Abstract
Abstract A pad for an air bag device including an upper wall portion which has an openable portion which, upon expansion of the air bag, is separated from a side wall portion of the pad, leaving a hinge portion, and is angularly movable about that pivot axis so as to be openable. The openable portion is constituted by a net insert of a net-like configuration and a covering layer of a soft material covering the net insert. The net insert has a slit which is formed in one edge portion thereof remote from the hinge portion and extends toward the hinge portion. With this construction, even if part of the pad is curved, the net insert can be set in a corresponding injection mold without generating wrinkles in the net insert, and the molding can be performed in such a manner that the openable portion has a good appearance.
