Description

  The present invention relates to a vehicle interior material.

  Conventionally, a technology has been known in which a sealant is disposed along the outer peripheral edge of a door trim to seal between the door panel to which the door trim is attached and to prevent outside running noise and outside air from entering the interior of the vehicle interior. It has been. For example, in Patent Document 1, as a sealing material mounting structure, a flange portion is provided on the outer peripheral edge portion of the door trim on the door panel mounting side (vehicle compartment outer side) over the entire periphery, and the sealing material is pasted on the flange portion. A configuration is disclosed.

  And what was shown in FIG. 9 is known as a thing of a structure which affixes a sealing material on the flange part provided in the outer periphery part of the door trim. This includes a base 2 that forms the main part of the door trim 1, an outer wall 4 that rises from the outer peripheral edge of the base 2 toward the door panel 3, and is erected from the base 2 toward the door panel 3 toward the inside of the outer wall 4. The rib 5 is arranged in parallel, and the sealing material 7 is supported by the protruding end 6 of the rib 5.

JP 2009-298351 A

  However, according to such a configuration, the sealing material 7 is supported on the protruding end 6 of the rib 5 by adhering the protruding end 6 of the rib 5 and the sealing material 7 with a double-sided tape or the like. The adhesive strength to the rib 5 is weak and the mounting strength to the door trim 1 is low. Further, since the rib 5 is erected from the base 2 of the door trim 1, the protruding height of the rib 5 has to be set relatively high, and there is a concern about an increase in mold processing costs and occurrence of sink marks. The In order to avoid this, it is conceivable to suppress the protruding height of the rib 5 and increase the thickness of the sealing material. However, it is preferable because the sealing material easily falls down and the material cost increases. Absent. For this reason, the attachment structure of the sealing material which can be attached in the state which supported the sealing material stably with simple structure is requested | required.

  This invention is completed based on the above situations, Comprising: It aims at providing the interior material for vehicles which can support a sealing material stably with a simple structure.

The present invention is an interior material for a vehicle having a mounting seat portion that is attached to a vehicle body and to which a sealing material that seals between the vehicle body can be attached, and is attached to the first trim and the first trim. A second trim having an overlapping portion that overlaps the vehicle body side at an outer peripheral edge portion of the first trim, and the mounting seat portion is provided on the overlapping portion, and the mounting seat portion includes: characterized in Rukoto are formed across said second trim and the first trim.

  According to such a structure, the attachment seat part which attaches a sealing material can be provided in the superimposition part of a 2nd trim superimposed on the vehicle body side rather than a 1st trim, and an attachment seat part can be provided in the position close | similar to a vehicle body. For example, in order to increase the height from the vehicle interior material such as a door trim to the vehicle body, for example, a rib is protruded from the first trim, and the configuration in which the protruding end is a mounting seat portion is reduced or eliminated. Can do.

  And since a mounting seat part can be set to the vehicle body side by a simpler structure than before, the setting of the rib of the first trim can be reduced or eliminated, and the thickness of the sealing material is increased. And can be stably supported and attached.

  The overlapping portion is provided with a contact portion having a fastening portion for attaching to the first trim, and the attachment seat portion of the second trim is extended from the contact portion to the vehicle body side. You may be provided in the extension part. As described above, the second trim can be attached to the first trim by using the extended portion extended from the abutting portion having the fastening portion of the second trim toward the vehicle body as the mounting seat portion. It becomes possible to attach the sealing material to a position closer to the vehicle body. Thereby, since the thickness of the sealing material can be reduced, the cost can be reduced. Further, by reducing the thickness of the sealing material, stability is increased when the sealing material is sandwiched between the mounting seat portion of the vehicle interior material and the vehicle body. Therefore, the sealing material can be supported and attached more stably, which can contribute to quality improvement.

  The vehicle interior material is a door trim attached to a door panel, the first trim is a door trim main body, and the second trim is a pocket base material that forms a door pocket that opens to the inside of the vehicle together with the first trim. And the pocket side mounting seat part provided in the said pocket base material among the said mounting seat parts may protrude from the bottom part of the said door pocket. The pocket base material is small compared to the door trim body, and the degree of freedom in molding is high. For example, it is possible to set a mounting seat that presents a flat surface on the vehicle body side, supporting the seal material more stably can do. Therefore, it becomes possible to support and attach the sealing material more stably with a simpler configuration. Further, among the door pockets on the vehicle body side constituted by the pocket base material, the mounting seat portion can be further provided on the outer peripheral edge side of the vehicle interior material by projecting the pocket side mounting seat portion from the bottom. it can. In addition, by making good use of the shape of the bottom of the door pocket that curves from the vehicle body side to the vehicle interior side, the mounting seat is larger than in the conventional case where the pocket base is not provided with a mounting seat. It is not necessary to change the design of a simple molding die, and it is possible to reduce the labor required for mold processing.

<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS.
The vehicle interior material of the present embodiment exemplifies a case where the vehicle interior material is applied to a door trim 10 that constitutes a vehicle door and is attached to the interior side of the door panel 50. FIGS. 1 to 3 show the back surface of the door trim 10 (corresponding to the outside of the passenger compartment and the mounting surface to the vehicle body). In the following description, the X-axis direction in FIG. 1 will be described as the vehicle longitudinal direction, the Y-axis direction as the vehicle width direction (the vehicle interior / exterior direction), and the Z-axis direction as the vertical direction.

  The door trim 10 is roughly composed of members such as an upper base, a middle board, a lower board, and an ornament. These base materials are made of synthetic resin material such as polypropylene or woody material such as kenaf as a synthetic resin material. It is formed of a material mixed with the above. In addition, a part or all of the base material is covered with a skin material made of (synthetic) resin, (synthetic) leather, fiber or the like. Here, in this embodiment, what corresponds to a lower board among these is demonstrated as the door trim main body 11 (equivalent to a 1st trim).

  As shown in FIGS. 1 and 2, the door trim main body 11 includes a connecting portion 12 connected to an ornament, a speaker grill mounting portion 13 for mounting the speaker grill, and a door pocket portion constituting the vehicle interior side of the door pocket 14. 15 and the like are provided, and the door pocket portion 15 is formed with an opening portion 15A that opens to the vehicle interior side. As a whole, it has a flat plate shape along the plate surface of the door panel 50, and has a flange portion 17 </ b> A that is closer to the door panel 50 side than the door trim body 11 along the outer periphery of the door trim body 11. Is provided with a standing wall portion 16 that rises toward the door panel 50 (outside the passenger compartment).

  The door pocket 14 is formed between the door pocket portion 15 and a pocket base material 20 (corresponding to a second trim) that covers the door pocket portion 15 from the outside of the passenger compartment. More specifically, the pocket base material 20 is arranged opposite to the door pocket portion 15, and constitutes the side wall 21 and the bottom portion 22 in the vehicle exterior and front-rear direction among the side walls and the bottom portion in the door pocket 14. . A flange portion 23 (corresponding to an abutting portion) extending outward is provided on the outer peripheral edge of the pocket base material 20 serving as the peripheral edge of the side wall 21 and the bottom portion 22. A plurality of insertion holes 24 (corresponding to fastening portions) are formed in the flange portion 23 at predetermined intervals, and a cylindrical boss 15B protruding from the periphery of the door pocket portion 15 of the door trim main body 11 is provided. It can be inserted. After inserting the boss 15B corresponding to this insertion hole 24, the pocket base material 20 can be fixed to the door trim main body 11 by welding the tip of the boss 15B by welding means such as ultrasonic welding. (See FIGS. 3 and 4).

  The door trim main body 11 to which the pocket base material 20 is fixed is attached to the door panel 50 by a clip 41 after a sealing material 30 described later is attached to the mounting seats 17 and 26 at the outer peripheral edge thereof. The clip 41 is held by, for example, a clip seat 40 shown in FIG. More specifically, the illustrated clip seat 40 is formed by bridging across the bottom portion 22 and the flange portion 23 of the pocket base material 20, and has a seat surface 40 </ b> A that extends substantially parallel to the extending direction of the door panel 50. . A holding hole 40B is formed in the seating surface 40A, and a clip 41 made of an elastic member is held in the holding hole 40B. On the other hand, a mounting hole 51 corresponding to the clip seat 40 is formed in the door panel 50. After the clip 41 held in the clip seat 40 is elastically deformed and inserted through the mounting hole 51, the clip 41 is elastically restored so that the door trim main body 11 is attached to the door panel 50 via the pocket base material 20. Can be attached without rattling.

  Now, on the outer peripheral edge of the door trim 10, mounting seats 17 and 26 for attaching the sealing material 30 are formed across the door trim main body 11 and the pocket base material 20. First, the mounting seat portion 17 in the door trim main body 11 will be described. The mounting seat portion 17 is provided approximately on the peripheral edge along the standing wall portion 16, and the flange portion 17 </ b> A and the flange portion 17 </ b> A along the plate surface of the door panel 50. It is constructed by two parallel ribs 17 </ b> B that are erected toward the door panel 50 and extend along the standing wall portion 16. As will be described in detail later, the sealing material 30 has substantially the same thickness over its entire length, and in order to seal between the door trim 10 and the door panel 50 using this sealing material 30, each attachment is made from the door panel 50. It is preferable that the distance a to the seat parts 17 and 26 is constant. For this reason, when the distance to the door panel 50 is long due to each shape of the door trim main body 11, the distance a is adjusted by raising the rib 17B.

  Next, the pocket side mounting seat portion 26 that is a mounting seat portion in the pocket base material 20 will be described. The pocket side mounting seat portion 26 extends below the flange portion 23 (corresponding to the overlapping portion), and is provided at a position overlapping the flange portion 17A provided at the outer peripheral edge portion of the door trim main body 11. Specifically, as shown in FIGS. 3 to 6, an extended portion 25 extending further toward the door panel 50 is projected from the lower end of the lower flange portion 23 </ b> A extending downward from the bottom portion 22. The pocket-side mounting seat portion 26 is constituted by a protruding end portion 26A (see FIGS. 4 and 6) of the installation portion 25 and a seating surface 26B (see FIG. 5) that is further bent at the protruding end side and has a flat surface on the door panel 50 side. ing.

  The sealing material 30 attached to the mounting seats 17 and 26 having such a structure is made of, for example, urethane foam resin and has a strip shape with a substantially square cross section. One surface of the sealing material 30 is a bonding surface 31 and is bonded to the mounting seats 17 and 26 with a double-sided tape or the like. The thickness dimension of the sealing material 30 is substantially the same over the entire length, and is set larger than the distance a from the mounting seat portions 17 and 26 of the door trim 10 to the facing door panel 50. For this reason, when the door trim 10 is attached to the door panel 50, the thickness of the sealing material 30 is compressed to a distance a shorter than the natural length, and the sealing material 30 is in close contact with both the door trim 10 and the door panel 50. It is pinched. Thereby, since the space | interval between the outer periphery parts of the door trim 10 and the door panel 50 is sealed, the running sound from the outside and the penetration | invasion of external air into the vehicle interior side can be suppressed.

  As described above, according to the present embodiment, the mounting seat portions 17 and 26 of the sealing material 30 are formed across the door trim main body 11 and the pocket base material 20, so that the sealing material 30 can be stably provided with a simple configuration. Can be supported. That is, since the mounting seat portion for attaching the sealing material 30 can be provided in the overlapping portion of the pocket base material 20 that overlaps the door panel 50 side with respect to the door trim main body 11, the mounting seat portion can be provided at a position closer to the door panel 50. As described above, in order to increase the height from the door trim main body to the door panel, ribs are projected from the door trim main body, and the configuration in which the protruding end is the mounting seat portion can be reduced or eliminated.

  And since the mounting seat parts 17 and 26 can be set to the door panel 50 side with a simpler configuration than the prior art, the setting of the ribs 17B in the door trim main body 11 can be reduced and the thickness of the sealing material 30 is increased. Can be stably supported and attached.

  More specifically, when all the mounting seats are provided in the conventional door trim main body, for example, the mounting seat partially provided also in this embodiment so that the distance from the mounting seat to the door panel is constant. It is necessary to set the rib 17B of the portion 17 over the entire area of the outer peripheral portion serving as the mounting seat portion of the door trim body, and to use the protruding end as the mounting seat portion. However, according to such a structure, the adhesion area with respect to the sealing material which can be secured in the mounting seat portion is reduced, and there is a concern about a decrease in adhesion. In addition, setting the ribs may increase mold processing costs and cause sink marks.

  On the other hand, in this embodiment, in order to provide the pocket side mounting seat portion 26 in the overlapping portion of the pocket base material 20 that overlaps the door panel 50 side with respect to the door trim main body 11, it is provided in the door trim main body 11 as in the past. It is possible to reduce the setting of the rib having a predetermined protruding height. Therefore, by setting the rib 17B to the door trim body 11, it is possible to shorten the processing time of the molding die and reduce molding defects.

  In addition, since the pocket base material 20 is a small part with respect to the door trim main body 11, the degree of freedom in molding is high, and the seating surface 26 </ b> A having better adhesion than the ribs 17 </ b> B can be set. In this way, the setting of the rib 17B is reduced, and the flange portion 17A and the seating surface 26B that can adhere the seal member 30 more stably are set as the mounting seat portions 17 and 26, so that the sticking failure of the seal material 30 is reduced. Generation | occurrence | production can be suppressed and the sealing material 30 can be attached in the state supported more stably.

  In addition, it is also possible to lengthen the thickness dimension of the sealing material 30 and to adjust the distance from the door panel 50 to the mounting seat without setting the rib 17B. However, in this case, since the thickness of the sealing material, that is, the height of the sealing material from the mounting seat portion is increased, the sticking of the sealing material to the mounting seat portion is not stabilized, and the door trim is fixed to the door panel. At this time, there is a possibility that the sealing material falls down and a mounting failure occurs. In addition, increasing the thickness of the sealing material leads to an increase in cost, which is not preferable. For this reason, it is important to set the mounting seats 17 and 26 of the sealing material 30 closer to the door panel 50 side.

  On the other hand, in this embodiment, a part of the mounting seats 17 and 26 of the sealing material 30 is provided on the pocket base material 20 arranged on the door panel 50 side with respect to the door trim main body 11, and the pocket side mounting seat portion is further provided. 26 is constituted by the projecting end portion 26A of the extending portion 25 extending from the flange portion 23 toward the door panel 50 and the seat surface 26B provided at the tip thereof, so that the sealing material 30 can be attached at a position closer to the door panel 50. . Therefore, the cost can be reduced by avoiding the above-described problems and particularly by making the thickness of the sealing material 30 thinner. In addition, by reducing the thickness of the sealing material 30, stability is increased when the sealing material 30 is sandwiched between the mounting seats 17 and 26 on the door trim 10 side and the door panel 50. Thus, since the sealing material 30 can be attached in a more stably supported state, it is possible to contribute to quality improvement in the finished vehicle door.

  Further, by providing the mounting seat portion 26 by making good use of the shape of the bottom 22 of the door pocket 14 that curves from the door panel 50 side to the vehicle interior side, compared to the conventional case where the mounting seat portion is not provided on the pocket base material, for example. However, it is not necessary to make a major design change of the molding die, and it is possible to reduce time and effort spent on the mold processing.

  Although the first embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and for example, the following modifications may be included. In the following modifications, the same members as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and description thereof may be omitted.

A first modification of the first embodiment will be described with reference to FIG. This modified example is different from the first embodiment in that the pocket side mounting seat portion 62 protrudes from the bottom portion 61 of the pocket base material 60 separately from the flange portion 23.

  Of the pocket base material 60 constituting the door panel 50 side of the door pocket 14, a flat pocket side mounting seat 62 extending downward is projected from the bottom 61. The pocket-side mounting seat 62 is located closer to the door panel 50 than the flange 23 extending downward from the contact portion 63 with the door pocket 15 on the door trim main body 11 side of the bottom 61. Further, the pocket side mounting seat portion 62 can use the entire plate surface on the door panel 50 side as the sticking surface 62 </ b> A of the sealing material 30.

  According to such a configuration, in addition to the effects of the first embodiment, the sticking surface 62A of the pocket side mounting seat portion 62 to which the sealing material 30 is attached can be set to the door panel 50 side. As a result, the distance b from the pocket side mounting seat 62 to the door panel 50 can be set shorter, and accordingly, the thickness dimension of the sealing material 30 can be further shortened, and the cost can be reduced. Further, by providing the pocket side mounting seat portion 62 directly projecting from the bottom portion 61, a simpler configuration than extending from the flange portion 23 can be achieved. In addition, since the entire plate surface on the door panel 50 side of the pocket side mounting seat portion 62 can be used as the sticking surface 62A of the sealing material 30, the sealing material 30 can be mounted in a more stably supported state. .

[Modification 2 of Embodiment 1]

In the lower part of the clip seat 74, a pocket side mounting seat portion 72 is provided which extends further downward, that is, toward the standing wall portion 16 side. The plate surface on the door panel 50 side of the pocket side mounting seat 72 is the sticking surface 72 </ b> A of the sealing material 30.

  Even with such a configuration, the mounting seat 72 of the sealing material 30 can be provided on the pocket base material 70 side. Further, the pocket base material 70 (and the door trim body 11 fixed thereto) is extended from the clip seat 40 that is fixed to the door panel 50 and provided with the pocket side mounting seat portion 72 so that the pocket base material 70 is attached to the attaching surface 72A. The sealing material 30 can be held in a state of being pressed to the door panel 50 side by the clip 73. Therefore, it is possible to improve the sealing performance between the door trim 10 and the door panel 50 by the sealing material 30.
