Description

Technical Field

[0001] This utility model discloses a webbing technology, and in particular relates to a cushioning webbing. Background Technology

[0002] Existing webbing primarily uses a plain weave structure, exhibiting near-linear tensile characteristics under impact loads, making it difficult to provide the desired "soft-then-hard" cushioning curve. Current solutions often rely on adhesive layers, foam layers, or elastomer interlayers to achieve elongation and energy absorption; however, these solutions are complex to manufacture, have limited durability and environmental adaptability, and are unsuitable for narrow-width, high-speed weaving. Therefore, there is an urgent need for a structured cushioning solution that does not alter the material system, achieving multi-stage energy absorption and containment. Utility Model Content

[0003] The purpose of this invention is to provide a cushioning webbing to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a buffer webbing, comprising a main bearing warp, a buffer warp, a stretch-limiting warp, and a weft, and a plurality of buffer units are periodically arranged along the length of the webbing, wherein the buffer unit comprises a corrugated buffer zone, a transition zone, and a limit bearing zone connected in sequence;

[0005] The corrugated buffer zone adopts a combination of long floating weft and spaced connection. In the combination structure, the weft yarn forms flattenable peaks or valleys in the thickness direction of the weft tape.

[0006] The limiting bearing area adopts a high-density bonding structure and connects the limiting warp and weft yarns; the transition area is formed by a structure with a gradually changing number of bonding points.

[0007] Preferably, in the repeating unit of the corrugated buffer zone, the length of the long float is 5 warp distances, and the ratio of long float to connection is 5:2.

[0008] Preferably, the limiting bearing area adopts a plain weave, and the warp density of this area is 20% higher than that of the corrugated buffer zone.

[0009] Preferably, the limiting warp yarn C is made of low-elongation, high-strength fiber, and the cushioning warp yarn B is made of fiber with relatively high elongation compared to the limiting warp yarn C.

[0010] Preferably, the length L of each buffer unit is 8-30mm, and the length ratio of the corrugated buffer zone to the limiting bearing zone is 2:1.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model overcomes the shortcomings of using adhesive layers, foam layers, or elastomer interlayers to achieve elongation and energy absorption, which are complex, have limited durability and environmental adaptability and cannot be applied to narrow-width webbing, through an organized design of long floating weft corrugations, connecting gradients, and limiting warp yarns. It achieves multi-level buffering and limiting of narrow-width webbing. Attached Figure Description

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0017] A type of cushioning webbing, such as Figures 1-2 As shown, it includes main bearing warp A, buffer warp B, stretch limiting warp C and weft D, and several buffer units 1 are periodically arranged along the length of the webbing. The buffer unit 1 includes a corrugated buffer zone 2, a transition zone 3 and a limiting bearing zone 4 connected in sequence.

[0018] Among them, the corrugated buffer zone 2 adopts a combination structure of long floating weft and interval connection. In the combination structure, the weft yarn forms flattenable peaks or valleys in the thickness direction of the webbing.

[0019] The limiting bearing area 4 adopts a high-density bonding structure and connects the limiting warp yarn C with the weft yarn D; the transition area 3 is formed by a structure with a gradually varying number of bonding points. In the repeating unit of the corrugated buffer zone 2, the length of the long float weft is 5 warp pitches, and the ratio of long float to bonding is 5:2; the limiting bearing area 4 adopts a plain weave, and the warp density in this area is 220% higher than that of the corrugated buffer zone 2; the limiting warp yarn C adopts low-elongation high-strength fiber, and the buffer warp yarn B adopts fiber with relatively higher elongation than the limiting warp yarn C; the length L of each buffer unit 1 is 8-30mm, and the length ratio of the corrugated buffer zone 2 to the limiting bearing area 4 is 2:1.

[0020] Example 1

[0021] Material allocation:

[0022] A: 1000D high-strength polyester filament; B: 840D nylon filament; C: 600D aramid; D: 500D polyester.

[0023] Tissue and density:

[0024] 25-wave buffer zone: 5 / 1 satin weave variant forms long float weft, long float = 5 warp pitch; the connection point is twice every 5 warp; the warp / weft density is 44 threads / 10mm and 32 threads / 10mm respectively.

[0025] Transition zone 36: A stepped connection consisting of 5 / 1 satin → 3 / 1 twill → plain weave, with a length accounting for 20% of buffer unit 1.

[0026] Limiting bearing area 47: plain weave, with the warp density increased to 52 threads / 10mm.

[0027] Among them, the ratio of corrugated buffer zone 2: transition zone 3: limiting bearing zone 4 is 10:3:3, and the edge is provided with a twisted edge 9 to stabilize the wave crest; under the initial load, the wave crest flattens to provide stroke; when the load continues to increase, C is connected to the high-density connecting pipe and the extension is limited.

[0028] Example 2

[0029] In the corrugated buffer zone 25 of Example 1, double wefts D1 and D2 are inserted every other weft, wherein the linear density of D2 is 1.5 times that of D1, forming a yarn storage channel; the structure maintains a 5 / 1 long float, but short floats are introduced locally to supplement the connection to prevent large-area snagging, which is suitable for shoulder straps or climbing straps that require a larger flattening stroke.
