Vehicle occupant restraint device
First Claim
1. A vehicle occupant restraint device having a gas bag module (12), comprisinga gas generator (14) for inflating a gas bag (16),at least one discharge opening (20) that is formed in a rigid component of said gas bag module (12), through which gas that is produced by said gas generator (14) and conveyed into said gas bag (16) can be discharged, andat least one closing device (22) for said discharge opening (20), which has an adjusting device and a plurality of covers of different pressure sensitivities,a specific one of said covers being placed in front of said discharge opening (20) by said adjusting device even before said gas bag module (12) is activated, so as to close said discharge opening (20) 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 said discharge opening through bursting.

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.
