Claims
- 1. An uncoated, tightly woven, synthetic filament yarn fabric for manufacturing an air bag, wherein the yarn used to construct the fabric is a polyamide yarn having a filament linear density of less than 4 dtex and a yarn linear density of 200-600 dtex, and wherein said fabric has a specific stiffness of <1.0.times.10.sup.-2 and an air permeability <10 l/dm.sup.2 .multidot.min, said air permeability obtained by shrinking the fabric in a wet process.
- 2. The fabric according to claim 1, wherein the fabric has an at least substantially symmetrical sett.
- 3. The fabric according to claim 1, wherein the fabric is wet treated in a temperature range of 60.degree.-140.degree. C.
- 4. The fabric according to claim 3, wherein the fabric is wet treated in a temperature range of 60.degree.-140.degree. C. in the absence of any prior or subsequent heat setting.
- 5. The fabric according to claim 1, wherein the polyamide yarn has a filament linear density of from about 0.5 dtex to 3.9 dtex.
- 6. The fabric according to claim 5, wherein the polyamide yarn has a filament linear density of from about 2.0 dtex to 3.9 dtex.
- 7. An air bag made of the fabric of claim 1.
- 8. An air bag system comprising an air bag according to claim 7.
- 9. An air bag made of the fabric of claim 4.
- 10. An air bag system comprising an air bag according to claim 9.
