[0028] The present invention will be further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of the present invention, it should be noted that, for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating directions and positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0032] An inflatable jacket, such as Figure 1-Figure 3 As shown, the garment comprises a garment body 10, an airbag 20, and an automatic inflation assembly 30. The garment body 10 has an interlayer space 11 therein; the airbag 20 is accommodated in the interlayer space 11 of the garment body 10, and includes a back-mounted bag portion 21 located on the back of the garment body 10 and a front-mounted bag portion 22 located on the front chest of the garment body 10; the automatic inflation assembly 30 is fixed to the back of the garment body 10 and is in communication with the airbag 20. When the automatic inflation assembly 30 comes into contact with water, it inflates the back-mounted bag portion 21 and the front-mounted bag portion 22.

[0033] In other words, the automatic inflation assembly 30 located on the back of the garment body 10 automatically inflates the airbag 20 when the user falls into the water. This airbag 20 then provides buoyancy to the user, allowing them to rescue themselves while awaiting rescue, thereby increasing the chance of survival for those who accidentally fall into the water. In at least one embodiment, the buoyancy provided by the inflated airbag 20 is no less than 80N.

[0034] It is understood that even if the user is unconscious or injured when falling into the water, the automatic inflation assembly 30 of this embodiment can automatically inflate the airbag 20 when exposed to water. Compared to inflation devices that require manual activation, the automatic inflation assembly 30 of this embodiment can improve the reliability of the inflatable jacket.

[0035] In some embodiments, as Figure 5 and Figure 6 As shown, the automatic inflation assembly 30 includes a trigger 32, a gas cylinder 33, and a first connecting tube 31. When exposed to water, the trigger 32 activates the gas cylinder 33, which then communicates with the airbag 20 via the first connecting tube 31, allowing the gas in the gas cylinder 33 to enter the back-mounted bladder portion 21 and the front-mounted bladder portion 22. In one embodiment, the trigger 32 is a water-soluble tablet trigger 32. The water-soluble tablet of the water-soluble tablet trigger 32 dissolves when exposed to water, thereby triggering the gas cylinder 33 to communicate with the first connecting tube 31, allowing the gas in the gas cylinder 33 to be inflated into the airbag 20.

[0036] In at least one embodiment, Figure 5 As shown, the automatic inflation component 30 is connected to the back bag portion 21 of the airbag 20 through the first connecting tube 31, which is beneficial to reducing the length of the first connecting tube 31, thereby reducing the space occupied by the first connecting tube 31 and improving the inflation efficiency.

[0037] In some embodiments, the volume of the front bladder 22 is greater than or equal to the volume of the back bladder 21. This ensures that, when inflated, the buoyancy provided by the front bladder 22 is greater than or equal to the buoyancy provided by the back bladder 21. This helps keep the user's face upward and out of the water, thereby preventing secondary choking and reducing the risk of drowning. In at least one embodiment, the buoyancy provided by the front bladder 22 is 1.5 to 2.5 times that provided by the back bladder 21.

[0038] In some embodiments, as Figure 2 and Figure 5 As shown, the lower end of the front bladder portion 22 extends and expands toward the side waist of the garment body 10. In other words, the front bladder portion 22 of the airbag 20 is located in front of the chest and near the side waist, which helps improve the airbag 20's wrapping and support for the body, making the buoyancy provided by the airbag 20 more evenly distributed and more ergonomic. Furthermore, the larger curvature of the lower end of the front bladder portion 22 helps improve the airbag 20's resistance to pressure, thereby reducing the risk of cracks in the airbag 20 after inflation.

[0039] It is worth mentioning that the lower end of the front bag portion 22 extends and expands toward the side waist of the garment body 10 , which also serves to increase the volume of the front bag portion 22 , which is conducive to making the buoyancy provided by the front bag portion 22 greater than or equal to the buoyancy provided by the back bag portion 21 .

[0040] In some embodiments, as Figure 5 As shown, the airbag 20 is integrally formed so that the back bag portion 21 and the front bag portion 22 are connected, thereby reducing the number of connecting pipes, which is beneficial to avoid the user being hurt by the setting of too many connecting pipes, thereby improving the comfort of the inflatable jacket.

[0041] In at least one embodiment, Figure 2 、 Figure 3 and Figure 5 As shown, the connection between the back-mounted bladder 21 and the front-mounted bladder 22 is located at the shoulder of the garment body 10, meaning that the airbag 20 is generally U-shaped. It is understood that the two ends of the back-mounted bladder 21 bypass the shoulder of the garment body 10 and connect to a front-mounted bladder 22. This allows for a wider connection between the back-mounted bladder 21 and the front-mounted bladder 22, facilitating air flow and improving the efficiency of inflating the airbag 20. It is worth noting that the location of the connection at the shoulder minimizes the impact of the airbag 20 on the user's arm movements, making it easier for the user to paddle for self-rescue or perform other maneuvers.

[0042] It is worth mentioning that in other embodiments, the back-mounted bladder portion 21 and the front-mounted bladder portion 22 may be formed separately and connected via a connecting tube. In other embodiments, the back-mounted bladder portion 21 and the front-mounted bladder portion 22 may also be formed separately and independently of each other, each connected to the automatic inflation assembly 30. This application does not impose any specific limitations on this.

[0043] In some embodiments, as Figure 1 As shown, the jacket body 10 includes an outer layer 13 and an inner lining 14 arranged from the outside to the inside, with an interlayer space 11 formed between the outer layer 13 and the inner lining 14 to accommodate the airbag 20. It can be understood that the inner lining 14 prevents the airbag 20 from directly contacting the human body, which is conducive to improving the comfort of the inflatable jacket.

[0044] In at least one embodiment, the lining 14 has a slit, so that the interlayer space 11 is connected to the outside world, and the airbag 20 and the automatic inflation component 30 are detachably connected, so that the airbag 20 can be taken out through the slit, so as to facilitate the installation and replacement of the airbag 20, thereby improving the reusability of the inflatable jacket.

[0045] It is worth mentioning that the slit is provided with a zipper, adhesive tape or other connectors to facilitate closing the slit and making the lining 14 smoother. The airbag 20 can be detachably connected to the garment body 10 by means of snaps, laces or buttons, which helps to prevent the airbag 20 from moving.

[0046] Furthermore, the automatic inflation component 30 is detachably connected to the garment body 10 , so that before cleaning the garment body 10 , the automatic inflation component 30 and the airbag 20 can be removed for easy cleaning.

[0047] In at least one embodiment, Figure 9 and Figure 10As shown, the jacket body 10 also includes a water barrier 15 for shielding the automatic inflation assembly 30. The water barrier 15 is connected to the outer side of the back of the outer layer 13 to form a downward-facing accommodating space 151. The automatic inflation assembly 30 is located within the accommodating space 151. It is understood that the water barrier 15 is waterproof, which helps prevent the automatic inflation assembly 30 from contacting liquid and causing the trigger 32 to be accidentally triggered. This reduces the risk of the airbag 20 accidentally inflating when it is not needed, and helps improve the reliability of the inflatable jacket. If the user accidentally falls into the water, water can enter the accommodating space 151 through the opening below the accommodating space 151, triggering the automatic inflation assembly 30 to inflate the airbag 20. The airbag 20 then provides buoyancy to the user, helping the user to save themselves or wait for rescue.

[0048] In at least one embodiment, the upper side and left and right side edges of the water baffle 15 are sealed or nearly sealed to the outer layer 13 to prevent liquid from entering the accommodating space 151 from the upper side and left and right sides of the water baffle 15 and triggering the automatic inflation assembly 30, thereby improving the rainproof performance of the inflatable jacket. Furthermore, the lower side edge of the water baffle 15 is non-sealed to the outer layer 13, for example, adhesive tape, buttons, snaps, etc. are arranged at intervals along the extension direction of the lower side edge. This not only facilitates the entry of water from the lower side edge and the outer side edge into the accommodating space 151 to trigger the automatic inflation assembly 30 if the user falls into the water, but also helps prevent the lower side edge of the water baffle 15 from turning outward or tilting under normal use, thereby ensuring a closer fit between the water baffle 15 and the outer layer 13.

[0049] In at least one embodiment, Figure 10 As shown, the lower side of the water retaining plate 15 extends to the armpit of the jacket body 10, and the automatic inflation component 30 is installed near the neck of the outer layer 13, which helps to reduce the risk of the inflation component getting wet. At the same time, when the user is wearing a backpack, the protruding automatic inflation component 30 is prevented from interfering with the backpack, which helps to improve the comfort of the inflatable jacket.

[0050] In some embodiments, as Figure 4 and Figure 5 As shown, the garment body 10 further comprises a storage pocket 12 and an auxiliary inflatable component 40 accommodated in the storage pocket 12. The auxiliary inflatable component 40 comprises an adjusting member 42 and a second connecting pipe 41. Figure 7 As shown, the adjusting member 42 is connected to the airbag 20 through the second connecting tube 41 , and the adjusting member 42 is adapted to switch between a closed position and an open position so as to close the second connecting tube 41 or connect it to the outside.

[0051] It is understood that when the adjustment member 42 is in the open position, the second connecting tube 41 is connected to the outside world, allowing the user to blow air into the airbag 20 through the second connecting tube 41 to replenish the gas in the airbag 20, thereby improving the reliability of the inflatable jacket. Alternatively, the user can deflate the airbag 20 through the second connecting tube 41 to facilitate the release of the gas in the airbag 20 after rescue, thereby reducing the volume of the airbag 20, facilitating further transportation and treatment, and improving the convenience of use of the inflatable jacket. When the adjustment member 42 is in the closed position, the second connecting tube 41 is sealed, which helps prevent the gas in the airbag 20 from leaking out through the second connecting tube 41.

[0052] In at least one embodiment, the storage pocket 12 is located on the chest of the garment body 10, and the auxiliary inflatable assembly 40 is connected to the front bladder portion 22 of the airbag 20 via a second connecting tube 41. This helps reduce the length of the second connecting tube 41, thereby reducing the space occupied by the second connecting tube 41 and improving inflation / deflation efficiency. In addition, compared to a storage pocket 12 located at the bottom hem of the garment body 10, the storage pocket 12 in this embodiment is located closer to the top of the garment body 10. This helps keep the storage pocket 12 above the water surface if the user falls into the water, thereby reducing the risk of water entering the storage pocket 12 and the auxiliary inflatable assembly 40.

[0053] In some embodiments, as Figure 7 and Figure 8 As shown, the adjusting member 42 includes a connecting portion 421 and a knob portion 422. One end of the connecting portion 421 is sealed and connected to the second connecting tube 41, and the other end of the connecting portion 421 is relatively rotatably connected to the knob portion 422. By rotating the adjusting knob portion 422, the adjusting member 42 can be switched between the closed position and the open position.

[0054] It can be understood that compared with the use of a sealing cover, in which the opening and closing states of the adjusting member 42 are switched by plugging and pulling the sealing cover, the opening and closing states of the adjusting member 42 are switched by a rotating action in this embodiment, which is easier to operate. Especially when the user falls into the water, he is likely to sink and float with the water flow. Switching the opening and closing states of the adjusting member 42 by a rotating action is easier and has a higher success rate, thereby improving the convenience of the inflatable jacket when in use.

[0055] In at least one embodiment, the connection portion 421 and the knob portion 422 are inseparable, which helps prevent the second connecting tube 41 from remaining in communication with the outside world due to the separation of the knob portion 422 and the connection portion 421, thereby reducing the risk of gas in the airbag 20 accidentally leaking from the second connecting tube 41 and water entering the airbag 20 through the second connecting tube 41. Furthermore, the rotation angle of the knob portion 422 between the open position and the closed position does not exceed 180 degrees, thereby improving operational efficiency.

[0056] In some embodiments, the open position includes an air intake position and an air release position. When the adjustment member 42 is in the open position, the knob portion 422 is adapted to move axially relative to the connecting portion 421. Figure 8 As shown, the adjusting member 42 switches between an intake position and a deflation position, thereby allowing one-way intake or deflation of air into the airbag 20 through the adjusting member 42. That is, when the adjusting member 42 is in the intake position, gas can only enter the airbag 20 from the adjusting member 42 through the second connecting tube 41, but the gas in the airbag 20 cannot escape through the second connecting tube 41. This helps prevent gas in the airbag 20 from escaping through the adjusting member 42 during intervals between inflating by the user. When the adjusting member 42 is in the deflation position, gas in the airbag 20 is discharged through the second connecting tube 41 and the adjusting member 42, thereby reducing the volume of the airbag 20.

[0057] In at least one embodiment, when the knob portion 422 is axially away from the connecting portion 421, the adjusting member 42 is in the intake position; when the knob portion 422 is axially close to the connecting portion 421, the adjusting member 42 is in the exhaust position. Furthermore, the adjusting member 42 includes a reset member that maintains the knob portion 422 in the intake position. By pressing the knob portion 422 to overcome the resistance of the reset member, the knob portion 422 can be switched to the exhaust position, thereby reducing the risk of the adjusting member 42 accidentally being in the exhaust position and causing gas leakage from the airbag 20.

[0058] In some embodiments, as Figure 8 As shown, the knob portion 422 has a whistle structure 4221, so that the user can blow the whistle for help. In at least one embodiment, the sound emitted by the whistle structure 4221 is not less than 100 decibels.

[0059] In some embodiments, as Figure 1 As shown, the inflatable jacket also includes a safety belt 50 installed at the waist of the jacket body 10. The two ends of the safety belt 50 are suitable for buckling with each other, and the length of the safety belt 50 is suitable for adjustment so that the safety belt 50 is suitable for surrounding the waist of the user, which is beneficial for making the jacket body 10 and the airbag 20 fit the human body better, reducing the probability of the inflatable jacket being separated from the user in the event of falling into the water, and improving the reliability of the inflatable jacket.

[0060] It is worth noting that, during the rescue process, the safety belt 50 can be connected to the rescue belt 50 through a rope, a hook, etc., which is conducive to improving the feasibility of the rescue operation and improving the rescue efficiency. In at least one embodiment, the safety belt 50 can withstand a tension of 300kg.

[0061] In at least one embodiment, Figure 1As shown, a number of fixing plates 16 are provided at intervals on the inner side of the jacket body 10. The fixing plates 16 are suitable for forming an installation channel 161. The safety belt 50 passes through the installation channel 161 and is detachably connected to the jacket body 10 to facilitate subsequent replacement of the safety belt 50, thereby improving the reuse rate of the inflatable jacket.

[0062] Furthermore, the ends of the safety belt 50 and the inner side of the garment body 10 are respectively provided with matching connectors, such as adhesive tape, buckles, buttons, snaps, etc., so that the ends of the safety belt 50 can be detachably connected to the garment body 10. This helps prevent the safety belt 50 from sliding relative to the garment body 10, which would cause the ends of the safety belt 50 to be blocked by the fixing plate 16. Furthermore, when in use, the ends of the safety belt 50 can be separated from the garment body 10 to facilitate the buckling operation.

[0063] In another embodiment, the safety belt 50 is secured to the garment body 10 by stitching.

[0064] The above describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and description merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
