Description

[Technical Field]

[0001] The present invention relates to an interior material for a vehicle. [Background technology]

[0002] The following Patent Document 1 describes a vehicle interior material that is attached to the interior side of a vehicle body panel using clips. More specifically, it describes an automobile door trim that is attached to the interior side of an automobile door panel using clips. This door trim has a plurality of clip seats for holding the clips. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-231881 Summary of the Invention [Problem to be solved by the invention]

[0004] The vehicle interior material (automobile door trim) described in Patent Document 1 often has functional parts such as switches and lighting devices arranged on the outside of the vehicle compartment, and the space for installing these functional parts had to be such that they avoided the clip seat described above.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an interior material for a vehicle that allows for improved freedom in arranging functional parts. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle interior material of the present invention comprises: A vehicle interior material that is attached to the interior side of a vehicle panel that constitutes a vehicle body using a clip, a plate-shaped board portion facing the panel; a clip seat provided on the exterior side of the board portion to hold the clip; a functional component fixing portion for fixing a functional component disposed on the outdoor side of the board portion; Equipped with The clip seat is a standing wall portion that rises from the board portion toward the outside of the vehicle compartment and is open in one direction in a cross direction that intersects with the vehicle compartment inside / outside direction; a seat portion extending from a tip of the upright wall portion in the intersecting direction, closing the outer side of the vehicle cabin of the upright wall portion and forming a surface facing the panel, to which the clip is attached; and The functional component fixing portion is formed inside an area surrounded by the upright wall portion and the seat portion.

[0007] The vehicle interior material disclosed in the present application also has a functional component fixing portion for fixing a functional component inside the clip seat, which allows for greater freedom in the position and orientation of the functional component compared to conventional vehicle interior materials in which the functional component fixing portion was provided away from the clip seat. The vehicle interior material disclosed in the present application is not particularly limited and can be used in various vehicle interior materials. The functional component fixed by the functional component fixing portion is also not particularly limited, but because the functional component fixing portion can be positioned close to the fixing position on the body, the vehicle interior material disclosed in the present application is suitable for fixing functional components whose position relative to the body is important.

[0008] In the above configuration, the functional component fixing portion can be configured to fix a lighting device as the functional component, which emits light from the vehicle interior material toward the inside of the vehicle compartment and illuminates a component other than the vehicle interior material.

[0009] In a vehicle interior material having this configuration, the type of functional component is limited to a lighting device that illuminates a location other than the vehicle interior material, for example, a lighting device for indirect lighting. Such lighting devices must be designed to prevent deviation of the illumination position to another location within the vehicle cabin. However, with the vehicle interior material disclosed in the present application, the lighting device can be fixed near the fixing position to the body, thereby preventing deviation of the illumination position.

[0010] In the above configuration, the functional component fixing portion can be a mounting seat having an insertion hole into which a fixing tool for fixing the functional component is inserted, and the seat surface of the mounting seat can be configured to face the one direction.

[0011] In a vehicle interior material of this configuration, the opening direction of the clip seat coincides with the opening direction of the insertion hole for inserting, for example, a screw or crimping member. Therefore, by aligning these directions with the movement direction of the molding die when molding the vehicle interior material, it is possible to simplify the molding of the vehicle interior material.

[0012] In the above configuration, the mounting seat has a cylindrical boss portion having the insertion hole and a reinforcing rib formed around the boss portion to reinforce the boss portion, and the reinforcing rib can be configured to be connected to the vertical wall portion of the clip seat.

[0013] In a vehicle interior material having this configuration, the functional component fixing portion functions to reinforce the clip seat, thereby improving the strength of the clip seat. For example, when the vehicle interior material disclosed in the present application is used, even if a portion of the upright wall portion is cut out in order to configure the functional component to be fixed inside the clip seat, the vehicle interior material having this configuration can ensure the strength of the clip seat. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide an interior material for a vehicle that allows for improved freedom in arranging functional parts. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] As an embodiment of the vehicle interior material according to the present invention, an interior material used in a vehicle (automobile) will be exemplified. First, before describing the vehicle interior material of this embodiment, a vehicle 10 employing the vehicle interior material will be described. As shown in FIG. 1 , the vehicle 10 has a box-shaped body 12 that is relatively large in the longitudinal and vertical directions, and is capable of transporting a large number of passengers in a passenger compartment (vehicle compartment) 14, which is the interior space of the body 12. A plurality of seats are provided in the passenger compartment 14, some of which seats 16 are disposed above rear wheels 18. The vehicle 10 has an upper floor 24 formed at a position higher than a floor 22 at the rear side of the passenger compartment 14, where passengers board through a boarding door 20. The seat 16 is provided on the upper floor 24. A step 26 is provided for ascending and descending from the floor 22 to the upper floor 24, and a lighting device 28 (see FIG. 3 ) is provided to clearly indicate the position of the step 26.

[0017] As shown in FIG. 2 , this step 26 is provided in the center in the vehicle width direction. Specifically, the front end side of the floor surface material 25, which is the main component of the upper floor 24, is covered with a wall surface material 30 that forms a wall surface 30a facing forward, and the step 26 is provided in the center of the wall surface material 30. The wall surface material 30 has a shape that bulges forward at its center, and the height of a central portion 34 is lower than both end portions 32 in the vehicle width direction. A step member 36 that is parallel to the floor surface 22a of the floor 22 is disposed above the central portion 34. In other words, the wall surface material 30 and the step member 36 form the step 26, and the step 26 has a curved shape that bulges at the center in the vehicle width direction in a plan view. The central portion 34 of the wall surface material 30 forms the side wall surface of the step 26.

[0018] As shown in FIG. 3 , the wall material 30 includes a wall surface 40 that forms a wall surface 30a that is substantially perpendicular to the floor surface 22a of the floor 22, and an inclined surface 42 that extends continuously from the lower end of the wall surface 40 and gradually moves away from the wall surface 30a. In other words, the step 26 has a shape that protrudes forward even when viewed from the side. The lighting device 28 is provided on the inclined surface 42 of the wall material 30 and illuminates the floor surface 22a below the inclined surface 42, thereby illuminating the area around the step 26 and clearly indicating the location of the step 26 to passengers. The wall material 30 is characterized by a structure for fixing the lighting device 28 as a functional component, and this wall material 30 is the vehicle interior material of this embodiment. The configuration of this wall material 30 will be described in detail below.

[0019] The wall material 30 has a plurality of (eight in this embodiment) clip seats 44 on its back side (the exterior side). The wall material 30 is attached to the body by clips 45 held by the clip seats 44. More specifically, the wall material 30 is attached to a plurality of (four in this embodiment) metal brackets 48 that are fixed to a panel 46 that constitutes the body by bolts 47. These brackets 48 are fixed in an array in the vehicle width direction, each extending in the fore-and-aft direction, and also support the step member 36 on their upper surfaces.

[0020] 3, the multiple clip seats 44 are paired with an upper clip seat 44A extending rearward from the back surface of the wall surface portion 40 and a lower clip seat 44B extending rearward from the lower end of the inclined surface portion 42, and two clips 45 held by the pair of clip seats 44A, 44B are adapted to be attached to one bracket 48. As will be explained in detail later, each clip seat 44 extends rearward, and a clip 45 is attached to its rear end. When attached to the clip seat 44, the clip 45 extends parallel to the floor surface 22a, and the wall surface material 30 can be attached to the body by moving it along the floor surface 22a.

[0021] 4 to 6, the lighting device 28 has a plurality of (five in this embodiment) lighting units 50, each of which is attached to a lighting mounting seat 60 provided on the inclined surface portion 42 of the wall surface material 30. More specifically, the lighting mounting seats 60 are formed between the brackets 48 and on the outer side in the vehicle width direction of the brackets 48 on both side ends located on the outer side in the vehicle width direction with respect to the inclined surface portion 42. In other words, the plurality of lighting units 50 are arranged side by side with intervals between them in the vehicle width direction.

[0022] Each lighting unit 50 has the same structure, and here, the lighting units 50 will be briefly described with reference to Figures 7 and 8. The lighting unit 50 comprises an LED circuit board 52 on which a plurality of LEDs serving as light sources are mounted and spaced apart in the longitudinal direction, a housing member 53 that houses the LED circuit board 52, and connection wiring 54 that is connected to the LED circuit board 52 and extends from the housing member 53. The housing member 53 comprises a lens member 56 that diffuses and emits LED light from a light emission surface 56a, and a cover member 57 that blocks the light and closes the upper opening for inserting the LED circuit board 52. As shown in Figure 8, the light emission surface 56a is generally flat and elongated (rectangular). However, this lighting unit 50 utilizes the same lighting device as that used in lighting devices in other parts of the vehicle 10 and in lighting devices in other vehicles, and the light emitting surface 56a has a slightly curved lower end and an asymmetrical shape (the right side is higher than the left side in Figure 8).

[0023] The lens member 56 has a mounting bracket 56b extending from the surface opposite to the light exit surface 56a for mounting to the wall material 30. The mounting bracket 56b of each lighting unit 50 is attached to the above-mentioned lighting mounting base 60. As shown in FIGS. 4 and 5, the lighting units 50 are disposed inside openings 64, 65, 66, 67, and 68 formed in the inclined surface portion 42 of the wall material 30.

[0024] 9 to 16, a mounting structure for a lighting unit 50 to a wall material 30, which is an interior material for a vehicle according to this embodiment, will be described below. As described above, the wall material 30 has clip seats 44 that hold clips 45 for mounting the wall material 30 to a bracket 48. These clip seats 44 are molded integrally with the wall surface portion 40 and the inclined surface portion 42, which serve as a board portion facing the panel 46, during injection molding of the wall material 30.

[0025] As shown in FIG. 9, the clip seat 44 is box-shaped (arrow-shaped) and open in one direction. Specifically, as shown in FIG. 10, the clip seat 44 includes a vertical wall portion 70 rising from the rear surface (outside the vehicle cabin) of the wall portion 40 or the inclined surface portion 42, a seat portion 72 extending in the one direction from the tip of the vertical wall portion 70, and one or two ribs 74 formed on the inner surface of the vertical wall portion 70 and extending parallel to the seat portion 72 to reinforce the vertical wall portion 70. The seat portion 72 is configured to be positioned approximately perpendicular to the floor surface 22a. When the clip 45 is attached to the seat portion 72, it extends parallel to the floor surface 22a. Furthermore, the lower clip seats 44B rising from the inclined surface portion 42 are all shaped to open upward, as shown in FIG. 9.

[0026] The inclined surface portion 42 is provided with a plurality of lighting mounting seats 60 as functional component fixing portions for fixing the lighting device 28 as a functional component, specifically, each of the lighting units 50 constituting the lighting device 28. The lighting units 50 are attached using screws or thermal caulking. As shown in FIGS. 12 to 14 , the lighting mounting seat 60 includes two mounting bosses 80A, 80B protruding upward and a connector fixing portion 82 provided between the two mounting bosses 80A, 80B. These components are integrally formed with the wall surface portion 40 and the inclined surface portion 42 as a board portion. The mounting bosses 80A, 80B each include a cylindrical boss main body 84 having an insertion hole 84a and a plurality of reinforcing ribs 86 extending radially from the outer circumferential surface of the boss main body 84. The reinforcing ribs 86 are arranged at equal angular intervals, forming a generally cross shape when viewed from above.

[0027] The mounting bracket 56b of the lighting unit 50 is formed with two insertion holes 56c into which the boss main bodies 84 of the mounting bosses 80A and 80B are inserted. When assembling the lighting unit 50, the boss main bodies 84 are inserted into the insertion holes 56c of the mounting bracket 56b (see FIG. 7), and the lighting unit 50 is placed on the reinforcing rib 86. Then, a screw (fixing device) 88 is threaded into the insertion hole 84a of the boss main body 84, whereby the mounting bracket 56b is sandwiched between the head of the screw 88 and the reinforcing rib 86, thereby fixing the lighting unit 50. Note that instead of fastening with the screw 88, fastening with heat may be used. Furthermore, as shown in FIG. 12, the mounting bosses 80A and 80B are formed so that their top surfaces are horizontal (parallel to the floor surface 22a), and when the mounting bracket 56b is attached, the light emitting surface 56a faces diagonally downward. That is, the light exit surfaces 56a of the lighting units 50 form the same angle with respect to the floor surface 22a.

[0028] As shown in FIG. 13 , four of the five lighting mounting seats 60 are arranged to overlap the lower clip seats 44B. Specifically, one mounting boss 80A is formed inside the lower clip seat 44B, more specifically, within the area surrounded by the vertical wall portion 70 and the rib portion 74. With this configuration, as shown in FIGS. 15 and 16 , four of the five lighting units 50 are fixed in a state where they overlap the four lower clip seats 44B when viewed from above. Conventionally, functional component fixing portions for fixing functional components have been provided to avoid the clip seats. In the wall material 30, which is a vehicle interior material of this embodiment, the mounting boss 80A for fixing the lighting unit 50 is also provided inside the lower clip seat 44B. This provides greater flexibility in the position and orientation of functional components compared to conventional vehicle interior materials, making it possible to arrange the lighting unit 50 in the narrow space between two brackets 48.

[0029] In the present vehicle 10, each of the lighting units 50 illuminates the floor surface 22a, which is a different location from the wall surface material 30 to which it is attached, and a single line of light is realized by the multiple lighting units 50. Therefore, misalignment of each lighting unit 50 leads to a deterioration in the design of the realized light. However, according to this embodiment, the mounting boss 80A of the lighting unit 50 is provided inside the clip seat 44B, which is the mounting position to the body, so that misalignment between each lighting unit 50 and misalignment of the illumination position can be suppressed, thereby realizing a line of light with a high design quality.

[0030] Furthermore, as described above, in the wall material 30 according to this embodiment, the opening direction of the lower clip seat 44B and, for example, the opening direction of the insertion hole 84a of the boss main body 84 both face upward and coincide. Therefore, when molding the wall material 30, the opening direction can be made to coincide with the movement direction of the molding die, and the wall material 30 can be molded relatively easily.

[0031] Furthermore, the reinforcing ribs 86 of the mounting boss 80A extend to the inner surface of the vertical wall portion 70, the inner surface of the rib portion 74, and the back surface of the inclined surface portion 42, respectively, and are integrally formed with and connected to them. In other words, the mounting boss 80A itself functions to reinforce the clip seat 44B, improving the strength of the clip seat 44B. Incidentally, as shown in FIG. 10 , because the mounting bracket 56b of the lighting unit 50 is fixed so as to extend from the inside to the outside of the vertical wall portion 70, the base end portion of the opening-side end 70a of the vertical wall portion 70 of the lower clip seat 44B is lower in height than the tip end portion. However, since the reinforcing ribs 86 of the mounting boss 80A are connected to the lowered portion of the vertical wall portion 70 of the present wall surface member 30, sufficient strength is ensured.
