At a generally central portion in the longitudinal direction and on both sides in the lateral direction of an airbag door section (20) of an instrument panel (10), a tier section (24) of a H shape when viewed from above is provided. In the airbag door section, projections (28, 30) protrude downward from both sides in the lateral direction of the vehicle, of the central part (24A) of the tier section (24), and these projections (28, 30) are molded integrally with the airbag door section (20). As a result, when the airbag body is developed, the developed airbag body (18) comes into contact with the under faces (28A, 30A) of the projections (28, 30), and thrust the projections (28, 30) upward. Thus, it is possible, even when the airbag door section and the body section of the interior member are molded of the same resin, that the breaking force acting on the fracturing part of the airbag door section can be reduced to a desired level without deteriorating the appearance.

L'invention concerne une section de niveau (24) d'un profilé en H vu du haut, situé dans une partie généralement centrale dans la direction longitudinale et des deux côtés dans la direction latérale d'une section de porte d'airbag (20) sur un tableau de bord (10). Dans la section de porte d'airbag, des saillies (28, 30) se projettent vers le bas à partir des deux côtés dans la direction latérale du véhicule, dans la partie centrale (24A) de la section de niveau (24), et ces saillies (28, 30) sont intégralement moulées avec la section de porte d'airbag (20). Par conséquent, lorsque le corps de l'airbag est déployé, le corps d'airbag déployé (18) entre en contact avec les faces de dessous (28A, 30A) des saillies (28, 30), et pousse les saillies (28, 30) vers le haut. Ainsi, il est possible, même lorsque la section de porte d'airbag et la section de corps de l'élément intérieur sont moulés dans la même résine, de réduire la force de rupture agissant sur la partie de fracturation de la section de porte d'airbag, à un niveau voulu sans altérer l'apparence.
