Airbag apparatus and method of manufacturing airbag
First Claim
1. An airbag apparatus comprising:
- an airbag disposed in front of a passenger to be inflated toward a rear side of a vehicle for protecting the passenger in case of a vehicle accident, said airbag including a center side airbag section located in a center area of the vehicle in a width direction of the vehicle, said center side airbag section extending vertically at the center area of the vehicle in an inflated state and having highest and lowest portions in a vertical direction and front and rear portions in a front-rear direction of a vehicle, a window side airbag section located at a window side of the vehicle in the width direction, said window side airbag section extending vertically at a window side of the vehicle in the inflated state and having highest and lowest portions in the vertical direction and front and rear portions in the front-rear direction, and an upper edge extending between the center side airbag section and the window side airbag section in the inflated state, said upper edge at the window side airbag section being lower than that at the center side airbag section so that the window side airbag section does not interfere with a side portion of the vehicle, anda gas supply device for supplying gas to inflate the vehicle airbag,wherein a length between the highest and lowest portions of the center side airbag section is greater than a length between the front and rear portions of the center side airbag section, and a length between the highest and lowest portions of the window side airbag section is greater than a length between the front and rear portions of the window side airbag section.

Abstract
An airbag apparatus to be mounted on a vehicle such as a motor vehicle includes an airbag and a gas supply device. The airbag is inflated to a rear side of a vehicle from a front side thereof in front of a vehicle passenger for protecting the passenger in case of a vehicle accident. The airbag includes a right airbag section extending vertically on a right side of the vehicle and a left airbag section extending vertically on a left side of the vehicle in the inflated state. The right or left airbag section located closer to a side portion of the vehicle has an upper edge lower than that of the left or right airbag section, so that the right or left airbag section does not interfere with the side portion.

8. A method of manufacturing an airbag, comprising:
-
preparing a first panel corresponding to a center side airbag section to be located at a center area of a vehicle in a width direction, a second panel corresponding to a window side airbag section to be located at a window side of the vehicle in the width direction, and a third panel, said second panel being smaller than the first panel and formed asymmetrically with respect to the first panel, fabricating the first and second panels so that the first panel has a vertical length greater than that of the second panel, and connecting the first, second and third panels to form a bag-shaped airbag, said third panel being interposed between the first and second panels so that an upper edge extends between the center side airbag section and the window side airbag section, is located in a highest portion of the airbag in an inflated state and decreases from the center side airbag section to the window side airbag section in the inflated state. - View Dependent Claims (9)

10. An airbag apparatus comprising:
-
an airbag disposed in front of a passenger to be inflated toward a rear side of a vehicle for protecting the passenger in case of a vehicle accident, said airbag including a center side airbag section located in a center area of the vehicle in a width direction of the vehicle, said center side airbag section extending vertically at the center area of the vehicle in an inflated state in a front-rear direction, a window side airbag section located at a window side of the vehicle in the width direction, said window side airbag section extending vertically at a window side of the vehicle in the inflated state in the front-rear direction, and an upper edge extending between the center side airbag section and the window side airbag section in the inflated state, said upper edge at the window side airbag section being lower than that at the center side airbag section so that the window side airbag section does not interfere with a side portion of the vehicle, and a gas supply device for supplying gas to inflate the vehicle airbag, wherein said airbag further includes a front side facing the passenger, a curved upper portion extending from the front side to a back side at a side opposite to the front side through the upper edge, and a curved lower portion extending from the front side to the back side through a lower edge extending substantially horizontally in the inflated state, the curved upper portion has a size greater than that of the curved lower portion when viewed from a side of the airbag, and the curved lower portion at the center side airbag section has a shape same as that of the window side airbag section, and has a semi-circular shape. - View Dependent Claims (11)
