Description

Technical Field

[0001] This utility model relates to the field of inflatable seats, and more particularly to an ergonomic inflatable seat that can support the human waist. Background Technology

[0002] In today's diverse seating market, inflatable chairs, with their portability, have successfully attracted a large number of consumers in unique usage scenarios such as camping, outdoor picnics, and temporary emergencies. They are lightweight, easy to carry, and can be quickly inflated, providing convenient seating options for people in various environments. However, when we delve deeper into the actual use of these chairs, we find many problems that urgently need to be addressed.

[0003] Currently, inflatable chairs on the market are mainly divided into two camps. One is products made primarily of PU material. PU material itself has a certain degree of flexibility, making the chair easy to store before inflation and conforming to the human body contour to some extent after inflation. However, its shortcomings are also quite significant. During inflation, even when fully inflated, the internal air pressure is difficult to reach the ideal value for supporting the human body. When the user sits down expectantly, they can clearly feel the chair quickly collapsing. This collapse means the user's body cannot receive stable and strong support, and a feeling of insecurity arises the moment they sit down. If this type of chair is used for a long time, the user's body has to frequently adjust their posture to maintain balance. Using this type of chair while working overtime in the office for several hours results in muscle soreness due to continuous tension, not only greatly reducing work efficiency but also seriously affecting the user's overall experience.

[0004] Another type is inflatable seats made of PVC space fabric. PVC space fabric has certain advantages in terms of strength and durability, and is not easily damaged during normal use. However, these seats have a major design flaw, completely ignoring the need for human support. They merely provide a simple flat surface for people to sit on, without any optimization for the complex curves of the human body or key pressure points. For example, on long-distance travel, passengers sitting in these PVC space fabric inflatable seats do not receive proper support for their lower back and back, remaining suspended or under uneven pressure for extended periods. After the journey, many passengers complain of lower back pain and stiff backs, and may even develop poor posture due to prolonged use, leading to more serious health problems such as scoliosis. Comfort is practically nonexistent.

[0005] In summary, neither PU nor PVC inflatable seats can meet consumers' diverse needs for comfort, health, and a good user experience. In today's pursuit of a high-quality life, people's requirements for seats have long surpassed simple seating functions; they now place greater emphasis on comfort and health. Therefore, developing a new type of inflatable seat that effectively addresses these shortcomings and incorporates ergonomic design has become an urgent need for the industry. Utility Model Content

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0038] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0039] Reference Appendix Figure 1 To be continued Figure 3 As shown, an ergonomic inflatable seat 1 of this application is illustrated. The ergonomic inflatable seat 1 includes a seat cushion 10, a support body 20, and a backrest 30. One end of the support body 20 is connected to the seat cushion 10, and the other end is connected to the backrest 30. When fully inflated, a support portion 80 is formed at the connection between the backrest 30 and the support body 20. The support portion 80 is located above the seat cushion 10 and supports the lumbar region when the user is seated. In other words, when fully inflated, the support portion 80 has high dimensional stability and rigidity, sufficient to support the lumbar region, allowing the lumbar muscles to relax, effectively reducing fatigue, protecting key force-generating parts of the body, and improving the overall comfort of the user. Furthermore, since the ergonomic inflatable seat 1 can be used by inflation, that is, when not in use, its volume can be reduced by deflation, facilitating movement and storage, greatly simplifying user operation. Meanwhile, the ergonomic inflatable seat 1 can change the firmness of the seat by adjusting the air pressure, so as to meet the personalized comfort needs of different users in different scenarios and greatly enhance the adaptability of the product.

[0040] Furthermore, taking the plane where the seat cushion 10 is located as a reference plane, the support body 20 is connected to the left end of the seat cushion 10 and forms an acute angle with the plane where the seat cushion 10 is located, that is, it tends towards the right end of the seat cushion 10 at an acute angle, so that the support body 20 is located above the seat cushion 10, and when a person sits on the seat cushion 10, the height of the end of the support body 20 relative to the seat cushion 10 is exactly at the waist position of the person. In particular, the connection angle between the support body 20 and the seat cushion 10 can be different. For example, depending on the age of the passenger, the support body 20 provides different lumbar support positions. We can set different angles to meet the needs of passengers of different age groups, so that the support body 20 can stably support the passenger's waist, effectively reduce the passenger's lumbar fatigue, and improve the overall comfort of the ergonomic inflatable seat 1.

[0041] One end of the backrest 30 is connected to the end of the support body 20, forming a support portion 80 at the connection. The plane of the backrest 30 forms an obtuse angle with the plane of the seat cushion 10, that is, the backrest 30 is located away from the right end of the seat cushion 10. The backrest 30 is inclined to support the back of the human body above the waist, that is, the support portion 80 supports the waist of the occupant, and the backrest 30 supports the back of the occupant, while providing stable support for the occupant. It can be understood that the height of the support portion 80 relative to the seat cushion 10 is exactly at the waist position of the human body, so that the support portion 80 stably supports the waist of the occupant, effectively reducing the occupant's waist fatigue and improving the overall comfort of the ergonomic inflatable seat 1.

[0042] The seat cushion 10, the support body 20, and the backrest 30 are preferably made of PVC space fabric. Those skilled in the art should understand that the ergonomic inflatable seat 1 can also be made of other materials, including but not limited to those listed above. (See attached document.) Figure 5As shown, the ergonomic inflatable seat 1 includes a front leather 100, a rear leather 200, and a connecting leather 300. The connecting leather 300 surrounds the front leather 100 and the rear leather 200 to form an air chamber 40 inside. The front leather 100 is provided with two first fold lines 101. Connecting the two first fold lines 101 forms the seat cushion 10 and a support back 400 including the backrest 30 and the support body 20. The rear leather 200 is provided with two second fold lines 202. Connecting the two second fold lines 202 makes the area of ​​the rear part of the support back 400 smaller than the area of ​​the front part of the support back 400. Connecting the two second fold lines 202 makes the lower part of the support back 400 form the support body 20, and the support part 80 is formed at the corresponding position of the front leather 100. The backrest 30 is formed above the support part 80. The ergonomic inflatable seat 1 uses PVC space fabric as raw material, which is lightweight and has excellent dimensional stability. After inflation, it not only has a smooth surface and uniform stress distribution, but also has high tensile strength, high tear strength and high rigidity, providing high compressive strength and toughness, making it durable and reducing the trouble of frequently replacing seats.

[0043] Furthermore, the air chamber 40 connects the seat cushion 10 with the support body 20 and the interior of the backrest 30. The seat cushion 10 also includes an inflation port 90, which is installed on the seat cushion 10. Inflation and deflating of the air chamber 40 are performed through the inflation port 90. A protective cover can also be provided on the inflation port 90 to prevent air leakage from the ergonomic inflatable seat 1. It is understood that through the inflation port 90 and the air chamber 40, the ergonomic inflatable seat 1 can adjust the firmness of the seat by regulating the air pressure, meeting the personalized comfort needs of different users in different scenarios, greatly enhancing the product's adaptability. At the same time, the ergonomic inflatable seat 1 has only one air chamber 40 and one inflation port 90, which greatly simplifies the operation process in actual use, allowing users to quickly complete inflation and enjoy a convenient experience.

[0044] The seat cushion 10 also includes a first anti-slip pad 71, which is installed on the upper surface of the seat cushion 10. The backrest 30 also includes a second anti-slip pad 72, which is installed on the front of the backrest 30. The area covered by the first anti-slip pad 71 and the second anti-slip pad 72 is exactly the maximum contact area when a passenger contacts the ergonomic inflatable seat 1 with the seat cushion 10 and the backrest 30. In other words, the first anti-slip pad 71 and the second anti-slip pad 72 can most effectively prevent slippage on the contact surfaces, which is especially important during outdoor activities.

[0045] In outdoor environments, ground conditions are complex and diverse, with slopes, damp grass, moss-covered rocks, and more readily available. When a person sits down, stands up, or adjusts their posture, their center of gravity easily shifts. Ordinary chair surfaces are often too smooth to provide sufficient friction. However, the ergonomic inflatable chair 1, equipped with the first anti-slip mat 71 and the second anti-slip mat 72, greatly increases the friction between the chair surface and the human body, effectively preventing accidental slips caused by uneven ground or body swaying, significantly reducing the risk of falls and injuries, and ensuring the user's safety. When changing outdoor gear or reaching for distant objects while seated on the ergonomic inflatable chair 1, the body needs to remain stable. The first anti-slip mat 71 and the second anti-slip mat 72 help the user maintain a relatively stable posture, preventing the body from unconsciously sliding due to the smooth chair surface, ensuring a more comfortable and safer sitting experience. Outdoor weather is unpredictable; the seat surface easily becomes slippery when wet in the rain, and may also become slippery under the hot sun. However, the first anti-slip mat 71 and the second anti-slip mat 72 maintain excellent anti-slip performance under all weather conditions, always providing reliable support for the user. They also reduce direct friction between the body and the seat, preventing scratches from zippers, buttons, and other hard objects on clothing, avoiding localized wear caused by frequent sliding, protecting the integrity and aesthetics of the ergonomic inflatable seat 1, and extending its service life. Furthermore, the first anti-slip mat 71 and the second anti-slip mat 72 are easy to clean. In outdoor environments, seats easily accumulate dust, mud, and other stains; even if the anti-slip mats get dirty, a simple wipe or rinse will restore them to cleanliness, much easier than cleaning the entire seat. Notably, the first anti-slip mat 71 and the second anti-slip mat 72 can be made of soft, elastic materials, providing additional cushioning while offering anti-slip properties, conforming to the body's curves to distribute pressure, and reducing discomfort from prolonged sitting.

[0046] The backrest 30 also includes a net pocket 31, which is installed on the back of the backrest 30. The net pocket 31 greatly enhances the practicality of the ergonomic inflatable seat 1. The net pocket 31 provides extra storage space, which can be used to store travel tools such as maps and compasses when camping outdoors; to store bait and fishing reels when fishing; and to store remote controls, magazines, etc. in the living room, making the environment tidier. The net pocket 31 is positioned close to the user, making it extremely convenient to retrieve items and saving search time. The net pocket 31 utilizes the unused space behind the backrest 30, without taking up additional floor or table space.

[0047] The ergonomic inflatable seat 1 also includes multiple D-rings 50, which are installed on both sides of the ergonomic inflatable seat 1 via D-ring connectors 51. The D-ring connectors 51 can distribute the pressure at the connection points of the D-rings 50, reducing stress concentration on the D-rings under load, preventing damage to the ergonomic inflatable seat 1 under stress, and enhancing the durability of the ergonomic inflatable seat 1. The D-rings 50 have excellent practicality. For example, in outdoor camping scenarios, the D-rings 50 can be used to hang camping lights, instantly illuminating the area around the tent and providing ample lighting; when resting, small backpacks, water bottles, etc., can be hung on the D-rings 50, freeing up the hands. Because the D-rings 50 are installed on both sides of the ergonomic inflatable seat 1, users can easily reach and operate them, making them more convenient than placing items far away. Moreover, the D-rings 50 cleverly utilize the unused space on both sides of the ergonomic inflatable seat 1 without taking up extra space, making them useful in campsites with limited space or in outdoor areas where items are easily lost. At the same time, it also enhances the functionality of the ergonomic inflatable seat 1, improves its overall practicality and product competitiveness, adds a unique industrial aesthetic to the ergonomic inflatable seat 1, and complements the surrounding environment.

[0048] The ergonomic inflatable seat 1 also includes a handle 60, which is mounted to the top of the backrest 30 via a pair of handle connectors 61. This allows the user to move the ergonomic inflatable seat 1 using the handle 60. The handle connectors 61 can distribute the pressure at the connection point of the handle 60, reduce stress concentration on the handle 60 when under force, prevent the ergonomic inflatable seat 1 from breaking when the handle 60 is under force, and enhance the durability of the ergonomic inflatable seat 1.

[0049] Reference Appendix Figure 4This is a comparative diagram of the ergonomic inflatable seat 1 and the existing inflatable seat 2. It is understood that the existing inflatable seat 2 has a flat backrest, leaving the lumbar region unsupported when the passenger sits on it. Although the back is supported, the lumbar muscles remain tense, preventing them from relaxing. Prolonged sitting in this condition can easily lead to discomfort, especially in unpredictable outdoor environments, causing fatigue. Referring to the ergonomic inflatable seat 1 of this application, the support portion 80 is positioned at the lumbar level relative to the seat cushion 10, providing stable support for the lumbar region and allowing the lumbar muscles to relax, effectively reducing lumbar fatigue. It is also understandable that the backrest of the existing inflatable seat 2 is flat and back, causing the occupant's center of gravity to shift backward, which further aggravates the discomfort of sitting for a long time. However, the support part 80 of the ergonomic inflatable seat 1 keeps the occupant's center of gravity above the seat cushion 10, keeping the center of gravity in the middle position, so that the ergonomic inflatable seat 1 can further stably support the occupant.

[0050] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
