Airbag device
First Claim
1. An airbag device comprising:
- an airbag that can be inflated and deployed so as to cover a wall of a vehicle by introducing gas; and
an inflator, having a main body, that discharges gas radially from a plurality of gas discharge ports disposed at one end of said body to supply the gas into an air chamber inside of the airbag,wherein the airbag has a gas inlet to which the inflator is attached and the air chamber is inflated by the gas from the gas inlet,wherein the airbag device has a fabric member that is formed of a single belt-like piece and is wound around the inflator several times in sequentially layered manner such that the fabric member encloses the plurality of gas discharge ports and opens to the inside of the airbag and is inflated by the gas pressure acting thereon and shifted in the circumferential direction thereof when the inflator is activated, andwherein the fabric member and the plurality of gas discharge ports of the inflator being inserted together into the gas inlet towards the air chamber inside of the airbag.

Abstract
Gas supplied from gas discharge ports is guided without providing a metal guide tube on the inflator of an airbag device, and the airbag is protected from the gas. An inner tube (50) is connected to a gas inlet (13) formed in an airbag (10), and an inflator (40) around which a fabric member (60) is wound is inserted into and attached to a gas passage (54) formed in the inner tube (50). The fabric member (60) is wound around the inflator (40) several times into a tubular shape such that it covers a plurality of gas discharge ports (42) provided in the inflator (40) and such that one end thereof opens to the inside of the airbag (10), and the fabric member (60) is inserted into the inner tube (50). When the inflator (40) is activated, gas from the gas discharge ports (42) is guided to the inside of the inner tube (50) by the fabric member (60) and is guided and supplied to air chambers (31) and (32) through the gas passage (54), thereby inflating and deploying the airbag (10).
