Abstract
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.
