<P>PROBLEM TO BE SOLVED: To provide vehicle ceiling structure capable of expanding an air bag when operating the air bag, while sufficiently reinforcing rigidity of formed ceiling when fitting the formed ceiling to a vehicle ceiling part. <P>SOLUTION: When an upward load is applied to a reinforcing block group 30, both of reinforcing block members 32 push each other to seal a clearance between the reinforcing block members 32, and support the upward load through the formed ceiling 12 to restrict deformation of the formed ceiling 12. When operating the air bag, the clearance between the reinforcing block members 32 is forcibly opened, and the reinforcing block group 30 is displaced downward with the formed ceiling 12, and the formed ceiling 12 is deformed in a winding direction (an arrow A direction), and the air bag 28 is expanded into a cabin 100. <P>COPYRIGHT: (C)2007,JPO&INPIT |
