Description
Technical Field
[0001] The utility model relates to the technical field of sleep products, in particular to a wire-drawing airbag and an airbag mattress. Background Art
[0002] A mattress is one of the indispensable articles in people's daily life, and its comfort directly affects people's sleep quality. With the development of technology, the manufacturing technology of mattresses is also constantly progressing. Among them, airbag mattresses are favored by consumers due to their good comfort and support. The main principle of an airbag mattress is to change the softness and hardness of the mattress by inflating and deflating to meet different sleep needs.
[0003] To improve comfort, airbag mattresses usually have multiple inflatable airbags to independently control the support air pressure for different sleep zones. Ideally, each inflatable airbag is a standard cuboid structure. Therefore, the top surfaces of two adjacent inflatable airbags are closely attached without gaps.
[0004] In fact, referring to Figure 1 , after the inflatable airbag 1 is inflated, the inflatable airbag 1 will undergo an outward expansion deformation. Specifically, each surface of the inflatable airbag 1 will present an arc structure with the middle arched outward, and a support gap 2 will be formed between the top surfaces of two adjacent inflatable airbags. When a user lies in the position where the support gap 2 is located, the sleep comfort significantly decreases.
[0005] Therefore, it is necessary to improve the existing inflatable airbag to solve the problem that there is a large support gap between the top surfaces of two adjacent airbags, resulting in poor sleep comfort.
[0006] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art already known to those of ordinary skill in the art. Summary of the Utility Model
[0007] An object of the present utility model is to provide a wire-drawing airbag and an airbag mattress, which can effectively solve the problem that there is a large support gap between the top surfaces of two adjacent airbags, resulting in poor sleep comfort.
[0008] To achieve the above object, on the one hand, the present utility model provides a wire-drawing airbag, including:
[0009] An airbag body provided with an inner space;

[0039] The utility model provides a wire-drawing airbag and an airbag mattress, which are applicable to the application scenario of providing sleep support for the human body, and can effectively solve the problem that there is a large support gap between the top surfaces of two adjacent airbags, resulting in poor sleep comfort.
[0040] This embodiment provides an airbag mattress, which includes a bed frame and a plurality of wire-drawing airbags located inside the bed frame. Preferably, the number of the wire-drawing airbags is at least two, and two adjacent wire-drawing airbags are arranged in a fitting manner.
[0041] See Figure 2 , in this embodiment, the wire-drawing airbag includes an airbag body 3 and an internal pulling structure 4. The airbag body 3 is provided with an internal space; the internal pulling structure 4 is located in the internal space and is connected to the airbag body 3 to inhibit the outward expansion deformation of the airbag body 3.
[0042] For the wire-drawing airbag provided in this embodiment, the internal pulling structure 4 is arranged inside the airbag body 3. After the internal space is inflated, the internal pulling structure 4 will tighten the walls of the internal space, limit the outward arching of the surfaces of the airbag body 3, and greatly reduce the degree of outward expansion deformation of the airbag body 3. After the degree of outward expansion deformation decreases, the support gap between the top surfaces of two adjacent wire-drawing airbags will also be greatly reduced. Therefore, the wire-drawing airbag provided by the utility model can effectively solve the problem that there is a large support gap between the top surfaces of two adjacent airbags, resulting in poor sleep comfort.
[0043] Specifically, the airbag body 3 includes a top airbag sheet 301 located above the internal space, a bottom airbag sheet 302 located below the internal space, and an airbag side surround 303 connecting the top airbag sheet 301 and the bottom airbag sheet 302. The top airbag sheet 301, the bottom airbag sheet 302, and the airbag side surround 303 can all be made of TPU (thermoplastic polyurethane elastomer rubber) material.
[0044] The internal pulling structure 4 includes a plurality of horizontal partitions arranged at intervals from top to bottom, and the edge positions of the horizontal partitions are connected to the airbag side surround 303. After the internal space is inflated, the horizontal partitions will tighten the walls of the airbag side surround 303, limit the lateral arching of the walls of the airbag side surround 303, and greatly reduce the degree of outward expansion deformation of the airbag side surround 303, thereby making the sides of two adjacent wire-drawing airbags more fitting.
[0045] A number of longitudinal wires 402 are provided between two adjacent transverse partitions. After the inner space of the bladder is inflated, the longitudinal wires 402 will tighten the top bladder sheet 301 and the bottom bladder sheet 302, restricting the upward arching of the top bladder sheet 301 and the downward arching of the bottom bladder sheet 302, significantly reducing the degree of outward expansion deformation of the top bladder sheet 301 and the bottom bladder sheet 302, and thus making the top surfaces of two adjacent wire bladders fit more closely and making the bottom surfaces of two adjacent wire bladders fit more closely.
[0046] Optionally, each of the transverse partitions divides the inner space of the bladder into a number of partition spaces arranged from top to bottom. Each of the transverse partitions at the middle position (hereinafter referred to as "middle transverse partition 401a") is provided with a hollowed-out area communicating with the adjacent two partition spaces. The bladder side wall 303 and / or the bottom bladder sheet 302 is provided with an air inlet / outlet for inflating and deflating, which is communicated with any one of the partition spaces. By performing the inflating and deflating operation through the air inlet / outlet, the partition spaces in the inner space of the bladder can be inflated and deflated, and thus the support air pressure of the wire bladder can be changed.
[0047] In this embodiment, each of the middle transverse partitions 401a includes two textile fabrics 4011 that are bonded and fixed to each other; the edge position of the transverse partition is adhesively connected to the bladder side wall 303. The textile fabric 4011 itself is a breathable structure, so it belongs to a structure with a hollowed-out area by itself and does not require an additional air hole to be provided.
[0048] Further, the longitudinal wire 402 is a nylon wire, and the textile fabric 4011 is woven and connected with the corresponding longitudinal wire 402.
[0049] In this embodiment, the top bladder sheet 301 and / or the top bladder sheet 301 is adhesively connected or heat-pressed to the corresponding transverse partition at the end position (hereinafter referred to as "end transverse partition 401b"). Both the top bladder sheet 301 and the bottom bladder sheet 302 are heat-pressed to the bladder side wall 303. Optionally, the end transverse partition 401b can be a double-layer textile fabric 4011 structure or a single-layer textile fabric 4011 structure, and the present utility model does not limit this.
[0050] The production steps of the wire bladder provided in this embodiment are as follows:
[0051] ① When using nylon wires to weave the textile fabric 4011, one end of a number of nylon wires is made into a free end, and thus the textile fabric 4011 with longitudinal wires 402 can be obtained through the weaving process; then the nylon wires with free ends are added to the weaving process of another textile fabric 4011, and thus the two textile fabrics 4011 can be connected through the longitudinal wires 402;
[0052] ②Bond the textile fabrics 4011 with longitudinal draw wires 402 together in sequence to obtain the inner draw structure 4;
[0053] ③Then, bond and fix the edge positions of each of the transverse partitions to the inner side of the airbag side wall 303 to complete the fixing operation of the inner draw structure 4 and the airbag side wall 303;
[0054] ④Paste or hot-press and fix the middle position of the top airbag sheet 301 to the top end transverse partition 401b, and paste or hot-press and fix the middle position of the bottom airbag sheet 302 to the bottom end transverse partition 401b;
[0055] ⑤Hot-press and fix the edge position of the top airbag sheet 301 to the upper edge of the airbag side wall 303, and hot-press and fix the edge position of the bottom airbag sheet 302 to the lower edge of the airbag side wall 303, thereby completing the fixing operation of the entire draw wire airbag.
[0056] In summary, the draw wire airbag and the airbag mattress provided in this embodiment have the following advantages:
[0057] ①An inner draw structure 4 is arranged inside the airbag body 3 to tighten the walls of the space inside the airbag, restricting the outward arching of the surfaces of the airbag body 3, greatly reducing the degree of outward expansion deformation of the airbag body 3, and thus effectively solving the problem that there is a large support gap between the top surfaces of two adjacent airbags, resulting in poor sleep comfort;
[0058] ②The longitudinal draw wires 402 and the transverse partitions are woven and connected, with strong connection reliability and not easily separable.
[0059] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby.
