Abstract: A curtain airbag device and a guide unit to allow quick deployment of the curtain airbag are provided. When an inflator is activated, a curtain airbag is deployed downward. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap. The curtain airbag is provided with a first vertical chamber extending along the guide rod from the upper edge to the lower edge of the curtain airbag. An opening area A of an upper portion of the first vertical chamber is equal to or greater than an opening area B of a gas-entrance portion for a vertical chamber and a bag chamber, which are adjacent to the first vertical chamber.

Abstract: A curtain airbag device substantially prevents warping in the rear portion along the lower edge of the curtain airbag during deployment. As inflation occurs the curtain airbag is deployed downwardly. Gas is introduced into an envelope-shaped cell at a rear portion along the lower edge of the curtain airbag. The internal pressure of the envelope-shaped cell rapidly increases because the envelope-shaped cell has a closed end. The envelope-shaped cell becomes highly rigid and extends along the lower edge of the curtain airbag. Thus, warping is substantially prevented. In addition, a tab is positioned at the rear end of the upper edge of the curtain airbag. The area of the rear end portion of the curtain airbag which overhangs behind the tab is extremely small.

Abstract: 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.

Abstract: 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.

Abstract: A curtain airbag device maintains an elevated internal pressure of a curtain airbag for many hours. When an inflator is activated, a curtain airbag is deployed downward along an inner side surface of a vehicle cabin. During the deployment, a duct of the inflator is inserted into a gas inlet of the curtain airbag and is clamped with a clamp such as a band. Elastic adhesives are disposed on grooves in the inner surface of the gas inlet along the ends of a linear connected portion. As a result, the likelihood of gas leakage from the space between the inner surface of the gas inlet and the outer circumference of the duct is reduced.

Abstract: 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.

Abstract: An airbag apparatus for suppressing the movement of an occupant body toward the vehicle outside.
