Air bag device
First Claim
1. An air bag device for a motor vehicle, comprising:
- a gas generator adapted to be mounted on a part of a body of the motor vehicle for discharging gas;
a flange formed around said gas generator;
a hollow air bag having an opening, a peripheral portion of which is coupled to said flange, said air bag being normally housed in a folded condition, and being inflated when gas is discharged from said gas generator; and
a ring-shaped retainer arranged around said gas generator for fixing said peripheral portion of said opening of said gas bag to said flange,said peripheral portion of said air bag being bent along an inside edge of said ring-shaped retainer so as to project vertically upwardly into said air bag, thereby forming a projecting portion which is in contact with said inside edge of said retainer.

Abstract
An air bag device has a gas generator mounted on a vehicle body, and an air bag attached around the gas generator. The air bag is inflated by the gas discharged from the gas generator in an emergency of the motor vehicle. A ring-shaped retainer is arranged around the gas generator for fixing a peripheral portion of an opening of the air bag to a flange formed around the gas generator. The peripheral portion is bent along the inside end of the retainer so as to project into the air bag, thereby forming a saddle-shaped projecting portion which is in contact with the inside end of the retainer. When the air bag is inflated by the gas discharged from the gas generator, and the peripheral portion of the opening of the air bag is pulled outwardly with respect to the gas generator due to a tension applied to the air bag, the saddle-shaped projecting portion abuts the inside end of the retainer, thereby resisting the above tension.
