Air-bag for a vehicle
First Claim
1. An airbag for a vehicle, comprising:
- an air cushion;
an inflator that provides gas to the air cushion by generating gas;
a first housing that accepts the inflator, having gas discharge holes that emits gas in sides opposite to each other;
a retainer that fixes the air cushion on its upper surface, comprising a plurality of coupling parts each having a coupling hole corresponding to a respective one of the gas discharge holes in both sides, and coupled to the first housing to move up and down;
a coupling device that couples the coupling part to the first housing; and
a second housing that accepts the air cushion, coupled to an upper portion of the first housing, wherein the gas discharge holes are formed elongated in a upward and downward direction to permit the retainer to move up and down so that a portion of the respective gas discharge holes are opened by movement of the coupling part when spreading the air cushion, and the respective coupling holes keep the gas discharge holes closed by the coupled part when not spreading the air cushion by being arranged in a lower portion of the coupling part.

Abstract
Disclosed is an airbag for a vehicle capable of minimizing gas leakage in an early stage through gas discharge holes in a housing when spreading an air cushion. In both sides opposite to a first housing, the gas discharge holes are formed for emitting gas. A retainer on whose upper surface is fixed the air cushion, and in whose both sides are formed a coupling having coupling holes corresponding to the gas discharge holes, is provided. This coupling part is coupled to the first housing through the coupling device. The gas discharge holes are made lengthwise to make it possible to move the retainer up and down. As a result, when reading the air cushion, some of the holes are opened by movement of the coupling part. Besides, the coupling holes reformed in the lower side of the coupling part, so when not spreading the air cushion, the gas discharge holes are kept closed by the coupling part. In accordance with this structure, it is possible adopt a smaller capacity of the inflator as it can efficiently control the gas emitted to the outside through the gas discharge holes in the early stage of spreading the air cushion.
