DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The detailed description and technical content of the present invention will now be described in combination with drawings as follows.

[0025] Referring to FIGS. 1 to 4, the present invention provides an air bag module of inflatable mattress, the inflatable mattress including a lining 2 and a resilience supplying module 3 (for example, a sponge mat). Moreover, the air bag module and the resilience supplying module 3 may be placed in the lining 2 so as to form the inflatable mattress. Specifically, the air bag module includes at least one air bag unit 1, the air bag unit 1 being provided with an air distribution layer 11 and a hardness adjustment layer 12. The hardness adjustment layer 12 and the air distribution layer 11 are connected and stacked, as illustrated in FIG. 4. In this case, the air distribution layer 11 is provided with at least two distributing air bags 111 side-by-side disposed while communicated with one another, and a plurality of first air-guiding portions 112 disposed, along the connection between the two distributing air bags 111, at an interval between each other. In one embodiment, the air distribution layer 11 is provided with an air delivery tube 113, as illustrated in FIGS. 3 and 4. The air delivery tube 113 is provided at one end of each distributing air bag 111, so as to be communicated with the distributing air bags 111. In addition, the hardness adjustment layer 12 is provided with a plurality of supporting air bags 121 connected but not communicated with one another, and a plurality of second air-guiding portions 122, each second air-guiding portion 122 being provided in one of the supporting air bags 121, respectively. In one embodiment, each second air-guiding portion 122 is located at the center of the surface of one of the supporting air bags 121, respectively. Furthermore, the supporting air bags 121 are provided on the surfaces of the two distributing air bags 111, while each second air-guiding portion 122 is communicated with one of the first air-guiding portions 112, respectively. In one embodiment, each first air-guiding portion 112 is a first air-guiding hole, while each second air-guiding portion 122 is a second air-guiding hole communicated with one of the first air-guiding holes, respectively. In addition, each distributing air bag 111 may be presented in the form of a long strip and arranged to form a rectangular pattern, respectively. Each of the supporting air bags 121 may be presented in the shape of a rectangle, respectively, while these supporting air bags 121 are connected together to form a rectangular pattern of the shape the same as that formed by the distributing air bags 111 after being arranged, as illustrated in FIG. 4.

[0026] In the above paragraph, the fundamental embodied structure of the air bag module has been expounded clearly. Subsequently, the operation process and the embodied pattern created in the course of operation of the air bag module will be described for the present invention. In this connection, referring to FIGS. 1 to 4 again, the air bag module and the resilience supplying module 3 are put into the lining 2 in turn during the operation process of the air bag module, such that the air bag module is allowed to bear the resilience supplying module 3 at the bottom thereof; that is to say, the hardness adjustment layer 12 is located between the air distribution layer 11 and the resilience supplying module 3. Further, the number of each of the air bag module, the air bag unit 1, the lining 2 and the resilience supplying module 3 may be more than one in the implementation (as illustrated in FIGS. 1 and 2), while the combined air bag modules, the linings 2 and the resilience supplying module 3 are placed between a base plate 4 and a mattress body 5, such that an air bed is formed of the air bag modules, the linings 2, the resilience supplying module 3, the base plate 4 and the mattress body 5 integrally, as illustrated in FIG. 1. In one embodiment, the air bag module is provided with a plurality of the air bag units 1, and the resilience supplying module 3 is provided with a plurality of the elastic bodies 31 (such as, elastic sponges, for example), as well as the lining 2 is provided with a plurality of lattice-like units 21 arranged in parallel with one another, each lattice-like unit 21 defining a mounting space 210 therein, each mounting space 210 being provided for at least one of the air bag units 1 and at least one of the elastic bodies 31 to be placed therein, respectively.

[0027] Here, for facilitating the explanation of detailed variation of the air bag module in the practical use, the relationship among only one single air bag unit 1 and other components will be described in the following paragraphs. In detail, primary hardness is provided by the resilience supplying module 3 for the hardness of the inflatable mattress when the air bag unit 1 is uninflated. At this time, the lowest hardness of the inflatable mattress is perceived by a user lying on the mattress body 5. If increasing the hardness of the mattress is desired, an inflating device (not shown in the figures) may be connected to the air delivery tube 113 by the user, so as to inject air into the supporting air bag 121 through the inflating device. In one embodiment, the inflatable mattress is further provided with a filler strip 6 (such as, a sponge strip, for example) located above the air delivery tube 113. When the air bag unit 1 is being inflated, air is injected into each supporting air bag 121 from the two distributing air bags 111 through the first air-guiding portions 112 and the second air-guiding portions 122 (as illustrated in FIGS. 5 and 6). In this way, expanded volume and increased hardness may be then generated for each supporting air bag 121 owing to injected air. Thereby, the hardness of the inflatable mattress may be adjusted by users via the inflating device depending upon their own requirements. In this case, it should be noted that distribution of air and adjustment of hardness are performed by the air distribution layer 11 and the hardness adjustment layer 12 separately in the air bag unit 1 of the present invention. In the air distribution layer 11, air is inputted into each of the distributing air bags 111 equally via intercommunication with one another of the distributing air bags 111, in such a way that air coming from the distributing air bags 111 is consistently received by each supporting air bag 121 of hardness adjustment layer 12 independent of one another. Thus, in the process of adjustment of hardness, the inflatable mattress may be inflated consistently and evenly. Thereby, the problem of uneven surface of bed due to non-uniform inflation in the conventional structure is solved.

[0028] Then, for the purpose of inflating the air bag unit 1 more evenly, the air distribution layer 11 is further provided with a plurality of first connection lines 114 (for example, welding lines, i.e., fusion regions formed due to welding) in one embodiment as illustrated in FIGS. 4 and 5. The first connection lines 114 are provided, at an interval between each other, on the connection between the two distributing air bags 111, so as to isolate the two distributing air bags 111 from each other. Each first air-guiding portion 112 is provided between any two adjacent first connection lines 114, respectively. Accordingly, the first connection lines 114 are allowed for separating the two distributing air bags 111 from each other substantially in the air distribution layer 11, such that air is inputted into each of the two distributing air bags 111 equally. Furthermore, the hardness adjustment layer 12 is further provided with a plurality of second connection lines 123 (for example, welding lines, i.e., fusion regions formed due to welding), as illustrated in FIGS. 4 and 6. The second connection lines 123 are provided on the connection between any two adjacent supporting air bags 121, respectively, so as to isolate these two adjacent supporting air bags 121. Thus, expansion deformation generated on the edge of each supporting air bag 121 when air is injected may be avoided via one of the second connection lines 123, respectively.
