Patent ID: 7584987

Claim:
A housing structure of an airbag, comprising: an airbag housing body in which the airbag is installed and in which a plurality of vent holes are formed longitudinally along the airbag housing body and the vent holes are spaced from each other; a partitioning plate installed to the airbag housing body inside of the vent holes to be rotatable inward and outward of the vent holes; a cover plate having a portion that is disposed inside a slot hole formed along the width of the airbag housing body, and has a size large enough to be able to cover perforated regions of the vent holes; and a diffuser, the first end of which is fixed to an outer end portion of the airbag housing body, and is extended into the inner surface of the airbag housing body and the second end of which is connected to the cover plate, thereby allowing gas generated in an inflator to push the cover plate upwards for selectively opening the vent holes by the partitioning plate.
