The available fabric mass in the one-piece woven airbag as tailorized by the method, now makes it possible to reinforce the airbag fabric individually oriented. Thus, at a high stress location formerly exhibiting airbag tears, a fabric quality is now available of enhanced resistance, achieved among other things by an increase in the thermal capacity in the neuralgic locations of the airbag where namely the jet lances feature their so-called jet gill zone.

1. A method for machine weaving an at least two-ply, one-piece airbag or air tube comprising:weaving weft threads of differing dTex in at least one ply and, picking said weft threads only in predetermined warp thread length regions, and interweaving part of said weft threads only in predetermined and non-overlapping overlapping width regions of the airbag. 2. The method as set forth in claim 1 further comprising non-interwoven regions of said weft threads are parted from the airbag or air tube as just woven in the weaving machine.3. The method as set forth in claim 1 further comprising picking, on the one hand, standard weft threads of a first dtex and, on the other, reinforcement weft threads having a second, more particularly at least 25% higher dtex.4. The method as set forth in claim 3 further comprising picking said weft threads having the second, higher dtex with no change in the weft set.5. The method as set forth in claim 1 further comprising employing monofil threads as said weft threads.6. A method for manufacturing an inflatable safety device, the method comprising:(a) weaving threads of a lower dTex value in a first area; (b) weaving threads of a higher dTex value in a second area; and (c) weaving threads of the higher dTex value in a third area; wherein the first area is located between the second and third areas, the second and third areas not overlapping each other. 7. A method for manufacturing an airbag or passenger restraint air tube, the method comprising:(a) weaving a first reinforced area at a first gas inflation location; (b) weaving a second reinforced area at a second gas inflation location, the first and second locations being in fluid communication with each other, and (c) weaving a non-reinforced area between the inflation locations. 8. An inflatable safety device comprising:(a) threads of a lower dTex value in a first area; (b) threads of a higher dTex value in a second area; and (c ) threads of the higher dTex value in a third area; wherein the first area is located between the second and third areas, the second and third areas not overlapping each other; wherein the material is more easily folded in the first area as compared to the second and third areas.
