Abstract

The airbag of the head-protecting airbag apparatus includes a rear inflatable portion deployed at the interior side of the rear pillar. The rear inflatable portion includes an upper side portion extending rearward from a gas feed passage disposed at the upper periphery of the airbag, a main body disposed below the upper side portion and partitioned from the upper side portion by a partitioning portion, and a branched portion extending downward from the gas feed passage. The main body inflates with inflation gas fed from an inlet opening disposed at the lower end of the branched portion. At least a front lower area of the upper side portion is located below a parting line between a rear pillar garnish and an airbag cover at full inflation of the airbag. The upper side portion and the gas feed passage are folded and housed at exterior side of the folded-up main body and branched portion such that the main body is pushed out toward an interior of the vehicle getting over the upper end of the rear pillar garnish by the upper side portion and the gas feed passage.

Description

technical field [0001] The present invention relates to a head protection airbag device having an airbag for protecting the head of an occupant, and the airbag is deployed and inflated downward from the upper edge side of a window (side window) by flowing inflating gas. Background technique [0002] Conventionally, in the head protection airbag device, the airbag is covered by an airbag cover, and is folded and accommodated on the upper edge side of the window on the vehicle inner side including the portion above the pillar portion. When the inflation gas flows into the airbag, the airbag cover is pushed open to expand and inflate downward from the upper edge side of the window so as to cover the pillar portion and the vehicle inner side of the window. In addition, in the conventional head protection airbag device, in order not to make the expanded airbag intrude into the vehicle outer side of the pillar garnish covering the vehicle interior of the pillar portion, and hinder...
