초록 ▼

A molded air bag cover for vehicle supplemental occupant restraint systems includes a resinous plastic top wall having a leather or other covering layer bonded thereto and a securing member for attaching the cover to the vehicle. A frangible tear pattern in the covered top wall allows separation for air bag deployment. The tear pattern has a reduced thickness provided by an indented tear seam in the leather or other covering inner surface and an aligned groove in the resinous top wall. A method for making air bag covers includes enclosing leather or other covering material in a mold, advancing a projection on a mold portion against the covering material to form a tear seam, and injecting moldable material behind the covering material to form a backing layer bonded to the material while forming an aligned groove. Embossing a desired pattern in the leather or covering material with a design in the mold cavity is also disclosed. An article and method for molding leather covered, resinous articles having designs, indicia or enhanced leather graining embossed during molding are also disclosed.
