[0054] Figure 1 A vehicle seat 10 is shown. The seat includes a frame 12 that supports a bottom cushion 14 and a back cushion 16. A set of massage bladders 18 is located between the frame and one or more of the cushions. An air distribution network 20 selectively distributes air from an air pump 22 to the massage bladders 18. A valve network 24 selectively directs air to a subset of the massage bladders 18. An occupant seated in the vehicle seat 10 can feel the inflation and deflation of the massage bladders 18 through the seat cushion.
[0055] Figure 2At least a portion of an example air distribution network 20 is shown. In some embodiments, air distribution network 20 can be used to distribute other fluids, such as water, oil, etc. A first set of sheets 26 provides a first plurality of rows 26RA, 26RB, 26RC, 26RD forming flow channels, each row having an inlet 26IA, 26IB, 26IC, 26ID and an outlet 26OA, 26OB, 26OC, 26OD, and being in fluid communication with a respective bladder 18A, 18B, 18C, 18D. In some embodiments, sheets 26 can be a polymeric material, such as a thermoplastic polyurethane (TPU). Sheets 26 described herein can be joined together by a set of welds 28 to form flow channel rows 26RA, 26RB, 26RC, 26RD and flow channel columns 26C. Welds 28 can be formed using any technique for forming a gas-tight joint, such as high frequency welding.
[0056] The first set of sheets 26 also provides a first column 26C transverse to the first plurality of rows 26RA, 26RB, 26RC, 26RD. As will be further explained, when first column 26C is filled with fluid, first column 26C prevents fluid from flowing from respective inlets 26IA, 26IB, 26IC, 26ID of the first plurality of rows 26RA, 26RB, 26RC, 26RD to respective outlets 26OA, 26OB, 26OC, 26OD. The cavity provided by column 26C is fluidically separated from the fluid pathways provided by rows 26RA, 26RB, 26RC, 26RD.
[0057] As shown schematically, fluid lines 27 can fluidically connect outlets 26OA, 26OB, 26OC, 26OD to their respective bladders 18A, 18B, 18C, 18D. The first set of sheets 26 is fluidically arranged between pump 22 (see Figure 1 ) and bladders 18A, 18B, 18C, 18D.
[0058] As shown in Figure 3 and Figure 4 , in some embodiments, the first set of sheets 26 includes four layered thermoplastic polyurethane sheets 26S1, 26S2, 26S3, 26S4. With reference to Figure 3 (removing sheets 26S1, 26S4 for ease of viewing), the first plurality of rows 26RA, 26RB, 26RC, 26RD can be provided by a second sheet 26S2 and a third sheet 26S3, with welds 28 providing boundaries of rows 26RA, 26RB, 26RC, 26RD, and rows 26RA, 26RB, 26RC, 26RD providing sealed and fluidically separated fluid paths.
[0059] With reference to Figure 4(Sheets 26S1 and 26S4 are shown), the first sheet 26S1 and the fourth sheet 26S4 can provide column 26C (see...). Figure 2 ), and located between inlets 26IA, 26IB, 26IC, 26ID and outlets 26OA, 26OB, 26OC, 26OD. In some embodiments, column 26C may be substantially perpendicular to rows 26RA, 26RB, 26RC, 26RD. As will be further explained, air filling the cavity provided by column 26C compresses the second sheet 26S2 and the third sheet 26S3 together to block the fluid path through rows 26RA, 26RB, 26RC, 26RD, thereby preventing fluid from flowing to outlets 26OA, 26OB, 26OC, 26OD. Sheet 26S1 may be welded to sheet 26S2, and sheet 26S4 may be welded to sheet 26S3. In some embodiments, sheets 26S1 and 26S4 may not span the width of sheets 26S2 and 26S3.
[0060] like Figure 5 As shown, a second set of sheets 30, constructed similarly to sheet 26, can similarly provide a second multi-row 30RE, 30RF, 30RG, 30RH in fluid communication with the corresponding bladders 18E, 18F, 18G, 18H, and a second column 30C transverse to the second multi-row 30RE, 30RF, 30RG, 30RH. When the second column 30C is filled with fluid, it prevents fluid from flowing from the corresponding inlets 30IE, 30IF, 30IG, 30IH of the second multi-row 30RE, 30RF, 30RG, 30RH to the corresponding outlets 30OE, 30OF, 30OG, 30OH. In the exemplary distribution network 20, the grouped sheets 26, 30 can be arranged in an overlapping stacked manner. As will be further discussed below, a common inlet valve regulates the fluid flow into one row of the first multi-row and one row of the second multi-row.
[0061] like Figure 6 As shown, the second set of sheets 32, constructed similarly to sheets 26 and 30, can similarly provide a third multi-row 32RI, 32RJ, 32RK, 32RL in fluid communication with the corresponding bladders 18I, 18J, 18K, 18L, and a third column 32C transverse to the third multi-row 32RI, 32RJ, 32RK, 32RL. When the third column 32C is filled with fluid, the third column 32C prevents fluid from flowing from the corresponding inlets 32II, 32IJ, 32IK, 32IL of the third multi-row 32RI, 32RJ, 32RK, 32RL to the corresponding outlets 32OI, 32OJ, 32OK, 32OL.
[0062] In the exemplary distribution network 20, the grouped sheets 26, 30, 32 can be arranged in an overlapping stacked manner (see [link]). Figure 7As will be discussed below, one or more of 32RI, 32RJ, 32RK, 32RL can share an inlet valve with one or more rows from the set of sheets 26, 30. In some embodiments, each row of the first plurality 26RA, 26RB, 26RC, 26RD can share a valve with a separate row of the second plurality 30RE, 30RF, 30RG, 30RH and a separate row of the third plurality 32RI, 32RJ, 32RK, 32RL. However, as will be discussed below, columns 26C, 30C, and 32C allow the dispensing network 20 to selectively and individually fill the capsules 18A-18L with fewer valves than the number of capsules being used.
[0063] In some embodiments, more or fewer than three sets of sheets 26, 30, 32 can be used. In some embodiments, more or fewer than four rows can be used for each set of sheets. Although each of the first, second, and third sets of sheets has an equal number of rows in the illustrative example, in some embodiments, some of the sets of sheets can have an unequal number of rows.
[0064] As shown in FIG. 1, the dispensing network 20 includes a first set of sheets 26, a second set of sheets 30, and a third set of sheets 32. The first set of sheets 26 includes a first plurality of rows 26RA, 26RB, 26RC, 26RD. The second set of sheets 30 includes a second plurality of rows 30RE, 30RF, 30RG, 30RH. The third set of sheets 32 includes a third plurality of rows 32RI, 32RJ, 32RK, 32RL. Figure 7 and Figure 8 As shown in FIG. 1, the dispensing network 20 includes a first set of sheets 26, a second set of sheets 30, and a third set of sheets 32. The first set of sheets 26 includes a first plurality of rows 26RA, 26RB, 26RC, 26RD. The second set of sheets 30 includes a second plurality of rows 30RE, 30RF, 30RG, 30RH. The third set of sheets 32 includes a third plurality of rows 32RI, 32RJ, 32RK, 32RL. Figure 7 As shown in FIG. 1, the dispensing network 20 includes a first set of sheets 26, a second set of sheets 30, and a third set of sheets 32. The first set of sheets 26 includes a first plurality of rows 26RA, 26RB, 26RC, 26RD. The second set of sheets 30 includes a second plurality of rows 30RE, 30RF, 30RG, 30RH. The third set of sheets 32 includes a third plurality of rows 32RI, 32RJ, 32RK, 32RL.
[0065] Figure 8 The fluid flow paths within the example dispensing network 20 are shown schematically. Valve VI regulates flow into rows 26RA, 30RE, and 32RI. Valve V2 regulates flow into rows 26RB, 30RF, and 32RJ. Valve V3 regulates flow into rows 26RC, 30RG, 32RK. Valve V4 regulates flow into rows 26RD, 30RF, and 32RL. Columns 26C, 30C, and 32C allow the dispensing network 20 to selectively and individually fill the capsules 18A-18L with fewer valves than the number of capsules being used.
[0066] Each of the capsules 18A-18L can be filled individually without filling the others of the capsules 18A-18L. For example, to selectively fill the capsule 18A, the valve VI is opened, and the valves V2, V3, V4 are closed. Closing the valves V2, V3, V4 prevents flow to the capsules 18B-18D, 18F-18H, and 18J-18L. The valves V6 and V7 are opened to pinch and prevent flow through the lines 30RE and 32RI, thereby preventing flow to the capsules 18E and 18I. The valve V5 is closed to allow flow through the line 26RA to the capsule 18A.
[0067] As another example, to selectively fill the capsule 18B, the valve V2 is opened, and the valves VI, V3, and V4 are closed. The valves V6 and V7 are opened to pinch and prevent flow through the lines 30RF and 32RJ. The valve V5 is closed to allow flow through the line 26RB to the capsule 18B.
[0068] As another example, to selectively fill the capsule 18G, the valve V3 is opened, and the valves VI, V2, and V4 are closed. The valves V5 and V7 are opened to pinch and prevent flow through the lines 26RC and 32RK. The valve V6 is closed to allow flow through the line 30RG to the capsule 18G.
[0069] As another example, to selectively fill the capsule 18L, the valve V4 is opened and the valves VI, V2, V3 are closed. The valves V5 and V6 are opened to pinch and prevent flow through the lines 26RD and 30RH. The valve V7 is closed to allow flow through the line 32RL to the capsule 18L.
[0070] The remaining capsules can be filled individually in a similar manner. In other words, to fill a capsule, the associated one of the valves VI, V2, V3, V4 is opened, and the remaining ones of the valves VI, V2, V3, V4 are closed. The associated column valves V5, V6, V7 are closed, and the other ones of the column valves V5, V6, V7 are opened.
[0071] In embodiments, the plurality of capsules 18A-18L comprise discrete inflatable / deflatable bags or units for massage and / or lumbar / cushion seat features associated with the seat cushions 14, 16. In some embodiments, venting of the capsules 18A-18L can be reversed through the same fluid paths described above.
[0072] In some embodiments, as shown, N inlet valves and M column valves can be used to individually control flow to NxM capsules. For example, four inlet valves VI, V2, V3, V4 and three column valves V5, V6, V7 are used to individually control flow to 12 capsules 18A-18L. Thus, less than one valve is used for each capsule. Other numbers of valves and / or capsules can be used in accordance with the present disclosure.
[0073] As illustratively shown, one or more controllers 34 can control the disclosed valves to supply fluid flow from the pump 22 (see Figure 1 ) to selected control fluid lines.
[0074] In embodiments, the one or more controllers 34 can include a processor, memory, and one or more input and / or output (I / O) device interfaces communicatively coupled via a local interface. The local interface can include, for example and without limitation, one or more buses and / or other wired or wireless connections. The one or more controllers 34 can be a hardware device for executing software, particularly that stored in memory. The one or more controllers C can be a custom-made or off-the-shelf processor, a central processing unit (CPU), an auxiliary processor associated with the computing device, a semiconductor-based microprocessor (in the form of a microchip or chip set), or generally any device for executing software instructions. The memory can include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, VRAM, etc.)) and / or nonvolatile memory elements (e.g., ROM, hard drive, tape, CD-ROM, etc.). The software in the memory can include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. The one or more controllers 34 can be configured to execute the software stored within the memory to communicate data to and from the memory, and generally, to control operations of the computing device pursuant to the software.
[0075] As shown in Figure 9 , any of the disclosed sets of sheets can include an opening 36 at a row R to provide fluid communication between associated rows R in separate sets of sheets sharing an inlet valve. The opening 36 is upstream of the columns C. In some embodiments, one or more intermediate sets of sheets can have an opening 36 in both sheets forming the row R, while outer sets of sheets can have an opening 36 only on the inner sheet forming the row R. The respective openings 36 can be aligned across the sets of sheets and sealingly connected. In some embodiments, the opening 36 can provide any inlet to the disclosed rows R. Additionally or alternatively, a set of rows R can have a separate opening providing an inlet to which a shared valve is coupled.
[0076] The method according to any of the disclosed embodiments can include inflating one of a plurality of bladders disposed within a seat. The inflating can include selecting a row of a first set of sheets having an outlet thereof in fluid communication with the one of the plurality of bladders; opening a valve associated with a first inlet of the selected row; pumping fluid across the open valve into the selected row; and inflating a column of a second set of sheets having a second set of one or more outlets associated therewith of other bladders of the plurality of bladders to prevent fluid flow from a second row of the second set of sheets in fluid communication with the first inlet to the second set of one or more outlets.
[0077] In some aspects, a system can include a first set of sheets providing a first plurality of rows each having an inlet and an outlet, and a first column transverse to the first plurality of rows that prevents fluid flow from a respective inlet to a respective outlet of the first plurality of rows when it is filled with fluid; a second set of sheets providing a second plurality of rows and a second column transverse to the second plurality of rows that prevents fluid flow from a respective inlet to a respective outlet of the second plurality of rows when it is filled with fluid; and a common inlet valve disposed at an inlet of a row of the first plurality of rows, the common inlet valve regulating fluid flow into the row of the first plurality of rows and a row of the second plurality of rows.
[0078] In some aspects, a system can include a third set of sheets providing a third plurality of rows and a third column transverse to the third plurality of rows that prevents fluid flow from a respective inlet to a respective outlet of the third plurality of rows when it is filled with fluid, a common inlet valve regulating fluid flow into a row of the third plurality of rows.
[0079] In some aspects, the first set of sheets and the second set of sheets comprise thermoplastic polyurethane sheets.
