[Effects of the Invention]

[0012] According to the present invention, the inner member can be easily positioned and bonded to the back surface of the outer member in an accurate position. [Brief explanation of the drawing]

[0013] [Figure 1] This is a rear view of a garnish according to one embodiment of the present invention, as seen from the vehicle body side. [Figure 2] This is a view of the back of the outer component of the garnish, as seen from the vehicle body side. [Figure 3] This is a perspective view of the inner component of the garnish, as seen from the vehicle body side. [Figure 4] The diagram shows the assembly process for the garnish. (A) shows the process of engaging the engaging piece of the inner member with the engaging receiving portion of the outer member, and (B) shows the process of bonding the inner member to the outer member via double-sided adhesive tape. [Figure 5] This is a cross-sectional view taken along the VV arrow in Figure 1, showing the outer and inner members bonded together via double-sided adhesive tape. [Modes for carrying out the invention]

[0014] Hereinafter, a garnish (vehicle exterior part; vehicle mounting part) according to one embodiment of the present invention will be described with reference to the drawings. The garnish 1 shown in Figure 1 is attached to a vehicle door (vehicle body) and comprises two resin injection molded products, namely an elongated outer member 10 and an inner member 20 assembled to the back side (inside) of the outer member 10.

[0015] <Outer component configuration> As shown in Figure 2, the front surface 10a of the outer member 10 is provided as a design surface that is exposed to the outside, and protrusions, etc., described later are integrally formed on the back surface 10b. In this embodiment, the outer member 10 is tapered at one end, and on the back surface 10b, the region 10x corresponding to this tapered end is difficult to integrally mold with protrusions, etc., and is therefore a smooth surface.

[0016] On the back surface 10b of the outer member 10, in the area excluding the region 10x described above, a plurality of support protrusions 11 and a plurality of support protrusions 12, each with a different function, are integrally formed at intervals along the longitudinal direction of the outer member 10. A clip seat 11a is formed at the top of the support protrusion 11, and a clip 50 (see Figure 1), described later, is supported on these clip seats 11a. A clamping member (not shown), described later, is supported on the support protrusion 12. Note that although protrusions having other roles are further formed on the back surface 10b of the outer member 10, the description thereof is omitted.

[0017] On the back surface 10b of the outer member 10, an engagement receiving portion 15 is protruding in the vicinity of the above-described region 10x. An engagement hole 15a (see FIG. 5) penetrating in the longitudinal direction of the outer member 10 is formed in the engagement receiving portion 15. The engagement receiving portion 15 also has a role as a support protrusion, and a clip seat 15b is formed at the top thereof. As shown in FIGS. 1 and 5, the clip 50 is supported on the clip seat 15b.

[0018] <Configuration of Inner Member> On the back surface 10b of the outer member 10, an inner member 20 is assembled in a region 10x corresponding to the tapered end portion. As shown in FIG. 3, the inner member 20 has a plate-like joint portion 21 extending in the longitudinal direction of the outer member 10, and an engagement piece portion 23 connected to one end in the longitudinal direction of the joint portion 21 via a thin hinge portion 22 (hinge portion). The thin hinge portion 22 extends linearly in a direction orthogonal to the longitudinal direction of the joint portion 21. The engagement piece portion 23 has an engagement claw 24 protruding from the end on the opposite side to the joint portion 21. The joint portion 21 of the inner member 20 is rotatable with respect to the engagement piece portion 23 via the thin hinge portion 22.

[0019] The front surface 21a of the joint portion 21 of the inner member 20 facing the outer member 10 side has a surface shape corresponding to the region 10x of the back surface 10b of the outer member 10 and is smooth. On the back surface 21b of the joint portion 21 of the inner member 20, a support protrusion 25 having a clip seat 25a at the top, a support protrusion 26 for supporting a clamping member (not shown) described later, a clamping piece portion 27, and a reinforcing rib 28 are integrally formed.

[0020] <Assembly Process of Garnish> Double-sided adhesive tape 30 (adhesive means; shown only in Figure 5) is pre-applied to the front surface 10a of the joint portion 21 of the inner member 20. As shown in Figure 4(A), with the joint portion 21 to which the double-sided adhesive tape 30 is attached separated from the area 10x of the back surface 10b of the outer member 10, the engaging claw 24 at the tip of the inner member 20 is inserted into the engaging hole 15a of the engaging receiving portion 15 of the outer member 10.

[0021] As shown in Figure 5, a protrusion 29 is formed at the base end of the engaging claw 24, projecting in the opposite direction to the engaging claw 24. This protrusion 29 contacts the back surface 10b of the outer member 10, pressing the engaging claw 24 against the upper edge of the engaging hole 15a. The engaging claw 24 also has a width dimension corresponding to the engaging hole 15a. Therefore, the engaging claw 24 can engage with the engaging hole 15a with almost no play, the engaging piece 23 and the thin hinge portion 22 can be reliably positioned in their intended locations, and the rotational trajectory of the joint portion 21 of the inner member 20 is determined almost uniquely.

[0022] Next, the joint portion 21 of the inner member 20 is rotated and pressed against the area 10x on the back surface 10b of the outer member 10, centered on the thin-walled hinge portion 22. As a result, the joint portion 21 of the inner member 20 and the area 10x on the back surface 10b of the outer member 10 are bonded together by the double-sided adhesive tape 30, as shown in Figure 5.

[0023] As described above, the thin hinge portion 22 of the inner member 20 can be positioned and the rotational trajectory of the joint portion 21 can be determined, so that the joint portion 21 can be accurately and reliably bonded to the planned position in the area 10x of the back surface 10b of the outer member 10. When rotating the joint portion 21 toward the outer member 10, the position of the joint portion 21 may be finely adjusted using the insertion points of the engagement hole 15a and the engagement claw 24 as pivot points.

[0024] <Steps for attaching the garnish to the door> The garnish 1 assembled as described above is attached to the vehicle's door panel. Briefly, clips 50 are attached to the clip seats 11a and 15b of the outer member 10 and the clip seat 25a of the inner member 20. In addition, clamping members (not shown) are attached to the support projection 12 of the outer member 10 and the support projection 26 of the inner member 20. The garnish 1 can be attached to the door panel by fitting the clips 50 into the mounting holes of the door panel. The clamping members attached to the support projections 12 and 26 press against the door panel and, in cooperation with the clamping members inside the door, clamp the door panel. The clamping piece 27 clamps the lower flange of the door panel, preventing the garnish from lifting up.

[0025] The present invention is not limited to the above embodiments, and various other configurations are possible. This invention is applicable to garnishes and other exterior parts attached to the vehicle body other than doors, and is also applicable to interior parts.

[0026] In the above embodiment, the inner member occupies a portion of the outer member and plays a role in complementing the mounting structure of the outer member to the vehicle body. However, the inner member may occupy almost the entire area of ​​the outer member and perform the role of the mounting structure to the vehicle body by itself. Alternatively, the inner member may not play a role in the mounting structure to the vehicle body and may only serve to reinforce the outer member.

[0027] In the above embodiment, double-sided adhesive tape was used as the bonding means, but a coated adhesive layer may also be used. When assembling, instead of placing the bonding means such as double-sided adhesive tape on the inner member, the bonding means may be placed on the outer member.

[0028] In the above embodiment, a thin-walled hinge was used as the hinge portion between the joint and the engaging piece, but a hinge portion made of a flexible material or a separate mechanical hinge made of spring material may also be used. [Industrial applicability]

[0029] This invention can be applied to exterior and interior parts of vehicles. [Explanation of Symbols]
