FIG. 1 illustrates a seat assembly 30 according to an embodiment. The seat assembly 30 may be a vehicle seat assembly 30 for a land vehicle, aircraft, watercraft, or the like. The seat assembly 30 may be positioned in any seating row within the vehicle. The seat assembly 30 is illustrated with a seat bottom 32 that is adapted to be mounted within a vehicle. The seat bottom 32 is sized to support a pelvis and thighs of an occupant. The seat assembly 30 also includes a seat back 34 extending upright from the seat bottom 32. The seat back 34 is sized to support a back and shoulders of the occupant at pelvic, lumbar, and thoracic regions of the occupant.


The seat back 34 includes a frame 36 to provide structural support to cushioning and trim components 38 that are installed on the frame 36. The seat assembly 30 also provides various comfort and adjustment features, such as massage or pressure distribution. The seat assembly 30 may include a plurality of actuators such as air bladders 40 for imparting a pressurized effect upon the occupant. The air bladders 40 are supported in the seat assembly 30. The air bladders 40 may be supported directly, or indirectly upon the frame 36 of the seat back to face the seating surface of the seat back 34 and to impart the pressurized effect upon the seating surface. Likewise, the air bladders 40 may supported upon foam, a cushion, a trim component, or a suitable additional reactionary surface material. Although two air bladders 40 are illustrated, any combination or array of actuators 40 may be provided along the seating surface of the seat back 34. Likewise, a plurality of the actuators 40 may also be provided to impart the pressurized effect upon a seating surface of the seat bottom 32.


In order to operate the actuators 40, and provide a source of pressurized fluid, such as air, to the actuators, the seat assembly 30 includes a compressor 42. The compressor 42 is illustrated schematically beneath the seat bottom 32. The compressor 42 may be located anywhere within the seat assembly 30. The seat assembly 30 also includes a valve assembly 44 in fluid communication with the compressor 42 to receive the pressurized air from the compressor 42. The valve assembly 44 is also in fluid communication with the plurality of actuators 40 to relay the pressurized air to the actuators 40 as a pneumatic system. A controller 46 is also provided in the seat assembly 30 in electrical communication with the compressor 42 and the valve assembly 44 to control operation of the valve assembly 44.


Conventional valve assemblies 44 include a plurality of valves to perform a plurality of functions. Such pneumatic functions often include inflation and deflation, which can be utilized for massage, adjustment, comfort or the like. Valve assemblies 44 often have a dedicated valve per each function. Therefore, an increase in function often requires a significant increase in size, weight, and cost. Compactness is a goal of valve assemblies 44 in order to fit the valve assembly 44 within the seat assembly 30. Each valve within a valve assembly 44 often includes a solenoid, which each add significant cost and weight to the seat assembly 30. Additionally, weight reduction is often a goal in order to maximize fuel efficiency and/or energy efficiency of the associated vehicle. Therefore, a pneumatic system design may utilize a compromise or tradeoff between functionality and size/weight/cost.


The valve assembly 44 is illustrated schematically in FIG. 2 and exploded in FIG. 3. The valve assembly 44 includes a valve block 48. The valve block 48 is similar to prior art valve assemblies and includes a fluid outlet 50 for each valve within the valve block 48. Each valve within the valve block 48 may be a solenoid operated valve, a shape-memory alloy valve, or the like, as is known in the art.


The valve assembly 44 includes a multiplier assembly 52 to multiply a quantity of functional outputs of the valve block 48. The multiplier assembly 52 includes a plurality of fluid outlets 54 that is a multiplied factor of the quantity of outputs of the valve block 48. For example, the multiplier assembly 52 is a doubler, and therefore, the quantity of multiplier outlets 54 is double the quantity of the valve block outlets 50. The multiplier assembly 52 may be a multiplier of any factor, such as a tripler. The multiplier assembly 52 provides a doubled function without doubling the size of the valve block 48, thereby providing a reduction in size, weight, and cost in contrast to providing two valve blocks 48.


The multiplier assembly 52 includes a manifold 56 with a plurality of inlets 58 each corresponding to one of the valve bank outlets 50. Each multiplier inlet 58 receives pressurized air from the corresponding valve bank outlet 50. A pair of multiplier outlets 54 are aligned with each multiplier inlet 58 to provide two different outlets 54 for each inlet 58.


With reference again to FIG. 2, the multiplier assembly 52 also includes a valve body 60 oriented within the manifold 56. The valve body 60 includes an alternating series of ports 62 and elastomeric seals 64 to provide a series of valves, whereby the manifold 56 provides an integral series of manifolds 56. The valve body 60 has two linear positions relative to the manifold 56. In one position, such as a lower position in FIG. 2, the ports 62 align with a subset of, such as half of, the multiplier outlets 54 to open the first half of the multiplier outlets so that the pressurized fluid passes through the multiplier inlets 58, the manifold 56 and valve body ports 62, and then out through half of the multiplier outlets 54. In the first position of the valve body in FIG. 2, the seals 64 are positioned to disconnect the other half of the multiplier outlets 54 to close the second half of the multiplier outlets 54 from fluid communication with the multiplier inlets 58.


In a second position of the valve body 60, such as an upper position in FIG. 2, the ports 62 align with the other half of the multiplier outlets 54 so that the pressurized fluid passes through the multiplier inlets 58, the manifold 56 and valve body ports 62, and then out through the second half of the multiplier outlets 54. In the second position of the valve body in FIG. 2, the seals 64 are positioned to disconnect the first half of the multiplier outlets 54 from fluid communication with the multiplier inlets 58. According to an embodiment, the manifold 52 may be formed integrally with a housing 66 of the valve bank 48.


By doubling the functional output of the valve bank 48, a doubled output of the valve bank 48 may be utilized. For example, each of the multiplier outputs 54 may be in fluid communication to actuate different air bladders 40. The multiplier assembly 52 may be adjustable to two different modes. The modes may be arranged as modes that are not typically performed at the same time, for example the first position may be an adjustment mode for adjusting different zones in the seat assembly 30 by inflation and deflation. The adjustment operations may include lower lumbar, middle lumbar, high lumbar, thoracis, shoulder, left bolster, right bolster, and the like. Conversely, the second position may align with a massage mode for massaging various massage bladders 40 by inflation and deflation.


The multiplier assembly 52 performs as a valve switch multiplier assembly 52. The multiplier assembly 52 includes an actuator to actuate the valve body 60. The actuator may be linear, rotary (such as a rotary stepper motor), mechanical, pneumatic, electrical, a screw drive, or the like. FIG. 4 illustrates a linear pneumatic actuator 68 according to one embodiment. The actuator 68 includes a housing 70 with a pneumatic piston 72 received within a chamber 74 of the housing 70. A pair of ports 76, 78 are provided through the housing 70 and in fluid communication with the chamber 74. When air is received through the first port 76, the piston 72 is actuated downward to the first position while air is exhausted from the chamber 74 out of the second port 78. Pressurized air ingresses the second port 78 to shift the piston 72 upward to the second position, while air egresses the first port 76. The piston 72 is connected to the valve body 60 to actuate the valve body 60 to the first and second positions. Alternatively, the piston 72 may be formed integrally with the valve body 60.



FIG. 5 illustrates an alternative linear actuator 80 for actuating the valve body 60. The actuator 80 includes a piston 82 within a chamber 84 of a housing 86. A pair of magnets 88, 90 are provided at opposed ends of the piston 82. A pair of electromagnets 92, 94 are provided on the housing 86. Application of a current to either electromagnet 92, 94 repels the corresponding magnet 88, 90 to drive the piston 82 to an opposed position. A reverse current can be applied in the opposite electromagnet 92, 94 to attract the corresponding magnet 88, 90 to shift the position of the piston 82. A combination of both features may be employed with a current in the repel direction in the first electromagnet 92 to repel the first magnet 88 and a current in the attract direction in the second electromagnet 94 to attract the second magnet 90 to shift the piston 82 downward to the first position. Conversely, the current in the attract direction can be applied to the first electromagnet 94 while the current in the repel direction is applied to the second electromagnet 94 to shift the piston 82 upward to the second position. Alternatively, the piston 82 may be formed integrally with the valve body 60.


Another linear actuator 96 is illustrated in FIG. 6 for shifting the valve body 60. The actuator 96 includes a housing 98 with a chamber 100 for receipt of a piston 102. The actuator 96 includes a solenoid 104. Upon application of a current to the solenoid 104, an electromagnetic coil in the solenoid 104 repels a magnet on a rod 106 thereby shifting the rod 106 and the piston 102 upward to the second position. Removal of the current permits an internal spring within the solenoid 104 to retract the shaft 106 and shift the piston 102 downward to the first position. Alternatively, the spring may be located within the chamber 100 and outside the solenoid 104. According to another embodiment, a reverse current may be applied to the solenoid 104 to attract the magnet to retract the shaft 106 to shift the piston 102 downward. According to another embodiment, the piston 102 may be formed integrally with the valve body 60.



FIGS. 7 and 8 illustrate a multiplier assembly 110 according to another embodiment. The multiplier assembly 110 includes an inlet housing portion 112. The inlet housing portion 112 includes a substrate 114 that forms an inlet manifold with a plurality of ports 116 extending from the substrate 114 as inlets 116. The inlets 116 are provided incrementally spaced and in a linear array. Each inlet 116 is provided with radial symmetry for attachment of tubing to convey fluid into the manifold of the multiplier assembly 110.


The multiplier assembly 110 also includes an outlet housing portion 118. The outlet housing portion 118 includes a substrate 120 that forms an outlet manifold with a plurality of ports 122 extending away from the substrate 120 as outlets 122. The outlets 122 are provided incrementally spaced and in a linear array. Each outlet 122 is provided with radial symmetry for attachment of tubing to convey fluid from the manifold of the multiplier assembly 110. The outlets 122 have a quantity that is a multiplied factor of the inlets 116. For example, there are two outlets 122 for each inlet 116.


A cavity 124 is provided in each substrate 114, 120 to collectively provide a fluid chamber for the manifold formed collectively by the inlet housing portion 112 and the outlet housing portion 118. Each of the housing portions 112, 118 may be formed from a structural material, such as a structural polymer. A plurality of retainers 126 are provided on the substrate 114 of the inlet housing portion 112. Each retainer 126 includes a flexible body with a central receptacle. A corresponding plurality of retainers 127 extend from the substrate 120 of the outlet housing portion 118. Each retainer 127 includes a leading edge and an abutment edge. During assembly of the housing portions 112, 118, the leading edge of the retainers 127 engage the flexible bodies of the retainers 126 to deflect the retainers 126 until the abutment edge aligns with the receptacle, whereby the flexible members retract with the abutment edge within the receptacle to retain the fasteners 127 within the retainers 126.


Referring now to FIG. 8, the multiplier assembly 110 includes a valve bar 128 received within the cavity 124 in the substrates 114, 120. The valve bar 128 has a series of ports 130 formed therethrough. A series of seals 132 are mounted to the valve bar 128. According to an embodiment, the seals 132 may each be provided as O-rings 132. The seals 132 cooperate with the ports 130 and the substrates 114. 120 so that at each position of the valve bar 128, each valve bar port 130 is in fluid communication with an associated inlet 116 and sealed off from the other inlets 116. The seals 132 also cooperate with the ports 130 and the substrates 114, 120 so that at one position of the valve bar 128, each valve bar port 130 is in fluid with a first outlet 122 and isolated from the other outlets 122. The seals 132 cooperate with the ports and the substrates 114. 120 so that at a second position of the valve bar 128, each valve bar port is in fluid communication with a second outlet 122 and isolated from the other outlets 122.


With reference now to FIGS. 7 and 8, the multiplier assembly 110 includes a linear actuator 134, which according to an embodiment, is an electric motor based linear actuator 134. According to another embodiment, the actuator 134 is a solenoid 134. The actuator 134 includes a housing 136 with a pivot or clevis bracket 138. A corresponding clevis bracket 140 extends from the substrate 120 of the outlet housing portion 118. The clevis bracket 138 of the actuator 134 is pivotally connected to the clevis bracket 140 of the inlet housing portion 118 to support the actuator 134. The actuator 134 is operated to extend and retract a shaft 142 relative to the solenoid housing 136. A distal end of the shaft 142 is pivotally connected to a shift extension 144 of the valve bar 128 so that extension and retraction of the solenoid shaft 142 shifts the valve bar 128 between the first position and the second position.


The valve block switching mechanism 110 can turn the eleven-function modular valve bank 48 into a twenty-two function valve bank 48, 110 without doubling the size of the valve bank 48. The doubled functionality is provided by adding one more actuator, instead of eleven more actuators. Referring again to FIG. 1, the seat assembly 30 may employ two valve assemblies 44, wherein the functionality of each valve assembly 44 is multiplied without a double to size, weight, or cost.



FIGS. 9-12 illustrate a multiplier assembly 150 according to another embodiment. FIGS. 9 and 10 illustrate the multiplier assembly 150 in a first position, and FIGS. 11 and 12 illustrate the multiplier assembly 150 in a second position.


The multiplier assembly 150 includes an inlet housing portion 152. The inlet housing portion 152 includes a substrate 154 that forms an inlet manifold with a plurality of ports 156 extending from the substrate 154 as inlets 156. The inlets 156 are provided incrementally spaced and in a linear array. Each inlet 156 is provided with radial symmetry for attachment of tubing to convey fluid into the manifold of the multiplier assembly 150.


The multiplier assembly 150 also includes an outlet housing portion 158. The outlet housing portion 158 includes a substrate 160 that forms an outlet manifold with a two series of ports 161, 162 extending away from the substrate 160 as outlets 161, 162. The outlets 161. 162 are provided incrementally spaced and in a linear array. Each outlet 161, 162 is provided with radial symmetry for attachment of tubing to convey fluid from the manifold of the multiplier assembly 150. The outlets 161, 162 have a quantity that is a multiplied factor of the inlets 156. For example, there are two outlets 161, 162 for each inlet 156.


A plurality of sidewalls 164 extend from the base or substrate 154 of the inlet housing portion 152 to engage a plurality of sidewalls 166 that extend from the base or substrate 160 of the outlet housing portion 158. A cavity 168 is provide collectively within the substrates 154, 160 and the sidewalls 164, 166 to provide a fluid chamber for the manifolds. Each of the housing portions 152, 158 may be formed from a structural material, such as a structural polymer. During assembly of the housing portions 152, 158, the sidewalls 166 of the outlet housing portion 158 are inserted into the sidewalls 164 of the inlet housing portion 152. The sidewalls 166 are sealed to the sidewalls 164 by fasteners, adhesives, welding or the like.


The multiplier assembly 150 includes a valve bar 170 received within the cavity 168 in the housing portions 152, 158. The valve bar 170 cooperates with the housing portions 152, 158 to pivot and translate relative to the manifolds in the housing portions 152, 158. A plurality of radial extensions 172 extend from the valve bar 170 as paddles 172. An elastomeric seal 174 is provided on each of the radial extensions 172.


The first inlet housing portion 152 includes a slot 176 formed therethrough. The slot 176 is angled relative to an axial direction of the valve bar 170. A pin 178 extends radially outward from the valve bar 170. The pin 178 is received in the slot 176. The angled slot 176 provides cam surfaces whereby the pin 178 is a cam follower to convert linear motion to rotary motion. For example, as the valve bar is shifted linearly from a lower position in FIGS. 9 and 10 to an upper position in FIGS. 11 and 12, the pin 178 follows the slot 176 thereby pivoting the valve bar 170 counterclockwise from FIGS. 10 to 12. A return motion of the valve bar 170 downwards from FIGS. 11 and 12 to FIGS. 9 and 10, causes the pin 178 to follow the slot 176 whereby the shaft 170 rotates clockwise from FIG. 12 to FIG. 10. A linear actuator may be provided as the input of linear motion. Alternatively, a rotary actuator may be employed, whereby the pin 178 and slot 176 cooperate to convert the rotary motion to linear motion.


At the lower position of the valve bar 170 in FIGS. 9 and 10, the seals 174 close one column of outlet ports 161 as illustrated in FIG. 10. Likewise, the seals 174 open the other column of outlets 162 so that air from each inlet 156 is directed through the outlet 162. When valve bar 170 is shifted to the upward position of FIGS. 11 and 12, the air is redirected to the other mode of outlets 161 instead of the outlets 162. FIG. 12 illustrates that the seal 174 is retracted from, to open, the outlets 161 while the opposed seal 174 is seated against the port 162 to close the ports 162. The rotation of the valve bar 170 can be optimized, such as at ten degrees for example, so that the valve bar 170 and seals 174 operate as a twist-gate valve assembly.



FIGS. 13 and 14 illustrate a multiplier assembly 190 according to another embodiment. The multiplier assembly 190 includes a housing 192 with a fluid chamber 194. The housing 192 defines a plurality of manifolds for the valve assembly 44. The housing 192 includes a plurality of inlets 196, 198, 200 in fluid communication with the fluid chamber 194. The inlets 196, 198, 200 are provided incrementally spaced and in a linear array. The housing 192 includes a plurality of outlets 202, 204, 206, 208, 210, 212 in fluid communication with the fluid chamber 194. The outlets 202, 204, 206, 208, 210, 212 are provided incrementally spaced and in a linear array. The outlets 202, 204, 206, 208, 210, 212 have a quantity that is a multiplied factor of the inlets 196, 198, 200. For example, there are two outlets 202, 204, 206, 208, 210, 212 for each inlet 196, 198, 200.


The multiplier assembly 190 includes a valve bar 214 received within the chamber 194. A series of seals 216 are mounted to the valve bar 214. According to an embodiment, the seals 216 may each be provided as O-rings 216. In a first mode, depicted by an upward position of the valve bar 214 in FIG. 13, the seals 216 provide fluid paths between the inlets 196, 198, 200 and three of the outlets 202, 206, 210 respectively. Likewise, in the first position, the seals 216 isolate the outlets 204, 208, 212. A second mode is provided by the downward position of the valve bar 214 in FIG. 14. In the downward position, the valve bar 214 is shifted such that the seals isolate the outlets 202, 206, 210 to prevent the pressurized air from passing out of the outlets 202, 206, 210. In this position, the seals 216 provide fluid paths for the air to pass from the inlets 196, 198, 200 through the chamber 194 and out of the outlets 204, 208, 212 respectively. Although three inlets 196, 198, 200 and six outlets 202, 204, 206, 208. 210, 212 are illustrated any multiplier of outlets may be employed. Additionally, any number of inlets 196, 198, 200, such as eleven inlets may be input and multiplied.
