Airbag module
First Claim
1. Air bag module having a gas generator, which upon a trigger signal instantaneously conducts gas into an air bag (10) made of substantially air-impermeable material, which has an air outlet opening (40) at the end of a tube-shaped mouthpiece (50) through which the gas flows out of the air bag after a dwell time in the air bag (10), the tube-shaped mouthpiece being turned into the air bag when the air bag is in a non-filled condition, wherein the effective opening diameter of the air outlet opening (40) is opened in a time-delay manner after activation of the module, the effective opening diameter of the air outlet opening being opened in such a time-delay manner that the gas pressure in the interior of the air bag remains substantially constant for a time period of up to 50 ms.

Abstract
An air bag module is described which has a gas generator, which upon a trigger signal instantaneously conducts gas into an air bag made of a substantially air-impermeable material. The air bag has an air outlet opening, through which gas flows out of the air bag after a dwell time in the air bag. It is proposed that the effective opening diameter of the air outlet opening (40) is opened in a time-delay manner after the activation of the time module. If necessary, the volume can be increased briefly in order to keep the internal pressure constant in the air bag for a predetermined time period.
