Abstract
Abstract An air bag mount structure for mounting an air bag unit (34) which is disposed behind an instrument panel for absorbing a shock against a passenger seated in a front seat of a vehicle comprising hinge pillar (11) arranged in a front body structure of the vehicle for supporting a door unit through a hinge device, support device (26) for mounting the air bag unit thereon. The support device is mounted on the hinge pillar (11) at one end portion and on either the hinge pillar or a floor panel (28) at the other end. Stability can be improved in supporting the air bag unit so that a reliability of the air bag system can be obtained in operation.
