Abstract: A driver side airbag device with an airbag module including a steering wheel, an inflator, and a cushion. The steering wheel includes a housing portion that stores the airbag module and a cover member that seals the housing portion. The cover member has a design region on an occupant side, and a thin-walled portion formed from an upper portion region to a lower portion region of the design region that is cleaved open by an expansion pressure of the cushion to open cover doors. The thin-walled portion has a first plate thickness portion and a second plate thickness portion that is thinner than the first plate thickness portion. The second plate thickness portion is formed in the lower portion region of the design region.

Abstract: PROBLEM:
To provide a side airbag device that can be stored compactly.
RESOLUTION MEANS
The present invention is an airbag device to be stowed in a vehicle seat, comprising:
an airbag cushion that restrains an occupant by expanding and deploying;
an inflator arranged on the inner side of the seat frame which supplies expansion gas to the airbag cushion; and
a cover member made of a ductile material that melts and shrinks under heat and pressure to retain the airbag cushion. The airbag cushion includes a rear chamber section where the inflator is stowed, and a front chamber section that extends forward from the rear chamber section that is arranged outside of the seat frame when stowed. The cover member is then configured to heat and pressurize the region corresponding to the front chamber section of the airbag cushion, thereby pressurizing and retaining the relevant section of the airbag cushion.

Abstract: A steering wheel having a retaining spring has a pin engagement section that engages with a pin of an airbag module that is positioned inside a mounting hole to install the airbag module on a core bar. A base section of the core bar is provided with a spring mounting section to which the retaining spring is mounted. The spring mounting section includes a main body column section that protrudes from a base surface of the base section and an extension, a base end thereof connected to the main body column section and extending from the main body column section. A mounting section of the retaining spring is positioned between the base surface and the extension and mounted so as to sandwich the main body column section.

Abstract: Gas generator comprising:



a chamber with an outlet port,
breakable sealing means.
pressurized gas stored in the chamber,
an insert nozzle positioned in the chamber, comprising at least three intermediate orifices and positioned between the gas outlet and at least some of the pressurized gas, characterized in that the insert nozzle is arranged to deform after the breakable sealing means are ruptured, during the application of a pressure difference between a downstream face and an upstream face of the insert nozzle exerted by said at least some of the pressurized gas.
