Description
- The present invention relates to an air distribution system for a vehicle component having an air distribution layer and an accompanying layer thereon. Such arrangements are employed, for example, in air-conditioned seats, to distribute air in the seating surface underneath a seat covering and thereby direct the flow towards a passenger.
- U.S. Pat. No. 5,902,014 discloses air-conditioned seats in which a ventilating layer made of a highly porous air-permeable material is sewn between a seat pad and a covering. In another example, DE 197 26 810 provides an areal heating element between such a ventilating layer and the covering. Such seats are very costly to fabricate, since several layers must be sewn up, at least in part, successively. Such operations are time consuming and inefficient. Furthermore, positioning the ventilating layer on the pad poses difficulties in terms of accuracy.
- EP 1,352,780 discloses a seat in which parts of a pad of a seat are replaced by insertions of reticular material. These parts are supplied with air. This arrangement has disadvantages, too, as such parts may slip or require separate fastening elements.
- Accordingly, there exists a need for an improved air distribution system for ventilated components in the passenger compartment such as vehicle seats.
- The present invention provides an air distribution system that is simple to install, logistically simple to manage, and is secure in operation. In one embodiment, the invention provides an air distribution system for distributing air in a component such as a vehicle seat. The system includes an air distribution layer and a first layer arranged thereon. The first layer projects beyond the base area or perimeter of the air distribution layer to form at least one projection or flange. An adhesive is arranged on the flange on the side facing towards the air distribution layer. The air distribution system can be arranged between a seat pad and a seat cover. The pad can include a recess to accommodate the air distribution layer. The recess can also correspond in depth to the air distribution layer. Because the adhesive flange projects beyond the air distribution layer which is secured to the first layer, the unit can be easily positioned and secured to the seat pad during further manufacturing steps.
- The seat pad can include various pad zones separated by seat features such as depressions, elevations and/or height differences. At least one of the pad zones includes a recess substantially corresponding in size and depth to the air distribution layer. The recess can extend as far as the edge of the pad zone and be bounded along its borders by a pad elevation. The pad elevation can substantially correspond with the flange such that the adhesive area can bind to the pad elevation surrounding the recess. In this way, the air distribution system can advantageously be registered in position and fixed within the seat pad zone of interest. The seat pad zone may be a seat cushion or backrest portion of a vehicle seat.
- In another example, the air distribution layer can comprise at least two segments with the first layer arranged over the segments such that the segments are spaced from each other. The segments can be separated from each other within the same plane along the first layer. An electrical conductor such as a heating conductor can run from the first segment to the second segment of the air distribution layer. The conductor can be arranged at an angle with respect to the shortest path between the two segments and can also meander about its principal, angled direction to permit flexion during assembly and in operation or use of the seat.
- The adhesive can be provided as an adhesive layer on at least half of the flange such that at least one adhesive edge is provided around the air distribution layer. The adhesive area can comprise a self-adhesive or a knotted surface.
- The first layer can be formed essentially by the adhesion area and/or may include constituents such as pad material essentially covering the air distribution layer completely.
- In another embodiment, an areal heating element is arranged on the air distribution layer, either in the first layer or between the first layer and air distribution layer.
- In another example, a vehicle seat including at least one pad having a recess formed therein, and an air distribution system is provided. The air distribution system includes an air distribution layer secured to a first layer. The air distribution layer defines a base area substantially corresponding in size to the recess. The first layer projects beyond the base area along at least a portion of an edge thereof to form a flange. A side of the flange facing towards the pad includes an adhesion area. The air distribution system can also include an areal heating element arranged between the air distribution layer and the first layer. The adhesion area includes a self-adhesive or a knotted surface for engaging the pad along a pad elevation surrounding a portion of the recess.
- A method of assembling a ventilated vehicle seat is also provided. The method includes providing at least one vehicle seat pad having a recess formed therein, and providing an air distribution system comprising an air distribution layer secured to a first layer. The air distribution layer defines a base area substantially corresponding in size to the recess. The first layer projects beyond the base area along at least a portion of an edge thereof to form a flange, wherein a side of the flange facing towards the pad includes an adhesion area. Thereafter, the air distribution system is positioned within the recess and the flange adhesion area is engaged to the pad along a pad elevation surrounding a portion of the recess to fix the air distribution system within the seat pad.
- The present invention is advantages in that it provides an economical air distributing system that can be easily handled during seat manufacturing and can be accurately positioned with respect to a seat pad. Other objects and advantages will become apparent with reference to the following detailed description, taken in conjunction with the accompanying drawings.
- For a more complete understanding of this invention reference should now be had to the embodiments illustrated in greater detail in the accompanying figures and described below by way of examples of the invention wherein:

FIG. 2 shows a longitudinal section through the seat ofFIG. 1 . -
FIG. 3 shows a perspective view of a seat in an opened condition having an air distribution system according to another embodiment of the present invention. -
FIG. 4 shows a top view of an air distribution system according to an embodiment of the present invention. - While the present invention is described with respect to an air distribution system for a vehicle seat, the present invention may be adapted and utilized for other ventilated components such as arm rests, door trim, armature panels as well as non-automotive seat and ventilated components applications. In the following description, various operating parameters and components re described for two embodiments. These specific parameters and components are included as examples and are not meant to be limiting.

FIGS. 1 and 2 show a cross-section and longitudinal section, respectively, of acomponent 30 in the passenger compartment of a vehicle, in this case aseat 31. Apad 6 is provided in theseat 31. Thepad 6, on its side facing the passenger, comprises arecess 35. Therecess 35 is bounded bypad elevations 41. On the side of thepad elevations 41 away from therecess 35,depressions 7 are provided. Therecess 35 and thepad elevations 41 are provided in afirst pad zone 16. Asecond pad zone 17 is also provided, and is formed like thefirst pad zone 16 such that it includes arecess 35,pad elevations 41 anddepressions 7. Thus, thepad zones depressions 7 or other variations in height. Therecesses pad zones elevations 41, however, provide a boundary orborder region 39 along at least one side of eachrecess - In the example shown, the base area of the
second recess 35′ is displaced from that of thefirst recess 35. On theseat pad 6, anair distribution system 20 is disposed. Theair distribution system 20 comprises anair distribution layer 4 and afirst layer 2 arranged thereon. Theair distribution layer 4 can be made up, for example, of a knit spacer (as here), rubber filaments, foam or a plurality of spirals arranged side by side, or some other material through which air can flow. - The
air distribution layer 4 comprises, in the present embodiment by way of example, twosegments FIG. 2 ). The size of each airdistribution layer segment respective recesses segments recesses segments recesses segments segment - On the
air distribution layer 4, afirst layer 2 is arranged. Thefirst layer 2 is located on the side of theair distribution layer 4 away from thepad 6. Thefirst layer 2 projects at least partly beyond the base area or boundary of theair distribution layer 4 to create a projection orflange 25. Theflange 25 should extend beyond at least one edge of the air distribution layer and, preferably, beyond the entire periphery of the air distribution layer. On theflange 25 so formed, an adhesion area 5 is provided. This extends, in the embodiment shown by way of example, around thesegments air distribution layer 4. It is expediently formed by a strip of self-adhesive film. The adhesive area 5 is at least on the side of thefirst layer 2 facing toward theair distribution layer 4, but can be on both sides of thefirst layer 2. Thefirst layer 2 may be made up exclusively of the adhesion area 5. In the present example, however, it comprises apad layer 3 of pad material. - Additionally, an
areal heating element 12 is arranged on thefirst layer 2. Thepad layer 3 and theheating element 12 may be bonded, sewn, knitted or knotted to each other. Thesegments first layer 2 are so arranged on each other that thesegments pad zones first layer 2 extends as far as the base of thedepression 7 between the twopad zones depression 7 in the present case is a relaxation pit. The adhesion area 5 adheres to theelevations 41 defining the boundary of eachrecess elevations 41 and theair distribution layer 4 is ensured, and theair distribution layer 4 is firmly and undisplaceably fixed when placed within the corresponding recess. - The
air distribution system 20, particularly in theair distribution layer 4, provides a low flow resistance air current along the air distribution layer, i.e., transverse to the air distribution layer. In addition, it has a high vapor transmissivity and/or air transmissivity perpendicular to theair distribution layer 4. - The
air distribution system 20 is covered by aseat covering 1. Theseat cover 1 may be pasted on thepad 6 and theair distribution system 20. In the present example, however, it is stitched along thedepressions 7. -
FIG. 3 , in another embodiment by way of example, shows aseat 31, apad 6 having arecess 35 and anair distribution system 20. The components are substantially similar to the first embodiment, however, theair distribution layer 4 comprises only onesegment 43. - In the
recess 35, apassage 47 is provided for accommodating anelectric connection cable 9 of theair distribution system 20. Thepassage 47 extends from the base of therecess 35 through thepad 6 and emerges from thepad 6 again in a suitable place, e.g. on the reverse or face of thepad 6. - In the
recess 35, anopening 49 is provided as well. This serves for passage of air and connects theair distribution layer 4 to the surroundings of theseat 31. Expediently, therefore, air travels as directly and rectilinearly as possible to the side of thepad 6 away from theair distribution system 20. - In the
opening 49, a blower orfan 8 is provided. Thefan 8 serves to supply air to theair distribution system 20 or aspirate air from thesystem 20. - It will be apparent that the
air distribution system 20 comprising theair distribution layer 4, thefirst layer 2 with adhesion area 5 and the other functional elements such as theelectric heating element 12 will form a coherent, simply handled component. This component may simply be fitted into therecess 35, held in place by the adhesion area 5, and then may be permanently secured during subsequent operations. -
FIG. 4 shows another example of anair distribution system 20 corresponding to the first embodiment. In the top view, electrical conductors 11 are shown, leading from thefirst segment 43 of theair distribution layer 4 to thesecond segment 43′. These electric conductors 11 are fixed on thefirst layer 2. They do not extend linearly or on the shortest path from one segment to the other. Rather, their principal direction is at an angle to the shortest possible connection, and they meander about that principal direction. In this way, the conductors 11 acquire sufficient freedom of motion to bridge relaxation pits orother depressions 7 and seams without being damaged by overextension or stress under load. The invention is not limited to seats. In adapted form, it may for example be provided also for arm rests, door trim and armature panels. - The
air distribution system 20 may alternatively comprise a moist, interstorage layer, e.g. a fleece of active carbon particles. Further, the air distribution system may be fitted with sensors, fans or other functional elements. Also, pad distribution elements or multi-zone foams may be arranged thereon. Molded parts of rubber filament are especially suitable for the seat level. - Another fastening alternative can be provided by foaming parts of an adhesive shield into the pad and providing the corresponding parts on the adhesion area of the air distribution system, and/or making the first layer a textile, bondable material. The adhesion area 5 of the
first layer 2 will then interlock with thepad 6 rather than bond thereto in the case of an adhesive. As used herein, however, the term adhesion contemplates both bonding and material interlocking. - In operation, the air distribution system of the present invention provides assembly advantages over prior art vehicle seat assembly processes. In particular, the
air distribution system 20 comprising theair distribution layer 4 andfirst layer 2 having anadhesive flange 25 can be easily handled by assembly operators. Further, because theseat pad recess 35 substantially corresponds in size to theair distribution layer 4, theair distribution layer 4 can easily and accurately be located on thevehicle seat pad 6. In addition, theadhesive flange 25 secures theair distribution system 20 to thepad 6 during further upholstery operations. In this way, it is ensured that the air distribution system will not shift or otherwise become dislocated during final assembly. - While the invention has been described in connection with one or more embodiments, it is to be understood that the specific mechanisms and techniques which have been described are merely illustrative of the principles of the invention, numerous modifications may be made to the apparatus described without departing from the spirit and scope of the invention as defined by the appended claims.
