Abstract
According to the invention, in order to be able to design a gas generator, in particular, for belt tighteners, with a slim housing (1), the electrical coupling is brought about via connection wires (4), pins or cables (4a) which are introduced into the housing (1) via a stopper (5) and are sealed by the latter. The stopper (5) is surrounded sealingly by the housing (1) itself or a holder element (6) sealingly connected to the housing.
Claims11
Gas generator for a safety device for motor vehicles, comprising:
- a housing having predetermined breaking points to allow for a defined break up of the gas generator,
- a propellant charge provided in the housing for generating a pressurized gas for activating the safety device,
- an igniter located in the housing for igniting the propellant charge,
- an electrical connection for electrically connecting the igniter to a control device located outside the gas generator, the electrical connection being guided via a stopper into the housing and sealed thereby, the stopper being surrounded in sealing fashion by the housing itself or by a retaining element connected to the housing in a sealing fashion, and
- a printed circuit board arranged in the interior of the housing as a connecting element between the igniter and the electrical connection.
