Description

SUSPENSION PLATE ASSEMBLY FOR PNEUMATICSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to U.S. Provisional Application No. 63 / 561,881, filed March 6, 2024 and incorporated herein by reference in its entirety.FIELD

[0002] The present teachings generally relate to a suspension plate assembly for pneumatic components.BACKGROUND

[0003] Some vehicles include enhanced passenger comfort features in their seats for heating, cooling, massaging, posture adjustment, and the like. These seats can provide comfort, therapy, and alertness to passengers.

[0004] Some seats employ air bladders for massaging and posture adjustment. The air bladders are selectively inflated to extend and deflated to retract, thus acting upon the occupant through the surface of the cover or trim layer of the seat. In this regard, pneumatic pumps operate to provide air to the air bladders.

[0005] Secondary pneumatic pumps may provide a pulsation function, such as described in U.S. Patent No. 11,759,382 B2, incorporated herein by reference in its entirety for all purposes. Such pulsation may act independently of or in cooperation with the functioning of a primary pneumatic pump.

[0006] Pneumatic pumps can be mounted to a frame in the seat back portion and seat cushion portion of the seat, such as described respectively in U.S. Patent Nos. 8,162,398 B2 and 10,661,692 B2, incorporated herein by reference in their entireties for all purposes. Although, these disclosures do not address packaging both primary and secondary pneumatic pumps, where the secondary pneumatic pumps function to provide pulsation.

[0007] Typically, seats have greater packaging space located in or under the seat bottom, such as below the seat frame and above the floor of the vehicle. However, packaging of pneumatic pumps in or under the seat bottom requires additional lengths of air lines for supplying air bladders in the seat back portion of the seat. Also, the region where the seat bottom meets the seat back portion of the seat typically includes various reinforcements and hardware for seat reclining features that limit the routing of air lines and risks pinch points of the air lines.

[0008] There is a persistent need to manage packaging space in vehicles, particularly in vehicle seats where enhanced passenger comfort features are included. Current trends in the industry are to generally reduce the size and weight of vehicles, thus addressing fuel or battery milage. However, size and weight reductions must be considered against the backdrop of passenger comfort and improved functioning of passenger comfort features.

[0009] It would be desirable to provide a pulsation module and suspension plate assembly that is suitable for reduced packaging spaces relative to conventional hardware and their arrangements in seats.

[0010] It would be desirable to provide a pulsation module and suspension plate assembly that provides leg room for rearward passengers.

[0011] It would be desirable to provide a pulsation module and suspension plate assembly with reduced mass and cost relative to conventional hardware.

[0012] It would be desirable to provide a pulsation module and suspension plate assembly having relatively fewer pieces and that is relatively simpler to assemble.

[0013] It would be desirable to provide a pulsation module and suspension plate assembly that offers greater response time for delivering air to air bladders, relative to conventional systems, and a broader range of adjustment for calibrating the system.SUMMARY

[0070] The present teachings meet one or more of the above needs by the improved suspension plate assembly described herein. The suspension plate assembly may be a part of a massage and / or posture adjustment system. The massage and / or posture adjustment system may be located in a seat. The seat may be located in a vehicle (e.g., an automobile, train, airplane, or the like) or may be furniture (e.g., an office chair).

[0071] The suspension plate assembly may function to receive a compressor, receive a pulsation module, receive one or more valve assemblies, receive one or more manifolds, receive one or more controllers, position one or more air lines, mount within a seat back portion or a seat base portion of a seat, or any combination thereof. The suspension plate assembly may receive and secure the various hardware described herein. The hardware described herein may be secured in pre-determined locations and provide staging for ease of assembly.

[0072] The suspension plate assembly may be located within a cavity in a seat. The suspension plate assembly may be located behind or underneath a foam layer in the seat. The foam layer of the seat may be located behind underneath a cover or trim layer of the seat.

[0073] The suspension plate assembly may fasten to a frame of a seat, be suspended from a frame of a seat, or both. Fastening may be by one or more screws, bolts, rivets, ties, cables, wires, snaps, adhesives, or any combination thereof. Suspension may be by one or more wires or cables connected to the suspension plate assembly at one end and connected to a frame of a seat on the other end. In this regard, the wires or cables may provide for at least some movement of the suspension plate assembly relative to a frame and vibrational damping. By way of example, a wire or cable may be engaged at one end to the suspension plate assembly and at another end to the frame. The ends of the wire may include hooks or loops.

[0074] The suspension plate assembly may comprise a suspension plate. The suspension plate may function as a support for the foam layer and as mounting surface for one or more air bladders, housings (e.g., a compressor or pulsation module housing), compressors, pulsation modules, air lines, air line connectors, manifolds, valve assemblies, electronic devices (e.g., controllers), any other hardware described herein, or any combination thereof. The suspension plate may be fastened to or suspended from a frame of a seat.

[0075] The suspension plate may be generally planar, include a curvature, or both. The curvature may be commensurate with the typical anatomical curvature of a spine. For example, the suspension plate may curve outward toward an occupant in the lumbar area. The curvature may be commensurate witha curvature of the seat in which it is located. The suspension plate may have a generally rectangular profile.

[0076] The suspension plate may have a first side and a second side. The second side may oppose the first side. The first side (A-side) may be oriented toward a front of the seat. The second side (B-side) may be oriented toward a rear of the seat. The first side may be oriented toward an occupant seated upon the seat. The first side may be adjacent to a foam layer. The second side may be oriented away from an occupant seated upon the seat. The second side may be oriented toward an occupant seated behind the seat, such as in a passenger row. Unless otherwise stated herein, first side (A-side) and second side (B-side) may similarly apply to the orientations of other elements or layers in the seat (e.g., the foam layer).

[0077] The massage and / or posture adjustment system may comprise one or more air bladders. The one or more air bladders may function to provide massage and / or posture adjustment to an occupant. The one or more air bladders may selectively inflate to extend toward an occupant and deflate to retract from an occupant. Stated differently, the one or more air bladders may selectively inflate to apply a pressure upon an occupant and deflate to release pressure from an occupant. The one or more air bladders may act upon an occupant through the cover or trim layer of a seat. The one or more air bladders may be located on a first or second side of the foam layer.

[0078] Typically, a plurality of air bladders may be located in a seat base portion and / or a seat back portion. The air bladders may be generally arranged in one or more rows. A row may extend along a central axis of the suspension plate. One or more rows may extend offset (e.g., leftward and / or rightward) from a central axis of the suspension plate. Thus, multiple areas of an occupant’s body may be acted upon by the air bladders. The air bladders may be arranged with at least one axis of symmetry, possibly even two axes of symmetry.

[0079] The air bladders may include a first set of air bladders and a second set of air bladders. The first and second sets of air bladders may provide different functions. The first set of air bladders may function to provide support or kneading. The second set of air bladders may function to provide pulsing. Although, the present teachings contemplate support, kneading, and pulsing provided by the same air bladders. At least a portion of the first set may be co-located with at least a portion of the second set. That is, located in a stacked or layered arrangement.

[0080] The suspension plate assembly may comprise one or more compressors. The one or more compressors may function to act upon the one or more air bladders, such as inflating the one or more air bladders. Exemplary compressors may include positive displacement compressors, such as diaphragm compressors, reciprocating compressors, or the like that are operable to pressurize air.

[0081] The one or more compressors may include a first compressor and a second compressor. The first compressor may be a pulsation module. The pulsation module may function to provide pulsation to the one or more air bladders. In this regard, pulsation may occur at a high frequency. The pulsation module may provide the sensation of vibration in cooperation with the second compressor. That is, thesecond compressor may pressurize the massage and / or posture adjustment system, including the air lines and the selected air bladders, and the pulsation module may act upon the already pressurized system. Such operation will be further described herein, such as with reference to FIG. 5 and FIG. 6. The first compressor may operate at a higher frequency relative to the second compressor.

[0082] High frequency may mean about > 1 Hz, more preferably about 3-100 Hz, or even more preferably about 60-80 Hz. Low frequency may mean about < 1 Hz, more preferably 0.02-0.2 Hz, or even more preferably 0.03-0.1 Hz. Frequency in this context may mean a cycle defined by an inflation event and a deflation event.

[0083] The pulsation module may comprise one or more pneumatic elements and an actuating element. The one or more pneumatic elements may be connected to the one or more air bladders by one or more air lines. Each pneumatic element may be connected to one air bladder by an air line. Each pneumatic element may be connected to two or more air bladders by respective air lines. One or more valve assemblies or manifolds may be located upstream of the pulsation module and downstream of the one or more air bladders.

[0084] The actuating element may actuate the one or more pneumatic elements. The one or more pneumatic elements may be actuated independently of one another. The actuating element may change an interior volume of the one or more pneumatic elements by a mechanical motion. Reduction of the interior volume forces air through an air line and into an air bladder. Thus, the air bladder may inflate by a volume commensurate with the reduction of the interior volume of the pneumatic element.

[0085] The one or more pneumatic elements may be arranged concentrically within an interior volume of a cylinder. The actuating element may comprise a roller disposed within the interior volume of the cylinder. The roller may be arranged eccentrically relative to the cylinder. Eccentric motion of the roller about a central axis of the cylinder may cause changes in the interior volume of the one or more pneumatic elements.

[0086] The roller may be connected to a drive element such as a motor (e.g., a servomotor). One or more connections may be disposed between the roller and the drive element. The one or more connections may include shafts, gears, belts, chains, the like, or any combination thereof. The rotational frequency of the motor may be controlled.

[0087] Exemplary pulsation modules are described in U.S. Patent No. 11,759,382 B2, incorporated herein by reference in its entirety for all purposes.

[0088] The one or more compressors may comprise one or more outlets. The one or more outlets may extend from one of two opposing ends of the cylinder. The opposing ends may be arranged in opposition along the largest dimension (e.g., length) of the cylinder. The one or more outlets may pneumatically communicate with the pneumatic elements.

[0089] The suspension plate may comprise one or more apertures extending from the first side to the second side of the suspension plate. The one or more apertures may accommodate one or more air lines extending from the one or more pumps to the one or more air bladders. In another aspect, at least someair lines may wrap around edges of the suspension plate. A combination of these approaches is also contemplated.

[0090] The suspension plate assembly may comprise one or more compressor housings. The one or more compressor housings may function to receive a compressor (e.g., a pulsation module). The one or more compressor housings may be located on a second side of the suspension plate.

[0091] The one or more compressor housings may comprise one or more segments. The one or more compressor housings may comprise at least a first segment and a second segment. Although the present teachings are not intended to be limiting of the number of individual segments of the compressor housing. The first and second segments may define a space. A compressor may be located within the space. The second segment may be at least partially separable from the first segment to locate the compressor within the space.

[0092] The one or more segments may connect together by one or more hinges, fasteners, or both. For example, first and second segments may be connected by a living hinge. That is, a strip of material integrally connecting the first and second segments and deformable by plastic or elastic deformation. As another example, first and second segments may be connected by a mechanical hinge (e.g., a barrelstyle hinge). As another example, first and second segments may be connected by one or more fasteners. The one or more fasteners may include one or more screws, bolts, rivets, clips, snaps, adhesives, or any combination thereof.

[0093] The first segment may be connected to the second side of the suspension plate. The first segment may be fastened to the second side of the suspension plate. Said fastening may be by one or more screws, bolts, rivets, clips, snaps, adhesives, or any combination thereof. The first segment may be integrally formed to the second side of the suspension plate. Said integral formation may be by molding, casting, or material addition (e.g., 3D printing). Preferably, the first segment may be integrally formed to the suspension plate. In this regard, there may be a reduction in mass by eliminating fasteners, the quantity of individual pieces forming the suspension plate assembly may be reduced, and assembly of the suspension plate assembly with the seat may be simplified.

[0094] In another aspect, the pulsation module may be located off-board the suspension plate. The pulsation module may be located within a cross-member of a frame of a seat. The cross-member may be a bottom cross-member, which is located proximate to a bottom edge of the seat back and proximate to a back edge of a seat base. The cross-member may have a cavity or pocket in which the pulsation module may locate.

[0095] In another aspect, the second compressor may be secured to an arm extending from an edge of the suspension plate.

[0096] The suspension plate may be located in a seat back portion and / or a seat base portion. The suspension plate may have a first end adapted to orient toward a top of a seat back portion and a second end oriented toward a bottom of a seat back portion. The second end may oppose the first end. Where the seat includes a headrest, the first end may be adapted to orient toward the headrest. The first endmay be adapted to orient toward a front of a seat base portion. The second end may be adapted to orient toward a back of a seat base portion. The second end may oppose the first end.

[0097] The largest dimension (e.g., length) of the compressor (e.g., the pulsation module) may be oriented extending between the first and second ends of the suspension plate. The largest dimension (e.g., length) of the compressor (e.g., the pulsation module) may be oriented extending between left and right ends of the suspension plate.

[0098] The compressor (e.g., the pulsation module) may be aligned along a central axis of the suspension plate. In this regard, the length of air lines extending from the compressor may be less relative to a placement of the compressor offset from the central axis, where air bladders are aligned along or proximate to a central axis of the suspension plate. Alignment of the pump housing with the central axis may provide for generally equal air line length extending from the pulsation module to adjacent air bladders (e.g., adjacent air bladders disposed leftward and rightward of a central axis of the suspension plate), which may improve simultaneous inflation of adjacent air bladders.

[0099] The present teachings contemplate that shortening the air lines may improve the responsiveness of air delivery to the one or more air bladders. Lesser length of the air lines results in a lower overall system volume, increasing the responsiveness. Moreover, volume may limit the range of adjustment of the pulsation module. That is, with a relatively greater system volume, the adjustment range can be narrow, while with a relatively lesser system volume, the adjustment range can be broad. In other words, the adjustment range may be proportional to the system volume.

[0100] The pump housing may be offset from a central axis of the suspension plate (e.g., leftward or rightward). In this regard, space may be provided for additional hardware mounted to the suspension plate. Such additional hardware may include one or more other pumps, air lines, air line connectors, manifolds, valve assemblies, electronic devices (e.g., controllers), or any combination thereof.

[0101] One end of the compressor (e.g., the pulsation module) may be located closer to the first end of the suspension plate or closer to the second end of the suspension plate, or both of the ends of the compressor may be located generally equidistant respectively to the first and second ends of the suspension plate. The construction of the seat may determine the location of the pump housing. For example, some regions of a seat may provide greater clearance for the compressor and air lines connected to the compressor.

[0102] The compressor and / or housing may comprise a wiring harness. The wiring harness may provide for electrical connection with the compressor. The electrical connection may be with the electrical system of the vehicle. Power and / or signal communication may be provided to the compressor via the wiring harness.

[0103] The suspension plate assembly may comprise one or more air line connectors. The one or more air line connectors may function to receive air lines, provide a transition between different lengths of air lines (e.g., lengths extending between the first and second sides of the suspension plate), aid in assembly, or any combination thereof. In this regard, at least some air lines may be located in the seatduring a first assembly step, and any air lines introduced during a second assembly step may be aided in connection to the preceding air lines via the air line connectors.

[0104] Air line connectors (“connectors”) may refer to single connectors or assemblies of multiple connectors (“connector assembly”).

[0105] The one or more air line connectors may be fastened to the suspension plate. Said fastening may be by one or more screws, bolts, rivets, clips, snaps, adhesives, or any combination thereof. The one or more air line connectors may be integrally formed to the suspension plate. Said integral formation may be by molding, casting, or material addition (e.g., 3D printing). Preferably, at least a portion of the one or more air line connectors may be integrally formed to the suspension plate. In this regard, there may be a reduction in mass by eliminating fasteners, the quantity of individual pieces forming the suspension plate assembly may be reduced, and assembly of the suspension plate assembly with the seat may be simplified.

[0106] The air line connectors may include one inlet for every one outlet, one inlet for multiple outlets, multiple inlets for one outlet, or any combination thereof. The air line connectors may include splitters by which one air line is split into two or more separate air lines.

[0107] The one or more air line connectors may receive air lines. Engagement of the air lines may be via barbed fittings, push-to-connect fittings, threaded fittings, compression fittings, the like, or any combination thereof. Engagement of the air line connectors with the air lines may further include one or more clamps, such as hose clamps.

[0108] A first air line may extend from the pulsation module to one of the air line connectors. A second air line may extend from one of the air line connectors to one of the air bladders. One or more manifolds and / or valve assemblies may be located between the air line connector and air bladders. Although, in some aspects, one or more air lines may be connected at one end to a compressor (e.g., the pulsation module) and at the other end to an air bladder. The air line connectors may provide for fluid communication between the first and second air lines. This arrangement may be employed for some or all of the air lines. In this regard, routing of air lines may be simplified.

[0109] The suspension plate assembly may comprise one or more valve assemblies. The one or more valve assemblies may function to selectively open and / or close pneumatic communication between a compressor and the one or more air bladders. The valve assemblies may comprise a plurality of valves, a plurality of connectors, or both. Exemplary valves may include solenoid valves. Exemplary connectors may include barbed fittings, push-to-connect fittings, threaded fittings, compression fittings, the like, or any combination thereof.

[0110] In some aspects a valve assembly may comprise a controller. The controller may provide signals for actuating the valves. Although, the present teachings contemplate that the controller may be located off-board from the valve assembly.[oni] The suspension plate assembly may comprise acoustic and / or vibrational dampening. The acoustic and / or vibrational dampening may function to mitigate sound and / or vibrations generated bythe compressor. In some aspects, the dampening may include elastic members or insulation provided at the interface of the compressor and / or housing with the suspension plate, at the interface of the suspension plate with a frame of the seat, or both. In some aspects, the dampening may comprise elastic members or insulation within the housing, disposed between the compressor (e.g., the pulsation module) and the housing.

[0112] The suspension plate assembly may be free of any acoustic and / or vibrational dampening. In this regard, vibrations may be adapted and configured to contribute to a massage effect upon the passenger. Such vibrational translation from the compressor (e.g., the pulsation module) to the passenger may be enhanced by rigid fastening of the compressor and / or housing to the suspension plate, integral forming of the compressor and / or housing to the suspension plate, rigid fastening of the suspension plate to a frame of the seat, or any combination thereof.

[0113] FIG. 1 illustrates a seat 10 comprising an exemplary suspension plate assembly 12 according to the present disclosure. The seat 10 comprises a frame 14, which functions to define the structure of the seat 10 and to which the suspension plate assembly 12 is connected. In this regard, the suspension plate assembly 12 includes a suspension plate 16 within which a wire 18 is overmolded, and where the wire 18 connects to the frame 14 of the seat 10. The wire 18 also provides a connection point for cables to tie suspension plate assembly 12 to the frame 14.

[0114] The suspension plate assembly 12 further comprises a pulsation module 20 as described herein. The pulsation module 20 is arranged vertically and generally centrally on the suspension plate 16, providing for a desired packaging space of the pulsation module 20 and other components described below. The suspension plate 16 comprises a compressor 22, which functions to provide air to the pulsation module 20. For example, the compressor 22 may provide pressurized air to the pneumatic elements (see, e.g., FIG. 5) in the pulsation module 20.

[0115] The suspension plate assembly 12 further comprises a first valve assembly 24 and a second valve assembly 26. The first valve assembly 26 functions to selectively open and close pneumatic flow between the pulsation module 20 and air bladders (not shown) located on the opposing side of the suspension plate 16. The second valve assembly 26 functions to selectively open and close pneumatic flow between the compressor 22 and the air bladders (not shown) located on the opposing side of the suspension plate 16.

[0116] The suspension plate assembly 12 further comprises two connector assemblies 28, 30, which function to facilitate installation of the sub-components upon the suspension plate 16. For example, the first and second valve assemblies 24, 26, including associated air lines 32 thereof, can be assembled in a first assembly step, and the pulsation module 20, including associated air lines 32 thereof, can be assembled in a second assembly step.

[0117] A first length 34 of air line 32 connects the pulsation module 20 with the compressor 22. A second length 36 of air lines 32 connect the pulsation module 20 with the connector assemblies 28, 30. A third length 38 of air lines 32 connect the connector assemblies 28, 30 with the first valve assembly24. A fourth length 40 of air lines 32 connect the second valve assembly 26 with air bladders (not shown). Also not shown are air lines extending from the first valve assembly 24, through the suspension plate 16, and to air bladders (not shown). A fifth length 42 of air line 32 connect the air compressor 22 with the second valve assembly 26.

[0118] It is envisioned that the depicted suspension plate assembly 12 includes three air bladders arranged generally the same as or similar to what is depicted in FIG. 8, and accordingly the fourth length 40 of air lines 32 extend between these air bladders and the second valve assembly. It is also envisioned that the depicted suspension plate assembly 12 includes ten air bladders arranged generally the same as or similar to what is depicted in FIG. 3, and accordingly the first valve assembly 24 supplies these air bladders via air lines (not shown), which may extend through the suspension plate 16.

[0119] It is further envisioned that these different sets of air bladders, each providing a different function, such as one or a combination of lumbar support (prolonged inflation), kneading massage (low frequency cycle), or pulsation massage (high frequency cycle). By way of example, the air bladders supplied by the first valve assembly 24 may be adapted and configured for pulsation and the air bladders supplied by the second valve assembly 26 may be adapted and configured for lumbar support and / or kneading.

[0120] The suspension plate assembly 12 further comprises a blower 44 adapted and configured for ventilating the seat 10 to cool and / or draw moisture away from an occupant. The suspension plate 16 has a through-hole through which air generated by the blower 44 passes toward an occupant.

[0121] FIG. 2 illustrates a seat 46 comprising another exemplary suspension plate assembly 48 according to the present teachings. The suspension plate assembly 48 comprises a suspension plate 50 and a pulsation module 52 mounted thereon offset to the left of the centerline of the suspension plate 50 and the length thereof being generally vertically oriented. This provides an alternative arrangement for the air lines 54 extending from the pulsation module 52.

[0122] FIG. 3 is a perspective view of a seat 66. The seat 66 comprises a back portion 68 and a base portion 70. The back portion 68 and base portion 70 comprise air bladders 72 located underneath the cover or trim layer of the seat 66 (e.g., underneath the outermost fabric and / or leather layer).

[0123] FIG. 4 is a schematic of pneumatic components of an exemplary suspension plate assembly 74. The suspension plate assembly 74 comprises a pulsation module 76, compressor 78, valve assembly 80, air lines 82, and air bladders 84. The foregoing are all in pneumatic communication, which may be selective by virtue of the valve assembly 80 opening and closing connections via the air lines 82.

[0124] The pulsation module 76 includes pneumatic elements 86 and actuating elements 88. Thus, it can be seen that the pneumatic elements 86 are connected to the air lines 82 in a pressure-equalized manner and therefore to the air bladders 84 in a pressure-equalized manner. The pressure-equalized connection of pneumatic elements 86 to the air lines 82 and air bladders 84 are to be understood such that the total amount of air that is present therein remains constant when valves in the valve assembly 80 are closed.

[0125] The actuating elements 88 are configured to operate such that they can act upon the pneumatic elements 86 by way of a mechanical motion in order to bring about a change in the volume of the pneumatic elements 86. As described above, a pressure-equalized connection exists between pneumatic elements 86, air lines 82, and air bladders 84. If the volumes of the pneumatic elements 86 are changed, then, with a constant amount of air in the system (with a valve being closed), this leads to the pressure within the system changing. This can lead, for example, to further expansion of the air bladders 84 (i.e., a pressure increase) or also to a reduction in the volume of the pneumatic elements 86 or the pressure therein, respectively.

[0126] Periodic actuation of the actuating elements 88 leads to a periodic pulsation of the pneumatic elements 86. The pressures that causes changes in the volumes of the pneumatic elements 86 due to the actuation of actuating elements 88, moves at a speed that is less than or at most equal to the speed of sound, which, in the case of the dimensions of a seat, causes a substantially instantaneous transmission of this pressure and therefore also a corresponding change in the pressure conditions in air bladders 84, so that this pulsation can occur very quickly.

[0127] Each of the pneumatic elements 86 are connected to one air line 82 and thus to one air bladder 84 although the present teachings are not intended to be limited to this arrangement. For example, it can also be provided that a single pneumatic element 86 can be connected to a plurality of air bladders 84.

[0128] FIGS. 5 and 6 show a pulsation module 90 in the shape of a cylinder which is presently shown only in a cross-sectional view, where the image plane of FIG. 5 runs perpendicular to the longitudinal axis of the cylinder.

[0129] Pneumatic elements 92a-92d are arranged on the inner wall of the cylindrical form of the pulsation module 90. This can be implemented, for example, by adhesively bonding the pneumatic elements or some other mechanical attachment, such as mechanical fastening or clamping, as long as it is ensured that the pneumatic elements are closed in an airtight manner. Each of the pneumatic elements (shown by way of the example of pneumatic element 92a) is connected to an air bladder 94 via an air line 96 leading out of the pulsation module 90. The pneumatic elements 92a-92d preferably have the same shape and / or the same volume.

[0130] An actuating element 98 in the form of a roller is arranged in the pulsation module 90 and is arranged eccentrically to the longitudinal axis of the pulsation module 90 and that extends at least along a portion of the total length (perpendicular to the image plane) of the pulsation module 90.

[0131] The roller either has a cylindrical shape, although the present teachings contemplate slight deviations from a cylindrical shape. For example, deviations can be provided on the base surface and the top surface of the roller (corresponding to the base surfaces and top surfaces of the pulsation module 90, which for example, cause the roller to be beveled towards the base or top surface, respectively. For example, starting out from the center point of the roller, it can be provided that the radius of the roller reduces in the direction of the base or top surface, respectively. This can preferably be done in the formof a curve (such as a parabolic section) in order to prevent edges and thereby undesirable loads upon the air cushions.

[0132] The actuating element 98 rotates with its central axis 100 about central axis 102 of the pulsation module 90 when the actuating element 98 is in operation. Due to the eccentric arrangement of the actuating element 98, this leads to the pneumatic elements 92a-92d being deformed to different degrees when the actuating element 98 rotates about the central axis 100. As a result, pressure can be transmitted as a pulsation (with repeated and / or periodic rotation of the roller) via the air line 96 to the air bladder 94.

[0133] While the actuating element 98, illustrated as a roller, is arranged within the region in which the pneumatic elements 92a-92d are arranged, it can also be provided that the pneumatic elements 92a- 92d are surrounded by an actuating element 98 configured as a hollow roller in the pulsation module 90, where the pneumatic elements 92a-92d are then, for example, fixedly connected to a shaft extending along the central axis 102 of the pulsation module 90 to affix their position. The hollow roller then rotates eccentrically around the outside of the pneumatic elements 92a-92d and thus causes the desired deformation for generating the pulsation.

[0134] While the actuating element 88 shown in FIG. 5 comes into direct contact with the pneumatic elements 92a-92d, it can also be provided that spacers are arranged on the surface of the pneumatic elements 92a-92d facing the actuating element 98, for example, in the form of rubber elements or generally resilient elements with which the actuating element 98 interacts as it rotates to transmits a mechanical motion to a deformation of the pneumatic elements 92a-92d. This may reduce the wear on the surfaces of the pneumatic elements 92a-92d.

[0135] The contact surface of the pneumatic elements 92a-92d with the actuating element 98 may have a lubricant applied to it, such as lubricating grease, and / or that the pneumatic elements 92a-92d may be equipped with a thermoplastic polyurethane film on their contact surfaces so that friction with the interior surface of the pulsation module 90 may be reduced. The foregoing may allow for a reduction in the physical load on the pneumatic elements 92a-92d, so that their longevity can advantageously be increased.

[0136] Seams of the pneumatic elements 92a-92d may be arranged such that the physical load acting upon the seams are as low as possible. Such seams can be provided to close the pneumatic elements 92a-92d. The seams can be adhesively bonded, for example, by heating the material of which the pneumatic elements 92a-92d are made and in part melting it. If the seams were to run perpendicular to the image plane shown in FIG. 5, i.e., parallel to the central axis 102 of the pulsation module 90, then the pneumatic elements 92a-92d may be simultaneously loaded over their entire lengths along the seams by the motion of the actuating element 98. To avoid this, it can be provided that the seams, starting out from the upper end or the upper comer surface of the pulsation module 90 in the direction of the lower defining surface of the pulsation module 90, extends at least in part also in the circumferential direction so that it forms an angle with the central axis 82. This ensures that the entireties of the seams are notloaded at the same time when the actuating element 98 is rotated, but rather different regions of the seams are loaded at different rotational positions of the actuating element 98, which distributes the forces acting upon the pneumatic elements 92a-92d and thereby achieves improved service life of the pneumatic elements 92a-92d.

[0137] The inner diameter of the cylindrical portion of the pulsation module 90 may be about 10 cm or less, 7 cm or less, or even 5 cm or less. The inner diameter of the cylindrical portion of the pulsation module may be about 2 cm or more, or even 3 cm or more. The actuating element 98 and the pneumatic elements 92a-92d can then be sized according to the requirements, where the volume of the pneumatic elements 92a-92d may also depend on the number of pneumatic elements 92a-92d provided.

[0138] In principle, an electric motor 104, in particular a servomotor, can be provided as the drive for the actuating element 98. However, since the frequency with which the pulsation is to be generated in the pneumatic elements 92a-92d can, in part, deviate from the rotational frequencies that are customary for servomotors, it can be provided that a connection of the drive to the actuating element 98 is effected by way of a gear that realizes a certain transmission ratio.

[0139] Such an arrangement is shown schematically in FIG. 6. The electric motor 104 is provided and between the electric motor 104 and the cylinder with the pneumatic elements 92a-92d can be a gear 106, which causes a certain transmission ratio of the rotational speed of the electric motor 104 and the frequency of the actuating element 98.

[0140] FIG. 7 and FIG. 8 show an exemplary suspension plate assembly 108 according to the present teachings. The suspension plate assembly 108 comprises a suspension plate 110 upon which a variety of sub-components, described below, are mounted upon.

[0141] The suspension plate 110 includes suspension elements 112a-112f, functioning to connect the suspension plate 110 to the frame 114 of a seat. The suspension elements 112a-l 12f may be flexible to allow the suspension plate assembly 108 to flex with deformations in the seat, such as when the weight of an occupant is applied to the seat or the weight of an occupant shifts upon the seat. For example, the suspension elements 112a-l 12f may be in the form of wires or cables. The suspension plate 110 itself may also have a degree of flexure. The suspension plate 110 may be fabricated from polymer, such as an injection molded polymer. The suspension plate 110 is overmolded around the suspension elements 112a-l 12d. The suspension elements 112e-l 12f are looped around the suspension plate 110 at one end thereof and looped around the frame 114 at the other end thereof. The suspension plate 110 has a plurality of anchor points 116, into which connectors can be engaged to allow for alternative and / or additional mounting arrangements of connectors, connector assemblies, valve assemblies, air lines, power wires, signal wires, or any combination thereof.

[0142] The suspension plate assembly 108 comprises a pulsation module 118. The pulsation module 118 is located along a bottom edge of the suspension plate 110 and is oriented generally horizontally such that outlets of the pulsation module 118 are oriented to the left, although the present teachings contemplate any suitable orientation of the pulsation module 118 and directionality of the outlets. Asdescribed herein, the pulsation module 118 may be adapted and configured for providing pulses of air to air bladders for inflation of the same. The pulsation module 118 may be suitable for providing features such as tapotement-type massage therapy.

[0143] The suspension plate assembly 108 comprises a plurality of air lines 120 (e.g., 5 mm inner diameter tubes) connected at one end to the pulsation module 118. The air lines 120 are encapsulated by a sheath 122 for line management, precluding abrasion of the air lines 120, and contribute to an ease of installation. All of the air lines 120 extending from the pulsation module 118 are arranged in a first segment, and then are separated into two second segments to direct each of the second segments to a connector 124a, 124b. The air lines 120 may be routed along one side of the frame 114 to a top crossmember of the frame 114. In this regard, the air lines 120 and pulsation module 118 may be installed before the suspension plate 110 in the seat and the air lines 120 may hang from the top cross-member of the frame 114 and at some assembly step thereafter, the suspension plate 110 can be installed in the seat and the air lines 120 may be engaged with the connectors 124a, 124b. The connectors 124a, 124b can be pre-mounted on the suspension plate 110. In this regard, some air lines 120, such as those extending from the connectors 124a, 124b to a valve assembly 126 can be pre-assembled on the suspension plate 110 in one manufacturing step, and the sheathed air lines 120 may can be assembled to the suspension plate 110 at a later manufacturing step. The air lines 120 are also located in such a manner as to at least substantially avoid 90-degree bends therein, which may lead to kinking.

[0144] The valve assembly 126 is adapted to pneumatically communicate with air bladders adapted for pulsation (not shown). By way of example, these air bladders may have a similar configuration as those shown in FIG. 3. In this regard, air lines supplying said air bladders may extend through the suspension plate 110 and / or wrap around an edge of the suspension plate 110 (e.g., the bottom edge of the suspension plate 110). The suspension plate assembly 108 further comprises a valve assembly 128, configured to have pneumatic communication with air bladders 130a-130e. In this regard, air lines 120 extend between the valve assembly 128 and air bladders 130a-130e, and wrap around an edge of the suspension plate 110. It is understood that the air bladders 130d-130e are located upon separate plates that are adapted to located into bolsters of the seat.

[0145] In addition to the pulsation module 118, the suspension plate assembly 108 further comprises a compressor 132. It can be seen, by the arrangement of air lines 120, that the compressor 132 is pneumatically connected to both of the valve assembly 128 and the pulsation module 118. The air line 120 extending from the compressor 132 is connected to a splitter, which connects to two air lines that respectively pneumatically connect to both of the valve assembly 126 and the valve assembly 128. By this arrangement, the air bladders 130a-130e may be inflated and deflated independent of the air bladders (not shown) influenced by the pulsation module 118 and its associated valve assembly 126.

[0146] The valve assembly 126 and / or the valve assembly 128 can have a controller (not shown). Preferably, both of the valve assembly 126 and the valve assembly 128 have a controller. The controller functions, at least in part, to open and close valves according to one or more pre-determined programs,which may or may not be modified by an occupant. The controllers may be configured as a parent controller and a child controller. For example, the valve assembly 124 may have the child controller and the valve assembly 128 may have the parent controller, or vice versa. The parent and child controllers may communicate via a local interconnect network (LIN).

[0147] The suspension plate assembly 108 additionally comprises a blower 134, shown in the form of a radial blower. The blower 134 fluidly communicates with an aperture 136 formed in the suspension plate 110, and cooperates with the aperture 136 to direct an airflow upon the back of an occupant. It is envisioned that the airflow may travel through one or more channels formed in the seat (e.g., in the foam layer and optionally cover or trim layer).

[0148] FIG. 9A and FIG. 9B show an exemplary pulsation module 138 according to the present teachings. The pulsation module 138 includes a housing 140 that has a first segment 142 and a second segment 144 that fasten together around the internals of the pulsation module 138, such as shown in FIG. 5 and FIG. 6. The first and second segments 142, 144 are fastenable via snap-fit engagements 146 located on opposing sides thereof. As shown, the snap-fit engagements 146 are in the form of tabs on the first segment 142 that locates or snaps into engagement with openings on the second segment 144.

[0149] Outlets 148 adapted and configured to expel air are exposed through the housing 140. The outlets 148 can have features such as barbed fittings, push-to-connect fittings, threaded fittings, compression fittings, the like, or any combination thereof, to connect air lines to the outlets 148.

[0150] The housing 140 forms a wiring harness 150. The wiring harness 150 can be configured to deliver power and / or control signals to the pulsation module 138.

[0151] The housing 140 forms discs 152a, 152b defined by a dimension (e.g., a diameter), which are attached to stand-offs 154a, 154b defined by a dimension (e.g., a width), where the dimension of the discs 152a, 152b is greater than the dimension of the stand-offs 154a, 154b. The discs 152a, 152b and stand-offs 154a, 154b cooperate with channels (shown in FIG. 10A), discussed below.

[0152] The housing 140 forms fastener hole 156 that cooperates with a fastener (shown in FIG. 10A), discussed below.

[0153] The housing 140 forms feet 158a- 158c adapted and configured to receive grommets 160a- 160c, which may be fabricated from an elastomeric material. It is contemplated that the pulsation module 138 produces vibration and in this regard, the grommets 160a- 160c may dampen the vibration where the pulsation module 138 contacts another structural element of a suspension plate assembly or seat.

[0154] FIG. 10A through FIG. 10D show a cross-member 162 of a frame for a seat, such as a metal frame defining the structure of the seat. The cross-member 162 comprises channels 164a, 164b that cooperate with the discs 152a, 152b ofthe housing 112 ofthe pulsation module 110. The channels 164a, 164b have a first dimension commensurate with the dimension of the discs 152a, 152b and a second dimension commensurate with the dimension ofthe stand-offs 154a, 154b. The discs 152a, 152b enter the portion of the first dimension and slide down into the portion of the second dimension. The dimension of the discs 152a, 152b is greater than the second dimension, thus precluding removal of thediscs 152a, 152b from the channels 164a, 164b. A fastener 166 extends through the cross-member 134 and into the fastener hole 156 of the housing 140 of the pulsation module 138. The foregoing fastening means may secure the pulsation module 138 to the cross-member 162.

[0155] It is understood that the above description is intended to be illustrative and not restrictive. The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the invention, its principles, and its practical application.

[0156] Those skilled in the art may adapt and apply the invention in its numerous forms, as may be best suited to the requirements of a particular use. Many embodiments as well as many applications besides the examples provided herein will be apparent to those of skill in the art upon reading the above description.

[0157] Accordingly, the specific embodiments of the invention set forth herein are not intended as being exhaustive or limiting of the teachings. The scope of the invention should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.

[0158] The omission in the following claims of any aspect of subject matter that is disclosed herein is not a disclaimer of such subject matter, nor should it be regarded that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter.

[0159] The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes.

[0160] Plural elements or steps can be provided by a single integrated element or step. Alternatively, a single element or step might be divided into separate plural elements or steps.

[0161] The disclosure of “a” or “one” to describe an element or step is not intended to foreclose additional elements or steps.

[0162] The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.

[0163] Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints in increments of one unit provided that there is a separation of at least 2 units between any lower endpoint and any higher endpoint. As an example, if it is stated that the amount of a component, a property, or a value is, e.g., from 1 to 90, from 20 to 80, or from 30 to 70, it is intended that intermediate range values such as, e.g., 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc., are within the teachings of this specification. Likewise, individual intermediate values are also within the present teachings.

[0164] For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01, or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest endpoint and the highest endpoint enumerated are to be considered to be expressly stated in this application in a similar manner.

[0165] The term “consisting essentially of’ to describe a combination shall include the elements or components, and such other elements or components that do not materially affect the basic and novel characteristics of the combination. The use of the terms “comprising” or “including” to describe combinations of elements or components herein also contemplates embodiments that consist essentially of the elements or components.

[0166] While the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used to distinguish one element, component, region, layer, and / or section from another region, layer, and / or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer, and / or section discussed below could be termed a second element, component, region, layer, and / or section without departing from the teachings.

[0167] Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0168] The terms “generally” or “substantially” to describe angular measurements may mean about + / - 10° or less, about + / - 5° or less, or even about + / - 1° or less. The terms “generally” or “substantially” to describe angular measurements may mean about + / - 0.01° or greater, about + / - 0.1° or greater, or even about + / - 0.5° or greater.

[0169] The terms “generally” or “substantially” to describe linear measurements, percentages, or ratios may mean about + / - 10% or less, about + / - 5% or less, or even about + / - 1% or less. The terms “generally” or “substantially” to describe linear measurements, percentages, or ratios may mean about + / - 0.01 % or greater, about + / - 0.1 % or greater, or even about + / - 0.5 % or greater.
