ABSTRACT:
FIELD OF THE INVENTION AND RELATED ART STATEMENT
The present invention relates to an airbag device with an inflator installed in a vehicle. More particularly, the present invention relates to an airbag device of a so-called aspiration type, which aspirates air when an airbag is inflated with gas from an inflator.
An airbag device for protecting an occupant during a vehicle collision or roll-over is structured so that an airbag thereof is inflated by gas from an inflator. By making the device to aspirate air into the inflating airbag, the inflating speed of the airbag can be increased. An airbag of such a type which aspirates air during the inflation of the airbag is sometimes called as an aspiration-type airbag.
Most of aspiration-type airbags for drivers are structured to aspirate air through vent holes formed in the airbags. Some of aspiration-type airbags for occupants in passenger seats or rear seats use such vent holes. As one of aspiration-type airbag devices for occupants in passenger seats or rear seats, an airbag device, in which an air through opening is formed in a casing for accommodating an airbag, has been proposed.
OBJECT AND SUMMARY OF THE INVENTION
It is an object of the present invention to an air bag device with an inflator having an air vent portion for aspirating air formed in itself, not in an airbag or a casing.
An inflator of the present invention used for supplying gas into an airbag to inflate the airbag, has a gas outlet, a front-side portion confronting the airbag, and a rear-side portion opposite to the front-side portion. An air vent hole communicates between the front-side portion and the rear-side portion.
As described above, the inflator of this invention is provided with an air vent hole formed in itself, thereby avoiding the necessity of forming a hole for the aspirating air in an airbag or a casing or allowing the minimization of the hole.
