【０００６】
【実施例】
本発明の穴開きヘッドレストの表皮部材縫着方法を実施しうる例をヘッドレストの図面により説明すると、１は中央に穴２のある穴開きヘッドレストであり、図示は省略するがウレタン等のクッション材の表面を表皮部材３により包囲する。
表皮部材３は、中央の穴２を基準に上前側部材４および上後側部材５の上側部材６と、左前側部部材７および左後側部部材８の左側部材９と、右前側部部材１０および右後側部部材１１の右側部材１２と、下側部材１３と、下側部材１３の下縁に取付ける前側下面部材１４および後側下面部材１５により構成し、各部材は、夫々表面１６と裏面１７とを有し、理解を容易にするため、裏面は点模様を付して図示することがある（なお、点模様は理解を容易にするためのものであり、各図において整合しないこともあるが、これによって構成が限定されない）。
【０００７】
しかして、表皮部材３は、まず、上側部材６に左側部材９と右側部材１２を逢着する。
縫製順序は任意であるが、上側部材６の上前側部材４と上後側部材５の上縁２０を重合させて逢着２１し、左側部材９の左前側部部材７と左後側部部材８の外縁２２を重合させて逢着２３し、右側部材１２の右前側部部材１０と右後側側部材１１の外縁２４を重合させて逢着２５し、この上前側部材４と上後側部材５の左縁２６に左前側部部材７と左後側部部材８の上縁２７を重合させて逢着２８し、上前側部材４と上後側部材５の右縁２９に右後側部部材１１と右側部材１２の上縁３０を重合させて逢着３１し、上側部材６と左側部材９と右側部材１２は夫々の穴２側内周縁を開放したままの一枚布地状態に縫製する。
【０００８】
この状態で、次に、上側部材６の上前側部材４および上後側部材５と、左側部材９の左前側部部材７および左後側部部材８と、右側部材１２の右後側部部材１１および右側部材１２の夫々の縫着した合せ目３４の両側に装飾用のダブルステッチと呼ばれるダブルステッチ縫い目３５等の装飾用縫い目３６を施す。
ダブルステッチ等の装飾用縫い目３６は、表皮部材３に糸を上下に貫通させることで可能になる縫製技術であるから、重合状態の布地では縫製できず、上側部材６と左側部材９と右側部材１２とを一枚布地状態に縫製することで、実現できる。
【０００９】
しかして、一枚布地状態に縫製した上側部材６と左側部材９と右側部材１２とは裏返した状態で穴側内周縁３７を重合させて縫着３８する。このように連結した一体状態に縫製した上側部材６と左側部材９と右側部材１２により逆Ｕ型部材４０を構成し、逆Ｕ型部材４０は左右両側下部を開口した逆Ｕ型形状に縫製され、この逆Ｕ型部材４０は左右両側下部の何れかの開口部より表裏反転させる。
しかして、下側部材１３の前縁４１には前側下面部材１４の前縁４２を重合させて縫着４３し、下側部材１３の後縁４４には後側下面部材１５の後縁４５を重合させて縫着４６し、前側下面部材１４の後縁４７と後側下面部材１５の前縁４８とは逢着せずに開口部４９を形成する。
【００１０】
次に、逆Ｕ型部材４０は前記前側下面部材１４と後側下面部材１５を逢着した下側部材１３と縫製する。
逆Ｕ型部材４０と下側部材１３との縫製は、まず、下側部材１３全体を裏返し、逆Ｕ型部材４０の左下縁５０を下側部材１３の開口部４９より挿入して下側部材１３の左縁５１と重合させ、この状態で左下縁５０と左縁５１とを縫着５２する。
同様に、逆Ｕ型部材４０の右下縁５３を下側部材１３の開口部４９より挿入して下側部材１３の右縁５４と重合させ、この状態で右下縁５３と右縁５４とを縫着５５する。
【００１１】
次に、逆Ｕ型部材４０の左下縁５０と右下縁５３を開口部４９より引き抜き、下側部材１３全体を表返しすると、縫製が完了する。
しかして、縫製された表皮部材３にステー５６を装着し、この状態の表皮部材３を金型にセットし、クッション材を発泡注入すると、穴開きヘッドレスト１が完成する。
【００１２】
この場合、ステー５６は、前側下面部材１４の透孔５７のうち左右側の透孔５７に夫々挿入し、中央の透孔５７よりクッション材を発泡注入すると、ステー５６のセットおよびクッション材の発泡注入が容易になって、好適である。
なお、各図において、実際の縫着部分が表面から見えない内側に存在していることがあるが、位置関係を表現するため、ヘッドレスト１の外側に縫着部分を示す符号を付している。したがって、この符号のみをもって、縫着部分は限定されない。
【００１３】
【効果】
本発明は、中央の穴２の上方に位置する上前側部材４および上後側部材５の上側部材６と、穴２の左側に位置する左前側部部材７および左後側部部材８の左側部材９と、穴２の右側に位置する右前側部部材１０および右後側部部材１１の右側部材１２と、穴２の下方に位置する下側部材１３と、下側部材１３の下縁に取付ける前側下面部材１４および後側下面部材１５により表皮部材３を構成し、前記表皮部材３は、上側部材６と左側部材９と右側部材１２とを夫々の穴２側内周縁を開放したままの一枚布地状態に縫製し、次に、一枚布地状態に縫製した上側部材６と左側部材９と右側部材１２とは裏返した状態で穴側内周縁３７を重合させて縫着し縫着後表裏反転させて逆Ｕ型部材４０に構成し、次に、筒状に縫製して全体を裏返した下側部材１３の開口部４９より逆Ｕ型部材４０の左下縁５０および右下縁５３を夫々挿入して下側部材１３の左縁５１および右縁５４と夫々重合させて縫着し、縫着後、開口部４９より逆Ｕ型部材４０の左下縁５０および右下縁５３を引き出して下側部材１３の表裏反転させる穴開きヘッドレストの表皮部材縫着方法、および、中央の穴２の上方に位置する上前側部材４および上後側部材５の上側部材６と、穴２の左側に位置する左前側部部材７および左後側部部材８の左側部材９と、穴２の右側に位置する右前側部部材１０および右後側部部材１１の右側部材１２と、穴２の下方に位置する下側部材１３と、下側部材１３の下縁に取付ける前側下面部材１４および後側下面部材１５により表皮部材３を構成し、前記表皮部材３は、上側部材６と左側部材９と右側部材１２とを夫々の穴２側内周縁を開放したままの一枚布地状態に縫製し、次に、上側部材６と左側部材９と右側部材１２の略前後中間の長さ方向にダブルステッチ縫い目３５を施し、次に、一枚布地状態に縫製した上側部材６と左側部材９と右側部材１２とは裏返した状態で穴側内周縁３７を重合させて縫着し縫着後表裏反転させて逆Ｕ型部材４０に構成し、次に、筒状に縫製して全体を裏返した下側部材１３の開口部４９より逆Ｕ型部材４０の左下縁５０および右下縁５３を夫々挿入して下側部材１３の左縁５１および右縁５４と夫々重合させて縫着し、縫着後、開口部４９より逆Ｕ型部材４０の左下縁５０および右下縁５３を引き出して下側部材１３の表裏反転させる穴開きヘッドレストの表皮部材縫着方法としたものであるから、一枚布地状態に縫製した上側部材６と左側部材９と右側部材１２とに装飾用縫い目３６を容易に施すことができ、外観デザインの制約も少なく自由度を向上させることができる。

[0006]
【Example】
An example in which the skin member sewing method for a perforated headrest according to the present invention can be implemented will be described with reference to the drawings of the headrest. 1 is a perforated headrest having a hole 2 in the center, and although not shown, a cushioning material such as urethane is used. The surface is surrounded by the skin member 3.
The skin member 3 includes an upper member 6 of the upper front member 4 and the upper rear member 5, the left member 9 of the left front member 7 and the left rear member 8, and the right front member with respect to the central hole 2. 10 and the right side member 12 of the right rear side member 11, the lower side member 13, and the front lower surface member 14 and the rear lower surface member 15 attached to the lower edge of the lower member 13. In order to facilitate understanding, the back surface may be illustrated with a dot pattern (note that the dot pattern is for ease of understanding and does not match in each figure) In some cases, this does not limit the configuration).
[0007]
Thus, the skin member 3 first attaches the left member 9 and the right member 12 to the upper member 6.
Although the sewing order is arbitrary, the upper front member 4 of the upper member 6 and the upper edge 20 of the upper rear member 5 are overlapped and attached, and the left front member 7 and the left rear member 8 of the left member 9 are bonded. The outer edge 22 of the right member 12 is superposed and attached 23, and the right front side member 10 of the right member 12 and the outer edge 24 of the right rear member 11 are superposed and attached 25, and the upper front member 4 and the upper rear member 5 The upper edge 27 of the left front side member 7 and the left rear side member 8 are overlapped and attached to the left edge 26, and the right rear side member 11 is attached to the right edge 29 of the upper front member 4 and the upper rear member 5.

The openings 46 are overlapped and sewn 46 so that the rear edge 47 of the front lower surface member 14 and the front edge 48 of the rear lower surface member 15 are not attached to each other, and an opening 49 is formed.
[0010]
Next, the inverted U-shaped member 40 is sewn with the lower member 13 with the front lower surface member 14 and the rear lower surface member 15 attached thereto.
To sew the inverted U-shaped member 40 and the lower member 13, first, the entire lower member 13 is turned over, and the lower left edge 50 of the inverted U-shaped member 40 is inserted through the opening 49 of the lower member 13. 13 and the left lower edge 50 and the left edge 51 are sewn 52 in this state.
Similarly, the right lower edge 53 of the inverted U-shaped member 40 is inserted from the opening 49 of the lower member 13 and overlapped with the right edge 54 of the lower member 13. In this state, the right lower edge 53 and the right edge 54 Is sewn 55.
[0011]
Next, when the left lower edge 50 and the right lower edge 53 of the inverted U-shaped member 40 are pulled out from the opening 49 and the entire lower member 13 is turned over, the sewing is completed.
When the stay 56 is attached to the sewn skin member 3, the skin member 3 in this state is set in a mold, and the cushion material is foamed and injected, the perforated headrest 1 is completed.
[0012]
In this case, the stay 56 is inserted into the left and right side through holes 57 of the front side lower surface member 14, and the cushion material is foamed and injected from the central through hole 57. The injection becomes easy and is preferable.
In each figure, the actual sewing portion may be present on the inner side where it cannot be seen from the surface, but in order to express the positional relationship, a symbol indicating the sewing portion is attached to the outer side of the headrest 1. . Therefore, the sewn portion is not limited only by this code.
