させる技術が開示されている。In addition, as a method for obtaining foam molded products such as automobile headrests, for example, Japanese Patent Laid-Open No. 62-5821 discloses a method in which a core is inserted into a bag-shaped outer skin material in a mold, and a liquid foam raw material is poured into the mold. A technique is disclosed in which foaming is carried out under the closed condition of the outer skin material.

確な適合性に欠け、これによって成形体の外観を悪くす
る。Regarding the production of cushioning molded bodies, the conventional method of molding the core synthetic resin foam separately requires accurate compatibility because the outer skin formed from the material sheet and the foamed molded body are separate bodies. This results in poor appearance of the molded product.
特に表皮体にファブリックを使用するときは。Especially when using fabric for the skin body.
ファブリックの持つ伸縮性によって顕著なズレを生ずる
。The elasticity of the fabric causes noticeable misalignment.

いる。On the other hand, the method disclosed in JP-A-62-5821, in which a core body and a liquid foaming material are injected into the inside of two bag-shaped outer skin materials for foam molding, uses an outer skin material made of fabric such as RA material or knitted material. If you use a fabric made from fabric or a skin material made by sewing cut fabric, the liquid foaming material will leak out through the weave and seams of the fabric and solidify, causing the appearance to deteriorate. This has the disadvantage of impairing the cushioning properties of the molded product, and thus making it impossible to provide a cushioning molded product with a comfortable range of use.
この発明はか−る現状に鑑みて、ファブリック等を表皮

備した成形体を安価に提供せんとすることを目的とした
ものである。In view of the current situation, it is an object of the present invention to provide at a low cost a molded article having a soft feeling of use and excellent cushioning properties by using fabric or the like as the skin layer.

体化させるものである。In order to achieve the above object, the present invention involves cutting a skin sheet made of fabric or natural leather 1 synthetic leather lined with a gas shielding layer, and sewing the cut fabric or the like of the skin sheet into a predetermined shape as the inside surface. After forming a skin body with a shape and pasting an adhesive tape made of polyurethane film with a thickness of 15 to 80 μm including the seam allowance to the sewn part of the backing layer side of the skin body to seal it, the skin body with the sticker pasted. The body is set in a mold, a foamed resin raw material is injected into the backing layer side, and the foamed molded body and the skin body whose surface layer is made of fabric or the like are integrated by one foam molding.

が得られるため、特に推奨されるものである。In the method of this invention, the outer surface of the skin sheet is made of fabric, natural leather, or synthetic leather, and the fabric is a cloth such as a woven fabric or a knitted fabric, and the fabric has a moderate amount of nap on the surface. It is particularly recommended because it provides a good feeling of use.
しかして、か＼るファブリックに裏打するガス遮蔽層は
、樹脂フィルム、独立気泡からなる発泡体などから構成
されるもので１発泡樹脂としてウレタン樹脂を使用する
場合には、ポリウレタンフィルムを使用してガス遮蔽層
を構成することが望ましい。However, the gas shielding layer that lines the fabric is composed of a resin film, a foam made of closed cells, etc. 1. If urethane resin is used as the foam resin, a polyurethane film is used. It is desirable to constitute a gas barrier layer.
表皮シートはこれを裁断し、ファブリック等を中表とし
て、適宜の縫い代を維持して縫合することによって所定
の外郭形状を有する表皮体を形成するが、その縫い代は
５寵前後であることが好ましい。The skin sheet is cut and sewn with fabric or the like on the inside, maintaining an appropriate seam allowance to form a skin body having a predetermined outline shape, but it is preferable that the seam allowance is around 5 cm. .
縫合による縫い代は、ファブリック等を中表として縫合
するため９表皮体裏面の裏打層に生ずるが、この裏打層
側の縫合部には前記縫い代を含めて１片面にウレタン系
若しくはアクリル形粘着剤を塗布したポリウレタンフィ
ルムからなる粘着テープを、その粘着剤面を利用して貼
着され気密に掩蔽される。A seam allowance due to stitching occurs on the lining layer on the back side of the 9 skin body because the fabric etc. is sewn with the inside facing side, but a urethane-based or acrylic adhesive is applied to one side of the seam portion on this lining layer side, including the seam allowance. An adhesive tape made of a coated polyurethane film is attached using the adhesive surface to cover the area airtight.
前記ポリウレタンフィルムは、伸縮性に冨み。The polyurethane film has great elasticity.
かつ柔軟で、縫製部の立体的な形状に追随する特徴を有
するもので、ポリエチレンなどの他の樹脂フィルムの粘
着テープでは前記特徴を有しない。It is also flexible and has the characteristic of following the three-dimensional shape of the sewn portion, which is not the case with adhesive tapes made of other resin films such as polyethylene.
特に、貼着面が発泡ウレタン樹脂又はポリウレタンフィ
ルムを使用する場合には、前記ポリウレタンフィルムか
らなる粘着テープとの結合一体化が一層強固になる特徴
を有する。In particular, when a foamed urethane resin or a polyurethane film is used as the adhesive surface, the bonding and integration with the adhesive tape made of the polyurethane film becomes even stronger.
粘着テープは、厚さが１５〜８０μ、好ましくは２０〜
３０μであって、その幅は１５鶴以上のものが好ましい
。The adhesive tape has a thickness of 15 to 80μ, preferably 20 to 80μ.
It is preferable that the width is 30μ and the width is 15 cranes or more.
か＼る粘着テープとしてブラチロン（日本リルサン■の
ポリウレタンフィルムの商品名）が特に好適に使用され
る。Brathylon (trade name of polyurethane film manufactured by Nippon Rilsan) is particularly preferably used as the adhesive tape.
このフィルムは、厚みが１５μ未満の極端に薄いものは
、フィルムに「こし」がないため、貼着時の取り扱いが
厄介であり、またフィルムの製造時にピンホールが生じ
易いため、遮蔽が完全でない場合が多い。If this film is extremely thin (less than 15 μm in thickness), it is difficult to handle when pasting because the film does not have a "tightness", and pinholes are likely to occur during film manufacturing, so the shielding is not perfect. There are many cases.
また、厚さが８０μを超えて過度のものは、貼着面に対
する追従性が乏しくなって、貼着により縫合部が引っ張
られてシワを生じたり、この引張りでしばしば剥離する
。Furthermore, if the thickness exceeds 80 μm, the adhesive will have poor conformability to the surface to which it is attached, and the sutured portion will be stretched and wrinkled due to attachment, and this tension will often cause the adhesive to peel off.
このようにして得た表皮体は、ファブリック等を表面に

この成形型内に１例えばポリウレタン、ポリスチレン、
ポリ塩化ビニル５ポリエチレンからなる発泡樹脂を注入
し発泡させる。The skin thus obtained is set in contact with the mold surface of a mold with fabric etc. as the surface, and then placed in the mold with a material such as polyurethane, polystyrene, etc.
A foamed resin consisting of polyvinyl chloride and polyethylene is injected and foamed.
これによって表皮体裏面のガス遮蔽層に所定形状の樹脂
発泡体が一体的に形成され、所期のクッション性成形体
を得ることができる。As a result, a resin foam having a predetermined shape is integrally formed on the gas shielding layer on the back surface of the skin, and a desired cushioning molded product can be obtained.

ることができる。In the method of the present invention, a skin sheet made of fabric or the like lined with a gas shielding layer is cut, and the sewn part of the skin body obtained by sewing the skin sheet with the fabric or the like side facing up is made of polyurethane of a predetermined thickness. It is covered with an adhesive tape made of film, and the foamed molded product is integrally bonded to this covered surface by foaming the resin liquid, so the backing layer prevents the liquid from seeping into the fabric, etc., and the sewn part does not become sticky. Protected by the tape, the urethane resin liquid is prevented from hardening due to impregnation into the seam allowance and from seeping out onto the fabric surface, etc., making it possible to obtain a cushion-like molded article with a good finish and a soft feel.
この発明の方法における表皮シートの裏打層。The backing layer of the skin sheet in the method of this invention.

ない優れたクッション性成形体を得ることができる。The combination of the adhesive tape and the resin liquid injected into the inside of the skin body uses a urethane resin with particularly high compatibility, so that the combination is strong and the resin liquid is molded with excellent cushioning properties without molding. You can get a body.
