  • Patent number: 8840134
    Abstract: A vehicle airbag arrangement comprises a deployable airbag having a packed state and a deployed state, and a gas generator adapted to supply gas to deploy the airbag from the packed state to the deployed state. At least during initial deployment of the airbag, the gas generator may emit a gas flow substantially in a pre-selected direction. When the airbag is in the packed state, a portion of the airbag forms a starting pocket comprising two panels with an intermediate apex which extend substantially parallel to the pre-selected direction, the starting pocket positioned with the intermediate apex aligned with the pre-selected direction, such that the starting pocket, during the initial deployment of the airbag, initially receives the gas flow, thereby deploying the starting pocket in the pre-selected direction. Such an airbag arrangement may be included in a vehicle seat. A corresponding method of packing an airbag may achieve the airbag arrangement.
