Description
内部に膨張用ガスを流入させて膨張するバッグ本体と、バッグ本体の膨張完了形状を規制する規制手段と、を有する構成とされ、
バッグ本体が、膨張完了形状を、左右方向に略沿って貫通する中空部を有し、中空部の周囲を、上下両側において前後方向に略沿うように配置される上側膨張部及び下側膨張部と、前後両側において上下方向に略沿うように配置される前側膨張部及び後側膨張部と、によって囲まれる略四角筒形状として、膨張完了時に乗員側に配置される後側膨張部を、乗員を保護可能な乗員保護部とし、膨張完了時における前端側に、収納部位側に取り付けられる取付部を、配設させる構成とされ、
規制手段が、バッグ本体の左右方向側の中央を中心として左右対称となる複数箇所に、配設されるとともに、それぞれ、左右方向の側方から見て、中空部を跨ぐようにして、少なくとも上縁側と下縁側とを、バッグ本体側に連結される構成とされていることを特徴とする。
バッグ本体において、内周パネル部と閉塞パネルとによって囲まれた領域を、ガス貯留部として、構成することが、好ましい。
Claims (2)
- 車両において助手席に着座した乗員の前方側におけるインストルメントパネルの内部に折り畳まれて収納され、内部に膨張用ガスを流入させて収納部位から後方側に向かって突出するように展開膨張し、前記乗員を保護可能に構成される助手席用のエアバッグであって、
内部に膨張用ガスを流入させて膨張するバッグ本体と、該バッグ本体の膨張完了形状を規制する規制手段と、を有する構成とされ、
前記バッグ本体が、膨張完了形状を、左右方向に略沿って貫通する中空部を有し、該中空部の周囲を、上下両側において前後方向に略沿うように配置される上側膨張部及び下側膨張部と、前後両側において上下方向に略沿うように配置される前側膨張部及び後側膨張部と、によって囲まれる略四角筒形状として、膨張完了時に前記乗員側に配置される前記後側膨張部を、前記乗員を保護可能な乗員保護部とし、膨張完了時における前端側に、前記収納部位側に取り付けられる取付部を、配設させる構成とされ、
