Abstract
An airbag apparatus comprising an airbag that expands between a vehicle occupant and a side wall of a vehicle body. The airbag is divided into a plurality of expanding chambers that are connected by a plurality of gas flow channels. Among the expanding chambers, the cross-sectional area of the gas flow channel leading to the expanding chamber that expands first is the largest, the cross-sectional area of the gas flow channel leading to the expanding chamber that expands last is the smallest, and the expanding chambers expand in stages.
Claims13
An airbag apparatus comprising:
- an inflator for discharging gas;
- and
- an airbag that is caused to expand by being filled with the gas, wherein
- the interior of the airbag is divided into a plurality of expanding chambers,
- the expanding chambers have flow channels for guiding gas to the expanding chambers, and
- the cross-sectional area of each of the gas flow channels is different so that the expanding chambers are caused to expand in stages at different times.
An airbag apparatus comprising:
- an inflator for discharging gas;
- and
- an airbag that is filled with the gas and is thereby caused to expand between a side wall of a vehicle body and a side part of a vehicle occupant that extends from a lumbar region to a shoulder region, wherein
- the airbag is divided into a plurality of expanding chambers;
- the expanding chambers are connected by gas flow channels, and
- a design is employed whereby the cross-sectional area of the gas flow channel of the expanding chamber that expands first among the expanding chambers is the largest, and the cross-sectional areas of the gas flow channels of the expanding chamber that expands last are the smallest.
