A pair of symmetrically distributed first and second limiting constraint fabric pieces are fixed to the upper surface of the first elastic webbing by a sewing process. A tension-responsive deformation component is installed between the first and second limiting constraint fabric pieces through a limiting fit. By installing the tension-responsive deformation component, which consists of limiting constraint fabric pieces, arc-shaped deformation columns, and limiting blocks, in the elastic webbing, and cooperating with the elastic airbag unit in the middle, the webbing achieves the purpose of adaptive cushioning adjustment. When the external tension changes during carrying, the arc-shaped deformation column is straightened from an arc shape, driving the elastic airbag unit to change from a flat state to a convex state.

Description

Technical Field

[0001] This utility model relates to the field of elastic webbing technology, and in particular to a comfortable elastic webbing. Background Technology

[0002] In everyday carrying items such as school bags and backpacks, the shoulder straps are the main load-bearing components, and their comfort directly affects the user experience. Traditional shoulder straps mostly use ordinary webbing or add fixed padding to provide a certain cushioning effect. However, the existing shoulder strap structure still lacks a technical solution that can adaptively adjust the cushioning force in real time under dynamic load scenarios, making it difficult to meet users' needs for a personalized, intelligent, and comfortable carrying experience.

[0003] Currently, most shoulder straps on carrying equipment on the market use a single elastic webbing material. In actual use, these straps suffer from a mismatch between their cushioning performance and user needs. The fixed padding cannot adjust its support strength according to different users' loads and activity levels, easily becoming too soft initially or collapsing and deforming after long-term use, failing to achieve the ideal comfortable support effect. Therefore, we propose a comfortable elastic webbing to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a comfortable elastic webbing that can solve the problem that most shoulder straps of current carrying products on the market use a single elastic material webbing. In actual use, such shoulder straps have the problem that the force cushioning performance does not match the user's needs. The fixed filling cannot adjust the support strength according to different users' load and exercise status, and is prone to being too soft at the beginning or collapsing and deforming after long-term use, making it difficult to achieve the ideal comfortable support effect.

[0006] To solve the above-mentioned technical problems, this utility model provides a comfortable elastic webbing, which adopts the following technical solution: it includes a first elastic webbing, and a pair of symmetrically distributed first and second limiting constraint fabric pieces are fixed to the upper surface of the first elastic webbing by a sewing process. The first and second limiting constraint fabric pieces are both provided with double opening structures on their inward sides. A tension-responsive deformation component is installed between the first and second limiting constraint fabric pieces by a limiting fit.

[0007] Optionally, the tensile-responsive deformation component includes a first arc-shaped deformation column, a second arc-shaped deformation column, a first limiting block, and a second limiting block. The first limiting block and the second limiting block are symmetrically arranged in the first limiting constraint fabric and the second limiting constraint fabric. The opposing sides of the first limiting block and the second limiting block are provided with barbed hook-shaped engaging structures. The first limiting constraint fabric and the second limiting constraint fabric completely cover the first limiting block and the second limiting block.

[0008] Optionally, a first arc-shaped deformation column and a second arc-shaped deformation column are installed between the first limiting block and the second limiting block. The arc-shaped deformation column extends to the outside through the double-opening structure on the first limiting constraint cloth and the second limiting constraint cloth. The first arc-shaped deformation column and the second arc-shaped deformation column have a symmetrical outward convex arc-shaped structure in the initial non-stressed state.

[0009] Optionally, an elastic airbag unit is provided between the first arc-shaped deformable column and the second arc-shaped deformable column. The elastic airbag unit forms a closed gas-containing chamber inside. The two sides of the elastic airbag unit are connected to the arc-shaped deformable column through integrally formed fixing lugs. The fixing lugs have a through-hole in the middle. The first arc-shaped deformable column and the second arc-shaped deformable column limit and fix the elastic airbag unit through the limiting hole.

[0010] Optionally, a second elastic webbing is sewn onto the top of the first elastic webbing, and the first and second elastic webbing completely enclose the limiting restraint fabric, the tension-responsive deformation component, and the elastic airbag unit.

[0011] Optionally, when the first elastic webbing and the second elastic webbing are subjected to external tension, the first elastic webbing and the second elastic webbing deform and elongate, causing the limiting constraint cloth to pull the first arc-shaped deformation column and the second arc-shaped deformation column to stretch. During the process of the arc-shaped deformation column being straightened from an arc-shaped structure, the elastic airbag unit located between the two changes from a flat state to a convex state, and the degree of convexity is positively correlated with the magnitude of the external tension.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By installing a tension-responsive deformation component consisting of a limiting constraint cloth, an arc-shaped deformation column, and a limiting block inside the first elastic webbing and the second elastic webbing, and in conjunction with the intermediate elastic airbag unit, the webbing achieves the purpose of adaptive buffer adjustment. When the external tension changes during the carrying process, the arc-shaped deformation column is straightened from an arc shape, driving the elastic airbag unit to change from a flat state to a convex state. The degree of convexity is positively correlated with the magnitude of the tension, which can disperse shoulder pressure in real time and avoid the problem of insufficient comfort caused by the fixed buffer structure of traditional shoulder straps.

[0013] 2. By adopting a double-layer wrapping structure of first elastic webbing and second elastic webbing, the limiting restraint fabric, deformation components and airbag unit are completely covered inside, which achieves the purpose of protecting the internal precision structure and enhancing the overall durability. This design prevents the internal components from being scratched or worn by the outside, ensuring the stability of tensile force transmission and airbag deformation. On the other hand, it makes the webbing more regular in appearance. Moreover, the double-layer elastic webbing itself has good toughness and resilience, which works in synergy with the internal self-adaptive structure to ensure that the webbing can still maintain stable and reliable cushioning performance under long-term high-frequency use.

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0026] Example 1, refer to Figure 1-4In this embodiment, to address the problem that most shoulder straps on current commercially available backpacks use a single elastic material, which leads to a mismatch between the cushioning performance and user needs, and the inability of the fixed padding to adjust the support strength according to different user loads and exercise states, resulting in initial softness or collapse and deformation after long-term use, thus failing to achieve the ideal comfortable support effect, this utility model discloses a comfortable elastic webbing.

[0027] The system includes a first elastic webbing 1. A pair of symmetrically distributed first limiting constraint fabric pieces 3 and second limiting constraint fabric pieces 4 are fixed to the upper surface of the first elastic webbing 1 by sewing. The first limiting constraint fabric pieces 3 and the second limiting constraint fabric pieces 4 are both provided with double opening structures 31 facing inward. A tension-responsive deformation component 5 is installed between the first limiting constraint fabric pieces 3 and the second limiting constraint fabric pieces 4 through a limiting fit. By fixing the symmetrically distributed first limiting constraint fabric pieces 3 and the second limiting constraint fabric pieces 4 to the upper surface of the first elastic webbing 1 and installing the tension-responsive deformation component 5 between the first limiting constraint fabric pieces 3 and the second limiting constraint fabric pieces 4, the purpose of adaptively adjusting the cushioning performance of the webbing under force is achieved. This allows the webbing to dynamically change the degree of protrusion of the internal elastic airbag unit 6 according to different tensile forces during the carrying process.

[0028] The tension-responsive deformation component 5 includes a first arc-shaped deformation column 51, a second arc-shaped deformation column 52, a first limiting block 53, and a second limiting block 54. The first limiting block 53 and the second limiting block 54 are symmetrically arranged in the first limiting constraint fabric 3 and the second limiting constraint fabric 4. Both the first limiting block 53 and the second limiting block 54 have barbed hook-shaped engaging structures 531 on their facing sides. The first limiting constraint fabric 3 and the second limiting constraint fabric 4 completely cover the first limiting block 53 and the second limiting block 54. A tension-responsive deformation assembly 5, comprising a first arc-shaped deformation column 51, a second arc-shaped deformation column 52, a first limiting block 53, and a second limiting block 54, is set between the limiting and constraining fabric pieces 4. The hook-shaped interlocking structure 531 of the first limiting block 53 and the second limiting block 54 is used to achieve stable positioning, thereby controlling the deformation of the first elastic webbing 1 and the second elastic webbing 2 under stress. Under the action of external tension, the arc-shaped deformation column can be straightened in an orderly manner to drive the elastic airbag unit 6 to expand, ensuring that the tension-responsive deformation assembly 5 is stable and does not shift within the webbing.

[0029] A first arc-shaped deformable column 51 and a second arc-shaped deformable column 52 are installed between the first limiting block 53 and the second limiting block 54. The arc-shaped deformable columns extend to the outside through the double-opening structure 31 on the first limiting constraint fabric 3 and the second limiting constraint fabric 4. The first arc-shaped deformable column 51 and the second arc-shaped deformable column 52 have a symmetrical outward convex arc-shaped structure in the initial non-stressed state. This is achieved by installing a symmetrical outward convex arc-shaped structure between the first limiting block 53 and the second limiting block 54. The first arc-shaped deformable column 51 and the second arc-shaped deformable column 52 extend to the outside through the double-opening structure 31 on the first limiting constraint fabric 3 and the second limiting constraint fabric 4, thereby achieving the purpose of converting the external tension into a tension-responsive deformation component 5 shape change. As the tension increases, the first arc-shaped deformable column 51 and the second arc-shaped deformable column 52 are gradually straightened and the middle elastic airbag unit 6 is squeezed to expand, so that the webbing can dynamically adjust the buffer force according to the actual stress.

[0030] An elastic airbag unit 6 is provided between the first arc-shaped deformable column 51 and the second arc-shaped deformable column 52. The elastic airbag unit 6 forms a closed gas-containing chamber 61 inside. The elastic airbag unit 6 is connected to the arc-shaped deformable column on both sides through integrally formed fixing lugs 62. The fixing lugs 62 have a through limiting hole 621 in the middle. The first arc-shaped deformable column 51 and the second arc-shaped deformable column 52 limit and fix the elastic airbag unit 6 through the limiting hole 621. By setting the elastic airbag unit 6, which forms a closed gas-containing chamber 61 inside, between the first arc-shaped deformable column 51 and the second arc-shaped deformable column 52, and using the integrally formed fixing lugs 62 and limiting holes 621 on both sides of the elastic airbag unit 6 to limit and fix it to the arc-shaped deformable column, the shape change of the arc-shaped deformable column is transformed into the expansion of the elastic airbag unit 6.

[0031] A second elastic webbing 2 is sewn to the top of the first elastic webbing 1. The first elastic webbing 1 and the second elastic webbing 2 completely wrap the limiting restraint fabric, the tension-responsive deformation component 5, and the elastic airbag unit 6. By sewing the second elastic webbing 2 to the top of the first elastic webbing 1 and using the first elastic webbing 1 and the second elastic webbing 2 to completely wrap the limiting restraint fabric, the tension-responsive deformation component 5, and the elastic airbag unit 6, the purpose of protecting the internal functional structure is achieved. This makes the webbing look neater and more uniform, and avoids wear and scratches on the internal components during actual use.

[0032] When the first elastic webbing 1 and the second elastic webbing 2 are subjected to external tension, they deform and elongate, causing the limiting constraint fabric to pull the first arc-shaped deformation column 51 and the second arc-shaped deformation column 52 to stretch. During the process of the arc-shaped deformation column being straightened from its arc-shaped structure, the elastic airbag unit 6 located between them changes from a flat state to a convex state, and the degree of convexity is positively correlated with the magnitude of the external tension. By utilizing the characteristic that the first elastic webbing 1 and the second elastic webbing 2 deform and elongate under external tension, the limiting constraint fabric is used to pull the first arc-shaped deformation column 51 and the second arc-shaped deformation column 52 to stretch, thus realizing the process of converting external tension into a change in the shape of the elastic airbag unit 6. This achieves the goal of making the degree of convexity of the elastic airbag unit 6 positively correlated with the magnitude of the external tension, and ultimately obtains the effect of automatically adjusting the cushioning force according to the actual carrying pressure.

[0033] The specific working principle is as follows: by installing a tension-responsive deformation component 5 consisting of a limiting constraint fabric piece, an arc-shaped deformation column, and a limiting block in the first elastic webbing 1 and the second elastic webbing 2, and in conjunction with the elastic airbag unit 6 in the middle, the webbing achieves the purpose of adaptive cushioning adjustment. When the external tension changes during the carrying process, the arc-shaped deformation column is straightened from an arc shape, driving the elastic airbag unit 6 to change from a flat state to a convex state. The degree of convexity is positively correlated with the magnitude of the tension, which can distribute the shoulder pressure in real time and avoid the problem of insufficient comfort caused by the fixed cushioning structure of traditional shoulder straps. By employing a double-layer wrapping structure of the first elastic webbing 1 and the second elastic webbing 2, the limiting restraint fabric, deformation components, and airbag unit are completely enclosed, achieving the purpose of protecting the internal precision structure and enhancing overall durability. This design, on the one hand, prevents the internal components from being scratched or worn by the outside, ensuring the stability of tensile force transmission and the deformation of the elastic airbag unit 6. On the other hand, it makes the webbing appearance more regular, and the double-layer elastic webbing itself has good toughness and resilience, working in synergy with the internal adaptive structure to ensure that the webbing can still maintain stable and reliable cushioning performance under long-term high-frequency use.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
