Regulation of pressure in automotive airbags

摘要

A valve is provided in an automotive airbag module housing to relieve any excessive pressure in the module housing as may occur during deployment of an airbag. The valve is formed entirely from material in the housing by punching out openings in the housing material. The invention is applicable to airbag inflating devices in which the inflator is enclosed entirely within the module housing and is particularly useful in passenger side airbag inflation devices.
