Abstract
Abstract A resin material (16), is fed into the air bag cover cavity of a mold provided with a movable member (13), adapted to advance into the resin filled cavity to form the tear-line groove (13A) into the resin material, thereby obtaining a modular cover (1) provided with a tear-line (1A) having a small thickness and a high degree of strength. The method avoids weakness of the tear line groove, that would otherwise arise from flow of the resin around a fixed mould cavity groove- forming configuration. <IMAGE>

WHAT IS CLAIMED IS: 1. A method of manufacturing a modular cover for an air bag by using a mold formed of a stationary lower die, a movable upper die and a tear-line impressing movable member attached to at least either one of the two dies and movable forward and rearward with respect to a cavity formed between the two dies, which method comprises the steps of: withdrawing the movable member away from the cavity of the mold; supplying a resin material into the cavity of the mold; moving the movable member toward the cavity so that a tear-line is formed on the resin material supplied into the mold; hardening the resin material within the cavity of the mold; and separating the hardened resin material from the mold thereby obtaining the modular cover provided with the tearline.
