Skin and manufacturing method thereof, manufacturing method of skin for air bag door and air bag door

Abstract

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 skinis formed by a moldincluding an endless and annular wallprovided at a part of a molding surface to be inclined relative to the molding surface. A groove portionof the skinformed by the wallis cut at a bottom portion thereof to separate the skininto a general portionand a door portion. The general portionand the door portionare relatively shifted to make both surfaces thereof flush with each other. When the surfaces of the general portionand the door portionare flush by the relative shift, gap between the general portionand the door portioncan 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 portionand the door portionin the desired position easily, and will not scatter a skin chip in the development of the air bag.
