Abstract

An airbag that can easily restrain a pressure at an initial stage of expansion is to be provided. A case is designed to have a large width dimension. The width dimension is set to be not less than 2.0 times but not more than 3.0 times a width dimension of a head portion of an AC06 type dummy A for a vehicle collision experiment. Two disk-shaped inflators are attached to the base portion of the case. Even when the airbag is activated when the dummy A is close to a lid covering the airbag, the airbag can expand toward both sides of the dummy A, thereby easily alleviating an impact applied to the dummy A.

Claims

1. An airbag apparatus comprising:

an airbag inflated and expanded by an inflow of a gas;

an inflator supplying said gas to said airbag; and

a case accommodating therein said airbag in a folded state and provided with an opening through which said folded airbag is to inflate outward,

wherein a width dimension of said opening is not less than 2.0 times, but not more than 3.0 times the width dimension of an object to be protected.

2. An airbag apparatus according to claim 1 to be installed in a vehicle, arranged in a widthwise direction thereof aligned with that of said vehicle,

wherein a width dimension of said object to be protected is in accordance with a width dimension of a head portion of an AC06 type dummy for a vehicle collision experiment.

3. An airbag apparatus according to claim 1, further comprising a lid openably covering said opening of said case, wherein an area of said lid is not less than 26,000 mm² but not more than 60,000 mm².

4. An airbag apparatus according to claim 1, wherein a maximum output of said inflator is not more than 380 kPa.

5. An airbag apparatus according to claim 1, comprising a plurality of inflators,

wherein a maximum output of a first one of said inflators, to be initially activated when activating said inflators, is not more than 380 kPa.
