Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
179 words
An airbag device in a motor vehicle, the motor vehicle including a body having two side walls, a roof, and an A-pillar and a C-pillar extending to the roof, said airbag device comprising: an airbag consisting of an inflatable gas cushion; a gas generator for filling the airbag; a gas conduction pipe which extends through a separated region of the airbag; at least one outlet opening in the gas conduction pipe; a profile strip, reinforced by an incorporated structure band, having a substantially U-shaped cross-section and with a shooting channel formed therein, in which the airbag is laid in stacked folds and is received, and in which the gas conduction pipe is received, wherein the profile strip with the airbag and gas conduction pipe extends along one side of the vehicle from the A-pillar to the C-pillar and is arranged on the vehicle body in a transition region from the vehicle roof and one side wall of the vehicle; and a plurality of attachment elements for holding a construction unit comprising the profile strip, airbag and gas conduction pipe.
