ション２が設けられる必要域に設けである。For the purpose of protecting occupants in the event of an automobile collision, an air cushion device is provided in an instrument panel, etc., and an air cushion cover is also provided to prevent this device from being directly visible to the occupant. The air cushion cover 3 surrounding the air silane device 2 is made of, for example, a vacuum-formed vinyl chloride sheet 4 and a foamed urethane resin 5, as shown in FIG. Moreover, the air cushion device 2 consists of a combination of a gas generator 116 and a folded cushion 7. Further, the front part of the urethane resin 5 is thin or has a notch 5' as shown in the figure, and the skin sheet 4 corresponding to this part has a knife-cut notch 4' as shown in FIG. It is provided. This knot fa I is for ensuring that the air cushion cover 3 is divided and opened at a set position, and is provided in the necessary area where the air cushion 2 is provided.

きたりして、外観を悪化する場合があった。However, in this conventional method for manufacturing air cushion covers for automobiles, the skin of the air cushion cover is reduced to about 0.
A vinyl chloride sheet mixed with 8 ms ABO resin was molded using a vacuum forming method to form the notch of target 041 above. Since the notch 4' was provided on the seat 4 by one hand processing after foaming the urethane resin, the depth of the notch 4' was not constant, and even if the air cushion cover 3 received the expansion force of the cushion 7, it would not open. Otherwise, cracks may occur in areas other than the notch 4' and the sheet may scatter.Also, unevenness or whitening may occur on the surface of the sheet 4 near the notch 4'. There were cases where the appearance deteriorated.

られるなどの利点が得られる。By integrally providing a foamed resin layer in which the portion corresponding to the notch has a thin wall or a notch, manual post-processing for forming the notch is no longer necessary, and productivity is dramatically improved. Furthermore, since the depth of the notch can be made constant for all molded products, when the cushion is inflated, the air cushion cover including the outer skin of the cushion is reliably opened, thereby safely protecting the human body in the event of an automobile collision. moreover,
There is no fear of cracks appearing in areas other than the nops as in the conventional method, and there are advantages such as a smooth surface between the epidermis surfaces and a visual sensation of concentration.
