A gas generator for a safety device in a vehicle includes a housing and a combustion chamber located inside the housing. A pyrotechnic propellant and at least one filling body are accommodated in the combustion chamber. The filling body is made of a melamine resin foam.

Gas generator

The disclosure relates to a gas generator—for a vehicle safety system, comprising an ignition unit including a holding element, an igniter and a base. The base is formed by one single plastic injection molding such that the igniter is embedded in the base and the base is injection-molded to the holding element. A membrane which hermetically seals an inner first opening of the holding element is provided.

Gas generator particularly for a vehicle safety system

The disclosure relates to a diffusor for a gas generator of an airbag module, comprising a substantially tubular base body with a longitudinal axis, a baffle cap axially connected to the base body at a first end of the diffusor and a connecting device configured at a second end of the diffusor opposite to the first end. At least one outflow opening is formed in an outer wall of the tubular base body such that gas can flow out of an interior of the diffusor substantially in parallel to a longitudinal axis in the direction of the first end and the second end from the diffusor. The baffle cap is free from an outflow opening. The disclosure further relates to a gas generator comprising such a diffusor, as well as an airbag module including such a gas generator. Moreover, a method for manufacturing the diffusor is also proved.

Diffusor for a gas generator, gas generator with such diffusor and manufacturing method for such diffusor

A deflector for a diffusor of a gas generator of an airbag module is disclosed. The deflector comprises a substantially tubular deflector base body and a gas discharge device connected thereto, wherein the gas discharge device has a substantially rectangular base and two outflow regions on opposite sidewalls so that gas can flow substantially in opposite directions along the longitudinal axes of the tubular deflector base body out of the interior of the gas discharge device to the outside.

Deflector for a diffusor of a gas generator

The invention relates to a gas generator (), especially for a vehicle safety system, comprising a sleeve () positioned inside the gas generator () which sleeve has first flow orifices () and encloses an ignition chamber () including first propellant (), wherein a combustion chamber () filled with a second propellant () is connected to the outside of the sleeve (), the combustion chamber being surrounded by a diffusor () located inside the gas generator () and having second flow orifices (), and comprising a baffle plate () which has third flow orifices () and surrounds the diffusor (), wherein the sleeve (), the diffusor () and the baffle plate () are adhesively bonded to each other.

Gas generator, especially for a vehicle safety system

The invention describes an igniter support () for an igniter unit () of a gas generator (), comprising a first holder element () made from a first material and a second holder element () made from a second material different from the first material. The two holder elements () can be positively coupled to each other, especially can be at least partially positively nested. Further, a subassembly (), a gas generator () as well as a method for manufacturing a gas generator () are described.
