SINGLE PIECE AIR BAG WITH IMPROVED STRESS DISTRIBUTION

摘要

An inflatable air bag (20') having an inlet (24) adapted to be attached to a source of inflation gas (70), initially maintained in a folded configuration prior to being inflated, the air bag being rapidly inflated by the inflation gas creating certain stresses within the material, the air bag including a plurality of seams (90) formed along joined arcuate edges of a single piece of material (50), wherein the seams are arranged about the air bag at locations remote from the location of maximum stress.
