Gas generator

A device for producing a gas generator for an airbag device for a motor vehicle, comprising:

• a pressure chamber configured for filling with gas and configured to receive a housing of the gas generator, the housing being filled with gas via an opening of the housing so that gas introduced into the pressure chamber can enter the housing through the opening;
• an element displaceable in a first direction from a first position to a second position, the element configured in the second position to press a closure of the gas generator arranged in the pressure chamber in the first direction against the housing filled with gas to close the opening, the element comprising a first electrode configured to be electrically connected to the closure in the second position, the closure being formed by a base of the housing.
• a second electrode arranged at least partially in the pressure chamber and configured for electrically connecting with the housing,
• wherein the element is configured to press the closure against the housing when in the second position in such a manner that the closure outside the housing covers the opening formed by the absence of the base, and
• wherein the second electrode comprises a body having a recess configured to receive an end portion of the housing, the body located in the pressure chamber at a distance from the base, or wherein the second electrode is displaceably mounted on the pressure chamber.

A gas generator for inflating an airbag with gas, comprising:

• a housing;
• an opening of the housing configured to fill the housing with gas during production of the gas generator;
• and
• a closure for closing the opening to form a gas-tight accumulator with the housing of the gas generator to store the gas contained therein,
• wherein the opening is formed by an absence of a base of the housing, and wherein the closure is configured as the housing base and covers the opening outside the housing.
