However, in the method of welding the side end 4A of the skin 4 to the back surface of the resin core 2 as in the conventional automobile interior part 1 described above, the upper end face 3B of the reinforcing rib 3 is peaked As shown in FIG. 6, the side end 4A of the skin 4 swells in a chevron as shown in FIG. 6 and is in a strongly pulled state, and in a portion other than the Since different parts having different tensions occur alternately, when the interior part 1 for an automobile completed as a product is viewed from the front, particularly at the side end portion 1A of the interior part 1 for an automobile, the product surface by the waving of the surface material 4 There is a problem that the appearance defect of occurs.
本発明は、表皮材の波打ちによる製品表面の外観不良を効果的に防止するのに好適な自動車用内装部品を提供することである。
An object of the present invention is to provide an automotive interior part suitable for effectively preventing the appearance defect of the product surface due to the surface material being waved.
前記目的を達成するために、本発明は、所要形状に成形された樹脂芯材と、前記樹脂芯材の裏面に凸設された複数の補強リブと、前記樹脂芯材の表面に貼付された表皮材と、を備え、前記表皮材の側方端末部は、前記樹脂芯材の表面側から同樹脂芯材の側方端末部および前記補強リブの端末部を巻き込んで同樹脂芯材の裏面側に位置し、かつ、前記補強リブの上端面に対して溶着で固定された状態になっていることを特徴とする。
In order to achieve the above object, the present invention is applied to the surface of the resin core material, a resin core material formed into a required shape, a plurality of reinforcing ribs provided on the back surface of the resin core material, and And a side end portion of the surface covering material is wound on a side end portion of the resin core material and an end portion of the reinforcing rib from the front surface side of the resin core material to form a back surface of the resin core material.

In the present invention, the height of the fixed portion by welding may be uniform when viewed from the surface of the surface material.
また、前記本発明において、前記樹脂芯材の裏面における前記補強リブの配置間隔を統一することにより、前記溶着による固定部の間隔が均一になっていることを特徴としてもよい。
In the present invention, the intervals of the fixing portions by welding may be uniform by unifying the arrangement intervals of the reinforcing ribs on the back surface of the resin core material.
本発明では、前述の通り、自動車用内装部品における表皮材の端末部の具体的な構成として、当該表皮材の側方端末部は、樹脂芯材の表面側から同樹脂芯材の側方端末部および補強リブの端末部を巻き込んで同樹脂芯材の裏面側に位置し、かつ、補強リブの上端面に対して溶着で固定された状態になっているという構成を採用した。このため、補強リブ付近での表皮材の側方端末部の高さと、隣り合う２つの補強リブ間での表皮材の側方端末部の高さは、略同等に設定され、従来のように、補強リブの上端面を頂点として表皮材の側方端末部が山形に盛り上がって強く引っ張られた状態にならず、表皮材の側方端末部全範囲で引っ張り強さが均一化されるから、製品として完成した自動車用内装部品を正面から見たときに、表皮材の波打ちによる製品表面の外観不良が生じ難く、かかる外観不良を効果的に防止するのに好適な自動車用内装部品を提供し得る。

以下、本発明を実施するための最良の形態について、添付した図面を参照しながら詳細に説明する。
Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the attached drawings.
図１は本発明を適用した自動車用内装部品の裏面図、図２は図１のＡ矢視断面図、図３は図１の自動車用内装部品をフロントピラーに取り付けた状態の横断面図である。
1 is a back view of an interior part of a car to which the present invention is applied, FIG. 2 is a sectional view taken along arrow A of FIG. 1, and FIG. 3 is a cross-sectional view of a state where the interior part of a car shown in FIG. is there.
図１および図３を参照すると、両図の自動車用内装部品１（以下「本実施形態の自動車用内装部品１」という）は、車両のフロントガラスＦＧ左右に位置するフロントピラーＦＰに取り付けられる樹脂成形品（フロントピラーガーニッシュ）であって、所要形状に成形された樹脂芯材２と、樹脂芯材２の裏面に凸設された複数の補強リブ３と、樹脂芯材２の表面に貼付された表皮材４と、を備えている。
Referring to FIGS. 1 and 3, the automotive interior part 1 (hereinafter referred to as "the automotive interior part 1 according to the present embodiment") in both figures is a resin attached to the front pillar FP located on the left and right of the windshield FG of the vehicle. It is a molded product (front pillar garnish), and is adhered to the surface of resin core material 2 with resin core material 2 formed into a required shape, a plurality of reinforcing ribs 3 provided on the back surface of resin core material 2 and protruding. And a skin material 4.
本実施形態の自動車用内装部品１をフロントピラーＦＰに取り付けるための具体的な取付け構造は周知であるため、その詳細説明は省略するが、例えば公知のクリップを使用して図３のようにフロントピラーＦＰに取り付けることができる。
A specific attachment structure for attaching the interior part 1 for an automobile according to the present embodiment to the front pillar FP is known, and thus the detailed description thereof is omitted. For example, as shown in FIG. It can be attached to the pillar FP.
補強リブ３は、図２のように樹脂芯材２と同じ樹脂で一体成形されるとともに、図１のように樹脂芯材２の幅方向を横断するように形成されている。
The reinforcing rib 3 is integrally formed of the same resin as the resin core 2 as shown in FIG. 2, and is formed to cross the width direction of the resin core 2 as shown in FIG.
本実施形態の自動車用内装部品１は、フロントピラーＦＰに取り付けたとき、フロントピラーＦＰに沿って斜め上方に立ち上がった姿勢になる。このため、本実施形態の自動車用内装部品１は、中央付近より約上半分の範囲Ｓ１が運転者あるいは助手席搭乗者の頭部に最も近い部位となるため、かかる範囲Ｓ１に位置する補強リブ３の配置間隔は、それ以外の範囲Ｓ２、すなわち中央付近より約下半分の範囲Ｓ２に位置する補強リブ３の配置間隔に比べて、密となるように設定している。
When mounted on the front pillar FP, the interior part 1 for an automobile of the present embodiment has a posture in which it rises obliquely upward along the front pillar FP. For this reason, in the interior part 1 for an automobile according to the present embodiment, the area S1 which is about the upper half of the area near the center is the portion closest to the head of the driver or the passenger on the front passenger seat. The arrangement interval of 3 is set to be smaller than the arrangement interval of the reinforcing rib 3 located in the other range S2, that is, the range S2 which is about the lower half of the vicinity of the center.
以上のように範囲Ｓ１と範囲Ｓ２では補強リブ３の配置間隔が相違するが、それぞれの範囲Ｓ１、Ｓ２内では補強リブ３の配置間隔を等間隔に設定している。つまり、範囲Ｓ１に含まれる補強リブ３の配置間隔は等しい（補強リブ３の配置間隔の統一）。また、範囲Ｓ２に含まれる補強リブ３の配置間隔も等しい（補強リブ３の配置間隔の統一）。
As described above, the arrangement intervals of the reinforcing ribs 3 are different in the range S1 and the range S2, but in the respective ranges S1 and S2, the arrangement intervals of the reinforcing ribs 3 are set at equal intervals. That is, the arrangement intervals of the reinforcing ribs 3 included in the range S1 are equal (unification of the arrangement intervals of the reinforcing ribs 3). Moreover, the arrangement | positioning space of the reinforcing rib 3 contained in range S2 is also equal (unification of the arrangement | positioning space of the reinforcing rib 3).
図３を参照すると、表皮材４の側方端末部４Ａは、樹脂芯材２の表面側から同樹脂芯材２の端末部２Ａおよび補強リブ３の端末部３Ａを巻き込んで同樹脂芯材２の裏面側に位置し、かつ、補強リブ３の上端面３Ｂに対して溶着ＷＤで固定された状態になっている。
Referring to FIG. 3, the side end 4 </ b> A of the surface material 4 includes the end 2 </ b> A of the resin core 2 and the end 3 </ b> A of the reinforcing rib 3 from the surface side of the resin core 2. And is fixed to the upper end face 3B of the reinforcing rib 3 by welding WD.
フロントピラーＦＰには、フロントガラスＦＧの左右縁部を支持する手段として、フロントガラス受けＲＥが設けられている。このようなフロントガラス受けＲＥを車内から視認できないように隠蔽するために、本実施形態の自動車用内装部品１における左右側方端末部１Ａ、１Ｂのうち、一方の側方端末部１Ａ付近は、フロントガラス受けＲＥの先端と対向するように配置される。このような配置の構成上、補強リブ３の端末部３Ａも同様にフロントガラス受けＲＥの先端と対向するように配置される。この場合、自動車走行時におけるガタツキ音として補強リブ３の端末部３Ａとフロントガラス受けＲＥの先端との接触音が発生することを防止する必要があるため、本実施形態の自動車用内装部品１においては、補強リブ３の端末部３Ａとフロントガラス受けＲＥの先端との対向ギャップＧＰを可能な限り狭く設定しているので、かかる対向ギャップＧＰを避けた位置で前記溶着ＷＤを行っている。
The front pillar FP is provided with a windshield support RE as a means for supporting the left and right edges of the windshield FG. In order to conceal such a windshield receiver RE so that it can not be visually recognized from the inside of the vehicle, one of the left and right side terminal portions 1A, 1B in the interior part 1 for an automobile of this embodiment It is arranged to face the front end of the windshield receiver RE. In the configuration of such an arrangement, the end portion 3A of the reinforcing rib 3 is similarly arranged to face the front end of the windshield receiver RE. In this case, it is necessary to prevent the contact noise between the end 3A of the reinforcing rib 3 and the front end of the windshield receiver RE from being generated as rattling noise when the vehicle is traveling. Since the facing gap GP between the end portion 3A of the reinforcing rib 3 and the tip of the windshield receiver RE is set as narrow as possible, the welding WD is performed at a position avoiding the facing gap GP.
図２を参照すると、表皮材４の表面から見て溶着ＷＤによる固定部の高さｈは均一になっている。これにより、補強リブ３付近での表皮材４の側方端末部４Ａの高さと、隣り合う２つの補強リブ３、３間での表皮材４の側方端末部４Ａの高さは、略同等に設定されている。したがって、補強リブ３の上端面３Ｂを頂点として表皮材４の側方端末部４Ａが山形に盛り上がって強く引っ張られた状態にはならず、表皮材４の側方端末部４Ａ全範囲で引っ張り強さは均一化されている。
Referring to FIG. 2, the height h of the fixed portion by welding WD is uniform as viewed from the surface of the surface material 4. Thereby, the height of the side end 4A of the surface material 4 in the vicinity of the reinforcing rib 3 and the height of the side end 4A of the surface 4 between two adjacent reinforcing ribs 3 are substantially equal. It is set to. Therefore, the side end portion 4A of the surface material 4 is raised in a mountain shape with the upper end face 3B of the reinforcing rib 3 as the apex, and is not in a strongly pulled state. The height is uniformed.
前記溶着ＷＤは、例えば図４（ａ）に示した第１の溶着ホーンＨ１を表皮材４の側方端末部４Ａに押し当てる方式（以下「第１の溶着方式」という）を採用することも可能であるが、本実施形態の自動車用内装部品１においては、溶着強度を高めるために、図４（ｂ）に示した第２の溶着ホーンＨ２を表皮材４の側方端末部４Ａに押し当てる方式（以下「第２の溶着方式」という）を採用した。
The welding WD may adopt, for example, a method of pressing the first welding horn H1 shown in FIG. 4A against the side end 4A of the surface material 4 (hereinafter referred to as "first welding method"). Although possible, in the interior part 1 for an automobile of the present embodiment, the second welding horn H2 shown in FIG. 4B is pushed to the side end 4A of the surface material 4 in order to enhance the welding strength. Adopted a method (hereinafter referred to as "the second welding method").
第１の溶着ホーンＨ１はその先端が図４（ａ）のように長く尖った形状になっているため、第１の溶着方式では点状の溶着形態になること、これに加えて更に、補強リブ３の上端面３Ｂは幅が狭いため、そのような点状の溶着では溶着されない部分（溶着抜け）が生じやすいことから、第１の溶着方式では溶着強度が不十分となるおそれがある。
Since the first welding horn H1 has a long pointed end as shown in FIG. 4 (a), the first welding method has a point welding shape, and in addition to that, reinforcement is further performed. Since the upper end face 3B of the rib 3 is narrow in width, a portion (welding loss) not to be welded is likely to occur in such spot welding, and the welding strength may be insufficient in the first welding method.
この一方、第２の溶着ホーンＨ２はその先端が図４（ｂ）のように浅い凹凸の円弧面形状になっているため、第２の溶着方式の場合は、面状の溶着形態になるので、幅の狭い補強リブ３の上端面３Ｂでも溶着抜けが発生し難く、十分な溶着強度が得られる。
On the other hand, since the second welding horn H2 has an arc surface with shallow unevenness as shown in FIG. 4 (b), in the case of the second welding method, the welding shape is planar. Even in the upper end surface 3B of the narrow reinforcing rib 3, welding omission hardly occurs, and sufficient welding strength can be obtained.
樹脂芯材２の裏面から見た補強リブ３の高さに関する具体的な構成として、本実施形態の自動車用内装部品１では、フロントピラーＦＰの図示しない凹凸形状等に対応する等の設計上の理由から、補強リブ３の高さに高低差を設けているが、これに限定されることはない。例えば、すべての補強リブ３の高さを略同じ高さで統一する、または、所定範囲内に位置する補強リブ３の高さを略同じ高さで統一し、かつ、その所定範囲以外に位置する補強リブ３の高さを略同じ別の高さで統一するなど、補強リブ３の高さやその統一方式は必要に応じて適宜変更することができる。
As a specific configuration regarding the height of the reinforcing rib 3 viewed from the back surface of the resin core material 2, in the interior part 1 for an automobile according to the present embodiment, the design of the front pillar FP corresponding to the uneven shape etc. Although the height difference is provided in the height of the reinforcing rib 3 for the reason, it is not limited to this. For example, the heights of all the reinforcing ribs 3 are unified at substantially the same height, or the heights of the reinforcing ribs 3 located within a predetermined range are unified at substantially the same height, and positions other than the predetermined range The height of the reinforcing rib 3 and the unifying method thereof can be appropriately changed as needed, for example, the height of the reinforcing rib 3 may be unified at substantially the same other height.
以上説明した本実施形態の自動車用内装部品１によると、その表皮材４の側方端末部４Ａの具体的な構成として、前述の通り、当該表皮材４の側方端末部４Ａは、樹脂芯材２の表面側から同樹脂芯材２の側方端末部２Ａおよび補強リブ３の端末部３Ａを巻き込んで同樹脂芯材２の裏面側に位置し、かつ、補強リブ３の上端面３Ｂに対して溶着で固定された状態になっているという構成を採用した。このため、補強リブ３付近での表皮材４の側方端末部４Ａの高さと、隣り合う２つの補強リブ３、３間での表皮材４の側方端末部４Ａの高さは、略同等に設定され、従来のように、補強リブ３の上端面３Ｂを頂点として表皮材４の側方端末部４Ａが山形に盛り上がって強く引っ張られた状態にはならず、表皮材４の側方端末部４Ａ全範囲で引っ張り強さが均一化されるから、製品として完成した自動車用内装部品１を正面から見たときに、表皮材４の波打ちによる製品表面の外観不良が生じ難いという利点がある。
According to the automobile interior part 1 of the present embodiment described above, as a specific configuration of the side terminal 4A of the surface material 4, as described above, the side terminal 4A of the surface material 4 is a resin core The side end 2A of the resin core 2 and the end 3A of the reinforcing rib 3 are wound from the surface side of the material 2 and positioned on the back side of the resin core 2 and on the upper end face 3B of the reinforcing rib 3 On the other hand, it adopted the composition that it was in the state where it was fixed by welding. For this reason, the height of the side end 4A of the surface material 4 in the vicinity of the reinforcing rib 3 and the height of the side end 4A of the surface 4 between two adjacent reinforcing ribs 3 are substantially equal. As in the prior art, the side end 4A of the skin 4 is raised in a mountain shape with the upper end face 3B of the reinforcing rib 3 as the apex, and it is not in a strongly pulled state. Since the tensile strength is uniformed in the entire range of the part 4A, there is an advantage that when the interior part 1 for an automobile completed as a product is viewed from the front, appearance defects of the product surface due to waving of the skin material 4 are unlikely to occur .
前述のように補強リブ３の配置間隔を統一する構成は、溶着ＷＤによる固定部の間隔を均一に設定できるので、表皮材４の側方端末部４Ａの引っ張り強さをより一層均一なものとするのに好適である。
As described above, in the configuration in which the arrangement intervals of the reinforcing ribs 3 are unified, since the intervals of the fixing parts by welding WD can be set uniformly, the tensile strength of the side end 4A of the surface material 4 is made more uniform. It is suitable for
前述のように補強リブ３の高さを統一する構成は、溶着ＷＤによる固定部の高さｈを均一なものとする上で採用でき、かかる構成の採用によって、表皮材４の側方端末部４Ａの引っ張り強さをより一層均一に設定することが可能である。
As described above, the configuration for unifying the heights of the reinforcing ribs 3 can be adopted to make the height h of the fixed portion by welding WD uniform, and by adopting such a configuration, the side end portion of the surface material 4 It is possible to set the tensile strength of 4A more uniformly.
本発明は、以上説明した第１および第２実施形態に限定されるものではなく、本発明の技術的思想内で当分野において通常の知識を有する者により多くの変形が可能である。
The present invention is not limited to the first and second embodiments described above, and many modifications can be made by those skilled in the art within the technical concept of the present invention.
