Air bag door structure of instrument panel
First Claim
1. An air bag door structure for mounting an air bag container containing an air bag, said air bag door structure integrally backed with a door reinforcement member on a rear side of an air bag door opening portion of an instrument panel, said air bag door structure comprising:
- a hinge side break portion, having an inside edge and an outside edge, disposed on a door rotation axis side in the air bag door opening portion of said instrument panel, wherein said hinge side break portion breaks upon a deployment of the air bag from the air bag container;
an opening side break portion, having an inside edge and an outside edge, disposed on a door opening portion side in said air bag door opening portion of said instrument panel;
an instrument panel mount portion having the air bag container mounted thereto, said instrument panel mount portion being unitedly formed adjacent the outside edge of said opening side break portion so as to concentrate stress forces resulting from the deployment of the air bag along said opening side break portion; and
a body portion of said door reinforcement member being integrated with said instrument panel;
a hinge portion serving as a door rotation axis, being formed in said body portion on an inside edge side of said hinge side break portion of said instrument panel; and
a hinge side mount portion having the air bag container mounted thereto, said hinge side mount portion extending from said body portion on an inside edge side of said hinge side break portion of said instrument panel so as to concentrate stress forces resulting from the deployment of the air bag along said hinge side break portion.

Abstract
An air bag door structure is integrally backed with a door reinforcement member in the rear of an air bag door opening portion of an instrument panel. A hinge side break portion of is provided at the door rotation axis side of the instrument panel, and a hinge side mount portion for mounting an air bag container is formed at a hinge portion of the door reinforcement member. An instrument panel mount portion for mounting the air bag container is integrally formed along the outside of an opening side break portion of the instrument panel. Accordingly, stress forces created by the deployment of the air bag are concentrated at the break portions.
