Description
まず、第1実施形態に係るエアバッグ装置30について説明する。図1、図2に示されるように、車両用シート10は、乗員Pが着座する(乗員Pの臀部及び大腿部を支持する)シートクッション12と、乗員Pの背部を支持するシートバック14と、乗員Pの頭部Phを支持するヘッドレスト16と、を有している。
なお、図4に示されるように、テザー38は、平面視略「Y」字状に形成されたテザー39とされてもよい。すなわち、テザー39は、一端部39Aが先端チャンバ36の上端部における先端部(後端部)に縫製によって取り付けられ、前後方向に離隔する前側他端部39Bと後側他端部39Cとがそれぞれ前後チャンバ34の上端部における中途部に縫製によって取り付けられる形状とされてもよい。
次に、第2実施形態に係るエアバッグ装置30について説明する。なお、上記第1実施形態と同等の部位には同じ符号を付して詳細な説明(共通する作用も含む)は適宜省略する。
次に、第3実施形態に係るエアバッグ装置30について説明する。なお、上記第2実施形態と同等の部位には同じ符号を付して詳細な説明(共通する作用も含む)は適宜省略する。
最後に、第4実施形態に係るエアバッグ装置30について説明する。なお、上記第1実施形態と同等の部位には同じ符号を付して詳細な説明(共通する作用も含む)は適宜省略する。

Claims (7)
- 車両の衝突が検出又は予知されることによって作動したインフレータから噴出されたガスにより、乗員の頭部の一側方を通ってシート前方側へ展開し、前記乗員の頭部の一側方に配置される前後チャンバと、該前後チャンバのシート前方側端部からシート幅方向内側へ展開し、前記乗員の顔のシート前方側に配置される左右チャンバと、該左右チャンバのシート幅方向内側端部からシート後方側へ展開し、前記乗員の頭部の他側方に配置される先端チャンバと、を有するとともに、前記前後チャンバと前記先端チャンバとを連結するテザーを有する外側エアバッグ部と、
前記外側エアバッグ部から流入された前記ガスにより、前記前後チャンバと前記左右チャンバと前記先端チャンバとの間に展開して配置されるとともに、乗員の頭部を拘束する頭部拘束面を有する内側エアバッグ部と、
を含んで構成されたエアバッグ本体を備えたシート搭載型エアバッグ装置。 - 平面視で、前記内側エアバッグ部の頭部拘束面における前記先端チャンバ側に、前記前後チャンバ側よりもシート後方側へ向かって突出する突出部が形成されている請求項1に記載のシート搭載型エアバッグ装置。
- 平面視で、前記内側エアバッグ部の前記突出部を除くシート前後方向の長さが、シート幅方向の長さよりも長くされている請求項2に記載のシート搭載型エアバッグ装置。
- 平面視で、前記内側エアバッグ部は、シート幅方向に所定の厚みを有する略楕円形状に形成されるとともに、そのシート後方側端部が前記前後チャンバから離れるように、シート前後方向に対して斜めに配置されている請求項1に記載のシート搭載型エアバッグ装置。
- 前記内側エアバッグ部には、前記ガスを排出するベントホールが形成されており、
前記ベントホールの開口面積が、前記外側エアバッグ部から前記内側エアバッグ部へ前記ガスを流入させるための流入口の開口面積よりも大きくされている請求項1~請求項4の何れか1項に記載のシート搭載型エアバッグ装置。 - 前記外側エアバッグ部から前記内側エアバッグ部へ前記ガスを流入させるための流入口に、前記外側エアバッグ部から前記内側エアバッグ部への前記ガスの流入を許容し、前記内側エアバッグ部から前記外側エアバッグ部への前記ガスの流出を制限する逆止弁が設けられており、
前記内側エアバッグ部には、前記外側エアバッグ部から前記内側エアバッグ部へ前記ガスが流入しているときには閉鎖され、前記乗員の頭部拘束時には開放される可変ベントホールが設けられている請求項1~請求項4の何れか1項に記載のシート搭載型エアバッグ装置。 - 前記テザーは、一端部が前記先端チャンバに取り付けられた平面視略「Y」字状に形成されており、シート前後方向に離隔する前側他端部と後側他端部とがそれぞれ前記前後チャンバに取り付けられている請求項1~請求項4の何れか1項に記載のシート搭載型エアバッグ装置。
