ABSTRACT:
An air bag device includes a second panel that is provided with stitching or adhesive for modulating the unfurling action of an air bag after its peripheral seam comes out of a cover. For example, the second panel is formed with stitched portions or bonded portions, or tethers spanning the second panel are connected to the peripheral seam of the air bag. Further, only a single layer of a first panel of the air bag is disposed between the gas outlets of an igniter and the vehicle occupants. In operation, the peripheral seam of the air bag, when located within the cover, slides along the inner side wall of the cover against the friction therebetween, so that the first panel is slowly unfurled through an opening in the cover. After the peripheral seam of the air bag is ejected out of the cover, the above-indicated stitching or adhesive provided for the second panel is adapted to modulate the unfurling action of the air bag in the lateral direction and toward the vehicle passenger, so that the air bag can be unfurled at a relatively low rate.
