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.
