Detailed Description
The following embodiments are described with reference to the accompanying drawings. The relationship and functioning of the various elements of the embodiments are better understood by the following detailed description. However, the embodiments as described below are given by way of example only, and the present invention is not limited to the embodiments shown in the drawings. It should also be understood that the figures are not drawn to scale and that in some instances, details that are not necessary for an understanding of the embodiments have been omitted.
As generally shown in fig. 1, one embodiment of the present invention is directed to a ventilation system 100 for a vehicle seat 102 in a passenger compartment of a vehicle. The vehicle seat 102 includes a seat bottom 104 and a seat back 106 pivotally coupled to one another. In this example, the ventilation system 100 is integrated within a seat bottom 104 of a vehicle seat 102. However, it is contemplated that the ventilation system may be integrated within the seat back 106 or any other portion of the vehicle seat.
Referring to fig. 2A and 2B, the ventilation system 100 includes an air mover or fan 108, an air distribution device 110 fluidly coupled to the fan 108, and an a-surface or cover layer 112 (fig. 1) of the vehicle seat 102 formed of an air permeable material fluidly coupled to the air distribution device 110. The seat bottom 104 includes a seat cushion 114 having an a side 116 (fig. 2A) facing the cover 112 and a B side (fig. 2B) facing away from the cover 112. The seat bottom 104 also includes one or more foam padding elements 120 positioned adjacent the a-side 116 of the seat cushion 114, wherein the air distribution device 110 is positioned adjacent the B-side 118 of the seat cushion 114. However, it is contemplated that the air distribution device may be positioned adjacent to the a-side 116. In this example, the vehicle seat 102 may also include an air permeable heating mat 119 that includes one or more heating elements (not shown) and is positioned between the foam padding element 120 and the cover layer 112. Other examples of vehicle seats may not include a heating pad.
The ventilation system 100 is configured to pull air around a vehicle occupant on the covering 112 such that ambient air within the passenger compartment supplements the air around the vehicle occupant. More specifically, the ventilation system 100 is configured to draw air around a vehicle occupant through the cover layer 112, the heating pad 119, the foam padding element 120, the seat cushion 114, the top layer 128 of the air distribution device 110, the spacer layer 140 of the air distribution device 110, the bottom layer 122 of the air distribution device 110, and the fan 108 in that order.
In another example, the ventilation system 100 may push air toward a vehicle occupant located on the cover layer 112. Specifically, the fan 108 may generate an air flow that is directed through the bottom layer 122 of the air distribution device 110, the spacer layer 140 of the air distribution device 110, the top layer 128 of the air distribution device 110, the seat cushion 114, the foam padding element 120, the heating cushion 119, and the cover layer 112 and toward the vehicle occupant. Another example of a ventilation system 100 may be configured to selectively push air toward and pull air from a vehicle occupant in one or more areas of the seat bottom 104 and/or the seat back 106.
Referring to fig. 3 and 4A, a first embodiment of the air distribution apparatus 110 includes a bottom layer 122 formed of an air-impermeable material having a bottom peripheral edge 126 and defining a single aperture 124 spaced from the bottom peripheral edge 126. The single aperture 124 is in fluid communication with the fan 108, such as through a bellows or foam ring (neither shown).
As best shown in fig. 4A, the air distribution device 110 includes a top layer 128 formed of an air permeable material and having a top peripheral edge 130 sealingly coupled to the bottom peripheral edge 126 of the bottom layer 122 to define an interior chamber 132. Specifically, the air distribution apparatus 110 includes one or more mechanical fasteners 133 that are non-adhesive (no adhesive) for attaching the bottom perimeter edge 126 and the top perimeter edge 130 to each other. Examples of these mechanical fasteners may include stitching (suture) 133 (fig. 4A), staples 135 (fig. 4B), hook and loop fasteners 137 (fig. 4C), other suitable mechanical fasteners, or any combination thereof. Further, in this embodiment, bottom perimeter edge 126 and top perimeter edge 130 are unfolded (unfolded) and extend radially outward. However, it is contemplated that one or both of bottom perimeter edge 126 and top perimeter edge 130 may be folded radially inward (fig. 4D). Non-limiting benefits of the inwardly folded edges may include providing a more compact device and facilitating installation of the air distribution device 110 in a vehicle seat.
Referring to fig. 5A and 5B, the top layer 128 is formed from a sheet of air permeable fabric 151 (fig. 5B) that includes a plurality of fibers 153 spaced apart from one another to define a plurality of channels 155 through the fabric that enable air to flow only through the channels in the fabric 151. The air permeable fabric 151 can be a uniformly woven fabric in which the fibers 153 are woven together to define channels 155 between the fibers 153. In other words, the top layer 128 does not include any holes, openings, or apertures cut, stamped, or otherwise formed in the top layer during a process separate from the process used to form the air permeable fabric. The top layer 128 may have a footprint or surface area configured to direct air toward a portion of the cover layer 112 corresponding in size to the footprint or surface area of the top layer 128. One non-limiting benefit of the top layer 128 not being formed from an air impermeable material having a plurality of holes cut or stamped into the air impermeable material is that the seat manufacturing process is improved by eliminating the need to align the holes of the top layer with corresponding holes of the seat cushion 114.
Referring to fig. 5C, another example of the top layer 228 can be formed from a nonwoven air permeable fabric 251 that includes shorter short fibers (staple fibers) 253a and continuous long fibers 253b that are joined together by chemical, mechanical, thermal, or solvent treatment. One example of a nonwoven fiber is a felt, which is neither woven nor knitted. The nonwoven fibers may include a non-uniform or random arrangement of fibers 253a, 253b, with the fibers 253a, 253b being joined together and spaced apart from one another to define a plurality of channels 255 between the fibers 253a, 253b such that the top layer 228 enables air to flow only through the channels 255 in the fabric 251.
Referring to FIG. 5D, yet another embodiment of the top layer 328 may be formed from a sheet of homogenous material 351 having a porous structure 353 forming a plurality of channels 355 through the top layer 328 that enables air to flow only through the channels 355 in the top layer 328. As one example, the homogeneous material may be formed of an open-cell, porous foam. Other embodiments of suitable air permeable top layers are envisaged.
Referring to fig. 4A and 5A, the air distribution apparatus 110 can further include one or more barriers 134 formed of an air-impermeable material coupled to one or more portions of the top layer 128 for selectively directing air through other portions of the top layer 128. In this example, the top layer 128 can include a central portion 138 disposed radially inward of the top peripheral edge 130, and the barrier 134 can be one or more strips of tape attached to the top layer 128 and extending along or parallel to the top peripheral edge 130 of the top layer 128. In this manner, the barriers 134 may direct air through a central portion 138 of the top layer 128, the central portion 138 being spaced radially inward from the peripheral edge 126 of the top layer 128. Other embodiments of the barrier may be one or more strips, sheets, or films (membranes) of air-impermeable material coupled to any portion of the top layer 128 for blocking the flow of air through the corresponding portion of the top layer 128 and thus directing the air through other portions of the cover layer 112. Of course, it is contemplated that the air distribution apparatus may not include any barrier coupled to the top layer.
The air distribution apparatus 110 also includes a spacer layer (spacer layer) 140 disposed within the interior chamber 132 between the top layer 128 and the bottom layer 122. The spacer layer 140 is formed of an air permeable material and is configured to space the top layer 128 and the bottom layer 122 from each other and prevent the interior chamber 132 from collapsing when, for example, a vehicle occupant is positioned on the vehicle seat. In this example, the spacer layer 140 is a spacer mesh. Other examples of spacer layer 140 may be a porous material, a reticulated foam, or any suitable air permeable support.
Referring to fig. 6-8, a second embodiment of an air distribution apparatus 210 is similar to the air distribution apparatus 110 shown in fig. 3, 4A, and 5A and includes similar components designated by the same reference numeral increased by 100. The second embodiment of the air distribution device 210 (fig. 6-8) includes a top layer 228 formed of an air impermeable material, and is different from the top layer 228 formed of an air permeable material 251 shown in fig. 5C. The air distribution device 210 includes a bottom layer 222 formed of an air impermeable material. The bottom layer has a bottom peripheral edge 226 and defines a single aperture 224 spaced from the bottom layer peripheral edge 226. The single aperture 224 is in fluid communication with the fan 108.
Referring to fig. 7 and 8, although the air distribution apparatus 110 shown in fig. 4A and 5A also includes the top layer 128 formed of an air permeable material without any apertures cut or otherwise formed therein, the air distribution apparatus 210 includes the top layer 228 formed of an air impermeable material with a single opening 242 formed therein. The air impermeable top layer 228 is configured to direct air toward the corresponding portion of the cover layer 212 through only a single opening 242. In this example, the top layer 228 includes a rim 244 spaced radially inward from the top peripheral edge 230 by any suitable constant or variable distance to define a corresponding shape of the opening 242. Although the exemplary single opening 230 shown in fig. 7 has the same shape as the top layer, it is contemplated that the opening may have any suitable shape and size for directing air toward any portion of the cover layer.
Referring to FIG. 7, the top peripheral edge 230 of the top layer 228 is sealingly coupled to the bottom peripheral edge 226 of the bottom layer 222, thereby enclosing an interior chamber 232. More specifically, air distribution apparatus 210 includes one or more mechanical fasteners 233 that are non-adhesive (non-tacky) for attaching bottom perimeter edge 226 and top perimeter edge 230 to each other. Examples of these mechanical fasteners 233 (fig. 4A-4C) can include sutures (sutures), staples, hook-and-loop fasteners, other suitable mechanical fasteners, or any combination thereof. In this example, each of top perimeter edge 226 and bottom perimeter edge 230 are not folded radially inward (fig. 4D) but remain unfolded and extend radially outward (fig. 4A). However, it is contemplated that the bottom and top perimeter edges may be folded radially inward (fig. 4D).
The air distribution apparatus 210 also includes a spacer layer 240 disposed within the interior chamber 232 between the top layer 228 and the bottom layer 222. The spacer layer 240 is air permeable and is configured to space the top layer 228 and the bottom layer 222 from each other and prevent the interior chamber 232 from collapsing when, for example, a vehicle occupant is positioned on the vehicle seat. Although this embodiment of the spacer layer 240 is a spacer mesh, other embodiments of the spacer layer may be a porous material, a reticulated foam, or any suitable air permeable support.
It will be appreciated that the above-described embodiments of the air distribution apparatus may be used alone, as described above, or may be engaged with one another to pull and/or push air towards a vehicle occupant.
The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the present invention are possible in light of the above teachings, as will now be apparent to those skilled in the art. It is, therefore, to be understood that within the scope of the appended claims, in which reference numerals are merely for convenience and are not to be in any way limiting, the invention may be practiced otherwise than as specifically described.
