Abstract
An airbag cushion having a novel seam structure including either a tri-stitch fold-over seam structure or a double-stitch fold-over seam structure. The novel seam structure allows airbag cushions to be manufactured by using low tenacity yarns, preferably in the range of between about 40 cN/tex and about 65 cN/tex.
Claims18
An airbag cushion comprising:
- at least one fabric blank including multifilament yarns having a tenacity of no greater than about 40 cN/tex, wherein said blank has an elongation in each of the warp and filling directions of less than 40%.
An airbag cushion comprising:
- at least one fabric blank including multifilament yarns having a tenacity of no greater than about 55 cN/tex, wherein said blank has an elongation in each of the warp and filling directions of less than 40%, said airbag cushion further comprising at least one tri-stitch fold-over seam structure.
An airbag cushion comprising:
- at least one fabric blank including multifilament yarns having a tenacity of no greater than about 55 cN/tex, wherein said blank has an elongation in each of the warp and filling directions of less than 40%, said airbag cushion further comprising at least one double-stitch fold-over seam.
An airbag cushion having a tri-stitch fold-over seam, said cushion having at least one fabric blank including multifilament yarns with a tenacity of no greater than about 60 cN/tex.
An airbag cushion having a double-stitch fold-over seam, said cushion having at least one fabric blank including multifilament yarns with a tenacity of no greater than about 60 cN/tex.
An airbag cushion comprising:
- (a) at least one fabric blank, said fabric blank having multifilament yarns with a tenacity of no greater than about 40 cN/tex, and
- (b) further wherein said fabric blank has an elongation in each of the warp and filling directions of less than 40%.
