Description

【0001】
【発明の属する技術分野】
本発明は自動車用シートなどの車両用シートの合成樹脂製嵌合体、詳しくは、リクライニングデバイスなどを被包する合成樹脂製ガーニッシュ、ヘッドレスト、アームレストなどの略箱体状の合成樹脂製芯体に関する。
【0002】
【従来の技術】
従来の例えば、リクライニングデバイスからスライドレールのアッパーレールを被覆する樹脂製のガーニッシュには、アウターカバーとインナーカバーとから構成されているものがある。
以上のアウターカバーとインナーカバーは各々略コ字状に成形され、各々の内側を向かい合わせて嵌合することにより略箱体状になり、リクライニングデバイス等を被包する構造である。
【0003】
そして、前記アウターカバーとインナーカバーの各々の端縁には相互に係合する係合爪を複数設け、両係合爪を係合することにより、インナーカバーとアウターカバーとを一体に連結している。
【0004】
【発明が解決しようとする課題】
以上の係合爪でインナーカバーにアウターカバーを連結した構造の従来品は、インナーカバー、アウターカバーの外側からの負荷が加わると、各係合爪にその負荷が集中するため、各係合爪が変形し白化する虞れがある。
そのため、シートを長期使用すると、インナーカバーからアウターカバーが外れ易くなる不具合があった。
【0005】
そこで、本発明はインナーカバーからアウターカバーが外れる虞れがないようにすることを目的とする。
【0006】
【課題を解決するための手段】
以上の目的を達成するための本発明は、インナーカバーの端縁に沿って設けた嵌合凹部に、アウターカバーの端縁に沿って設けた嵌合凸部を相互に嵌合することにより形成する車両用シートの合成樹脂製嵌合体であって、前記インナーカバーの内面に、アウターカバーの内面方向に突出すると共に先端に係止爪を有する突片と、この突片の係止爪が係合する係止孔を有し、アウターカバーからインナーカバー方向に突出する係止体とを有する構成である。
【0007】
以上の構成により、インナーカバーとアウターカバーが各々の内部で突片と係止体とにより連結されているため、外側からの荷重が受け難く、突片が係止体から外れる虞れが少ない。
【0008】
また、前記アウターカバーの内面に設けた係止体はコ字状に形成し、インナーカバー方向の端縁を除く端縁をアウターカバーの内面に一体に設け、該係止体内に前記突片を挿入し、係止爪を係止体の係止孔に係止してなることにより、突片の係止体に対する係止状態が良好になり、更に、インナーカバーとアウターカバーとの連結状態が向上する。
【0009】
【発明の実施の形態】
以下、本発明の実施の一形態を図面に基づいて説明する。
図1は本発明に係る合成樹脂製嵌合体の一例としてガーニッシュ(C)を示し、このガーニッシュ(C)によってリクライニングデバイスからスライドレールのアッパーレールを被覆して、シートの外観品質を向上させている。
【0010】
このガーニッシュ(C)はインナーカバー(2)とアウターカバー(1)とから構成され、このインナーカバー(2)に対してアウターカバー(1)は一体に連結されている。
【0011】
なお、図1において、図中(3)はリクライニングデバイスのロック解除用レバー、(SB)はシートバック、(SC)はシートクッションを各々示す。
【0012】
アウターカバー(1)、インナーカバー(2)は、図2乃至図4に示すように構成されている。
即ち、アウターカバー(1)は起立状の主体(1B)の周囲に内方に折曲するフランジ(1A)を一体成形し、フランジ(1A)における全周の端縁には嵌合凹部(12)を延設し、その内面に複数の係止体(10)を設けている。
【0013】
この各係止体(10)は図4に示すようにコ字状でインナーカバー(2)側の端縁を除く全ての端縁が主体(1B)とフランジ(1A)に一体に固着され、係止孔(11)が上下のフランジ(1A)に向き合う面に開孔されている。
【0014】
一方、インナーカバー(2)はシートクッション(SC)側に設けて外部から視覚されるスライドレールのアッパーレール、リクライニングデバイスを被覆するように形成され、端縁に沿って前記アウターカバー(2)の嵌合凸部(12)が外側に嵌合される嵌合凹部(22)が全周に形成され、図3に示すように、嵌合凸部(12)が嵌合凹部(22)に嵌合するように形成されている。
【0015】
そして、インナーカバー(2)には、図4に示すように、前記係止体(10)に挿し込まれる突片(21)(21)が内面に設けてあり、この突片(21)の先端には係合体(10)の内側から係止孔(11)に係止する係止爪(21A)が一体成形されている。
【0016】
なお、インナーカバー(2)は起立状の本体(2B)と、この本体(2B)と一体のフランジ部(2A)とから構成され、前記嵌合凹部(22)はフランジ部(2A)の先端周囲に設けてある。
【0017】
以上のインナーカバー(2)に設けた係止爪(21A)付の突片(21)は、図3に示すように、アウターカバー(1)の係止体(10)に係止することにより、インナーカバー(2)とアウターカバー(1)が一体に連結され、前記ガーニッシュ(C)を構成する。
【0018】
このガーニッシュ(C)は、例えばアウターカバー(1)に外力がかかっても、その負荷をアウターカバー(1)の全周に設けた嵌合凸部(12)と、インナーカバー(2)の嵌合凹部(22)で受け、アウターカバー(1)とインナーカバー(2)の内部に設けた係止爪(21A)、係止体(10)に、前記負荷が作用しない。
そのため、係止爪(21A)が係止体(10)の係止孔(11)から外れる虞れがない。
【0019】
また、インナーカバー(2)の突片(21)がアウターカバー(1)方向に向けて突設されているため、突片(21)が撓み、係止爪(21A)の係止孔(11)に対する係止を容易に行うことができる。
【0020】
なお、図示するものは、ガーニッシュであるが、アームレスト、ヘッドレストなどの合成樹脂製箱体状の芯体(フレーム)の形成にも本発明は利用できる。
【0021】
また、図示するものは、アウターカバー(1)側に係止体(10)、インナーカバー(2)側に係止爪(21A)の突片(21)を設けているが、これを逆にしても良い。
【0022】
【発明の効果】
本請求項1の発明によれば、インナーカバーとアウターカバーの内部で、係止爪を係止体の係止孔に係止しているため、外方からの衝撃等によって、アウターカバーがインナーカバーから外れることがない。
【0023】
本請求項2の発明によれば、係止体がアウターカバーに一体に設けているため、この係止体の係止孔に係止する係止爪の係止状態が良好になり、更に、アウターカバーのインナーカバーに対する取付性が良好となる。
