Abstract

A device for inflating an airbag comprising a container for a compressed gas of a sealing device, which closes the container during normal operation and is provided in a gas release nozzle connected to the container in a gas tight manner, and a throttle opening, via which the released gas flows in a throttled manner out of the container via an emission opening and the gas release nozzle, whereby the throttle opening is formed through reshaping of a container wall part.

Claims

1. A device for inflating an airbag comprising a container for a compressed gas and a sealing device that closes the container during normal operation and is opened to release gas to inflate the airbag, a gas throttle is located in a wall of the container, a gas release nozzle provided with a gas release opening is attached to the container arranged around the throttle opening, the sealing device being integral to the gas release nozzle, and a release device fastened to the gas release nozzle for opening the sealing device by moving a release tappet equipped with a conical sealing ring through a guide opening of the gas release nozzle whereby the conical sealing ring of the release tappet seals the guide opening.

2. The device for inflating an airbag according to claim 1 wherein the sealing device is arranged in the gas release nozzle.

3. The device for inflating an airbag according to claim 1 wherein the gas release nozzle is attached to the container by a the gas tight joint.

4. The device for inflating an airbag according to claim 1 wherein the container wall part in which the throttle opening is located is dome-shaped.

5. The device for inflating an airbag according to claim 1 wherein a tube end of a tube used to inflate the airbag is connected to the gas release nozzle in a gas tight manner is aligned with a longitudinal axis of the gas release nozzle.

6. The device for inflating an airbag according to claim 1 wherein a longitudinal axis of the gas release nozzle runs obliquely to an axis of the throttle opening.
