A passenger air bag (PAB) device comprising:
- a crash pad including a cutting groove recessed at a predetermined depth in an inner side surface of the crash pad;
- a PAB chute including an air bag door welded to the inner side surface of the crash pad in a shape covering the cutting groove, the air bag door including a protruding portion, the air bag door being welded to the inner side of the crash pad, inside a space forming the cutting groove;
- and
- an air bag, the PAB chute being positioned between the air bag and the crash pad,
- wherein the protruding portion protrudes from a surface of the air bag door toward the crash pad, and
- wherein, when the air bag is deployed, the air bag is inflated to break one or more welds between the air bag door and the inner side of the crash pad, and force the protruding portion against the cutting groove of the crash pad to form a crack in the crash pad opposite the cutting groove, before the door breaks open the crash pad to allow the air bag to extend out of the crash pad.
