Title:
HOLLOW WEAVE AIR BAG
Document Type and Number:
Japanese Patent JP3707282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hollow weave air bag improving an internal pressure maintaining performance without any increase in costs.
SOLUTION: In a peripheral area including a boundary part 24 with a bag- shaped part circumferential edge part (closed part) 14 of a hollow weave bag 10, a triple weave part 26 and a quadruple weave part 28 with thread density lower than that of the circumferential edge part 14 are formed. When the outside surface of the hollow weave air bag 10 is coated, a coating layer 20 is formed on the front face side, and additionally, a coating layer 30 is also formed on the back face side because a coating agent permeates the triple weave part 26 and the quadruple weave part 28 to the back face side. Therefore, a stretch of a seam due to concentration of stress is hardly caused, and gas leakage is hardly caused even if the seam is stretched. In this way, internal pressure maintaining performance of the hollow weave air bag 10 can be improved.
