description The device has an exhaust opening with a size that is variable based on a signal that is conducted outward. The exhaust opening is provided at a gas bag (2) and/or in an assembly that is connected with the opening. A piezoelectric operable unit is provided for varying the size of the exhaust opening (13). A piezo electric servo valve (18) is provided as the piezoelectric operable unit, where the servo valve is defined for opening of a larger valve. The larger valve exhibits a plane closure part (14) that covers the exhaust opening, where the closure part is larger than the exhaust opening. Die Erfindung betrifft eine Vorrichtung zur Entlüftung eines Gassacks in einem mit einem Gasgenerator verbundenen Airbagmodul mit mindestens einer Ausströmöffnung, deren Größe in Abhängigkeit von einem von außen zugeführten Signal veränderbar ist. Um eine Entlüftung eines Gassacks unter Berücksichtigung äußerer Faktoren, wie z. B. Insassenfaktoren zu schaffen, wobei die Entlüftung einen geringeren Aufwand als die Vorrichtungen des Standes der Technik erfordern, ist erfindungsgemäß für die Größenänderung der Ausströmöffnung (13) mindestens ein piezoelektrisch betätigbares Element (18) vorgesehen.
