Abstract

Abstract A pad for an air bag apparatus is provided which assures that a part of the pad between a breakage portion and a side wall portion is not scattered away in pieces when the air bag expands. The pad includes an upper wall portion and side wall portions extending downward from the periphery of the upper wall portion. Cover portions adapted to be opened upon breakage of a breakage portion at the time of expansion of the air bag are formed over the upper wall portion. A predetermined number of vertically extending triangular plate-shaped ribs are integrally molded with the upper wall portion and the side wall portions along the periphery of the breakage portion and extend from the side wall portions to the breakage portion.
