[0027] An air injection kit 1000 for clothing may include a plurality of air modules 100-1 and 100-2, an air injection module 200, and a connection module 300.

[0028] The plurality of air modules 100-1 and 100-2 may be attached to different areas of clothing, which correspond to different body parts of a clothing wearer. Air is injected into the air modules 100-1 and 100-2, and thus a warming effect and a cushion sense may be provided to the clothing wearer. For example, three air modules 100-1 and 100-2 may be provided, one thereof is attached to a back portion of a coat (e.g., a zip-up jumper) having a zipper in a center of a front side thereof, and the other two thereof are attached to both chest portions.

[0029] In the embodiment, each of the air modules 100-1 and 100-2 may be formed to have a certain size and may be configured in an outer shape suitable for an attachment portion of the clothing. That is, each of the air modules 100-1 and 100-2 may be designed according to a body portion of a user and a specific area of the clothing.

[0030] The air modules 100-1 and 100-2 may include a plurality of air accommodation parts 110 that accommodate the air therein. For example, the air modules 100-1 and 100-2 may include a first piece of fabric 10 and a second piece of fabric 20 arranged to face each other in at least one area, and the air accommodation part 110 may be formed between the first piece of fabric 10 and the second piece of fabric 20. In the air accommodation part 110, the air may be injected into or discharged from the air injection module 200.

[0031] In an embodiment, a polymer film coating layer having air impermeability may be formed on at least one area of the first piece of fabric 10 and the second piece of fabric 20. Therefore, the first piece of fabric 10 and the second piece of fabric 20 may perform a shielding function of preventing the air in the air accommodation part 110 from leaking to the outside and preventing the user from being exposed to external moisture, water, or wind.

[0032] The polymer film coating layer may be formed of at least one of polyurethane (PU), thermoplastic polyurethane (TPU), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), linear low density polyethylene (LLDPE), polyimide (PI), polycarbonate (PC), acrylic resin, and polystyrene (PS) or a combination thereof, and preferably, may be formed of at least one of polyurethane (PU), polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). However, the present application is not limited thereto.

[0033] At least one joining area 120 formed by joining the first piece of fabric 10 and the second piece of fabric 20 to each other and at least one non-joining area 130 formed by not joining the first piece of fabric 10 and the second piece of fabric 20 may be formed around the air accommodation part 110.

[0034] The joining area 120 may partition the air accommodation part 110 from another air accommodation part 110. For example, the polymer film coating layer may be formed on surfaces that face each other of the first piece of fabric 10 and the second piece of fabric 20, and the joining area 120 may be formed by heat-fusing at least areas of the first piece of fabric 10 and the second piece of fabric 20 with each other. That is, when the first piece of fabric 10 and the second piece of fabric 20 are heated and pressed, the polymer film coating layer may be melted, the first piece of fabric 10 and the second piece of fabric 20 may be joined to each other, and thus the joining area 120 may be formed. However, the present application is not limited thereto, and the polymer film coating layer may be variously modified, for example, may be formed only one surface of one of the first piece of fabric 10 and the second piece of fabric 20. Further, for example, the plurality of joining areas 120 may be formed to have a constant length and may be arranged at regular intervals from each other, but the present application is not limited thereto, and the joining areas 120 may have various intervals or lengths.

[0035] The non-joining area 130 may allow the air accommodation part 110 to air-communicate with another adjacent air accommodation part 110. For example, the non-joining area 130 may be formed between at least some of the plurality of joining areas 120. When the air is injected into the air modules 100-1 and 100-2 through the air injection module 200, the air may be sequentially or simultaneously transmitted to the plurality of air accommodation parts 110 through the non-joining area 130.

[0036] The air injection module 200 may be coupled to at least one of the air modules 100-1 and 100-2 and inject the air into the air modules 100-1 and 100-2. To this end, the air injection module 200 may be coupled to communicate with at least one of the plurality of air accommodation parts 110 formed in the air modules 100-1 and 100-2.

[0037] In the embodiment, the air injection module 200 may include an air injection part 210, a coupling part 220, and an extension tube 230.

[0038] The air injection part 210 may have an air passage formed therein to be opened or closed according to an operation of the user, and the air may be injected by the user. For example, a stopper for opening or closing the air passage may be formed in one area inside the air injection part 210, and the user may open the stopper by operating the air injection part 210 and then blow the air into one end of the air injection part 210. The air introduced into the air injection part 210 may be injected into the air modules 100-1 and 100-2 while passing through the extension tube 230 and the coupling part 220.

[0039] The coupling part 220 may be fixedly coupled to the first piece of fabric 10 or the second piece of fabric 20 to communicate with a first air accommodation part, which is one of the plurality of air accommodation parts 110 of the air modules 100-1 and 100-2.

[0040] In the embodiment, the coupling part 220 may include a junction 221 and protrusions 222 and 223.

[0041] As illustrated in FIG. 6, one surface of the junction 221 may be joined to one area of the first piece of fabric 10 or the second piece of fabric 20 forming an inner surface of the first air accommodation part. For example, a through hole having a certain size may be formed in the first piece of fabric 10 or the second piece of fabric 20, and one surface of the junction 221 may be joined to seal a circumference of the through hole inside the first air accommodation part. An air communication hole 225 for allowing the coupling part 220 to communicate with an inside of the first air accommodation part may be formed through a central portion of the junction 221.

[0042] The protrusions 222 and 223 may extend from a circumference of the air communication hole 225 formed in the junction 221 and may pass through the first piece of fabric 10 or the second piece of fabric 20 to protrude outward from the first air accommodation part. As insides of the protrusions 222 and 223 are connected to the air communication hole 225 of the junction 221, an air passage communicating with the inside of the first air accommodation part may be formed in the coupling part 220, and the extension tube 230 may be coupled to open ends of the protrusions 222 and 223.

[0043] The protrusions 222 and 223 may include the first area 222 extending in a first direction from the junction 221 toward an outside of the first air accommodation part, and the second area 223 extending from an end of the first area 222 in a second direction parallel to an outer surface of the first piece of fabric 10 or the second piece of fabric 20. Therefore, the protrusions 222 and 223 may be bent in an "L" shape.

[0044] The extension tube 230 may be coupled to the second area 223, and for stable coupling of the extension tube 230, a screw coupling portion 224 may be formed at one position of the second area 223.

[0045] The extension tube 230 may connect the coupling part 220 and the air injection part 210, and therefore, the air injected into the air injection part 210 may be delivered to the inside of the first air accommodation part. At least a portion of the extension tube 230 may be formed of a soft material to enable shape deformation, and a coupling cap 231 for coupling with the protrusions 222 and 223 may be provided at least one end of the extension tube 230. A screw thread corresponding to the screw coupling portion 224 of the protrusions 222 and 223 may be formed in an inner surface of the coupling cap 231.

[0046] The connection module 300 may be coupled to the air modules 100-1 and 100-2 at both ends thereof, respectively, to deliver the air injected through the air injection module 200 between the air modules 100-1 and 100-2.

[0047] For example, one end of the connection module 300 may be coupled to communicate with the first air accommodation part, which is one of the plurality of air accommodation parts 110 of the first air module 100-1, and the other end thereof may be coupled to communicate with a second air accommodation part, which is one of the plurality of air accommodation parts 110 of the second air module 100-2. When the air is injected into the air injection module 200 coupled to the first air module 100-1, the air may first inflate the plurality of air accommodation parts 110 formed in the first air module 100-1 and then pass through the connection module 300 and be delivered to the second air module 100-2, thereby inflating the plurality of air accommodation parts 110 of the second air module 100-2.

[0048] In the embodiment, the connection module 300 may include a first coupling part 310, a second coupling part 320, and a connection tube 330.

[0049] The first coupling part 310 and the second coupling part 320 may be fixedly coupled to the first piece of fabric 10 or the second piece of fabric 20 to communicate with the first air accommodation part, which is one of the plurality of air accommodation parts 110 of the first air module 100-1, and the second air accommodation part, which is one of the plurality of air accommodation parts 110 of the second air module 100-2. The first coupling part 310 and the second coupling part 320 may have the same structure.

[0050] In the embodiment, the first coupling part 310 and the second coupling part 320 may include junctions 311 and 312 and protrusions 312-313 and 322-323. In this case, the first coupling part 310 and the second coupling part 320 may be joined to one area of the first piece of fabric 10 or the second piece of fabric 20 in the same structure as the coupling part 220 of the air injection module 200 described with reference to FIG. 6.

[0051] For convenience of description, a description will be made below based on the first coupling part 310.

[0052] One surface of the junction 311 of the first coupling part 310 may be joined to one area of the first piece of fabric 10 or the second piece of fabric 20 forming the inner surface of the first air accommodation part of the first air module 100-1. For example, the through hole having a certain size may be formed in the first piece of fabric 10 or the second piece of fabric 20, and the one surface of the junction 311 may be joined to seal the circumference of the through hole inside the first air accommodation part. An air communication hole for allowing the first coupling part 310 to communicate with the inside of the first air accommodation part may be formed through a central portion of the junction 311.

[0053] The protrusions 312 and 313 of the first coupling part 310 may extend from a circumference of the air communication hole formed in the junction 311 and may pass through the first piece of fabric 10 or the second piece of fabric 20 to protrude outward from the first air accommodation part. As insides of the protrusions 312 and 313 are connected to the air communication hole of the junction 311, an air passage communicating with the inside of the first air accommodation part may be formed in the first coupling part 310, and the connection tube 330 may be coupled to open ends of the protrusions 312 and 313.

[0054] The protrusions 312 and 313 may include the first area 312 extending in a first direction from the junction 311 toward the outside of the first air accommodation part, and the second area 313 which extends from an end of the first area 312 in a second direction parallel to the outer surface of the first piece of fabric 10 or the second piece of fabric 20 and to which the connection tube 330 is coupled. Therefore, the protrusions 312 and 313 may be bent in an "L" shape.

[0055] As described above, the second coupling part 320 may be coupled to the second air accommodation part of the second air module 100-2 in the same structure as the first coupling part 310.

[0056] The extension tube 230 may connect the first coupling part 310 and the second coupling part 320, and therefore, the air may be delivered between the first air module 100-1 and the second air module 100-2.

[0057] At least a portion of the extension tube 230 may be formed of a soft material to enable shape deformation.

[0058] In the embodiment, at least portions of the second area 313 of the first coupling part 310 and the second area 323 of the second coupling part 320 are inserted into the connection tube 330 at both ends of the connection tube 330, and thus the connection tube 330 may be coupled to the first coupling part 310 and the second coupling part 320. In this case, the connection tube 330 may be detachably coupled so that the connection tube 330 may be separated from the first coupling part 310 and the second coupling part 320 by a predetermined external force or more.

[0062] In detail, the at least one air circulation hole 121 may be formed through the first piece of fabric 10 and the second piece of fabric 20 that form the joining area 120 and are joined to each other.

[0063] A problem that air does not circulates in a clothing area to which the air modules 100-1 and 100-2 are attached may be solved through the air circulation hole 121.

[0064] According to embodiments of the present application, air can be sequentially delivered between a plurality of air modules through a connection module, and thus various areas of clothing can be simultaneously inflated by one injection of air.

[0065] According to an embodiment of the present application, a structure of an air module can be designed to be suitable for a body portion of a user and a specific area of clothing, and the number of air modules can be varied according to characteristics of the clothing. Therefore, customized cushioning sense and functionality can be effectively provided to various body portions.
