Abstract: The invention relates to an airbag module, comprising a pot-shaped module housing that has a front wall that can be opened and a circumferential wall projecting from a rear side. The airbag module further comprises a baseplate that is attached to the circumferential wall by at least one snap-action hook that is able to latch into an opening. An unlatching protection is provided that reduces a cross-section of the opening after a latching procedure in such a way that unlatching is prevented.

Abstract: An initiator (40) for actuating an inflation fluid source (34) for an inflatable vehicle occupant protection device (36) comprises a plurality of electrically energizable microelectromechanical system (MEMS) devices (120-126). In one embodiment, the MEMS devices (120-126) are associated in a one to one relationship with chambers (75-78) containing ignitable material (130). Each one of the MEMS devices (120-126), when energized, generates combustion products, including heat, for igniting the associated ignitable material (130). At least one terminal pin (44-46) is electrically connected with the plurality of MEMS devices (120-126) for receiving an electric signal for energizing at least one of the MEMS devices.
