Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, when the second member is a member that decorates the vehicle interior material, there is a need to change it to a different design. However, when using a tether clip as in Patent Document 1 above, it is relatively difficult for an ordinary person to remove or assemble the tether clip. Further, if the assembling method is incorrect, there is a risk that the function of preventing the second member from scattering may not be exhibited during a vehicle collision or the like.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide an attachment structure for vehicle interior materials that has a function of preventing the second member from scattering with respect to the first member and enables the second member to be easily attached to and detached from the first member.

Means for Solving the Problems

[0006] In order to solve the above problems, the mounting structure of the vehicle interior material disclosed in the present application has the following configuration. (1) A mounting structure for a vehicle interior material for mounting the vehicle interior material to a panel forming an outer shell of a passenger compartment, wherein the vehicle interior material includes a first member serving as a main body covering the panel, and a second member attached to the first member so as to cover a part of the first member. The second member includes a plate-shaped main body portion covering a part of the first member, a plurality of engaging portions formed on the back surface side of the main body portion and engaging with an engaged portion of the first member, and a bolt portion provided so as to extend outward from the back surface of the main body portion to the outside of the vehicle compartment beyond the engaging portion, having an outer dimension of the tip end larger than the outer dimension of the shaft portion on the base end side and having a male screw portion formed with a thread. The second member is provided with a first member through hole having an inner dimension larger than the outer dimension of the male screw portion formed in the first member, a panel through hole formed in the panel, the panel through hole being larger than the outer dimension of the shaft portion of the bolt portion and allowing the male screw portion to engage therewith. The second member is attached to the first member by engaging the plurality of engaging portions with the engaged portion in a state where the male screw portion of the bolt portion passes through the first member through hole and the panel through hole to the outside of the vehicle compartment. This is the mounting structure of the vehicle interior material.

[0007] In the mounting structure of the vehicle interior material disclosed in the present application, a method of attaching the second member to the first member will be described. In this case, the male screw portion at the tip of the bolt portion is passed through the first member through hole and pressed against the panel through hole. Next, the second member is rotated around the axis of the bolt portion to screw the male screw portion into the panel through hole. Then, the second member is rotated as it is until the male screw portion passes through the panel through hole and inserted. After that, the orientation of the second member is adjusted to match the first member, and each of the plurality of engaging portions is engaged with the corresponding engaged portion, thereby completing the attachment of the second member to the first member.

[0008] In the mounting structure of the vehicle interior material disclosed in the present application, even if a plurality of engaging portions are disengaged from the engaged portion, the male screw portion of the bolt portion does not come out of the panel through-hole, and this male screw portion functions as an anchor that catches and stops on the panel. Therefore, in the mounting structure of the vehicle interior material disclosed in the present application, even an ordinary person other than an operator who manufactures the vehicle or the like can relatively easily attach the second member to the first member, and can surely exhibit the anchor function of the bolt portion to prevent the second member from scattering.

[0009] Further, in the mounting structure of the vehicle interior material having the above configuration, it is possible to adopt various aspects shown below.

[0010] (2) The mounting structure of the vehicle interior material according to item (1), wherein the hole edge portion of the first member through-hole abuts or is close to the hole edge portion of the panel through-hole of the panel.

[0011] In the mounting structure of the vehicle interior material having this configuration, since the first member through-hole and the panel through-hole are substantially continuous, when attaching the second member, the male screw portion of the bolt portion can be easily aligned with the panel through-hole.

[0012] (3) The first member has a bulging portion that bulges toward the outside of the vehicle compartment, The first member through-hole is formed at the tip of the bulging portion, The mounting structure of the vehicle interior material according to item (2), wherein the inner dimension on the vehicle compartment inner side of the bulging portion is made smaller toward the first member through-hole.

[0013] Since the bolt portion is provided on the back side of the main body portion of the second member, it is difficult to grasp the position of the bolt portion when attaching the second member to the first member, and it is difficult to align the male screw portion of the bolt portion with the first member through-hole. According to the mounting structure of the vehicle interior material having this configuration, the inner wall of the bulging portion guides the male screw portion toward the first member through-hole, so that the alignment of the bolt portion can be performed more easily.

[0014] (4) The engaging portion is claw-shaped and catches and stops on the engaged portion, and is the mounting structure of the vehicle interior material according to any one of items (1) to (3).

[0015] The mounting structure of the vehicle interior material with this configuration can relatively easily engage and disengage the engaging portion with respect to the engaged portion, so that the attachment and detachment of the second member with respect to the first member can be performed relatively easily.

[0016] (5) The panel is a door panel of a vehicle side door, The vehicle interior material is a door trim attached to the door panel, The second member is a decorative member that decorates the first member, which is the trim main body member, and is the mounting structure of the vehicle interior material according to any one of items (1) to (4).

[0017] The mounting structure of the vehicle interior material with this configuration is adopted for a vehicle side door and is configured to change the design of the side door. The vehicle interior mounting structure disclosed in the present application, in which the attachment and detachment of the second member with respect to the first member is easy, is suitable.

Effect of the Invention

[0018] According to the present invention, it is possible to provide a mounting structure for a vehicle interior material that has a function of preventing scattering of the second member with respect to the first member and enables easy attachment and detachment of the second member with respect to the first member.

Embodiments for Carrying Out the Invention

[0020] A side door 10 for a vehicle, which is an embodiment in which the attachment structure of the interior material for a vehicle of the present invention is adopted, will be described in detail with reference to FIGS. 1 to 7. Note that in a part of the drawings, directions are indicated using the signs Fr, Rr, IN, OUT, U, D, which represent the front side, rear side, inner side of the passenger compartment (vehicle interior) in the vehicle width direction, outer side of the vehicle body, upper side, and lower side of the vehicle, respectively.

[0021] The side door 10 of the present embodiment is a front door and includes, as shown in FIG. 1, a door panel 12 made of a steel plate and a door trim 14. The door panel 12 is composed of an outer panel 16 and an inner panel 18. The door trim (interior material for a vehicle) 14 is attached so as to cover the inner side of the vehicle compartment of the inner panel 18.

[0022] The door trim 14 includes a generally plate-shaped lower board 20 that constitutes a relatively lower portion, a generally plate-shaped upper board 22 that constitutes a relatively upper portion, and an armrest board 24 that is disposed between the lower board 20 and the upper board 22 and bulges inward of the vehicle compartment. Further, the door trim 14 includes an ornament board (decoration member) 26 for decoration and is attached so as to overlap the upper board 22 that is a trim main body member. The ornament board 26 can be detached from the vehicle interior so that, for example, it can be replaced with one having a different design. Since the side door 10 of the present embodiment has a characteristic structure, the attachment structure of the ornament board 26 will be described in detail below.

[0023] As shown in FIG. 2, the upper board 22 to which the ornament board 26 is attached is composed of a resin base material 30 and a skin material 32 adhered to the surface of the base material 30. A recess 34 is formed in the base material 30 of the upper board 22 at the location where the ornament board 26 is to be attached, and the skin material 32 is adhered to the portion excluding the recess 34. The ornament board 26 is attached so as to close the recess 34. That is, the upper board 22 corresponds to the first member, and the ornament board 26 corresponds to the second member that covers the recess 34 which is a part of the upper board 22.

[0024] As shown in FIGS. 2 and 3, the ornament board 26 includes a decoration panel 40 that is the main body for decoration and a resin base member 42 to which the decoration panel 40 is attached. The base member 42 is in a frame shape surrounding the outer edge of the decoration panel 40. These base member 42 and decoration panel 40 are the parts that function as the main body portion 26a of the ornament board 26 which is the second member that closes the recess 34.

[0025] As shown in FIG. 2, the ornament board 26 is provided with a plurality of fitting portions 46 for attaching to the upper board 22 on the back side. As shown in FIG. 3, these fitting portions 46 are the portions where resin clips 46a are attached, and the resin clips 46a are attached to the attachment portions on the back side of the base member 42 with the tips facing the outside of the vehicle cabin. The resin clips 46a have claw portions with generally mountain-shaped side surfaces, and both side surfaces are elastically deformable in a direction approaching each other with the tip as the base point. The resin clips 46a fit into the through holes 48 which are the engaged portions provided on the upper board 22, so that the claw portions on both side surfaces catch and stop at the hole edge portions of the through holes 48. Therefore, the resin clips 46a can also be pulled out from the through holes 48 by applying a certain amount of force.

[0026] In addition, as shown in FIG. 4, a tether bolt (bolt portion) 50 that linearly extends toward the outside of the vehicle compartment is fixed to the back surface side of the ornament board 26. Specifically, the tether bolt 50 is integrally formed with the base member 42 by insert molding during the injection molding of the base member 42, and is made non-rotatable relative to the base member 42. The tether bolt 50 is made of metal or a resin having higher rigidity than the resin forming the base member 42 or the upper board 22. The tether bolt 50 includes a shaft portion 52 on the proximal end side and a male screw portion 54 on the distal end side. The male screw portion 54 has threads formed thereon, and its outer diameter is larger than the outer diameter of the shaft portion. Note that the length of the male screw portion 54 is shorter than the length of the shaft portion 52. Specifically, the male screw portion 54 has a length with about two to three threads.

[0027] On the other hand, a through hole 60 (corresponding to the first member through hole and may be referred to as the "board through hole 60" in the following description) for inserting the above-described tether bolt 50 is formed in the upper board 22. The location where the board through hole 60 of the upper board 22 is formed is a bulging portion 62 that bulges in a mountain shape toward the outside of the vehicle compartment, and the board through hole 60 is formed at the end (tip) on the outside of the vehicle compartment. The bulging portion 62 has an inner dimension on the vehicle compartment side that becomes smaller toward the outside of the vehicle compartment. In other words, it is formed in a mortar shape.

[0028] In addition, a panel through hole 64 having an inner diameter smaller than the inner diameter of the board through hole 60 is formed in the inner panel 18. The panel through hole 64 is formed such that its center is aligned linearly with the center of the board through hole 60. When the upper board 22 is attached to the door panel 12, the tip of the bulging portion 62 of the upper board 22 is in contact with or close to the inner panel 18. That is, the upper board 22 is in a state where the hole edge portion of the board through hole 60 is in contact with or close to the hole edge portion of the panel through hole 64 of the inner panel 18.

[0029] Next, a method for attaching the ornament board 26 configured as described above will be described with reference to FIGS. 5 and 6 in addition to FIG. 4. Before attaching the ornament board 26, first, with the lower board 20, the upper board 22, and the armrest board 24 assembled, they are attached to the door panel 12. In that state, as described above, the board through-hole 60 of the upper board 22 and the panel through-hole 64 of the inner panel 18 are aligned. When attaching the ornament board 26, first, the tip of the tether bolt 50 is aligned with the board through-hole 60 from the vehicle interior side. At that time, since the periphery of the board through-hole 60 is formed in a mortar shape by the bulging portion 62, the tip of the tether bolt 50 abuts against the inner wall surface of the bulging portion 62 on the vehicle interior side and is guided toward the board through-hole 60.

[0030] The board through-hole 60 has an inner diameter larger than the outer dimension of the male thread portion 54 of the tether bolt 50 of the ornament board 26, and the male thread portion 54 is inserted therethrough. However, the inner diameter of the panel through-hole 64 is larger than the outer diameter of the shaft portion 52 of the tether bolt 50, but is formed in a dimension such that the threads of the male thread portion 54 mesh. That is, the tip of the tether bolt 50, that is, the tip of the male thread portion 54, after entering the board through-hole 60, will abut against the panel through-hole 64 as shown in FIG. 5. From that state, when the ornament board 26 is rotated around its axis with the tether bolt 50 as the center, the male thread portion 54 enters the panel through-hole 64. And when it is rotated by the number of threads, as shown in FIG. 6, the male thread portion 54 will pass through the panel through-hole 64.

[0031] Finally, the orientation of the ornament board 26 is adjusted to match the upper board 22, and the plurality of fitting portions 46 are fitted into the through-hole 48, which is the engaged portion of the upper board 22, thereby completing the attachment of the ornament board 26 (see FIG. 4).

[0032] Next, consider the case where a side collision occurs to the vehicle equipped with the side door 10 of the present embodiment. When a side collision occurs, due to the impact, a plurality of fitting portions 46 of the ornament board 26 may come off from the through holes 48. If all the fitting portions 46 come off, the ornament board 26 will come off from the upper board 22. Even in such a case, in the side door 10 of the present embodiment, as shown in FIG. 7, the male screw portion 54 of the tether bolt 50 catches on the vehicle-outside surface of the inner panel 18, specifically, on the hole edge portion of the panel through hole 64, and does not come out from the panel through hole 64. That is, the male screw portion 54 functions as an anchor, and it is possible to prevent the ornament board 26 from scattering.

[0033] Note that the side door 10 of the present embodiment can be changed to an ornament board 26 of a different design or material, etc. When removing the ornament board 26, the attachment procedure can be reversed. That is, remove the plurality of fitting portions 46 from the through holes 48, hold the ornament board 26, and while bringing the male screw portion 54 into contact with the vehicle-outside of the panel through hole 64, rotate the ornament board 26 around the axis of the tether bolt 50 to extract the male screw portion 54 from the panel through hole 64.

[0034] Incidentally, in a conventional side door, for example, a tether clip or the like was used to prevent a situation where the ornament board scatters toward the occupant. However, it is relatively difficult for a general person other than an operator who manufactures the vehicle, etc. to attach and remove the member using the tether clip. On the other hand, as described above, in the side door 10 of the present embodiment, the attachment and removal of the ornament board 26 can be performed relatively easily. As described above, the side door 10 of the present embodiment can relatively easily attach the ornament board 26, which is the second member, to the upper board 22, which is the first member, and can surely exhibit the anchor function of the tether bolt 50, which is the bolt portion, to prevent the ornament board 26 from scattering.

[0035] <Other embodiments> Note that the present invention is not limited to the above embodiments, and can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art.

[0036] In the above embodiment, a resin clip 46a was used to attach the second member to the first member, but it is not limited thereto. However, from the viewpoint of replacing the second member, it is desirable that the configuration be such that it can be easily attached and detached even by an ordinary person.

[0037] In the above embodiment, the tether bolt 50, which is a bolt portion, was integrated with the base member 42 by insert molding. However, as long as the bolt portion is fixed to the main body portion of the second member so as not to be relatively rotatable, the method is not limited. For example, it may be fixed by a fastener or the like, or may be integrally molded. However, it is desirable that the bolt portion be made more rigid than the main body portion or the first member of the second member so as not to break due to impact or the like.

[0038] In the above embodiment, the mounting structure of the door trim in an automobile was exemplified, but the present invention can be applied to the mounting structures of other vehicle interior materials. Furthermore, the present invention is not limited thereto, and can be widely applied to interior materials for other vehicles, railways, airplanes, ships, and other vehicles.
