Abstract

A hybrid gas generator for use in an occupant restraint system for vehicles comprises a pressure chamber (10), a combustion chamber (14) delimited by a combustion chamber wall (16) and containing a pyrotechnic charge (12), and a passage element (20) arranged between the pyrotechnic charge and the pressure chamber. For a form-fitting securing of the passage element (20) on the combustion chamber wall (16), the passage element (20) and the combustion chamber wall (16) have at least in part a conical shape. On the side facing the pyrotechnic charge (12), the passage element (20) has a collar (38) which acts as a spacer between the passage element (20) and the pyrotechnic charge (12).
