Breaking with the door

摘要

PPROBLEM TO BE SOLVED: To prevent a protrusion in an opening rim of an airbag insertion opening formed in a base material from being detached from the base material at the time of opening of door panels. PSOLUTION: In a portion sandwiched between designed branching-break-lines 24B, 24B of a designed door-break-line 24, a protrusion 18 is formed which protrudes inward from the opening rim of the airbag insertion opening formed in the base material 12 by opening the door panels 20, 22. An attachment support body 32 welded to a periphery of the airbag insertion opening 16 in the base material 12 includes a welded part 42 at a region located on the rear side of the protrusion 18. The protrusion 18 is welded to the welded part 42 of the attachment support body 32 so as to be supported by the attachment support body 32. PCOPYRIGHT: (C)2010,JPO&INPIT
