Abstract

A vehicle air bag device having an air bag that is formed integrally with an inflator insertion portion into which an inflator is inserted. The air bag device also includes a bracket that is formed to attach the inflator to a vehicle body side, and that includes an inflator side mounting portion mounted onto an outer side of the inflator insertion portion so as to partially cover the inflator insertion portion; a strip-form body that surrounds and integrates the inflator side mounting portion and the inflator disposed in the inflator insertion portion; and a seal portion that is formed on the inflator side mounting portion in alignment with the strip-form body.

Claims

1. A vehicle air bag device comprising:

an air bag having an integrally formed inflator insertion portion;

a gas discharging inflator disposed within said inflator insertion portion, wherein, when the gas is discharged by the inflator, the gas flows into the airbag, thereby inflating and deploying the airbag;

a bracket configured to attach said inflator to a vehicle body, said bracket being mounted over an external surface of said inflator insertion portion and at least a portion of said inflator disposed therein, said bracket partially covering said inflator insertion portion; and

a strip-form body disposed around an external portion of said bracket, said inflator insertion portion of said airbag, and said inflator disposed in said inflator insertion portion,

wherein said bracket comprises a reduced thickness portion, said reduced thickness portion having a reduced thickness extending in a direction toward an inflator insertion portion front surface, said reduced thickness portion connecting said front surface of said inflator insertion portion and said bracket in series in alignment with said strip-form body; and

wherein said bracket comprises a seal portion, said seal portion being in sealing alignment with said strip-form body to seal a gap disposed between said strip-form body and said front surface of said inflator insertion portion.

2. The vehicle air bag device according to claim 1, wherein said reduced thickness portion is disposed in a position that is surrounded by said strip-form body, and said seal portion is disposed on at least one of a pair of side edges of said strip-form body.
