Abstract
An active vent mechanism for an airbag apparatus that includes a first vent hole formed in an airbag and a patch capable of releasing and closing the first vent hole. A portion of the patch is coupled to the outer surface of the airbag. The airbag apparatus includes a coupling member having one end coupled to the patch and the other end entering the airbag and coupled to the airbag. A portion of the patch or a portion of the coupling member penetrates through an opening in the vicinity of the first vent hole. The airbag apparatus includes a substantially cylindrical regulating member into which the coupling member is inserted inside the airbag. The regulating member has a first end coupled to the inner surface of the airbag so as to surround the opening inside the airbag and a second end coupled to the coupling member in a sealed state.
