Background of the Disclosure

[0003] With the development of society and the improvement of people's living standards, people have higher requirements for the quality of life. Ordinary palm mattresses, latex mattresses, spring mattresses, etc. can no longer meet people's needs. Inflatable products such as inflatable bodies are increasing in popularity because they are easy to carry, easy to collect, and have strong flexibility and elasticity, are not easy to deform, and have good comfort.

[0004] However, current inflatable bodies cannot adjust its height upon demand. While current inflatable bodies can be used for laying down, they cannot be used for lounging at an angle, e.g., cannot be leaned backwards. There is no corresponding back support structure for people sitting on the inflatable body, which can easily cause human fatigue.

[0005] In response to this problem, Chinese Patent No. 202653667U discloses an adjustable inflatable mattress, which comprises at least one ventilated main airbag, at least one independent auxiliary airbag, and an electric air pump. The ventilated main airbag comprises at least three independent ventilated air chambers, where each two adjacent breathable air chambers are separated by a tubular drawstring. The auxiliary airbag is located at the outside of the bottom of the ventilated air chamber. The disclosure comprises at least three overlapped triangular air chambers, where each two adjacent triangular air chambers are separated by a tubular drawstring and each triangular air chamber and each ventilated air chamber are equipped with at least one air nozzle. The air nozzles are all located on the same side of the corresponding air chamber and are connected with the electric air pump through air pipes. Although the disclosed adjustable inflatable mattress is capable of height adjustment, it requires multiple air chambers, and further needs to be equipped with specially shaped auxiliary airbags, which are triangle-shaped. The structure is complex and the production cost is high.

Detailed Description of the Embodiments

[0080] As shown in FIGS. 1-2, the present disclosure describes a support assembly 130, including an adjustable airbag 20 with a hard, i.e., rigid, support, which comprises an adjustable support frame 10, a fixing member, or fixing assembly 33, which may comprise fixing frame 30. The adjustable support frame 10 comprises a support frame body 11, which may be a U-shaped structure, with the open end of the U-shaped structure hinged with the fixing frame 30. The fixing frame 30 may be U- shaped. The open end of the U-shaped fixing frame 30 is hinged with the support frame body 11. The hinged relationship between the fixing frame 30 and the support frame body 11 is facilitated by a fixing assembly 33, which may include fasteners 60. [0081] An adjustable airbag 20 is coupled below the adjustable support frame 10, and, more particularly, between the support frame body 11 and the fixing frame 30. Specifically, the adjustable airbag 20 is coupled to the adjustable support frame 10, interchangeable here with support frame body 11, through a first flexible sheet 50, and the adjustable airbag 20 is further coupled to the fixing frame 30 through a second flexible sheet 50. The flexible sheet(s) 50 may be coupled to the adjustable support frame 10 (i.e., support frame body 11) and/or the fixing frame 30 via a plurality of loops 62 which extend from an edge of the flexible sheet(s) and slide over the frame of the corresponding component to couple said component to the flexible sheet 50. The flexible sheet(s) 50 may be coupled to the adjustable airbag 20 via welding, unitary manufacturing, adhesive, hook-and-loop, zipper, thread, or other acceptable coupling methods.

[0082] The present disclosure positions the adjustable support frame 10 on the adjustable airbag 20, and the adjustable support frame 10 hinges with the fixing frame 30. When the adjustable airbag 20 is inflated, the adjustable airbag 20 expands to push the adjustable support frame 10, with a first end of the adjustable support frame 10 using the fixing frame 30 as a fulcrum, so that the other end of the adjustable support frame 10 swings upward to form a support slope as described further herein. When the adjustable airbag 20 is in a deflated state, the adjustable support frame 10 folds the adjustable airbag 20 onto the fixing frame 30. As such, when the adjustable airbag 20 of the present disclosure is used for an inflatable body, a selected position of the inflatable body can be raised and lowered.

[0083] The adjustable airbag 20 of the present disclosure may be applied to an inflatable body 210, also interchangeable with, but not limited to, “inflatable bed”, where appropriate, as shown in FIGS. 3-5. The inflatable body 210 may include a first part 111, which may be generally associated with a head portion of the inflatable body 210, and a second part 112, which may be generally associated with a leg portion of the inflatable body 210. The first part 111 of the inflatable body 210 and the second part 112 of the inflatable body 210 are coupled with each other. The first part 111 of the inflatable body 210 and the second part 112 of the inflatable body 210 are in a swinging connection with each other so that the first part 111 and the second part 112 can be folded; that is, the corresponding surfaces of the first part 111 and the second part 112 can be folded together.

[0084] When applied to the inflatable body 210, the adjustable airbag 20 is placed under a head portion, or first part 111, of the inflatable body 210. As described above, when the adjustable airbag 20 is in the inflation state, the support frame body 11 and the fixing frame 30 open to a certain angle, so as to lift the first part 111 of the inflatable body 210 to a certain height and angle and, while inflated, continue to support the first part 111 at said height and angle, so that a user can sit or lounge on the inflatable body 210 with upper body support. As shown in FIGS. 6-7, when the adjustable airbag 20 is in the deflation state, the support frame body 11 folds the adjustable airbag 20 onto the fixing frame 30, and the height of the first part 111 of the inflatable body 210 is lowered, so that a user can lie generally flat on the inflatable body. The support frame body 11 further folds onto the fixing frame 30 and may generally nest within the fixing frame 30. In other words, the support frame body 11 plays a supporting role for the adjustable airbag 20 and the first part 111 of the inflatable body 210, while the adjustable airbag generally controls the opening angle of the adjustable support frame 10.

[0085] Inflation and deflation of the adjustable airbag 20 may be largely controlled via inflation/deflation port 64. In other words, adjustable airbag 20 may be inflated by introducing air or other fluid through inflation/deflation port 64 via a manual pump, automatic pump, or manually blowing air into the inflation port 64. Conversely, adjustable airbag 20 may be deflated by opening inflation/deflation port 64 to allow air or other fluid to exit the adjustable airbag naturally or via a manual pump or automatic pump.

[0086] While the adjustable airbag is illustrated throughout the figures as having a general pillow shape, adjusting the shape of the adjustable airbag 22 will not affect the function of the adjustable airbag 22 as described herein. For example, the shape of the adjustable airbag 22 may also be generally cylindrical, as illustrated in FIGS. 8-9, or another shape, such as triangular, rectangular, arcuate, etc.

[0087] Referring to FIGS. 10-11, another embodiment of the support assembly 130 is shown. The structure of the support assembly 130 as shown in FIGS. 10-11 is generally the same as that discussed above in relation to FIGS. 1-9 with the relevant differences described herein.

[0088] As shown, the fixing member, or fixing assembly 33, of the support assembly 130 comprises two fixing bases 41, which can be directly hinged with the open end of the adjustable support frame 10, i.e., support frame body 11, or can be hinged with the support frame body 11 through a pin shaft 42. In other words, the support frame body 11 may couple to each of the fixing bases 41 via a hinge-type fastener. In other embodiments, the support frame body 11 may couple to each of the fixing bases 41 via a pin shaft 42, which extends through and from a receiving member in a first fixing base 41, through a through-hole of a first branch of the support frame body 11, along the width of the support frame body and through a through-hole of a second branch of the support frame body 11, and through a receiving member in a second fixing base 41 to create a hinge-type relationship between the first fixing bases 41 and the support frame body 11. In some embodiments, the pin shaft 42 may be fixedly coupled to each of the fixing bases 41. [0089] Each fixing base 41 is fixedly coupled with the inflatable body 210 or a placement platform (not shown) of the inflatable body 210 as described further herein. In this way, when the adjustable airbag 20 is in the inflation state, the adjustable support frame 10 can present an inclined plane, i.e., open to a certain angle relative to an angle along which the inflatable body 210 lies, so as to lift the first part 111 of the inflatable body 210 to a certain height and angle and, while the adjustable airbag 20 is inflated, continue to support the first part 111 at said height and angle, so that a user can sit or lounge on the inflatable body 210 with upper body support. In other words, adjustable support frame 10 forms a backrest inclined plane on the inflatable body 210 similar to that described above and further herein. When the adjustable airbag 20 is in the deflation state, the support frame body 11 folds the adjustable airbag 20 and the height of the first part 111 of the inflatable body 210 is lowered, so that a user can lie generally flat on the inflatable body.

[0090] Referring to FIGS. 12-13, another embodiment of the support assembly 130 is shown. The structure of the support assembly 130 as shown in FIGS. 12-13 is generally the same as the support assembly 130 discussed above in relation to FIGS. 1-11 with the relevant differences described herein.

[0091] The adjustable support frame 10 comprises a support frame body 11 and a shaft sleeve 12 coupled to the support frame body 11. The fixing member, or fixing assembly 133, comprises two fixing bases 41 and a pin shaft 42 fixed between the two fixing bases 41. The shaft sleeve 12 may be positioned around the pin shaft 42 so that the shaft sleeve 12 can rotate about the pin shaft 42, thereby raising and lowering a position of the support frame body 11. In other words, the shaft sleeve 12 may be rotatably sleeved on the pin shaft 42. The support frame body 11 may be any shape. For example, as shown, the support frame body 11 may be two post-shaped extensions from the shaft sleeve 12. In other embodiments, the support frame body 11 may be U-shaped as disclosed above or may be another operative shape, such as triangular, rectangular, arcuate, etc. A support plate 13 may be coupled to the support frame body 11 to provide additional support to the adjustable airbag 20 and/or the inflatable body 210 when in use.

[0092] When the adjustable airbag 20 of the present disclosure is applied to the inflatable body 210, the adjustable airbag is placed under the first part 111 of the inflatable body 210. Each of the fixing bases 41 are coupled to the inflatable body 210 or coupled to a placement platform (not shown) of the inflatable body 210. In some embodiments, each of the fixing bases 41 may be fixedly coupled to the inflatable body 210 or the placement platform of the inflatable body 210.

[0093] When the airbag 20 is in the inflation state, the support frame body 11 can present an inclined plane, i.e., open to a certain angle relative to an angle along which the inflatable body 210 lies, so as to support the first part 111 of the inflatable body 210 to a certain height and angle, so that a user can sit or lounge on the inflatable body 210 with upper body support. When the adjustable airbag 20 is in the deflation state, the support frame body 11 folds the adjustable airbag 20, so that the height of the first part 111 of the inflatable body 210 is lowered, so that a user can lie generally flat on the inflatable body.

[0094] Referring to FIGS. 14-19, the present disclosure includes a multi-tier and multi-position adjustable inflatable body, which comprises an upper bed body 310, a lower bed body 320 and a support assembly 130 arranged on the upper bed body 310 and the lower bed body 320. The support assembly 130 is generally as shown in FIGS. 14-19 may generally be the same as any of the corresponding embodiments discussed above in relation to FIGS. 1-13 with the relevant differences described herein. [0095] The middle part of the upper bed body 310 is connected with the lower bed body 320, and the upper bed body 310 is divided into a first part 111 and a second part 112 according to the middle connection position; the support assembly 130 is located beneath the first part 111 of the upper bed body 310, which comprises an adjustable support frame 10, a first adjustable airbag 20 and a fixing assembly 133. The first adjustable airbag 20 is coupled to the adjustable support frame 10, wherein one end of the adjustable support frame 10 is coupled to the fixing assembly 133 in a hinged relationship, and the fixing assembly 133 is arranged on the lower bed 320. When the fixing assembly 133 includes a fixing frame 30 as described above, the contact area between the fixing frame 30 and the lower bed body 320 is relatively large to facilitate smooth movement of the adjustable support frame 10. The fixing frame 30 may be fixedly coupled to the lower bed body 320 or otherwise coupled to the lower bed body 320.

[0096] In practical application, the first part 111 of the upper bed body 310 corresponds to the upper part of the human body, and the second part 112 of the upper bed body 310 corresponds to the lower part of the human body. When a user desires to sit or lounge at an inclined angle, the first adjustable airbag 20 is inflated. The first adjustable airbag 20 pushes the adjustable support frame 10 so that the adjustable support frame 10 swings upward relative to the fixing assembly 133, so that the first part 111 of the upper body 310 rises relative to the lower body 320 and forms an intersection angle with the first part 111, so as to realize the height and/or incline adjustment of the inflatable body and meet the user's desired incline. When the first adjustable airbag 20 is deflated, the adjustable support frame 10 folds the adjustable airbag 20 onto the lower bed body 320. At this time, the inflatable body 210 is lowered so that user(s) can lie generally flat.

[0097] In order to further improve the comfort of the user when sitting, lounging, or lying down, the inflatable body 210 of the present disclosure may further comprise a second adjustable airbag 340, which is arranged between the second part

112 of the upper bed body 310 and the lower bed body 320, and positioned distally of the connection point between the first part upper bed body 310 and the lower bed body 320, the connection point generally being located at the point where the first part 111 and the second part 112 connect.

[0098] The general position of the second adjustable airbag 340 corresponds to the human leg. When a user lies down, lounges, or sits back, the second adjustable airbag 340 can be inflated so that the support height of the leg can be increased to a certain extent, thus improving the comfort of users. While the second adjustable airbag 340 is illustrated in use with a multi-tier inflatable body, the second adjustable airbag 340 may also be used in conjunction with the singe-tier inflatable body illustrated in FIGS. 1-14.

[0099] The present disclosure provides an airbag structure for inflatable products, on which an adjustable support frame 10 is set. The adjustable support frame 10 can be used as a rigid, or hard, support to adjust the height of an inflatable bed or other inflatable products, and at the same time, the adjusted height can form a good, inclined plane, so as to improve the comfort of a user in use.

[00100] The present disclosure provides a support assembly 130 comprising an adjustable support frame 10, an adjustable airbag 20, and a fixing assembly 133, wherein the adjustable support frame 10 is arranged above the adjustable airbag 20 and is hinged with the fixing assembly 133. The present disclosure provides that the adjustable airbag 20 supports the inflatable body 210 by adjusting the support frame 10. As a hard support, the adjustable support frame 10 can adjust the height of the inflatable bed 210 or other inflatable products, and at the same time, the adjusted position can form a better inclined surface, thereby improving the comfort. The function of the adjustable airbag 22 is to control the opening angle of the adjustable support frame 10. The shape of the adjustable airbag 20 will not affect the supporting effect. Therefore, the present disclosure can realize the adjustment of the inflatable body without setting multiple adjustable airbags or specially shaped airbags.

Therefore, the present disclosure has the advantages of simple structure and good supporting effect. [00101] The present disclosure makes it possible to adjust the height of the inflatable body by setting a support assembly 130 between the upper bed body 310 and the lower bed body 320. When a user needs to sit, lounge, and/or lean, the first adjustable airbag 20 in the support assembly 130 can be filled with air, that is, the first part 111 of the upper bed body 310 can be adjusted to a certain tilt angle for the user to lean back, so as to achieve the user's sitting and leaning needs. When it is necessary to lie down, the air of the first adjustable airbag 20 can be released so that the adjustable support frame 10 will be folded on the lower bed body 320, the first part 111 of the upper bed body 310 will return to the lower bed body 320 as it loses support from the adjustable support frame 10 and adjustable airbag 20, and the bed surface of the upper bed body 310 will further present a generally flat state for users to lie down. It can be seen that the inflatable body of the present disclosure can be adjusted in height according to the needs of the user and can meet the needs of users such as lying and sitting. Moreover, the support assembly 130 has a simple structure. By adjusting the support frame to form a rigid support for the upper bed body 310, a better inclined surface can be formed at the adjusted position, thereby improving the comfort of a user sitting.

[00102] In addition, the present disclosure further sets a second adjustable airbag 340 between the upper bed body 310 and the lower bed body 320. When a user lie down or sit and lean, the second adjustable airbag 340 can be inflated, so that the support height of the legs can be increased to a certain extent, thereby improving the comfort of users.

[00103] It will be apparent to those skilled in the art that various modifications and variation can be made in the present disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the present disclosure cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
