Side air bag
First Claim
1. A side air bag for inflation by an inflator mechanism for expanding the side air bag alongside a window of a vehicle, comprising:
- a bag portion formed by two woven fabric panels connected along an outer peripheral portion by a peripheral connecting portion;
said peripheral connecting portion for connecting said two woven fabric panels being formed by weaving a textile structure having a common yarn included in both said two woven fabric panels;
said bag portion sealed over a whole area thereof by an air non-permeable coating material;
a linear connecting portion for partitioning in parallel with a flow direction of an inflator gas formed on a center region of said bag portion by stitching connecting said two woven fabric panels; and
an inflator-side teal portion of the stitching being formed having one of a U-shape or a circular shape.

Abstract
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.
