Air bag mount structure for vehicle
First Claim
1. An air bag mount structure for a vehicle having a front body structure including at least one dash panel and at least one cowl panel for partitioning a passenger compartment from an engine room, the air bag mount structure supporting an air bag unit having an air bag for absorbing a shock against a passenger comprising:
- a pair of hinge pillars, each of said hinge pillars arranged in the front body structure of the vehicle and supporting a door unit through a hinge device,support means for supporting said air bag unit extending in a transverse direction of the vehicle and connected with both of the hinge pillars at opposite ends, andat least one mounting bracket for mounting the air bag unit on the support means, the mounting bracket connecting the air bag unit only to the support means, the support means being not directly connected to any of the dash and cowl panels so that rearward deformation of the dash and cowl panels during a collision is not transmitted to the air bag unit directly.

Abstract
An air bag mount structure for mounting an air bag unit which is disposed behind an instrument panel for absorbing a shock against a passenger seated in a front seat of a vehicle includes a hinge pillar arranged in a front body structure of the vehicle for supporting a door unit through a hinge device. A support device mounts the air bag unit thereon. The support device is mounted on the hinge pillar at one end portion and on either the hinge pillar or a floor panel 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.
