  • Publication number: 20050248131
    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: 20050230941
    Abstract: In a knee protecting airbag device of the present invention, an airbag is folded and housed on the front side of the knees of a seated passenger. The airbag is protruded rearward of a vehicle from a protruding opening and expanded and inflated upward, when an inflating gas flows in. And, the airbag is arranged on the front side of the knees of the passenger between a member on the body side and the knees of the passenger thereby to protect the knees of the passenger. The protruding opening has a transverse width size set within a range of ? to ? of the transverse width size of the airbag having completed its expansion and inflation.

  • Publication number: 20050206136
    Abstract: An airbag apparatus has an airbag, an inflator, a cover and an opening mechanism. When an impact the magnitude of which is greater than a predetermined value is applied to the vehicle, the inflator supplies gas to the airbag. The cover covers the airbag. The opening mechanism opens the cover prior to inflation of the airbag.

  • Patent number: 6942245
    Abstract: A knee protecting airbag device (M1), wherein an airbag (26) covers the substantial lower surface (9a) of a column cover (9) protruded to a driver side. Therefore, the airbag is minimized in the capacity without deteriorating the protection of the knee of the driver. As a result, it is possible to shorten the time period required for the airbag to complete the expansion and inflation. The airbag has a generally plate shape capable of covering at least the lower surface of the column cover when it completes the inflation. Even if the knee of the driver comes close to the column cover when the driver depresses a brake pedal or the like, the airbag being expanded and inflated is smoothly arranged in a narrow space between the knee of the driver and the column cover lower surface without interfering with the knee of the driver.

  • Patent number: 6920954
    Abstract: A pedestrian protection airbag system includes a control unit, an airbag, an inflator, a movement unit for moving a cover member to thereby allow the airbag to thrust out from an airbag storage portion smoothly, and a drawing unit for drawing out the airbag. The control unit receives signals from sensors, and can perform detection in two stages. In one of the stages the control unit performs touch detection such that the control unit can anticipate that a vehicle will touch a pedestrian, while in the other stage the control unit performs approach detection before the touch detection such that the control unit detects the pedestrian approaching the vehicle. The movement unit and the drawing unit are actuated by the control unit detecting a pedestrian approaching the vehicle. The inflator is actuated by the control unit detecting calculated touch to the pedestrian.

  • Publication number: 20050127644
    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: 20040160042
    Abstract: A knee protecting airbag device comprises an airbag, an inflator, and a case housing the airbag and the inflator and arranged in front of a passenger. When the airbag extends and expands, it protrudes toward the rear of the vehicle from the opening of the case, to protect the knees of the passenger. The knee protecting airbag device further comprises a holding member having a mounting portion for mounting the knee protecting airbag device on the vehicle. The holding member holds the case. In the holding member, there are formed a communication hole and a support face arranged on the periphery of the communication hole. The communicating hole communicates with the opening of the case and allows the airbag extending and expanding to protrude therethrough. The support face can support the vehicle front side face of the extending and expanding airbag.

  • Publication number: 20040124615
    Abstract: A side airbag device (10) for protecting an occupant (P) from a side impact applied to a body (15). The inside of the airbag (18) is divided into an upper chamber and a lower chamber. A connecting portion (24) is formed by joining the inside surfaces of the airbag. The flow of the inflation gas is distributed to the upper chamber and the lower chamber by the connecting portion.

  • Patent number: 6752417
    Abstract: A knee protecting airbag device includes a folded airbag housed below a member attached to the vehicle body and in front of the knees of a seated passenger. The airbag extends and expands when fed with an inflating gas toward the rear of the vehicle to protect the knees of the passenger. The airbag includes a lower expansion portion, which is upstream in the flow of the gas, and an upper expansion portion, which is downstream. The lower expansion portion protrudes toward the rear of the vehicle to protect the knees. The upper expansion portion protrudes upward from the lower expansion portion. The airbag properly protects the knees of the passenger by extending and expanding efficiently, taking into account the time elapsed, until completion of the extension and expansion.
