Abstract: 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 a 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 in the backing layer. Embossing a desired pattern in the leather or covering material with a design in the mold cavity is also disclosed. A method for molding leather covered, resinous articles using a preformed, preshrunk leather piece, which articles optionally have designs, indicia or enhanced leather graining embossed during molding, is also disclosed.
