A head portion protection airbag device includes: an airbag, formed into a folded body being folded such that a lower edge side in an unfolded state approaches an upper edge side, wrapped with an unfoldment preventing tape material and attached to the upper edge side of the window, assembled with a twisting restriction member, which is configured to prevent twisting of the folded body, on an upper edge side of the airbag, and attached to the upper edge side of the window as a bag attachment body. A plurality of attachment piece portions, which are attached to a body side of the vehicle, are arranged side by side on the upper edge side of the airbag. The bag attachment body is wrapped with the tape material in a state where the twisting restriction member is assembled to the upper edge side of the airbag in the folded body.

Head portion protection airbag device

Ahead protection airbag device includes an airbag. The airbag includes: a hag main body; and an attachment member configured to attach the bag main body to a predetermined attachment part. The attachment member includes: an attachment substrate; a neck part protruding from the attachment substrate; and an engaging head part arranged with being bulged at a tip end of the neck part. The bag main body has an insertion hole in which the neck part is inserted so as to enable the engaging head part to protrude from an outer surface-side of a folded body of the bag main body. The attachment substrate is arranged at a backside of a peripheral edge of the insertion hole so that the attachment member is attached to the bag main body.

Head protection airbag device

A head-protecting airbag apparatus includes an inflated airbag with a rear inflatable portion covering the vicinity of a rear window of a vehicle, and a gas supply passage that inflates the rear portion. The rear inflatable portion includes a main body portion and an inlet inflatable portion, with a belt-shaped closing portion that partitions the two. The upper communication port and the lower communication port of the belt-shaped closing portion allow the inflation gas to flow from the inlet inflatable portion to the inflatable main body. In both communication ports, the opening area of the lower communication port is larger than the opening area of the upper communication port so that the airbag inflates via the lower communication port upon normal inflation of the airbag, and then inflates via the upper communication port upon abnormal inflation when the lower communication port is obstructed.

Head-protecting airbag apparatus

An airbag apparatus includes an airbag that has a first portion and a second portion. The airbag is folded such that the first portion approaches the second portion. The folded airbag has an elongated shape extending along a first direction. An inletis formed in the airbag. By receiving the supply of gas through the inlet, the folded airbagis inflated while being deployed in a second direction perpendicular to the first direction, such that the first portion moves away from the second portion. The inletis arranged in a part of the folded airbagthat is located in a trailing side in the second direction. A first attachment portionis provided in the same part of the folded airbag. A second attachment portionis provided in each of the ends of the folded airbag 5. The folded airbagis installed in a ceiling of a vehicleby means of the first attachment portionand the second attachment portions. When the airbagis being deployed and inflated, the second attachment portionsfunction to apply an outward tension along the first direction to the airbag

Airbag apparatus

An airbaghas a plurality of vertical inflatable cellstoeach serving as an inflatable portion and non-inflatable portions, each of which is arranged between a corresponding adjacent pair of the vertical inflatable cellstoand formed by a fabric sheetB. The vertical inflatable cellstoare deployed and inflated by inflation gas at positions beside corresponding headrestsL,R of the rearmost seat. In contrast, the non-inflatable portionsdeploy behind the headrestsL,R without inflating. The vertical inflatable cellstoinclude vertical inflatable cellslocated at the center of the direction of the width of the vehicle and side vertical inflatable cellsarranged at both sides of the direction of the width of the vehicle. A slitand a slit, each serving as a displacement permitting portion that permits outward displacement of the corresponding side vertical inflatable cellin the direction of the width of the vehicle, are defined in the non-inflatable portionand the non-inflatable portion, respectively. The slitseach extend from a distal edgeof the corresponding non-inflatable portiontoward a proximal portionA of the airbag
