Side air bag

摘要

A side air bag expands near a window at a time of collision of a vehicle to restrain an occupant from moving in a lateral direction. The air bag has an expansion duration protracted to constrain the occupant during overturning of the vehicle. Stowability for stowing the air bag in a folded state in a side structure of the vehicle, such as a pillar and a roof side rail portion, is enhanced in that two woven fabrics are connected along an outer peripheral portion to form a bag portion a textile structure woven using a common yarn include in both fabrics. A whole of the bag portion is coated and sealed by an air non-permeable coating material to improve air tightness. A mounting portion for mounting the air bag in the side structure, such as a pillar or a roof side rail, is integrally formed by extending the woven fabrics or the common-yarn textile structure portion outward from the outer peripheral connection portion, thereby improving stowability.
