Description

本発明は自動車用シートに備えるカップホルダー付のアームレスト、ヘッドレストなどの表皮一体発泡品の製造方法に関する。     The present invention relates to a method for producing an integrated foam product such as an armrest with a cup holder and a headrest provided in an automobile seat.

従来のアームレストは、例えば特開２０００−２３８５６８号公報に開示されているように、袋状に縫製した長方体状の表皮の一端面に開孔した注入孔より、パッド発泡成形用の発泡液を注入して表皮にパッドを一体発泡成形している。     As disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-238568, a conventional armrest has a foaming liquid for pad foam molding from an injection hole opened in one end face of a rectangular skin that is sewn into a bag shape. The pad is integrally foamed with the skin.

特開２０００−２３８５６８号公報JP 2000-238568 A

以上の如く、袋状の表皮内に、ウレタンフォームなどのパッド発泡成形用の発泡液を注入すると、発泡液の発泡に伴って反応ガスが発生し、この反応ガスが表皮内に空気溜まりとなり、所定形状にパッドが発泡成形されない不具合が生じる。     As described above, when a foaming liquid for pad foam molding such as urethane foam is injected into the bag-shaped skin, a reactive gas is generated along with the foaming of the foamed liquid, and this reactive gas becomes an air reservoir in the skin. There arises a problem that the pad is not foam-molded into a predetermined shape.

斯かる不具合を解消するために、表皮の内側に、発泡体のスラブ材製ワディングを接着し、このワディングに、前記反応ガスを吸着するようにしている。   In order to solve such a problem, a foam slab material wadding is adhered to the inside of the skin, and the reactive gas is adsorbed to the wadding.

そのため、従来品はあらかじめ、表皮の内側に反応ガス抜き用の前記ワディングを設ける必要がある。従って、従来品は表皮にワディングを接着する工程により加工費がかかるし、ワディングの材料費もかかる。   For this reason, it is necessary to previously provide the wadding for removing the reaction gas inside the outer skin of the conventional product. Therefore, the conventional product requires a processing cost due to the process of adhering the wadding to the skin, and also costs the material for the wadding.

そこで、本発明は表皮一体発泡品において、前記従来の不具合を除去することを目的とする。     SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the above-mentioned conventional problems in a foam integrated with a skin.

以上の目的を達成するための本請求項１の発明は、袋状に縫製した表皮内に、パッド成形用の発泡液を注入して表皮と一体にパッドを発泡成形して製造する表皮一体発泡品の製造方法であって、
前記表皮における組付け部品に被覆される部分に、前記発泡液より発生する反応ガスを外部に排出するガス排出孔を設け、当該ガス排出孔を上方に向けた状態で、前記表皮内に前記発泡液を注入するとともに、当該発泡液による前記パッドの発泡成形後、当該部分に組付け部品を後付けすることを特徴とするものである。 In order to achieve the above object, the invention according to claim 1 is an integral skin foaming produced by injecting a foaming liquid for pad molding into a bag-sewed skin and foam-molding the pad integrally with the skin. A method for manufacturing a product,
A gas exhaust hole for exhausting the reaction gas generated from the foaming liquid to the outside is provided in a portion covered with the assembly part in the skin, and the foam is formed in the skin with the gas exhaust hole facing upward. In addition to injecting the liquid, after the foaming of the pad by the foaming liquid, an assembly part is retrofitted to the part .

本請求項２の発明は、前記表皮一体発泡品はカップホルダー付アームレストであって、前記組付け部品はカップホルダーである。   In the invention according to claim 2, the foam integrated foam is an armrest with a cup holder, and the assembly component is a cup holder.

本請求項１の発明によれば、反応ガスがガス排出孔から外部に排出され、袋状 の表皮内に溜まることがない。そのため、前記従来品の如き表皮の内側に反応ガス抜き用のワディングなどの部材が不要となる。そして、ガス排出孔は組付部品によって被覆される部分に設けているので、製品の外観品質を損なうこともない。 According to the first aspect of the present invention, the reaction gas is discharged from the gas discharge hole to the outside and does not accumulate in the bag-shaped skin. Therefore, a member such as a wadding for removing the reaction gas is not required inside the skin as in the conventional product. Then, since the gas discharge hole is provided in a portion covered by the assembled components, nor detract from the appearance quality of the products.

本請求項２の発明によれば、パッドを表皮と一体発泡成形後、カップホルダーを組付けることにより、排出孔は被覆される。そのため、排出孔から反応ガスと共に発泡液が外部に漏出しても、カップホルダーによって被覆され、外部から視覚されることがない。     According to the second aspect of the present invention, the discharge hole is covered by assembling the cup holder after the pad is integrally foamed with the skin. Therefore, even if the foaming liquid leaks out together with the reaction gas from the discharge hole, it is covered by the cup holder and is not visually recognized from the outside.

以下、本発明の一実施例を図面に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１は図２に示す上面にカップホルダー３を有するアームレストの製造方法を示し、図中Ａは上型、Ｂは下型、１は上、下型Ａ、Ｂ内に収容した表皮で、この表皮１はカップホルダー３の底部に面する部分に通孔を有するように袋状に縫製されており、内側には従来のワディングが接着されていない。２はフレームを示す。   FIG. 1 shows a manufacturing method of an armrest having a cup holder 3 on the upper surface shown in FIG. 2, in which A is an upper mold, B is a lower mold, 1 is an upper and lower mold A, and a skin accommodated in B. The skin 1 is sewn in a bag shape so as to have a through hole in a portion facing the bottom of the cup holder 3, and a conventional wadding is not bonded to the inside. 2 indicates a frame.

Ｃは排出筒、Ｃ１は発泡液P1の発泡によって発生する反応ガスを外部に排出する排出孔、ＤはパッドＰ発泡成形用の発泡液P1を表皮１内に注入する漏斗を各々示す。   C denotes a discharge cylinder, C1 denotes a discharge hole for discharging reaction gas generated by foaming of the foaming liquid P1 to the outside, and D denotes a funnel for injecting the foaming liquid P1 for pad P foam molding into the skin 1.

図１に示すように、上型Ａの一部を図２に示すカップホルダー３を装着する部分まで挿着して、漏斗Ｄより、上、下型Ａ、Ｂ内に収容した表皮１内にパッド発泡成形用の発泡液P1を注入すると、発泡液P1が表皮１内において発泡する。   As shown in FIG. 1, a part of the upper mold A is inserted to the portion where the cup holder 3 shown in FIG. 2 is attached, and the funnel D is inserted into the upper skin 1 accommodated in the upper and lower molds A and B. When the foaming liquid P1 for pad foam molding is injected, the foaming liquid P1 foams in the skin 1.

この発泡液Ｐ１の発泡に伴って反応ガスが発生するが、この反応ガスは図１に示すように上方に向けた状態のガス排出孔たる排出孔Ｃ１を通って外部に排出される。
A reactive gas is generated with the foaming of the foamed liquid P1, and this reactive gas is discharged to the outside through a discharge hole C1 which is a gas discharge hole directed upward as shown in FIG.

表皮１内において発泡液P1が発泡してパッドＰを発泡成形した後、脱型して、排出孔１に対応する
表皮１の部分に、カップホルダー３を装着して図２に示すカップホルダー３付のアームレストを製造する。 The foaming liquid P1 foams in the skin 1 and foams the pad P, and then is removed from the mold, and the cup holder 3 is attached to the portion of the skin 1 corresponding to the discharge hole 1 and the cup holder 3 shown in FIG. The attached armrest is manufactured.

従って、反応ガスを排出する部分はカップホルダー３によって被覆されるので、反応ガスと共にパッド成形用の発泡液が外部に漏出しても、カップホルダー３の被覆によって外部から視覚されない。   Therefore, since the portion from which the reaction gas is discharged is covered by the cup holder 3, even if the foaming liquid for pad molding leaks to the outside together with the reaction gas, it is not visually recognized by the cover of the cup holder 3.

図３は図４に示すカップホルダー３を有しないアームレストの製造方法を示し、斯かるアームレストは一端の両側面より外部に突出する回転用支軸２がシートバック(不図示)の側面に、回転自在に取付けられるものである。   FIG. 3 shows a method of manufacturing an armrest that does not have the cup holder 3 shown in FIG. It can be attached freely.

従って、支軸２に近い部分はシートバックの側面に接合するため、アームレストをシートバック間に取付けた場合には、外部から視覚されない。
この外部から視覚されない部分に、反応ガスの排出孔D1を設けるアームレストの製造方法を図３に示す。 Accordingly, since the portion close to the support shaft 2 is joined to the side surface of the seat back, when the armrest is attached between the seat backs, it is not visually recognized from the outside.
FIG. 3 shows a method of manufacturing an armrest in which a reaction gas discharge hole D1 is provided in a portion that is not visible from the outside.

袋状に縫製した略長方体状の表皮１が、支軸２側が上部になって、上型Ａと下型Ｂ内に収容されるように、上、下型Ａ、Ｂの表皮収容用の空間部は傾斜状に形成されている。   For accommodating the upper and lower molds A and B so that the substantially rectangular skin 1 sewed in a bag shape is accommodated in the upper mold A and lower mold B with the support shaft 2 side at the top. The space is formed in an inclined shape.

従って、図４に示すパッドＰを発泡成形するパッド成形用の発泡液P1は漏斗Ｄより、上、下型Ａ、Ｂ内にセットした表皮１の注入孔Ｃ１より内部に注入される。   Therefore, a foaming liquid P1 for forming the pad P shown in FIG. 4 is injected from the funnel D into the upper and lower molds A and B through the injection hole C1 of the skin 1.

この発泡液P1の発泡による反応ガスは上型Ａに設けた排出孔D1より排気管Ｃを介して外部に排出される。   The reaction gas resulting from the foaming of the foaming liquid P1 is discharged to the outside through the exhaust pipe C from the discharge hole D1 provided in the upper mold A.

その際、排出孔Ｄ１は表皮１内の高い位置に設けてあるので、反応ガスが排気孔D1に集中して排出される。
そのため、表皮１内には反応ガスが溜まることがなく、パッドＰが表皮１と一体に図４に示すアームレストが発泡成形される。 At that time, since the discharge hole D1 is provided at a high position in the skin 1, the reaction gas is concentrated and discharged to the exhaust hole D1.
Therefore, the reaction gas does not accumulate in the skin 1, and the armrest shown in FIG.

なお、図３、図４に示す表皮１も、前記図１、図２に示す表皮１と同様に、内側に反応ガス抜き用のワディングなどの部材を接着していないものを使用する。   In addition, the skin 1 shown in FIGS. 3 and 4 is also used in the same manner as the skin 1 shown in FIGS. 1 and 2 without a member such as wadding for removing the reaction gas inside.

なお図面はいずれもアームレストを表皮一体発泡品の一例としたものであるが、ヘッドレストにも、本発明は利用できる。   In addition, although all drawings make an armrest an example of a skin-integrated foam, the present invention can also be used for a headrest.
