Method for manufacturing a cover cap for a gas bag restraint module and cover cap

摘要

A method for manufacturing a cover cap for a gas bag restraint module, which cover cap tears open for deployment of a gas bag, contains the step of treating the cap at least region-wise physically and/or chemically such that its material in a treated region has a lower strength than in an untreated state. The treated region is a predetermined tear-open region for allowing the gas bag to unfold. A cover cap made of plastic for a gas bag restraint module has a predetermined tear region. The cap has a higher brittleness at said tear region than in a remainder of said cap.
