Abstract

In an embodiment of the present invention, a device for influencing the flow of the gas into a gas bag of an airbag module with an inflating device and a gas bag, wherein at least one component part is provided between the inflating device and the gas bag. The component part is deformable under the pressure of the gas emerging from the inflating device and forms or releases at least one opening in the predetermined direction. The component part has a flap-like section which is defined at least in part by surrounding perforations in the component part, and between the component part and the flap-like section there are overlapping slits between which at least one retaining tab is formed which connects the component part to the flap-like section.
