Description
本発明は、自動車等のシート上部に装備されるヘッドレストと、その製造方法に関するものである。 The present invention relates to a headrest mounted on an upper part of a seat of an automobile or the like and a manufacturing method thereof.
自動車等のシートの上部には、ヘッドレストが装備されている。このヘッドレストは、例えば特許文献１に示すように、表皮材を袋状に縫合し、その内部にステーを挿入した上で、表皮材内に発泡性樹脂を注入して発泡成形を行うことにより、一体形成されることが通常である。なお、前記縫合箇所には、発泡性樹脂の含浸を防止するためのフィルムテープが貼付される。しかしながら、フィルムテープを貼付した場合でも、発泡成形の際に、発泡性樹脂が縫合箇所からわずかに漏れてしまい、製造の最終工程で不良品が発生することとなり、製造歩留りが低下してしまう問題があった。 A headrest is mounted on the upper part of the seat of an automobile or the like. For example, as shown in Patent Document 1, the headrest is stitched into a bag shape, and after inserting a stay therein, foaming resin is injected into the skin material to perform foam molding. Usually, they are integrally formed. A film tape for preventing impregnation of the foamable resin is affixed to the stitched portion. However, even when a film tape is affixed, the foamable resin slightly leaks from the stitched part during foam molding, resulting in a defective product in the final manufacturing process and a decrease in manufacturing yield. was there.
また、近年はエコカー等に代表されるように、地球環境に優しい自動車の開発が進んでおり、省エネルギーで走行するためにも、自動車を軽量化することは重要な要素となる。そのような中で、ヘッドレストを軽量化するというに点ついては、検討がなされることは少なかった。 In recent years, as represented by eco-cars and the like, development of automobiles that are friendly to the global environment has been progressing, and it is an important factor to reduce the weight of automobiles in order to travel with energy saving. Under such circumstances, there have been few studies on reducing the weight of the headrest.

以上のように構成したヘッドレスト１は、芯材２にステー６を固定して完成品となるため、従来のように発泡成形することなく製造可能であることから、発泡性樹脂が漏れることがなく、高い製造歩留りを有するものとなる。また、発泡性樹脂を使用しないため、従来と比較して軽量化を実現することができる。さらに、従来は３枚の表皮材を袋状に縫合することが通常であったが、本実施形態のような構成することで、表皮材同士を袋状に縫合する必要がなくなるため、低コストで製造可能となる。加えて、縫合箇所にフィルムテープを貼付する必要もなくなり、より低コストで製造可能となる。また、芯材２を樹脂製とすることで、充分な強度も担保しつつ、軽量化を実現することが可能となる。 Since the headrest 1 configured as described above is a finished product by fixing the stay 6 to the core material 2, it can be manufactured without foaming as in the prior art, so that the foamable resin does not leak. , Having a high production yield. Moreover, since no foamable resin is used, the weight can be reduced as compared with the conventional case. In addition, it has been usual to sew three skin materials into a bag shape, but it is not necessary to sew the skin materials into a bag shape by configuring as in this embodiment, so that the cost is low. Can be manufactured. In addition, it is not necessary to affix a film tape to the stitched portion, and it can be manufactured at a lower cost. Further, by making the core material 2 made of resin, it is possible to reduce the weight while ensuring sufficient strength.
上記ヘッドレスト１の組付けについて、以下に説明する。
平板状に形成された表皮材３を芯材２の外周に巻付けた上で、両端の開口部４側の表皮材３の外縁部を、芯材２に対してタッカーにより固定する。そして、図３のように、表皮材２の端部２ａを挿通孔９に挿入する。これにより、表皮材３が芯材２に固定される。次いで、ステー６の基部８側を挿通孔９に挿入し、さらに押し込んで、芯材２の内側に設けられた第１係止部材１０に基部８を固定することで、図３に示す状態となる。そして、両端の開口部４にマチ部材５を取付けることで、図１に示す完成品となる。このように、基部８は第１係止部材１０にワンタッチで固定され、ステー６が芯材２に固定されることとなる。また、マチ部材５の内側には、マチ部材５を脚部７に固定する第２係止部材１１が設けられていることから、この第２係止部材１１を脚部７にワンタッチで係止させることにより、マチ部材５が脚部７に固定されることとなる。このように、各部材を組付けることでヘッドレスト１を製造することが可能であるため、非常に高い製造歩留りとなる。
The assembly of the headrest 1 will be described below.
After the skin material 3 formed in a flat plate shape is wound around the outer periphery of the core material 2, the outer edge portions of the skin material 3 on the opening 4 side at both ends are fixed to the core material 2 with a tacker. Then, the end 2a of the skin material 2 is inserted into the insertion hole 9 as shown in FIG. Thereby, the skin material 3 is fixed to the core material 2. Next, by inserting the base 8 side of the stay 6 into the insertion hole 9 and further pushing it in, and fixing the base 8 to the first locking member 10 provided inside the core member 2, the state shown in FIG. Become. And the finished product shown in FIG. 1 is obtained by attaching the gusset member 5 to the openings 4 at both ends. In this way, the base 8 is fixed to the first locking member 10 with one touch, and the stay 6 is fixed to the core member 2. Moreover, since the 2nd latching member 11 which fixes the gusset member 5 to the leg part 7 is provided inside the gusset member 5, this 2nd latching member 11 is latched to the leg part 7 by one touch. By doing so, the gusset member 5 is fixed to the leg portion 7. Thus, since the headrest 1 can be manufactured by assembling each member, the manufacturing yield is extremely high.
芯材２には、図３のように一方の開口部４から他方の開口部４にかけて、その長手方向に、一定間隔で１０本の長孔状のスリット１２が形成されている。これにより、芯材２に柔軟性を持たせることができ、人がヘッドレスト１に頭部を載せた際に、快適に使用可能となる。また、スリットの数はこれに限定されず、その数を適切に変更することで、最適な柔軟性を有する芯材２とすることもできる。なお、スリット１２を形成せずに、芯材２の素材を変更することにより、最適な柔軟性を有するものとしても良いことは言うまでもない。 As shown in FIG. 3, ten long-hole-shaped slits 12 are formed in the core member 2 at regular intervals from one opening 4 to the other opening 4 in the longitudinal direction. Thereby, flexibility can be given to the core material 2, and when a person puts the head on the headrest 1, it can be used comfortably. Further, the number of slits is not limited to this, and the core material 2 having optimum flexibility can be obtained by appropriately changing the number of slits. In addition, it cannot be overemphasized that it is good also as what has the optimal softness | flexibility by changing the raw material of the core material 2, without forming the slit 12. FIG.
本実施形態においては、芯材２は樹脂製としたが、例えば充分な強度を備えた紙材により構成しても良く、その場合においても、長手方向に長孔状のスリット１２を形成することが望ましい。これにより、芯材２を樹脂製とした場合と同様に、柔軟性を備えた上で、充分な強度も担保しつつ、軽量化を実現することが可能となる。 In the present embodiment, the core material 2 is made of resin. However, the core material 2 may be made of, for example, a paper material having sufficient strength, and in that case, the long hole-like slit 12 is formed in the longitudinal direction. Is desirable. As a result, as in the case where the core material 2 is made of resin, it is possible to achieve weight reduction while ensuring sufficient strength while providing flexibility.
また、本実施形態では、ステー６を金属製のものとしたが、このステー６を樹脂製とすることにより、さらに軽量化したヘッドレスト１としても良い。 In the present embodiment, the stay 6 is made of metal, but the headrest 1 may be made lighter by making the stay 6 made of resin.
