Abstract: A gas densimeter for monitoring a pressure or density of a gas in a gas chamber with a housing having a first housing chamber and a measuring chamber, a first coupling, via which the measuring chamber can be connected to the gas chamber, at least one reference bellows, which is connected directly or indirectly in particular to a transmission element, and at least one transmitting and/or monitoring unit, which is or can be operatively connected directly or indirectly to the transmission element. In this regard, the measuring chamber has a gas-permeable connection to the gas chamber via the first coupling and the reference bellows forms a reference chamber filled with a constant amount of a reference gas. A surface section covering the reference chamber is provided or reachable at least partially within the first housing chamber or measuring chamber as a measuring surface for the gas from the gas chamber.

Abstract: A gas hag arrangement for a vehicle occupant restraint system comprises an inflatable gas hag, wherein the gas bag includes at least one vent device for venting gas from the gas bag, wherein the vent device in a first condition has a first outflow cross-section and in a second condition a second outflow cross-section; as well as a release mechanism which initially fixes the vent device and which releases the same after activation. The release mechanism includes an element to be filled with gas, with which the vent device is connected such that before filling of the tillable element it is fixed at the same and during filling of the fillable element is detached from the same, wherein the vent device is directly or indirectly connected with the tillable element via a releasable connection which will tear during filling of the fillable element and release the vent device.
