Abstract
The application relates to an OPW airbag which is woven into a part, comprising warp threads and weft threads, which are woven so as to produce at least three woven fabric layers, a lower fabric layer (UG), an upper fabric layer (OG), and a central fabric layer (MG) arranged therebetween. The airbag is characterized in that the warp threads and weft threads of the central fabric layer (MG) float in a selected through-flow region (DSB).
Claims7
A one piece woven (OPW) airbag with warp threads and weft threads which are woven in at least three woven fabric layers, a lower woven fabric layer (UG), an upper woven fabric layer (OG) and a middle woven fabric layer (MG) arranged in between,
- wherein the warp and weft threads of the middle woven fabric layer (MG) are interwoven in a basic weave,
- wherein in a selected throughflow region (DSB) located within the middle woven fabric layer (MG), the warp and weft threads of the middle woven fabric layer (MG) are configured to lie within the middle woven fabric layer (MG) and be displaced parallel and transversely with respect to a running direction thereof,
- wherein the middle woven fabric layer (MG) is permeable to air in the throughflow region (DSB), and
- wherein the throughflow region (DSB) is surrounded by a border region as reinforcement, the border region having a tighter weave than the basic weave of the middle woven fabric layer (MG).
