Description
まず図1を参照すると、エアバッグ1は、膨張可能なカーテンの形態であって、略矩形の形状であるメイン領域2を有し、メイン領域において、第1の膨張可能領域3は、縫い目5によって複数のセル4に分割され、第2の膨張可能領域6は、縫い目8によってセル7に分割されている。2つの膨張可能領域3及び6は、実質的に膨張不能である領域9によって隔てられている。
それぞれのタブは、30゜〜80゜の角度にて傾斜していることが、有利である。
エアバッグの両端部の近くに配置されるタブは、エアバッグの中心の近くに配置されるタブに比べて、より鋭角に傾斜していることが、好都合である。
図2のエアバッグと図1のエアバッグとの間における主要な相違点は、取付タブの特徴にある。図2に示したエアバッグ2の上縁14には、4つの取付タブ20,21,22,23が、互いに間隔を隔て、上縁14に沿ったそれぞれの位置に設けられている。それぞれの取付タブは、織物の単一厚みの層になっていて、各タブにはそれぞれ、ボルト孔24,25,26,27が設けられている。
最も左側のタブ20は、上縁14に対して角度αだけ傾斜しており、この角度は30゜〜80゜の間であるが、本実施形態においては、約45゜になっている。従って、タブ20は、膨張可能なカーテンの最上縁14に対し、極めて急峻に傾斜している。
タブは、従来のホップサックの織り方を用いて織っても良い。
Claims (5)
- エアバッグであって、このエアバッグが、少なくともひとつの膨張可能領域を備え、エアバッグは、複数の取付タブを備えてなる直線状の上縁を有し、それぞれの取付タブは軸線を形成し、それぞれの取付タブの軸線が、エアバッグの中心上方の領域へ向けて内向きに、且つ上記直線状の上縁に対して鋭角に傾斜していることを特徴とするエアバッグ。
- エアバッグは、膨張可能なカーテンの形態であることを特徴とする請求項1に記載のエアバッグ。
- それぞれのタブは、上記直線状の上縁に対して30゜〜80゜の角度にて傾斜していることを特徴とする請求項1又は2に記載のエアバッグ。
- エアバッグの両端部の近くに配置されるタブは、エアバッグの中心の近くに配置されるタブに比べて、より鋭角に傾斜していることを特徴とする請求項1乃至3のいずれか一項に記載のエアバッグ。
- それぞれのタブは織物から形成されていて、織物は直交するたて糸とよこ糸とを有し、それぞれのタブにおける軸線は、たて糸とよこ糸とによって形成される直行軸線に対して鋭角をなしていることを特徴とする請求項1乃至4のいずれか一項に記載のエアバッグ。
