    • The present invention intends to provide an air bag door construction in which the air bag develops smoothly and securely, the skin can be easily produced with small man-hour, and which is excellent in the surface appearance.The skin 50 is formed by a mold 5 including an endless and annular wall 50 provided at a part of a molding surface to be inclined relative to the molding surface. A groove portion 35 of the skin 3 formed by the wall 50 is cut at a bottom portion thereof to separate the skin 3 into a general portion 30 and a door portion 31. The general portion 30 and the door portion 31 are relatively shifted to make both surfaces thereof flush with each other.When the surfaces of the general portion 30 and the door portion 31 are flush by the relative shift, gap between the general portion 30 and the door portion 31 can be narrowed, and gap appeared on the surface can also be narrowed. Also, when the skin is disposed in the mold for foam forming, the skin can position the general portion 30 and the door portion 31 in the desired position easily, and will not scatter a skin chip in the development of the air bag.
    • 本发明旨在提供一种气囊门结构,其中气袋平稳而可靠地发展,能够以小的工时容易地制造皮肤,并且表面外观优异。 皮肤50由包括设置在成型表面的相对于模制表面倾斜的部分的环形壁50的模具5形成。 在其底部切割由壁50形成的皮肤3的槽部分35,以将皮肤3分离成一般部分30和门部分31。 一般部分30和门部分31相对移动,使其两个表面彼此齐平。 当通用部分30和门部分31的表面通过相对移动齐平时,通用部分30和门部分31之间的间隙可以变窄,并且表面上出现的间隙也可能变窄。 此外,当将皮肤设置在用于泡沫形成的模具中时,皮肤可以容易地将通用部分30和门部分31定位在期望的位置,并且不会使皮肤碎片散布在气囊的展开中。
