Abstract: A curtain airbag of a vehicle is provided adjacent to the roof of the vehicle in a folded state, is configured to have a shape that unfolds downward between an inner side surface of the vehicle and an occupant when the vehicle crashes, and includes an outer panel that proceeds toward the side surface of the vehicle and an inner panel that proceeds toward the occupant upon expansion. The curtain airbag further includes a head support part configured to have a shape in which an expansion thickness, which is defined by the outer panel and the inner panel in a portion that the head of the occupant contacts due to the car crash, gradually increases toward the front of the vehicle, so as to prevent the head of the occupant from rotating while moving toward the front of the vehicle. The curtain airbag may effectively stop the head of the occupant from rotating while moving toward the front of the vehicle during a vehicle crash.

Abstract: The present invention relates to a vehicular airbag device provided with a configuration comprising: an airbag cushion which is formed in a shawl shape so as to surround and restrict the entire upper body around both shoulders of an occupant as well as the abdominal and pelvic regions in the event of a vehicle collision, and deployed toward both side surfaces of the occupant; and a limiting means which is installed in first and second cushions of the airbag cushion deployed at both sides of the occupant, and provides a supporting force and limits the deployment shape of the first and second cushions at the time of deployment of the first and second cushions. According to the present invention, both side surfaces and the front surface of the occupant are efficiently restricted by improving the lateral strength of the airbag cushion to safely protect the occupant in the event of a vehicle collision.

Abstract: An airbag device for a vehicle includes a curtain airbag that is deployed downward along an inner side surface of a vehicle; and a driver's seat airbag that expands from inside the steering wheel of the vehicle toward the rear of the vehicle, and is configured so that when the curtain airbag and the driver's seat airbag expand, a thickness portion of the driver's seat airbag along a direction of front to back of the vehicle is arrested by the inner face of the leading edge of the curtain airbag, keeping the head of the driver from pushing aside the curtain airbag and the driver's seat airbag and being projected toward the front of the vehicle.
