Airbag
First Claim
1. An air bag that is connected to an inflator provided with a gas outlet port for ejecting expansion gas on a tip end side, the air bag comprising:
- an air bag main body that is formed of a sheet material with flexibility so as to be able to be folded; and
a guide member that has a shape holding property,wherein the air bag main body includesan expansion portion that expands with expansion gas flowing from the inflator, anda tubular connecting port, which is connected to the inflator by inserting a side of a gas outlet port of the inflator thereinto, to cause the expansion gas to flow into the expansion portion, andwherein the guide member is attached to the connecting port of the air bag main body and maintains an opening state of the connecting port so as to be able to guide the insertion of the side of the gas outlet port of the inflator,wherein the guide member includes an attachment hole that penetrates through inner and outer circumferences of the guide member,wherein the connecting port of the air bag main body includes an attachment sheet portion that covers the attachment hole and a circumferential edge of the attachment hole on an outer circumferential side or an inner circumferential side of the guide member,wherein the attachment sheet portion faces the sheet material constituting the connecting port of the air bag main body across the attachment hole;
wherein the air bag includes a welded portion that welds the attachment sheet portion and the sheet material constituting the connecting port together at the location of the attachment hole; and
wherein the guide member is attached to the connecting port with the welded portion.

Abstract
An air bag includes an air bag main body and a guide member. The air bag main body includes an expansion portion that expands with expansion gas flowing from an inflator and a tubular connecting port, which is connected to the inflator by inserting a side of a gas outlet port of the inflator thereinto, to cause the expansion gas to flow into the expansion portion, and is formed of a sheet material with flexibility so as to be able to be folded. The guide member has a shape holding property of maintaining an opening state of the connecting port so as to be able to be attached to the connecting port of the air bag main body and guide the insertion of the inflator into the side of the gas outlet port.
