A gas generator () comprises a housing () in which a conical combustion chamber screen () terminates the combustion chamber (). On the front side, the combustion chamber screen () is closed by an end cap () to which a filter element () is connected which has one or more axially projecting centering extensions () on the edge of the filter bottom ().

Gas generator

The disclosure relates to a gas generator for a vehicle safety system, comprising an ignition unit, a propellant configured in a combustion chamber in a form of a propellant bed extending along a longitudinal axis of the gas generator. A sleeve having an axial opening protrudes into the propellant bed such that it surrounds the ignition unit at least partially and portions of the propellant are stored inside and outside the sleeve.

Gas generator for vehicle safety system, airbag module and vehicle safety system as well as method for operating a gas generator

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 ().

Hybrid gas generator, method for operating a hybrid gas generator, airbag module and vehicle safety system

The disclosure relates to a gas generator for a vehicle safety system, comprising a first ignition stage, and a second second ignition stage. The first ignition stage comprises a cup-shaped diffuser with a diffuser base and an adjacent diffuser sidewall (). The first ignition stage, the diffuser and the second ignition stage are arranged along an axial longitudinal axis of the gas generator and the diffuser is positioned between the first and second ignition stages such that the second ignition stage is fastened on an outer area of the diffuser.

Gas generator for vehicle safety system, airbag module and vehicle safety system

The invention relates to an overigniting protection device () for a multi-stage gas generator (), comprising a combustion chamber limiting element () for limiting a combustion chamber () of a second ignition stage () of the gas generator () as well as an overigniting protection element () which is arranged on a side of the combustion chamber limiting element () remote from the combustion chamber (), wherein the overigniting protection element () covers the side of the combustion chamber limiting element () remote from the combustion chamber (), wherein the overigniting protection element () is tightly connected to the combustion chamber limiting element () via a mounting portion () and wherein the overigniting protection element () is substantially plate-shaped or completely covers the side of the combustion chamber limiting element () remote from the combustion chamber (). Furthermore, the invention relates to a second ignition stage () of a multi-stage gas generator, a gas generator () and an airbag module comprising a gas generator ().

Overigniting protection device, second ignition stage, gas generator and airbag module

The invention relates to an inflator () comprising an ignition unit () having an igniter (), a chamber () arranged axially downstream of the ignition unit () and a diffuser chamber () arranged axially downstream of the chamber () which is comprised by a diffuser (), wherein a combustion chamber screen () having an igniter-side end () and a diffuser-side end () is disposed in the chamber (), the combustion chamber screen () being tapered, especially conically, in the longitudinal direction (L) of the inflator () from the igniter () toward the diffuser ().

Gas generator, airbag module and motor vehicle safety system

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 ().

Hybrid inflator, method of operating a hybrid inflator, airbag module and vehicle safety system

The invention relates to a combustion chamber () comprising an opening device for a compressed gas tank () of a hybrid inflator (), wherein the combustion chamber () comprises a sleeve-type combustion chamber sidewall () confining a combustion chamber interior () and a combustion chamber bottom (), wherein the opening device is arranged on a surface () of the combustion chamber bottom () facing away from the combustion chamber interior () and faces away from the combustion chamber interior (). In accordance with the invention, the combustion chamber bottom () is tightly connected to the combustion chamber sidewall () so that in the case of operation the combustion chamber bottom () is bendable.
