Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, the need to improve the design of the passenger compartment has been increasing. In order to improve the design, a configuration can be considered in which the conventional opening trim is omitted and the flange-shaped portion of the panel material (hereinafter referred to as the flange portion) is covered so as to be wrapped with the pillar garnish from the tip side. However, when trying to attach the pillar garnish to the panel material from the interior side of the vehicle compartment, the flange portion has an undercut shape with respect to the attachment direction, so the outer side of the vehicle compartment of the flange portion cannot be covered. For this reason, an opening trim is required to cover the flange portion, which has not only caused a decrease in design but also been a factor in increasing the number of component types.

[0005] The technology disclosed herein was developed based on the circumstances described above, and aims to provide a mounting structure for vehicle interior materials that is aesthetically pleasing and reduces the number of parts. [Means for solving the problem]

[0006] The technology described herein, completed to solve the above problems, is a mounting structure for interior vehicle material covering the interior side of a vehicle body, wherein the vehicle body has a flange portion that protrudes in a direction along its plate surface, and the interior vehicle material has a first divided body having a first main body portion that covers the interior surface of the vehicle body, and a folded portion at the side end of the first main body portion facing the flange portion that is folded back so as to wrap around the flange portion from the tip side in the direction of its protrusion, and a second divided body having a second main body portion arranged in conjunction with the first main body portion and covering the interior surface of the vehicle body, and a vertical wall rising toward the exterior of the vehicle at the side end of the second main body portion that is not adjacent to the first main body portion, wherein the first divided body is assembled to the vehicle body from the tip side of the flange portion in a direction along the plate surface of the vehicle body, and the second divided body is assembled to the vehicle body from the interior side in a direction intersecting the plate surface of the vehicle body.

[0007] When installing interior materials for vehicles onto a vehicle body from the inside of the vehicle, the flange portion of the vehicle body has an undercut shape in the direction of installation. Therefore, it is not possible to cover the flange portion from its protruding end to the outside of the vehicle interior. To address this problem, as shown in the above configuration, the interior material for vehicles is divided into two parts, a first divided body and a second divided body. The first divided body is assembled to the vehicle body from the end of the flange portion in a direction along the surface of the vehicle body, thereby covering the flange portion with the interior material. Furthermore, the ends of the vehicle body where there are no flange portions can be covered by the vertical walls of the second divided body. As a result, it becomes possible to omit the cover members that were previously used separately from the interior material, improving the design and reducing the number of parts.

[0008] The boundary between the first divided body and the second divided body may be in the shape of a step, with one of the first divided body and the second divided body bent in the direction of the vehicle's interior and exterior.

[0009] With the above configuration, the boundary between the first and second sections becomes less visible to passengers due to the stepped portion. In other words, by utilizing the stepped design, the boundary can be made less visible, thereby enhancing the aesthetic design of the vehicle interior.

[0010] A support portion may be provided inside the folded portion to support the flange portion which is positioned inside the folded portion.

[0011] According to the above configuration, it is possible to suppress rattling of the flange portion located within the folded portion, thereby enabling the entire first divided body to be stably held relative to the vehicle body.

[0012] The flange portion is formed to protrude toward the door opening provided in the vehicle body, and the interior material for the vehicle may be a pillar garnish. [Effects of the Invention]

[0013] The technology disclosed herein provides a mounting structure for interior materials for vehicles that offers excellent design and reduces the number of parts. [Brief explanation of the drawing]

[0014] [Figure 1] A schematic diagram showing the interior of a vehicle according to one embodiment. [Figure 2] Perspective view of the pillar garnish [Figure 3] Cross-sectional view II in Figure 2 [Figure 4] A partially enlarged cross-sectional view showing how to attach the first divided section to the pillar panel. [Figure 5] A partially enlarged cross-sectional view showing how to attach the second divided section to the pillar panel. [Modes for carrying out the invention]

[0015] One embodiment will be described with reference to Figures 1 to 5. In this embodiment, an example of a mounting structure 1 for attaching a pillar garnish (an example of interior material for a vehicle) 30 to the interior side of a pillar panel (an example of a vehicle body) 20 on a pillar 15 provided on the side wall of a vehicle 10 will be described. In each figure, the arrows FR and RR indicate the front and rear of the vehicle, respectively; the arrows UP and DW indicate the top and bottom of the vehicle, respectively; and the arrows IN and OUT indicate the interior (inside the vehicle) side and the exterior (outside the vehicle) side, respectively.

[0016] As shown in Figure 1, the vehicle 10 of this embodiment has a box-shaped body 11 with relatively large dimensions in the front-rear and vertical directions, and is capable of transporting multiple people in the passenger compartment, which is the interior space of the body 11. The vehicle 10 has a door opening 12 and a window opening 13 side by side on its side wall, and these door openings 12 and window openings 13 are separated by a pillar 15. The pillar 15 is a long, slender column extending in the vertical direction.

[0017] The pillar 15 is constructed by attaching a pillar garnish 30 to the interior side of the pillar panel 20. The pillar panel 20 consists of multiple metal panel members and, as shown in Figure 3, comprises a pillar inner panel 21 located on the interior side of the vehicle, a pillar outer panel 23 located on the exterior side of the vehicle, and a reinforcement panel 22 located between them. The front and rear ends of the pillar inner panel 21, reinforcement panel 22, and pillar outer panel 23 overlap and are joined to each other, forming a front flange portion 24 and a rear flange portion 25 that extend in the front-rear direction, generally following the interior surface of the pillar 15.

[0018] Furthermore, the reinforcement panel 22 includes an extension portion 22A that extends further rearward from the rear flange portion 25.

[0019] In addition, between the front flange portion 24 and the rear flange portion 25, the pillar inner panel 21, the reinforcement panel 22, and the pillar outer panel 23 are arranged so as to be separated from each other in the vehicle interior-exterior direction. Specifically, as shown in FIG. 3, the pillar inner panel 21 is configured to extend in the front-rear direction and bend in a crank shape toward the outside of the vehicle at the vicinity of the rear end, and the reinforcement panel 22 is configured to extend in the front-rear direction and bend in a crank shape toward the outside of the vehicle in front of the bent portion of the pillar inner panel 21 and on the vehicle interior side. Further, the pillar outer panel 23 is configured to extend in the front-rear direction and bend in a substantially crank shape toward the outside of the vehicle in front of the bent portion of the reinforcement panel 22 and on the vehicle interior side. With such a configuration, the rear flange portion 25 is arranged relatively outside the vehicle compared to the front flange portion 24.

[0020] On the vehicle interior side of the pillar panel 20, a pillar garnish 30 (an example of a vehicle interior material) is attached. The pillar garnish 30 of the present embodiment is composed of a combination of a first divided body 31 and a second divided body 41 divided along the vertical direction.

[0021] As shown in FIGS. 2 and 3, the first divided body 31 includes a vertically long plate-like first main body portion 32 that covers the front portion of the pillar panel 20 from the vehicle interior side, and at the side end portion (front side end portion) of the first main body portion 32 that faces the front flange portion 24, it has a folded-back portion 33 that curves substantially U-shaped toward the outside of the vehicle and folds back rearward so as to wrap the front flange portion 24 from the tip side (front side) in its protruding direction. Thereby, the front flange portion 24 is arranged inside the substantially U-shaped folded-back portion 33 (see FIG. 4).

[0022] On the inside of the folded portion 33, there are multiple support ribs (an example of support portion) 34 that extend intermittently in the direction of extension (vertical direction) of the folded portion 33 and in a direction that spans the inside of the folded portion 33. As shown in Figure 4, the support ribs 34 have recesses 34A for accommodating the front flange portion 24 inserted into the folded portion 33. By inserting the front flange portion 24 into these recesses 34A from the tip side, rattling in the direction of the vehicle interior and exterior within the folded portion 33 is suppressed.

[0023] Furthermore, the side end of the first main body 32 opposite to the side end where the folded portion 33 is provided (the rear side) is bent into a groove shape that is recessed toward the outside of the vehicle interior. More specifically, as shown in Figure 5, the groove 35 is formed by a front wall portion 36 rising toward the outside of the vehicle interior from the rear side end of the first main body 32, a bottom wall portion 37 extending toward the rear from the end of the front wall portion 36 toward the outside of the vehicle interior, and a rear wall portion 38 rising toward the inside of the vehicle interior from the rear end of the bottom wall portion 37. The edge of the rear wall portion 38 is provided with a plurality of mounting pieces 39 that intermittently protrude toward the rear in the direction of extension of the groove 35 (vertical direction). Mounting holes are formed through each mounting piece 39 (not shown).

[0024] As shown in Figure 3, the first divided body 31 is attached to the pillar panel 20 by bolting the mounting piece 39 to a fixing member 26 provided on the pillar panel 20 side, with the front flange portion 24 positioned inside the folded portion 33 as described above, and the first main body portion 32 covering the front portion of the interior surface of the pillar panel 20.

[0025] On the other hand, as shown in Figures 2 and 3, the second divided body 41 has a roughly L-shaped cross-section, comprising a vertically elongated plate-like second main body 42 that is arranged to connect with the first main body 32 on the rear side of the first divided body 31 and covers the rear portion of the pillar panel 20 from the inside of the vehicle interior, and a rear vertical wall (an example of a vertical wall) 43 that rises from the second main body 42 toward the outside of the vehicle interior at the side end of the second main body 42 that is located on the opposite side (rear side) from the first main body 32, that is, the side end facing the rear flange portion 25. The dimensions of the second main body 42 in the front-rear direction are smaller than the dimensions of the first main body 32 in the front-rear direction.

[0026] The rear vertical wall 43 is positioned further rearward than the rear flange portion 25 and extends beyond the rear flange portion 25 to the outside of the vehicle interior. As a result, the rear flange portion 25 is covered by the second divided body 41 from the inside and rear of the vehicle interior (see Figure 3). The outer surface of the rear vertical wall 43 is provided with ribs 45 that rise from the plate surface and extend in the front-rear direction of the vehicle 10, and a seat surface 46 is formed that rises in a direction intersecting the plate surface of the ribs 45, and a mounting hole 46A that penetrates the plate surface is formed in this seat surface 46.

[0027] Furthermore, the side end of the second main body 42 that is connected to the first main body 32 (the front side end opposite to the side end where the rear vertical wall 43 is provided) is a front vertical wall 44 that rises while being bent in a crank shape toward the outside of the vehicle interior. The tip of this front vertical wall 44 is positioned to face the bottom wall 37 of the first main body 32 as described above. In other words, a groove-shaped groove 35A is formed by the front wall 36 and bottom wall 37 of the first divided body 31 and the front vertical wall 44 of the second divided body 41 (see Figure 5). As a result, when an occupant looks at the pillar garnish 30 from the inside of the vehicle interior, the boundary between the first divided body 31 and the second divided body 41 overlaps with the rising portion of the front vertical wall 44 from the bottom of the groove 35A (the bottom wall 37 of the groove 35), making the boundary difficult to discern, and the first divided body 31 and the second divided body 41 appear to be connected as a single unit.

[0028] Furthermore, this groove 35A is formed to enhance the aesthetic design of the vehicle interior, and the boundary between the first divided body 31 and the second divided body 41 is positioned in a location that is difficult for passengers to discern by utilizing this groove 35A.

[0029] As described above, the second divided body 41 is positioned so that the tip of the front vertical wall 44 faces the bottom wall 37 of the first main body 32, the second main body 42 covers the rear portion of the interior surface of the pillar panel 20, and the rear vertical wall 43 covers the rear flange portion 25 from the rear, and the seat surface 46 is placed on the extension portion 22A of the reinforcement panel 22 extending from the rear flange portion 25 and the clip is fitted, thereby attaching it to the pillar panel 20 (see Figure 3). When the second divided body is attached to the pillar panel 20, the mounting piece 39 of the first divided body 31 is covered from the interior side by the second main body 42.

[0030] In this way, the first divided part 31 and the second divided part 41 are individually attached to the pillar panel 20, so that the pillar garnish 30 as a whole covers the interior surface of the pillar panel 20 and both front and rear ends (front flange portion 24 and rear flange portion 25) of the pillar panel 20, with a space between it and the pillar panel 20. It also covers the exterior surface of the front flange portion 24.

[0031] Next, the effects will be explained. The mounting structure 1 of the pillar garnish 30 in this embodiment includes a pillar panel 20 which has a front flange portion 24 that protrudes in a direction along its surface, and a first divided body 31 which has a first main body portion 32 that covers the interior surface of the pillar panel 20, and a folded portion 33 at the side end of the first main body portion 32 facing the front flange portion 24 that is folded back so as to wrap around the front flange portion 24 from the tip side in the direction of its protrusion, and the pillar panel The pillar panel 20 has a second main body 42 that covers the interior surface of the vehicle, and a second divided body 41 that has a rear vertical wall 43 that rises toward the exterior of the vehicle at the side end of the second main body 42 that is located opposite to the first main body 32. The first divided body 31 is assembled to the pillar panel 20 from the tip side of the front flange portion 24 (front of the vehicle) in a direction along the surface of the pillar panel 20, and the second divided body 41 is assembled to the pillar panel 20 from the interior side in a direction intersecting the surface of the pillar panel 20.

[0032] When the pillar garnish 30 is attached to the pillar panel 20 from the inside of the vehicle, the front flange portion 24 of the pillar panel 20 has an undercut shape with respect to the mounting direction, making it impossible to cover the front flange portion 24 from its protruding end to the outside of the vehicle. To address this problem, as shown in the above configuration, the pillar garnish 30 is divided into two parts, a first divided body 31 and a second divided body 41, and the first divided body 31 is assembled to the pillar panel 20 from the end of the front flange portion 24 in a direction along the surface of the pillar panel 20, thereby covering the front flange portion 24 with the pillar garnish 30. In addition, the rear flange portion 25 of the pillar panel 20, which is located on the opposite side of the front flange portion 24, can be covered by the rear vertical wall 43 of the second divided body 41. Therefore, it becomes possible to omit the cover member that was conventionally used, which is separate from the pillar garnish 30, improving the design and reducing the number of parts.

[0033] Furthermore, the boundary between the first divided body 31 and the second divided body 41 is grooved (groove 35A) by bending the rear end of the first divided body 31 so as to recess it outwards from the passenger compartment and by bending the front end of the second divided body 41 in a crank shape outwards from the passenger compartment and forming a front vertical wall 44.

[0034] According to the above configuration, the boundary between the first divided body 31 and the second divided body 41 becomes less visible to passengers due to the stepped portion. In other words, by utilizing the stepped design, the boundary can be made less visible, thereby enhancing the aesthetic design of the vehicle interior.

[0035] Furthermore, a support rib 34 is provided on the inside of the folded portion 33 to support the front flange portion 24 which is positioned inside the folded portion 33.

[0036] With the above configuration, it is possible to suppress rattling of the front flange portion 24 located within the folded portion 33. Furthermore, in the case of a long interior material (pillar garnish 30) as in this embodiment, manufacturing tolerances and assembly tolerances may be large, but even if such tolerances occur, rattling can be suppressed by the support rib 34. Thus, the entire first divided body 31 can be stably held against the pillar panel 20.

[0037] Furthermore, the front flange portion 24 is a part that protrudes toward the door opening 12 provided in the pillar panel 20. By covering such a portion with the pillar garnish 30 described in this embodiment, the design of the vehicle interior can be enhanced, and the number of parts can be reduced.

[0038] <Other Embodiments> The technologies disclosed herein are not limited to the embodiments described above in the description and drawings, but also include, for example, the following embodiments.

[0039] (1) In the above embodiment, the boundary between the first divided body 31 and the second divided body 41 is shown to be grooved, but the boundary can be made less visible by simply making it a step. Furthermore, a configuration without a step is also included in the technical scope.

[0040] (2) The support rib 34 provided on the inside of the folded portion 33 may be omitted.

[0041] (3) In the above embodiment, a flange portion formed to protrude toward a door opening provided on the vehicle body and a pillar garnish covering this flange portion were shown. However, the interior material for vehicles is not limited to a pillar garnish and can be applied to other interior materials for vehicles that cover a vehicle body having a flange portion.
