Abstract: PURPOSE: A curtain airbag is provided to prevent damage to a pillar lamp by expanding an air lamp to a gap between a pillar and the pillar lamp when an air cushion is inflated. CONSTITUTION: A curtain airbag comprises a head lining(5), an air cushion(10), and an air lamp(30). The head lining is located on the top of a pillar trim(3). The air cushion is installed in the rear space part of the head lining. When shock is applied to a vehicle, the air cushion is expanded by gas pressure and is outward inflated. The air lamp guides the inflated direction of the air cushion in order to prevent the air cushion from being inflated to a gap between the pillar trim and a pillar(4). When the air cushion is inflated, the air lamp is exposed in order to allow the air lamp to cover the top of the pillar trim.
