Title:
SAFETY AIRBAG AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/121792
Kind Code:
A1
Abstract:
The present invention relates to a safety airbag and a manufacturing method therefor. The safety airbag comprises a polyester fabric for safety airbags, a silica gel coating, and a safety valve, wherein the polyester fabric for safety airbags comprises a double-layer woven fabric formed by interweaving warp yarns and weft yarns; all the warp yarns on the double-layer woven fabric are parallel to a plane in which any curved warp yarn is located, and all the weft yarns thereon are parallel to a plane in which any curved weft yarn is located; and the warp density is the same all over and so is the weft density. The manufacturing method comprises: weaving a polyester fabric for safety airbags, providing an air intake hole on the upper portion of the polyester fabric, which air intake hole is used for connecting to a gas generator to manufacture an air bag of a safety airbag; uniformly spraying a layer of silica gel inside the fabric to form a silica gel coating and performing a vulcanization treatment; and then installing a safety valve to obtain the safety airbag. By means of the method for manufacturing a safety airbag of the present invention, a fabric with a curved shape can be directly woven. The method is simplified with respect to a composite molding process; and the manufactured safety airbag is low cost, has good mechanical properties, and has high safety.
