<P>PROBLEM TO BE SOLVED: To prevent appearance from looking unattractive even when the main body of a vehicle interior trim having an airbag door section is made thinner. <P>SOLUTION: An airbag chute 11 has a flange section 17 which is vibration-welded to an area surrounding the airbag door section 9 on the rear surface of a base material 3 (the interior trim body) of an instrument panel 1. Also, the air bag chute 11 is equipped with a frame body 13 in which an air bag device 31 is housed, a flap section 19 which is vibration-welded to the rear surface of the airbag door section 9, and a hinge section 21 which integrally connects the proximal end sides of the frame body 13 and the flap section 19. On the flange section 17 and the flap section 19, a plurality of first ribs 23 which extend by being tilted to the vibrating direction of the vibration-welding, and a plurality of second ribs 25 which extend by being tilted in a manner to become symmetrical with the first ribs 23 to the vibrating direction are formed into a lattice shape in a manner to cross each other. The first and second ribs 23 and 25 are fixed to the rear surface of the base material 3 by welding. <P>COPYRIGHT: (C)2007,JPO&INPIT |
