Description

本発明は内装部品のクッション材固定構造に係り、特に、高い位置決め精度が要求されず簡単に取り付けることができる作業性に優れたクッション材固定構造に関するものである。   The present invention relates to a cushioning material fixing structure for interior parts, and more particularly to a cushioning material fixing structure excellent in workability that can be easily attached without requiring high positioning accuracy.

例えば車両用ドアトリム等の内装部品の裏面側に、吸音性、緩衝性等の所定の機能を有するクッション材を設けることが行われている。特許文献１はその一例で、クッション材に孔部やスリットが設けられ、内装部品側の係止用突起をその孔部やスリットに挿通させて係止用突起そのもの、または係止用突起に設けられた係止爪などにクッション材を係止するようになっている。   For example, a cushioning material having predetermined functions such as sound absorption and shock absorbing properties is provided on the back side of interior parts such as vehicle door trims. Patent Document 1 is an example, and a cushion member is provided with a hole or a slit, and the locking projection on the interior part side is inserted through the hole or slit to provide the locking projection itself or the locking projection. The cushion material is locked to the locking claw or the like.

特開２００３−８１０２１号公報JP 2003-81021 A

しかしながら、このようにクッション材に孔部等を設けて内装部品側の係止用突起を挿通させて係止する場合、両者の相対的な位置決めを行って取付作業を行う必要があるため、必ずしも作業性が良くない。また、孔部等の位置のばらつきで、内装部品に対するクッション材の取付位置がずれたり、その位置ずれに起因してガタが発生したりする可能性がある。   However, when a hole or the like is provided in the cushion material in this way and the locking protrusion on the interior part side is inserted and locked, it is necessary to perform the mounting operation by performing relative positioning of both, Workability is not good. In addition, there is a possibility that the mounting position of the cushion material with respect to the interior part is shifted due to variations in the position of the hole or the like, or the play is generated due to the positional shift.

本発明は以上の事情を背景として為されたもので、その目的とするところは、高い位置決め精度が要求されることなくクッション材を所望の取付位置に簡単に且つ適切に固定することができるようにすることにある。   The present invention has been made against the background of the above circumstances, and the object of the present invention is to allow the cushioning material to be easily and appropriately fixed at a desired mounting position without requiring high positioning accuracy. Is to make it.

かかる目的を達成するために、第１発明は、合成樹脂製の内装部品にシート状のクッション材を固定するためのクッション材固定構造であって、(a) 前記内装部品には、前記クッション材が押し込まれる押込み穴が設けられるとともに、その押込み穴の内方に向かって突き出す複数の係止爪が設けられており、(b) 前記クッション材が、前記複数の係止爪を弾性変形させつつ前記押込み穴の中心部分に押し込まれることにより、その押込み穴内に押し込まれた押込み部がその複数の係止爪に係止されて抜け止めされることを特徴とする。   In order to achieve this object, the first invention is a cushion material fixing structure for fixing a sheet-like cushion material to an interior part made of synthetic resin, and (a) the cushion material includes the cushion material. And a plurality of locking claws protruding inward of the pressing hole, and (b) the cushion material elastically deforms the plurality of locking claws. By being pushed into the center portion of the pushing hole, the pushing portion pushed into the pushing hole is locked by the plurality of locking claws to be prevented from coming off.

第２発明は、第１発明の内装部品のクッション材固定構造において、前記複数の係止爪は、前記押込み穴の中心に対して対称的に設けられた２つの係止爪を対として、その押込み穴の中心まわりに等角度間隔で２対以上設けられていることを特徴とする。   According to a second aspect of the present invention, in the cushion material fixing structure for interior parts of the first aspect, the plurality of locking claws are paired with two locking claws provided symmetrically with respect to the center of the push hole. Two or more pairs are provided at equiangular intervals around the center of the push hole.

このようなクッション材固定構造においては、内装部品のクッション材を固定すべき部位に押込み穴および複数の係止爪が設けられており、その複数の係止爪を弾性変形させつつクッション材が押込み穴の中心部分に押し込まれることにより、その押込み部が複数の係止爪に係止されて抜け止めされる。したがって、例えばクッション材を内装部品の所定位置に平置きし、上記押込み穴の中心の上方に位置する部分を押込み工具等によりその押込み穴内に押し込むだけで固定することが可能であり、高い位置決め精度が要求されることなくクッション材を所望の配設位置に簡単に且つ適切に固定することができる。   In such a cushion material fixing structure, a push hole and a plurality of locking claws are provided at a portion where the cushion material of the interior part is to be fixed, and the cushion material is pushed in while elastically deforming the plurality of locking claws. By being pushed into the center portion of the hole, the pushing portion is locked by the plurality of locking claws and is prevented from coming off. Therefore, for example, it is possible to fix the cushion material by simply placing the cushion material flat at a predetermined position on the interior part and pushing the portion located above the center of the push hole into the push hole with a push tool or the like. Therefore, the cushion material can be easily and appropriately fixed at a desired arrangement position without requiring the above.

第２発明は、押込み穴の中心に対して対称的に設けられた２つの係止爪を対として、その押込み穴の中心まわりに等角度間隔で２対以上の係止爪が設けられている場合で、押込み穴の中心部分に押し込まれた押込み部が、その２対以上すなわち４つ以上の係止爪により両側から対称的に挟持されるように係止されるため、押込み部の抜止め荷重すなわちクッション材の引き剥がし強度が押込み穴の中心まわりにおいて略均等に得られ、クッション材が内装部品から離脱しないように一層適切に固定される。   In the second invention, two pairs of locking claws provided symmetrically with respect to the center of the pressing hole are paired, and two or more pairs of locking claws are provided at equal angular intervals around the center of the pressing hole. In some cases, the pushing portion pushed into the center portion of the pushing hole is locked so that it is symmetrically sandwiched from both sides by two or more pairs, that is, four or more locking claws. The load, i.e., the peeling strength of the cushion material, is obtained substantially evenly around the center of the push hole, and the cushion material is more appropriately fixed so as not to be detached from the interior part.

本発明は、ドアトリムやラゲージサイドトリム、ピラートリム、各部の内装パネル等の車両用内装部品の裏面に吸音性、緩衝性等の所定の機能を有するクッション材を固定する場合に好適に適用されるが、車両用以外の内装部品にクッション材を固定する場合にも適用され得る。クッション材は、フェルトや軟質ポリウレタンフォーム等の折り曲げ変形可能な柔軟性を有するシート状乃至軟質板状のものである。   The present invention is preferably applied to a case where a cushion material having a predetermined function such as sound absorption and shock absorbing properties is fixed to the back surface of a vehicle interior part such as a door trim, a luggage side trim, a pillar trim, and an interior panel of each part. The present invention can also be applied to the case where a cushion material is fixed to an interior part other than for a vehicle. The cushion material is in the form of a sheet or a soft plate having flexibility that can be bent and deformed, such as felt and flexible polyurethane foam.

クッション材は、例えば内装部品の複数箇所の固定部位にそれぞれ本発明のクッション材固定構造が適用されて、その複数箇所で内装部品に固定されるが、１箇所の固定部位だけで本発明のクッション材固定構造によりクッション材が内装部品に固定されるものでも良い。   For example, the cushion material fixing structure of the present invention is applied to a plurality of fixing parts of an interior part, and the cushion material is fixed to the interior part at the plurality of parts. The cushion material may be fixed to the interior part by the material fixing structure.

複数の係止爪は、押込み穴の中心まわりに所定の間隔（隙間）を隔てて設けられても良いが、単に切込みやスリット等が放射状に設けられて複数の係止爪に分離するだけで、クッション材が押し込まれる前の自然状態において互いに略接するように設けられても良い。要するに、押込み穴の中心部分すなわち複数の係止爪の中心部分にクッション材が押し込まれる際に、その係止爪が弾性的に曲げ変形させられてそのクッション材の押込みが許容され、弾性復元力でその押込み部に係止爪が係止され、所定の抜止め荷重で抜け止めすることができれば良い。上記押込み穴は例えば略円形とされるが、係止爪の数に応じて多角形状としたり楕円形状としたりしても良い。   The plurality of locking claws may be provided at a predetermined interval (gap) around the center of the push hole, but the cuts, slits, etc. are provided in a radial manner and separated into the plurality of locking claws. Further, they may be provided so as to be substantially in contact with each other in a natural state before the cushion material is pushed. In short, when the cushion material is pushed into the central portion of the push hole, that is, the central portion of the plurality of locking claws, the locking claws are elastically bent and deformed to allow the cushion material to be pushed in, and the elastic restoring force Therefore, it is only necessary that the locking claw is locked to the pushing portion and can be prevented from coming off with a predetermined retaining load. The pushing hole is, for example, substantially circular, but may be polygonal or elliptical depending on the number of locking claws.

複数の係止爪は、第２発明のように押込み穴の中心に対して対称的に設けられ、押込み部を両側から対称的に挟持して抜け止めするように構成されるが、第１発明の実施に際しては、例えば押込み穴の中心まわりに等角度間隔で奇数個設けるようにしても良し、複数の係止爪を不等間隔で設けることもできるなど、種々の態様が可能である。   The plurality of locking claws are provided symmetrically with respect to the center of the pressing hole as in the second invention, and are configured to hold the pressing portion symmetrically from both sides to prevent it from coming off. In carrying out the above, for example, an odd number may be provided at equal angular intervals around the center of the push hole, and various modes such as a plurality of locking claws may be provided at unequal intervals are possible.

係止爪は、単に押込み穴の中心へ向かって内装部品と略平行に突き出すだけでも良いが、例えば先端側をクッション材の押込み方向へ斜めに傾斜させるようにすれば、クッション材を押込み穴の中心部分に押し込む際の作業が容易になるとともに、クッション材に抜出し方向の力が作用した場合に押込み部が係止爪に引っ掛かり易くなり、その押込み部の抜出しが一層効果的に防止されて強固に固定される。上記傾斜は、係止爪を全体的に傾斜させても良いが、クッション材に接する側の面を傾斜面として先端側程薄くするだけでも良い。   The locking claw may simply protrude toward the center of the push hole substantially parallel to the interior part.For example, if the tip side is inclined obliquely in the push direction of the cushion material, the cushion material is inserted into the push hole. The work when pushing into the center part becomes easy, and when the force in the pulling direction acts on the cushion material, the pushing part is easily caught by the latching claw, and the pushing out of the pushing part is further effectively prevented and strengthened. Fixed to. The above-mentioned inclination may be made to incline the locking claw as a whole, but it is also possible to make the surface on the side in contact with the cushion material an inclined surface and make it thinner toward the tip side.

上記係止爪はまた、押込み穴の中心線方向から見た平面視の先端形状が矩形や台形、凸円弧、或いは凹円弧など種々の形状を採用できるが、平面視において先端が尖った三角形状とし、その先端がクッション材の押込み部に食い込んで抜出し不能に係止されるようにすることもできる。複数の三角形が鋸歯状に連なるように設けることもできる。   The locking claw can also adopt various shapes such as a rectangular shape, a trapezoidal shape, a convex arc, or a concave arc shape when viewed from the center line direction of the push hole. In addition, the front end can bite into the pushing portion of the cushion material and be locked so as not to be extracted. A plurality of triangles may be provided so as to be continuous in a sawtooth shape.

複数の係止爪は、例えば射出成形等により内装部品と一体成形されるが、別体に構成されてインサート成形や接着、溶着等により内装部品に一体的に固定されるものでも良い。内装部品のクッション材固定部位には、例えば押込み穴および複数の係止爪が内装部品の本体から所定寸法だけ浮き上がった位置に設けられるように中空の突出部が設けられ、押込み穴内に押し込まれたクッション材の前記押込み部がその突出部の内側に収容されるようにすることが望ましい。但し、係止爪や押込み穴を内装部品の板状の本体部分に直接設けることも可能で、その場合はクッション材が配設される側と反対側に押込み部が露出するため、必要に応じて例えばその押込み部を覆蓋するカバー等を設ければ良い。   The plurality of locking claws are integrally formed with the interior part by, for example, injection molding or the like, but may be configured separately and fixed integrally to the interior part by insert molding, adhesion, welding, or the like. In the interior material cushion material fixing part, for example, a hollow protrusion is provided so that the push hole and the plurality of locking claws are raised by a predetermined dimension from the body of the interior component, and is pushed into the push hole. It is desirable that the pushing portion of the cushion material is accommodated inside the protruding portion. However, it is also possible to directly provide locking claws and push holes in the plate-like main body part of the interior part, in which case the push part is exposed on the side opposite to the side where the cushioning material is disposed, For example, a cover that covers the pushing portion may be provided.

上記中空の突出部は、例えば押込み穴に対応して円筒形状とされ、その円筒形状の先端部分に押込み穴や係止爪が設けられるが、先端部分に押込み穴および係止爪を設けることができる形状であれば、横断面がＵ字形状や四角形等の多角形の枠形状などでも良い。横断面がＵ字形状やコの字形状など、側壁の一部を開口させた形状の場合、スライド型等を用いて中空突出部を内装部品と一体成形することが可能である。突出部を別体に構成して接着や溶着などで内装部品に一体的に固設する場合は、円筒形状や多角形の枠形状等の閉じ断面の側壁を有する中空突出部を採用することもできる。   The hollow projecting portion has, for example, a cylindrical shape corresponding to the pressing hole, and a pressing hole and a locking claw are provided at the tip portion of the cylindrical shape, but the pressing hole and the locking claw may be provided at the tip portion. As long as it is a shape that can be used, the cross section may be a U-shape or a polygonal frame shape such as a quadrangle. When the cross section is a U-shaped or U-shaped shape with a part of the side wall opened, the hollow protrusion can be integrally formed with the interior part using a slide mold or the like. When the projecting part is configured separately and is integrally fixed to the interior part by bonding or welding, a hollow projecting part having a closed cross-sectional side wall such as a cylindrical shape or a polygonal frame shape may be employed. it can.

クッション材の材質によっては、押込み穴の中心部分に押し込まれる際に、クッション材の他の部分を押込み穴の中心部分に向かって引き込む方向のテンション（張力）が発生し、クッション材が位置ずれする可能性がある。このため、前記押込み部となる被押込み部位の周囲に切込み乃至スリット（開口）を予め設けておき、押込み穴内に押し込まれる際にその切込みやスリットが拡開させられることによりテンションを緩和し、クッション材の位置ずれが抑制されるようにすることが望ましい。切込みやスリットは、被押込み部位の周囲の複数箇所に設けることが望ましい。なお、この切込みやスリットは、被押込み部位の周囲に適当に設けられれば良く、必ずしも高い位置精度が要求されるものではない。   Depending on the material of the cushion material, when it is pushed into the center part of the push-in hole, tension (tension) in the direction of drawing the other part of the cushion material toward the center part of the push-in hole is generated, and the cushion material is displaced. there is a possibility. For this reason, a cut or slit (opening) is provided in advance around the portion to be pushed that becomes the pushing portion, and when being pushed into the pushing hole, the notch or the slit is widened to relieve the tension and cushion. It is desirable to suppress the displacement of the material. It is desirable to provide cuts and slits at a plurality of locations around the pressed portion. It should be noted that the cuts and slits may be appropriately provided around the pressed part, and high positional accuracy is not necessarily required.

以下、本発明の実施例を、図面を参照しつつ詳細に説明する。
図１は、本発明が適用された車両用ドアトリム１０を示す概略図で、(a) は意匠面側すなわち車両の室内側を示す正面図、(b) は反対の裏面側を示す背面図、(c) は(b) におけるIC−IC断面の拡大図である。この車両用ドアトリム１０は内装部品に相当するもので、合成樹脂材料にて一体成形されており、ドアの内部（車室の外側）に位置する裏面１２にはクッション材１４が固定されている。クッション材１４は、吸音性或いは緩衝性を有するフェルト等の柔軟性を有するシート状の部材で、本実施例では周囲の６箇所の固定部位１６ａ〜１６ｆにおいて、それぞれ車両用ドアトリム１０に一体に設けられた係止部２０に係止されて一体的に固定されるようになっている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view showing a vehicle door trim 10 to which the present invention is applied, wherein (a) is a front view showing a design surface side, that is, a vehicle interior side, and (b) is a rear view showing an opposite back side. (c) is an enlarged view of the IC-IC cross section in (b). The vehicle door trim 10 corresponds to an interior part, is integrally formed of a synthetic resin material, and a cushion material 14 is fixed to a back surface 12 located inside the door (outside the passenger compartment). The cushion material 14 is a sheet-like member having flexibility such as felt or shock absorbing cushion. In this embodiment, the cushion material 14 is provided integrally with the vehicle door trim 10 at each of the six fixed portions 16a to 16f. It is locked to the locking portion 20 and is fixed integrally.

図２は、車両用ドアトリム１０にクッション材１４を固定するクッション材固定構造を説明する概略図で、(a) は車両用ドアトリム１０のうち上記係止部２０が設けられた部分を切り出して部分的に示す斜視図、(b) はクッション材１４のうち係止部２０に固定される部分（例えば図１(b) の固定部位１６ａ）を切り出して部分的に示す斜視図、(c) は係止部２０にクッション材１４が固定された状態を示す斜視図である。係止部２０は、車両用ドアトリム１０のうち比較的平坦な平板状部分１０ｆに設けられており、その平板状部分１０ｆに設けられた中空突出部２２を主体として構成されている。中空突出部２２は、横断面がＵ字形状の中空の突出部で、平板状部分１０ｆに略垂直に立設されており、スライド型を用いて車両用ドアトリム１０と一体に成形されている。   FIG. 2 is a schematic diagram for explaining a cushion material fixing structure for fixing the cushion material 14 to the vehicle door trim 10. FIG. 2A is a partial view of the vehicle door trim 10 provided with the locking portion 20. (B) is a perspective view partially showing a portion of the cushion material 14 fixed to the locking portion 20 (for example, the fixing portion 16a in FIG. 1 (b)), and (c) is a partial perspective view. FIG. 6 is a perspective view showing a state in which a cushion material 14 is fixed to the locking portion 20. The locking portion 20 is provided in a relatively flat flat plate-like portion 10f of the vehicle door trim 10, and is mainly configured by a hollow protruding portion 22 provided in the flat plate-like portion 10f. The hollow projecting portion 22 is a hollow projecting portion having a U-shaped cross section, is erected substantially perpendicular to the flat plate portion 10f, and is integrally formed with the vehicle door trim 10 using a slide mold.

中空突出部２２の先端部、すなわち車両用ドアトリム１０の本体である平板状部分１０ｆから所定寸法だけ浮き上がった位置には、クッション材１４が押し込まれる押込み穴２４が設けられるとともに、その押込み穴２４の中心Ｓに向かって突き出す複数の係止爪２６が所定の間隔を隔てて設けられている。この係止爪２６は、押込み穴２４の中心Ｓまわりに等角度間隔で８つ設けられていて、押込み穴２４の中心Ｓに対して対称的に位置するものが、それぞれ相対向するように設けられる一対の挟持爪を構成しており、押込み穴２４の中心Ｓ部分に絞られるように押し込まれたクッション材１４の略球形の押込み部１４ｒ（図１(c) 参照）をそれぞれ両側から対称的に挟持して抜止めする。本実施例では４対の係止爪２６により、押込み穴２４の中心Ｓまわりにおいて略均等に押込み部１４ｒが挟持されて抜止めされる。また、この押込み部１４ｒは、中空突出部２２の内部に収容される。   A push hole 24 into which the cushion material 14 is pushed is provided at the tip of the hollow protrusion 22, that is, a position that is lifted by a predetermined dimension from the flat plate portion 10 f that is the main body of the vehicle door trim 10. A plurality of locking claws 26 protruding toward the center S are provided at predetermined intervals. Eight locking claws 26 are provided at equal angular intervals around the center S of the push hole 24, and those that are symmetrically located with respect to the center S of the push hole 24 are provided so as to face each other. A pair of sandwiching claws are formed, and the substantially spherical pushing portions 14r (see FIG. 1 (c)) of the cushion material 14 pushed so as to be narrowed down to the center S portion of the pushing hole 24 are symmetrical from both sides. Hold it to prevent it from being removed. In the present embodiment, the pushing portions 14r are clamped and evenly held around the center S of the pushing hole 24 by the four pairs of locking claws 26. Further, the pushing portion 14 r is accommodated inside the hollow projecting portion 22.

上記係止爪２６は、車両用ドアトリム１０の平板状部分１０ｆと略平行に設けられているが、その上面すなわちクッション材１４と接する側の面は、先端側程クッション材１４の押込み方向へ斜め乃至は円弧状に傾斜させられていて、先端側程板厚が薄くされている。これにより、係止爪２６の弾性変形が可能となり、この弾性変形でクッション材１４の押込みが許容されるとともに、傾斜面によりクッション材１４を円滑に押し込むことができる。また、クッション材１４に抜出し方向の力が作用した場合には、前記押込み部１４ｒが係止爪２６に引っ掛かり易くなり、その押込み部１４ｒの抜出しが一層効果的に防止されて強固に固定される。   The locking claw 26 is provided substantially in parallel with the flat plate-like portion 10 f of the vehicle door trim 10, but its upper surface, that is, the surface in contact with the cushion material 14 is inclined toward the pushing direction of the cushion material 14 toward the distal end side. Or it is made to incline in circular arc shape, and plate | board thickness is made thin as the front end side. Thereby, the latching claw 26 can be elastically deformed, the pushing of the cushion material 14 is allowed by the elastic deformation, and the cushion material 14 can be pushed smoothly by the inclined surface. Further, when a force in the pulling direction is applied to the cushion material 14, the pushing portion 14r is easily caught by the locking claw 26, and the pushing portion 14r is more effectively prevented from being pulled out and firmly fixed. .

上記係止爪２６はまた、押込み穴２４の中心線方向から見た平面視において先端が尖った三角形状を成しており、その先端がクッション材１４の押込み部１４ｒに食い込むことにより、その押込み部１４ｒの抜出しが更に効果的に防止される。   The latching claw 26 also has a triangular shape with a sharp tip in a plan view seen from the center line direction of the push-in hole 24, and the push-in pushes into the push-in portion 14r of the cushion material 14 so that the push-in The extraction of the portion 14r is further effectively prevented.

一方、クッション材１４が押込み穴２４の中心Ｓ部分に絞られるように押し込まれる際に、クッション材１４の他の部分を押込み穴２４の中心Ｓに向かって引き込む方向のテンション（張力）が発生し、クッション材１４が位置ずれする可能性がある。このため、前記押込み部１４ｒとなる被押込み部位１４ｓ（図２(b) 参照）の周囲には、予め複数の円弧状の切込み２８が設けられ、押込み穴２４内に押し込まれる際に、その切込み２８が拡開させられることによりテンションを緩和し、クッション材１４の位置ずれを抑制するようになっている。この切込み２８は、被押込み部位１４ｓの周囲に等角度間隔で複数（実施例では４つ）設けられており、押込み部１４ｒの周囲の全周に亘って略均等にテンションが緩和される。図１の(c) および図２の(c) は、何れも切込み２８が拡開させられた状態である。なお、上記切込み２８は、被押込み部位１４ｓの周囲に適当に設けられれば良く、必ずしも高い位置精度が要求されるものではない。   On the other hand, when the cushion material 14 is pushed so as to be squeezed to the center S portion of the push hole 24, tension (tension) is generated in a direction in which the other portion of the cushion material 14 is drawn toward the center S of the push hole 24. The cushion material 14 may be displaced. For this reason, a plurality of arc-shaped cuts 28 are provided in advance around the pushed portion 14s (see FIG. 2B) serving as the push-in portion 14r, and the cuts are made when pushed into the push-in hole 24. By expanding 28, the tension is relaxed and the displacement of the cushion material 14 is suppressed. A plurality (four in the embodiment) of the cuts 28 are provided at equal angular intervals around the pressed portion 14s, and the tension is alleviated substantially evenly around the entire periphery of the pressed portion 14r. 1 (c) and FIG. 2 (c) are both in a state where the cut 28 is expanded. The cut 28 may be appropriately provided around the pressed portion 14s, and high position accuracy is not necessarily required.

図３は、上記係止部２０によってクッション材１４が挟持されるように、そのクッション材１４を固定する際の手順を説明する図で、先ず(a) に示すように裏面１２が上方を向くように裏向きとされた車両用ドアトリム１０の所定位置にクッション材１４を平置きする。そして、円柱形状の押込み具３０を用いて、押込み穴２４の中心Ｓ部分の真上に位置する被押込み部位１４ｓを(b) に示すように押込み穴２４内に押し込むと、クッション材１４は、係止爪２６を下方へ弾性変形させつつ主として切込み２８よりも内側の中間部分が押込み穴２４の中心Ｓ部分に絞られるように押し込まれ、押込み部１４ｒが中空突出部２２の内部に突き出す。被押込み部位１４ｓが押込み穴２４内に押し込まれる際に切込み２８が開くことにより、クッション材１４の他の部分を押込み穴２４に向かって引き込む方向のテンション（張力）が緩和され、クッション材１４の位置ずれが抑制される。また、複数の係止爪２６の弾性復元力で、その押込み部１４ｒが適切に挟持され、(c) に示すように押込み具３０を上方へ抜き出しても、クッション材１４の押込み部１４ｒは複数の係止爪２６により所定の抜止め荷重で挟持されて抜け止めされ、略球形状を成すように中空突出部２２の内部に保持される。   FIG. 3 is a diagram for explaining a procedure for fixing the cushion material 14 so that the cushion material 14 is sandwiched by the locking portion 20. First, as shown in FIG. 3A, the back surface 12 faces upward. Thus, the cushion material 14 is laid flat at a predetermined position of the vehicle door trim 10 that is turned face down. Then, using the cylindrical pushing tool 30, when the pushed portion 14s located immediately above the center S portion of the pushing hole 24 is pushed into the pushing hole 24 as shown in FIG. While the latching claw 26 is elastically deformed downward, the middle portion inside the notch 28 is pushed so as to be constricted to the center S portion of the pushing hole 24, and the pushing portion 14 r protrudes into the hollow protruding portion 22. When the notched portion 14 s is pushed into the push hole 24, the notch 28 is opened, so that the tension (tension) in the direction in which the other portion of the cushion material 14 is drawn toward the push hole 24 is relieved, and the cushion material 14 Misalignment is suppressed. Further, even if the pushing portion 14r is appropriately clamped by the elastic restoring force of the plurality of locking claws 26 and the pushing tool 30 is pulled upward as shown in FIG. 5C, the pushing portion 14r of the cushion material 14 has a plurality of pushing portions 14r. The retaining claws 26 are sandwiched by a predetermined retaining load and are prevented from coming off, and are held inside the hollow projecting portion 22 so as to form a substantially spherical shape.

上記押込み具３０は、作業者が目視による手作業で操作してクッション材１４を押込み穴２４の中心Ｓ部分に押し込むようにしても良いが、車両用ドアトリム１０が予め定められた所定位置に位置決めして載置される組付テーブルの上方に、エアシリンダや送りねじ機構等の駆動装置により上下動させられる可動ブロックの所定位置、すなわち押込み穴２４の中心Ｓの真上の部分に押込み具３０を予め固定し、その可動ブロックを下降させてクッション材１４の被押込み部位１４ｓを押込み穴２４内に押し込むようにしても良い。前記固定部位１６ａ〜１６ｆに対応する６箇所にそれぞれ押込み具３０を装着しておくことにより、６箇所の固定部位１６ａ〜１６ｆで同時にクッション材１４を押込み穴２４内に押し込んで各係止部２０に固定することができる。   The pushing tool 30 may be manually operated by an operator to push the cushion material 14 into the center S portion of the pushing hole 24, but the vehicle door trim 10 is positioned at a predetermined position. The pusher 30 is placed at a predetermined position of the movable block that is moved up and down by a driving device such as an air cylinder or a feed screw mechanism, that is, a portion directly above the center S of the push hole 24 above the assembly table placed in this manner. May be fixed in advance, and the movable block may be lowered to push the pushed portion 14 s of the cushion material 14 into the push hole 24. By attaching the pushing tool 30 to each of the six locations corresponding to the fixing portions 16a to 16f, the cushion member 14 is simultaneously pushed into the pushing holes 24 at the six fixing portions 16a to 16f, and the respective locking portions 20 are inserted. Can be fixed to.

このように、本実施例の車両用ドアトリム１０の裏面１２には、複数の固定部位１６ａ〜１６ｆに対応して複数の係止部２０が一体に設けられ、その複数の固定部位１６ａ〜１６ｆにおいてクッション材１４が一体的に固定されるようになっている。その場合に、係止部２０は、押込み穴２４および複数の係止爪２６を備えており、その複数の係止爪２６を弾性変形させつつクッション材１４が押込み穴２４の中心Ｓ部分に押し込まれることにより、その押込み部１４ｒが複数の係止爪２６に係止されて抜け止めされる。したがって、図３に示すようにクッション材１４を車両用ドアトリム１０の所定位置に平置きし、押込み穴２４の上方に位置する被押込み部位１４ｓを押込み具３０により押込み穴２４の中心Ｓ部分に押し込むだけで固定することが可能であり、高い位置決め精度が要求されることなくクッション材１４を所望の配設位置に簡単に且つ適切に固定することができる。   Thus, the back surface 12 of the vehicle door trim 10 of the present embodiment is provided with a plurality of locking portions 20 corresponding to the plurality of fixing portions 16a to 16f, and the fixing portions 16a to 16f are integrated with each other. The cushion material 14 is fixed integrally. In that case, the locking portion 20 includes a push hole 24 and a plurality of lock claws 26, and the cushion material 14 is pushed into the center S portion of the push hole 24 while elastically deforming the lock claws 26. As a result, the pushing portion 14r is locked by the plurality of locking claws 26 and is prevented from coming off. Therefore, as shown in FIG. 3, the cushion member 14 is laid flat at a predetermined position of the vehicle door trim 10, and the pushed portion 14 s located above the pushing hole 24 is pushed into the center S portion of the pushing hole 24 by the pushing tool 30. The cushion member 14 can be easily and appropriately fixed at a desired arrangement position without requiring high positioning accuracy.

また、本実施例では、押込み穴２４の中心Ｓに対して対称的に設けられた２つの係止爪２６を対として、その押込み穴２４の中心Ｓまわりに等角度間隔で４対の係止爪２６が設けられているため、押込み穴２４の中心Ｓ部分に押し込まれた押込み部１４ｒが、その４対すなわち計８つの係止爪２６により両側から対称的に挟持されるように係止される。これにより、押込み部１４ｒの抜止め荷重すなわちクッション材１４の引き剥がし強度が、押込み穴２４の中心Ｓまわりにおいて略均等に得られるようになり、クッション材１４が車両用ドアトリム１０から離脱しないように一層適切に固定される。   Further, in this embodiment, two locking claws 26 provided symmetrically with respect to the center S of the push hole 24 are used as a pair, and four pairs of locks are formed at equal angular intervals around the center S of the push hole 24. Since the claw 26 is provided, the pushing portions 14r pushed into the center S portion of the pushing hole 24 are locked so that the four pairs, that is, a total of eight locking claws 26 are symmetrically sandwiched from both sides. The Accordingly, the retaining load of the pushing portion 14r, that is, the peeling strength of the cushion material 14 can be obtained substantially evenly around the center S of the pushing hole 24 so that the cushion material 14 is not detached from the vehicle door trim 10. More properly fixed.

また、本実施例では、複数の係止爪２６の上面すなわちクッション材１４に接する側の面が、先端側へ向かうに従ってクッション材１４の押込み方向へ傾斜させられ、その先端側程板厚が薄くされているため、係止爪２２が弾性変形し易くなるとともにクッション材１４を押込み穴２４に対して円滑に押し込むことができるようになり、その押込み作業が容易になる一方、クッション材１４の球状の押込み部１４ｒに抜出し方向の力が作用した場合に係止爪２６に引っ掛かり易くなり、その押込み部１４ｒの抜出しが一層効果的に防止されて強固に固定される。   Further, in this embodiment, the upper surfaces of the plurality of locking claws 26, that is, the surfaces in contact with the cushion material 14 are inclined in the pushing direction of the cushion material 14 toward the distal end side, and the plate thickness is reduced toward the distal end side. Therefore, the latching claw 22 is easily elastically deformed, and the cushion material 14 can be smoothly pushed into the push-in hole 24, and the push-in operation is facilitated, while the spherical push-in of the cushion material 14 is performed. When a force in the extraction direction acts on the portion 14r, it becomes easy to be caught by the locking claw 26, and the extraction of the pushing portion 14r is further effectively prevented and firmly fixed.

また、本実施例では、係止爪２６が、押込み穴２４の中心線方向から見た平面視において先端が尖った三角形状を成しているため、その先端がクッション材１４の押込み部１４ｒに食い込むことにより、その押込み部１４ｒの抜出しが更に効果的に防止される。   Further, in this embodiment, the locking claw 26 has a triangular shape with a pointed tip in a plan view as viewed from the center line direction of the pushing hole 24, so that the tip is formed on the pushing portion 14 r of the cushion material 14. By biting in, the extraction of the pushing portion 14r is further effectively prevented.

また、本実施例では、クッション材１４の被押込み部位１４ｓの周囲に複数の切込み２８が予め設けられており、その被押込み部位１４ｓが押込み穴２４内に押し込まれる際にその切込み２８が拡開することにより、クッション材１４の他の部分を押込み穴２４に向かって引き込む方向のテンション（張力）が緩和され、クッション材１４の位置ずれが抑制される。   Further, in this embodiment, a plurality of cuts 28 are provided in advance around the pressed portion 14 s of the cushion material 14, and when the pressed portion 14 s is pushed into the push hole 24, the cuts 28 are expanded. By doing so, the tension (tension) in the direction in which the other part of the cushion material 14 is pulled toward the push hole 24 is relaxed, and the displacement of the cushion material 14 is suppressed.
