- 2. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein the pyrotechnic charge is formed as an explosive thread, said explosive thread being introduced into the textile material of the gas bag or being applied onto the textile material of the gas bag.
-
6. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein said pyrotechnic charge comprises a filament and an explosive coating, the filament being introduced into the gas bag or applied onto the gas bag and the explosive coating being applied onto the gas bag in the region of the filament.
-
7. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein said pyrotechnic charge comprises an explosive coating made of an electrically conductive explosive and two connection lines, said coating being applied between said two connection lines onto the gas bag such that the explosive coating electrically contacts the two connection lines.
-
8. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein the pyrotechnic charge is associated to the gas bag at an inner side of the gas bag.
-
9. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein several ignitable pyrotechnic charges are arranged in a parallel connection with common connection lines.
-
10. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein connection lines for the ignitable pyrotechnic charge are applied onto the textile material of said gas bag introduced into the textile material of said gas bag.
-
11. A device for venting a gas bag made of a textile material, comprising at least one ignitable pyrotechnic charge which is associated to the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge wherein a region of the gas bag, in which the pyrotechnic charge is associated to the gas bag, is circumscribed by at least one seam.
- 12. A passenger restraint system for a vehicle, comprising at least one airbag made of a textile material, said airbag having at least one pyrotechnic charge associated therewith in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge inflator means for inflating said airbag a control device for controlling the deployment of said airbag, and sensor means for detecting a pressure exerted by the airbag on the passenger, wherein said control device triggers the ignition of said pyrotechnic charge based on a pressure signal detected by the sensor means when a predetermined threshold value is exceeded.
