Disclosed is an airbag apparatus capable of safely protecting a passenger by increasing the width of an airbag cushion in a leftward-rightward direction when the passenger comes into contact with the airbag cushion. The airbag apparatus includes: a first tether disposed inside the airbag cushion in a forward-backward direction, and a second tether disposed inside the airbag cushion in the leftward-rightward direction and connected to the first tether. When the passenger comes into contact with the airbag cushion upon deployment of the airbag cushion, the width of the airbag cushion in the leftward-rightward direction is increased.

[Problem] To provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a passenger protection apparatus including this side airbag apparatus. [Resolution means] The airbag employed in the present invention includes: a first chamber (C1) which houses the inflator and is deployed outside in the vehicle width direction of the frame side wall part; a second chamber (C2) which is deployed inside in the vehicle width direction of the frame side wall part; and a gas guide (100) arranged so as to surround the inflator inside the first chamber. In addition, the first chamber (C1) is deployed such that at least a portion thereof, as seen from the vehicle side, overlaps the frame side wall part. A first inner vent is formed at the boundary part between the gas guide and the first chamber, with gas introduced from the gas guide to the first chamber via this first inner vent. Moreover, a second inner vent is formed at the boundary part between the gas guide and the second chamber, with gas introduced from the gas guide to the second chamber via this second inner vent.

A roof airbag for vehicles is proposed. The roof airbag includes: a main chamber configured to be deployed as gas is introduced therein through a diffuser; and an overlap chamber into which the gas may be introduced and configured to be deployed into a shape that overlaps the main chamber around the diffuser.

A control valve provided in a communicating portion restricts the supply of gas from a front main chamber to a rear delay chamber during an initial stage of inflation and deployment of the front main chamber. The control valve releases restriction of the supply of the gas from the front main chamber to the rear delay chamber during the later stage of inflation and deployment of the front main chamber.

An inflatable airbag system can be configured to be mounted to a frontal region of a vehicle. The inflatable airbag system includes a housing configured to be mounted on a steering wheel of a vehicle and an inflator assembly at least partially disposed within the housing. The inflatable airbag system includes an airbag that receives inflation gas from the inflator assembly to expand and deploy out of the housing from a packaged configuration to a deployed configuration to provide occupant crash protection during a collision event, the airbag defining an inflatable chamber. A diffuser is disposed within the inflatable chamber and is in fluid communication with the inflator assembly. An occupant-facing panel of the diffuser comprises an aperture disposed in the center of the occupant-facing panel of the diffuser.
