## Abstract

A safety airbag mesh, which includes a fiber layer. The fiber layer includes a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise, characterized in that the warp fiber unit includes a plurality of first fibers and second fibers arranged weftwise. The first fibers warpwise cover a buffer area and a support area, and the first fibers in the buffer area take on nonlinear formation, and extend longer than the second fibers in the area.

## Claims

### Claim 1

A safety airbag mesh comprising a fiber layer, the fiber layer comprising a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise, characterized in that the warp fiber unit comprises a plurality of first fibers and second fibers arranged weftwise, the first fibers warpwise are at least partially located in a buffer area and a support area, and the first fibers in the buffer area take on nonlinear formation, and extend longer than second fibers in the buffer area, the safety airbag mesh further comprises one or more weft fiber wires, the weft fiber wires are arranged in the buffer area, and connected to all the first fibers arranged weftwise in a proper sequence,
wherein after deployment of the safety airbag mesh, the one or more weft fiber wires remain connected to the first fibers.

### Claim 2 (depends on 1)

The safety airbag mesh of claim 1, wherein the safety airbag mesh comprises one weft fiber wire, the first fibers take on a triangle formation in the buffer area, and a plurality of first fibers are arranged weftwise in a proper sequence in the buffer area.

### Claim 3 (depends on 1)

The safety airbag mesh of claim 1, wherein the safety airbag mesh comprises a plurality of weft fiber wires, and the weft fiber wires cause the first fibers to take on a polygonal formation in the buffer area.

### Claim 4 (depends on 1)

The safety airbag mesh of claim 1, wherein the weft fiber wire(s) is securely woven together with the first fibers.

### Claim 5 (depends on 1)

The safety airbag mesh of claim 1, wherein the weft fiber wire(s) is securely spliced together with the first fibers.

### Claim 6 (depends on 1)

The safety airbag mesh of claim 1, wherein the first fibers have greater tensile strength than that of the second fibers and the weft fiber wire.

### Claim 7 (depends on 1)

The safety airbag mesh of claim 1, wherein the first fibers comprise two or more bunches of interwoven fibers.

### Claim 8 (depends on 1)

The safety airbag mesh of claim 1, wherein the first fibers are made up of at least one of the following materials: aromatic polyamide fibers, polyester fibers, nylon fibers, carbon fibers, and glass fibers.

### Claim 9 (depends on 1)

The safety airbag mesh of claim 1, wherein the second fibers are made up of at least one of the following materials: aromatic polyamide fibers, polyester fiber, nylon fibers, carbon fibers and glass fibers.

### Claim 10 (depends on 1)

The safety airbag mesh of claim 1, wherein the weft fiber wire is made up of at least one of the following materials: aromatic polyamide fibers, polyester fiber, nylon fibers, carbon fibers or glass fibers.
