Description

The present invention relates to an interior component for a vehicle that includes a component body and a decorative member that covers the surface of the component body.

A technique related to vehicle interior parts is described in Patent Document 1. The method for manufacturing a door component (interior component) described in Patent Document 1 is a technique for integrating a foam base material 110 and a skin 120, which are the main body of the door component, without using an adhesive. As shown in FIG. 15, the foamed base material 110 is composed of a foamed resin layer 112 and a molten layer 114 laminated on the foamed resin layer 112. Then, the foam base material 110 and the skin 120 are stacked and press-molded by the upper mold 122 and the lower mold 124 at a predetermined temperature, so that the foam base material 110 and the skin 120 are integrated. . As described above, the manufacturing method requires large-scale equipment, which is not preferable in terms of manufacturing costs.

Patent Document 2 describes a technique that integrates a component body and a skin without using an adhesive and is advantageous in terms of cost. As shown in FIG. 16, the technique of Patent Document 2 is a hook-and-loop fastener 130, which is composed of a substrate 134 and a skin 132. A large number of cylindrical protrusions 134p are formed on the substrate 134, and gaps are formed between the protrusions 134p. Similarly, a large number of cylindrical projections 132p are formed on the skin 132, and gaps are formed between the projections 132p. Then, the protrusion 132p of the skin 132 and the gap space fit into the gap space and the protrusion 134p of the substrate 134, respectively, so that the skin 132 is fixed to the substrate 134 due to the frictional force between the protrusion 132p and the protrusion 134p. be done.

Japanese Patent Application Publication No. 2014-046516 JP2014-004207A

However, in the configuration in which the substrate 134 and the skin 132 are fixed by the frictional force between the protrusions 132p and 134p, if a gap is formed between the protrusions 132p and 134p due to heat contraction or the like, the frictional force will decrease and the skin will be removed from the substrate 134. It is also possible that 132 comes off.

The present invention has been made to solve the above-mentioned problems, and the problem to be solved by the present invention is the relative sliding portion between the fitted portion of the component body and the fitted portion of the decorative member. The object of the present invention is to suppress a decrease in the frictional force of the decorative member and make it difficult for the decorative member to come off from the main body of the part.

The above problems are solved by each invention. A first aspect of the invention is an interior part for a vehicle, which includes a main part of the part and a decorative member that covers the surface of the main part of the part, wherein a fitting part is provided on the surface of the main part of the part. The decorative member is provided with a fitting portion capable of fitting with the fitted portion of the component main body, and the fitting portion of the component main body and the fitting portion of the decorative member are provided. When the fitting parts are fitted together, unevenness serving as sliding resistance is formed at a relative sliding portion between the fitting part and the fitting part, which slide relative to each other in the fitting direction.

According to the present invention, when the fitted portion of the component body portion and the fitted portion of the decorative member are fitted together, the fitted portion and the fitted portion slide relative to each other in the fitting direction. The moving parts are formed with irregularities that act as sliding resistance. Therefore, even if a gap occurs between the relative sliding parts of the fitted part of the component body and the fitted part of the decorative member due to heat shrinkage, etc., the unevenness will cause the fitted part and the fitted part to The frictional force between the sliding parts relative to the decorative member becomes difficult to decrease, and the decorative member becomes difficult to come off from the component main body.

According to the second invention, the decorative member is a skin-like member and is made of a material softer than the main body of the part, and the fitted part of the main body of the part and the fitted part of the decorative member are connected to each other. A convex portion is formed on at least one of the relative sliding portions. That is, a convex portion formed at one relative sliding portion contacts the other relative sliding portion, and the convex portion or the other relative sliding portion is deformed, so that the distance between the relative sliding portions is Frictional force can be increased.

According to the third invention, the fitted portion of the component main body is composed of a plurality of protrusions and a gap space surrounded by the plurality of protrusions, and the fitted portion of the decorative member is composed of a plurality of protrusions. It is formed by a protrusion and a gap space surrounded by the plurality of protrusions, and the protrusion and the gap space of the decorative member fit into the gap space and the protrusion of the component body, respectively. Accordingly, the decorative member is held relative to the component main body, and the relative sliding portion between the protrusion of the fitted portion of the component main body and the protrusion of the fitted portion of the decorative member is configured. A convex portion is formed on at least one of the two.

According to the fourth invention, the convex portion is formed in a convex strip shape extending in the circumferential direction on the outer peripheral surface of the protrusion. In this way, since the convex portion is formed in the shape of a convex strip extending in the circumferential direction on the outer circumferential surface of the protrusion, the axial direction of the protrusion between the protrusion of the fitted portion of the component body and the protrusion of the fitted portion of the decorative member is The frictional force at will increase.

According to the fifth invention, the fitted portion of the component body and the fitted portion of the decorative member have a convex portion formed on the outer peripheral surface of each protrusion, and the fitted portion of the component body and the fitting portion of the decorative member are fitted, and the convex portion of the protrusion of the component body and the convex portion of the protrusion of the decorative member are engaged in the axial direction of the protrusion. . Therefore, the frictional force in the axial direction between the protrusion of the fitted portion of the component body and the protrusion of the fitted portion of the decorative member becomes even larger.

According to the present invention, it is possible to suppress a decrease in the frictional force between the relative sliding portions of the fitted portion of the component body and the fitted portion of the decorative member, making it difficult for the decorative member to come off from the component body. .

As shown in FIGS. 5 and 6, the protrusions 31t are protrusions that extend in the circumferential direction and have a triangular cross section, and are arranged, for example, in three pieces, at equal intervals in the height direction (axial direction) of the protrusion main body 31m. It is formed. The protrusion 33 of the skin 210 has the same shape as the protrusion 31 of the outer panel 240, and is composed of a protrusion main body 33m and three protrusions 33t.

As shown in FIGS. 5 and 6, the diameter (diameter) of the projection body 31m of the projection 31 of the outer plate 240 and the diameter of the projection body 33m of the projection 33 of the skin 210 are both set to W. There is. Furthermore, the protrusion size of the protrusion 31t on the protrusion 31 of the outer panel 240 and the protrusion size of the protrusion 31t on the protrusion 33 of the skin 210 are both set to L. Furthermore, the height dimension (protrusion dimension in the axial direction) of the protrusion 31 of the outer panel 240 is set to H1, and the height dimension (protrusion dimension in the axial direction) of the protrusion 33 of the skin 210 is set to H2 (>H1). In this embodiment, for example, H1=about 4 mm, H2=about 4 mm+α (0.1 to 0.2 mm), and W=about 3 mm. Further, L is set to approximately 0.5 mm. Here, the outer panel 240 including the protrusion 31 and the outer skin 210 including the protrusion 33 are molded using, for example, a 3D printer that outputs a three-dimensional three-dimensional object based on 3D CAD data.

Further, the protrusions 31 of the outer panel 240 (the recess portion 245) are pushed into the gap space surrounded by the four protrusions 33 of the skin 210 (the recess covering portion 215). This completes the fitting between the fitted portion of the fitting mechanism 30 (the protrusion 31 of the outer plate 240 and the gap space) and the fitting portion (the protrusion 33 of the skin 210 and the gap space).

As a result, as shown in FIGS. 5 and 6, the convex portion 33t of the protrusion 33 of the skin 210 (indentation covering portion 215) and the convex portion 31t of the protrusion 31 of the outer panel 240 are engaged in the axial direction, and the skin 210 is fixed to the outer plate 240 (recessed portion 245). Next, with tension applied, the upper end 241 of the outer plate 240 of the outer skin 210 is placed over the upper end 251 of the inner plate 250, and as shown in FIG. It is fixed to the upper end 251 of the inner plate 250. This completes the attachment of the skin 210 to the outer panel 240 and inner panel 250 of the door section 24.

Here, as shown in FIG. 7, the protrusions 31 of the outer panel 240 or the protrusions 33 of the outer skin 210 constituting the fitting mechanism 30 may become convex due to heat shrinkage or shape variations due to molding. A gap S may occur between the portion 31t and the protrusion 33 (protrusion main body portion 33m) of the epidermis 210. Even in this state, the protrusion 33t of the protrusion 33 of the outer skin 210 and the protrusion 31t of the protrusion 31 of the outer panel 240 are engaged in the axial direction, so that the protrusion 31 of the outer panel 240 and the protrusion 33 of the outer panel 210 are engaged with each other in the axial direction. The frictional force at the sliding portion relative to the outer panel 240 becomes difficult to decrease, and the skin 210 becomes difficult to come off from the outer panel 240.
