Most of the door pockets mentioned above are large types that are installed in the lower part of the vehicle door in the front and back direction and can accommodate maps, pamphlets, etc. However, there is a demand for relatively small door pockets that allow for easy viewing of the interior.

However, when providing multiple door pockets on the door trim, multiple pocket boards are required on the trim board to correspond to each opening, which makes the installation process complicated, and it is necessary to prevent adjacent mounting parts from overlapping each other. Design constraints arise, such as the presence of

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vehicle interior material that has a small number of parts and is easy to assemble even when a plurality of openings are provided in the vehicle interior material. The purpose is to

The present invention, which has been made to solve the above-mentioned problems, includes a first member having a design surface facing toward the inside of the vehicle interior and an opening penetrating inside and outside the vehicle interior, and a shape that covers the opening from the opposite side of the design surface. a second member disposed in the opening, the opening includes a first opening and a second opening spaced apart from each other, and the second member includes a first covering portion that covers the first opening; , a vehicle interior material comprising: a second covering part that covers the second opening; and a connecting part that integrally connects the first covering part and the second covering part.

According to the above configuration, the number of parts can be reduced compared to a configuration in which each of the plurality of openings provided in the first member is covered with an individual member. Furthermore, since the number of parts is small, workability when attaching the second member to the first member is improved.

In addition, when a plurality of openings are provided in the first member, there is a concern that the rigidity of the first member may be reduced. Since the connecting portion of the second member is disposed in a portion between the first opening and the second opening, which is likely to be damaged, a decrease in rigidity of the vehicle interior material as a whole is suppressed.

The connecting portion may have a bent portion bent in a direction intersecting the direction of alignment of the first covering portion and the second covering portion while being expandable and contractible in the direction of alignment of the first covering portion and the second covering portion.

According to such a configuration, when the first covering part and the second covering part of the second member are attached based on the peripheries of the first opening and the second opening of the first member, respectively, the first covering part Even if there are tolerances in the distance or angle between the first opening and the second opening between the second covering part (connecting part), these tolerances can be absorbed by the expansion and contraction of the bending part.

One of the bent portions may include a first portion and a second portion extending in mutually different directions.

According to such a configuration, when the first opening (first covering part) and the second opening (second covering part) are arranged in a twisted manner in the space, the first opening (first covering part) and the second opening (second covering part) are arranged in a twisted manner in the space. The elongated first and second portions facilitate absorbing distortions due to tolerances in multiple directions and reduce stress on the second member.

Furthermore, a plurality of the bent portions may be provided in the direction in which the first covering portion and the second covering portion are lined up, and the plurality of bent portions may extend in mutually different directions.

Even with such a configuration, when the first opening (first covering part) and the second opening (second covering part) are arranged in a twisted manner in space, the plurality of bent parts extending in different directions can Distortion due to tolerances can be easily absorbed in a plurality of directions, and stress applied to the second member can be reduced.

The plurality of bent portions may include a pair of bent portions that are bent so as to protrude from a plate surface of the connecting portion in mutually different directions.

According to such a configuration, compared to a configuration in which the plurality of bent portions are bent so as to protrude in the same direction from the plate surface of the connecting portion, distortion due to tolerances can be more easily absorbed, and the second member Such stress can be reduced.

The bent portion is provided on at least one of a first edge that is an edge along the first covering portion and a second edge that is an edge along the second covering portion of the connecting portion. You can.

According to such a configuration, when the first opening (first edge) and the second opening (second edge) are arranged in a twisted manner in the space, the bent portion is located outside the edge of the connecting portion. The stress applied to the second member can be further reduced compared to a configuration in which the second member is provided at the position shown in FIG.

The second member may be fastened to the first member at the connecting portion by a fastening portion.

According to such a configuration, compared to a configuration in which the first covering part and the second covering part are provided as separate members, it becomes possible to share the fastening part, and the second A member can be attached to the first member. That is, the workability during installation is excellent. Further, by fastening the first member and the second member to each other at the portion where the connecting portion is arranged, it becomes more difficult for the two members to be misaligned, and the rigidity of the interior material as a whole is improved.

Between the first member and the second member, there is provided a first reference that serves as a reference for the attachment position of the first covering section to the first member, and a mounting position of the second covering section to the first member. A second standard serving as a standard may be provided.

According to such a configuration, when the first covering part and the second covering part of the second member are attached to the first member using the first reference and the second reference as the reference of the attachment position, respectively, Even if there are tolerances in the distances and angles between the first and second members, these tolerances can be absorbed by the expansion and contraction of the bending part provided in the connecting part.

Further, the vehicle interior material is a door trim for a vehicle, and the first covering portion and the second covering portion are recessed from the design surface of the first member toward the outside of the vehicle interior and downward, and are recessed toward the outside of the vehicle interior and downward. It may constitute a pocket.

According to the present invention, even when a plurality of openings are provided in a vehicle interior material, it is possible to provide a vehicle interior material with a small number of parts and excellent assembly workability.

That is, the attachment portion 52 is provided at a position slightly recessed toward the outside of the vehicle interior from the first inner edge portion 51B (see FIG. 3). The central attachment boss 25 (see FIG. 11) inserted through the insertion hole 53 is configured to be fixed to the attachment portion 52 of the connecting portion 50 by, for example, fixing means such as thermal caulking. Note that the only portion of the connecting portion 50 that is fixed to the trim board 11 is the attachment portion 52.

As shown in FIG. 5, a first stretchable portion 55 (an example of a bent portion) is provided throughout the first edge portion 51 excluding the attachment portion 52 and the flange portion 60. As shown in FIG. As shown in FIGS. 6 and 7, the first elastic portion 55 is a bent portion bent in a crank shape from the first edge 51 toward the back side (outside the vehicle interior). Note that in some of the figures, the first elastic portion 55 is shaded to make it easier to understand. The first elastic portion 55 can be deformed by the stress applied when the pocket board 30 is attached to the trim board 11, and by changing its bending angle, the first elastic portion 55 can be deformed in multiple directions in the vehicle longitudinal direction, vehicle width direction, and vertical direction. It is designed to transform.

As shown in FIGS. 3 and 8, a first upper elastic portion 55A (an example of a first portion), which is a portion of the first elastic portion 55 along the first upper edge 51A, extends generally in the vehicle width direction. , and extends so as to be inclined downward toward the center in the vehicle width direction. Further, the first inner elastic portion 55B (an example of the second portion), which is a portion along the first inner edge portion 51B, extends generally in the vertical direction. That is, the first upper stretchable part 55A and the first inner stretchable part 55B extend in directions that intersect with each other. As described above, by extending the first upper telescopic portion 55A and the first inner telescopic portion 55B in different directions, the first telescopic portion 55 as a whole extends in different directions such as the vehicle longitudinal direction, the vehicle width direction, and the vertical direction. , the structure is such that it can be easily deformed in any direction.

On the other hand, the second edge 56 of the connecting portion 50 is a second upper edge extending from the inner end edge of the upper wall portion 46 of the second covering portion 41 on the passenger compartment side to the upper end edge of the second front wall portion 43. 56A, and a second inner edge portion 56B that extends downward from the second upper edge portion 56A in a curved L-shape. The second upper edge portion 56A extends generally in the vehicle width direction, and the second inner edge portion 56B generally extends in the vertical direction. That is, the second upper edge portion 56A and the second inner edge portion 56B extend in directions that intersect with each other (see FIGS. 3, 5, and 8).

Note that the first upper edge 51A and the second upper edge 56A described above both generally extend in the vehicle width direction, but to be more precise, they are not parallel but slightly twisted. Further, the first inner edge portion 51B and the second inner edge portion 56B described above both generally extend in the vertical direction, but to be more precise, they are not parallel but slightly twisted.

The second edge portion 56 is provided with a second stretchable portion 57 (an example of a bent portion). As shown in FIGS. 6 and 7, the second elastic portion 57 is a bent portion bent in a crank shape from the second edge 56 toward the inside of the vehicle interior. Note that in some of the figures, the second stretchable portion 57 is shaded to make it easier to understand. The second elastic portion 57 can be deformed by the stress applied when the pocket board 30 is attached to the trim board 11, and by changing its bending angle, the second elastic portion 57 can be deformed in multiple directions in the vehicle longitudinal direction, vehicle width direction, and vertical direction. It is designed to transform.

As shown in FIGS. 3, 5, and 8, the second upper elastic portion 57A (an example of the first portion), which is the portion of the second elastic portion 57 along the second upper edge 56A, is generally The second inner stretchable portion 57B (an example of the second portion), which extends in the width direction and is a portion along the second inner edge portion 56B, extends generally in the vertical direction. That is, the second upper stretchable part 57A and the second inner stretchable part 57B extend in directions that intersect with each other. As described above, the second upper elastic part 57A and the second inner elastic part 57B extend in different directions, so that the second elastic part 57 as a whole extends in different directions such as the vehicle longitudinal direction, the vehicle width direction, and the vertical direction. , the structure is such that it can be easily deformed in any direction.

The first upper telescopic portion 55A and the second upper telescopic portion 57A described above both generally extend in the vehicle width direction, but to be more precise, they are not parallel but slightly twisted. Further, the first inner elastic portion 55B and the second inner elastic portion 57B described above both extend generally in the vertical direction, but to be more precise, they are not parallel but slightly twisted.

That is, the first upper elastic part 55A, the first inner elastic part 55B of the first elastic part 55, the second upper elastic part 57A, and the second inner elastic part 57B of the second elastic part 57 described above are all different. It extends in the opposite direction. With such a configuration, the connecting portion 50 as a whole is configured to be easily deformed in any of the different directions, such as the vehicle longitudinal direction, the vehicle width direction, and the vertical direction, by these expandable and contractable portions.

In addition, between the first edge 51 and the second edge 56 of the connecting portion 50, while ensuring the area of the above-mentioned mounting portion 52, the depth of the second door pocket 14B in the vehicle width direction is ensured. In order to do this, a bent portion 58 is formed which is bent into a substantially L-shape from the first edge 51 side to the second edge 56 side (see FIGS. 6 and 7).

When attaching the pocket board 30 to the trim board 11, for example, first the first covering portion 31 of the pocket board 30 is brought close to the first opening 17 of the trim board 11. Then, while overlapping the first flange portion 60A on the peripheral edge of the first opening 17, the first attachment boss 23A is inserted into the first insertion hole 61A, and the first locking claw 24A is inserted into the first locking hole 62A. By locking, the first covering portion 31 is aligned with respect to the first opening 17. That is, the first insertion hole 61A and the first attachment boss 23A, the first locking hole 62A and the first locking pawl 24A are for positioning the first covering part 31 with respect to the first opening 17. It is considered as the standard (the first standard).

Next, while overlapping the second flange portion 60B with the peripheral edge of the second opening 18 of the trim board 11, the second attachment boss (not shown) is inserted into the second insertion hole 61B, and the second locking hole 62B is inserted. By inserting and locking the second locking claw 24B, the second covering portion 41 is aligned with the second opening 18. That is, the second insertion hole 61B, the second attachment boss, the second locking hole 62B, and the second locking claw 24B serve as a reference for positioning the second covering portion 41 with respect to the second opening 18. (Second standard).

In this manner, when the first covering part 31 covers the first opening 17 based on the first reference and the second covering part 41 covers the second opening 18 based on the second reference, the pocket board 30 is connected. The portion 50 is overlapped with the trim board side connecting portion 20, and the central attachment boss 25 is inserted into the insertion hole 53.

By the way, during the above-mentioned installation work, due to molding errors of the trim board 11 and the pocket board 30, etc., the distance and angle between the first opening 17 and the second opening 18, and the first covering part 31 and the second covering part 41 may have tolerances. In such a case, after aligning the first covering part 31 with respect to the first opening 17 based on the first reference, the second covering part 41 is aligned with respect to the second opening 18 based on the second reference. It becomes difficult to align the door pocket 14 to the proper position, and if the alignment is forced, distortions and gaps will occur in the door pocket 14.

To solve this problem, the pocket board 30 of the present embodiment is provided with a first elastic part 55 and a second elastic part 57 in the connecting part 50 that connects the first covering part 31 and the second covering part 41. ing. According to such a configuration, when attaching the first covering part 31 and the second covering part 41 to the first opening 17 and the second opening 18 using separate attachment standards (first standard and second standard), Even if there is a tolerance between the trim board 11 and the pocket board 30, the elastic parts 55 and 57 of the connecting part 50 change the bending angle, so that it can be combined in the vehicle longitudinal direction, vehicle width direction, and vertical direction. It deforms to accommodate tolerances. In other words, since it is possible to adjust the distance and angle of the second covering part 41 with respect to the first covering part 31 relatively easily, the distortion of the pocket board 30 and the trim board 11 can be suppressed, and the distortion of the door pocket 14 can be suppressed. It is possible to suppress the occurrence of gaps.

Next, the effects of the door trim 10 of this embodiment will be explained. The door trim 10 of this embodiment has a design surface 11A facing toward the inside of the vehicle interior, and a trim board 11 having a first opening 17 and a second opening 18 that penetrate into and outside the vehicle interior and are spaced apart from each other. A pocket board 30 is arranged to cover the first opening 17 and the second opening 18 from the opposite side of the design surface 11A. It includes a second covering part 41 that covers the opening 18, and a connecting part 50 that integrally connects the first covering part 31 and the second covering part 41.

According to such a configuration, the number of parts can be reduced compared to a configuration in which each of the plurality of openings (first opening 17, second opening 18) provided in the trim board 11 is covered with an individual member. Furthermore, since the number of parts is small, work efficiency when attaching the pocket board 30 to the trim board 11 is improved.

Furthermore, if the trim board 11 is provided with a plurality of openings (the first opening 17 and the second opening 18), there is a concern that the rigidity of the trim board 11 will be reduced. The pocket board 30 is not only covered with the covering parts (first covering part 31, second covering part 41), but also in the trim board side connecting part 20 between the first opening 17 and the second opening 18, which is easily fragile. Since the connecting portions 50 are overlapped, a decrease in rigidity of the door trim 10 as a whole is suppressed.
