    [0001] Vehicle seat element, seat comprising such a seat element and method of manufacture. The present invention relates to vehicle seat elements, to vehicle seats comprising such elements and to methods of making such elements. More particularly, the invention relates to a seat element comprising: a load-bearing structure, a soft and cushioning padding, carried by the supporting structure and adapted to support a user sitting on the seat, at least one fan having at least one air vent (air inlet or air outlet) arranged to circulate air in the padding. US2014203599A1 describes an example of a seat element of this type, in this case a seat back provided with fans mounted on the supporting structure. This type of assembly has the particular disadvantage that vibrations due to the operation of the fan can be transmitted to the carrier structure and possibly to other parts of the vehicle, thus generating noise and vibrations felt by the occupants of the vehicle. . The present invention is intended to overcome this disadvantage. For this purpose, a seat element of the kind in question is characterized in that the fan is carried by the padding and is independent of the supporting structure. This avoids the aforementioned drawbacks, since the padding, because of its flexible and damping nature, prevents the transmission of vibrations from the fan to the occupant of the seat or to other parts of the seat or the vehicle. In addition, this also provides easier attachment of the fan on the seat element. In addition, the same attachment is applicable to different types of fans and different forms of supporting structure, which allows greater standardization of manufacturing and therefore lower costs. Finally, it avoids positioning defects between the quilting and the fan and therefore air leakage at the connection of the fan on the padding, since the fan is fixed on the padding and not on the support structure.
    [0002] In various embodiments of the seat element according to the invention, one or more of the following arrangements may also be used: the seat element comprises at least one fastened fastener; the padding and the fan is attached to the at least one clip; the fan is fixed to the said at least one clipping fastener; the fan is fixed to said at least one fastener by means of a support, said support being fixed to said at least one fastener and carrying said fan: these arrangements make it possible to standardize as well as possible the fastening on the quilting; the support may for example in all cases include the same attachment to the padding, and according to the fan 35 used, an attachment interface of the fan adapted to this fan; the support comprises at least one air passage communicating with said at least one fan air intake, the padding comprising an air-tight rear sealing layer and provided with at least one opening, said at least one air passage being sealingly connected to said at least one opening; the support comprises a peripheral surface applied sealingly against the rear sealing layer around said opening, because of the fixing of the support to the at least one fastener; the seat member further comprises an open connection member which has a peripheral surface sealingly attached to the rear sealing layer around said opening, and the support of the fan is fixed to said connecting member so as to connecting the air passage of said support to said opening; the padding comprises at least one cushion of synthetic foam, overmolded on at least a part of said fastener; the padding further comprises an airtight rear sealing layer and an air-permeable three-dimensional fabric intermediate layer interposed between the synthetic foam pad and the rear sealing layer; fan being attached to said at least one fastener by at least one fastener passing through the rear sealing layer and the intermediate layer of three-dimensional fabric; - The seat element is a folder.
    [0003] Furthermore, the subject of the invention is also a seat comprising at least one seat element as defined above, which may be, for example, the back of the seat.
    [0004] Finally, another subject of the invention is a method of manufacturing a seat element as described above, comprising at least the following steps: - overmoulding a cushion of synthetic foam belonging to the padding on said less a tie; 5 - clip the fan on said at least one fastener. Of course, the various features, variations and / or embodiments of the present invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other. The present invention will be better understood and other features and advantages will become apparent upon reading the following detailed description comprising embodiments given by way of illustration with reference to the appended figures, presented by way of non-limiting examples. which may be used to complete the understanding of the present invention and the description of its implementation and, where appropriate, to contribute to its definition, in which: FIG. 1 is a schematic partially cutaway view of a vehicle seat; comprising a seat element equipped with a fan according to the invention; - Figure 2 is an exploded perspective view of a part of the seat element of Figure 1, according to a first embodiment of the FIG. 3 is a detail view in vertical section taken along line III-III of FIG. 4; FIGS. 4 and 5 are exploded views in perspective; 4 and 6, respectively, the views of the fan of the figure and its supporting device, seen from the rear and the front respectively, are views similar to FIGS. 3 to 5, respectively, in a second embodiment of FIG. FIG. 7A is an enlarged view of detail A of FIG. 7 and FIG. 8A is a detailed sectional view of the peripheral support surface of the fan, and FIGS. 9 to 11 are similar views. in Figure 7, respectively in third, fourth and fifth embodiments.
    [0005] It should be noted that, in the various figures, the same references designate identical and / or similar structural and / or functional elements in the different embodiments. Thus, unless otherwise stated, such elements may have identical structural, dimensional and material properties. For the sake of clarity, only the elements useful for understanding the described embodiments have been shown and will be detailed.
    [0006] Figure 1 is a schematic side view of a vehicle seat 1, for example a motor vehicle front seat. The seat 1 has a backrest 2 mounted on a seat 3, which seat 3 is itself mounted on a floor 4 of the vehicle, for example by means of slides 5. The backrest 2 is equipped with a fan 6, including the utility will be seen further. The backrest 2 comprises a support structure 2a, for example a metal frame, which carries a padding 7 forming the front face of the backrest and serving as support for a user sitting on the seat 1. The padding 7 is generally made of flexible material and shock absorber, to ensure the comfort of the user. The padding 7 may be for example carried by a spring web 2b attached to the carrier structure 2a. The padding 7 may for example comprise: - a front layer of lining 8, for example of fabric or other material permeable to air, - a layer of synthetic foam 9 disposed behind the lining layer 8 and essentially providing the comfort of the user by its flexible and damping character, 10 - a rear sealing layer 11 airtight, for example supported by the spring web 2b, - optionally, an intermediate layer 10 of three-dimensional fabric permeable to air, interposed between the synthetic foam cushion and the rear sealing layer. The fan 6 comprises at least at least one air outlet 6a, peripheral or axial, and an air mouth 6b for example axial, here forming an air inlet 20 arranged to suck air through the padding 7 , so that the air is sucked by the front of the backrest to improve the comfort of the user. More specifically, the air vent 6b of the fan is sealingly connected to an opening (not referenced in FIG. 1) formed in the rear sealing layer 11. It will be noted that according to the technology used for the fan 6, this could be used not to suck air through the padding 7, but to blow air into the padding 7. In this case, the air vent 6b would be an air outlet, while that reference 6a would designate an air inlet.
    [0007] The invention relates to how the fan 6 is attached to the back 2, and more generally to any seat element. This attachment will now be described in more detail in five embodiments.
    [0008] In the five embodiments described, the fan 6 is carried by the padding 7 and is independent of the supporting structure 2a. In the various embodiments described, at least one fastener is secured to the padding 7 (for example partially molded in the synthetic foam 9) and the fan 6 is attached to the at least one fastener, for example by clipping. More specifically, the fan 6 may be attached to a support itself attached to the at least one fastener and sealingly connecting the air vent 6b of the fan 6 to the opening of the sealed back layer. In the first embodiment, shown in Figures 2 to 5, the device comprises two fasteners 16 partially overmolded in the synthetic foam 9, and the support 12 is suspended from these fasteners 16. The fasteners 16 may be for example parts molded plastics, comprising a base 17 25 substantially parallel to the mean plane of the backrest, embedded in the synthetic foam 9, and two elastic fingers hook-shaped whose free ends are provided with lugs facing. The resilient fingers protrude rearwardly into an opening 10b in the three-dimensional tissue layer 10, corresponding to an opening 11b in the back seal layer 11. The carrier 12 may be plate-shaped, made for example molded plastic having an air passage 12a formed by a central hole disposed facing the air vent 6b of the fan 6 and sealingly communicating therewith.
    [0009] The fan 6 can be fixed to the support 12 by any known means, for example by pads 13 made of elastomer, which can also play the role of "silent blocks", which are clipped into tabs 14 of the fan.
    [0010] The support 12 may comprise, in the upper part, two fasteners 18, each comprising for example an anchor bar 15 adapted to engage axially by clipping between the elastic fingers 19 of the fasteners 16, through the openings 11b, 10b formed respectively in the rear sealing layer 11 and the three-dimensional tissue intermediate layer 10. The device may further comprise a connecting member 20, made for example of plastics material, 20 which comprises a peripheral surface 21 fixed in such a way sealing to the rear sealing layer 11 around the above-mentioned opening 11a of this layer which serves for the passage of air. The peripheral surface 21 may optionally comprise a lining 21a, elastomer or other, to facilitate the waterproof attachment to the rear sealing layer 11. This sealing attachment can be made for example by gluing, sewing or other. The connection member further comprises a central opening 22, for example in the form of a grid. The support 12 of the fan is fixed to said connection member 20 so as to connect the air passage 12a of said support 12 to said opening 11a of the rear sealing layer 11. The fan 6 can thus 3036336 9 aspire the air through the three-dimensional fabric 10, the sucked air having previously passed through the filling layer 8 and then the synthetic foam layer 9.
    [0011] The fixing of the support 12 on the connection member 20 can be done by any known means, for example by a bayonet attachment as in the example shown, where the fixing is done by axial engagement of the legs 24 of the support in recesses 23 of the connecting member, 10 and rotation of the support to engage the tabs 24 under the support 23, that is to say between the support 23 and the rear sealing layer. In the second embodiment, shown in FIGS. 6 to 8, only one central fastener 116 is provided (but several fasteners 116 would be possible). The fastener 116, shown in greater detail in FIG. 7A, may comprise a base 116 substantially parallel to the mean plane of the backrest, embedded in the synthetic foam 9, and a clipping member 119, for example in the form of a cup advantageously split by at least one axial slot 119a. The clipping member 119 projects rearwardly into an opening 10a formed in the intermediate layer 10 of three-dimensional fabric, for example in the center of the opening 11a. The support 120 which carries the fan 6 may, for example, be molded from a plastics material and may have a generally plate-like shape. The support 120 has a peripheral surface 121 sealingly applied against the rear sealing layer 11 around the opening 11a provided for the passage of air, due to the attachment of the support 120 to said fastener 116. To facilitate sealing between the annular bearing surface 121 and the rear seal layer 11, the annular bearing surface 121 may form or comprise a flexible annular sealing lip having a certain conicity towards the rear sealing layer 11 and slimming outwards (Figure 8A).
    [0012] The support 120 has a grid-like opening 122 in the center of the above-mentioned span 121, and said grid has a fastener 124, for example a rod having a ball-shaped free end which is adapted to snap into the The support 120 further includes, on its side opposite to that carrying the fastener, means for supporting the fan 6, which is shown schematically in FIGS. 6 to 8. In the embodiment of FIGS. 6 to 8, these fastening means comprise elastic hooks 123 adapted to snap onto the fan 6, for example on a flange 6c of said fan.
    [0013] The embodiments of Figures 9 to 11 are similar to the embodiment of Figures 6 to 8 and will not be described in detail. These three embodiments are distinguished from the second embodiment by the method of attachment of the fan 6 to the support: in the third embodiment, shown in FIG. 9, the fan 6 is fixed by pins 13 elastomer as in the first embodiment, these elastomeric pads being clipped in tabs 223 provided on the face of the support 220 opposite to the fastener 124; - In the fourth and fifth embodiments, the fan 6 is fitted into a housing 5 provided on the face of the support 320, 420 opposite to the fastener 124, the housing may be circular 323 or square 423 (or other) following the shape of the fan 6; in these embodiments, the support 320, 420 may be made by bimaterial molding, for example plastic (polypropylene for example) and elastomer (EPDM for example). Note that, although the foregoing description has been made with reference to a seat back 2, the invention would be applicable to any other seat member, including the seat 3, in which case the front and rear positions described herein. above would be replaced by upper and lower positions.
