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: 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.

Abstract: A curtain airbag device which allows quick deployment of a 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 curtain airbag include first vertical chamber extending from the upper end to the lower end of the curtain airbag along the guide rod and having the maximum horizontal sectional area when being inflated. An angle defined by a centerline in the first vertical chamber and a vertical line is within a range of ±20°.

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 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 acuvated, 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.
