  • Hybrid gas generator, method for operating a hybrid gas generator, airbag module and vehicle safety system
    Patent number: 11766988
    Abstract: The invention relates to a hybrid gas generator (10) which comprises a compressed gas chamber (20) and an igniting unit (30), wherein the compressed gas chamber (20) is closed by a first igniter-side bursting membrane (21) and a second bursting membrane (22). According to the invention, a first, rapidly burning-off pyrotechnic agent (51) and a second pyrotechnic agent (52) burning off slowly in comparison to the first pyrotechnic agent (51) are located in the hybrid gas generator (10), wherein the second bursting membrane (22) is openable by positive pressure which can be generated in the compressed gas chamber (20) and the first pyrotechnic agent (51) is separated from the second pyrotechnic agent (52) in such a manner that the positive pressure in the compressed gas chamber (20) for opening the second bursting membrane (22) can be generated by the first pyrotechnic agent (51).

  • Propellant cage for an inflator, inflator comprising such propellant cage operating method and method of guiding a shock wave of an inflator
    Patent number: 11077820
    Abstract: The invention relates to a propellant cage (10) for an inflator, especially for a tubular inflator of an airbag module, comprising a substantially tubular base (11) which forms, on the one hand, a gas inlet opening (12a) and, on the other hand, a gas outlet opening (12b) along its longitudinal axis (L), wherein at least one lateral gas flow opening (13) is configured in a circumferential wall (12) of the base (11), wherein the base (11) includes a radially outwardly extending collar (11c) having at least one frontal gas flow opening (14) in the area of the gas flow opening (12c).
