Abstract
Description
本発明は自動車用シートのシートバック製造方法に関する。 The present invention relates to a method for manufacturing a seat back of an automobile seat.
従来の自動車用シートには、着座面側の左右に隆起部を有する発泡体製パッドに、その着座面の形状に一致するように表皮材を成形と同時に着座面に接着するいわゆる成形接着シートがある。 A conventional automobile sheet has a so-called molded adhesive sheet that adheres to a seating surface at the same time as forming a skin material on a foam pad having raised portions on the left and right sides of the seating surface so as to match the shape of the seating surface. is there.
この成形接着シートは上、下金型の一方にパッド、他方に表皮材を取付けて、表皮
材を加熱しパッドに加圧したり、或いは、上、下金型の一方に載置した表皮材を金型
面に真空吸引し、その表皮材にパッドを加圧して接着している(例えば特開平７−１５８８号公報)。
This molded adhesive sheet has a pad attached to one of the upper and lower molds, and a skin material attached to the other, and the skin material is heated and pressurized to the pads, or a skin material placed on one of the upper and lower molds A vacuum is applied to the mold surface, and a pad is pressed and bonded to the skin material (for example, JP-A-7-1588).
従って、従来の成形接着シートは上、下金型を使用して表皮材をパッドに成形接着している。 Therefore, in the conventional molded adhesive sheet, the skin material is molded and bonded to the pad using the upper and lower molds.
従って、この成形接着シートが例えばシートバックの場合においては、パッドの前面側に表皮材を成形接着した後、表皮材の端末をパッドの背面に固定し、その後、その背面をバックボードで被覆する必要があり、バックボードは合成樹脂材で凹凸状に成形し、パッドの背面側に設けた剛性部材に固定している。 Therefore, when this molded adhesive sheet is, for example, a seat back, after the skin material is molded and bonded to the front surface side of the pad, the end of the skin material is fixed to the back surface of the pad, and then the back surface is covered with the backboard. The backboard is formed in a concavo-convex shape with a synthetic resin material and fixed to a rigid member provided on the back side of the pad.
そのため、前記従来品は接着後の表皮材における端末の固定作業と、凹凸状に成形したバックボードの取付作業によって、シートバックの製造効率が頗る悪い不具合があった。 For this reason, the conventional product has a problem in that the manufacturing efficiency of the seat back is poor due to the fixing operation of the terminal on the skin material after bonding and the mounting operation of the backboard formed into a concavo-convex shape.
そこで、本発明は表皮材をパッドの前面に成形接着して製造するシートバックにおいて、その製造効率を向上させることである。 Accordingly, the present invention is to improve the manufacturing efficiency of a seat back manufactured by molding and bonding a skin material to the front surface of a pad.
以上の目的を達成するための本発明に係るシートバックの製造方法は、シートバックの略外形形状にモールド成形した発泡体製パッド及びこのパッドを内部に装着しパッドの外形に対して大径の袋状に形成した外被部材を有し、この外被部材はパッドの前面に接着される表皮材と、この表皮材に縫着され熱硬貨性合成樹脂を含浸させた成形不織布製のバックボード材とから構成し、
前記表皮材を、表面成形型で、パッドの前面に加圧、加熱して接着して表皮を形成するし、
前記バックボード材を、背面成形型で加熱、吸引してバックボードを成形し、
前記表面成形型と背面成形型は、上下一対の金型で構成してなることを特徴とするものである。
In order to achieve the above object, a seat back manufacturing method according to the present invention includes a foam pad molded into a substantially outer shape of the seat back and a pad having a large diameter with respect to the outer shape of the pad. A cover member formed in a bag shape, the cover member being bonded to the front surface of the pad, and a backboard made of molded non-woven fabric that is sewn to the cover member and impregnated with a thermo-coin synthetic resin Composed of materials,
The skin material is a surface molding die, pressed and heated on the front surface of the pad, and bonded to form a skin,
The backboard material is heated and sucked with a back mold to form a backboard,
The surface molding die and the back molding die are constituted by a pair of upper and lower molds.
そして、前記表面成形型と背面成形型とによって、前記表皮材を成形、接着して表皮を形成すると略同時にバックボードを成形するようにするのが好ましい。 Then, it is preferable to form the backboard substantially simultaneously with the surface molding die and the back molding die when the skin material is molded and bonded to form the skin.
本発明によれば、表皮材を成形しパッドの前面に接着する表面成形型と、バックボードを加熱、吸収して成形する背面成形型が、上下一対の金型で構成されているため、パッドに対する表皮材、バックボードの取付が容易になり、シートバックの製造効率を向上し得る。 According to the present invention, the surface molding die that forms the skin material and adheres to the front surface of the pad, and the back surface molding die that heats and absorbs the backboard and is formed by a pair of upper and lower molds. It becomes easy to attach the skin material and the back board to the seat, and the manufacturing efficiency of the seat back can be improved.
即ち、従来品の如く、上、下型で表皮材をパッドに接着し、脱型後、あらかじめ、所定形状に成形したバックボードをパッドに固定する必要がない。 That is, unlike the conventional product, it is not necessary to bond the skin material to the pad with the upper and lower molds, and to fix the backboard formed in a predetermined shape to the pad in advance after demolding.
また、パックボードが合成樹脂材を含浸させた成形不織布で形成しているため、外被部材を構成する表皮材、バックボードを所定形状に成形する前に、一体に袋状に縫製でき、この袋状の外被部材は成形前の状態で縫着されているため、シートバックの略外形形状にモールド成形した発泡体製パッドの外形に対して大径になり、パッドが内部に装着し易い。そして、成形後は各部材が収縮してパッドの外面に皺、タルミなく密着される。 In addition, since the pack board is formed of a molded nonwoven fabric impregnated with a synthetic resin material, it can be sewn together into a bag shape before the skin material and the back board constituting the outer cover member are molded into a predetermined shape. Since the bag-shaped jacket member is sewn in a state before molding, it has a large diameter with respect to the outer shape of the foam pad molded into the substantially outer shape of the seat back, and the pad can be easily mounted inside. . Then, after molding, each member contracts and adheres to the outer surface of the pad without wrinkles or sagging.
加えて、前記表皮材とバックボードの成形を同時に行うことにより、より速やかにシートバックが製造できる。 In addition, a seat back can be manufactured more quickly by simultaneously forming the skin material and the backboard.
以下、図面に基づいて、本発明の一実施例を説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
図１は表皮材３、バックボード４を成形する前の状態を示し、この表皮材３´は従来シートバックに使用されている材質からなるものであり、パックボード材４´は熱硬化性合成樹脂を含浸させた成形不織布で、例えば、実開平７−１５４４８号に開示されている材質で成形されているものを使用している。 FIG. 1 shows a state before the skin material 3 and the backboard 4 are molded. The skin material 3 'is made of a material conventionally used for a seat back, and the pack board material 4' is a thermosetting synthetic material. A molded non-woven fabric impregnated with resin, for example, one molded with the material disclosed in Japanese Utility Model Laid-Open No. 7-15448 is used.
この表皮材３´とバックボード材４´は成形する前に一体に袋状に縫着され、これを外被部材Ａとする。
この袋状の外被部材Ａ内に、シートバックの略外形形状にモールド成形した発泡体製パッド５が装着される。
The skin material 3 ′ and the backboard material 4 ′ are sewn together in a bag shape before forming, and this is referred to as a jacket member A.
A foam pad 5 molded in a substantially outer shape of a seat back is mounted in the bag-shaped outer cover member A.
以上の外被部材Ａは成形後収縮するため、あらかじめ、パッド５の外形形状に対して大径に縫着されている。そのため、この外被部材Ａ内にパッド５が容易に装着できる。
なお、パッド５にはフレーム６、ばね（不図示）などが取付けられている。
Since the jacket member A described above shrinks after molding, it is previously sewn to a large diameter with respect to the outer shape of the pad 5. Therefore, the pad 5 can be easily mounted in the jacket member A.
The pad 5 is attached with a frame 6 and a spring (not shown).
図中１は上金型たる表面成形型、２は下金型たる背面成形型を各々示す。 In the figure, reference numeral 1 denotes a surface mold as an upper mold, and 2 denotes a back mold as a lower mold.
以上の表面成形型１は表皮材３´を加熱してパッド５の前面に接着する金型で、表皮材３´の裏面にはホットメルト接着剤が設けてあり、表面成形型１で加熱することにより溶融して表皮材３´をパッド５の前面に接着して表皮３が成形接着されるように構成されている。 The surface molding die 1 described above is a mold that heats the skin material 3 ′ and adheres it to the front surface of the pad 5. A hot melt adhesive is provided on the back surface of the skin material 3 ′ and is heated by the surface molding die 1. Thus, the outer skin 3 is bonded to the front surface of the pad 5 by melting and the outer skin 3 is formed and bonded.
なお、パッド５の前面左右には隆起状のサイド部が突出し、このパッド５の前面形状に一致するように、表面成形型１の加圧面が形成されている。 Note that protruding side portions protrude from the left and right sides of the front surface of the pad 5, and the pressing surface of the surface mold 1 is formed so as to match the front surface shape of the pad 5.
従って、表面成形型１で表皮材３´を加熱しパッド５に加圧することにより、図２に示すように、表皮３はパッド５の前面に沿う形状に成形されて接着される。 Therefore, by heating the skin material 3 ′ and pressurizing the pad 5 with the surface molding die 1, the skin 3 is molded and bonded to the shape along the front surface of the pad 5 as shown in FIG. 2.
一方、背面成形型２は真空成形型でその型面には多数の給排気機能を有する通気孔２０、２０…が開孔され、成形前のバックボード材４´を型面に沿って吸引することにより型面に沿った形状にバックボード４を成形する構造である。 On the other hand, the back surface mold 2 is a vacuum mold, and a large number of vent holes 20, 20,... Thus, the back board 4 is formed into a shape along the mold surface.
そして、この背面成形型２は吸引する前に、前記バックボード材４´の熱硬化性の合成樹脂材が溶融してバックボード材４´が非通気性を有し、背面成形型２の型面に吸着されるように、金型自体を加熱するか、或いは、前記通気孔２０、２０より熱風を送風して、前記合成樹脂材を溶融状態にするのが好ましい。 Then, before the back mold 2 is sucked, the thermosetting synthetic resin material of the backboard material 4 ′ is melted so that the backboard material 4 ′ has air permeability, and the mold of the back mold 2 It is preferable to heat the mold itself so as to be adsorbed to the surface, or blow hot air from the vent holes 20 and 20 to bring the synthetic resin material into a molten state.
また、バックボード４を成形後、脱型する際に、前記通気孔２０、２０…より圧空ブローを行うことができるように構成されている。 Further, when the backboard 4 is molded and then removed from the mold, compressed air blow can be performed from the vent holes 20, 20.
なお、バックボード材４´の内面又は外面には合成樹脂フィルムをラミネートして、前記背面成形型２に真空成形による成形性を向上させるようにしてもよい。 In addition, a synthetic resin film may be laminated on the inner surface or the outer surface of the backboard material 4 ′ to improve the moldability of the back surface mold 2 by vacuum forming.
以上のパッド５を内部に装着した袋状の外被部材Ａは、背面成形型２上に載置してバックボード材４´を加熱して熱硬化合成樹脂材を溶融する。
次に、スチームなどで加熱されている表面成形型１を下降させて、表皮材３´を加熱してパッド５の前面に加圧する。
The bag-shaped jacket member A with the above pad 5 mounted therein is placed on the back mold 2 and the backboard material 4 'is heated to melt the thermosetting synthetic resin material.
Next, the surface molding die 1 heated by steam or the like is lowered, and the skin material 3 ′ is heated and pressed against the front surface of the pad 5.
それと同時、又は、表皮材３´をパッド５の前面に加圧して成形と同時に接着して表皮材３´を成形接着した後、背面成形型２でバックボード材４´を真空吸引して、背面成形型２に沿わせると共に加熱してバックボード材４´の熱硬化合成樹脂材を硬化させてバックボード４を成形する。 At the same time or after pressurizing the skin material 3 ′ on the front surface of the pad 5 and adhering it at the same time as molding, the skin material 3 ′ is molded and bonded, and then the back board material 4 ′ is vacuum-sucked with the back mold 2, The backboard 4 is molded by heating along the back mold 2 and curing the thermosetting synthetic resin material of the backboard material 4 ′.
然る後、一定の硬化時間経過後、表面成形型１を上昇させて、脱型することにより、図２に示すシートバックが製造される。 Thereafter, after a certain curing time elapses, the surface mold 1 is raised and removed to produce the seat back shown in FIG.
従って、表面成形型１と背面成形型２の上、下一対の型を使用してシートバックを製造できるのでシートバックの製造効率を向上し得る。 Therefore, since the seat back can be manufactured using the upper and lower pair of molds on the surface mold 1 and the back mold 2, the manufacturing efficiency of the seat back can be improved.
しかも、表面成形型１と背面成形型２を協働させて同時に、表皮とバックボードを成形することにより、より一層製造効率が良好となる。 In addition, manufacturing efficiency can be further improved by forming the skin and the backboard simultaneously with the surface mold 1 and the back mold 2 in cooperation.
