Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a mounting structure for a sound-absorbing material in an interior material for a vehicle. [Background technology]

[0002] A known mounting structure for sound-absorbing material in vehicle interior materials is described in the following Patent Document 1. Specifically, the sound-absorbing material has a plurality of holes into which clip bosses (protrusions) provided on the interior material are inserted, and the clip bosses are inserted into these holes to mount the sound-absorbing material to the rear surface of the interior material. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-252125 Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, in a configuration in which holes are provided in the sound-absorbing material to allow the clip bosses to pass through, the holes must be made larger to account for installation tolerances. This means that the sound-absorbing material is prone to movement relative to the interior material before being fixed, raising concerns about misalignment. Furthermore, in a configuration in which holes are provided in the sound-absorbing material, the parts cut out to make the holes are discarded, which increases disposal costs and increases costs.

[0005] The technology disclosed in this specification has been made in consideration of the above circumstances, and aims to provide a mounting structure for sound-absorbing material to vehicle interior materials that is less likely to become misaligned relative to the vehicle interior materials during mounting work and that can reduce processing costs. [Means for solving the problem]

[0006] The technology disclosed in this specification is a mounting structure for sound-absorbing material in a vehicle interior material, wherein the vehicle interior material has a protruding portion that protrudes from its plate surface, the sound-absorbing material is superimposed on the vehicle interior material and has slits that allow a portion of the sound-absorbing material to be cut and raised, the portion surrounded by the slits is a rising portion that rises while being supported by the protruding portion, at least a portion of the protruding portion is flat and forms a flat support portion that supports the rising portion, and the sound-absorbing material is positioned relative to the vehicle interior material by the rising portion being supported by the flat support portion.

[0007] According to the above configuration, the flat support portion of the protruding portion can be used to position the sound-absorbing material relative to the vehicle interior material. Specifically, if the protruding portion has a flat support portion, the worker can simply press the portion surrounded by the slit with the protruding portion to raise it up, and then support the raised upright portion on the flat support portion, thereby positioning and attaching the sound-absorbing material relative to the vehicle interior material.

[0008] More specifically, when a through hole is provided at a position corresponding to the protruding portion of the sound-absorbing material, as in the past, the through hole must be made larger to take into account installation tolerances, which means that the sound-absorbing material is prone to movement relative to the vehicle interior material before being fixed, raising concerns about misalignment. For this reason, it is necessary to provide a positioning mark and carefully align the installation work with the mark. In contrast, with the above-mentioned configuration, misalignment can be suppressed by utilizing the elastic force with which the raised portion of the sound-absorbing material presses against the flat support portion, thereby simplifying the installation work of the sound-absorbing material to the vehicle interior material. Moreover, because the raised portion is positioned over the flat support portion, it is supported over a wide area by the flat support portion, thereby improving the positioning accuracy of the sound-absorbing material relative to the vehicle interior material.

[0009] Furthermore, unlike conventional configurations in which through holes are provided at positions corresponding to the protruding portions of the sound-absorbing material, no waste material is generated, thereby reducing the cost of disposing of waste material.

[0010] The slits may be H-shaped, having a pair of first slits extending parallel to each other and a second slit connecting the pair of first slits at the center in the extension direction of the pair of first slits, and one of the portions of the sound-absorbing material surrounded by the pair of first slits and the second slit may be supported by the flat support portion, and the other may be supported on the opposite side of the flat support portion of the protrusion.

[0011] When the slits are H-shaped as a whole, as in the above configuration, the portion of the sound-absorbing material surrounded by the slits can be made to open on both sides (so-called double doors), and the pair of raised portions can be supported on both sides of the flat support portion of the protruding portion and the opposite side of the flat support portion. With this configuration, the protruding portion can be sandwiched from both sides while utilizing the elastic force of the sound-absorbing material, thereby further suppressing displacement of the sound-absorbing material relative to the vehicle interior material.

[0012] A reinforcing rib is provided on the opposite side of the protruding portion to the flat support portion, rising from the plate surface and protruding radially from the protruding portion, and the other of the portions of the sound-absorbing material surrounded by the pair of first slits and the second slit may be supported by the end surface of the reinforcing rib.

[0013] According to the above configuration, even when the protruding portion is provided with a reinforcing rib, the sound-absorbing material can be easily attached to the interior material of the vehicle without having to position it by providing a notch or the like in the sound-absorbing material to allow the reinforcing rib to escape.

[0014] The vehicle interior material may be elongated, and the first slit may be arranged along the longitudinal direction of the vehicle interior material.

[0015] When a vehicle interior material is long, there is a concern that manufacturing tolerances and positioning tolerances will become large. With the above configuration, the first slits can absorb the longitudinal tolerances, making it easier to position the sound-absorbing material relative to the vehicle interior material.

[0016] The vehicle interior material may have another protruding portion protruding from its plate surface, and the sound-absorbing material may have an escape portion provided at a position corresponding to the other protruding portion to prevent interference between the other protruding portion and the sound-absorbing material.

[0017] According to the above configuration, the sound absorbing material can be positioned relative to the vehicle interior material at two locations, the protruding portion and the other protruding portion, so that rotation of the sound absorbing material relative to the vehicle interior material can be restricted.

[0018] The relief portion may be a notch formed by cutting out a recess from an end portion of the sound absorbing material.

[0019] Furthermore, the vehicle interior material is attached to the inside of an exterior panel that constitutes the exterior of the vehicle, and the protrusion may be a clip seat that engages a clip for attaching the vehicle interior material to the exterior panel. [Effects of the Invention]

[0020] The technology disclosed in this specification makes it possible to provide a mounting structure for a sound-absorbing material to a vehicle interior material that is less likely to become misaligned with the vehicle interior material during mounting work, and that can reduce processing costs. [Brief explanation of the drawings]

[0021] [Figure 1] FIG. 1 is a perspective view showing a structure for attaching a sound-absorbing material to a pillar garnish according to an embodiment; [Figure 2] Partially enlarged perspective view of Figure 1 [Figure 3] Partially enlarged perspective view of Figure 2 [Figure 4] Front view of Figure 2 [Figure 5] Section II of Figure 4 [Figure 6] Plan view of sound-absorbing material DETAILED DESCRIPTION OF THE INVENTION

[0022] One embodiment will be described with reference to Figures 1 to 6. In this embodiment, a pillar garnish 10 for a vehicle is used as an example of a vehicle interior material, and a mounting structure for a sound-absorbing material 30 in the pillar garnish 10 will be described. In the following description, the upper right side of Figure 1 is referred to as the front of the vehicle, the lower left side as the rear of the vehicle, the upper side as the upside, the lower side as the downside, and the lower right side as the outside of the vehicle cabin.

[0023] 1 is a perspective view of the mounting structure of a sound-absorbing material 30 in a pillar garnish 10 according to this embodiment, as viewed from outside the vehicle cabin. As shown in FIGS. 1 and 2, the pillar garnish 10 includes a rectangular plate-shaped main body 11 bent into an L-shaped cross section.

[0024] The main body 11 includes a first wall 12 extending substantially vertically and a second wall 13 bent from the lower end of the first wall 12 toward the outside of the vehicle cabin and extending substantially horizontally. A tapered rearward extending portion 14 extending rearward is provided at the rear end of the first wall 12. A generally rectangular forward extending portion 15 that is long in the front-to-rear direction and extends forward is provided at the front end of the second wall 13. A front mounting portion 16 is provided at the front end of the forward extending portion 15, bent from the forward extending portion 15 and extending substantially parallel to the first wall 12. As described above, the pillar garnish 10 of this embodiment has an elongated shape in the front-to-rear direction as a whole.

[0025] The first wall 12 of the main body 11 is provided with two clip seats 20 lined up in the front-to-rear direction on its exterior surface 12A (the surface facing the exterior panel, an example of a plate surface). These clip seats 20 are pedestals that engage clips 29 for attaching the pillar garnish 10 to the exterior panel, and are of the same shape and size. Hereinafter, the clip seat 20 located at the front will be referred to as a front clip seat 20A (an example of another protrusion), and the clip seat located at the rear will be referred to as a rear clip seat 20B (an example of a protrusion), and when no distinction is made, they will be referred to as clip seats 20.

[0026] Each clip seat 20 is semi-cylindrical. Specifically, as shown in Figures 3 and 5, the clip seat 20 includes a side wall 21 that is curved to have a U-shaped cross section and rises from the first wall 12, and a mounting plate 22 (see Figure 5) that is substantially semi-circular and shaped like a plate and spans the entire tip of the side wall 21 in the rising direction. The side wall 21 rises from the first wall 12 with its opening facing rearward. The mounting plate 22 is formed with a mounting groove 23 for mounting a clip 29.

[0027] The interior of the clip seat 20 is partitioned by a horizontal wall 24 extending substantially parallel to the first wall portion 12 and a vertical wall 25 extending in the front-to-rear direction and perpendicular to the horizontal wall 24. The horizontal wall 24 and the vertical wall 25 are positioned so as not to protrude outward from the opening end 21A of the side wall portion 21 (see FIG. 5).

[0028] Of the two clip seats 20, the rear clip seat 20B, which is disposed on the rear side, is provided with a triangular plate-like reinforcing rib 27 at the center of the outer surface of its side wall portion 21, which rises from the first wall portion 12 and extends radially outward (forward) in the radial direction of the side wall portion 21. Note that this reinforcing rib 27 is not provided on the front clip seat 20A, which is disposed on the front side.

[0029] A plurality of ribs 17 extending in the vertical and longitudinal directions are provided in a mesh pattern on the exterior surface 10A of the passenger compartment of the pillar garnish 10. These ribs 17 have the same height from the first wall portion 12. Furthermore, welding portions 18 for welding the sound-absorbing material 30, which will be described later, are provided on some of the ribs 17 in portions where the sound-absorbing material 30 is to be disposed (see FIG. 3).

[0030] The sound-absorbing material 30 is made by, for example, forming a nonwoven fabric into a felt shape with a certain thickness. The sound-absorbing material 30 is attached to the outer surface 10A of the vehicle interior of the pillar garnish 10, and has an H-shaped slit 31 in a portion corresponding to the portion where the rear clip seat 20B is disposed (see FIG. 6).

[0031] The H-shaped slit 31 is composed of a pair of horizontal slits (an example of a first slit) 32 extending in the front-rear direction, and a vertical slit (an example of a second slit) 33 connecting the approximate center portions of the pair of horizontal slits 32. In other words, the H-shaped slit 31 is a slit in which the horizontal slit 32 and the vertical slit 33 are arranged to form an H shape.

[0032] In detail, when the sound-absorbing material 30 is placed at a predetermined position on the outer surface 10A of the vehicle interior of the pillar garnish 10, the pair of horizontal slits 32 are set so as to contact the upper and lower ends of the rear clip seat 20B or to be positioned slightly away from the upper and lower ends (see Figure 4).

[0033] On the other hand, the vertical slit 33 is set to be disposed at a position that roughly divides the rear clip seat 20B in two when the sound-absorbing material 30 is disposed at a predetermined position on the outer surface 10A of the passenger compartment of the pillar garnish 10. With this configuration, the H-shaped slit 31 allows parts of the sound-absorbing material 30 to open on both sides (front and rear directions) from the vertical slit 33 toward the outside of the passenger compartment, like so-called double doors.

[0034] Furthermore, the length of the horizontal slit 32 is set so that, when the sound-absorbing material 30 is placed in a predetermined position on the outer surface 10A of the passenger compartment of the pillar garnish 10, its front end is positioned at the same position as the front end of the reinforcing rib 27 of the rear clip seat 20B or slightly forward of the front end of the reinforcing rib 27, and its rear end is positioned at the same position as the rear end of the rear clip seat 20B (rear end of the side wall portion 21) or slightly rearward of the rear end of the rear clip seat 20B.

[0035] 2, a rectangular recessed cutout portion (an example of a relief portion) 38 is formed in the sound-absorbing material 30 at a portion corresponding to the portion where the front clip seat 20A is disposed. In detail, the cutout portion 38 is cut out at a position that is in contact with the upper and lower ends of the front clip seat 20A or slightly spaced from the upper and lower ends when the sound-absorbing material 30 is disposed at a predetermined position on the outer surface of the pillar garnish 10, and the depth of the cutout from the front end of the pillar garnish 10 is set so that the cutout portion 38 reaches the rear end of the front clip seat 20A.

[0036] When attaching the sound-absorbing material 30 to the exterior surface 10A of the pillar garnish 10, the sound-absorbing material 30 is brought close so that the H-shaped slit 31 is positioned in the rear clip seat 20B and the notch 38 is positioned in the front clip seat 20A, and the back surface of the sound-absorbing material 30 is pressed against the exterior surface 10A of the pillar garnish 10. Then, as shown in FIGS. 1 to 5, the H-shaped slit 31 is pushed open like a double door by the rear clip seat 20B toward the exterior of the vehicle cabin. The front clip seat 20A is also positioned within the notch 38.

[0037] More specifically, of the two portions of the sound-absorbing material 30 that rise up and are surrounded by a U-shape by the pair of horizontal slits 32 and vertical slits 33, the rearwardly positioned rear rising portion 34 is positioned along the pair of open ends 21A of the rear clip seat 20B, and is supported in its raised state by the pair of open ends 21A. The pair of open ends 21A are spaced apart from each other, and the space between them is an opening in the side wall portion 21. Therefore, the plate surface of the rear rising portion 34 is supported in a flat state by spanning the pair of open ends 21A. In other words, the pair of open ends 21A of the side wall portion 21 can support the rear rising portion 34 in a flat state, and can be said to constitute a flat support portion. In this way, by overlapping the plate-shaped rear rising portion 34 with the flat support portion (the pair of open ends 21A), the rear rising portion 34 is stably supported over a wide area, thereby improving the positioning accuracy of the sound-absorbing material 30 with respect to the pillar garnish 10. The front rising portion 35 disposed at the front is disposed along the end surface 27A of the reinforcing rib 27.

[0038] In this state, the sound absorbing material 30 can clamp the rear clip seat 20B from both the front and rear sides while utilizing its elastic force, so that displacement of the sound absorbing material 30 in the front-rear direction relative to the pillar garnish 10 is effectively suppressed.

[0039] Furthermore, since the sound-absorbing material 30 can be positioned relative to the pillar garnish 10 at two locations, the front clip seat 20A and the rear clip seat 20B, rotation of the sound-absorbing material 30 relative to the pillar garnish 10 is restricted. As shown in Fig. 1, two clip seats 20 are provided side by side in the longitudinal direction of the long pillar garnish 10, which makes it easier to ensure free space in the short direction and prevents these clip seats 20 from getting in the way when wiring harnesses and the like are arranged in the longitudinal direction.

[0040] Once the sound-absorbing material 30 has been positioned relative to the pillar garnish 10 in this manner, ultrasonic welding is performed to fix the position of the sound-absorbing material 30 corresponding to the welded portion 18. In this manner, the sound-absorbing material 30 is attached to the pillar garnish 10.

[0041] Next, the effects will be described. This embodiment is an attachment structure for a sound-absorbing material 30 on a pillar garnish 10, in which the pillar garnish 10 includes a rear clip seat 20B that protrudes from an outer surface 10A of the vehicle interior, the sound-absorbing material 30 is overlapped on the pillar garnish 10 and has an H-shaped slit 31 that allows a portion of the sound-absorbing material 30 to be cut and raised, the portion surrounded by the H-shaped slit 31 forms a rear rising portion 34 that rises while being supported by the rear clip seat 20B, and the rear clip seat 20B has a portion that is flat and forms flat support portions (a pair of open ends 21A) that support the rear rising portion 34, and the sound-absorbing material 30 is positioned with respect to the pillar garnish 10 by the rear rising portion 34 being supported by the flat support portions (a pair of open ends 21A).

[0042] According to the above configuration, the pair of open ends 21A of the rear clip seat 20B can be used to position the sound-absorbing material 30 relative to the pillar garnish 10. Specifically, the worker simply presses the portion surrounded by the horizontal slits 32 and the vertical slits 33 (the rear rising portion 34) with the rear clip seat 20B to raise it, and then supports the raised rear rising portion 34 with the pair of open ends 21A, thereby positioning and attaching the sound-absorbing material 30 relative to the pillar garnish 10.

[0043] Furthermore, when providing through holes at positions corresponding to the protruding portions of the sound-absorbing material as in the past, the through holes had to be made larger to account for installation tolerances. This meant that the sound-absorbing material tended to move relative to the vehicle interior material before being fixed, raising concerns about misalignment. Therefore, positioning marks had to be provided and the installation work had to be performed carefully in accordance with the marks. In contrast, the above-described configuration utilizes the elastic force of the rear rising portion 34 of the sound-absorbing material 30 pressing against the pair of opening ends 21A to prevent misalignment, thereby simplifying the installation work of the sound-absorbing material 30 to the pillar garnish 10. Furthermore, because the rear rising portion 34 spans the pair of opening ends 21A, it is stably supported over a wide area, improving the accuracy of positioning the sound-absorbing material 30 relative to the pillar garnish 10.

[0044] Furthermore, unlike conventional configurations in which through holes are provided at positions corresponding to the protruding portions of the sound-absorbing material, no waste material is generated, thereby reducing the cost of disposing of waste material.

[0045] In addition, the slit 31 is H-shaped, having a pair of horizontal slits 32 extending parallel to each other and a vertical slit 33 connecting the pair of horizontal slits 32 at the center in the extension direction of the pair of horizontal slits 32, and one of the parts of the sound-absorbing material 30 surrounded by the pair of horizontal slits 32 and the vertical slit 33 (rear rising portion 34) is supported by the pair of opening ends 21A, and the other is supported on the opposite side of the pair of opening ends 21A (end face 27A of the reinforcing rib 27).

[0046] When the slits are configured as an H-shape as a whole, as in the above configuration, the U-shaped portion of the sound-absorbing material 30 surrounded by the slits 32, 33 (the front rising portion 35 and the rear rising portion 34) can be configured to open on both sides (so-called double doors), and the pair of raised portions can be supported on both sides of the pair of opening ends 21A of the rear clip seat 20B and the side opposite the pair of opening ends 21A. Furthermore, with such a configuration, the rear clip seat 20B can be clamped from both sides using the elastic force of the sound-absorbing material 30, thereby further suppressing displacement of the sound-absorbing material 30 with respect to the pillar garnish 10.

[0047] In addition, a reinforcing rib 27 is provided on the opposite side of the pair of opening ends 21A of the rear clip seat 20B, rising from the outer surface 10A of the vehicle interior and protruding radially from the rear clip seat 20B, and one of the U-shaped portions of the sound-absorbing material 30 surrounded by the horizontal slits 32 and the vertical slits 33 is supported by the end face 27A of the reinforcing rib 27.

[0048] According to the above configuration, even when the rear clip seat 20B is provided with a reinforcing rib 27, the sound-absorbing material 30 can be easily attached to the pillar garnish 10 without having to position it by providing a notch or the like in the sound-absorbing material 30 to allow the reinforcing rib 27 to escape.

[0049] The pillar garnish 10 has an elongated shape, and the horizontal slit 32 is arranged along the longitudinal direction of the pillar garnish 10.

[0050] When the pillar garnish 10 is long, there is a concern that manufacturing tolerances and positioning tolerances may become large. With the above-described configuration, the horizontal slits 32 can absorb the longitudinal tolerances, making it easier to position the sound-absorbing material 30 relative to the pillar garnish 10.

[0051] The pillar garnish 10 has a front clip seat 20A protruding from the outer surface 10A of the vehicle interior, and the sound-absorbing material 30 has a recessed cutout 38 cut out from the end of the sound-absorbing material 30 at a position corresponding to the front clip seat 20A to prevent interference between the front clip seat 20A and the sound-absorbing material 30.

[0052] According to the above configuration, the sound absorbing material 30 can be positioned relative to the pillar garnish 10 at two locations, the rear clip seat 20B and the front clip seat 20A, so that rotation of the sound absorbing material 30 relative to the pillar garnish 10 can be restricted.

[0053] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included in the technical scope. Furthermore, various modifications other than those described below can be made without departing from the spirit of the invention.

[0054] (1) In the above embodiment, an automobile is used as an example of a vehicle, but the mounting structure for the sound-absorbing material disclosed in this specification can also be applied to interior materials in other ground vehicles such as trains and recreational vehicles, air vehicles such as airplanes and helicopters, and marine and underwater vehicles such as ships and submarines. Furthermore, even within an automobile, the mounting structure can be applied not only to the pillar garnish 10 but also to, for example, vehicle door trim.

[0055] (2) In the above embodiment, the clip seat 20 is used as an example of the protrusion, but it can also be used as another protrusion, such as a mounting boss.

[0056] (3) In the above embodiment, the clip seat 20 is shown as a hollow protruding portion having an opening, and the flat support portion is configured by a pair of open ends 21A. However, the protruding portion may be solid, and the flat support portion may be configured by a flat surface. In short, the flat support portion may be configured to support the rising portion stably over a wide range, such as by supporting the rising portion not at a point or a line, but by bridging the rising portion across a surface or a pair of lines.

[0057] (4) In the above embodiment, an H-shaped slit 31 is provided in the sound-absorbing material 30, but the slit may be U-shaped, for example, with one end of a pair of first slits connected by a second slit. The point is that the rising portion formed by the slit may be supported by the flat support portion of the protrusion.

[0058] (5) Furthermore, the sound-absorbing material disclosed in this specification can also be applied to protrusions that do not have reinforcing ribs.

[0059] (6) In the above embodiment, an H-shaped slit 31 is provided in the part of the sound-absorbing material 30 corresponding to the rear clip seat 20B, and a cutout 38 is provided in the part corresponding to the front clip seat 20A. However, an H-shaped slit may also be provided in the part corresponding to the front clip seat. [Explanation of symbols]
