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.
