Abstract

The invention relates to a the gas bag module, comprising a gas bag and a module housing which has a front wall that closes a ring-shaped outlet opening for the gas bag. A centric portion of the front wall is attached radially inwardly of the outlet opening such that, in the region of attachment, the centric portion is prevented from freely moving outwards when the front wall is opened. At least the centric portion of the front wall, which is attached to the module, has such a thickness and elasticity that upon deployment of the gas bag it swivels, without tearing open radially, about the attachment outwards and radially inwards, as seen from the module, and makes folds in order to clear the ring-shaped outlet opening.
