METHOD FOR MANUFACTURING AN AIRBAG COVER WITH A WEAKENING LINE AND AIRBAG COVER WITH A WEAKENING LINE PRACTICED IN SAID CACHE

摘要

The invention relates to a method of manufacturing an airbag cover with a weakening line (10), which comprises a plurality of steps. Firstly, positioning a wire (4), provided with at least one loop (6) and having a shape corresponding to the shape of the line of weakness to be practiced, between a first layer and a second layer of airbag cover to manufacture. The first layer has a thickness that corresponds to a desired residual wall thickness of the airbag cover at the location of the line of weakness. The at least one loop is directed through at least one opening of the second layer. Then, the first layer and the second layer are assembled together. The weakening line is formed in the second layer during the manufacture of the air bag cover by pulling on the at least one loop, so that the thread is detached from the first layer and the second layer and the second layer is cut according to the shape of the wire.
