<p><P>PROBLEM TO BE SOLVED: To provide an installation structure of a curtain airbag and an airbag device where the curtain airbag expands quickly downward without increasing the output of an inflater. <P>SOLUTION: The curtain airbag 1 is disposed along a roof side rail 2R of a motor vehicle in the state of being folded into an elongated shape extending in the fore-and-aft direction. A folded body of the curtain airbag 1 is covered by a roof lining 5 attached to the ceiling portion of the vehicle. A space S for allowing passage of the curtain airbag 1 in the course of inflation is formed between an end edge 5a of the roof lining 5 and a cabin side surface 2f of the roof side rail 2R. The space S is closed by a lip portion 10b projecting toward the cabin from a weather strip 10 attached to the roof side rail 2R. The lip portion 10b is provided with a deformation inducing portion (recessed groove) 10c for inducing bending deformation thereof so that the lip portion 10b leaves the space S as the curtain airbag 1 which is in the course of inflation passes through the space S. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
