Analysis of Fabrics and Seams in Airbags

Airbag fabrics belong to the group of heavy synthetic fabrics. Due to relatively coarse synthetic multifilament warp and weft yarns and high density, the weaving of these fabarics is very demanding. Apart from that, joining parts of the airbag using sewn seams requires special sewing machines and automata. The impact of individual sewing parameters as thread tension and fineness, needle type and thickness, stitch type and length on the quality of the joint are of exceptional importance for passenger safety. This paper analyses the construction parameters of the fabrics used for different airbags. The types of sewn seams and stitch length will be investigated. The mechanical properties of seamed and seamless fabrics will be tested. Thread types and properties will be examined. Investigations of the airbag shape and size depending on the use will be investigated.
