An airbag includes a bag body and an inlet port section of inflation gas. As a gas receivable region, the bag body includes a front main inflatable region, a rear main inflatable region, a feed path that feeds the inflation gas from the inlet port section to the front and rear main inflatable regions, and a sub inflatable region that absorbs the gas from the front main inflatable region when a pressure of the front main inflatable region soars. A front partitioning region partitions the front main inflatable region from the sub inflatable region. The front partitioning region is disposed in front of a front end of an upper partitioning region in an island-like fashion remote from other uninflatable region so as to provide, at the rear of and there beneath, one each communication passage that provides gas communication between the front main inflatable region and the sub inflatable region.

Airbag for head protection

A head-protecting airbag device includes: an airbag loaded in a vehicle as a completely folded body folded to be storable in the storage portion; and a regulation member, to be arranged near a bent portion in the completely folded body at a time of conveyance. The regulation member is formed of a belt-shaped body having flexibility, and capable of regulating a twist of the completely folded body at the bent portion when the completely folded body is assembled into the vehicle. In a state where a protrusion part is engaged with a periphery of an assembly hole, both front and rear sides of the protrusion part are wrapped together with the completely folded body by a wrapping material. A length dimension of a portion between the assembly holes is set to be a length dimension which disenables one turn of twist in a circumferential direction of the completely folded body.

Head-protecting airbag device

A head-protecting airbag device includes a case which houses an airbag in a folded-up configuration and a mounting bracket which is used to mount an inflator on a vehicle body structure. The case is mounted on a region of the airbag extending from one end of the inflator. The mounting bracket includes an insert region which fits in an assembling opening of the case. The assembling opening includes a receiving region which receives the insert region along an axial direction of the inflator and a limiting plane that is located in a periphery of the receiving region and holds the insert region from rotating in both directions in a circumferential direction of the inflator. The fitting of the insert region and assembling opening suppresses the airbag stored in the case in the folded-up configuration from rotating in a circumferential direction.

A case includes an opening at least at the lower region for receiving an airbag, and an engaging region engageable with a mounting bracket. The mounting bracket includes a mounting section which protrudes out of the case and a joint plate which is formed generally into a plate extending generally along an up and down direction and is disposed at a root region of the mounting section for engagement with the case. The engaging region of the case includes an insert slot which allows the joint plate to slide therein generally in an up and down direction, a retaining pawl which protrudes generally in an inboard-outboard direction and is inserted into a retaining hole of the joint plate and retains the joint plate, and an inboard side pressing surface and an outboard side pressing surface which press the joint plate retained by the retaining pawl on the inboard and outboard sides.

An air bag includes an air bag main body and a guide member. The air bag main body includes an expansion portion that expands with expansion gas flowing from an inflator and a tubular connecting port, which is connected to the inflator by inserting a side of a gas outlet port of the inflator thereinto, to cause the expansion gas to flow into the expansion portion, and is formed of a sheet material with flexibility so as to be able to be folded. The guide member has a shape holding property of maintaining an opening state of the connecting port so as to be able to be attached to the connecting port of the air bag main body and guide the insertion of the inflator into the side of the gas outlet port.

Airbag

A head-protecting airbag device includes an airbag and a plurality of casings, each of which stores a folding completion body of the airbag, wherein: each of the casings has an opening for protruding the airbag; the casings are connected to each other by bendable coupling pieces; the folding completion body is configured to be carried in a state of being stored in one casing of the casings by bending of the coupling pieces; the coupling piece has a curved portion that is disposed in a curved manner by reversing between a base portion and a tip portion; and the curved portion is formed such that a protruding direction from a reference line connecting the base portion and the tip portion of the coupling piece is set in a direction intersecting with a surface along an overlapping direction of a longitudinal direction of the one casing with openings.

An airbag of an airbag device includes a connection port to be joined with an inflator and a flexible reinforcing sheet disposed inside the connection port. The reinforcing sheet includes a first cover region and a second cover region each of which wraps the leading end of the inflator and has an opening for providing gas communication with a main body of the airbag. The first cover region has a double-folded configuration that is doubled on a crease which crosses an axial direction of the inflator while the second cover region has a double-folded configuration that is doubled on a crease extending in parallel to the axial direction of the inflator. The first cover region and second cover region are arranged in such an overlapped fashion that the crease of the first cover region continues to the crease of the second cover region.

Airbag device

A head protecting airbag device includes: an airbag configured to cover a window of a vehicle; a winding band wound around a folded body which is formed by folding the airbag, the winding band including: an attachment portion being pressed and locked to an attachment target portion; a band body wound around the folded body; an engaging claw portion formed at one end of the band body; and an engaging target portion disposed at the other end of the band body; and a pressing portion, having a pressing operation surface configured to press-fit the engaging claw portion into an engaging concave portion, disposed at a claw-side end of the band body, wherein the attachment portion is disposed at a concave-side end of the band body so that the press-fit direction to the attachment target portion at the time of locking is substantially perpendicular to the pressing operation surface.

Head protecting airbag device

A head protection airbag apparatus includes an airbag which is configured so that an attaching portion arranged on an upper edge thereof upon completion of inflation is attached to a body of the vehicle using an attaching clip. The attaching portion includes an attaching hole to which the attaching clip is insertable. The attaching clip includes an attaching leg. The attaching leg includes an insertion shaft portion adapted to be inserted in the locking hole and at least a pair of locking claws. The attaching hole is configured so that, when the attaching leg is inserted through the attaching hole, an peripheral edge portion of the attaching hole is pressed against an outer peripheral surface side on a region of the insertion shaft portion which is located more toward the base portion than the locking claws.

Head protection airbag apparatus

A head-protecting airbag apparatus covers a window so that an occupant's head can be protected. The airbag includes a front window shielding portion with an inclining inflatable portion and a horizontal inflatable portion in the shape of a pipe. The inclining inflatable portion is disposed between an upper guide portion that extends continuously from a portion that partitions an upper edge region of the gas supply passage, and a lower guide portion that extends from a portion that partitions a lower edge region of the gas supply passage. The inclining inflatable portion and the horizontal inflatable portion respectively include an inclining peak portion and a horizontal peak portion formed by ridgelines that swell thickly. The respective width dimensions of the inclining inflatable portion and the horizontal inflatable portion in a flat state are larger than the vertical width dimension of the gas supply passage that is flatly deployed.
