ABSTRACT:
Pipe-like air duct is formed of hard aluminum foil. Concaves and convexes give flexibility to the air duct. For the air duct, kraft paper is wound on both surfaces of the aluminum foil. This air duct is disposed between an outer panel and an inner panel of vehicle body along the panels, laid to the rear seat of the vehicle, and connected to a blow-off port for the rear seat. In a collision of the vehicle, the air duct is subjected to plastic deformation, by which the shock energy caused by an external force is absorbed.
