Abstract: An air-bag device capable of improving degree of freedom in setting of reaction forces according to physical frames of occupants, a vehicle occupant's lower limb protecting device and a device for protecting an occupant at the time of vehicle side collision using the air-bag device. Knees of an occupant of large build whose inertia load at the time of collision is great are assuredly protected by collective energy absorbing action of the upper cylinders (121, 121) and the lower cylinders (122, 122) at the time of collision. In a case of an occupant of small build whose inertia load at the time of collision is small, loads from the upper cylinders (121, 121) and the lower cylinders (122, 122) are exerted on the occupant in appropriate proportions according to physical size of the occupant to fulfill impact absorption at the time of collision.

Abstract: The inflation and deployment speed of an airbag of a knee-protecting airbag device is increased to quickly deploy the airbag to a position where it can protect the knees of the occupant, thereby improving the occupant protection function. An airbag (10), from a state in which it is arranged in a flat form, is folded sequentially through a first step in which a leading end (10S) is tucked and folded into the airbag (10), a second step in which left and right ends (10M) of the airbag (10) are roll-folded toward each other toward a vehicle-body-side base fabric sheet (12) on the vehicle-body side, and a third step in which the leading end side of the airbag (10) in the deploying direction (F) is roll-folded toward the base end (10T) toward the vehicle-body-side base fabric sheet (12). The folded airbag (10) is accommodated in a case together with an inflator (2), and a base end (10T) thereof is fixed to the case. Thus, an airbag device (1) is produced and is attached to a vehicle, at a position in front of the knees of the occupant.

Abstract: An airbag is inflated and deployed in a short time, and a protective panel is moved rapidly. An airbag device (1) is disposed in a base section (2) of a vehicle. The airbag device (1) is provided with a protective panel (10) covering the base section (2), an airbag (20), and an inflator. The inflator inflates and deploys the airbag (20) by generating a gas. The airbag (20) has at least two standing portions (30) and inflates and deploys between the base section (2) and the protective panel (10). The standing portion (30) stands up from the base section (2) through inflation and moves the protective panel (10).

Abstract: An airbag (10) has a vent hole (18) in one side end portion. One end of a third base fabric (20) is sewn to the airbag (10) through a first sewn portion (23) that closes the vent hole (18), and the other end of the third base fabric 20 is sewn to the other side end portion of the airbag (10) through a second sewn portion (24). The first sewn portion (23) has weaker binding force by sewing than the second sewn portion (24) so that the first sewn portion (23) is separated to open the vent hole (18) when tension force is applied from the third base fabric (20) to the first and second sewn portions (23) and (24).

Abstract: An airbag of a knee-protecting airbag device is prevented from being damaged during inflation and deployment, and the airbag is allowed to deploy evenly on the left and right sides to improve occupant protection function. The inside of an airbag (10) is defined into a plurality of air chambers (21), (22), and (23) by tethers (24) and (25). An inflator (2) accommodated in a diffuser (30) is disposed in the first air chamber (21). The diffuser (30) is provided with an opening (31) that allows gas from the inflator (2) to flow in the airbag (10) and is disposed so as to face the central portion of the first tether (24). This opening (31) is closed in such a manner that it can be opened by the gas from the inflator (2), and the entirety thereof is simultaneously opened by the gas pressure when the airbag (10) deploys. Thus, the gas in the accommodating portion (32) is supplied from the opening (31) to the airbag (10) evenly on the left and right sides. Furthermore, the diffuser (30) protects the airbag (10) from the gas generated by the inflator (2).
