Description

本発明は、車両用座席シートに使用されるシート用パッドの製造方法に関するものである。   The present invention relates to a method for manufacturing a seat pad used in a vehicle seat.

車両用座席シートに使用されるパッドとしては、通常モールド成形された軟質ポリウレタンフォームが使用される。係る軟質ポリウレタンフォームは、シートへの装着のためのインサート金具、座席シートの表皮材を装着するための面ファスナー、パッドと取付金具との摺動により発生する異音防止を主目的とする所定形状に切り抜かれた不織布製の成形基布などを成形金型に装着した状態で成形キャビティーに軟質ポリウレタンフォームを形成する発泡原液組成物を供給して成形金型内で発泡硬化させ、これらの部材を一体化することにより製造される。   As a pad used for a vehicle seat, a soft polyurethane foam that is usually molded is used. The flexible polyurethane foam has a predetermined shape mainly intended to prevent noise generated by sliding between an insert fitting for mounting on a seat, a hook-and-loop fastener for attaching a skin material of a seat seat, and a pad and a mounting bracket. These components are made by supplying a foamed stock solution composition that forms a flexible polyurethane foam into a molding cavity in a state in which a non-woven fabric molding base fabric or the like that has been cut out is attached to the molding die, and foaming and curing in the molding die. It is manufactured by integrating.

軟質ポリウレタンフォーム製のシート用パッドとしては、座面部とその両側に形成された凸状のサイド部を有するものも多く使用されており、係るサイド部と座面部とを異なる硬度の軟質ポリウレタンフォームで形成する技術は公知である（例えば特許文献１）。
特開２００４−１７４７６２号公報 Many seat pads made of flexible polyurethane foam have a seating surface part and convex side parts formed on both sides thereof, and the side part and the seating surface part are made of soft polyurethane foam having different hardness. The forming technique is known (for example, Patent Document 1).
JP 2004-174762 A

しかし、シート用パッドのサイド部のごく一部を部分的に硬度を高くしたい場合があり、特許文献１の方法では、係る要請に対応することができない。シート用パッドのサイド部の一部を部分的に硬度を高くする技術としては、軟質ポリウレタンフォームよりさらに硬度の高い小さな部材、とりわけ軽量性を考慮した所定形状の発泡体ブロックを係るサイド部の必要部分に埋設して性能を改善する方法が考えられ、係る構成のシート用パッドの製造には、上記の発泡体ブロックを成形基布などと共に１構成部材として成形金型に装着し、発泡原液組成物を供給して発泡硬化させてシート用パッドとする方法が一般的である。   However, there is a case where it is desired to partially increase the hardness of only a part of the side portion of the seat pad, and the method of Patent Document 1 cannot meet such a request. As a technique for partially increasing the hardness of a part of the side portion of the seat pad, the side portion needs a small member having a higher hardness than that of the flexible polyurethane foam, in particular, a foam block having a predetermined shape considering light weight. A method of improving the performance by embedding in a part is considered. For the production of a sheet pad having such a structure, the foam block is mounted as a constituent member together with a molding base fabric and the like on a molding die, and a foaming stock solution composition A method is generally used in which a product is supplied and foam-cured to form a pad for a sheet.

シート用パッドの製造工程は、金型を開いた状態で上述の種々の部材を装着する部材装着工程、軟質ポリウレタンフォームを形成する発泡原液組成物を注入する注入工程、金型を閉じて発泡硬化させる成形工程、金型を開いて成形品であるシート用パッドを取り出す脱型工程、金型の内部を清掃して離型剤を塗布する準備工程が連続して行われる循環式の製造ラインとなっており、部材装着工程には隣接して注入工程が設けられていて、成形金型は該ライン上を一定速度で移動するように構成されている。そのため部材装着工程の時間は限られたものであり、成形金型に装着する部材の数を増加させると、装着時間が不足するという問題が発生する。部材の装着時間を確保するために部材装着工程と注入固定との間隔を広くすることやライン速度を遅く設定することは可能であるが、設備の変更が必要であって費用がかかるという問題やシート用パッドの製造サイクルタイムが長くなり、全体としてシート用パッドの製造コストが高くなるという問題を生じ、好ましいものではない。   The sheet pad manufacturing process includes a member mounting process in which the above-described various members are mounted in a state where the mold is opened, an injection process in which a foaming stock solution composition for forming a flexible polyurethane foam is injected, and the mold is closed and foam-cured. A recycle-type production line in which a molding process, a demolding process for opening a mold and taking out a sheet pad as a molded product, a preparatory process for cleaning the inside of the mold and applying a release agent are continuously performed An injection step is provided adjacent to the member mounting step, and the molding die is configured to move on the line at a constant speed. Therefore, the time for the member mounting process is limited, and if the number of members to be mounted on the molding die is increased, the problem of insufficient mounting time occurs. Although it is possible to widen the interval between the member mounting process and the injection fixing and to set the line speed slower in order to secure the member mounting time, it is necessary to change the equipment, which is expensive. The manufacturing cycle time of the sheet pad becomes long, and the manufacturing cost of the sheet pad increases as a whole, which is not preferable.

本発明は、発泡体ブロックを埋設したシート用パッドを、成形金型に装着する部材数を増加させることなく製造するシート用パッドの製造方法を提供することを目的とするものである。   An object of this invention is to provide the manufacturing method of the sheet | seat pad which manufactures the pad for sheets which embed | buried the foam block without increasing the number of members with which a shaping die is mounted | worn.

本発明は、成形金型の内面に少なくとも不織布にて成形された成形基布を装着し、軟質ポリウレタンフォームを形成する発泡原液組成物を供給して成形金型内で発泡硬化させて前記成形基布層を有するシート用パッドとするシート用パッドの製造方法であり、
前記成形基布が、所定位置に前記軟質ポリウレタンフォームより硬度の高い発泡体ブロックを装着した複合成形基布であることを特徴とする。 The present invention provides a molding base fabric formed of at least a nonwoven fabric on the inner surface of a molding die, supplies a foaming stock solution composition for forming a flexible polyurethane foam, and foams and cures in the molding die to form the molding base. It is a method for manufacturing a sheet pad to be a sheet pad having a fabric layer,
The molded base fabric is a composite molded base fabric in which a foam block having higher hardness than the flexible polyurethane foam is mounted at a predetermined position.

係る製造方法によれば、発泡体ブロックは予め成形基布に固定して複合成形基布としてシート用パッドの製造ラインに供給されるので、シート用パッドの製造に使用する部材の数を低減することができる。その結果、製造設備の変更や製造サイクルタイムの延長などの問題を起すことなく部材の増加したシート用パッドを製造することができる。   According to this manufacturing method, since the foam block is fixed to the molding base fabric in advance and supplied to the sheet pad manufacturing line as a composite molding base fabric, the number of members used for manufacturing the sheet pad is reduced. be able to. As a result, it is possible to manufacture a sheet pad having an increased number of members without causing problems such as changes in manufacturing facilities and an increase in manufacturing cycle time.

また発泡体ブロックを成形基布に装着することによって、例えば金型、特に上型に形成された係止ピンに係止して配設した場合に、金型の閉鎖などの動きによって発泡体ブロックが脱落し、その状態で発泡原液組成物が供給されて不良品が発生するという問題も解消される。   In addition, by mounting the foam block on the molding base fabric, for example, when the foam block is locked to a locking pin formed on the mold, particularly the upper mold, the foam block is moved by the movement of the mold, etc. Is eliminated, and the foaming stock composition is supplied in this state, thereby causing a problem that defective products are generated.

上記のシート用パッドとするシート用パッドの製造方法においては、前記複合成形基布は、ポケット形成基布を縫着して形成したポケットに前記発泡体ブロックを収容したものであることが好ましい。   In the sheet pad manufacturing method as the above-described sheet pad, the composite molded base fabric is preferably one in which the foam block is accommodated in a pocket formed by sewing a pocket forming base fabric.

係る構成の複合成形基布は、簡単に低コストにて製造することができる。   The composite molded base fabric having such a configuration can be easily manufactured at low cost.

本発明における成形基布を構成する繊維材料としては、シート用パッドにおいて使用される公知の基布を限定なく使用することができ、とりわけポリエステル繊維、ポリプロピレン繊維などの不織布の使用が好ましい。   As the fiber material constituting the molded base fabric in the present invention, known base fabrics used in sheet pads can be used without limitation, and the use of nonwoven fabrics such as polyester fibers and polypropylene fibers is particularly preferable.

本発明における発泡体ブロックを構成する材料としては、公知の樹脂発泡体が限定なく使用可能であり、具体的には軟質、半硬質、ないし硬質のポリウレタンフォーム、ポリエチレンフォーム、ポリプロピレンフォーム、ポリスチレンフォーム、ＥＶＡフォーム、フェノール樹脂フォームなどが例示される。所定形状の発泡体ブロックは、モールド成形により成形されたものであってもよく、スラブフォームから裁断により形成したものであってもよい。   As the material constituting the foam block in the present invention, known resin foams can be used without limitation, specifically, soft, semi-rigid or rigid polyurethane foam, polyethylene foam, polypropylene foam, polystyrene foam, Examples include EVA foam and phenol resin foam. The foam block having a predetermined shape may be molded by molding or may be formed by cutting from a slab foam.

図１は、本発明のシート用パッドの製造方法において、成形金型に複合成形基布を装着した状態を示した斜視図である。縫製を行い、発泡体ブロックを装着した複合成形基布１０は、上型４３と下型４１とがヒンジにて開閉自在に固定された成形金型４６の上型４３に、係止ピン１３にて係止、装着されている。下型４１には、他のシート用パッド構成部材の例であるインサート金具４５が配設されている。これ以外の部材、例えば面ファスナーなどが配設されていてもよい。この状態で下型４１に軟質ポリウレタンフォームを形成する発泡原液組成物を所定量供給し、金型を閉じて発泡原液組成物を発泡硬化させるとインサート金具４５、複合成形基布１０等が一体化されたシート用パッドが形成される。   FIG. 1 is a perspective view showing a state in which a composite molding base fabric is mounted on a molding die in the sheet pad manufacturing method of the present invention. The composite molded base fabric 10 that has been sewn and mounted with a foam block is attached to the upper die 43 of the molding die 46 in which the upper die 43 and the lower die 41 are fixed by a hinge so as to be opened and closed. Locked and mounted. The lower mold 41 is provided with an insert fitting 45 that is an example of another sheet pad constituent member. Other members, such as hook-and-loop fasteners, may be provided. In this state, when a predetermined amount of the foamed stock solution composition for forming the flexible polyurethane foam is supplied to the lower mold 41 and the foamed stock solution composition is foamed and cured by closing the mold, the insert fitting 45, the composite molded base fabric 10 and the like are integrated. A sheet pad is formed.

複合成形基布１０は、所定形状に形成された成形基布を、装着する上型の形状に沿った立体形状となるように必要部分が縫製され、発泡体ブロックが装着される。発泡体ブロックの成形基布への装着固定は、接着剤、粘着剤、両面粘着テープ等を使用して行ってもよいが、上述のように、ポケット形成基布を縫着して形成することが、立体形状への縫製加工と同じ縫製装置を使用して行えるので新たな接着剤塗布設備などの設置が不要であり、簡便に低コストにて行うことができ、好ましい。   The composite molded base fabric 10 is sewn at a necessary portion so that the molded base fabric formed into a predetermined shape has a three-dimensional shape along the shape of the upper mold on which the molded base fabric is mounted, and the foam block is mounted. Attaching and fixing the foam block to the molded base fabric may be performed using an adhesive, a pressure-sensitive adhesive, a double-sided adhesive tape, etc., but as described above, the pocket-forming base fabric should be sewn and formed. However, since it can be performed using the same sewing apparatus as that for sewing into a three-dimensional shape, it is not necessary to install a new adhesive application facility and the like, which can be easily performed at low cost, and is preferable.

図２は、発泡体ブロック２１をポケット１２を形成して成形基布２３に装着した形状を例示した平面図である。成形基布２３は、裁断により形成してもよく、トムソン刃などを使用して打ち抜いて形成してもよい。成形基布２３は、１６にて例示した破線部を縫合することによって上型の凹凸に沿った立体的な形状に加工される。また本発明においては、成形基布２３の所定位置に発泡体ブロックを収容したポケット１２を設け、複合成形基布１０として使用する。ポケット１２を構成するポケット形成基布は、成形基布２３と同一材料であってもよく、異なる基布であってもよいが、同一基布を使用することが好ましい。発泡体ブロック２１の中央に形成された孔１４は縫製後の複合成形基布１０を図１に例示したような金型に装着する際の係止ピンに挿着するための係止孔である。成形基布の小孔１５は、ポケット１２の縫製位置を示すものである。孔１４、１５は、成形基布２３を打ち抜き加工により形成するときには打ち抜き加工時に同時に打ち抜き形成してもよく、打ち抜き加工や裁断加工により形成される場合には別途加工工程を設けて形成してもよい。   FIG. 2 is a plan view illustrating a shape in which the foam block 21 is formed in the pocket 12 and attached to the molded base fabric 23. The molded base fabric 23 may be formed by cutting, or may be formed by punching using a Thomson blade or the like. The molded base fabric 23 is processed into a three-dimensional shape along the unevenness of the upper mold by stitching the broken line portion exemplified in 16. In the present invention, the pocket 12 containing the foam block is provided at a predetermined position of the molded base fabric 23 and used as the composite molded base fabric 10. The pocket forming base fabric constituting the pocket 12 may be the same material as the molded base fabric 23 or a different base fabric, but it is preferable to use the same base fabric. A hole 14 formed in the center of the foam block 21 is a locking hole for inserting the composite molded base fabric 10 after sewing into a locking pin when mounting the mold base illustrated in FIG. . The small hole 15 of the molded base fabric indicates the sewing position of the pocket 12. The holes 14 and 15 may be formed by punching at the same time as the forming base fabric 23 by punching, or may be formed by providing a separate processing step when formed by punching or cutting. Good.

図３は、発泡体ブロック２１を収容して閉鎖したポケット１２の図２のＸ−Ｘ断面図である。ポケット１２は、基布２３の４個の孔１５にて指定される所定位置にポケット形成基布２５を縫製により固定して形成される。ポケット１２には発泡体ブロック２１が収容されている。発泡体ブロック２１には孔２９が形成され、成形基布２３には発泡体ブロック２１の係止孔２９位置に孔２７が形成されており、複合成形基布１０を成形金型に装着したときに、金型に立設された係止ピンに係止されて、発泡原液組成物の発泡の際の液の動きによって発泡体ブロックの位置が変動することを防止する作用を奏する。   FIG. 3 is a cross-sectional view taken along the line XX of FIG. 2 of the pocket 12 that houses and closes the foam block 21. The pocket 12 is formed by fixing the pocket forming base cloth 25 at a predetermined position designated by the four holes 15 of the base cloth 23 by sewing. A foam block 21 is accommodated in the pocket 12. A hole 29 is formed in the foam block 21, and a hole 27 is formed in the molded base fabric 23 at the position of the locking hole 29 of the foam block 21. When the composite molded base fabric 10 is mounted on a molding die, In addition, it is locked to a locking pin erected on the mold, and has an effect of preventing the position of the foam block from fluctuating due to the movement of the liquid during foaming of the foamed stock solution composition.

図４はポケット形成基布の展開図であり、図５はポケット形成基布を折り曲げて成形基布に逢着して一方が開口状態のポケットを形成し、該ポケット内に発泡体ブロック２１を収容する状態を示した斜視図である。発泡体ブロック２１は、矢印方向に収容し、開口部のポケット形成基布の基布２６を折り曲げて開口を閉鎖し、２７に沿って縫着して発泡体ブロック２１を収容したポケット１２とする。   FIG. 4 is a development view of the pocket forming base fabric, and FIG. 5 is a view showing that the pocket forming base fabric is folded and attached to the molded base fabric to form a pocket with one open, and the foam block 21 is accommodated in the pocket. It is the perspective view which showed the state to do. The foam block 21 is accommodated in the direction of the arrow, the pocket forming base fabric 26 of the opening is folded to close the opening, and sewn along 27 to form the pocket 12 containing the foam block 21. .

ポケット形成基布の壁面を構成する面の中央近傍には、穴３０が形成されている。この穴３０は、発泡硬化の際の発泡原液組成物が収容された発泡体ブロックと接触し、一体に接着硬化するためのものであり、係る接着の結果、発泡体ブロック２１がシート用パッドの内部で固定され、力を受けたときに動くという問題が解消される。穴３０を形成せずに発泡体ブロック２１をポケット１２内に密閉すると、接着固定されない結果、発泡体ブロック２１がポケット内で動き、シートとして違和感を生じるものとなる。   A hole 30 is formed in the vicinity of the center of the surface constituting the wall surface of the pocket forming base fabric. This hole 30 is for contacting the foam block containing the foamed stock solution composition during foam curing and integrally bonding and curing. As a result of the adhesion, the foam block 21 is formed on the sheet pad. The problem of being fixed inside and moving when receiving force is eliminated. If the foam block 21 is sealed in the pocket 12 without forming the hole 30, the foam block 21 moves in the pocket as a result of not being bonded and fixed, resulting in an uncomfortable feeling as a sheet.

図６は、サイド部に発泡体ブロックを埋設したシート用パッドの正面図とサイド部を例示した部分断面図である。シート用パッド５０は座面部５４と該座面部の両サイドに形成された凸状のサイド部を有し、座面部にはインサート金具４５が、サイド部には発泡体ブロック２１が、裏面側には成形基布２３が、それぞれ埋設ないし接着により一体化されている。   FIG. 6 is a front view of a sheet pad in which a foam block is embedded in the side portion and a partial cross-sectional view illustrating the side portion. The seat pad 50 has a seat surface portion 54 and convex side portions formed on both sides of the seat surface portion, the insert metal fitting 45 on the seat surface portion, the foam block 21 on the side portion, and the back surface side. The molding base fabric 23 is integrated by embedding or bonding.
