Abstract
An airbag includes a first air chamber and a second air chamber. The first air chamber and the second air chamber are stacked in a thickness direction of the airbag. A reinforcement member is stacked on a non-connection region. The reinforcement member is adjacent to a connection region. The airbag is inflated, the first air chamber and the second air chamber expand in a cavity thickness direction, and the reinforcement member drives the non-connection region of the second main body layer away from the fourth main body layer.
Claims20
An airbag, comprising:
- a first air chamber comprised of a first main body layer and a second main body layer, the first main body layer and the second main body layer are connected and enclose a first cavity;
- a second air chamber comprised of a third main body layer and a fourth main body layer, the third main body layer and the fourth main body layer are connected and enclose a second cavity, and the first cavity communicates with the second cavity;
- and
- a reinforcement member defining a plurality of hollow portions, the plurality of hollow portions are spaced in a length direction of the reinforcement member, and each hollow portion penetrates the reinforcement member in a thickness direction of the first air chamber,
- wherein:
- the first air chamber and the second air chamber are stacked in a thickness direction of the airbag, the second main body layer and the fourth main body layer are partially connected to form a connection region, a region of the second main body layer and a region of the fourth main body layer that are not connected are non-connection regions, the reinforcement member is stacked on the non-connection regions, and the reinforcement member is adjacent to the connection region, and
- when the airbag is inflated, the first cavity and the second cavity are inflated, the first air chamber and the second air chamber expand in the thickness direction of the airbag, and the reinforcement member drives the non-connection region of the second main body layer away from the fourth main body layer .
