WIPO Patent Application WO/2019/049930

Kind Code:

A1

Abstract:

Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.
