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.

Claims

1. An airbag comprising:

a tab that is inserted into and supported by a substantially flat-plate-shaped bracket disposed on a vehicle,

said tab having, in plan view,

a first slit extending along a direction substantially orthogonal to a direction of inflation and deployment of said airbag, and allowing insertion of said bracket in a normal time, and

a second slit that opens into a point at one end portion or on an intermediate portion of said first slit at an angle intersecting with said first slit.

2. The airbag according to claim 1, wherein

said second slit extends at least on a side opposite to said direction of inflation and deployment with respect to said first slit.

3. The airbag according to claim 1, wherein

said second slit opens into said first slit at a point closer to a side of application of a load component to said tab along a direction of extension of said first slit at the time of inflation and deployment of said airbag.

4. The airbag according to claim 1, wherein

said first slit includes a third slit that extends from a range of insertion of said bracket in the normal time towards a side opposite to said side of application of a load component to said tab along said direction of extension of said first slit at said time of inflation and deployment of said airbag.

5. An airbag apparatus comprising:

the airbag according to claim 1; and

an inflator that supplies gas for inflation and deployment of said airbag into said interior of said airbag.
