- Example 1 Comparative Example 1 In Example 1, the same operation was performed except that the notch portion was not provided, the elastomer layer was not provided on the engagement element surface, and the width of the concave portion 9 of the mold was set to 12 mm. It was difficult to bend in the same plane in the lateral direction, and it was not possible to fix it in the mold recess.
- Example 2 In Example 1, the same operation as in Example 1 was performed except that the notch portion was not provided. However, although somewhat improved as compared with Comparative Example 1, the engagement element was still fixed to the mold recess. In particular, the outer diameter portion of the portion bent in the lateral direction protrudes from the concave portion of the mold, and as a result, in the molded product, the protruding portion of the locking member from the concave portion of the locking member is buried in the foamed resin. The foamable resin liquid invaded from the location and covered the surface of the elastomer layer. As a result, the elastomer layer on the surface could not be peeled off at the same portion, and the engagement function was lost.
- Example 3 In Example 1, the same operation as in Example 1 was performed except that the surface of the engaging element was not provided with an elastomer layer and the mold recess width was 12 mm. As a result, the locking member could not be fixed in the recess, and when it was forcibly bent and inserted, both end portions in the length direction had an engaging function, but in the width direction as in Comparative Example 2 above. The outer diameter portion that is bent in the lateral direction in the plane is lifted from the concave portion of the mold and buried in the foamed resin, and the engagement function is lost.
- Example 2 A cushion having a locking member in the same manner as in Example 1 except that the cutout portion (wedge shape) is a simple cut (the thickness of the cutting blade is 0.2 mm and there is no wedge-shaped cutout portion).
- the cutout portion is a simple cut (the thickness of the cutting blade is 0.2 mm and there is no wedge-shaped cutout portion).
- the mold-in molding locking portion of the present invention can fix a locking member at a predetermined position on the surface of a foamed resin molded body having a complicated curved surface shape, such as a high-grade automobile sheet. It can be used for airplane seats, particularly for luxury automobile seats.
Abstract
Description
該係止部材付き発泡樹脂成形体は、その表面を布で代表される被覆体で蔽い、被覆体裏面に存在する被係合素子と該係止部材の係合素子を係止させることで発泡樹脂成形体に被覆体を固定して、座席シート等に使用される。
自動車用シートの成形方法として、表面に多数の係合素子、裏面に多数の埋設素子(アンカー素子と称す)を備えた係止部材を成形型内の所定の位置にセットし、該成形型内に成形用樹脂(発泡性樹脂液)を注入して発泡させ、上記係止部材のアンカー素子を発泡樹脂成形体内に埋設させて発泡樹脂成形体と係止部材を一体化し、かつ上記係合素子が発泡樹脂成形体の外表面に露出するように係止部材を発泡樹脂成形体に埋め込み成形する方法(いわゆるモールドイン成形法)が用いられている。
そして、シートカバー(被覆体)の裏面には、上記係止部材の係合素子に係合可能な被係合素子が設けられており、この被係合素子と発泡樹脂成形体表面の係合素子を係合させることにより、上記シートカバーを発泡樹脂成形体に沿わせ、発泡樹脂成形体はシートカバーにより被覆固定される。
したがって、モールドインの成形技術においては、該係合素子面に樹脂液が浸入して係合素子が樹脂中に埋没することを阻止することが必要である。
すなわち本発明は、帯状の基板の片面に係合素子群を有し、かつ該係合素子群がエラストマー層で覆われており、さらに該基板には、幅方向中央部から幅方向端部に至る切目または切欠部を複数有しているモールドイン成形用係止部材である。
さらに本発明において、基板の係合素子群を有している面の幅方向両端部にエラストマー層により覆われていない部分が存在している場合、また基板の係合素子が存在する面に対して反対側の面に、アンカー材またはアンカー素子が設けられている場合、また該エラストマー層が該基板とは相違する色調を有している場合、エラストマー層には、切目または切欠部が存在していない場合、のいずれでも好ましいことを見出した。
以上のことから本発明では、係合素子群の上を覆うエラストマー層と、係止部材の幅方向に入れた切目または切欠部が、共同で複雑な二次元や三次元の曲面形状に対応した変形を可能にするという効果をもたらしている。

これらの図から明らかなように、基板1の表面には係合素子2、裏面には図1ではアンカー材3、図2ではアンカー素子3を有しており、そして、係合素子2を覆うようにエラストマー層4が基板表面上に存在しており、係合素子2はこのエラストマー層4中に埋没している。そして、基板1には、幅方向中央部から幅方向端部に至る切目または切欠部5および5’を複数有している。
基板1は、その表面に存在する係合素子及び裏面にアンカー素子が存在している場合にはアンカー素子も含めて、これらはともに同一の樹脂から形成されているのが、製造の上から、さらに係合素子やアンカー素子の耐剥離性の点で好ましい。
基板1は、幅5~20mmが好ましく、より好ましくは6~15mm、さらに好ましくは7~12mmである。基板の幅が大き過ぎると複雑な三次元形状に曲げることが難しくなる。逆に、細すぎてもその上に存在させる係合素子の数が少なくなり、係合力が劣ることとなる。また基板1の厚さとしては、0.1~1mmが好ましく、より好ましくは0.3~0.7mmである。基板の厚さが薄すぎる場合には強度的に問題を生じ、また厚すぎる場合には複雑な三次元形状に曲げることが困難となる。
なお、アンカー材およびアンカー素子3は係止部材の長さ方向に連続して存在していてもよいし、また係合素子2のように、係止部材の長さ方向に不連続で存在していてもよい。
かかる樹脂として、ポリエチレン、ポリプロピレン等のポリオレフィン系、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリ乳酸等のポリエステル系、ナイロン6、ナイロン66等のポリアミド系等の熱可塑性樹脂が挙げられるが、中でもポリオレフィン系樹脂、特にポリプロピレンが好ましく用いられる。
またアンカー材として布帛を用いる場合には、該布帛は通常の天然、合成、再生繊維からなる比較的粗な構造を有する布帛を用いることができる。比較的粗な構造を有する布帛を用いれば、発泡性樹脂液が布帛の組織内に浸透して係止部材と発泡樹脂成形体との剥離強度を高めることとなる。
なお、基板には後述するように切目または切欠部が設けられるが、基板に設けた切目または切欠部に連続してエラストマー層にも切目または切欠部が設けられていてもよいし、またそのような切目または切欠部がエラストマー層に設けられていなくてもよい。エラストマー層にも基板層に連続する切目または切欠部が設けられている場合には、発泡性樹脂液が、基板層の切目または切欠部からエラストマー層の切目または切欠部にまで侵入して、エラストマー層を取り除いた後においても係合素子面に発泡樹脂が残ることがあり、これが係合素子の係合力を低下させる場合がある。
なお、モールドインファスナーにおいて、係止部材の係合素子面をゴム等のエラストマーで覆い、モールドイン成形後に該エラストマーを除去して係合素子が発泡樹脂で覆われることを防止する技術に関しては公知である(例えば、特表平9-506559号や特表平6-501187号)。しかしながら、単にエラストマーで覆うだけでは複雑な二次元や三次元形状に追随して変形させて対応することが可能な係止部材とはなり得ない。
そこで、本発明では、前述したように、係合素子群の上を覆うエラストマー層と、係止部材の幅方向に入れた切目、または切欠部を有する構成としたことによって、これらが共同で複雑な二次元や三次元の曲面形状に対応可能になるという効果をもたらすものである。
成形型8の内部に設けられた成形型凹部9に、本発明のモールドイン成形用係止部材6を、エラストマー層4により被覆された係合素子2が凹部底部側となるように凹部内部に収容配置する。本発明において、金型内に設置された凹部は三次元的に複雑に曲がっている場合には、本発明の係止部材は特に効果を発揮する。従来は、凹部が左右方向に曲がっている場合には係止部材を短く切断して、金型凹部の曲がりに合わせてこの短い係止部材を複数本嵌めていた。しかしながら、本発明の係止部材6は、前後(厚み方向)のみならず左右方向(幅方向)にも曲げ易く、1本の係止部材で金型凹部の左右方向への曲がりにも対応できることから、金型凹部への係止部材のセット速度においてはるかに優れ、作業能率を格段に向上することができる。
酸化チタンを0.5重量%含有するポリプロピレン樹脂にオレフィン系エラストマー(住友化学株式会社製V0131)を10重量%添加したポリプロピレン系樹脂組成物を用いて、図3に示すような断面形状で、基板1及びその表面側に係合素子2、さらに基板裏面側にアンカー素子3が形成されるように、対応したスリットを有する押出口金より押出成形し、得られた帯状の成形物に係合素子2となる突出部分のみに0.3mm間隔で突出部分の根元まで切れ目を入れ、しかる後長さ方向に3倍延伸することにより、モールドイン成形用係止部材の本体部Mを製造した。
実施例1において、切欠部を設けることなく、かつ係合素子表面にエラストマー層を設けず、さらに金型の凹部9の幅を12mmとした他は同一の操作を行ったところ、係止部材を横方向に同一面内で曲げることが難しく、金型凹部に固定することができなかった。
実施例1において、切欠部を設けない以外は実施例1と同様の操作を行ったところ、比較例1と比べると幾分改善されているものの、それでも係合素子を金型凹部に固定することが難しく、特に横方向に曲げた個所は外径部分が金型凹部からはみ出し、その結果、成形品において、係止部材の金型凹部からのはみ出し個所は、発泡樹脂中に埋没し、さらにその個所から発泡性樹脂液が侵入してエラストマー層表面を覆い、その結果、同部分では表面のエラストマー層を剥離することができず、係合機能を喪失していた。
実施例1において、係合素子表面にエラストマー層を設けず、さらに金型凹部幅を12mmとした他は実施例1と同一の操作を行った。その結果、係止部材を凹部に固定することができず、無理に曲げて挿入したところ、長さ方向両端部は係合機能を有していたが、上記比較例2と同様に、幅方向平面内で横方向に曲げているところの外径部分が金型凹部から浮き上がり、発泡樹脂中に埋没し、係合機能を喪失していた。
実施例1において、切欠部(楔型)を単なる切目(切断刃の厚みが0.2mmで、楔型の切り取り部分なし)とした以外は実施例1と同様にして、係止部材を有するクッションを作製した。その結果、実施例1の場合と比べて、横方向への曲がり性の点で実施例1よりわずかに劣っていたものの、上記比較例のいずれの場合と比べても、はるかに三次元追従性に優れ、金型凹部に装着できた。そして、発泡性樹脂液を金型内に充填してクッションを作製したところ、エラストマー層表面は殆ど発泡ウレタンで覆われておらず、係合素子を覆うエラストマー層を端から簡単に係合素子面から剥がすことができた。そして、基板幅方向両端部は発泡ポリウレタン中に埋没しており、この両端部と裏面に存在するアンカー素子により、エラストマー層を剥がす方向の力を多少手荒く加えても、係止部材がクッションから剥がれるということが全くなかった。
