Method of manufacturing a cover component of airbag system, airbag system, and vehicle interior trim |
摘要 |
To provide a cover component having a tear line formed of a recessed line and hollows with a specified depth and being easy to manufacture, the cover component (1) is formed of a synthetic resin by injection molding. The cover component (1) has a tear line (2) for partially opening the cover component (1) by the pressure of an airbag when the airbag inflates. The tear line (2) includes a recessed line (2a) and hollows (2b) arranged in the recessed line (2a) at intervals. The recessed line (2a) is formed by providing a raised line on the core surface of a die when the cover component (1) is formed with the die. The hollows (2b) are bored by irradiation with a laser beam. <IMAGE> |
