Description

【0001】
【発明の属する技術分野】
本発明は、自動車用シート(座席)のシートバック(背凭部)構造に関する。
【0002】
【従来の技術】
従来の自動車用シートのシートバックにはシートバックの下部左右両外側面を内方に向けて凹窪状に形成し、この凹窪状に形成した部分に、リクライニング装置、前倒れ装置を取付けたものがある。
【0003】
従って、シートバックの下部左右外側面に設けたリクライニング装置などの外面が露出している。
【0004】
【発明が解決しようとする課題】
そのため、リクライニング装置などが露出するため、リクライニング装置などを樹脂製カバーで被覆している。しかし、シートバックの下部における左右方向の幅が上部に対して狭いため、シートバック全体の外観品質が損なわれるなどの不具合があった。
【0005】
そこで、本発明は斯様に左右両外側面にリクライニング装置などの傾動装置を備え、このリクライニング装置などを有する部分の左右の幅が上部の幅に対して狭く形成してなるシートバックにおいて、外観品質を向上させ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に係るシートバックは、下部の左右方向 の幅が上部の左右方向の幅に対して狭く形成した本体と、この本体内に上部の 幅が下部の幅に対して広い枠状のフレームを設けてなるシートバックにおいて、 前記本体の下部左右両側面に、前倒れ装置又はリクライニング装置からなる傾 動装置を設け、この両傾動装置の外側に、本体の一部を前記本体の下部とで傾 動装置を左右に挟むように延設する傾動装被覆用の被覆部を設け、該被覆 部は本体の発泡体製パッドと一体のサイドパッドと、このサイドパッドを被覆 する袋状の表皮とからなることを特徴とする構成である。
【0007】
以上の構成により、左右に設けた傾動装置は、本体と一体の被覆部によって被覆され、左右の被覆部によってシートバックの下部左右の間の幅が上部と同一となり、シートバックの外観品質を向上させることができる。
【0008】
【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乃至図3は、本発明に係るシートバックSBを備えた自動車用シートのリャシートを示し、図1はシートの使用可能状態、図3はシートバックSBをシートクッションSC上に前倒した状態を各々示す。以上のシートバックSBはシートクッションSCに傾動装置Rによって矢印方向である前倒方向に前倒れ又は前傾可能に連結されている。
【0009】
シートバックSBは、図1に示すように、本体1下部の左右方向の幅W1が 上部の左右方向の幅W2に対して狭く形成されている。そして、この本体1内 には本体1の外周に沿うように、上部の幅が下部の幅に対して広い枠状のフレ ーム12が設けてある。また、その本体1の下部左右には、前倒装置又はリク ライニング装置などの傾動装置R、Rが装着されている。この傾動装置R、R は図示するが如く、本体1の下部と後述する傾動装置R、R被覆用の被覆部2、 2とによって左右に挟まれる。
【0010】
この各傾動装置R、Rの外面は、本体1と一体成形した被覆部2、2によって被覆されている。
本体1は従来のシートバックと同様にフレーム12などの支持部材と、モールド加工した発泡体製パッド10と、このパッド10を被包するトリムカバー11、11A、11Bとから構成されている。
【0011】
前記被覆部2は、本体1のパッド10と一体にモールド成形したサイドパッド20と、このサイドパッド20を被覆する袋状の表皮21とから構成されている。
【0012】
この表皮21は、前記本体1のトリムカバー11、11Aに一体に形成され、本体1のトリムカバー11と同様に前面部21Aが接着剤21Bによってサイドパッド20の前面20Aに接着されている。
【0013】
図中11は本体1のトリムカバーの身頃部、11Aは同まち部、11Bは後まち部で、その端末にはファスナーの雄体11B′が縫着され、本体1の背裏を構成する後身頃部11Cに一体に連結されている。図中R1は傾動装置Rのロック解除用操作レバーを示す。
【0014】
以上のサイドパッド20は図4に示すように本体1のパッド10と一体に成形され、パッド10とサイドパッド20の各々の着座面10A、20Aに接着剤を塗布する。そして、パッド10の着座面10Aを本体1のトリムカバーの身頃部11内面に、また、サイドパッド20を被覆部2の袋状の表皮21内に挿入し、パッド10、サイドパッド20を身頃部11、表皮21の着座部21Aに加圧して接着する。次に、まち部11A、後まち部11Bをパッド10に当てた後、前記後身頃部11Cを取付けると、図1、図3に示すシートバックSBが組立てられる。
【0015】
【発明の効果】
本発明によれば、シートバックの下部左右に有する傾動装置が本体と一体の被覆部によって被覆されるため、シートバックの外観品質が向上する。
【0016】
しかも、この被覆部により、シートバックの上下部における左右方向の幅を同一に形成できるため、更にシートバックの外観品質を向上させることができる。
【0017】
更に、表皮はあらかじめ袋状に縫製され、接ぎ合わせのための縫い代等が外部 に露出することがないため、更に、シートバックの外観品質を向上させることが できる。
