  • Patent number: 9434343
    Abstract: An airbag and an airbag device are provided in which a posture of inflation and deployment of the airbag can be held easily and simply even if the airbag is mounted on an instrument panel having a convex portion in the space of inflation and deployment of the airbag. An airbag device includes an airbag that is folded and housed in an opening portion of an instrument panel during a normal state and is inflated and deployed on a surface of the instrument panel by gas supplied in an emergency; an inflator that supplies gas to the airbag; a retainer that holds the airbag and the inflator; and an airbag cover that covers the airbag and configures a part of the instrument panel, in which the airbag has a concave portion formed in both lower side portions when the airbag is inflated and deployed.

  • Patent number: 9199598
    Abstract: An airbag includes a tab that is inserted into and supported by a substantially flat-plate-shaped bracket disposed on a vehicle. The tab has a first slit extending along a direction substantially orthogonal to a direction of inflation and deployment of the airbag in plan view. The first slit allows insertion of the bracket in a normal time. The tab further has a second slit opening into a point at one end portion or on an intermediate portion of the first slit at an angle intersecting with the first slit in plan view.

  • Patent number: 8465049
    Abstract: An airbag and an airbag device can support itself without using the reaction force from a front glass and cost reduction and commonality of components are achieved. An airbag of the present invention is normally accommodated in an instrument panel in a folded state and is inflated and deployed between a front glass and an occupant by gas being supplied thereto in an emergency. The airbag has rectification means disposed therein that controls the flow of the gas. The rectification means has a first opening through which gas is supplied such that part of the airbag on the occupant side is pressed against the instrument panel, a second opening through which gas is supplied such that the airbag is lifted upward, and a third opening through which the gas is supplied to a base end portion of the airbag on the front glass side.

  • Patent number: 7841622
    Abstract: The area of panels used in an airbag that inflates so that a recess extends in the vertical direction between a left chamber and a right chamber. The airbag 1 includes a front chamber 2 positioned in the forefront when viewed from the position of an occupant, the left chamber 3 communicating with the front chamber 2 to be inflated on the left side in front of the occupant, and the right chamber 4 communicating with the front chamber 2 to be inflated on the right side in front of the occupant. In a state in which the airbag 1 is inflated, there is no extending member such as a tie panel between the distal parts of the left chamber 3 and the right chamber 4, and a recess 6 formed between the distal parts of the left chamber 3 and the right chamber 4 opens toward the occupant, and continuously extends from the upper part of the airbag 1 to the lower part thereof.
