DETAILED DESCRIPTION OF THE INVENTION

[0028] By reference to FIGS. 1-5, what follows is a further description of the embodiment of the safety airbag mesh of the invention.

[0029] In the description of the invention, it should be noted that for nouns of locality, terms that indicate directions or locations, such as “central”, “horizontal (X)”, “longitudinal (Y)”, “vertical (Z)”, “length”, “width”, “thickness”, “up”, “down”, “front”, “rear”, “left”, “right”, “upright”, “level”, “top”, “bottom”, “inside”, “outside”, “clockwise”, and “anticlockwise”, are based on directions or locations represented in figures, which are used for giving a brief description to the invention only, instead of indicating or implying that relevant devices or elements must be in specific directions, be structured or operated in specific directions. And the terms shall not be defined to restrict the specific scope of protection of the invention.

[0030] Besides, terms, such as “first” and “second”, are for descriptive purposes only, which cannot be defined to indicate or imply relative significance or imply quantity that specifies any technical characteristics. Thus, those defining such characteristics as “first” and “second” may indicate or imply one or more characteristics of the like. In the description of the invention, “a couple of” and “a plurality of” indicate two or more, unless otherwise specified.

[0031] The safety airbag mesh comprises a fiber layer. The fiber layer is composed of a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise. The warp fiber unit comprises a plurality of first fibers and second fibers arranged weftwise. The first fibers warpwise cover a buffer area and a support area. The first fibers in the buffer area take on nonlinear formation. The first fibers in the buffer area extend longer than the second fibers in the area. The fiber layer also comprises a weft fiber wire. The weft fiber wire is arranged in the buffer area and connected to all the first fibers arranged weftwise in proper sequence.

[0032] As shown in FIGS. 1 and 2, for the invention, the support area 1 is arranged at both sides of buffer area 2, with a breadth of each support area subject to the length of the second fibers 32 in the buffer area, when the first fibers 31 in the buffer area shall extend longer than that of the second fibers 32 in the area.

[0033] Moreover, the weft fiber unit of the invention may also comprise third fibers woven with the first fibers and second fibers in the support area, so as to secure the structural strength of the support area with no loosening.

[0034] Furthermore, the invention may be arranged with the weft fiber wire 5 as well. In FIG. 1, there is one weft fiber wire 5 arranged, which draws all the first fibers 31 from the center to the left shown in FIG. 1. Alternatively in other embodiments, the weft fiber wire 5 may draw all the first fibers 31 from the center to the right shown in FIG. 1. So long as the drawing direction may be vertical to the weft or slightly inclined towards the weft or warp on the plane of the fiber layer, making the first fibers 31 will take on a triangular formation in the buffer area, a plurality of first fibers 31 arranged weftwise will levelly take on a regular formation in the buffer area, instead of overlaying each other.

[0035] As shown in FIG. 3, when the airbag pops open, the second fibers 32 will be snapped, and so will the weft fiber wire 5, making the first fibers 31 in the buffer area successfully drawn open.

[0036] In the invention, the first fibers 31 have greater tensile strength than that of the second fibers 32 and the weft fiber wire 5.

[0037] The first fibers 31 may be in a single bundle of fibers or two or more bundles of interwoven fibers, for avoiding splash of plastic fragments with greater tensile strength.

[0038] In practical use, a plurality of the first fibers may be arranged at the same time, e.g., two bundles of fibers and three bundles of fibers in an alternate arrangement, or arrangements of the like.

[0039] Preferably in the embodiment, the weft fiber wire 5 is securely woven together with the first fibers 31. For instance, the weft fiber wire may be woven in the fiber layer with the overlap between the weft fiber wire and the first fibers secured, so that the weft fiber wire as drawn can draw the first fibers altogether to straighten the first fibers.

[0040] In another embodiment, the weft fiber wire 5 may also be securely spliced with the first fibers 31 by glue or hot melting.

[0041] Preferably in the embodiment, the first fibers are made up of aromatic polyamide fibers, polyester fibers, nylon fibers, carbon fibers, or glass fibers, individually or in combination.

[0042] Further preferably, the second fibers are made up of aromatic polyamide fibers, polyester fiber, nylon fibers, carbon fibers, or glass fibers, individually or in combination.

[0043] Further preferably, the weft fiber wire is made up of aromatic polyamide fibers, polyester fiber, nylon fibers, carbon fibers, or glass fibers, individually or in combination.

[0044] In alternative embodiments, n weft fiber wires are arranged, wherein n is a positive integer that is greater than or equal to 2, and n weft fiber wires cause the first fibers to take on a polygonal formation in the buffer area.

[0045] For instance, as shown in FIG. 4, there are two weft fiber wires 5 arranged, both of which draw leftward the first fibers 31 in the buffer area, making the first fibers 31 take on a trapezoidal formation in the buffer area.

[0046] And as shown in FIG. 5, there are two weft fiber wires 5 arranged, but the two weft fiber wires draw the first fibers 31 in opposite directions, making the first fibers 31 take on a broken line formation in the buffer area.

[0047] Likewise, those skilled in the art may also arrange a plurality of weft fiber wires or set the direction in which each weft fiber wire draws the first fibers, making the first fibers neatly arranged in the buffer area irrespective of the number of the weft fiber wires arranged or the direction in which the first fibers are drawn.

[0048] The above outlines preferable modes of the invention only. Not confined to the preceding embodiments, the scope of protection of the invention covers all technical schemes following the thread of the invention. It should be noted that ordinary skilled persons in the technical field may make a plurality of modifications and rectifications on the principle of the invention. which shall be seen as within the scope of protection of the invention.
