Abstract

An airbag module cover an airbag module housing. The cover has two electrically conducting foils which are spaced apart opposite each other between a front panel and a back panel. The distance between the foils is guaranteed by nonconducting spacers which are disposed between the foils. A stop member is connected to the back panel. A gas diffuser is disposed inside the airbag module housing. A space is defined between the diffuser and the stop member. A layer of a folded airbag penetrates the space. When pressed, the cover deflects causing the stop member to travel through the space contacting the folded airbag and stopping against the diffuser. A resulting pressure causes the foils to make contact and activate the horn.
