door cutout facing the vehicle floor, wherein the second trim part has a first trim part section extending in the direction of the respective longitudinal member and a second trim part section extending in the direction of the B-pillar, which second trim part section adjoins the second trim part section of the first trim part with or without overlap.

[0011] The third trim part of the interior trim extends in the direction of the B-pillar, serves to cover the same in sections and adjoins, with or without overlap, the second trim part section of the first trim part and the second trim part section of the second trim part.

[0012] The first trim part, second trim part, and third trim part are designed such that, to compensate for tolerances during assembly of the interior trim, the first trim part and the second trim part can be displaced relative to one another in the longitudinal direction. Furthermore, the third trim part and the first and second trim parts can be displaced relative to one another in the vertical direction, and thus in the direction of the B-pillar.

[0013] The interior paneling with at least three paneling parts that can be moved relative to one another allows for particularly advantageous and visually appealing paneling of the interior in the area of the door cutout sections facing the floor of the vehicle body.

[0014] In this case, it is particularly possible to cover a section of the B-pillar facing the floor as well as longitudinal members adjacent to this section of the B-pillar, which run adjacent to the floor of the vehicle body and, together with the B-pillar, delimit the door cutouts in sections.

[0015] Manufacturing tolerances and assembly tolerances can be optimally compensated by the relative movement of at least three trim parts to each other.

[0016] Preferably, the first trim part is U-shaped and has a third trim part section extending vertically and thus in the direction of the A-pillar, wherein the second and third trim part sections are arranged at opposite ends of the first trim part section. Preferably, the second trim part is also U-shaped and has a third trim part section extending vertically and thus in the direction of the C-pillar, wherein the second and third trim part sections are arranged at opposite ends of the second trim part section. With such first and second trim parts, the section of the door cutouts facing the floor can be optimally covered.

[0017] According to an advantageous development of the invention, the first trim part and the second trim part are displaceable relative to one another in the longitudinal direction such that an overlap between the second trim part sections of the first trim part and the second trim part is adjustable. This relative movement allows for a particularly advantageous covering of the door cutouts in the sections facing the floor of the motor vehicle body.For this purpose, guides are preferably formed on one or more segments or edges of the second trim part section of the first trim part facing the second trim part section of the second trim part, as well as on one or more segments or edges of the second trim part section of the second trim part facing the second trim part section of the first trim part, which guides engage with one another and allow a relative movement between the first and second trim parts in the longitudinal direction.

[0018] Such guides are particularly preferred in order to enable the relative displacement between the first trim part and the second trim part in the longitudinal direction, but to exclude it in the vertical direction.

[0019] According to claim 1, according to a first alternative, the third trim part and the first trim part are displaceable relative to one another exclusively in the vertical direction such that, according to the first alternative, an overlap between the third trim part and the second trim part section of the first trim part can be adjusted in the vertical direction. For this purpose, according to the first alternative, guides are formed on the second trim part section of the first trim part on a segment or edge facing the third trim part and on the third trim part, which guides allow relative movement exclusively in the vertical direction.According to claim 1, according to the first alternative, the third trim part and the second trim part are additionally displaceable relative to one another both vertically and longitudinally, such that, according to the first alternative, an overlap between the third trim part and the second trim part section of the second trim part can be adjusted in two directions. For this purpose, according to the first alternative, guides are formed on the second trim part section of the second trim part on a segment or edge facing the third trim part and on the third trim part, which guides allow relative movement in the vertical and longitudinal directions.

[0020] According to claim 1, according to a second alternative, the third trim part and the second trim part are displaceable relative to one another exclusively in the vertical direction such that, according to the second alternative, an overlap between the third trim part and the second trim part section of the second trim part can be adjusted in the vertical direction. For this purpose, according to the second alternative, guides are formed on the second trim part section of the second trim part on a segment or edge facing the third trim part and on the third trim part, which guides allow relative movement exclusively in the vertical direction.According to claim 1, according to the second alternative, the third trim part and the first trim part are additionally displaceable relative to one another both vertically and longitudinally, such that, according to the second alternative, an overlap between the third trim part and the second trim part section of the first trim part can be adjusted in two directions. For this purpose, according to the second alternative, guides are formed on the second trim part section of the first trim part, on a segment or edge facing the third trim part, and on the third trim part, which guides allow relative movement in the vertical and longitudinal directions.

[0021] This displaceability of the third trim part according to the above first alternative and the above second alternative, particularly in combination with the displaceability of the first trim part and the second trim part, allows optimal covering of the sections of the door cutouts facing the floor of the motor vehicle body.

[0022] Preferred developments of the invention will become apparent from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail, without being limited thereto, with reference to the drawings.

[0023] The invention relates to a motor vehicle with a motor vehicle body having door cutouts and with an interior paneling for covering sections of the door cutouts of the motor vehicle body facing a floor of the motor vehicle body.

[0024] Fig. 1 shows a schematic side view of a motor vehicle body 30 in the area of a floor 31 and a B-pillar 34 thereof. Door cutouts 1a and 1b, into which motor vehicle doors can later be inserted, are formed in front of and behind the B-pillar 34. A front door can be inserted into the door cutout 1a and a rear door into the door cutout 1b. These two door cutouts 1a and 1b are, as already mentioned above, separated from one another by the B-pillar 34. The B-pillar 34 therefore delimits the door cutouts 1a and 1b in sections. In a lower section, specifically in a section facing the floor 31, the door cutouts 1a and 1b are delimited by longitudinal members 32, which run in front of the B-pillar 34 in the area of the door section 1a and behind the B-pillar 34 in the area of the door cutout 1b. In a section facing away from the floor 31, the door cutouts 1a, 1b are delimited by a roof structure 33 of the motor vehicle body 30.

[0025] The motor vehicle body 30 is covered in the interior area with an interior panel. The present invention relates to a motor vehicle with an interior panel, with the aid of which, in particular, the Fig. 1 can be optically covered in a particularly advantageous manner in the interior of the motor vehicle, namely the sections 3a, 3b and 4 of the door cutouts 1a and 1b facing the floor 31 of the motor vehicle body 30.

[0026] Fig. 2 and Fig. 3 show highly schematic views of an interior panel for covering these sections 3a, 3b and 4 of the door cutouts 1a and 1b.

[0027] The interior trim has a first trim part 2a, which serves to cover a section 3a of the first door cutout 1a facing the vehicle floor 31. This first trim part 2a has a first trim part section 5a extending in the direction of the respective longitudinal member 32 and a second trim part section 6b extending in the direction of the B-pillar 34.

[0028] Furthermore, the interior trim has a second trim part 2b, which serves to cover the section 3b of the second door cutout 1b facing the vehicle floor 31. The second trim part 2b has a first trim part section 5b extending in the direction of the respective longitudinal member 32 and a second trim part section 6c extending in the direction of the B-pillar 34, which adjoins the second trim part section 6b of the first trim part 2a with or without overlap.

[0029] In addition to the first trim part 2a and the second trim part 2b, the interior trim has a third trim part 8, which corresponds to the trim of section 4 (see Fig. 1) of the door cutouts 1a, 1b and which extends in the direction of the B-pillar 34 and adjoins, with or without overlap, the second trim part section 6b of the first trim part 2a and the second trim part section 6c of the second trim part 2b.

[0030] In Fig. 2 and Fig. Overlap regions 7 and 9a, 9b are shown in Figure 3. Thus, an overlap region 7 is formed between the second trim part sections 6b, 6c of the first trim part 2a and the second trim part 2b. The further overlap regions 9a and 9b are each formed between the third trim part 8 and the second trim part sections 6b and 6c of the first trim part 2a and the second trim part 2b.

[0031] In order to optimally align the trim parts 2a, 2b and 8 during the assembly process of the motor vehicle and to compensate for assembly tolerances and manufacturing tolerances, it is provided that the first trim part 2a and the second trim part 2b are displaceable relative to one another in the x-direction and thus in the longitudinal direction in the direction of the double arrow X. The third trim part 8 is displaceable relative to the first trim part 2a and relative to the second trim part 2b in the direction of the double arrow Z at least in the z-direction and in the vertical direction, wherein the z-direction in the illustrated embodiment (see Fig. 1) is defined as the angle bisector between the lateral edges of the B-pillar 34 and therefore runs essentially in the vertical direction.

[0032] The z-direction or vertical direction is therefore defined as the angle bisector between extensions of the edges of the B-pillar 34, which delimit the door cutouts 1a and 1b in the area of the B-pillar 34.

[0033] How best Fig. 2 and Fig. 3, the first covering part 2a and the second covering part 2b are each U-shaped.

[0034] Both the first fairing part 2a and the second fairing part 2b accordingly have third fairing part sections 6a and 6d, respectively, in addition to the first fairing part sections 5a and 5b, respectively, and in addition to the second fairing part sections 6b and 6c, respectively.

[0035] The third trim part sections 6a, 6d of the trim parts 2a, 2b extend substantially in the vertical direction and thus parallel to the second trim part sections 6b, 6c of the trim parts 2a and 2b, wherein both on the first trim part 2a and on the second trim part 2b the respective second trim part section 6b or 6c and the respective third trim part section 6a or 6d are arranged at different ends of the respective first trim part section 5a or 5b.

[0036] By shifting the first fairing part 2a and the second fairing part 2b in the longitudinal direction in the sense of Fig. 3, the overlap area 7 between the second trim part section 6b of the first trim part 2a and the second trim part section 6c of the second trim part 2b is adjustable.

[0037] For this purpose, on the second trim part section 6b of the first trim part 2a and on the second trim part section 6c of the second trim part 2b, Fig. 2, Fig. Three invisible guides are formed, which engage positively and allow only one-dimensional relative movement in the longitudinal direction (arrow X). These guides can be designed as a tongue-and-groove guide. These guides are each formed on segments or edges of the second trim part sections 6b, 6c of the two trim parts 2a, 2b, which face the respective other trim part 2b, 2a.

[0038] The third trim part 8 and the first and second trim parts 2a, 2b are displaceable relative to one another in the vertical direction such that the overlapping areas 9a, 9b between the third trim part 8 and the second trim part sections 6b, 6c of the first trim part 2a and the second trim part 2b are adjustable. For this purpose, on the second trim part sections 6b, 6c of the two trim parts 2a, 2b and on the third trim part 8, namely on mutually facing segments thereof, Fig. 2, Fig. 3 invisible guides are formed, which interact and allow a defined relative movement. In particular, it is provided that these guides allow a one-dimensional relative movement in the vertical direction (double arrow Z) between the third trim part 8 and one of the trim parts of the first and second trim parts 2a, 2b, for example, the first trim part 2a, and a two-dimensional relative movement in the longitudinal direction (double arrow X) and vertical direction (double arrow Z) between the third trim part 8 and the other of the trim parts of the first and second trim parts 2a, 2b, for example, the second trim part 2b.

[0039] The two for the interior cover of the Fig. The trim parts 2a, 2b provided for the sections 3a, 3b of the door cutouts 1a, 1b shown in Figure 1 are U-shaped in the y-projection—that is, in the side view of the motor vehicle. These trim parts 2a, 2b extend, with their trim part sections 5a, 5b, on the vehicle floor side along the horizontal profile of the door cutout 1a, 1b or the longitudinal members 32, and have the trim part sections 6a, 6b, 6c, 6d at both ends, each of which covers the transition from the horizontal to the vertical door cutout 1a, 1b. The second trim part section 6b of the first trim part 2a and the second trim part section 6c of the second trim part 2b have the overlap 7 or, without overlap 7, create a joint in which vertical flank edges of the trim part sections 6b, 6c are opposite one another.A lower edge of the third trim part 8, which preferably has a shell-like or cup-like cross-section, covers the upper edges of the trim part sections 6b, 6c of the first and second trim parts 2a, 2b in the form of overlaps 9a, 9b. Alternatively, the lower edge of the third trim part 8 forms a joint with the upper edge of the trim part sections 6b, 6c without an overlap.

[0040] The body sections extending along the door cutouts 1a, 1b are subject to manufacturing, assembly, and joining tolerances. This effect affects the trim parts 2a, 2b, 8 in the form of positional tolerances along the door cutouts 1a, 1b, especially since these are also subject to manufacturing tolerances.

[0041] The interior trim provides a tolerance compensation concept that particularly compensates for the positional tolerances acting on the trim parts 2a, 2b, 8 in the x- and z-directions and increases the optical quality of the interior trim. Relative movement in the z-direction is possible between the first trim part 2a and the third trim part 8. Relative movement in the x-direction is possible between the first trim part 2a and the second trim part 2b. Relative movement in the x- and z-direction is possible between the second trim part 2b and the third trim part 8.

[0042] Fig. 4 to 24 show a concrete design of the interior paneling. Fig. 4 to 7 show details of the fairing part section 6b of the fairing part 2a. Fig. 8 to 10 show details of the fairing part section 6c of the fairing part 2b. Fig. 11 to 17 show details of the third fairing part 8. Fig. 18 to 24 each show the interaction of two cladding parts 2a and 2b, 2a and 8 or 2b and 8 or the interaction of all cladding parts 2a, 2b and 8 in the respective overlapping area thereof.

[0043] In the specific design of the interior paneling, Fig. 4 the upper edge of the second trim part section 6b of the first trim part 2a in the area of the overlap 9a is provided with a pocket 10, wherein the pocket 10 is either designed as a U-shaped recess 11 ( Fig. 6, Detail A) is open to the upper edge of the second, here rear, fairing part section 6b of the first, here front, fairing part 2a, or in the form of a projection 12 pointing to section 4 ( Fig. 7, Detail A*) is open to the upper edge of the second trim part section 6b of the first trim part 2a.

[0044] In any case, the pocket 10 has a structural dimension d1 extending in the y-direction or transverse direction as well as lateral flanks 13a, 13b according to detail A ( Fig. 6) or Detail A* ( Fig. 7) which are parallel to each other at a distance h, which run in the z-direction and which widen mirror-symmetrically in the y-direction at an angle α.

[0045] Furthermore, in the flank of the fairing part section 6b of the front fairing part 2a facing the second fairing part 2b, at least two groove-like depressions 14a, 14b with the clear width e and the depth f according to section BB ( Fig. 5) are present, which are accessible from the vehicle interior and run parallel to each other with a distance g in the x-direction.

[0046] The upper edge of the second trim part section 6c of the second trim part 2b is provided on the side facing away from the vehicle interior with a finger-like projection 15 ( Fig. 8). The latter is located in the area of the overlap 9b, has a cover surface 16 arranged parallel to the xz plane on the side facing the vehicle interior, and is characterized in the y-direction by the structural dimension d2.

[0047] On the side of the second trim part section 6c of the second trim part 2b facing away from the vehicle interior, at least two projections 17a, 17b ( Fig. 8) whose external dimensions (Detail D, Fig. 10) each correspond to a cuboid with the height e, the depth f and the length k with k >> e and which are positioned at a distance g from one another and are geometrically designed in such a way that they form a form fit, movable exclusively in the x-direction without play, with the groove-like depressions 14a, 14b of the second covering part section 6b of the first covering part 2a, which run parallel to one another in the x-direction.

[0048] The geometry of the projection 17a, 17b within the cuboid, projected in the y-direction onto the base area of the second trim part section 6c of the second trim part 2b, can be designed in a variety of ways, taking into account the demoulding of the tool segments which preferably have a primary forming effect for the production of the trim parts 2a, 2b, 8, and can, for example, be designed as a unidirectional and parallel slat arrangement or rib package, as a rectangle filled with at least one cross-rib arrangement or as in detail D ( Fig. 10) can be dumbbell-shaped or bone-shaped.

[0049] The third trim part 8 is provided on the side facing away from the vehicle interior with two projections 18, 23 ( Fig. 11). The projection 18 is provided with an end face 19 which is arranged parallel to the xz-plane and according to section G*-G* ( Fig. 14) is preferably plane-parallel to the cover surface 16 of the finger-like projection 15 at the upper edge of the second covering part section 6c of the second covering part 2b, without any spacing.

[0050] Alternatively, the end face 19, which is arranged parallel to the xz-plane and without spacing from the cover surface 16 of the finger-like projection 15 on the upper edge of the second covering part section 6c of the second covering part 2b and is plane-parallel to the opposite end face 19, is located on a projection 20 according to section GG ( Fig. 15), which is constructed like a roof in the y-direction and at the same time contains a receptacle 21 for a connecting element 22, in particular a clip, which generates a prestressing force in the y-direction.

[0051] In this case, the prestressing force-generating connecting element 22 either fixes the third cladding part 8 to the section 4 with the effect that according to section GG ( Fig. 15) the end face 19 of the projection 20 and the cover face 16 of the finger-like projection 15, which has the structural dimension d2, lie plane-parallel to one another at the upper edge of the second trim part section 6c of the second trim part 2b without a gap and at the same time a distance m between the finger-like projection 15 and the section 4 is ensured, or the prestressing force-generating connecting element 22 fixes the third trim part 8 to the section 4 and clamps the finger-like projection 15, which has the structural dimension d2, via its cover face 16 between the end face 19 of the projection 20 and the section 4, so that no distance m is present.

[0052] The projection 23 is placed on the side of the third trim part 8 facing away from the vehicle interior and has, according to section HH ( Fig. 16) in the y-direction the dimension p which is at least as large as the dimension d1 by which the extension of the pocket 10 in the y-direction in the region of the overlap 9a on the second trim part section 6b of the first trim part 2a is characterized.

[0053] In addition, the side flanks 24a, 24b of the projection 23 extend parallel to one another in the z-direction at a distance n, which corresponds at most to the distance h of the lateral flanks 13a, 13b of the pocket 10 at the upper edge of the second trim part section 6b of the first trim part 2a, and widen in the y-direction at an angle β, which is identical to the angle α between the lateral flanks 13a, 13b of the pocket 10, in a mirror-symmetrical manner.

[0054] The lateral flanks 13a, 13b of the pocket 10 and the lateral flanks 24a, 24b of the projection 23 lie plane-parallel to one another without clearance and form a guide in this combination.

[0055] Alternatively, the projection 23 is according to section JJ ( Fig. 17) is designed similar to a truncated pyramid, the cover surface 25 of which, parallel to the xz-plane, is provided with a receptacle 26 for a connecting element 27, in particular a clip, which generates a prestressing force in the y-direction. The prestressing force-generating connecting element 27 either fixes the third cladding part 8 to section 4 with the effect that, according to section JJ ( Fig. 17) the two lateral flanks 13a, 13b of the pocket 10 designed with the construction dimension d1 at the upper edge of the second fairing part section 6b of the first fairing part 2a and the two side flanks 24a, 24b as a lateral surface component of the truncated pyramid-like projection 23 lie plane-parallel to one another without any spacing and at the same time a distance q between the upper edge of the second fairing part section 6b of the first fairing part 2a, in which the pocket 10 is located, and the section 4 is ensured, or the prestressing force-generating connecting element 27 fixes the third fairing part 8 to the section 4 and clamps the upper edge of the second fairing part section 6b of the first fairing part 2a via a positive connection, which is achieved by the plane-parallel support of the lateral flanks 13a, 13b located there of the Pocket 10 on the two side flanks 24a,24b of the truncated pyramid-like projection 23, between a shell segment of the projection 23 on the third cladding part 8 and the section 4, so that no distance q is present.

[0056] The concrete implementation described above takes the following points into account: Firstly, the relative mobility to be ensured in the z-direction between the first fairing part 2a and the third fairing part 8. This is according to Fig. 18, Fig. 19 is ensured by the positive engagement acting in the z-direction between the side flanks 24a, 24b of the projection 23 on the trim part 8 and the lateral flanks 13a, 13b of the pocket 10 on the upper edge of the second trim part section 6b of the first trim part 2a.

[0057] Secondly, the relative mobility to be ensured in the x-direction between the first fairing part 2a and the second fairing part 2b. This is according to Fig. 20, Fig. 21 is ensured by the positive connection between the groove-like depressions 14a, 14b in the flank of the second fairing section 6b of the first fairing part 2a facing the second fairing part 2b and the projections 17a, 17b on the second fairing section 6c of the second fairing part 2b. Under the premise k >> e according to detail D ( Fig. 10), the projections 17a, 17b are precisely guided in the x-direction into the groove-like recesses 14a, 14b, which run parallel to one another in the x-direction. This geometric combination of the first and second trim parts 2a, 2b in the area of the overlap 7, analogous to a guide consisting of at least two tracks, ensures that no angular deviations from the x-direction within the xz-plane occur between the first trim part 2a and the second trim part 2b, which would lead to a non-parallel joint between the opposing trim part sections 6b, 6c on the vehicle interior side, and no positional tolerances occur in the z-direction.

[0058] Thirdly, the relative mobility in the x and z directions between the second fairing part 2b and the third fairing part 8 must be ensured. This is ensured by, as shown in Fig. 22, Fig. 23, the cover surface 16 of the finger-like projection 15 on the upper edge of the second trim part section 6c of the second trim part 2b and the end face 19 of the projection 18 on the third trim part 8 lie plane-parallel to one another in the xz plane without any spacing and, in this state, are displaceable relative to one another in two directions - i.e. in the x and z directions.

[0059] Fig. 24 summarizes the overall geometric constellation between the first trim part 2a, the second trim part 2b and the third trim part 8, which is preferably used for the interior-side trim of the lower section of door cutouts 1a, 1b in the side wall of a motor vehicle body.

[0060] Given that the Fig. 2 and Fig. 3 shown third fairing part section 6d of the second fairing part 2b up to a beltline line - i.e. up to a lower edge of the Fig. 1 recognizable cutout for the non-movable vehicle glazing adjacent to a rear door - can be extended, so that with the second trim part 2b at the same time the Fig. Since sections 3b and 3c outlined in Figure 1 can be covered, the number of components for the interior paneling of sections 3a, 3b and 3c shown in Figure 1 is reduced. This reduces vehicle manufacturing costs.

[0061] The invention can increase the perceived value, i.e. the quality of the joints and the overall visual appearance of the panelling of sections 3a, 3b, 3c visible to the vehicle occupant in the vehicle interior.

[0062] According to Fig. 3, the third trim part 8 can be moved relative to the trim parts 2a, 2b in the z-direction. Consequently, it is possible to transfer the optical effects of the tolerances that occur in the trim of section 4 of the B-pillar into the joint or overlap area 9a, 9b of the Fig. 3, which is located in the footwell of the vehicle interior, which is only slightly illuminated by daylight and is also not directly visible to the vehicle occupants due to its ergonomic inaccessibility.

[0063] The relocation of the tolerance compensation point into the footwell of the vehicle interior allows a visually pleasing joint to be designed between an upper edge of the third trim part 8 and a lower edge of a trim part arranged above the third trim part 8, which joint is characterized by a very small joint dimension and continuous, i.e. jump- and kink-free, courses of body-side seals along the door cutouts 1a, 1b.

[0064] These features have a positive effect on the perceived value because the area between the upper edge of the third trim part 8 and the lower edge of the trim part arranged above the third trim part 8 is in the immediate field of vision, especially of the rear passenger, is illuminated by daylight and can usually even be seen from the exterior side via the door glazing.

[0065] If the contact point between the lower edge of the third trim part 8 and the upper edges of the second trim part sections 6b, 6c of the first and second trim parts 2a, 2b, which can move relative to one another in the z-direction, is designed as an overlap 9b, 9a with a rounded or wedge-shaped chamfered end of the lower edge of the third trim part 8, the additional advantages arise that the extent of the tolerances has no influence on the quality of the joint along the lower edge of the third trim part 8 and that no projections pointing into the vehicle interior, which are perceived as visually disturbing light edges when exposed to light, are created on the trim part sections 6b, 6c of the trim parts 2a, 2b.

[0066] Due to the fact that the covering parts 2a, 2b and the sections 3a, 3b covered by the covering parts 2a, 2b are subject to tolerances, the covering parts 2a, 2b are to be manufactured in accordance with Fig. 3 and Fig. 20 are designed to be displaceable relative to one another in the x-direction. The geometric combination in the form of a guide consisting of at least two tracks, in which the recesses 14a, 14b on the trim part section 6b of the trim part 2a and the projections 17a, 17b on the trim part section 6c of the trim part 2b interact without play in the area of the overlap 7, ensures that no angular deviations from the x-direction within the xz-plane and no positional tolerances in the z-direction occur between the trim part 2a and the trim part 2b. This leads to the optically advantageous result that a vertical joint between the trim parts 2a, 2b is always parallel if the contact area between the trim part section 6b of the trim part 2a and the trim part section 6c of the trim part 2b is oppositely arranged as a butt joint or as in Fig. 24 is designed in a shingle-like manner.

[0067] Furthermore, the U-shaped outline of the trim parts 2a, 2b along the sections 3b, 3a ensures that the optical compensation of the tolerances occurring in the x-direction takes place at the foot of section 4 and thus inconspicuously in the footwell of the vehicle interior, which, as mentioned above, is only slightly illuminated by daylight and, moreover, is not directly visible to the vehicle occupant due to its ergonomic inaccessibility, especially since a safety belt of a front seat potentially covers the joint running vertically in the z-direction between the trim parts 2a, 2b.

[0068] As a result of the above-mentioned points, the invention enables a seamless cladding of the sections 3a, 3b in the top view of the trim parts 2a, 2b, which immediately after opening the vehicle door reveals to the observer as an interior fitting with a high sense of value. Furthermore, the homogeneous surfaces of the trim parts 2a, 2b, which are not jagged by disruptive joints when entering the vehicle, correspond visually coherently with the usually minimally dimensioned joints along decorative elements designed specifically for vehicle enhancement, such as entry panels, which can be embedded flush into the surfaces of the trim parts 2a, 2b opposite the lower edge of the door and become visible as an eye-catcher when opening the vehicle doors.

[0069] Furthermore, the invention provides advantages in the assembly of the trim parts 2a, 2b, 8. The first trim part 2a, which is first fastened to the section 3a, offers a form-fitting pre-positioning option for the second trim part 2b due to the recesses 14a, 14b present in the trim part section 6b.

[0070] The second fairing part 2b is equipped on the second fairing part section 6c with generously dimensioned projections 17a, 17b, which already ensure during their insertion into the corresponding recesses 14a, 14b on the fairing part section 6b of the first fairing part 2a that the second fairing part 2b can be easily plugged in the y-direction onto the first fairing part 2a previously fixed to the section 3a.

[0071] Finally, the lateral flanks 13a, 13b of the pocket 10 on the trim part section 6b of the first trim part 2a fixed to section 3a assume the function of centering when, during the fastening of the third trim part 8 to section 4 in the y-direction, the lateral flanks 24a, 24b on the projection 23 interact in a plane-parallel manner with the lateral flanks 13a, 13b of the pocket 10 on the trim part section 6b of the first trim part 2a. This configuration makes it possible to create a precise joint pattern with the first trim part 2a already during the fixing of the third trim part 8 to section 4, in that the lateral flanks 13a, 13b, 24a, 24b come into flat contact after the assembly process is completed.If the third trim part 8 has a projection 23 with a cover surface 25 which is equipped with the receptacle 26 for the connecting element 27, the centering function of the lateral flanks 13a, 13b of the pocket 10 on the trim part section 6b of the first trim part 2a fastened to the section 3a helps to ensure that the longitudinal axis of the connecting element 27 on the third trim part 8 and the center point of a receiving hole 28 intended for the connecting element 27 in the section 4 are aligned with one another during the pre-positioning of the trim part 8 on the section 4.
