[0003] [Patent Document 1] Japanese Patent Publication No. 2022-159582 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration described in Patent Document 1, the pair of protruding pieces only protrude in a plane, so they have low rigidity, and there is a possibility that the pair of protruding pieces will deform when the roof lining is assembled, resulting in low positioning accuracy of the roof lining.

[0005] In view of the above problems, the present invention has an object to provide a roof lining structure for a vehicle that improves the positioning accuracy of the roof lining. [Means for solving the problem]

[0006] In order to solve the above problem, a typical configuration of the present invention is a roof lining structure for a vehicle comprising a roof lining that forms the passenger compartment side of the vehicle roof and a pillar that is erected adjacent to the corner of the roof lining, wherein the vehicle roof lining structure further comprises a recessed portion formed by the corner of the roof lining being recessed downward, and the recessed portion is characterized by having a first upright wall that forms the inner wall in the vehicle width direction, a second upright wall that is continuous with the first upright wall and forms the inner wall in the vehicle fore-and-aft direction, and a bottom wall that connects the lower end of the first upright wall and the lower end of the second upright wall and abuts the pillar.

[0009] One embodiment of the present invention is a roof lining structure for a vehicle comprising a roof lining that forms the passenger compartment side of the vehicle roof and a pillar that is erected adjacent to the corner of the roof lining, and the vehicle roof lining structure further comprises a recessed portion formed by the corner of the roof lining being recessed downward, and the recessed portion is characterized by having a first upright wall that forms the inner wall in the vehicle width direction, a second upright wall that is continuous with the first upright wall and forms the inner wall in the vehicle fore-and-aft direction, and a bottom wall that connects the lower end of the first upright wall and the lower end of the second upright wall and abuts the pillar.

[0010] According to the present invention, the roof lining has a box-shaped recess formed downward by three walls: a first vertical wall, a second vertical wall, and a bottom wall. This improves the rigidity of the portion of the roof lining that abuts against the pillar, i.e., the bottom wall. This allows the corners of the roof lining to abut against the pillar with high precision, improving the positioning accuracy of the roof lining.

[0011] The bottom wall of the recessed portion preferably abuts against the inner wall of the pillar in the vehicle width direction and extends to the front or rear of the pillar to form a space in front or rear of the pillar and outside the bottom wall in the vehicle width direction.

[0012] The space allows the bottom wall of the recess in the roof lining to slide in the longitudinal direction of the vehicle relative to the inner wall of the pillar in the vehicle width direction. In other words, the space provides a margin for assembling the roof lining, preventing distortion of the roof lining.

[0013] The recessed portion may further have a protrusion that protrudes from the bottom wall outward in the vehicle width direction into the space.

[0014] With this configuration, the protrusion is positioned on the front or rear side of the pillar, so the protrusion can be used as a guide when placing the roof lining inside the pillar, making it easy to position the roof lining, and preventing the appearance of the joint between the roof lining and the pillar from being impaired.

[0015] The bottom wall and the protruding portion of the recessed portion may be inclined so as to rise toward the outside in the vehicle width direction, and the first standing wall of the recessed portion may be inclined so as to fall toward the outside in the vehicle width direction.

[0016] With this configuration, the first standing wall and the bottom wall have a cross-sectional shape that is convex downward, which increases the rigidity of the portion that abuts against the pillar, i.e., the bottom wall of the recessed portion, and further improves the positioning accuracy of the roof lining. [Example]

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0018] Fig. 1 is a perspective view of a vehicle roof lining structure 100 according to an embodiment of the present invention, as seen from diagonally above and behind. Fig. 2 is a perspective view of the vehicle roof lining structure 100 of Fig. 1, as seen from inside the vehicle. Fig. 2 is a perspective view of the vehicle roof lining structure 100 of Fig. 1, as seen from inside the vehicle. In Fig. 1 and all other drawings, the front-to-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction is indicated by arrows U (Upward) and D (Downward).

[0019] As shown in Figures 1 and 2, the vehicle roof lining structure 100 includes a roof panel 102 that forms the outer side of the vehicle roof, and a roof lining 104 that forms the cabin side of the vehicle roof. The vehicle roof lining structure 100 also includes a rear pillar (C-pillar) 106 that stands adjacent to the corner of the roof lining 104. The roof lining 104 is disposed below the roof panel 102. A pillar trim 107 shown in Figure 2 is disposed on the cabin side of the rear pillar 106.

[0020] Fig. 3 is a plan view of the roof lining 104 of the vehicle roof lining structure 100 of Fig. 1. Fig. 4 is an enlarged plan view of a portion of Fig. 3. Fig. 5 is a perspective view of Fig. 4. The vehicle roof lining structure 100 has a recessed portion 108 formed by a corner of the roof lining 104 being recessed downward.

[0021] As shown in Fig. 3, the recess 108 has a first standing wall 112. As shown in Fig. 4, the first standing wall 112 forms the inner wall in the vehicle width direction among the standing walls extending in the vehicle front-rear direction. The first standing wall 112 is formed in a range from point P at the rear end to point Q in front of the vehicle. In a plan view, the first standing wall 112 is inclined so as to curve slightly inward in the vehicle width direction from point P to point Q.

[0022] 5, the first standing wall 112 faces outward in the vehicle width direction. The first standing wall 112 is inclined downward from the inner side in the vehicle width direction to the outer side in the vehicle width direction.

[0023] 3, the recess 108 has a second standing wall 114. As shown in FIG. 4, the second standing wall 114 is continuous with the front end of the first standing wall 112. The second standing wall 114 forms a wall that is located on the inner side in the vehicle front-rear direction with respect to the first standing wall 112. The second standing wall 114 extends from point Q to point R. The second standing wall 114 extends from point Q, which is the front end of the first standing wall 112 in the vehicle front-rear direction, to point R on the outer side in the vehicle width direction so as to intersect with the first standing wall 112 at an angle of 90° or more and less than 180° in plan view.

[0024] 5, the second standing wall 114 faces outward in the vehicle width direction and toward the rear of the vehicle. The second standing wall 114 is inclined downward from the center of the roof lining 104 to the outside.

[0025] 3, the roof lining 104 has a bottom wall 116. The bottom wall 116 is a wall that connects the lower ends of the first standing wall 112 and the second standing wall 114.

[0026] As shown in FIG. 4, the bottom wall 116 connects the lower end of the first standing wall 112 from point P to point Q to the lower end of the second standing wall 114 from point Q to point S. Point S is located outward in the vehicle width direction from point Q and inward in the vehicle width direction from point R. In a plan view, the outer end of the bottom wall 116 in the vehicle width direction is inclined so as to be positioned more inward in the vehicle width direction as it approaches the front of the vehicle. As shown in FIG. 5, the bottom wall 116 is inclined so as to rise more outward in the vehicle width direction. This bottom wall 116 abuts against the rear pillar 106 (see FIGS. 6 and 7).

[0027] As shown in FIG. 4, the roof lining 104 has a protruding portion 118 that protrudes from the bottom wall 116 outward in the vehicle width direction. As shown in FIG. 5, the protruding portion 118 is inclined so as to rise as it goes outward in the vehicle width direction. The protruding portion 118 also protrudes forward of the front wall 106b of the rear pillar 106 (see FIGS. 6 and 7). The rear end face of the protruding portion 118 and the front wall 106b on the front side of the rear pillar 106 are parallel to each other (see FIGS. 6 and 7). There is a gap between the protruding portion 118 and the front wall 106b. A harness 200 routed inside the rear pillar 106 is fixed to the protruding portion 118 (see FIGS. 7 and 8).

[0028] 6, the rear pillar 106 has an inner wall 106a. The inner wall 106a is provided on the inner side in the vehicle width direction and extends in the front-rear and up-down directions of the vehicle.

[0029] The rear pillar 106 also has a front wall 106b. The front wall 106b is disposed in front of the inner wall 106a in the vehicle, intersects with the inner wall 106a in a plan view, and extends outward in the vehicle width direction and in the vertical direction.

[0030] As shown in FIG. 6, the bottom wall 116 abuts against an inner wall 106a on the inner side of the rear pillar 106 in the vehicle width direction. The bottom wall 116 extends to the front of the rear pillar 106. A space A is formed in front of the rear pillar 106 and on the outer side of the bottom wall 116 in the vehicle width direction. As shown in FIGS. 7 to 9, the harness 200 has wires 202 and 204. The wire 202 passes through the space A, runs over the protrusion 118 and the bottom wall 116, and is fixed to the second standing wall 114 with tape 206 and to the roof lining 104 with tape 208. The wire 204 passes through the space A and is fixed to the roof lining 104 together with the wire 202 with tape 208.

[0031] Next, a description will be given of the manufacturing process of the vehicle roof lining structure 100. When the roof lining 104 and the recessed portion 108 are assembled to the vehicle body, the protruding portion 118 of the recessed portion 108 comes into contact with the front wall 106b of the rear pillar 106 and is guided to fit within the space A in front of the front wall 106b. The outer end face of the bottom wall 116 in the vehicle width direction comes into contact with the inner wall 106a of the rear pillar 106, forming a seam.

[0032] According to the configuration of this embodiment, as shown in Fig. 3, the roof lining 104 has a box-shaped recess 108 formed downward and defined by three walls: the first standing wall 112, the second standing wall 114, and the bottom wall 116. This improves the rigidity of the portion of the roof lining 104 that abuts against the rear pillar 106, i.e., the bottom wall 116. This allows the corners of the roof lining 104 to abut against the rear pillar 106 with high precision, improving the positioning accuracy of the roof lining 104.

[0033] Furthermore, since the space A is formed, the bottom wall 116 of the recessed portion 108 of the roof lining 104 can slide in the longitudinal direction of the vehicle relative to the inner side wall 106a on the inner side in the vehicle width direction of the rear pillar 106. In other words, since a margin for assembling the roof lining 104 can be secured by the amount of the space A, distortion of the roof lining 104 can be prevented.

[0034] Furthermore, since the protrusion 118 is disposed on the front side of the rear pillar 106, the protrusion 118 can be used as a guide when the roof lining 104 is disposed inside the rear pillar 106, making it easy to position the roof lining 104. This prevents the joint between the roof lining 104 and the rear pillar 106 from deteriorating in appearance.

[0035] Furthermore, if the harness 200 is fixed to the protrusion 118, the path of the harness 200 can be fixed, which prevents the harness 200 from interfering with the rear pillar 106 and the harness 200 from being pinched between the roof lining 104 and the rear pillar 106. This effect can be more effectively obtained by passing the harness 200 through the space A.

[0036] Figure 9 is a perspective view of the vehicle roof lining structure 100 of Figure 1, seen diagonally from the upper right. As shown in Figure 9, the first standing wall 112 and the bottom wall 116 have a cross-sectional shape that convex downward, which increases the rigidity of the portion that abuts against the rear pillar 106, i.e., the bottom wall 116 of the recessed portion 108, and further improves the positioning accuracy of the roof lining 104. If the harness 200 is fixed to the protruding portion 118, it is possible to prevent the weight of the harness 200 from deteriorating the appearance of the joint between the roof lining 104 and the rear pillar 106.

[0037] Furthermore, because the bottom wall 116 and the protruding portion 118 are inclined upward as they move outward in the vehicle width direction, if the harness 200 is to be wrapped around the protruding portion 118 with tape, a large space can be secured between the ground and the protruding portion 118. This makes it easy to wrap the tape around the protruding portion 118.

[0038] Furthermore, since the first standing wall 112 and the bottom wall 116 are formed in a dogleg shape, the harness 200 can be easily routed along the first standing wall 112 and the bottom wall 116. Therefore, the harness 200 can be easily aligned with the roof lining 104, and the path of the harness 200 is less likely to shift.

[0039] Although the embodiment of the present invention is applied to a rear pillar adjacent to a rear corner of the roof lining, the present invention may also be applied to a front pillar (A-pillar) adjacent to a front corner of the roof lining. Furthermore, the present invention may also be applied to a center pillar (B-pillar) adjacent to a longitudinal edge of the roof lining. When applied to a center pillar, the recessed portion has a first standing wall, a second standing wall at the front end of the first standing wall, a third standing wall at the rear end of the first standing wall, and a bottom wall connecting the lower ends of these first to third standing walls. The outer end of this bottom wall in the vehicle width direction may be abutted against the center pillar.

[0040] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0041] Furthermore, the present invention can be practiced by freely combining inventions described in claims and examples, regardless of the dependent relationships of the claims. [Industrial Applicability]
