Air-conditioned vehicle seat, with an air-impermeable, lower seat or backrest upholstered part, an air-permeable intermediate layer and an air-flow padding on the part of the intermediate layer, which is subdivided by bounded to the air-impermeable cushion part tacks in delimited cushion zones, wherein for connecting the intermediate layer between the individual cushion zones across are provided to the stitching air bridges, characterized in that the air bridges (15) in the longitudinal direction of the stitching (11) narrower than the Abheftseitigen edge zones (10) of the intermediate layer (4) formed and the stitching without interposition of the air bridges on both sides of this adjacent wall portions (16) of the cushion part (3) are anchored.
The invention relates to an air-conditioned vehicle seat having a lower, impermeable seat or backrest upholstered part, an air-flooded intermediate layer arranged thereon and a padding zone divided by separations into separate padded zones, air-flowed through the intermediate layer, according to the preamble of patent claim 1.
In an air-conditioned vehicle seat from the DE 100 24 879 C1 Known type, the stitching are designed as stitching in the air flow, consisting of a soft foam layer and the fabric cover upholstery. The depth of insertion of the stitching is limited to the thickness of the upholstery and also lacks a load-resistant anchoring of the stitching on the lower cushion part.
From the DE 10 2004 039 058 A1 is a vehicle seat with a support member in the form of a seat and / or backrest part with an at least one piece cushion core for supporting a seat occupant, with a cover which at least partially obscures the cushion core, and with a Abspanngraben on which the surface of the support member has an elongated recess has, known.
Furthermore, from the EP 1 364 827 B1 an actively ventilated motor vehicle seat is known, in which the upholstery cover is fixed on the way through the air-filled intermediate layer in the manner of the lower cushion part, that in the longitudinal direction of the stitching distributed studs are bolted to the lower cushion part, which pass through the intermediate layer and retracted into the upholstery Abheftstangen are detachably hooked. As a result, although stronger constrictions of the air-guiding intermediate layer in the region of the stitchings are avoided, the seating comfort is considerably impaired by the stud bolts projecting upwards beyond the intermediate layer.
Finally, at the time of the DE 101 56 658 C1 known vehicle seat of the type mentioned, in which the air-permeable intermediate layer is divided along the stitching into individual ventilation separate from each other sections, insert strips in the form of spacer fabric sunk arranged in the lower cushion part, the length conform to the stitching below the filing side edge portions of the intermediate layer sections and act as air bridges between them. The stitches are produced by puller wires, which extend through the insertion strips and are anchored in the lower padding part. The production and arrangement of the air bridge-forming insertion strips requires an increased production cost, and since the insertion strips are compressed by the tensile forces of Abheftdrähte cross-sectional narrowing, it can lead to a disability of the air exchange between the individual sections of the intermediate layer.
The object of the invention is to achieve an unobstructed seat ventilation and a permanently secure fixation of the stitching in a vehicle seat of the type claimed in manufacturing technology simple manner and without affecting the seating comfort.
This object is achieved by a vehicle seat with the features of claim 1.
According to the invention, the air bridges are dimensioned relatively narrow and recessed in the longitudinal direction of the tenter both sides in the cushion part, and the tethers are anchored to the side immediately adjacent to the air bridges wall portions of the cushion part, so that the air bridges largely relieved of the tentering resulting tension forces and a permanently tensile and non-slip attachment of the upholstery cover along the stitching is ensured. This results in an unobstructed air flow through the intermediate layer on the way over the air bridges at the same time high seating comfort in conjunction with a manufacturing moderately simple, long-term stable seat construction.
In another, preferred manufacturing embodiment of the invention, the air bridges and the intermediate layer are prefabricated as a one-piece insert, usually from a spacer fabric.
The smaller cross-sectional width of the air bridges compared to the intermediate layer can be compensated by an increased cross-sectional height and / or, as is preferred, by a higher air permeability of the air bridges than the intermediate layer.
In order to anchor the stitching over the largest possible length directly on the cushion part, the adjoining the air bridges wall portions of the cushion part in the longitudinal direction of the stitching are preferably at least as wide as the air bridges dimensioned, and a particularly large depth of insertion of the upholstery reference can be achieved in that the bindings mounted in a feeder channel of the upholstery part and the air bridges are flush mounted on both sides flush with the intake duct in the upholstery part.
With regard to a particularly secure attachment of the stitching on the upholstery part, it is advisable to anchor it to a continuous in the upholstery part along the stitching Abheftelement, which for the sake of uniformly stable embedding in the upholstery material preferably both below the air bridges and in the air-bridge wall sections the cushion part runs at a uniform depth.
To relieve the air bridges of the tension forces resulting from the binding, the anchoring of the stitching is restricted in a particularly preferred manner to the air-bridge-free wall sections of the cushion part.
The invention will now be explained in more detail with reference to an embodiment in conjunction with the drawings. It shows in a highly schematic representation:
1 a perspective view of an air-conditioned vehicle seat according to the invention with an air-flooded spacer fabric in the cross-hatched areas;
2 the supervision of one including the air bridges integral knitted blank;
3 a section along one of the stitches of in 1 shown vehicle seat;
4 a cut across one of the stitches of the in 1 shown vehicle seat along the line I of 1 ; and
5 a cut across one of the stitches of the in 1 shown vehicle seat along the line II of 1 ,
The in Figs. shown, actively ventilated vehicle seat consists of a seat and a backrest module 1 . 2 , each one an air-impermeable cushion part 3 made of foam, an air-filled interlayer covering it in the cross-hatched areas 4 from a coarse mesh knitted fabric and one side of the intermediate layer 4 flowed through, in total with 5 designated cushion cover included, which is one of air openings 6 interspersed foam pad 7 and a covering material spanning them 8th having.
The air supply to the spacer knitted fabric 4 of the seat or backrest module 1 . 2 takes place for. B. to the in 1 indicated by arrows P air inlet points by means of - not shown - mini fans in an air duct of the upholstery part 3 ,
For tensioning the upholstery cover 5 are on the seat and backrest module 1 . 2 transverse and longitudinal stitching 11 provided the upholstery cover 5 in individual, delimited padded zones 12.1 ... 12.8 divide and each on the side of the upholstery 5 a continuous filing wire 13.1 have, by tensile, but in the direction of pressure compliant Abheftklammern 14 with another, in the upholstery section 3 continuously embedded filing wire 13.2 zugverspannt is. To increase the depth of penetration are the stitching 11 in a feeder channel 9 of the upholstery part 3 ( 4 ) arranged.
The in the individual upholstered zones 12 lying surface portions of the intermediate layer 4 are through below the bindings 11 across these running air bridges 15 (in 1 blackened) air moderately connected. As the 2 and 3 show is the width of the air bridges 15 in the longitudinal direction of the stitching 11 much smaller than the length of the Abheftseitigen edge zones 10 the intermediate layer 4 ( 2 ) and the bilateral adjacent, air bridge-free wall sections 16 of the upholstery part 3 ( 3 ). Between the wall sections 16 is the upholstery part 3 provided with recesses in which the air bridges 15 sunk in such a way that they are substantially flush with the adjacent intake ducts 9 connect.
How out 3 it can be seen, the filing wire extends 13.2 continuous in even depth in the upholstery section 3 both below the air bridges 15 as well as along the wall sections 16 , where the anchoring of the bindings 11 by means of the staples 14 on the wall sections 16 of the upholstery part 3 is limited, so that the Abheftkräfte essentially from the air bridge-free wall sections 16 taken and from the air bridges 15 be largely kept away. As a result, a highly stable anchoring of the bindings 11 directly on the upholstery 3 achieved without the air bridges 15 be burdened by the Abheftkräfte cross-section narrowing.
For making a seat or backrest module 1 respectively. 2 First, a one-piece knitted blank made of a spacer knitted fabric, z. B. the knitted blank 17 according to 2 for the seat module 1 which including the air bridges 15 the individual upholstered zones 12.5 .... 12.8 of the seat module 1 corresponding sections of the intermediate layer 4 includes. Then the blank is cut 17 on the under embedding of the filing wire 13.2 prefabricated upholstered part 3 filed, so the air bridges 15 between the upstanding wall sections 16 of the upholstery part 3 flush with the intake ducts 9 be taken, whereupon the seat or backrest module 1 . 2 by attaching the upholstery cover 5 and tightening the bindings 11 is completed.
To compensate for compared to the intermediate layer 4 smaller cross-sectional width of the air bridges 15 These can also be separated from the intermediate layer 4 from another spacer fabric of larger cross-sectional height or lower specific flow resistance than the intermediate layer 4 be made.
