Abstract

A curtain airbag for a vehicle includes an airbag cushion, an end of which is mounted to an inner panel inside the vehicle, and having a folded portion above the end; and an inflator for deploying the airbag cushion, mounted near the end of the airbag cushion. The folded portion may be wound in a spiral. The inflator may be mounted to a center pillar of the pillar trim, and extend toward the inside of the vehicle. The deployment of the airbag cushion is guided by the inflator.
