Description
あるいは、前記スリットは、前記エアバッグの展開時に前後方向に延びる水平スリット領域と、当該水平スリット領域の後端部から上下方向に延びる垂直スリット領域とを含み、車幅方向から見たときに横向きのT字状をなすように構成することができる。
また、各実施例においては、同一又は対応する構成要素については同一の参照符号を付し、重複した説明は省略する。
図8は、本発明の第3実施例に係るエアバッグ装置の作動状態(エアバッグ14の展開状態)を示す説明図であり、正面から見た様子を示す。本実施例においては、第1及び第2実施例に採用されるスリット50(50a,50b)をエアバッグ14の左右両側に設けている。
図9は、本発明の第4実施例に係るエアバッグ装置のインフレータの配置を説明するための説明図であり、車両用シートを背面側から見た様子を模式的に示す。本実施例においては、シートバック2の背面にインフレータ64を配置する。インフレータ64としては、シリンダータイプに替えてディスクタイプのインフレータを採用することができる。インフレータ64から放出される膨張ガスは、パイプ等のガスガイド(流路)66a,66bを通って、左右のサイドチャンバ16a,16bに供給されるようになっている。
Claims (15)
- 座面を形成するシートクッションと背もたれを形成するシートバックとを有する車両用シートに装備されるエアバッグ装置であって、
膨張ガスを発生するインフレータと、
前記インフレータから放出される膨張ガスによって展開するエアバッグとを備え、
前記エアバッグは、前記シートバックの側部から前方に向かって展開し、主に乗員の腰部から肩部を保護する左右一対のサイドチャンバと、前記サイドチャンバと連続して設けられ、当該サイドチャンバの上方で前方に向かって展開し、主に乗員の頚部及び頭部を保護する上部チャンバとを含み、
前記シートバックの左右側部において、肩部付近でシートベルトが横切る側を第1の側とし、当該第1の側と左右反対側を第2の側としたときに、前記エアバッグの前記第1の側に前記シートベルトが収まる凹部が形成されており、
前記凹部は、前記エアバッグの展開時に前後方向に延びるスリットであり、
前記エアバッグの展開初期の段階で前記シートベルトが当該スリットの後方に相対的に移動することによって前記上部チャンバへのガスの流入が遮断され又は制限されて前記凹部の展開が規制され、前記エアバッグの内圧の上昇に伴って当該凹部が開放されて、前記膨張ガスが前記第1の側のサイドチャンバから前記上部チャンバに流れ込むように構成されていることを特徴とするエアバッグ装置。 - 前記スリットは、前記エアバッグの展開時に前後方向に延びる水平スリット領域と、当該水平スリット領域の後端部から上方向に延びる垂直スリット領域とを含み、車幅方向から見たときに横向きのL字状をなすように形成されていることを特徴とする請求項1に記載のエアバッグ装置。
- 前記スリットは、前記エアバッグの展開時に前後方向に延びる水平スリット領域と、当該水平スリット領域の後端部から上下方向に延びる垂直スリット領域とを含み、車幅方向から見たときに横向きのT字状をなすように形成されていることを特徴とする請求項1に記載のエアバッグ装置。
- 前記水平スリット領域は、前端部から後方に向かって狭くなるテーパ状に成形されていることを特徴とする請求項2又は3に記載のエアバッグ装置。
- 前記一対のサイドチャンバの上部が前記上部チャンバによって連結されていることを特徴とする請求項1乃至4の何れか1項に記載のエアバッグ装置。
- 前記上部チャンバは、前記第1の側のサイドチャンバと流体的に連通した第1領域と、前記第2の側のサイドチャンバと流体的に連通した第2領域とを含み、これら第1及び第2領域同士は流体的に分離されていることを特徴とする請求項5に記載のエアバッグ装置。
- 前記インフレータは、前記一対のサイドチャンバ内に収容された一対のインフレータであることを特徴とする請求項6に記載のエアバッグ装置。
- 前記一対のインフレータから放出される膨張ガスは、前記一対のサイドチャンバの各々から前記上部チャンバの前記第1及び第2領域に流れ込むように構成されていることを特徴とする請求項7に記載のエアバッグ装置。
- 前記上部チャンバは、前記第1の側のサイドチャンバと流体的に連通した第1領域と、前記第2の側のサイドチャンバと流体的に連通した第2領域とを含み、これら第1及び第2領域同士は流体的に連通していることを特徴とする請求項5に記載のエアバッグ装置。
- 前記インフレータは、前記第1の側の前記サイドチャンバ内に収容されることを特徴とする請求項9に記載のエアバッグ装置。
- 前記インフレータから放出される膨張ガスは、前記第1の側のサイドチャンバから、前記上部チャンバの前記第1領域及び第2領域を通って、前記第2の側のサイドチャンバに流れ込むように構成されていることを特徴とする請求項10に記載のエアバッグ装置。
- 前記凹部は、前記第1の側に加えて前記第2の側にも形成されることを特徴とする請求項1乃至11の何れか1項に記載のエアバッグ装置。
- 前記インフレータは、前記シートバックの背面に収容される背面インフレータを含むことを特徴とする請求項6又は9に記載のエアバッグ装置。
- 前記インフレータから放出される膨張ガスは、少なくとも前記第1の側のサイドチャンバ又は、前記第2の側のサイドチャンバのいずれか一方に流れ込むように構成されていることを特徴とする請求項13に記載のエアバッグ装置。
- 請求項1乃至14の何れか1項に記載のエアバッグ装置を備えた車両用シート。
