In an occupant protection device, an airbag disposed in a region of a lap belt of a seat belt includes a bag body and a conduit connected to an inflator disposed near a lower end of a seat portion of a seat. The airbag is held by the lap belt in a folded state. The conduit is disposed substantially along the lap belt while being held by a conduit holder. The conduit holder is formed of a material having flexibility and higher rigidity than the conduit, is disposed substantially along the conduit, and has both end sides fixed to a seat side and a bag body side, respectively, by a seat-side fixing portion or a bag body-side fixing portion.

Occupant protection device

An occupant protection device includes an airbag mounted on a seat of a vehicle and attached to a belt body of a seat belt in a folded state. The airbag is inflated so as to allow an inflation gas discharged from an inflator to flow into the airbag and protect an occupant seated on the seat while protruding forward. An airbag cover is formed in an elongated shape that can cover an outer periphery of part of the belt body and a folding completion body corresponding to a state where the airbag is folded, and is closed such that at least the belt body is allowed to be inserted therethrough at both ends in the longitudinal direction.

Occupant protection device and airbag cover

An occupant protection device includes a seatbelt having a lap belt portion; an inflator; and an airbag that is provided in the lap belt portion. The airbag includes a main body portion, a conduit portion, and a tether. When inflation is completed the main body portion includes a rear wall portion to which one end portion of the tether is linked, a front wall portion that is disposed in front of the rear wall portion, and to which another end portion of the tether is linked, and an upper wall portion that connects the rear wall portion and the front wall portion above the tether. The main body portion is supported by a supporting body via the tether by the tether catching on and being engaged with the supporting body.

A base fabric for airbag is formed by a hollow weave in which a warp yarn and a weft yarn are woven to provide a bag portion having two woven fabric layers and a closing portion having one woven fabric layer, and includes a positioning hole. The positioning hole is formed by the closing portion on a peripheral edge thereof, and a non-weave portion in which the warp yarn and the weft yarn are not woven in an inner side of the closing portion.

Base fabric for airbag

An airbag package includes a one-piece woven airbag in a folded shape, a plurality of markers that are formed on the airbag, and a plurality of tape members that are bound around the airbag at locations of the markers for keeping the folded shape of the airbag. Each of the markers is composed of a weave structure that is different from that of surroundings in the airbag.

Airbag package

A head protecting airbag device is adapted to be mounted on a vehicle provided with an assist grip that is mounted on an upper edge of a window by front and rear attachment portions. An airbag includes a gas inflow portion which is inflatable with an inflation gas and a non-inflow portion which admits no inflation gas. The gas inflow portion includes a shielding portion which covers an area of the window below the assist grip. The non-inflow portion includes a thickness regulating portion which regulates the thickness of the shielding portion when the airbag is inflated. In the shielding portion, the thickness regulating portion is disposed on a front upper portion of the shielding portion below the front attachment portion of the assist grip, and is not disposed below the rear attachment portion of the assist grip.

Head protecting airbag device

An airbag includes an annular attachment portion having an opening portion through which a bracket can be inserted and which is open in a substantially square shape. A case includes a protective ring portion having an opening through which the bracket can be inserted and which protects the annular attachment portion. The protective ring portion includes a corner cover portion that covers areas of front and rear corner portions on an upper edge side of an inner peripheral edge of the opening portion.

A head protection airbag device includes: an airbag configured to cover a window of a vehicle; and a synthetic resin case configured to store a folding completed body of the airbag. The case includes a case body, and a pressing piece formed to partially protrude downward from an upper edge side of the case body and formed to cover a vehicle inner side of the folding completed body. The pressing piece has a band-like outer shape having a width direction substantially along a front and rear direction, and is configured to be able to press the folding completed body toward the case body so that the pressing piece can be bent with respect to the case body and the pressing piece can maintain a folded shape of the folding completed body, the pressing piece formed substantially along a vehicle interior surface of the folding completed body.

Head protection airbag device

A head protection airbag device includes: an airbag formed so as to cover a window of a vehicle; and a case for storing a folded body of the airbag. The airbag has an engaging hole through which an engaging protrusion passes. The case includes the engaging protrusion. A portion constituting a peripheral edge of the engaging hole has recessed sections recessed from an upper edge of the airbag in front of and behind the engaging hole so as to have a tab-shaped portion. In a state in which the airbag is flatly developed, an upper edge of the tab-shaped portion that has the engaging hole is disposed nearly on a same line as an upper edge of a general section of the airbag which is adjacent to the tab-shaped portion.
