A detector device is inserted into the case, and a detection layer is formed between the air conditioning layer and the coating layer.

Description

The The present invention relates to air conditioning apparatus, for detecting and sitting according to the preambles of the independent claims as well a vehicle according to claim 10th

State of technology

Detector devices are installed in seats to recognize users (WO 2004/005068). It is also known to provide heaters or the like with heaters to warm the user ( DE 197 24 168 C1 , WO 02/06083 A1). However, since both functional systems must be located as close to the surface as possible in order to work reliably and efficiently, they may interfere with each other.

For example The temperature on the heating element must not be too high, otherwise the Measurement of the detector device falsified. This would require more homogeneous heating and thus more expensive material used for the heating resistors become. At the same time would Heating elements by a detector device arranged at the same time thermally insulated and need actually a higher one Heating capacity. Furthermore would two simple z. B. by gluing systems attached to each other Seat pad harder appear and a complex positioning relative to each other require.

Systems are known ( DE 43 38 285 . EP 0873903 ), in which an electric surface heating element is simultaneously used as a sensor for the contact / use of a heated surface. However, this concept is technically difficult to implement.

There are also heating elements known ( DE 100 29 237 ), which become electrically conductive under pressure in the region of the load and locally heat there. However, they do not provide measurement signals to external devices.

There are also systems which arrange components of a heating element and a detector on a common carrier (WO 01/89267, DE 10057222 ). However, such composite systems are hardly permeable to air and require additional measures to shield the detector device from the heating conductors. In addition, rejects are relatively expensive.

Besides are mat-like air conditioning z. B. from WO 02/053411 A2 known. A mat-like design of an air conditioning device brings with it the advantage that these integrated in the manufacture of the seat in a simple manner can be placed on the finished seat cushion. The Laying the air conditioning layer is thus independent of the production of the actual upholstery. In addition, the shape is also of the pad almost arbitrarily, so that a single embodiment a mat-like air conditioning universal for many different seats can be used. However, it does here the same problem with simultaneous use of a Air conditioning layer and a seat occupancy detection device.

Out DE 19805174 is known a vehicle seat, which has an air-permeable padding. In this heating elements are arranged. A fan blows air into the upholstery, wraps around the heating elements and blows the heated air to the seat surface. The integration of such heating elements in the seat upholstery is complicated and leads by hardening in the upholstery to loss of comfort.

problem

It Thus, it is a problem to temper / climateize a user-touched surface at the same time to monitor safely for use; and thereby the production costs moderate.

object the invention

to Enrichment of the prior art are therefore the objects of independent claims proposed. Further advantageous embodiments are the dependent claims and the Figure description removable.

description the invention

1 shows a seat 3 with a seat cushion 4 and a backrest cushion 4 ' , The seat cushion 4 is with an air conditioning device 1 fitted.

The air conditioning device 1 has an air guide device 8th on. The air guiding device 8th includes at least one below the surface of the seat 5 ' and / or below the surface 5 '' the backrest to orderly and with the ventilation device 8th related air conditioning layer 25 ,

The air conditioning layer is present here 25 a flat structure extending from the underside of the seat cushion 4 around the trailing edge of the seat cushion 4 nestles and flat on the top 5 ' of the seat cushion 4 rests. The climate control layer 25 Preferably, it covers substantially the entire surface facing a user 5 ' of the seat cushion 4 ,

The air guiding device 8th has an air guiding layer 29 preferably made of a porous, flexible spacer medium 31 is formed. For example, spacer fabrics made of synthetic fibers or spiral mats are used here. The air guiding layer 29 preferably forms at least part of the air conditioning layer 25 , The air guiding layer 29 is preferably as here from both sides of a cladding layer 33 . 33 ' covered. Preferably, the cladding layers seal 33 . 33 ' the air guiding layer 29 also at their edges against the environment 35 airtight. The cladding layers are made, for example, from polyurethane fabrics or similar materials and at their edges with each other or with the pad 4 . 4 ' of the seat 3 (or another interior component) preferably airtight glued or sealed.

The air guiding device 8th is preferably constructed so that the air guiding layer 29 and the cladding layers 33 . 33 ' to form a coherent assembly for air guidance.

In the present case, this creates an elongated bag, at one end of the bag 40 an opening 42 is provided, on which a fan can be arranged (not shown). At the other, the area to be air-conditioned 5 associated end are perforations 45 provided by the air with the environment of a passenger can be replaced (by blowing or sucking air through the air guide device 8th ).

A surface to be conditioned 5 . 5 ' . 5 '' of the seat 3 forms an area to be air conditioned 43 and is with an at least partially air-permeable fabric 49 Mistake. This area 43 this is one end of the air guide device 8th assigned. The air guiding device 8th points in this area 43 perforations 45 in the cladding layer 33 ' on.

At the opposite end of the air guide device 8th which preferably as here on the underside of the seat cushion 4 is arranged, is a connection area 37 intended. Here is the cladding layer 33 preferably at least one opening 42 on.

On the underside of the seat cushion 4 is at the connection area 37 Preferably, an unillustrated module for air conditioning provided, which is not shown for the better representability of the other components in the drawings. The module for air conditioning can be a Be Ventilation device in the form of a fan, a heater, preferably a PTC heating element, a heat exchanger, a regulator unit to control the operation of the fan and / or the heater, and / or have a temperature sensor to the temperature z. B. to measure the intake air.

The air guiding device 8th can, for example, have an axial fan or a radial fan or in a simplified embodiment also be formed by this itself. It may be located under the seat, behind the backrest, next to the seat or at another, even remote location. Alternatively, the ventilation device can also be connected to or formed by an air conditioning system of a motor vehicle.

At the air conditioning device 1 is in their area to be air-conditioned 5 an associated layer 27 intended.

In the embodiment is a heating element 11 arranged so that it is approximately parallel to the air conditioning layer 25 arranged accompanying layer 27 forms and a pocket-like space in the form of an insert pocket 28 creates between the two layers.

The pocket edges 14 the insert pocket 28 are formed by sticking or sewing the edges of the heating element on the edge of the air-conditioning layer. At least one but not more than two margins of the companion layer 27 are attached to the air conditioning layer. This creates an insert pocket 28 into which a detector device 9 can be inserted. This Einschiebeprocess can take place before the installation of the air conditioning device in the seat or after its installation in the seat. breakthroughs 15 In the heating elements are used for visual inspection of the correct position of the detector device for air conditioning or to the seat. A sticking of the detector device to the air conditioning or seat takes place as a last step, so that the position can be corrected to the seat still at the end.

The detector device 9 is preferably in the form of a flat detector layer 23 designed. It may be formed, for example, by a film having a plurality of pressure sensors arranged thereon. In the present case, two or more electrically conductive layers (not shown) are about the size of the detector layer 23 superimposed to form a pressure-sensitive capacitor.

There are openings in the detector layer 10 provided for a passage of air through the detector layer 23 to enable. They are usefully substantially congruent with the perforations 45 the air conditioning layer 25 arranged.

The detector layer 23 gets into the insertion pocket 28 the air conditioning device 1 plugged in. Before installing z. B. in a seat, it can be easily readjusted before the fabric 49 of the seat 3 is applied.

It is advantageous that the detector layer 23 inside the insert pocket 28 less slippage than simply laying the components together.

It is advantageous if in addition a heating element closer than the air guide layer 29 is arranged on the passenger to its heat effect faster and more effective on a user-touched surface 5 transferred to. This allows the heating element 11 or its heating power can be made smaller.

In heating mode, air is sucked from the underside of the seat into the module for air conditioning and tempered and / or dehumidified. Then it flows over the connection area 37 in the air guide device 8th one.

In the air guide device 8th it flows, guided by the mantle layers 33 , through the air guiding layer 29 to the top of the seat cushion 4 , There it flows in the area 43 through perforations 45 from the air guide device 8th out, penetrates the seat cover 49 and air-conditioning the surface to be conditioned 5 ,

The The invention is not limited to the above embodiments. Much more is a variety of variants and modifications conceivable by the idea according to the invention Use and therefore also fall within the scope of protection.

It For example, it may be appropriate that the air conditioning device and / or the detector device in a vehicle seat, a steering wheel, a Armrest, a seat cover, a warming blanket, in bedding, cinema seats, floors, door panels or similar is installed. She can sit in a seat pad or like this between the seat surface and the seat cushion. It may be appropriate that the heating element into a larger subsystem is fitted to the seat occupant with heating, cooling, ventilation, etc. to supply.

It can be provided that the heating element and the air conditioning layer are connected to each other only at one of its edges and at least partially use the same carrier, so that the Pocket formation not sewn, but only needs to be folded.

The Bag may also include means for firmly anchoring the detector mat have at a fixed position, for. B. snap fasteners or Velcro straps.

It is advantageous if the air conditioning layer an air guide layer as here in the form of an intermediate layer, which is an air-permeable, having cushioning material. This can cause hard parts or recesses be compensated in a detector device. This increases the seating comfort and additionally a heat insulation against a heating element. The air guiding layer is preferably at least partially made of reticulated foam, air permeable textile, Fleece or similar educated.

The climate control layer 25 preferably comprises both the air guiding layer 29 as well as the heating element 11 , It can, however, z. B. for certain climates include only one of the two.

As an accompanying layer 27 As an alternative to the accompanying layer of separate textile material, the heating element or the air-guiding layer could also serve.
