The invention relates to an airbag module for a safety system for vehicle passengers, comprising an airbag, a gas generator (23) and a diffuser (10) with a dome section (11) and at least one retaining section which maintains the airbag in a compressed manner. Said retaining section comprises at least one securing opening in which at least one securing device, in particular a securing bolt, is received. Said securing opening (13) is arranged below the dome section (11).

The present invention provides a gas generator, including: an ignition device chamber arranged at a first end opening of a cylindrical housing; a diffuser portion provided with a gas discharge port and arranged at a second end opening opposite to the first end opening in a longitudinal axial direction of the cylindrical housing; a pressurized gas chamber arranged between the ignition device chamber and the diffuser portion; a first rupturable plate closing the first end opening between the ignition device chamber and the pressurized gas chamber; a second rupturable plate closing the second end opening between the pressurized gas chamber and the diffuser portion; an igniter and a molded article of a gas generating agent being accommodated in the ignition device chamber; a gas which serves as a gas source being charged in the pressurized gas chamber under a high pressure; and an amount A (J/msec) of energy generated per unit time from the molded article of the gas generating agent charged in the ignition device chamber, a cross-sectional area B (cm.sup.2), orthogonal to the longitudinal axial direction of the cylindrical housing, of the pressurized gas chamber at a portion proximate to the ignition device chamber, and a density C (g/cm.sup.3) of the gas charged in the pressurized gas chamber satisfying an energy control factor represented by the following equation (I):

A/BC=320 to 490(I).

The invention relates to an apparatus (10) for fastening a gas generator (11) in an oscillatory manner as a vibration damping mass inside an airbag module. A fastening ring (12) provided for fastening the gas generator (11) has at least one elastic section (14) and at least one reinforcement insert (15) for reinforcing the fastening ring (12) and securing the fastening ring (12) to the gas generator. A surface of the reinforcement insert (15) is made at least in part of plastic.
