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 ().
