The invention relates to a hybrid gas generator () which comprises a compressed gas chamber () and an igniting unit (), wherein the compressed gas chamber () is closed by a first igniter-side bursting membrane () and a second bursting membrane (). According to the invention, a first, rapidly burning-off pyrotechnic agent () and a second pyrotechnic agent () burning off slowly in comparison to the first pyrotechnic agent () are located in the hybrid gas generator (), wherein the second bursting membrane () is openable by positive pressure which can be generated in the compressed gas chamber () and the first pyrotechnic agent () is separated from the second pyrotechnic agent () in such a manner that the positive pressure in the compressed gas chamber () for opening the second bursting membrane () can be generated by the first pyrotechnic agent ().

The invention relates to a hybrid inflator () comprising a combustion chamber () and a pressure gas tank (), wherein in the idle state of the hybrid inflator () an outlet opening () of the pressure gas tank () is closed by a bursting element () which in the case of function of the hybrid inflator () can be destroyed by means of a penetration element (), wherein a mixing chamber () is formed between the pressure gas tank () and the combustion chamber (). In accordance with the invention, between the combustion chamber () and the mixing chamber () at least in portions a partition wall () having a combustion chamber side () and a mixing chamber side () is formed, wherein the partition wall () includes at least one combustion chamber opening () which in the idle state of the hybrid inflator () is closed by a cover () formed on the mixing chamber side () of the partition wall ().
