Abstract
自動車のためのエアバッグアセンブリは、膨張可能なエアバッグと、補強ラッパーとを含む。膨張可能なエアバッグは、長手方向に延びる軸を有し、格納状態において回転軸を中心として巻かれている。補強ラッパーは、膨張可能なエアバッグの長手方向に延びる第1の側近接の膨張可能なエアバッグに結合されており、回転軸を中心として巻かれており、膨張可能なエアバッグの少なくとも第1の部分の周り全体に巻き付けられている。膨張可能なエアバッグ及び補強ラッパーは、エアバッグアセンブリの単調に巻かれた部分を画定するように協働する。ある用途では、補強ラッパーは、膨張可能なエアバッグを自動車内に吊り下げるために使用されるタブに固定されている。
