Abstract
A vehicle occupant restraint device having a gas bag module includes a gas generator for inflating a gas bag, at least one discharge opening that is formed in a rigid component of the gas bag module, through which gas that is produced by the gas generator and conveyed into the gas bag can be discharged, and at least one closing device for the discharge opening. The closing device has an adjusting device and a plurality of covers of different pressure sensitivities. A specific one of said covers is placed in front of the discharge opening by the adjusting device even before the gas bag module is activated, so as to close the discharge opening until a pre-established gas bag interior pressure is reached that is associated with the specific cover, and, when this interior pressure is exceeded, to at least partially release the discharge opening through bursting.
