To cleave an airbag door and break a base material so that a skin member is ruptured in one direction at the time of deployment of an airbag.SOLUTION: An airbag door structure comprises: a base material in which a skin member is arranged on a front side; and a door member formed like a plate and arranged on a reverse side of the base material. The door member includes: a frame part formed in a cylindrical shape; and a first door part and a second door part connected respectively to one side of the frame part, and partitioned by interposing a prescribed division line that should be cleaved at the time of deployment of the air bag. The base material has a tier part formed on the inside of the frame beyond the frame part of the door member on the reverse surface of the base material. The tier part has: a frame following section which is formed along the frame part of the door member; a division line section formed along the prescribed division line; and a pair of protrusions which respectively protrude in a frame outward direction beyond the frame following section, and which are formed so that foot ends on both sides are linked to the frame following section and so that an apex is linked to an end of the division line section.SELECTED DRAWING: Figure 1

    【課題】エアバッグ展開時に表皮部材を一方向に破断させるようにエアバッグドアを開裂させベース基材を破断させること。【解決手段】エアバッグドア構造は、表側に表皮部材が配置されるベース基材と、ベース基材の裏側に配置される板状に形成されたドア部材と、からなる。ドア部材は、筒状に形成された枠部と、それぞれ枠部の一辺に接続され、エアバッグ展開時に開裂すべき所定分割線を挟んで区画された第一ドア部及び第二ドア部と、を有する。ベース基材は、ベース基材の裏面におけるドア部材の枠部よりも枠内側に形成されたティア部を有する。ティア部は、ドア部材の枠部に沿って形成される枠沿線部と、所定分割線に沿って形成される分割線部と、それぞれ、枠沿線部よりも枠外方向に向けて突出すると共に、両側の裾野端が枠沿線部に連結しかつ頂点が分割線部の端部に連結するように形成された一対の突出部と、を有する。【選択図】図1
