  By the way, the ornament is not limited to a flat plate disclosed in the above-mentioned Patent Document 1, and may have an unevenness that integrally includes an armrest part that forms a part of an armrest provided in a door trim, for example. . In an ornament having such an armrest portion, it is necessary to affix the epidermis following the irregular shape of the ornament base material. At this time, as will be described below, a portion having a small thickness may occur in the epidermis.

  As shown in FIG. 7, when forming the ornament 110 integrally having the armrest portion 130, first, the epidermis 114 is attached to the two attachment portions 112 a and 112 b sandwiching the bent portions 110 a and 110 b of the armrest portion 130. Affixed to the ornament substrate 116. At this time, the outer skin 114 between the sticking portions 112a and 112b has a planar shape and faces the bent portion 110a.

  Next, the epidermis 114 between the sticking portions 112a and 112b is brought closer to the bent portion 110a (in the direction indicated by the arrow in the figure). At this time, it is necessary to bend the skin 114 into a shape that follows the armrest portion 130, that is, a shape that follows the bent portions 110a and 110b. However, since the epidermis 114 is already pasted by the pasting portions 112a and 112b sandwiching the bent portions 110a and 110b, the portion between them is pasted to the ornament base material 116 while being stretched. Therefore, in the armrest part 130 (especially the upper surface 130a of the armrest part 130), since the tensile stress acts on the skin 114, the thickness of the skin 114 tends to be smaller than other parts.

  As shown in FIG. 8, in the vehicle door trim 100 in which the ornament 110 described above is attached to the trim board 120, a gap S is generated between the ornament 110 and the trim board 120. Hereinafter, the cause of the gap S will be described in detail with reference to FIG.

  FIG. 9 is a cross-sectional view taken along line AA in FIG. 8 and shows the boundary between the ornament 110 and the trim board 120. As described above, the ornament 110 integrally includes the armrest portion 130. The upper surface 130a of the armrest part 130 is substantially horizontal.

  As shown in FIG. 9, an outer skin 114 is affixed to the upper surface 130 a of the armrest portion 130. As described above, since the tensile stress acts on the skin 114, the thickness of the skin 114 interposed at the boundary between the ornament 110 and the trim board 120 is smaller than the thickness of other portions. As a result, a gap S is generated between the ornament 110 and the trim board 120 that cannot be generated if the skin 114 has the original thickness. When such a gap S is generated, the continuity of the design surface (vehicle interior side surface) of the vehicle door trim 100 is lost, and the aesthetic appearance is impaired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle door trim that can prevent a gap from being generated between an ornament and a trim board.

  In order to solve the above-mentioned problems, a vehicle door trim according to the present invention is a vehicle door trim in which a decorative ornament is attached to a trim board, and the ornament includes an ornament base material and a vehicle of the ornament base material. A skin attached to the interior side surface, and the ornament base material has a gap between the trim board and the ornament by elastically deforming at a position facing the trim board via the skin. A gap generation preventing means for preventing the occurrence of the gap is provided.

  According to such a configuration, since the gap generation preventing means that can be elastically deformed is provided at a position facing the trim board of the ornament base material, for example, even when the thickness of the skin becomes smaller than the design value, It is possible to prevent a gap from being generated between the trim board and the ornament.

  The gap generation preventing means includes an elastically deformable elastically deformable portion and a base material deflecting portion extending from the elastically deformable portion, and the base material deflecting portion is caused by the elastic deformation of the elastic deformable portion. The distance between the trim board and the trim board can be changed.

  According to such a structure, the distance between the said base material bending part and a trim board can be changed because a base material bending part bends with the elastic deformation of an elastic deformation part. Thereby, it is possible to prevent a gap from being generated between the trim board and the ornament.

The gap generation preventing means may be formed integrally with the ornament base material.
According to such a configuration, it is not necessary to provide the gap generation preventing means separately from the ornament base material, and the number of parts does not increase.

  Further, the ornament base material has an armrest portion that protrudes toward the vehicle interior side, and the gap generation preventing means is an end of at least one of the end portions on the vehicle front side and the vehicle rear side of the armrest portion. It can be provided in the part.

  Thus, when the ornament base material has the armrest portion, the armrest portion extends to the vehicle interior side, so that the skin is stretched on the upper surface of the armrest portion. For this reason, the thickness tends to become particularly small at the end portion on the vehicle front side and the end portion on the vehicle rear side of the armrest portion by extending the skin. Therefore, by providing the gap generation preventing means at at least one of the end portion on the vehicle front side and the end portion on the vehicle rear side of the armrest portion, the effect of preventing the gap generation between the trim board and the ornament. Can be exhibited more effectively.

  ADVANTAGE OF THE INVENTION According to this invention, a clearance gap does not generate | occur | produce between an ornament part and a trim board, but the vehicle door trim provided with the high designability can be provided.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is an exploded perspective view showing a schematic configuration of a vehicle door trim 10 according to the present embodiment. As shown in FIG. 1, the vehicle door trim 10 includes a trim board 12 and an ornament 14 attached to the trim board 12.

The armrest portion 20 is formed so as to project to the vehicle interior side. 1 is the vehicle front side, and the upper right side is the vehicle rear side.

  The trim board 12 is a member constituting the main body of the vehicle door trim 10 and is integrally formed of synthetic resin. The trim board 12 has an opening 12a for attaching the ornament 14 from the back side. In the state where the ornament 14 is attached to the opening 12a, the opening 12a is closed, and the surface of the ornament 14 (the surface on the vehicle interior side) and the surface of the trim board 12 (the surface on the vehicle interior side) are substantially flush. It becomes.

  Note that the trim board 12 may be integrally formed of synthetic resin, or may be configured of a plurality of members. For example, the trim board 12 may be composed of two members arranged one above the other. In this case, the upper member is generally called an upper board and the lower member is called a lower board.

  FIG. 2 is an exploded perspective view showing a schematic configuration of the ornament 14. As shown in FIG. 2, the ornament 14 includes an ornament base material 22 and a skin 24 attached to a surface of the ornament base material 22 on the vehicle interior side.

  The ornament base material 22 is integrally formed of a synthetic resin and has a bulging portion at the center. This bulging portion is composed of a main surface portion 22a that closes the opening 12a of the trim board 12, and a side surface portion 22b that is bent substantially at a right angle from the outer edge of the main surface portion 22a. Further, a thin plate-like attachment portion 22c projects from the outer edge of the side surface portion 22b. The attachment portion 22c is a part for attaching the ornament 14 to the trim board 12, and is fixed to the back surface (surface outside the passenger compartment) of the trim board 12 by screw tightening, heat caulking or the like (not shown).

  The ornament base material 22 is bent at a substantially right angle toward the vehicle interior side and further bent at a tip at a substantially right angle to constitute the armrest portion 20. The side surface portion 22b of the ornament base material 22 constituting the armrest portion 20 is provided with a gap generation preventing means 28 described in detail later. As shown in FIG. 2, the gap generation preventing means 28 is provided at an end portion on the vehicle front side of the armrest portion 20 and an end portion on the vehicle rear side, respectively.

  On the other hand, the skin 24 is bonded to the main surface portion 22a and the side surface portion 22b of the ornament base material 22 with an adhesive or the like. The skin 24 is formed of leather, woven fabric, non-woven fabric, resin sheet, or the like, or a back surface of which a cushioning material is attached, and is attached following the shape of the ornament base material 22. The skin 24 constitutes a design surface on the vehicle interior side of the ornament 14.

  FIG. 3 is an enlarged perspective view of a main part of the ornament base material 22. As shown in FIG. 3, a gap generation preventing means 28 for preventing a gap from being generated between the trim board 12 and the ornament 14 is provided on the side surface portion 22 b of the ornament base material 22 constituting the armrest portion 20. Is provided. The gap generation preventing means 28 is formed integrally with the ornament base material 22 and is formed in a form in which the ornament base material 22 is cut out.

  Next, the mode at the time of attaching the ornament 14 with respect to the trim board 12 is demonstrated using FIG.4 and FIG.5. FIG. 4 is a cross-sectional view showing a state before the ornament 14 is attached to the trim board 12, and FIG. 5 is a cross-sectional view showing a state after the ornament 14 is attached to the trim board 12.

  As shown in FIG. 4, the ornament 14 is attached to the opening 12 a of the trim board 12 from the outside of the passenger compartment (the lower side in FIG. 4). Here, the ornament base material 22 is provided with a gap generation preventing means 28 on a side surface portion 22 b facing the trim board 12 through the skin 24.

  The gap generation preventing unit 28 includes an elastically deformable portion 30 that can be elastically deformed, and a base material bending portion 32 that extends from the elastically deformable portion 30 along the side surface portion 22 b of the ornament base material 22. The elastic deformation portion 30 is a portion where a portion of the ornament base material 22 is thinned, and the thin portion extends along the boundary between the main surface portion 22a and the side surface portion 22b. Thus, since the elastic deformation part 30 has a thin part and rigidity is comparatively small, it can elastically deform along the said thin part.

  The base material bending portion 32 is a rectangular portion in plan view, and the upper end portion thereof is connected to the ornament base material 22 via the elastic deformation portion 30. The base material bending portion 32 can be bent (oscillate) in a direction (left-right direction in FIG. 4) in which the distance from the trim board 12 is changed in accordance with the elastic deformation of the elastic deformation portion 30. ing.

  When the ornament 14 is brought closer to the trim board 12, first, the end 12 b of the trim board 12 comes into contact with the skin 24 of the ornament 14. Here, a tapered surface 12 c for facilitating the attachment of the ornament base material 22 to the trim board 12 is formed at the end 12 b of the trim board 12.

  When the ornament 14 is further brought closer to the trim board 12, the end 12 b of the trim board 12 presses the base material bending portion 32 through the skin 24. Then, as shown in FIG. 5, the elastic deformation part 30 elastically deforms. Accordingly, the base material bending portion 32 swings in a direction away from the end 12b of the trim board 12 (right direction in FIG. 4) with the elastic deformation portion 30 as a swing center. As a result, the ornament 14 is attached in a state where the peripheral edge thereof is in close contact with the opening 12 a of the trim board 12.

According to the vehicle door trim 10 of the present embodiment, even when the thickness is reduced by extending the skin 24, a gap is prevented from being generated between the trim board 12 and the ornament 14. can do. This is because the ornament base material 22 is prevented from generating a gap between the trim board 12 and the ornament 14 by elastic deformation at a position facing the trim board 12 through the skin 24. This is because 28 is provided.
Further, for example, by changing the type of the skin 24, it is possible to prevent a gap from being generated between the trim board 12 and the ornament 14 even when the thickness of the skin 24 is reduced.
Furthermore, even if the size of the space between the ornament base material 22 and the trim board 12 varies due to variations in dimensions after the molding of the ornament base material 22 and the trim board 12, the trim board 12 and the ornament 14 It is possible to prevent a gap from being generated.

Further, according to the vehicle door trim 10 of the present embodiment, the gap generation preventing means 28 changes the distance between the elastically deformable elastic part 30 that is elastically deformable and the trim board 12 as the elastically deformable part 30 is elastically deformed. It has the base material bending part 32 which bends in the direction made to make.
According to such a configuration, the distance between the base material bending portion 32 and the trim board 12 can be changed by the base material bending portion 32 being bent along with the elastic deformation of the elastic deformation portion 30. . Thereby, it is possible to prevent a gap from being generated between the trim board 12 and the ornament 14.

  In addition, according to the vehicle door trim 10 of the present embodiment, the gap generation preventing means 28 is formed integrally with the ornament base material 22, and therefore it is necessary to provide the gap generation prevention means 28 separately from the ornament base material 22. There is no increase in the number of parts.

Further, according to the vehicle door trim 10 of the present embodiment, the ornament base material 22 has the armrest portion 20 so as to project toward the vehicle interior side, and the vehicle front side end portion of the armrest portion 20 and the vehicle rear side. A gap generation preventing means 28 is provided at the end on the side.
As described above, when the ornament base material 22 has the armrest portion 20 integrally, a plurality of bent portions constituting the overhang of the armrest portion 20 to the vehicle interior side are provided. On the other hand, the epidermis 24 is stuck in a stretched state. In particular, the skin 24 is pulled also in the front-rear direction of the vehicle at the end portion on the vehicle front side and the end portion on the vehicle rear side of the armrest portion 20. For this reason, the thickness of the skin 24 is likely to be further reduced at the vehicle front side end portion and the vehicle rear side end portion of the armrest portion 20. Therefore, by providing the gap generation preventing means 28 at the end portion on the vehicle front side and the end portion on the vehicle rear side of the armrest portion 20, it is more sure that a gap is generated between the trim board 12 and the ornament 14. Can be prevented.

Moreover, the lower end portion of the base material bending portion 42 and the side surface portion 22b of the ornament base material 22 may be connected. That is, the gap generation preventing means 40 may be configured by the base flexure portion 42 that is thinned as a whole. Thus, the base material bending part 42 can be favorably bent with the elastic deformation of the elastic deformation part 30 because the base material bending part 42 is thinned.

(2) In the above embodiment, an example in which the gap generation prevention means 28 is provided at the vehicle front side end portion and the vehicle rear side end portion of the armrest portion 20 has been described. However, a gap is generated only at one of the end portions. Prevention means 28 may be provided. Even in this case, the generation of a gap between the trim board 12 and the ornament 14 can be more reliably prevented.
