  • Patent number: 7264267
    Abstract: The head-protecting airbag device (M1) includes an airbag (12) provided with a gas admissive portion (13) and a non-admissive portion (23). The gas admissive portion (13) includes a gas feed passage (14) for feeding inflation gas G toward both front and rearwards of the vehicle, and a plurality of vertical chambers (17) juxtaposed along front-rear direction of the vehicle. Each of the vertical chambers (17) includes a communication port at its upper end for communicating with the gas feed passage (14). The substantial lengths of a vehicle's outer wall (13b) and an inner wall (13a) of the airbag (12) are differentiated from each other by a belt (31) in the periphery (19) of the communication port (18). Thus the periphery (19) of the communication port (18) guides inflation gas (G) obliquely down and toward the vehicle's exterior (O) when inflation gas (G) flows into the vertical chamber (17) via the communication port.

  • Publication number: 20070170707
    Abstract: A side airbag apparatus for vehicle has an airbag and an inflator. An upper chamber, a lower chamber, and an intermediate chamber are defined by a seam in the airbag. When the airbag is deployed, the upper chamber corresponds to a shoulder of an occupant, the lower chamber corresponds to a lumbar region of the occupant, and the intermediate chamber corresponds to a thorax of the occupant. The seam guides gas from the inflator to the upper and lower chambers such that the upper and lower chambers are substantially simultaneously inflated, and the intermediate chamber is inflated after a delay. The thickness of the intermediate chamber is less than the thicknesses of the upper and lower chambers. As a result, the occupant of the vehicle is effectively protected.

  • Patent number: 7234727
    Abstract: A first airbag apparatus of the present invention has an airbag module, which includes an airbag and an inflator, and a displacement mechanism, which displaces the airbag module. The displacement mechanism displaces the airbag module from an original position to a predetermined position when a collision of the vehicle is predicted and displaces the airbag module from the predetermined position to the original position when the predicted collision is avoided. A second airbag apparatus of the present invention has the airbag module and the displacement mechanism, which displaces a support member. The support member displaces the airbag from the original position to the predetermined position before the airbag is deployed. The deployed airbag is supported between the support body that is displaced to the predetermined position and an occupant.

  • Publication number: 20070132215
    Abstract: In a knee protecting airbag device (M1), an airbag (26) folded and housed below a steering column (3) is expanded and inflated while rising from the lower side of the steering column (3) along a column cover lower surface (9a) during an inflation process. The shape of the airbag having completed the inflation is in a generally plate shape capable of covering at least the lower surface of the column cover. Even if the knee of the driver comes close to the column cover when the driver depressing a brake pedal, therefore, the airbag being expanded and inflated goes smoothly into the clearance between the knee of the driver and the column cover lower surface. The airbag having completed the expansion and inflation protects the knee of the driver properly so that the knee may not interfere with the column cover.
