Description
- This application is claims benefit under 35 U.S.C § 119(e) to U.S. Provisional Patent Application No. 60/681,359, filed on May 16, 2005, the entirety of which is hereby incorporated by reference herein and made a part of the present disclosure.
- 1. Field of the Invention
- At least one of the inventions disclosed herein relates generally to climate controlled seat technology. Particularly, at least one of the inventions relates to providing and controlling ventilated air provided to the headrest of a set.
- 2. Description of the Related Art
- Temperature modified air for environmental control of living or working space is typically provided to relatively extensive areas, such as entire buildings, selected offices, or suites of rooms within a building. In the case of vehicles, such as automobiles, the entire vehicle is typically cooled or heated as a unit. There are many situations, however, in which more selective or restrictive air temperature modification is desirable. For example, it is often desirable to provide an individualized climate control for an occupant seat so that substantially instantaneous heating or cooling can be achieved. For example, an automotive vehicle exposed to the summer weather, where the vehicle has been parked in an unshaded area for a long period of time, can cause the vehicle seat to be very hot and uncomfortable for the occupant for some time after entering and using the vehicle, even with normal air conditioning. Furthermore, even with normal air-conditioning, on a hot day, the seat occupant's back and other pressure points may remain sweaty while seated. In the winter time, it is highly desirable to have the ability to quickly warm the seat of the occupant to facilitate the occupant's comfort, especially where the normal vehicle heater is unlikely to warm the vehicle's interior as quickly.
- For such reasons, there have long been various types of individualized climate control systems for vehicle seats. Such climate control systems typically include a distribution system comprising a combination of channels and passages formed in the cushion of the seat. Climate conditioned air is supplied to these channels and passages by a climate control device. The climate conditioned air flows through the channels and passages to cool or heat the space adjacent the surface of the vehicle seat.
- There are, however, problems that have been experienced with existing climate control systems for seats. Most seat assemblies, even those with climate control of the seat, do not address providing climate controlled air to the headrest. Moreover, some seat assemblies have a headrest supported above the seat back, typically by adjustable posts. Thus, these headrests, usually including a cushion, are not only physically distinct from the cushion of the seat, but are also adjustable relative to the seat. Thus, any climate controlled air provided to the headrest must account for flexibility in connection of the air-providing apparatus.
- Thus there is a need for an improved climate control apparatus for a climate control system for seats with headrests.
- Accordingly, one aspect of the present invention comprises a climate controlled seat assembly that includes a seat having a seat cushion, a backrest having a backrest cushion, and a headrest having a headrest cushion. The headrest is moveably mounted to the backrest. The headrest cushion includes at least one fluid passageway extending at least partially therethrough. A thermoelectric device is in fluid communication with the at least one fluid passageway. A fluid transfer device that is in fluid communication with the at least one fluid passageway is coupled to the headrest such that the thermal module moves with the headrest as it is moved with respect to the backrest.
- Another aspect of the present invention comprises a climate controlled seat assembly that includes a seat having a seat cushion, a backrest having a backrest cushion with at least one first fluid passageway extending at least partially therethrough and a headrest having a headrest cushion. The headrest is positioned generally above the backrest. The headrest includes a headrest cushion with at least one fluid passageway extending at least partially therethrough. A backrest thermal module includes a thermal electric device and a fluid transfer device. The backrest thermal module is in fluid communication with the at least one fluid passageway in the backrest cushion. A headrest thermal module comprises a fluid transfer device. The thermal module is in fluid communication with the at least one fluid passageway in the headrest cushion. The backrest thermal module and the headrest thermal module are supported within the backrest.
- Another aspect of the present invention is a climate controlled seat assembly that includes a seat having a seat cushion, a backrest having a backrest cushion and a headrest having a headrest cushion. The headrest cushion comprising at least one fluid passageway extending at least partially therethrough. A thermal module is in fluid communication with the at least one fluid passageway. The thermal module is configured to cooled fluid to the at least one fluid passageway.

FIG. 1 illustrates one embodiment of a ventilatedseat assembly 30. In the illustrated embodiment, theseat assembly 30 can include aseat 32 and abackrest 34. When the occupant sits in theseat assembly 30, the occupant's back contacts afront surface 48 of thebackrest portion 34 and the occupant's seat and legs contact atop surface 50 of theseat portion 32. Thesurfaces seat assembly 30 can be configured and sized to accommodate occupants of various size and weight. - In the illustrated embodiment, the
seat assembly 30 is similar to a standard automotive seat. However, it should be appreciated that certain features and aspects of theseat assembly 30 described herein may also be used in a variety of other applications and environments. For example, certain features and aspects of theseat assembly 30 may be adapted for use in other vehicles, such as, for example, an airplane, a boat, or the like. Further, certain features and aspects of theseat assembly 30 may also be adapted for use in stationary environments, such as, for example, a chair, a sofa, a theater seat, a mattress, and an office seat that is used in a place of business and/or residence. Certain features and aspects can also be adapted to wheelchairs and assemblies that do not support a user in a seated position (e.g., beds). - With continued reference to
FIG. 1 , thebackrest 34 has arear side 56, abottom side 60 and afront side 64. Although not illustrated, thebackrest 34 can include a pair of sides for providing lateral support to the occupant of theseat assembly 30. Theseat portion 32 can include arear side 66, a top side 68 and abottom side 70. Theseat portion 32 can also include a pair of sides (not illustrated), which can extend from therear side 66 and thefront side 64 for providing lateral support to the occupant of theseat assembly 30. In one embodiment, theseat assembly 30 is secured to a vehicle by attaching thebottom side 70 of theseat portion 32 to the floor of a vehicle. - As shown, the
seat assembly 30 can also include aheadrest 202. Theheadrest 202 can preferably be supported by one ormore support members 204 above thebackrest portion 34. In a preferred embodiment, at least the height of theheadrest 202 with respect to thebackrest 34 can be adjusted. In one embodiment, the height can be adjusted by changing the length of thesupport members 204. Of course, those of skill in the art will recognize that any of a variety of adjusting mechanisms can be used to adjust the position of theheadrest 202 andbackrest 34. In some embodiments, such mechanisms can also adjust the angle of theheadrest 202 with respect to thebackrest 34. - The
backrest 34,seat portion 32 andheadrest 202 are generally formed by acushion 72, which is covered with an appropriate covering material 74 (e.g., upholstery). Thecushion 72 is typically supported on a metallic frame (not shown). In some embodiments, springs may be positioned between the frame and thecushion 72. The frame provides theseat assembly 30 with structural support while thecushion 72 provides a soft seating surface. The coveringmaterial 74 provides an aesthetic appearance and soft feel to the surface of theseat assembly 30. Thecushion 72 can be a typical automotive seat cushion foam or other types of materials with suitable characteristics for providing support to an occupant. Such materials include, but are not limited to, closed or open-celled foam. - With continued reference to
FIG. 1 , thebackrest 34,seat 32 and theheadrest 202 can includefluid distribution systems front surfaces backrest 34,seat 32 and theheadrest 202. In general, thefluid distribution systems inlet passages seat cushion 72. Thefluid distribution systems channels 80A, 80B, 80C, which extend from theinlet passages top surfaces seat assembly 34. - As mentioned above, the
cushion 72 may be formed from a typical automotive cushion material, such as, for example, an open or closed cell foam. In one embodiment, thecushion 72 is made of foam that is pre-molded to form thepassages channels 80A, 80B, 80C. In another embodiment, thepassages channels 80A, 80B, 80C can be formed by cutting foam out of theseat cushion 72. - As will be described in more detail below, the
channels 80A, 80B, 80C can be covered by a scrim to definedistribution passages seat assembly 30. The scrim can includes one or more openings for delivering air to and/or from thedistribution passages cushion 72. In one embodiment, the scrim can be attached to thecushion 72 in a manner that limits leakage between the scrim and cushion 72 thereby directing the flow of air through the openings. In one embodiment, an adhesive is used to attach the scrimA to thecushion 72. In other embodiments, a heat stake or fasteners can be used. - A distribution layer can be disposed between the scrim and the seat covering. The distribution layer can spread the air flowing through the openings along the lower surface of the covering. To permit airflow, the covering may be formed from an air-permeable material. For example, in one embodiment, the covering comprises an air-permeable fabric made of natural and/or synthetic fibers. In another embodiment, the covering is formed from a leather, or leather-like material that is provided with small openings or apertures.
- The
fluid modules distribution system 76C. In other embodiments, themodules passages - With continued reference to
FIG. 1 , in a preferred embodiment, thefluid modules thermoelectric device 94 B 94C for conditioning (e.g., selectively healing or cooling) the fluid flowing through thedevice thermoelectric device fluid modules main heat exchanger modules distribution systems distribution system conduits modules waste heat exchanger thermoelectric device main heat exchanger waste heat exchanger distribution system pumping device fluid module waste heat exchangers pumping device - Each
fluid module control unit 110. Thecontrol unit 110 can be configured to control anyfluid module control unit 110 senses at least one state of thefluid modules fluid modules - The
control module 110 optionally can also be configured to receive a signal from a vehicle control device that can indicate whether the vehicle's ignition has been turned on. In this manner, theseat control module 110 can be configured to allow operation of the system only if the vehicle's engine is running. In one embodiment, thecontrol unit 110 received a control signal from a user operated control device and/or another component of the vehicle operating system. Thecontrol unit 110 uses the control signal to drive and control thefluid modules fluid modules - Various components can be described as being “operatively connected” to the
control unit 110. It should be appreciated that this is a broad term that includes physical connections (e.g., electrical wires or hard wire circuits) and non-physical connections (e.g., radio or infrared signals). It should also be appreciated that “operatively connected” includes direct connections and indirect connections (e.g., through additional intermediate device(s)). - It should be appreciated that the
fluid modules distribution systems - The
pumping device fluid module headrest 202. As such, it can be preferred that thefluid module 92C and pumping device 102 are compact. Therefore, in a preferred embodiment, the pumping device can comprise an electrical radial fan. In other embodiments, the pumping device can comprise other types of electrical fans or blowers, such as, for example, an axial blower. - With continued reference to
FIG. 1 , in the illustrated embodiment, the seat assembly includes theheadrest 202 with thefluid module 92C associated with theheadrest 202. In one embodiment, theheadrest fluid module 92C can be coupled to theheadrest 202 such that it moves with theheadrest 202 as it is adjusted. For example, in certain embodiments, theheadrest 202 is configured to be moved at least vertically with respect to thebackrest 34. In such an embodiment, theheadrest fluid module 92C can be coupled to therear side 57 of theheadrest 202. In another embodiment, theheadrest fluid module 92C can be positioned at least partially within theheadrest 202. -
FIG. 2 illustrates a modified illustrated embodiment of aseat assembly 300. This embodiment also includes aheadrest 202,seat 32 andbackrest 34 as described above. Theheadrest 202 can also include adistribution system 76C as described above. In this embodiment, aconnection passage 302 can be provided to place thedistribution system 76C for the headrest in communication with thefluid module 92A for thebackrest 34. In the illustrated embodiment, theconnection passage 302 can extend at least partially through thebackrest 34 and through thesupport member 204. In a modified embodiment, the connection passage can extend further (e.g., into the seat 32) such that it is connected to thefluid module 92B for theseat 32 or another portion of theseat assembly 300. - With continued reference to
FIG. 2 , the dashed lines indicated by thereference number 320 illustrate another embodiment in which aconnection passage 320 can connect thesupply passage 98A to thedistribution system 76C. Theconnection passage 320 can extend outside and/or along thebackrest 34. - Thus, at least one embodiment can have a ventilated
backrest 202 comprising adistribution system 76C, wherein fluid is supplied to theheadrest 202 from fluid communication with afluid conduit 78A disposed within thebackrest 34. In the illustrated embodiment, analternative passage 302 for fluid communication is shown. As can be seen, fluid can be supplied to theheadrest 202 by thefluid module 92A associated with thebackrest 34, which also supplies fluid to thefluid distribution system 76A for the backrest. -
FIG. 3 illustrates yet another embodiment of ventilatedseat assembly 400. In this embodiment, aconnection passage 402 can extend through, near or along thesupport member 204 and through thebackrest 34. Thefluid module 92C for theheadrest 202 can be associated with the backrest 34 (e.g., coupled or supported on the backrest or positioned partially therein). Although thepassage 402 is illustrated as extending through thebackrest 34, it should be appreciated that all or a portion of thepassage 402 can extend outside thebackrest 34. Additionally, at least a portion of thefluid passage 402 can extend through thebackrest 34, while not extending near or along thesupport member 204. -
FIG. 4 illustrates yet another embodiment of ventilatedseat assembly 500. In this embodiment, asingle fluid module 92A can remove or supply conditioned (e.g., cooled or cooled/heated) air to theheadrest 202, thebackrest 34 and theseat 32.Connection passages 502A-C can be provided for connecting the fluid module 92 to thedistribution passages backrest 34, theseat 32 and theheadrest 202. The passages can be formed entirely within the seat assembly, partially within the seat assembly or entirely outside the seat assembly or any combination thereof. In addition, thedistribution passages distribution passages - Thus, more than one
fluid distribution system single fluid module 92A can supply heated, cooled, or unconditioned air to, or withdraw air from, all of thefluid distribution systems - As is apparent from the description above, the above described embodiments can be configured to provided conditioned, and in particular, cooled air to the
headrest 202 of the seat assembly. This is particularly advantageous because the cooling sensation can be more effectively perceived by the user when it is directed towards the neck and head area. For example, because of the large arteries in the back of the head, the cooling effect is often felt over the entire body of the user. Thus, by directing cool air in particular toward the user's head and neck, a more effective cooling sensation can be felt by the user as compared to the same level of cooling in the seat and backrest. - At least a part of the connecting members between a fluid module 92 and a fluid distribution system 82 can comprise a flexible or articulable conduit, as described below. In particular, in the embodiments illustrated in
FIGS. 2, 3 and 4, at least a portion of the passages supplying or removing air from theheadrest 202 can be flexible to accommodate the adjustment of the position of theheadrest 202 with respect to thebackrest 34. For example, it can be advantageous to make the portion of the passage extending between theheadrest 202 and thebackrest 34 flexible (e.g., a bellow as described in U.S. patent application Ser. No. 10/973,947, filed Oct. 25, 2004, which is hereby expressly incorporated by reference herein). It should also be appreciated that in the embodiments in which the supply passage extends through thesupport member 204 it can be advantages to use a flexible conduit. Such a flexible conduit can also be used in embodiments in which the supply passage extends outside (e.g., along) thesupport member 204. -
FIG. 5 illustrates one embodiment of such a flexible conduit. Theconduit 1096 can include abody 1098 having a first,inlet end 1100 and a second,outlet end 1102. Theinlet end 1100 can form a first orinlet port 1104 and theoutlet end 1102 can form a second oroutlet port 1106. A fluid passage (not shown) can be formed by an inner surface of thebody 1098. The fluid passage 1108 can extend from an inlet opening formed by theinlet port 1104 and an outlet opening formed by theoutlet port 1106. - To facilitate such movement, at least a portion of the
body 1098 can be flexible and/or capable of articulated movement. In addition, it is also advantageous that the length of thebody 1098 can be lengthened or shortened. Accordingly, in the illustrated embodiment, thebody 1098 can be formed, at least in part, from a flexible material such as, for example, rubber, other elastomers, flexible thermoplastics, and the like. During movement, it can be advantageous that the cross-sectional area of the passage 1108 not be significantly reduced (e.g., by crimping or buckling). Accordingly, in the illustrated embodiment, thebody 1098 can have a bellow-type configuration comprising a plurality offolds 1116. In this manner, as theconduit 1096 bends the inner radius can shorten while the outer radius can lengthen to substantially preserve the cross-sectional area of the fluid passage 1108. In addition, the length of theconduit 1096 can be increased or decreased as the bellows expand or contract without significantly compromising the fluid passage 1108. - Of course, those of skill in the art will recognize other arrangements for facilitating one or more of the degrees of movement described above. Such arrangements include, but are not limited, to various arrangements of telescoping members, braided conduits, flexible joints and the like.
- With continued reference to
FIGS. 5-7 , the inlet and outlet ends 1100, 1102 of theconduit 1096 can preferably be formed of a harder material as compared to the flexible portions therebetween. For example, in one embodiment, the inlet and outlet ends 1100, 1102 can be formed from a substantially rigid plastic while the portions of theconduit 1096 extending between the ends 100, 102 can be formed from a flexible material (e.g., rubber). The inlet and outlet ends 1100, 1102 can be formed from separate components that are attached to the remaining portions using adhesives, heat stakes, fasteners, etc. or by over-molding such portions. -
FIG. 6 is a cross-sectional view of an embodiment of theheadrest 202, taken along line 6-6 inFIG. 1 .FIGS. 7, 8 , and 9 are cross-sectional views of other embodiments ofheadrests 202, taken along a similar line for each embodiment. As will be explained below, in these embodiments, theheadrest 202 includes one or morethermal elements 160, which can be used to thermally condition (e.g., heat) air flowing through thedistribution system 76C. For the sake of brevity, thethermal elements 160 and other aspects of thedistribution system 76C will be described with respect to theheadrest 202. However, it will be appreciated that these features and aspects can be extended to thedistribution systems backrest 34 andseat 32. - As mentioned above, the
headrest portion 202 can generally be formed by acushion 72, which can be covered with an appropriate covering material 74 (e.g., upholstery, leather or vinyl). Thecushion 72 can be usually supported on a metallic or plastic frame (not shown). In some embodiments, springs can be positioned between the frame and thecushion 72. The frame can provide theheadrest 202 with structural support while thecushion 72 provides a soft surface for resting or leaning the occupant's head. The coveringmaterial 74 provides an aesthetic appearance and soft feel to the surface of theheadrest 202. - The
distribution system 76C can be formed with or without aninsert 150. In some embodiments, theinsert 150 in the shape of formed channels can be disposed on the surface of thecushion 72 of theheadrest 202, but beneath the coveringmaterial 74. Thus, conditioned air can be directed to the surface of theheadrest 202 through the channels of theinsert 150 as an alternative to the embodiments described below. In one embodiment, theinsert 150 is made of a material that is more impermeable to air as compared to thecushion 72. For example, in one embodiment, theinsert 150 comprises closed cell foam or a plastic while thecushion 72 comprises an open cell foam. Theinsert 150 can also include aflanged portion 158, which extends generally parallel to a top surface of thecushion 72. - With continued reference to
FIG. 6 , a cover orscrim 81 can be positioned generally over theinsert 150 to definedistribution passages 82C for transporting air through theheadrest 202. Thescrim 81 can include one ormore openings 84 for transporting air to and/or from thedistribution passages 82C and preferably can provide structural support to prevent or reduce theseat cover 74 from depressing into thepassages 82C. Thescrim 81 preferably can include one or morethermal elements 160, which can preferably be positioned within thescrim 81 generally adjacent the one ormore openings 84 and are configured to effect a temperature change in the space adjacent theheadrest 202. As will be explained in more detail below, in the illustrated embodiment, thethermal elements 160 are used to heat the air transported through the seat assembly and/or heat the portions of the seat assembly adjacent thethermal elements 160. In a modified embodiment, thethermal elements 160 can comprise substantially continuous pad and/or a pad with a plurality of openings that generally replaces or lies over thescrim 81. - The
thermal elements 160 may comprise any of variety of devices for causing a temperature change, such as, for example, resistive heaters (e.g., resistive wires, carbon fiber based heating elements, and carbon impregnated sheets), chemical-reaction heaters, heat exchanges and/or Peltier thermoelectric devices. Thethermal elements 160 may be used in combination with fabrics, foams etc. to form thescrim 81. In other embodiments, thethermal elements 160 can be coupled to or positioned generally near thescrim 81. In the illustrated embodiment, thescrim 81 can be attached to theflange 158 in a manner that limits leakage between thescrim 81 and theinsert 150, thereby directing the flow of air through theopenings 84. In some embodiments, an adhesive can be used to attach thescrim 81 to theinsert 150. In other embodiments, a heat stake or fasteners can be used. - With continued reference to
FIG. 6 , anoptional distribution layer 86 can be disposed between thescrim 81 and the seat covering 74. Thedistribution layer 86 can spread the air flowing through theopenings 84 along the lower surface of thecovering 74. To permit airflow between thedistribution layer 86 and the spaces proximal to the front surface of theheadrest 202, the covering 74 can be formed from an air-permeable material. For example, in at least one embodiment, the covering 74 can comprise an air-permeable fabric made of natural and/or synthetic fibers. In other embodiments, the covering 74 is formed from a leather, or leather-like material that can be provided with small openings or apertures. In other embodiments, thedistribution layer 86 can be omitted or combined with the seat covering 74 and/or thescrim 81. Thescrim 81 can be configured to allow for the passage of air. In the illustrated embodiment, this can be accomplished by providing thescrim 81 with small openings or apertures. In other embodiments, thescrim 81 itself and/or thethermal elements 160 may be generally air-permeable. -
FIG. 7 illustrates a modified embodiment of thedistribution system 76C′ for theheadrest 202. As in the previous embodiment, thedistribution system 76C′ comprises aninlet passage 78C that extends from the rear side of theheadrest 202 to thefront side 206 of theheadrest cushion 72. As with thedistribution system 76C described above, thedistribution system 76C′ also can include at least one, and often, a plurality ofchannels 80C, which extend from theinlet passage 78C. Thesechannels 80C can be configured as described above. - In the
distribution system 76C′, the portion of theheadrest cushion 72 that forms thechannels 80C can preferably be treated and/or covered with a coating, skin or other material configured such that air flowing through thechannels 80C does not significantly seep into theheadrest cushion 72. In other embodiments, theheadrest cushion 72 can be formed from a dense foam, such as one that does not allow for significant seepage of air through the foam. In addition to or in the alternative, thedistribution system 76C′ can include an insert or liner as described above with reference toFIG. 6 . - The
channels 80C are covered by the scrim or cover 81 to definedistribution passages 82C, as described above, for transporting air through theheadrest 202. Thescrim 81 can preferably be configured as described above. Accordingly, thescrim 81 can includethermal elements 160 and one ormore openings 84 for delivering air to and/or from thedistribution passages 82C. As described above, thescrim 81 can preferably be attached to theheadrest cushion 72 in a manner that limits leakage between thescrim 81 andheadrest cushion 72. Adistribution layer 86 can be optionally disposed between thescrim 81 and the seat covering 74. As mentioned above, in some embodiments, thedistribution layer 86 can be omitted or combined with the headrest covering 74 and/or thescrim 81. In addition, as with the headrest covering 74, thescrim 81 itself can be configured such that it can be generally air-permeable and/or provided with small openings or apertures 8B as shown in the illustrated embodiment. - The
thermal elements 160 can be used to change the temperature (e.g., increase) in the space or portions of the headrest adjacent the occupant of the seat assembly 200. Thethermal elements 160 can preferably be used in combination with fluid flow provided through thedistribution system 76C. As explained below, when used in combination with fluid flow, the air can be conditioned or unconditioned before thethermal elements 160 changes its temperature. For example, in some embodiments, air (which can be heated) can be delivered to thedistribution passages 82C through theinlet passages 78C. The air then flows through theopenings 84 and into the distribution layers 86. The air is then directed through the covering 74 to a space adjacent to the front surface of theheadrest 202. In some embodiments, theclimate control system 96C can be used to remove air, which is adjacent to the front surface of theheadrest 202. In such embodiments, the air can be withdrawn through the covering 74 and into the distribution layers 86. The air can be then withdrawn through theopenings 84 into thedistribution passages 82C and through theinlet passage 78C. Thus, the air withdrawn and/or supplied through thedistribution systems 76C can be used to supplement and/or enhance thethermal elements 160. In some embodiments, thethermal elements 160 provide heat to the occupant via conduction through the covering 74 and other layers of material. In such embodiments, the fluid flow can enhance thethermal elements 160 by also transferring the heat generated by thethermal elements 160 to the occupant via convection and/or conduction. - Given the goal of distributing air through the
cushion 72 and along the covering 74, those of skill in the art will recognize that thedistribution systems 76C for theheadrest 202 can be modified in several different manners. For example, the shape and/or number ofchannels 80C and/oropenings 84 can be modified. In other embodiments, thescrim 81 and/ordistribution passages 82C can be combined and/or replaced with other components configured for similar functions. In other embodiments, thedistribution systems backrest 34,seat 32 andheadrest 202 or portions thereof may be combined and/or interchanged with each other. -
FIGS. 8 and 9 illustrate modified embodiments of thedistribution systems 76C. InFIGS. 8 and 9 , elements similar to those shown inFIGS. 6 and 7 are designated with the same reference numbers used inFIGS. 6 and 7 . In addition, only certain components of the climate control system will be described in detail below.

FIG. 7 , in this embodiment, thethermal element 160 for theheadrest 202 can form at least in part a portion of theinsert 150, which can form at least partially thedistribution passage 82C. The air flowing through the distribution passage can be heated by thethermal element 160 and then be delivered to the occupant through theopenings 84. In a modified embodiment, thethermal element 160 can be positioned along the inner or outer surface of theinsert 150. - With respect to
FIG. 9 , thethermal elements 160 can line and/or form part of thechannels 80C in theheadrest cushion 72. Thus, thethermal elements 160 can heat the air flowing through thepassages 82C. In some embodiments, thethermal elements 160 can be positioned within thecushion 72. - Accordingly, with the
thermal elements 160 generally positioned within thecushion 72 between theseat cover 74 and the front side and the rear (or bottom) of the respected seat component (i.e. theheadrest 202,backrest 34, seat 32), thethermal elements 160 can heat the air delivered by the fluid module. It should be appreciated that in some embodiments, one or more thermal elements (not shown) can be provided near or adjacent the front or top surfaces of theheadrest 202,backrest 34,seat 32. In such embodiments, the thermal elements can be provided within thescrim 81 as described above with reference toFIGS. 6 and 7 . With reference back toFIG. 1 , as shown, thebackrest 34,seat 32, andheadrest 202 can each include one or morethermal elements thermal modules thermal modules thermal elements control unit 110 or another separate control unit for controlling their operation. - With continued reference to
