Abstract
The invention relates to a hybrid inflator () including a burst cap () including a bottom () and a sleeve-like side wall (), the bottom () and the side wall () delimiting an igniter compartment (), and the burst cap () in the idle mode being pressurized on the outer peripheral side with compressed gas having a filling pressure (PF) which at a functional maximum temperature of the hybrid inflator () has a maximum filling pressure (PFmax), and wherein the burst cap () can be destroyed by an igniter compartment side bursting pressure in the case of operation. In accordance with the invention, a transitional portion () is formed from the side wall () of the burst cap () to the bottom () so that the igniter compartment side bursting pressure required to destroy the burst cap () is lower than the sum of the maximum filling pressure (PFmax) and the filling pressure (PF). The invention further relates to a burst cap, an airbag module, a vehicle safety system as well as a method of manufacturing a burst cap.
