Description

[Technical field]

[0001] The technology disclosed in this specification relates to vehicle interior materials. [Background technology]

[0002] For example, a door trim, which is an interior material for a vehicle, is composed of a combination of multiple board members. The following Patent Document 1 describes a technology that, when a part of a plurality of board members (base interior) that composes the door trim (vehicle interior material) becomes dirty or damaged, makes it possible to replace only that board member without removing the entire door trim from the vehicle body.

[0003] Specifically, the vehicle interior component of Patent Document 1 is designed so that a portion of it can be removed and attached from the inside of the vehicle cabin, and multiple plate-shaped locking pieces protrude from the inner periphery of an opening that is exposed when a removable component (board component) of the vehicle interior component is removed. The removable component can be attached by blocking the opening by inserting the insertion portion of the removable component into the insertion hole provided in these locking pieces and sliding it along the slit connected to the insertion hole.

[0004] [Patent Document 1] JP 2020-83266 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, there has been a demand for easier customization of colors and materials according to user preferences in order to improve the design and functionality of vehicle interior materials. However, the vehicle interior materials having the above-mentioned conventional configurations have room for improvement in terms of convenience and cost in terms of allowing users to customize the design and functionality themselves.

[0006] In addition, the above-mentioned vehicle interior components are based on the assumption that the attachable member (board member) will be replaced, and when the attachable member is removed, the opening and locking structure are exposed to the inside of the vehicle, so the components cannot be used as is.

[0007] The technology disclosed in this specification was completed based on the above circumstances, and aims to provide a vehicle interior material that allows users to change the design and functionality more easily and cheaply than before, and that can also be used with the replacement parts removed if not needed. [Means for solving the problem]

[0008] The technology disclosed in this specification, which was completed to solve the above-mentioned problems, is a vehicle interior material comprising a trim board that constitutes the interior surface of a vehicle, and a covering member that is removably attached to the trim board so as to cover a portion of the interior surface of the trim board, the trim board including a first board portion and a second board portion arranged adjacent to each other, a plurality of engagement holes are provided on the boundary line between the first board portion and the second board portion, the covering member covers the first board portion, and an engagement portion is provided at an end of the covering member that can be removably engaged with the engagement hole.

[0009] According to the above configuration, since the covering member can be easily attached and detached to the trim board, the user can easily change the design and functionality of the vehicle interior material by replacing the covering member. Also, since the locking structure (locking hole) for fixing the covering member to the trim board is provided on the boundary line between the first board part and the second board part, the locking structure is not noticeable, and the vehicle interior material can be used with the covering member removed, that is, with the texture and feel of the trim board itself being utilized.

[0010] The boundary line may be a step portion formed by the indoor surfaces of the first board portion and the second board portion being stepped in the indoor-outdoor direction, and the engagement hole may be drilled in the step portion in a direction along the board surface of the trim board.

[0011] According to the above-mentioned configuration, it is possible to realize a locking structure when attaching the covering member to the trim board. Also, when the covering member is removed from the trim board, the locking hole is formed at a position where it is less visible to the passengers, improving the design of the vehicle interior material (trim board) when the covering member is not used.

[0012] Among the ends of the covering member, a first covering end that is positioned at the boundary line may have a boundary line side fold portion folded back to the outside of the room, the locking portion may be fixed to the boundary line side fold portion, and the boundary line side fold portion may be overlapped on the second board portion.

[0013] According to the above configuration, the thickness of the first end portion on the covered side, which has increased due to the boundary line side fold portion, can be absorbed by utilizing the step portion, so that the first end portion on the covered side can be made to conform to the indoor surface of the first board portion without being partially raised above the indoor surface of the covering member.

[0014] The boundary line may be a groove-shaped groove recessed from the interior surface of the trim board to the exterior side, and the locking hole may be provided at a bottom of the groove.

[0015] According to the above-mentioned configuration, it is possible to realize a locking structure when attaching the covering member to the trim board. Also, when the covering member is removed from the trim board, the locking holes are difficult for passengers to see, improving the design of the vehicle interior material (trim board) when the covering member is not used.

[0016] The boundary line may be a linear arrangement of multiple recesses that are recessed from the interior surface of the trim board to the exterior side, and the locking hole may be provided at the bottom of some of the multiple recesses.

[0017] According to the above-mentioned configuration, it is possible to realize a locking structure when attaching the covering member to the trim board. Also, when the covering member is removed from the trim board, the locking holes are difficult for passengers to see, improving the design of the vehicle interior material (trim board) when the covering member is not used.

[0018] The first board portion forms part of the peripheral edge of the trim board, and a hook portion may be provided on a second covering end portion of the end of the covering member that is positioned on the peripheral edge of the trim board and that can be hooked onto the peripheral edge of the trim board.

[0019] According to the above configuration, when the first board portion constitutes a part of the peripheral edge of the trim board, it is possible to realize one locking structure for fixing the covering member to the peripheral edge of the trim board.

[0020] Among the ends of the first board portion, the board side end portion which constitutes part of the peripheral edge of the trim board is bent into a crank shape and has an end side recessed portion which is recessed from the interior surface of the first board portion, and the covered side second end portion has an end side folded portion which is folded back to the outside of the room, and the hook portion is fixed to the end side folded portion and the end side folded portion is accommodated in the end side recessed portion.

[0021] According to the above configuration, the second end portion of the covering side, whose thickness has been increased by the end side folded portion, can be accommodated in the end side recessed portion, so that the second end portion of the covering side can be aligned with the indoor surface of the first board portion without being partially raised above the indoor surface of the covering member.

[0022] The first board portion and the second board portion may be integrally formed by press molding a plate-like member. Effect of the Invention

[0023] The technology disclosed in this specification makes it possible to provide a vehicle interior material that allows users to change the design and functionality more easily and at lower cost than before, and that can also be used with the replacement parts removed if not needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] <Embodiment 1> A door trim 1, which is an interior material for a vehicle according to the first embodiment, will be described with reference to Figs. 1 to 6. The symbols FR, RR, UP, DW, IN, and OUT shown in each drawing respectively indicate the front and rear in the longitudinal direction of a vehicle as an example of a vehicle, the upper and lower in the vertical direction, and the interior side and exterior side in the interior / exterior direction of the vehicle. However, the above directions are merely defined for convenience and should not be interpreted in a restrictive manner.

[0026] 1 and 2 are perspective views of a door trim 1 as viewed from the interior side of a vehicle. The door trim 1 is mainly composed of a trim board 10 that is generally plate-shaped, and is fastened to the interior side of a door inner panel (not shown) by fastening members such as clips (not shown), thereby improving the design and livability of the vehicle interior. The trim board 10 is made of, for example, a synthetic resin (thermoplastic resin) such as polypropylene, or other materials such as a composite material made by mixing plant fiber (for example, kenaf) with a synthetic resin. In the following description, the interior side of the trim board 10 may be referred to as the "front side," and the exterior side may be referred to as the "rear side."

[0027] The trim board 10 is formed by assembling a plurality of board members together. Although not shown in detail, the trim board 10 of this embodiment is mainly formed by an upper board 11, a lower board, an armrest board, a pocket board, and the like. Among these, the upper board 11 is a portion disposed above the armrest 2, and forms a portion including an upper edge portion and a rear edge portion of the trim board 10. The front surface (surface) of the trim board 10 may be covered with a skin material made of natural leather, synthetic leather, cloth, or the like.

[0028] The upper board 11 is somewhat long in the front-rear direction when viewed from the inside of the vehicle, and has a generally trapezoidal shape with the front end inclined upward and forward. The upper end of the upper board 11 is curved and rounded, forming a protruding portion 12 that protrudes outward to the outside of the vehicle compartment (see FIG. 4).

[0029] The upper board 11 of this embodiment has a two-step shape. In detail, as shown in Fig. 2, the upper board 11 includes a first region (an example of a first board part) 13 having a substantially trapezoidal shape that is substantially similar to the outer shape of the upper board 11, including an edge part (an example of a peripheral part of a trim board) on the side of the overhanging part 12, and a second region (an example of a second board part) 18 having a substantially U-shape that is a part other than the first region 13 and surrounds the first region 13 from the front-rear direction and from below. A step part (an example of a boundary line) 14 is provided at the boundary between the first region 13 and the second region 18, and the indoor surface of the first region 13 is disposed on the indoor side of the indoor surface of the second region 18 due to the step part 14. In other words, the first region 13 and the second region 18 are disposed in a step-like shape having a step in the indoor-outdoor direction due to the step part 14 (see Figs. 4 and 6).

[0030] The first region 13 and the second region 18 are integrally formed by press-molding a plate-like member, but in this embodiment, the interior surface of the first region 13 and the interior surface of the second region 18 are subjected to different types of embossing, forming different design surfaces (see Figs. 2 and 3). Note that the interior surface of the first region 13 and the interior surface of the second region 18 may be formed to have the same design surface.

[0031] As shown in Fig. 3, the step portion 14 has a plurality of locking holes 16 arranged side by side in the extension direction of the step portion 14. These locking holes 16 are provided at positions including the end portion on the exterior side (second region 18 side) in the height direction of the step portion 14, and open in a direction along the plate surface of the upper board 11. These locking holes 16 are provided at approximately equal intervals over the entire extension direction of the step portion 14. Note that in this embodiment, these locking holes 16 are also formed at the same time during press molding.

[0032] Furthermore, of the protruding portion 12 of the upper board 11, a portion 12A (an example of the board side end portion) included in the first region 13 is bent in a crank shape toward the outside of the room (downward in Figures 4 and 5) as shown in Figures 4 and 5, forming an end side recess 17 that is recessed in a stepped shape from the indoor surface of the first region 13.

[0033] The door trim 1 of this embodiment is capable of removably mounting a covering member 20 that covers the first region 13. The covering member 20 may be, for example, a somewhat thick sheet-like member made of a resin material such as polyurethane, having cushioning properties. The entire end of the covering member 20 is folded back to the back side by a crease 21.

[0034] Hereinafter, the portion of the covering member 20 that is folded back by the fold 21 and overlapped on the inside of the fold 21 of the covering member 20 (hereinafter referred to as the central side portion 22) will be referred to as the folded back portion. A hook portion 24 is attached to an end side folded back portion (an example of a covering side second end portion) 23, which is the portion of the folded back portion that is overlapped on the protrusion portion 12 and placed in the opening for the glass window W (see Figure 4).

[0035] 5, the hook portion 24 is substantially J-shaped, and one end on the long side is attached to the covering member 20 by penetrating from the outside to the inside of the fold 21 and being sewn while being sandwiched between the end side folded portion 23 and the central side portion 22. When the hook portion 24 is attached to the covering member 20, the other short end side of the hook portion 24 extends to the back surface of the covering member 20 while following the back surface.

[0036] On the other hand, as shown in Fig. 4, a locking portion 26 is attached to a boundary line side fold portion (an example of a covering side first end portion) 25, which is a portion of the folded portion of the covering member 20 that is disposed on the boundary line (step portion 14) side between the first region 13 and the second region 18. As shown in Fig. 6, the locking portion 26 is bent into a crank shape, and one end side of the locking portion 26 is attached to the covering member 20 by sewing it while being sandwiched between the boundary line side fold portion 25 and the central side portion 22 inside the fold 21. When the locking portion 26 is attached to the covering member 20, the other end side of the locking portion 26 extends toward the inside in the radial direction of the covering member 20, along the back surface of the covering member 20.

[0037] When attaching the covering member 20 to the trim board 10 (first region 13 of the upper board 11) of the present embodiment described above, first, the hook portion 24 provided on the covering member 20 is hooked onto the edge portion (the tip portion of the end-side recessed portion 17) of the portion 12A of the overhanging portion 12 that is included in the first region 13. Then, as shown in Fig. 5, the end-side folded portion 23 that bulges outward is housed within the end-side recessed portion 17, and the upper portion of the covering member 20 is aligned with the indoor surface of the first region 13 (the indoor surface of the overhanging portion 12) without its indoor surface being raised by the end-side folded portion 23.

[0038] Next, the locking portion 26 provided on the covering member 20 is brought close to the boundary line between the first region 13 and the second region 18, i.e., the step portion 14, and the covering member 20 is stretched outward from the first region 13 while the locking portion 26 arranged on the back side of the covering member 20 is inserted into the locking hole 16 provided in the step portion 14 (see FIG. 6). The locking portion 26 is inserted into the locking hole 16 in a direction along the first region 13. When the locking portion 26 is inserted into the locking hole 16, the covering member 20 in the stretched state returns to its original state, and the end portion (covering-side first end portion) of the covering member 20 arranged on the step portion 14 side is arranged along the extension direction of the step portion 14.

[0039] 6, boundary-side folded portion 25 bulging outwardly to the outside of the room is overlapped with second region 18, and the thickness of boundary-side folded portion 25 is absorbed by step portion 14. As a result, the portion of the end of covering member 20 that is disposed along step portion 14 (boundary line) is aligned with the indoor surface of first region 13 without its indoor surface being raised by boundary-side folded portion 25.

[0040] In this way, the covering member 20 is attached so as to cover the first region 13 of the upper board 11 and is aligned with the interior surface of the first region 13. When removing the covering member 20, the engaging portions 26 and the hook portions 24 can be released from their engaged state, in the opposite manner to that during attachment.

[0041] As described above, according to this embodiment, the covering member 20 can be easily attached and detached so as to cover the first region 13 of the trim board 10 (upper board 11), so that the color and material of a part of the door trim 1 can be easily changed to suit the user's preference. In addition, if the user wishes to utilize the texture and feel of the upper board 11 itself as a design, the covering member 20 can be simply removed. In the trim board 10 of this embodiment, the locking hole 16 for locking the covering member 20 is formed along the boundary line (step portion 14) between the first region 13 and the second region 18, and is configured to be inconspicuous to the occupants, so that the door trim 1 (trim board 10) can be used without impairing the design even when the covering member 20 is removed.

[0042] Next, the effects of the present embodiment will be described. The door trim 1 of this embodiment includes a trim board 10 that constitutes the interior surface of the vehicle, and a covering member 20 that is detachably attached to the trim board 10 so as to cover a part of the interior surface of the trim board 10. The trim board 10 includes a first region 13 and a second region 18 that are arranged adjacent to each other, and a plurality of locking holes 16 are provided on the boundary line between the first region 13 and the second region 18. The covering member 20 covers the first region 13, and an engaging portion 26 that can be detachably engaged with the locking hole 16 is provided at an end of the covering member 20.

[0043] According to the above configuration, the covering member 20 can be easily attached and detached to the trim board 10, so the user can easily change the design and functionality of the door trim 1 by replacing the covering member 20. In addition, since the locking structure (locking hole 16) for fixing the covering member 20 to the trim board 10 is provided on the boundary line between the first area 13 and the second area 18, the locking structure is not noticeable, and the door trim 1 can be used with the covering member 20 removed, that is, with the texture and feel of the trim board 10 itself being utilized.

[0044] In addition, the boundary line is a step portion 14 formed by the indoor surfaces of the first area 13 and the second area 18 being stepped in the indoor / outdoor direction, and the locking holes 16 are drilled in the step portion 14 in a direction along the board surface of the trim board 10.

[0045] According to the above configuration, it is possible to implement one locking structure when attaching the covering member 20 to the trim board 10. In addition, when the covering member 20 is removed from the trim board 10, the locking holes 16 are formed at positions that are less visible to occupants, improving the design of the trim board 10 (door trim 1) when the covering member 20 is not used.

[0046] In addition, the portion of the end of the covering member 20 that is positioned at the step portion 14 has a boundary line side fold portion 25 that is folded back to the outside of the room, and a locking portion 26 is fixed to the boundary line side fold portion 25, and the boundary line side fold portion 25 is adapted to be overlapped with the second region 18.

[0047] According to the above configuration, the thickness of the end of the covering member 20, which has been increased by the boundary line side fold portion 25, can be absorbed by utilizing the step portion 14, so that the end arranged on the boundary line can be made to follow the indoor surface of the first region 13 without being partially raised above the indoor surface of the covering member 20.

[0048] In addition, the first region 13 forms part of the peripheral edge (upper edge) of the trim board 10, and a hook portion 24 is provided on the end of the covering member 20 that is positioned on the peripheral edge of the trim board 10 (end side fold portion 23) so as to be hooked onto the peripheral edge of the trim board 10.

[0049] According to the above configuration, when the first region 13 constitutes a part of the peripheral edge of the trim board 10, a locking structure for fixing the cover member 20 to the peripheral edge of the trim board 10 can be realized.

[0050] In addition, part 12A of the end of the first region 13 which constitutes part of the peripheral edge of the trim board 10 is bent into a crank shape and has an end side recess 17 which is recessed from the interior surface of the first region 13, and the end of the covering member 20 which is positioned on the peripheral edge of the trim board 10 has an end side fold-back portion 23 which is folded back to the outside of the room, a hook portion 24 is fixed to the end side fold-back portion 23, and the end side fold-back portion 23 is adapted to be accommodated in the end side recess 17.

[0051] According to the above configuration, the end of the covering member 20, whose thickness has been increased by the end side fold portion 23, can be accommodated in the end side recess portion 17, so that the end of the covering member 20 can be aligned with the indoor surface of the first region 13 without being partially raised above the indoor surface of the covering member 20.

[0052] Moreover, the first region 13 and the second region 18 are integrally formed by press-molding a plate-like member.

[0053] <Embodiment 2> Next, a second embodiment will be described with reference to Fig. 7 to Fig. 11. This embodiment differs from the first embodiment in the configuration of the boundary between the first region 33 and the second region 38. In the following, only the configuration different from the first embodiment will be described, and the same configuration as the first embodiment will be assigned a reference number with 20 added to it, and duplicated description will be omitted.

[0054] In the upper board 31 of this embodiment, the boundary between the first region 33 and the second region 38 is formed by a combination of a groove portion (an example of a boundary) 34 and a stitch portion (an example of a boundary) 35. To explain in detail below, the upper board 31 is provided with a groove-shaped groove portion 34 recessed from the indoor surface of the upper board 31 to the outdoor side at the boundary between the first region 33 and the second region 38 (see FIG. 7). It can also be said that the upper board 31 is divided into the first region 33 and the second region 38 by the groove portion 34. Note that in this embodiment, the indoor surface of the first region 33 and the indoor surface of the second region 38 are flush with each other.

[0055] On the inside of groove portion 34, a plurality of protrusions 35A rising from the bottom of groove portion 34 are arranged at equal intervals along the extension direction of groove portion 34. In other words, the inside of groove portion 34 has an uneven shape in which protrusions 35A and recesses (an example of recesses) 35B are arranged in order (see FIG. 8).

[0056] The end face on the protruding side of the convex portion 35A is set to be approximately flush with the indoor surface of the upper board 31. With this configuration, it can also be said that the boundary between the first region 33 and the second region 38 is formed by a linear arrangement of multiple concave portions 35B (an example of a concave portion) that are recessed from the indoor surface of the upper board 31 toward the outdoor side.

[0057] Such a concave-convex shape appears as a regular stitch-like pattern to a passenger looking at the door trim 3 from inside the vehicle (see FIG. 7). In this manner, the boundary line of this embodiment is formed by a combination of the groove portion 34 and the stitch-like concave portion 35B and convex portion 35A (stitch portion 35).

[0058] The bottoms of the grooves 34 divided into a plurality of parts, i.e., some of the linearly arranged recesses 35B, are provided with locking holes 36 penetrating in a direction substantially perpendicular to the plate surface of the upper board 31 (see FIG. 8). These locking holes 36 are provided in some of the bottoms of the divided grooves 34 (the recesses 35B), so that they are not noticeable to the occupants.

[0059] On the other hand, in covering member 40 of this embodiment, locking portion 46 provided on boundary line side folded portion (one example of covering side first end portion) 45, which is a portion disposed along the boundary line between first region 33 and second region 38, has an L-shaped bent shape as shown in Figures 9 and 11. This locking portion 46 is attached to covering member 40 by sewing one end side thereof while being sandwiched between boundary line side folded portion 45 and central side portion 42 inside fold 41, and the other end side protrudes toward the back surface side of covering member 40 in a direction intersecting with the back surface. In addition, a claw portion 47 is provided at the protruding end on the other end side.

[0060] In addition, of this covering member 40, a hook portion 44 similar to that in embodiment 1 is attached to an end side folded portion (an example of a second end portion on the covering side) 43, which is the portion that is placed in the opening for the glass window W at the upper end of the door trim 3.

[0061] Furthermore, the covering member 40 of this embodiment has a configuration in which a sheet-like intervening member 48 is laminated on the exterior surface side. This intervening member 48 is intended to absorb the thickness of the end of the covering member 40 increased by the end side folded portion 43 and the boundary line side folded portion 45, and to make the end of the covering member 40 conform to the interior surface of the first region 33 without being partially raised above the interior surface of the covering member 40.

[0062] The boundary line of the door trim 3 of this embodiment is a groove-shaped groove portion 34 recessed from the interior surface of the trim board 30 (upper board 31) to the exterior side, and the locking hole 36 is provided in the bottom of the groove portion 34. The boundary line can also be said to be a line of multiple recesses 35B recessed from the interior surface of the trim board 30 to the exterior side, and the locking hole 36 is provided in the bottom of some of the multiple recesses 35B.

[0063] According to the above configuration, it is possible to implement one locking structure when attaching the covering member 40 to the trim board 30. In addition, when the covering member 40 is removed from the trim board 30, the locking holes 36 are difficult for passengers to see, improving the design of the door trim 3 (trim board 30) when the covering member 40 is not used.

[0064] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included within the technical scope.

[0065] (1) In the above embodiment, the boundary line is formed by a combination of the step portion 14 or the groove portion 34 and the stitch portion 35, but the boundary line is not limited to the above embodiment. For example, the boundary line may be formed only by a groove portion or only by a stitch portion.

[0066] (2) In the above embodiment, the first area 13, 33 and the second area 18, 38 are both part of the upper board 11, 31, but the first board part and the second board part may be separate board members. In such a case, the boundary line may be the boundary between the two board members.

[0067] (3) In the above embodiment, the covering member 20, 40 covers the first region 13, 33 including the peripheral portion of the trim board 10, 30, but the covering member 60 may cover an area that does not include the peripheral portion of the trim board 50, as shown in Fig. 12, for example. In such a case, the hook portion is not necessary, and the covering member 60 can be attached to the trim board 50 by providing an engaging portion on the entire end portion of the covering member 60.

[0068] (4) The configurations of the locking portion and the hook portion, and the mounting structure thereof to the covering member are not limited to those in the above-described embodiment.

[0069] (5) In the above embodiment 1, the locking holes 16 are formed at the same time as the upper board 11 is press-molded, but the locking holes 56 may be drilled in a direction along the plate surface of the upper board 51 after the upper board 51 is press-molded (see FIG. 13).
