A curtain airbag device includes a gas generator and a curtain airbag configured to be deployed downward along an inner side surface of a vehicle cabin. The curtain airbag includes a front portion configured to be fixed to at least two sections of a pillar of a vehicle such that the front portion is disposed along a direction in which the pillar extends. A virtual equilateral triangle having a line connecting the first and second sections as a first side of the equilateral triangle is formed in the front portion of the curtain airbag. A region surrounded by the sides of the equilateral triangle includes a portion of an inflatable chamber that is configured to be inflated by receiving gas from the gas generator.

Curtain airbag device

An airbag system includes at least an airbag and a gas supply device. The airbag is mounted to an upper part of a sidewall of a vehicle and has a function of protecting an occupant by inflating downwardly into an occupant protection region between the occupant and the sidewall of the vehicle in a car accident such as a side crash or rolling sideways. The gas supply device having a gas generating function supplies inflation gas to the airbag. The airbag has a folded portion and an extending portion. The folded portion is folded in a predetermined folded shape in advance. The extending portion extends downwardly along the folded portion so as to cover a side of the folded portion from an interior side of the vehicle when the airbag is mounted to the vehicle.

Airbag system

A curtain airbag device for holding a vehicle occupant inside a vehicle cabin at a region of the curtain airbag. A front region of the curtain airbag may be provided with non-inflatable portions. Attachment parts may extending from an upper section, a lower section, and an intermediate section of a front edge of the curtain airbag an attach to a front pillar of the vehicle. When the curtain airbag is inflated, high tensions are generated at areas which are rear extensions of the attachment parts, whereby the front region of the curtain airbag forms a hammock-like structure.

A curtain airbag includes an inflatable cell below a non-inflatable portion that resists being bent when the curtain airbag is inflated. The curtain airbag has a non-inflatable portion and a plurality of inflatable cells that are disposed in front of, behind, above, and below the non-inflatable portion. The lower-side inflatable cell is formed in a convex shape that projects downwardly. When the curtain airbag is inflated, a tensile force acting to pull up the lower-side inflatable cell is generated in the non-inflatable portion. However, as the inflatable cell is formed in a convex shape that projects downwardly, the inflatable cell resists being pulled up and is, therefore, prevented from being bent.

A curtain airbag device includes a curtain airbag disposed along an upper side surface of a vehicle facing a cabin in a folded state to be able to expand downwardly along the side surface, and an inflator for inflating the curtain airbag. A guide airbag is arranged to expand substantially at the same time when the curtain airbag is expanded. The guide airbag guides the curtain airbag toward the cabin and/or regulates an expanding direction of the curtain airbag.

Curtain airbag device and vehicle provided with the same

A curtain airbag device and a guiding element that achieve a simplified installation process for attaching a curtain airbag to a vehicle body, and that allow the curtain airbag to be deployed smoothly. When an inflator is activated, a curtain airbag may be deployed downward. A rear portion of the deploying curtain airbag may be guided along a guide rod via a link strap. The curtain airbag may be folded in a zigzag manner along folding lines extending in a horizontal direction. The link strap may protrude from a bottom corner area of the curtain airbag and have a base end which is disposed at a side of the folded curtain airbag proximate a vehicle body.

A curtain airbag device and a guide unit for facilitating assembly of a curtain-guide member and a guide element to a vehicle body. When an inflator is activated, a curtain airbag is led by a protruding piece of a curtain-guide member to be deployed along the cabin-side of a pillar garnish. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap. The link strap starts moving downward along the guide rod when the curtain airbag begins to be deployed. The guide rod and the curtain-guide member are temporarily fixed to each other by a bolt in advance.

Guide unit for guiding curtain airbag and curtain airbag device

A curtain airbag device and a guide unit are provided such that a lower rear portion of a curtain airbag can be deployed smoothly. When an inflator is activated, a curtain airbag is deployed in the downward direction. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap. To fold the curtain airbag, the lower rear portion of the curtain airbag is folded back at an angle along slanted folding lines. Subsequently, the curtain airbag is rolled or folded along lines extending in a horizontal direction of the curtain airbag. This airbag structure allows the lower rear portion of the curtain airbag to be deployed downward and towards the back of the vehicle.

A curtain airbag device and a guide unit achieve a quick and smooth deployment of a curtain airbag. When an inflator is activated, a curtain airbag is deployed downward along an inner side surface of a pillar garnish facing the interior of a vehicle cabin. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap and a ring. Before the airbag is deployed, the ring is supported by an upper portion of the guide rod by a holder. When the airbag is deployed and link strap begins to move downward, the ring is released from the holder and moves along the guide rod.

A curtain airbag device and a guide unit allow for quick deployment of a curtain airbag by smoothly guiding a link strap that connects a curtain airbag and a guide element into the space between a side edge of a pillar garnish and a vehicle member at the early stage of the deployment of the curtain airbag. When an inflator is activated, a curtain airbag is deployed downward along the cabin-side of a pillar garnish. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap. The link strap starts moving downward along the guide rod when the curtain airbag begins to be deployed. At this moment the link strap is guided into the space between the pillar garnish and a weather strip by a guide member.
