Description
【0001】
【産業上の利用分野】
本発明は車両用シート(座席)におけるシートバック(背凭部)のトリムカバーによる被覆構造に関する。
【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、図2に示すような構造のものがある。
図2において、図中(SB)はシートバック、(1)はトリムカバーのシートバック(SB)の背裏側を構成する背裏部、(2)は同シートバック(SB)の前面側を構成する前面部を各々示し、背裏部(1)の下端には縫糸(30)によって舌状の装飾片(A′)が設けてある。図中(SC)はシートクッションを示す。
【0003】
以上の装飾片(A′)は、図3に示すように装着され、装飾片(A′)は背裏部(1)に加わるF1方向の力によって外方に傾斜状に跳ね上がっている。
【0004】
この装飾片(A′)は、袋状に縫製したトリムカバーの開口部に設けてあり、このトリムカバー(1)(2)はその開口部を下向きにしてシートバックを構成するフレーム(6)及びこのフレーム(6)に支持される発泡体製のクッション体(7)を被覆し、且つ背裏部(1)側の開口部の一端部(10A)に内側に折り返す折返部(10B)を延設し、この折返部(10B)と前記一端部との間に樹脂プレート(11)を上下方向に向けて介在させると共に、前記折返部(10B)側に吊り部材(12)を一体に縫着し、この吊り部材(12)を前面部(2)側の開口部の他端部(20)に結着することにより、開口部を閉口している。
【0005】
以上の吊り部材(12)は、布地を折り返して袋状に形成し、その内部に芯材(12A)を挿通したものであり、この吊り部材(12)は前記他端部(20)にホッグリング(5)によって一体に結着している。
また、他端部(20)は折り返されて内部に芯材(20A)が挿入されている。
【0006】
以上の他端部(20)と吊り部材(12)との結着により、吊り部材(12)にはF2方向の引張力が作用する。
【0007】
そして、吊り部材(12)は折返部(10B)に一体に縫糸(40)によって縫着され、樹脂プレート(11)は前記一端部(10A)と折返部(10B)と吊り部材(12)と共に前記縫糸(30)によって縫着されている。
【0008】
【発明が解決しようとする課題】
従って、前述の如く、以上の装飾片(A′)は、前面部(2)からの引張力(F2)と、背裏部(1)の張力(F1)とが作用するが、縫糸(30)を基点に跳ね上がる。
【0009】
また、前面部(2)と吊り部材(12)との結着個所がシートバック(SB)の背裏方向から視覚される。
【0010】
そのため、シートバック(SB)の外観品質が損なわれる不具合があった。
そこで、本発明は斯様な従来品の不具合を除去することを目的とする。
【0011】
【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、 前記装飾片を構成する樹脂プレートの上部を、縫糸Aにより前記一端部、折返部、吊り部材の基端部と共に一体に縫着し、この縫糸Aでの縫着個所に対する下方位置において、樹脂プレートを、前記一端部を除く折返部、吊り部材に対し縫糸Bにより一体に縫着してなることを特徴とする。
【0012】
以上の構成により、トリムカバーの前面部からの引張力が下部の縫着個所に、トリムカバーの背裏部からの張力が上部の縫着個所に各々作用し、樹脂プレートから構成される装飾片が跳ね上がることなく垂直状になる。
【0013】
【発明の実施の形態】
以下、本発明の実施の一形態を図1に基づいて説明する。
図1において、図3と同一符号は同一部材を示し、その説明を省略する。
【0014】
装飾片(A)は、シートバック(SB)の背裏面に沿って下方に垂設されており、この装飾片(A)は上部の縫糸A(3)と、その下方の縫糸B(4)によって跳ね上げることがなく形成されている。
【0015】
縫糸A(3)はトリムカバーの背裏部(1)における開口部の一端部(10A)と、樹脂プレート(11)の上部と,折返部(10B),吊り部材(12)の基端部とを一体に縫着している。
【0016】
また、縫糸B(4)は縫糸A(3)に対して下方位置の樹脂プレート(11)と,前記一端部(10A)を除く折返部(10B),吊り部材(12)の先端側とを一体に縫着している。なお、この縫糸B(4)によるミシン縫いの後、縫糸A(3)によるミシン縫いを行う。
【0017】
即ち、 前記装飾片(A)を構成する樹脂プレート(11)の上部を、縫糸A(3)により前記一端部(10A)、折返部(10B)、吊り部材(12)の基端部と共に一体に縫着し、この縫糸A(3)での縫着個所に対する下方位置において、樹脂プレート(11)を、前記一端部(10A)を除く折返部(10B)(10B)、吊り部材(12)に対し縫糸B(4)により一体に縫着している。
【0018】
以上の装飾片(A)は、図2に示す従来品の如く、シートバック(SB)の背裏側における下端部に沿って形成されている。従って、樹脂プレート(11)は上下幅が狭い長尺状で保形性を有する合成樹脂製のプレートを使用している。
【0019】
トリムカバーの背裏部(1)には、前記従来品と同様にF1方向の張力が、また、吊り部材(12)には前面部(2)からのF2方向の引張力が各々作用する。
【0020】
しかし、縫糸A(3)、縫糸B(4)が前述の如く、樹脂プレート(11)を縫着しているため、装飾片(A)を構成する樹脂プレートがトリムカバーの背面部(1)の延長方向に保持される。
【0021】
【発明の効果】
本発明によれば、従来と同様に二ヶ所をミシン縫いすることにより、シートバックの背裏側における下端部に設けた装飾片の跳ね上がりを完全に防止できる。
【0022】
また、装飾片によって袋状のトリムカバーの開口部を閉口する吊り部材と前面側の他端部との結着個所を陰蔽できる。
【0023】
そのため、従来に対してミシン縫い個所を増すことなくシートバックの外観品質を向上させることができる。
