Abstract
A side airbag apparatus may include: an inflator configured to discharge gas; and a cushion deployed to one side of a passenger by the gas discharged from the inflator, and having a main chamber and a push chamber, which are formed therein, wherein the push chamber is inflated to protrude from the main chamber toward an indoor side, and pushes up an arm the passenger, wherein the cushion comprises a first panel disposed at a side surface of a vehicle body; a second panel stacked on an indoor side of the first panel, and configured to form the main chamber and the push chamber with the first panel; and a tether member inserted between the first and second panels, having one end coupled to the first panel and the other end coupled to the second panel.
Claims8
A side airbag apparatus comprising:
- an inflator configured to discharge gas;
- and
- a cushion deployed to one side of a passenger by the gas discharged from the inflator, and having a main chamber and a push chamber, which are formed therein, wherein the push chamber is inflated to protrude from the main chamber toward an indoor side, and pushes up an arm the passenger,
- wherein the cushion comprises:
- a first panel disposed at a side surface of a vehicle body;
- a second panel stacked on an indoor side of the first panel, and configured to form the main chamber and the push chamber with the first panel;
- and
- a tether member inserted between the first and second panels, having one end coupled to the first panel and another end coupled to the second panel, and configured to form the push chamber by pulling the second panel when the cushion is deployed.
A method for manufacturing a side airbag apparatus, comprising:
- a first step of preparing a first panel and a second panel which is to be disposed in a direction facing a passenger from the first panel, when a cushion is deployed;
- a second step of coupling one end of a tether member to the first panel, and coupling another end of the tether member to the second panel;
- and
- a third step of overlapping the first and second panels such that the tether member is interposed between the first and second panels, and then sewing edges of the first and second panels,
- wherein when the cushion is deployed, a push chamber is formed at a lower region of the cushion by tension of the tether member, and inflated to protrude and push up an arm of the passenger.
