Description

COMFORT TEMPERATURE REGULATING COMPONENT SYSTEMCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of PCT Application PCT / US22 / 48234, filed on October 28, 2022, which claims the benefit of Provisional Patent Application number 63 / 272,972, filed on October 28, 2021, under 35 U.S.C. 119(e) and is a Continuation in Part (CIP) of US National Stage Application 18 / 705,379, filed on April 26, 2024.

[0002] The entire contents and description of the parent, US patent application number 18 / 705,379 is incorporated herein by reference in its entirety.PRIOR ART

[0003] It is well accepted that exposure to outer elements can ruin components if they become wet. In order to avoid water saturation, conventional types of rain covers have been promoted to solve the problem of water and snow exposure. Prior attempts have included rain covers and roofing.BACKGROUND OF THE INVENTION

[0004] 1. Field of the Invention The present invention relates to a new weather resistant comfort temperature regulating component, such as an exposed vehicle seat, and more particularly, the invention relates to a number of aspects including a weather resistant air flow distribution system for heated and cooled components that will not be harmed when rained or snowed upon.

[0005] 2. Description of the Prior Art Clearly, conventional outdoor exposed components, especially those on vehicle seats for motorcycles and the like that are exposed to the outer elements get wet in the rain. In order for heating and cooling of a seat to be especially effective, perforations in the outermost seating cover provide any heated and / or cooled air to comfort an occupant of the seat. However, it creates aproblem because rain and snow can enter into the heating and cooling system electronics through those same perforations. Full coverage waterproof materials have been promoted to solve the problem of rain saturated seat materials. However, now that vehicle operators have become accustomed to heated and cooled car seats, they also want heated and cooled seats for their other vehicles, like agricultural vehicles, motorcycles, golf carts, marine applications and boats, along with other types of applications where their components are exposed to rain and snow, whether the application is a permanent solution or an accessory that is removably attachable.

[0006] However, in one important aspect of the present invention, the heated and cooled seats are covered with materials that are generally perforated to allow for contacting warmed and cooled air to the seat occupant. It is common sense that those perforations in the seat material would allow rain or snow to flow through the outermost seating material into the underlying seat material and components. That exposure to rain and wash water would obviously cause problems with heating and cooling components, especially their electrical wiring and motors.

[0007] Therefore, it would be an advantage to the industry if a heated and cooled permanent or aftermarket seat could comfort an occupant even after being exposed to the outer elements. This is the problem that the present invention addresses.SUMMARY OF THE INVENTION

[0008] In accordance with the above-noted advantages and desires of the industry, the present invention provides several aspects of semipermanent and permanent installations of a comfort temperatureregulating component system with a weather resistant air flow distribution system and exposed seating ventilation perforations that overcomes the barrier of using a ventilated solution for the cooling and heating of components contacting occupants in outdoor environments or thoseenvironments that experience exposure to the outer elements with the presence of water or other foreign liquids. The invention is also less expensive to manufacture and much simpler to install into a conventional component such as an outdoor vehicle seat whether semi-permanent or permanent. The present invention is applicable to many other applications including other heat and cooling systems, whether permanently a part of the component system or as an aftermarket strap-on application. Consequently, the descriptions herein shall be covered for any application, including thermoelectric based systems that heat and cool or a resistance heater based system.

[0009] In most of the aspects of the present invention, the invention incorporates a small, high flowrate, high pressure blower to force air through openings in the component surface. Prior to and directly adjacent to the component surface, a variety of valves may be used to allow air to flow toward the seat occupant but not allow liquids to flow back in from the environment. In particular, a one-way valve allows passage of air from the blower, through ducting or tubing in the seat cushion and then to the seat surface with low pressure drop on the blower to maximize air flow to the seat occupant. The valve is spring loaded and blocks the flow of liquid or other foreign material into the air distribution system when the blower is not in operation. In addition, the air exit at the seat surface can be covered in a hydrophobic mesh that allows passage of cooling air but resists water. In addition, a P-shaped water trap can be added at the bottom of the air sweep that brings the air to the final exit point on the seat.

[0010] At the seat surface, the exit openings can be used alone or with the hydrophobic mesh. Especially useful is an added expanded mesh material, sometimes called 3D spacer mesh that can be used to cover the air openings so as to provide a dispersed air flow medium under the seat occupant which also prevents the possible blocking of the air openings by leather pants or the like. An alternative aspect to ensure the air flow to theseat occupant is not blocked or impaired, is the use of air passageways molded or impressed into or onto the seat cover. Heating can be added to the system with the addition of a low cost resistance heater element placed in the air flow stream.

[0011] To improve the evaporative performance of the flowing air over the seat occupant's skin and aiding cooling, a desiccant canister can be added to the system air flow stream to provide desiccated air to the seat occupant. Two or more desiccant canisters can be used in combination with air diverter valves to allow for the recharging of one canister while the other canister is in use.

[0012] Another aspect of the invention is to use a thermoelectric cooling and heating assembly inline with the air stream to cool or heat the air prior to distribution to the seat surface. In this aspect, the air that is drawn into the blower flows through a heat sink that is being cooled or heated by a thermoelectric device. This thermally conditioned air exits the heat sink and is then distributed to the surface of the seat or other body contact item. Systems exist using this same concept but not for distribution in a water resistant system designed to be used in outdoor environments. The existing systems are open air systems that allow water or other fluids to infiltrate through the seat cover and into the working of the seat cooling and / or heating system. The different construction options can be used together or separately.

[0013] In harsh environments, such as motorcycle seating or off-road vehicle seating, splashing and submersion in water is possible. Though the ingress of water and water borne debris is prevented from entering the seat occupant portion of the system via the one-way valves and hydrophobic mesh, it is still possible, during splash or immersion events, water could enter the fan intake.

[0014] Two aspects of the invention block the above noted ingress of water, or other contaminants. The first is a splash guard that allows forairflow to the blower intake but deflects splash. The other is a float valve mechanism that blocks ingress with the "floating" of a low density member into a sealing position of the blower intake.

[0015] Other applications for the present invention may include other uses such as pet beds, stadium seating, medical bedding requiring wash down, improved automotive seating, bicycle seats, construction & agricultural seats, beds, chairs, whether home or office, sofas, operating tables, and even small animal enclosures, etc. Because these applications are exposed to rain, wash water, splashing and the like, it is a real advantage to provide a weather and liquid resistant covering for electronics and machinery under the outermost material.

[0016] Controlling body heat in individuals is important in maintaining optimum body performance and comfort. In recognition of this, many homes, offices, workplaces, automobiles, etc. are conditioned to maintain a certain temperature with heating, cooling and ventilation systems. In automotive settings, heated seats, cooled seats and ventilated seats are commonly available. These systems provide heating and cooling to seat occupants providing a comfortable seated experience.

[0017] The most common of the heating systems for seating are electrical resistance mats for heating. These systems are relatively inexpensive and have been used for many years. The heated mats use thermal conduction to move the heat energy they produce to the occupant.

[0018] Combined heating and cooling systems often use a thermoelectric device to pump heat to a thermal delivery heatsink for heating a seat occupant or cooling a thermal delivery heat sink for cooling a seat occupant. Most such systems rely on the cooling or heating of air that is then distributed to the seat occupant via perforations in the seat.

[0019] Another system using a thermoelectric device is similar to those using air as the thermal distribution medium, instead uses a conductive material to transport the heat to or from the seat occupant. Thisconductive material lies beneath the seat surface and conducts heat or coolness to the seat occupant.

[0020] One of the most common systems in automobiles to aid in the cooling of people sitting in seats, is to force air through perforations in seats. This moving air is like a breeze that aids in evaporating skin moisture, which, in turn, cools the body. This system is less costly than thermoelectric device based systems because it consists primarily of a fan or blower and ducts that provide air to the perforations in a seat.

[0021] For cooling seat occupants, the systems previously noted can work rather well. These systems, are, however expensive and difficult to package in the small amount of space associated with seats. In the case of the systems using perforations, water, beverages, dirt and dust can infiltrate the holes, causing obstructions in the small diameter perforations, and allowing fluids to get into the seat structure providing an environment for the possible growth of biological organisms. These perforated systems cannot be used in outdoor environments where water and other foreign materials can infiltrate the porous layers of the system. Along with the potential for biological growth should water or other liquid or muddy material enter the seat via the perforations, in some environments, water could infiltrate the system and cause damage to components such as blowers or thermoelectric devices. This is why motorcycle seats, off-road vehicle seats, heavy equipment seats, farm tractor seats, boat seats, etc., do not use perforated or ventilated seats.

[0022] The invention is particularly useful for applications in the industries that require a person to be seated for some period of time in hot environments that are exposed to outdoor weather. Examples include, construction equipment, motorcycles, off-road vehicles, utility vehicles, side-by-side recreational vehicles, farm equipment, military vehicles, aviation, child car seats, wheelchairs, animal bedding, etc. The applications are too numerous to mention here.

[0023] Although the invention will be described by way of examples hereinbelow for specific aspects having certain features, it must also be realized that minor modifications that do not require undo experimentation on the part of the practitioner are covered within the scope and breadth of this invention. Additional advantages and other novel features of the present invention will be set forth in the description that follows and in particular will be apparent to those skilled in the art upon examination or may be learned within the practice of the invention. Therefore, the invention is capable of many other different aspects and its details are capable of modifications of various aspects which will be obvious to those of ordinary skill in the art all without departing from the spirit of the present invention. Accordingly, the rest of the description will be regarded as illustrative rather than restrictive.BRIEF DESCRIPTION OF DRAWINGS

[0043] In accordance with the present invention, comfort temperature regulating component weather resistant heating and cooling system is disclosed for incorporation into a perforated surface, especially useful for heated and / or cooled seats and / or ventilated seats that are desiccated that are used in motorcycles, golf carts, snowmobiles, all terrain vehicles (ATV's), boats, and any other seating type of application. As one can imagine, such seating applications are usually exposed to the outer elements, including rain and / or snow, and since perforated leather or its synthetic counterpart are generally prescribed to allow the heated, cooled, or desiccated air to come up through the seat to comfort a passenger, it is necessary to essentially waterproof the seat. In that regard, the presentinvention provides a means for making a perforated seat to be weather resistant enough so as to functionally waterproof the seat, or any other application requiring weather or water resistance.

[0044] The most common of the heating systems for seating are electrical resistance mats. These systems are relatively inexpensive and have been used for many years. The heated mats use thermal conduction to move the heat energy they produce to the occupant.

[0045] Combined heating and cooling systems often use a thermoelectric device to pump heat to a thermal delivery heatsink for heating a seat occupant or to cool with the use of a thermal delivery heat sink for cooling the seat occupant. Most of these systems rely on the cooling or heating of air that is then distributed to the seat occupant via perforations in the seat.

[0046] Another aspect includes using a thermoelectric device similar to those using air as the thermal distribution medium, but instead uses a conductive material to transport the heat to or from the seat occupant. This conductive material lies beneath the seat surface and conducts heat / cool to or from the seat occupant.

[0047] One of the most common systems in automobiles to aid in the cooling of people sitting in seats, is to force air through perforations in seats. This moving air is like a breeze that aids in evaporating skin moisture, which, in turn, cools the body. This system is less costly than thermoelectric device based systems because it consists primarily of a fan or blower and ducts that provide air to the perforations in a seat.

[0048] For cooling seat occupants, the systems previously noted can work rather well. These systems are, however, expensive and difficult to package in the small amount of space associated with seats. In the case of the systems using perforations, water, beverages, dirt and dust can infiltrate the holes, causing obstructions in the small diameter perforations, and allowing fluids to get into the seat structure providing an environment for the possible growth of biological organisms.

[0049] These perforated systems generally cause problems when used in outdoor environments where water and other foreign materials can infiltrate the porous layers of the system. Along with the potential for biological growth should water or other liquid or muddy material enter the seat via the perforations, in some environments, water could infiltrate the system and cause damage to components such as blowers or thermoelectric devices. This is why motorcycle seats, off-road vehicle seats, heavy equipment seats, farm tractor seats, boat seats, etc., do not use perforated or ventilated seats.

[0050] In order to control these functions in the abovementioned aspects, it will be useful to incorporate various controls. Such controls may include a direct ON / OFF electrical switch; a pulse width modulated control for blower, heater and thermoelectric device; and a microprocessor logic control plus pulse width modulated to speed up or slow down blower air based on preset operational parameters.

[0051] A controller finds great utility in order to allow more or less electrical energy for powering the resistance heating device based on preset parameters as well as to allow for controlling heating or cooling by changing the polarity of the thermoelectric device and adjusting the amount of electrical energy to the device. An example of this operation entails the sensing of the outside temperature and adjusting blower, blower plus heater, or blower plus thermoelectric device, to keep the seat occupant comfortable based on set operational parameters loaded into the microprocessor. Further, temperature control may be accomplished by the use of a thermistor placed at the air outlet, or somewhere within the outlet air flow duct of the heater or on the heater. Other aspects include using a thermistor placed at the outlet or somewhere within the outlet air flow duct of the thermoelectrically heated or cooled heat sink or on the heat sink.

[0052] Yet another aspect includes a temperature sensing device, such as a thermistor, which can be placed near the seat surface. This is primarilyused to monitor the temperature so as to not allow the temperature to exceed a set temperature for the safety of the seat occupant.

[0053] Therefore, disclosed is a weather resistant comfort temperature regulating component system, comprising a preferred aspect of at least a ventilated seat cushion cover secured over a seat cushion with an air flow distribution system inside. Air ducts inside the seat cushion direct the air being distributed. In order to prevent infiltration of liquids from outside, disclosed herein is a number of one-way valves that direct the conditioned air out of air exits toward the seat occupant. In order to direct the air through exits toward the seat occupant, a blower is included, preferably with a high flow rate, high pressure blower motor. Weather resistant mesh covers over the air ducts help to keep the seat cushion dry even when it rains or the seat is washed. The weather resistant covers preferably include some sort of hydrophobic material that repels water, dirt and dust but allows air flow, such as a water resistant mesh such as Frogzskin, covering over the air exits.

[0054] The comfort temperature regulating component system will resist water infiltrating any heating system within the seat to achieve a comfortable temperature. Including a low-cost resistance heater is preferred to be placed in the airstream within the air flow distribution ducts that are in communication with the blower. In addition, further comfort can be achieved by the use of an in-line desiccant container added to the air flow stream within the air flow distribution ducts. Merely blowing dry air at a seat occupant adds comfort.

[0055] Referring now to the drawings in detail, FIG. 1 is a perspective environmental view of a motorcycle generally indicated by the numeral 10, which also includes a semi-permanent aftermarket strap-on version of a seat pad 12 made in accordance with the present invention. A seat occupant 14 guides his motorcycle 16 while being comforted by seat pad 12. Although the present invention is described in terms of seating add ons, many of the aspects can act as an aftermarket accessory to be addedon top of an existing seat that can comfortably be used due to its low profile dimensions. Due to the low profile, it is unlikely to impede the occupant getting on and off a seat. As such, the present invention is to include a separate device that can be strapped onto, or otherwise attached to, an existing seat as described more fully hereinbelow.

[0056] FIG. 2 shows a motorcycle seat 20 having a pair of seat pads 22 which accommodate a motorcycle rider and a passenger on a pillion. Seat pads 22 have a raised rearward portion acting as somewhat of a seat back and enclosure for electronics and blowers in accordance with the present invention. An overview of the structure includes a foam "bun" seat pad, with a waterproof material over the bun that may be a thin polyester film. On the bottom and possibly a little up the sides and over the rear area, is the seat covering, often a waterproof vinyl. On top of the foam bun seat pad is the 3D mesh where a person contacts the pad. The air flows out of the one-way valve and disperses into the 3D mesh, sometimes called a spacer material and flows over the posterior of the seat occupant. The foam seat bun is waterproofed by the waterproof film. The 3D mesh is preferably mostly found in the seating area. The 3D mesh area 26 that allows air to flow from the one-way valve exits to the seat occupant. This allows water to flow through as well. The water is kept out of the air distribution system by the one-way valve. Water is kept from the foam bun seat by the foam bun seat being fully encased in a waterproof film, over which the seat covering and 3D mesh are placed.

[0057] Electronic controller 28 is located at the bottom of seat pad 22 for easy access by a passenger such that the passenger can control the amount of heat or coolness they desire. Seat bottom covering 30 may be of any suitable non-slip material, so that the seat pad does not slip around while riding. In a larger model motorcycle seat example, the accessory seat pads 22 have a seat pad installed permanently or as an accessory seat pad covering. A raised portion seat back 24 will be of a sufficient type to house the operative portions of the present invention.

[0058] FIG. 3 shows a water resistant seat assembly generally denoted by numeral 34. A vinyl or other appropriate seat covering 36 on the seat back rest emanating outwardly from the seat back rest includes a power cord 38 having a connector to be plugged into the power supply of the motorcycle.

[0059] In addition, an electronic controller 40 extends outwardly from the seat back rest that can be easily reached by the seat occupant. Seat covering 42 is preferably a hydrophobic 3D mesh material that allows air to pass therethrough while still being water resistant. Although the 3D mesh can be itself hydrophobic but given the large free space between mesh strands, water will get in. The water is kept out of the foam bun seat pad by the waterproof film and out of the air flow mechanicals by the one-way valve which will be described more fully hereafter.

[0060] FIG. 4 illustrates a strap-on cooling and heating pad generally denoted by numeral 50 including a heater 52 controlled by electronic controller 54 and blower 56. Extending outwardly from blower 56 is air distribution tube 58 terminating in a one-way valve 60 providing an air exit point through air groove 62. The groove in the seat pad is the main preferred air distribution site. Since the seat pad is conventionally made of foam is carved out to create the groove. In the lower area of the groove a weep hole 68 exits any water from condensation or from the outside environment. A foam bun seat pad 64 provides a comfortable seat for its occupant and is covered with a suitable material that is water resistant, such as a polyethylene waterproof seating film, preferably a 3D mesh 66. A useful weep hole 68 helps to disburse any liquid collecting therein.

[0061] It may be useful to know that a horizontal air distribution approach may be preferred to horizontal and vertical air distribution for efficiency, thereby distributing the heat and coolness across a greater surface to comfort a seat occupant.

[0062] FIG. 5 is an underside view of an air intake 50 showing air heater 52 embedded into foam bun seat pad 64. Blower 56 is shown in phantomattached to air distribution tube 58 such that blower 56 urges air through air distribution tube 58 into air heater 52 in this aspect of the present invention. In other aspects, as will be more fully described herein below, air heater 52 may also include the use of resistance heaters, such as a heated mat or spiral heater. Other aspects utilize a thermoelectric device to provide both heating and cooling of the seat for passenger comfort. In this aspect, there is also a weep hole 68 to provide an exit for any condensate or collected liquid. As before, power cord 70 terminates with an electrical connector to be plugged into the power supply of the motorcycle. This power cord 70 is recessed into an electrical connection pocket 72. To supply air to blower 56, air intakes 74 are preferably on both sides of the foam bun seat back, one on the seat side and a second air intake on the back side in case the one on the seat side is blocked by a seat occupant. A non-slip surface 78 on the bottom of the seat pad 50 is to prevent the strap-on seat from sliding.

[0063] FIG. 6 is a more detailed illustration of preferred air intake in the seat pad generally denoted by the numeral 50, and includes a power cord 70 with electrical connectors to supply power to the controller, which in turn supplies power to the blower or to the heater and / or thermoelectric system. Air intake 74 includes in this aspect a rear air intake 72 and a side air intake 74. Air passage 80 will be located on the side of seat pad 50 such that if rear intake 72 is blocked, side air intake 74 can provide air flow to the blower.

[0064] FIG. 7 is a more detailed illustration of rear and side air intakes 72 and 74 respectively. Blower 56 is fed air through air passage 80 via air inlets 72 and 74 which are covered by air permeable hydrophobic mesh 82 to resist water entering the blower. Air groove 84 is shown in position.

[0065] FIG. 8 generally shows strap-on seat pad denoted by numeral 90 showing the relative placement of straps 92 to hold seat pad 96 in position to allow for the seat pad to be secured to an existing seat.

[0066] FIG.'s 9A and 9B show an alternative configuration to a seat pad made in accordance of the present invention showing a resistance heater 100 in line from an air blower 102 and being temperature controlled by electronic controller 104. An air distribution tube 106 urges heated air through one-way valve 108. Consequently, electronic controller 104 determines the heat level desired by the seat occupants which blower 102 delivers air supply through heater 100 before it goes through air distribution tube exiting through one-way valve 108 exiting through the seat air groove 112 to comfort the seat occupant. With the heater energized, the blowing air is used to warm the seat occupant.

[0067] An alternative aspect for providing heated and cooled air utilizes a thermoelectric device inline downstream from the blower motor, wherein heated and cooled air pass there over, thereby heating and cooling the air which will eventually reach the seat occupant. The openings in the 3D mesh seat aid to deliver this heated and / or cooled air through the seat cushion cover to be felt by the seat occupant.

[0068] In order to further prevent water from entering the seat through the perforations, a splash guard will be useful to allow for airflow to the blower intake while deflecting splash. Further, a float valve mechanism is also envisioned that blocks ingress by the floating of a low density member into a sealing position of the blower intake.

[0069] The disclosed comfort temperature regulating component system includes a weather resistant ventilated assembly including a ventilated component system cover that prevents damage from the outer elements. This system is equally proficient for both permanent installations and as an aftermarket accessory for most applications, especially seating. Preferably, a component system to be protected from outside elements is to be located under said component system cover. An air flow distribution system includes air ducts and air exits to direct forced air, or heated or cooled air streams generated from the comfort temperature regulating component system to comfort an operator.

[0070] FIG. 10 shows a thermoelectric heating and cooling aspect generally denoted by numeral 120 including a thermoelectric assembly 122. Still using a blower 124, electronic controller 126 determines the amount of air through air distribution tube 128. Preferably, the seat pad 120 is covered by a 3D mesh material 132 so that heated or cooled air comes upward through air groove 134 by one-way valve 130.

[0071] FIG. 11 includes a detailed illustration of a thermoelectric device generally denoted by numeral 140 emanating in duct enclosure 142 that exits air through one-way valve 156. Air distribution tube 144 urges air into thermoelectric device 146.

[0072] In yet another aspect of the present invention, a self actuating valve material has been found to be useful. In particular, Nitinol’ exhibits super-elastic and shape-memory properties. The most common version of Nitinol* alloy is comprised of approximately equal compositions of nickel and titanium, commonly 56% nickel and 44% titanium by weight. Thermoelectric device 146 includes heat sink 148 and preferably also includes an air flap 150 made of Nitinol*. Air diverter vanes 152 direct the air flow from air distribution tube 144 and disburse the air flow so as to provide a more equally distributed air flow through the heat sinks.

[0073] The air diverter vanes are stationary and are not controlled by the controller. They divert the concentrated air flow from the tube to a more equally distributed air flow over the heat sinks. The occupant conditioned air, either warm or cool air, is exited through one-way valve 156 to the air groove and then through the 3D mesh. Non-occupant air passing through the lower heat sink is exhausted to the ambient environment via exhaust duct 154.

[0074] FIG. 12 is another perspective view of thermoelectric aspect 140 which includes blower 160 for urging air through the air distribution tube 162, feeding into air diverter vane 152 and Nitinol* air flap 150. As air passes through the air distribution tube it flows past thermoelectricassembly 146 to either heat or cool the air passing therethrough. An exhaust air duct 154 removes the air used as a heat source or heat dump from the thermoelectric device that passes through the lower heat sink which allows conditioned air to exit through the upper heat sink and then the one-way valve 156 into further components of the seat pad.

[0075] FIG. 13 is a thermoelectric device assembly with a Nitinol’ flap generally denoted by numeral 140 contained within a duct enclosure 142. Upper and lower heat sinks 148 condition air received through air diverter vanes 152 and thermally conductive thermoelectric module extender 146.

[0076] During heating mode, with the airflow not energized as directed by the controller, the thermally conductive thermoelectric module extender, preferably made of copper or copper alloy, heats the Nitinol* flap and causes it to deflect and block air flow to the cold side heat sink. After given the proper time for flap heating, the blower is energized. The lower volume air flow used in the heating mode from the blower passes through the hot side heat sink and is warmed.

[0077] It should be noted that the thermoelectric system can also be used without the Nitinol’ flaps. Without the Nitinol’ flap, the system is not optimized at heating. When it gets quite cold out, the air flowing over the cold side heat sink can take heat from the hot side of the thermoelectric module and heat sink. The Nitinol’ flap closes off much of the flow of the cold air during the occupant heating mode and allows more heat to reach the seat occupant. The Nitinol’ flap reduces air flow to the heat sinks by reducing blower output. This does two things, i.e. it reduces the amount of cold air flowing over the cold side heat sink, reducing the amount of heat taken from the hot side thermoelectric device and heat sink. Thereby, this, increases the residence time on the heat side, allowing the air to come to a higher temperature, giving the seat occupant a warmer feeling and reducing body moisture evaporation, which can also cause cooling.

[0078] With combined reference to FIG.'s 14A and 14B there is shown a Nitinol’ air-flap valve denoted by numeral 160 showing a two-way Nitinol’ valve in a relaxed or cooled position showing insulating layer 164 in a flat configuration. In order to effect a heated position, two-way Nitinol’ valve 162 is shown in FIG. 14B in a curved or heated position. Insulating layer 164 is shown in a downward facing trajectory for a heated application, while FIG. 14A shows the Nitinol’ air-flap valve 160 in a relaxed position for a cooling state.

[0079] Furthermore, the present invention may provide an improvement of the heating effect using controlled air flow with a self-actuating air valve described below. Utility is found for this heating and cooling thermoelectric device based system only, and would generally not find utility when used in the ventilated and / or resistance heated version. Under normal operation of the thermoelectric module with hot side and cold side heat sinks, the air flow over the heat sinks are generally equal, though they can vary somewhat depending on the desired cooling or heating effect. Air duct design or air diversion also can channel air more to one heat sink or the other. Cold side heat sink and hot side heat sink can change to hot side heat sink and cold side heat sink when the polarity of the DC electrical current going to the thermoelectric device is reversed. The cold side becomes hot and the hot side becomes cold. However, when cooling a seat occupant, removing the heat that is pumped from the cold side to the hot side plus the resistance heating (l2R) that naturally occurs, allows more air to pass over the hot side heat sink which increases the heat transfer of the hot side heat sink, reducing its temperature and allowing more heat to be pumped by the cold side and providing cooler air to the seat occupant.

[0080] On the other hand, in the seat occupant heating mode, running the thermoelectric and heat sink system in a balanced air flow condition works well in temperatures to approximately 32°F (0°C). To improve the air heating ability of the thermoelectric system, it is advantageous to reduce the volume of air flowing over the cold side heat sink. This allows for thesystem to rely more on the resistance heating of the thermoelectric device and less on pumping heat from the cold side to the hot side. A thermoelectric device begins to lose heating effectiveness when the ambient air flowing through the cold side sink is too cold. In yet another aspect of the invention is to reduce airflow across both heat sinks, whereby the air flow arrangement normally has somewhat equal flow across both heat sinks. This allows the system to gain a higher temperature and provide warmer air to the seat occupant, especially in cold ambient conditions. At least one electronic control system senses the cold temperature and operates the air blower in a lower flow condition. The control system can also be set to operate the blower in a lower flow condition whenever heating is desired. For clarity, the flow rate during the heating mode would be lower than the flow rate in cooling mode, especially across the hot side heat sink. FIG. 15 is a depiction of a shape memory material to divert air preferentially over one heat sink or the other heat sink. This is especially helpful in the event of the seat occupant heating mode in a cold ambient temperature environment, resulting in a reduction of the airflow over the cold side heat sink. Consequently, it is preferable to use a two-way Nitinol* flap that automatically deforms to a predetermined bent shape toward shutting off air to the cold side heat sink. When this shape memory material is used in either a non-heating or a cooling mode, the flap relaxes back to its initial position.

[0081] When the heating mode is energized, heat immediately increases on the hot side of the thermoelectric device. The blower is intentionally not activated for a short period of time, allowing the entire thermoelectric assembly to heat. This heating heats the two-way Nitinol* flap. When the flap heats, it deforms to a pre-set shape. In this case, the shape acts as a damper flap that closes off or partially closes off the air flow to the cold side heat sink. The blower then energizes and heated air is directed through the ducts to the seat surface, heating the seat occupant. In this aspect, a two-way Nitinol" flap in the relaxed or cool position and the activated or warm / hot position. Preferably, a thin insulation layer isincluded. This insulation layer helps keep the Nitinol ’ material warm when the incoming air is cold. This insulation layer can be of a thin material such as polyethylene foam, polyurethane foam, polyamide foam, EPDM foam, insulating fabric, insulating scrim or any number of materials that are thin, flexible and are of low thermal conductivity.

[0082] In this novel aspect, a Nitinol’ material is in combination with a thin spring steel layer acting as an airstream director. Further shown is a highly conductive substrate that is an extension of the thermoelectric device substrate. This extension allows heat, when the thermoelectric device is being used as a heating device to heat the Nitinol’ flap, which causes the bending of the Nitinol’ into the flap closing position.

[0083] When not heated, the spring steel layer helps to return the Nitinol’ flap into its open position.

[0084] A Nitinol’ flap goes to a preset shape when heated that could also be used when bonded to a thin, spring metal material that would follow the Nitinol’ deformation during heating mode and upon a non-heating or cooling mode, would pull itself and the Nitinol’ to a relaxed position. This occurs when air flow is approximately equal over both heat sinks.

[0085] The spring metal can be steel, beryllium copper, copper with roll- bonded spring steel, graphene sheets, high conductivity graphite sheets with bonded spring steel, or any suitable material or combinations thereof.

[0086] Suitable materials will have an ability to spring back to a relaxed position with a high thermal conductivity. Having a high thermal conductivity allows for heat from the thermoelectric device to be transmitted to a greater area of the Nitinor faster so as to have the best bending effect when heated.

[0087] The Nitinol’ flap damper preferably also has a thin insulative layer that aids in reducing the cool air passing over the Nitinor flap damper. This keeps the Nitinol" flap damper warmer and more fully deployed to block the incoming cold air from passing through the cold side heat sink.Thermoelectric device power wires 168 are in electrical communication with thermoelectric device 166. Emanating from the high thermal conductivity material 174, preferably copper or other suitable material, is a sheet of Nitinol* 162. Underneath a layer of spring steel 170 is the sheet of Nitinol’ 162. On top of the layer of spring steel 170 is a layer of thermal insulation material 164.

[0088] At least one one-way valve in the air exits directs the heated or cooled airstream to a desired location by a blower including an intake high flow rate, high pressure blower motor. The weather resistant covers over the air ducts prevent water damage.

[0089] The comfort temperature regulating component system is preferably covered by weather resistant covers of hydrophobic, water resistant air flow mesh, especially where the covers are over the air intake. Similar to other aspects described above, there is preferably a waterproof film over the foam bun that keeps water out of the foam. The 3D mesh is porous to water as well as the desired airflow.

[0090] The comfort temperature regulating component system may further comprise a heating system including a low-cost resistance heater placed in the airstream within the air flow distribution ducts that are in communication with the blower or an inline thermoelectric device downstream from the blower motor, wherein heated and cooled air passes over, thereby heating and cooling the airstream.

[0091] Further aspects include a desiccant container added to the air flow distribution ducts to dry the airstream passing there through. Another possible addition may be a weather resistant splash guard to allow for airflow to the blower intake while deflecting splash. Also, some applications find utility in having a valve mechanism that blocks ingress of liquids by the floating of a low density member into a sealing position of the blower intake.

[0092] FIG. 16 illustrates yet another aspect of the invention including a spiral rolled positive temperature coefficient combined heat generator and heat exchanger to provide the heating as an alternative to the heat rod and heat exchanger assembly. A positive temperature coefficient or PTC heater film material is rolled up in a spiral so as to allow air to flow between and through the PTC rolled film material. When electrical energy is provided to the positive temperature coefficient heater, its resistance causes heat to be generated. When air passes through the openings between the rolled layers of positive temperature coefficient heater film, air is heated and distributed to the seat occupant. Positive temperature coefficient material has the property to heat like a conventional resistance type heater, except that when the positive temperature coefficient heater reaches a certain temperature, the resistance of the PTC material printed on the plastic or other type of electrically insulating film, rises rapidly and greatly reduces current flow through the heater.

[0093] This feature can be used for temperature control and / or over temperature protection of the system. Positive temperature coefficient heating devices and the films may be used both as a high density heat sink and a heat source. They can be used together in a forced convection system where the heater and circular heat sink are together.

[0094] Because present day positive temperature coefficient heaters have a fairly low wattage density, another option is to use a resistance heating film that is printed on carbon or any other suitable material, as electrical tracers. Because they are printed on thin, high temperature resistant plastic film, they too can be rolled into a spiral. FIG. 16 shows another aspect of the heater in the present invention as a spiral heater option 180. Such a spiral heater 180 is an outer heater shell 182 and containing a resistance heater film 184, preferably made of positive temperature coefficient or other suitable resistance heater film. Positive temperature coefficient material can be formulated to reach a certain temperature and then go into high electrical resistance, limiting the temperature. By theirnature, they are temperature self-limiting which is a good safety feature. Air from the blower passes through the heater and is unheated if the heater is not energized. When the heater is energized, the heater heats the air.

[0095] FIG. 17A shows the top perspective view of the internal works of a simplified air intake arrangement and heat transfer strip generally denoted by numeral 200. Air intake 202 provides ingress for air to supply blower 204 to channel air into at least one air distribution tube 206. In the back of the seat 200 heat transfer strip 208 works in coordination with controller switch 210. In phantom, an electrical connection pocket allows space for electrical connections between the electrical and electronic components. Seat pad 216 covers all these components, and is preferably a perforated vinyl seat covering over seat pad 216.

[0096] Looking to FIG. 17B, another aspect if the present invention includes a view of seat pad 216 showing the relative placement of heat transfer strip 208. It should be noted that heat transfer strip 208 may extend throughout the entire width of seat pad backing 218, or any other suitable length of heat transfer strip to be effective in the heat transfer strip acts to cool the blower electronics and bearings. The heat transfer strip is placed on the back surface exposed to the ambient environment. The placement can be elsewhere as well, such as the seat side that is not in contact with the occupant. During ventilation of the seat, as would occur when it is hot outside, adding more heat to the seat occupant would not be desirable. Again, blower 204 feeds air through air distribution tube 206 exiting the one way valve 214. Electronic controller 210 is in electronic communication by way of the electrical connection area 212 to control the blower 204. During operation of the blower 204, the heat transfer strip 208 conducts heat from the blower 204 to the skin or covering of the seat pad. Suitable materials to be used for the heat transfer strip may include thin strips, a flat braided copper cable, thermally conductive graphene strips, pyrolytic graphite strips, aluminum, highly thermally conductive graphitestrips or any other suitable material that is highly thermally conductive and also flexible and thin. Heat transfer strip 208 may be bonded to a blower heat sink, preferably aluminum or copper. The blower heat sink may be part of the blower housing. A thermally conductive adhesive is preferably utilized to bond the heat transfer strip to the inner surface of the seat pad skin or covering. Depending upon the thermally conductive adhesive material being used, the adhesive may be sewn onto the seat pad skin covering or on both surfaces. In yet a second aspect, the heat sink for blower electronics preferable surrounds air intake 202 to maximize thermal conductivity for effective reduction of temperature of the blower electronics.

[0097] In addition to the applications described above other possible uses may include motorcycle & motor scooter seating, off-road vehicles, all terrain vehicles, military vehicle seating, wheelchairs, therapeutic seating for maintaining, reducing, and or increasing body temperature, automotive & truck seating, stadium seating, golf carts and neighborhood electric vehicle seating, office seating, and any other suitable application.

[0098] Therefore, a comfort temperature regulating component system Is disclosed including a weather resistant ventilated assembly comprising a ventilated component system cover to protect the inner workings from outside elements under the component system cover. At least one air flow distribution duct has air ducts and air exits to direct either a vented, heated or cooled airstream generated from the comfort temperature regulating component system to comfort anyone in contact with the cover.

[0099] In order to achieve weather resistance, there is preferably at least one valve in the air exits directing the airstream to a desired location contacting a user. A blower includes an airflow intake with a high flow rate blower motor to move the airstream through the air ducts; and then through weather resistant covers over the air ducts. The weather resistant covers preferably include hydrophobic mesh covers over the air exits, andare especially useful if they include 3D mesh materials that are commercially available.[O1OO] In order to produce the heated mode, the comfort temperature regulating component system has a heating system including a resistance heater that may be placed in the airstream within the air flow distribution ducts that are in communication with the blower. Alternatively, the comfort temperature regulating component system may further comprise an inline thermoelectric device downstream from the blower motor, wherein heated and cooled air passes over the inline thermoelectric device, thereby heating and cooling the airstream.

[0101] At least one valve in the air exit inhibiting the ingress of water and any other unwanted substances from penetrating through the ventilated cover. This is especially useful in seats for outdoor vehicles of any type.

[0102] The comfort temperature regulating component system may be optimized when the at least one valve in the air exits directs the heated or cooled airstream to a desired location through at least one self-actuating two-way valve.

[0103] In one preferred comfort temperature regulating component system, the system includes attachment straps for an attachable seating component acting as an accessory to a permanent installation. This way, a permanent installation can be updated with the addition of the comfort device when the permanent installation is utilized as a support for such an accessory as disclosed in the present invention, thereby retrofitting an existing seat. In addition, the present comfort temperature regulating component system may be used as a permanently installed installation.

[0104] In either aspect, the one-way valve prevents ingress of water or other outer elements In order to protect any underlying electronic or corrosive prone components.

[0105] In order to control the temperature of the comfort temperature regulating component system, the air diverter includes a controller. It isespecially useful when that controller is in communication with the self actuating Nitinor air damper.

[0106] The comfort temperature regulating component system may also include an insulative layer in conjunction with the two-way valve controlling an air damper of the comfort temperature regulating component system.

[0107] This insulation layer can be of any suitable thin material such as polyethylene foam, polyurethane foam, polyamide foam, EPDM foam, insulating fabric, insulating scrim, combinations thereof or any number of materials that are thin, flexible and are made of a low thermal conductivity material.

[0108] The comfort temperature regulating component system may further comprise a thermally conductive thermoelectric module extender. The thermoelectric module extender is preferably made from a material selected from the group consisting of copper, copper alloy, graphene, other suitably high thermally conductive materials, and combinations thereof.

[0109] In addition, to add extra comfort to the comfort temperature regulating component system of the present invention, an additional yet separate resistance heater transfer strip can be built into and included in thermal and electronic communication with the rest of the system. The aforementioned controller is included to regulate the temperature of this system.
