Abstract
An arrangement and method is described of forming an air bag deployment opening in an interior trim piece having an vinyl skin overlying a rigid substrate so as to be invisible prior to operation of the air bag system, comprising an energy generating linear cutting element arranged in a door pattern beneath the skin acting to degrade or cut the skin when activated. The element is mounted either in an outwardly facing channel formed in door sections of the substrate or on a separate membrane interposed between the skin and substrate.
