Abstract
There is disclosed a pad for use in an air bag device enclosing an air bag which inflates in case of an accident. The device is mounted to mount members disposed around the bag. The pad is shaped like a box, and comprises an upper wall and side walls extending downward from the fringes of the upper wall. The pad is molded integrally with an insert on which a coat layer is formed out of a soft synthetic resin. The coat layer has a thin-walled portion that breaks when the air bag inflates. The thin-walled portion is disposed at a given position on the upper wall. The insert comprises a rectangular tubular base portion made from a synthetic resin and a plurality of flexible nets disposed on opposite sides of the thin-walled portion. The base portion is disposed inside the side walls. The nets are disposed on the upper wall and connected to the top of the base portion. An attachment portion for mounting the pad to the mount members and setting portions for setting the pad in a mold used to mold the coat layer are formed on the base portions.
