Description

Technical Field

[0001] This application relates to the technical field of inflatable portable air cushions, specifically to a portable inflatable seat back and seat. Background Technology

[0002] Seats are commonly used in homes, offices, or vehicles for leaning and sitting. Currently, to improve comfort, many seats use a separate backrest. These backrests typically consist of a fixed-volume outer cover and internal filling. They are relatively heavy and not easy to carry, and their hard texture can cause discomfort with prolonged use. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, this application provides a portable inflatable seat back that is equipped with multiple airbags, which can distribute the force to avoid damage to the airbags, and can also be inflated, deflated, stored and folded.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a portable inflatable seat back, the structure of which includes a support pad, a plurality of adjacent airbags are provided on the support pad, the plurality of airbags are connected to each other through air channels, and the air channels are connected to the inflation nozzle; a fixing ring is also provided on the support pad, the fixing ring being used to connect to the seat back.

[0005] Using the above structure, this application provides an inflatable seat back. When leaning against the back is needed, the airbag is inflated through the inflation nozzle to form a backrest, thus providing effective support for the back. When not leaning against the back, the air in the airbag can be expelled, allowing the entire portable inflatable seat back to be stored and rolled up for easy carrying, minimal space occupation, and light weight, making it suitable for various occasions. Furthermore, this application places the airbag on a support pad, with the airbag and support pad fixedly connected. When inflated, the support pad provides significant support to the airbag. Good support prevents significant deformation and maintains effective back support. Furthermore, the included retaining ring connects the entire portable inflatable seat back to the chair back, preventing shifting during leaning and maintaining stability. Most importantly, this application features multiple adjacent airbags, forming independent airbag structures on the support pad surface. This disperses the force on the airbags, reducing the risk of damage. In contrast, a single airbag covering the support pad surface would concentrate the force, making it more prone to damage.

[0006] Furthermore, airbags are provided on both sides of the support pad that are opposite each other in the thickness direction, and the oppositely arranged airbags are symmetrical to each other. With this structure, the inflatable backrest can be evenly supported from front to back, and the double airbag structure that is stacked in the thickness direction can further enhance the support for the back and the stability and comfort of leaning against it.

[0007] Furthermore, the support pads between the airbags arranged opposite each other in the thickness direction of the support pads are provided with air holes, which penetrate along the thickness direction of the support pads to connect with the airbags on both sides; in this way, during the inflation process, the gas from the air passage can be transferred from one side of the airbag to the other side to realize the filling action of the oppositely arranged airbags.

[0008] Furthermore, at least one fixing ring is provided, extending along the width direction of the support pad and forming a gap with the airbag on the support pad; with this structure, the chair back can be fixed by the at least one fixing ring.

[0009] Furthermore, two fixing rings are provided, and the two fixing rings are arranged opposite each other along the thickness direction of the support pad; with this structure, it is not necessary to identify the front or back during the picking process, and the connection with the chair back can be achieved from either side.

[0010] Furthermore, the retaining ring is an elastic band. This structure allows for easy elastic stretching and contraction, forming a strong elastic connection with the chair back.

[0011] Furthermore, the fixing ring is located near one end along the length of the support pad, and the width and length of the support pad are adapted to the width and length of the chair back. This structure facilitates quick and easy connection and fixation with the chair back, and the mutually compatible dimensions ensure that the portable inflatable seat back completely covers the chair back, thus providing comprehensive support.

[0012] Furthermore, the multiple airbags are neatly arranged along the length and width of the support pad, and the spacing between each pair of adjacent airbags is equal. With this structure, when leaning against the airbag, a more balanced force can be achieved, avoiding force concentration and improving the service life of the airbag.

[0013] This application also provides a seat that includes the portable inflatable seat back described above. The seat with the backrest is more comfortable and gentle to lean on, and can distribute the leaning force to different airbag structures to achieve stable support. It is also less likely to cause the backrest to be damaged due to concentrated force, thus extending the service life of the backrest. When not in use, the air in the airbags can be emptied, allowing it to be folded and stored for easy carrying and is also lightweight. Attached Figure Description

The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] As attached Figure 1-5As shown, the technical solution adopted in this application is: a portable inflatable seat backrest, the structure of which includes a support pad 1, on which multiple adjacent airbags 2 are disposed, the multiple airbags 2 being interconnected through air passages, the air passages being connected to inflation nozzles 3; the support pad 1 is also provided with a fixing ring 4, the fixing ring 4 being used to connect to the seat backrest; specifically, the support pad 1 is an integral piece of sheet material, which has a certain rigidity to support the airbags and the back of the human body, but its material can also be... The system allows for folding and rebound; the airbag 2 is made of non-breathable canvas or plastic, silicone, or other materials, and can be repeatedly inflated and deflated without damage or leakage; the air passage is located on the support pad 1 and can communicate with each airbag 2, and gas can be injected into each airbag cavity through the inflation nozzle 3 using tools such as an air pump to lift the airbag 2; the fixing ring 4 has a certain elastic deformation force, can be stretched and restored, and fits with the seat back to achieve a fitting connection between the entire inflatable backrest and the seat back.

[0022] Using the above structure, this application provides an inflatable and deflated seat back. When leaning against the back is needed, the airbag 2 is inflated through the inflation nozzle 3 to form a backrest, thus providing effective support for the back. When not leaning against the back, the air in the airbag 2 can be expelled, allowing the entire portable inflatable seat back to be stored and rolled up for easy carrying, minimal space occupation, and light weight, making it suitable for various occasions. Furthermore, this application places the airbag 2 on the support pad 1, with the airbag 2 and the support pad 1 fixedly connected. When inflated, the support pad 1 provides excellent support for the airbag 2, preventing significant deformation and maintaining its position. It provides effective back support; furthermore, the fixed ring 4 connects the entire portable inflatable seat back to the chair back, preventing displacement during leaning and maintaining the stability of the leaning position; moreover, most importantly, this application features multiple adjacent airbag 2 structures, forming multiple independent airbag 2 structures on the surface of each side of the support pad 1, which disperses the force on the airbags, preventing force concentration and thus reducing the risk of damage to the airbags 2; whereas if a single airbag 2 covered the surface of the support pad 1, the force would be more concentrated, making it more prone to damage; the structure of this application can extend the service life of the entire backrest.

[0023] As attached Figure 2-5As shown, airbags 2 are provided on both sides of the support pad 1 that are opposite each other in the thickness direction, and the oppositely arranged airbags 2 are symmetrical to each other; that is, a pair of airbags 2 are symmetrically arranged along the thickness direction of the support pad 1, and each pair of oppositely arranged airbags 2 has the same size and is arranged corresponding to each other to achieve stable support; with this structure, balanced support can be achieved from front to back, and the double airbags 2 that are stacked together in the thickness direction can further enhance the support for the back and the stability of leaning.

[0024] As attached Figure 3 As shown, the support pad 1 of this application is provided with air holes 101 between the airbags 2 arranged opposite each other in the thickness direction. The air holes 101 penetrate along the thickness direction of the support pad 1 to connect with the airbags 2 on both sides. That is, the airbags 2 on both sides are connected to each other through the air holes 101. In this way, during the inflation process, the gas from the air passage can be transferred from one side airbag 2 to the other side airbag 2 to realize the filling action of the oppositely arranged airbags 2. In addition, the pair of airbags 2 arranged opposite each other in the thickness direction of the support pad 1 can also be not connected to each other. Instead, the gas is divided into two airflows through the inflation nozzle 3. One airflow enters into the multiple airbags 2 arranged on one side surface of the support pad 1 in the thickness direction, and the other airflow flows into the multiple airbags 2 arranged on the other side surface of the support pad 1 in the thickness direction. In this way, it is not necessary to provide the air hole 101 structure on the support pad 1. It is only necessary to provide air passages on both sides surface of the support pad 1 in the thickness direction, which are connected to the multiple airbags 2 on each side and the inflation nozzle 3.

[0025] As attached Figure 1 , 3 As shown in Figure 5, at least one fixing ring 4 is provided in this application, which extends along the width direction of the support pad 1 and forms a gap with the airbag 2 on the support pad 1; that is, the length extension direction of the fixing ring 4 is laterally extended and fits into the backrest, and a gap is formed between it and the airbag 2 for the backrest to be accommodated; with this structure, the fixing ring 4 can be fitted onto the backrest to form a fixation.

[0026] As attached Figure 2 As shown, the fixing ring 4 described in this application is provided in two parts. The two fixing rings 4 are arranged opposite each other along the thickness direction of the support pad 1, that is, they are symmetrically arranged front and back along the thickness direction of the support pad 1. With this structure, it is not necessary to identify the front and back during the picking process, and the connection with the chair back can be achieved in either case. Alternatively, one or a pair of fixing rings can be provided at both ends of the support pad 1 along its length direction. In this way, when the inflatable backrest is fitted onto the chair back, the two points are fitted together, ensuring that the inflatable backrest is not easy to shift, and providing a more stable support for the back of the human body.

[0027] As an example, the fixing ring 4 described in this application is an elastic band, that is, made of elastic band material with elastic deformation and recovery force, and has a certain extension width, forming a flat wide-band fixing ring structure, which can better fit the line of sight between the fixing ring and the chair back; with this structure, it can be easily stretched and contracted elastically, and can form a firm elastic connection with the chair back.

[0028] As attached Figure 1-5 As shown, the fixing ring 4 described in this application is located near one end of the support pad 1 along its length, and the width and length of the support pad 4 are adapted to the width and length of the chair back; that is, the fixing ring 4 is located near one end of the support pad 1 along its length rather than in the middle, and the area of ​​the support pad 1 is not less than the area of ​​the chair back it fits into; with this structure, it is convenient to quickly and easily connect and fix with the chair back, and the mutually adapted dimensions can ensure that the portable inflatable seat back completely covers the chair back, thereby providing comprehensive support.

[0029] As attached Figure 1-2 As shown, the multiple airbags 3 described in this application are neatly arranged along the length and width of the support pad 1, and the spacing between each pair of adjacent airbags 2 is equal; that is, multiple orderly arranged airbag structures 2 are provided on the two surfaces of the support pad 1 that are opposite each other in the thickness direction; with this structure, when leaning against the airbag 2, a more balanced force can be achieved, avoiding force concentration and improving the service life of the airbag 2.

[0030] As an example, this application also provides a seat that includes the portable inflatable seat back described above. The seat with the backrest is more comfortable and gentle to lean on, and the leaning force can be distributed to the structure of different airbags 2 to achieve stable support. It is also less likely to cause the backrest to be damaged due to concentrated force, thus extending the service life of the backrest. When not in use, the gas in the airbags 2 can be emptied, allowing it to be folded and stored for easy carrying and is also lightweight.

[0031] The portable inflatable seat back of this application can be integrally injection molded using processes such as injection molding, so that the support pad and airbag form a complete integral structure, thereby improving the overall sturdiness.

[0032] This portable inflatable seat back can be easily fitted onto the back of a seat using a solid ring 4. It features an inflatable airbag structure, making it lightweight, easy to inflate and deflate, and convenient to store and carry. Furthermore, the regularly arranged multiple airbags 2 on the support pad 1 provide excellent back support, and the force of leaning is distributed across the different airbags 2, preventing concentrated stress. This effectively protects the airbags 2 from damage, extending their lifespan, while providing stable and gentle back support, reducing fatigue even after prolonged use.
