Abstract
An invisible cover door for an inflatable passive passenger restraint is provided in an interior trim structure of an automotive vehicle for deployment of an airbag therethrough. The low pressure insert injection molding of the cover door into the interior trim structure, such as an instrument panel or dashboard or door panel structure, produces an invisible cover door with tear propagation lines that are undetectable to a vehicle occupant and that do not "show" or mar or otherwise affect the aesthetic appearance of the outer trim surface of the instrument panel or dashboard. Such invisible doors which require only two tear propagation lines can be provided.
