<p><P>PROBLEM TO BE SOLVED: To provide an automobile interior equipment body for easily ensuring rapidity and stability in lid deployment performance (airbag development performance) when an airbag is operated. <P>SOLUTION: A lid body is provided to allow an airbag to be ejected. The lid body is integrally injection-molded of a hard resin material together with other body parts. In order to demarcate the lid body 12, a tear line (a predicted breakage line) TL is formed with a thick-walled portion and a thin-walled portion alternately formed on the back side thereof. The tear line TL comprises a turning end tear line (a first tear line) 18, a hinge tear line (a third tear line) 20, and a side tear line (a second tear line) 19 to connect both ends of the turning end tear line and the hinge tear line. A low breaking strength part LB is constituted by adjusting the sectional area thereof so that breaking strength at the center of the turning end tear line 18 is lower than that of the other portion of the turning end tear line. <P>COPYRIGHT: (C)2004,JPO</p> |
