    • An airbag door is formed integrally with an instrument panel where an outer skin member 10, in which a foam layer 12 is bonded to an outer skin 11, is bonded and laminated to a substrate member 4, and a tear line for performing fracture and deployment when an airbag is in operation is formed at a door substrate member portion of a substrate member 4. An adhesive strength between the foam layer and the above-mentioned door substrate member portion is set as a peel strength of at least 10N/25mm width or more. In the above-mentioned outer skin member 10, an outer skin single body fracture strength is set to 1.4-12.0 MPa, an outer skin single body elongation at break is set to 200-600%, and a peel strength between the foam layer and the outer skin is set to a range of 10-50N/25mm width.
    • 安全气囊门与仪表板一体地形成,其中发泡层12结合到外皮11上的外皮部件10粘接并层压到基底部件4上,并且用于执行断裂和展开的撕裂线 在基板部件4的门基板部件形成有安全气囊的情况下,将泡沫层与上述门基板部件的粘合强度设定为10N / 25mm以上的剥离强度, 更多。 在上述外皮部件10中,外皮单体断裂强度为1.4〜12.0MPa,外皮单体断裂伸长率为200〜600%,发泡层和 外皮设定为10-50N / 25mm宽度的范围。
