Abstract: A module assembly for an airbag device for protecting occupants of motor vehicles includes a carrier for the assembly, an inflatable airbag packet, a flexible protective envelope, and a fixing mechanism. The airbag packet is fixed to the carrier. The airbag packet is accommodated in the flexible protective envelope. The protective enveloped can be closed off in a gastight manner. The fixing mechanism fixes the airbag packet to the carrier. The fixing mechanism includes a holding element. The holding element, which includes a securing mechanism provided on the carrier to fix the airbag packet to the carrier, extends along an edge of the airbag packet. The securing mechanism is formed integrally on the carrier and is resiliently pivotable with respect to a lateral section of the carrier. Alternatively, the securing mechanism is fixed on the carrier as a separate assembly.

Abstract: The disclosed airbag comprises an upper airbag layer, a lower airbag layer, and an intermediate layer dividing the interior of the airbag into a first chamber and second chamber. An outlet is provided through which gas from the first chamber is able to enter the second chamber. The outlet is configured such that, according to an amount of gas introduced into the airbag through the inlet aperture, gas selectively fills substantially only the first chamber or both first and second chambers.
