Definitions
- the invention relates to a vehicle seat and a pad for such a vehicle seat.
- polyurethane foam foams are used for seat upholstery, with the help of which appropriate moldings for the seat cushion can be formed.
- the moldings made of foam have the disadvantage that they are less permeable to air, but have a low weight.
- Another possibility is to provide a mixture of natural fibers, such as coconut fibers, animal hair and the like with a binder, in particular latex, and to form a cushion part, which is known under the general term "rubber hair".
- a binder in particular latex
- rubber hair Despite the higher weight of such upholstery parts made of rubber hair, these have a high air permeability and are ideal. ing for a purposeful air conditioning of a vehicle seat made of such upholstery parts.
- a seat cushion for vehicle seats is known in which the core part made of a plastic foam is traversed with several wells. These depressions primarily serve to adapt to certain anatomy of the seat and can only partially facilitate air circulation, since the air exchange can take place only through an air-permeable support arranged above this core part.
- this air-permeable support communicates with a channel in which a fan is arranged.
- German Offenlegungsschrift DE 102 43 315 A1 likewise discloses a cushion for a vehicle seat, which has a cushion core, which is traversed by a channel system.
- the channel system is formed of horizontal, mutually rectangularly arranged sub-channels and from these vertically extending into the core further channels.
- the ventilation is generated by means of a fan, which introduces air through these vertical channels in the cushion core, which then flows out and through further vertical channels.
- Active seat ventilation devices are disadvantageous in that the construction of upholstery or vehicle seats containing them is complicated and expensive.
- the additional aggregates to be provided for such ventilation are associated with increased weight and space requirements.
- the essence of the invention consists in that an exit opening opposite an air-guiding layer inside a cushion, which can be used in a vehicle seat both as a seat cushion and as a backrest, is arranged such that the outflow of warm and moist air an automatic Nachströmen of dry and cool ambient air causes in the air-bearing layer.
- the embodiment according to the invention makes use of the "chimney effect" known from thermodynamics or thermals, in which cooler, and thus drier, air flows from the environment into the duct system due to the suction due to the suction effect. In this way, the water vapor partial pressure, or the diffusion gradient of the water vapor in the interior of the pad can be considerably increased.
- the cushion according to the invention consists of a composite of several layers, namely a foam core, the air-bearing layer and a covering this cover. In this case, different arrangements of the individual layers are possible.
- the air-bearing layer is disposed between the cover and the foam core, while in another embodiment, the foam core is disposed between the cover and the air-bearing layer.
- the foam core may be traversed by horizontal and / or vertical channels, so that according to the embodiment, either cool and dry air or warm and moist air can be passed through this channel system.
- the cover is made of an air-permeable and hydrophilic Vlieskaschtechnik.
- the air-conducting layer either consists of a knitted fabric, a reticulated foam or rubber hair.
- a pad constructed according to the preceding embodiments can be used both for a seat cushion and for a backrest of a vehicle seat.
- the exit opening of the upholstery is arranged on the rear side of the backrest viewed in the direction of travel and in the upper end region of the upholstery. Furthermore, according to the invention, at least one inlet opening is provided, which also opens towards the back and through which the cool and dry air is sucked.
- the boss ⁇ réelle is provided in the area of the backrest at the greatest distance from the entrance opening.
- the seat cushion is the outlet opening at the rear end, preferably the air-guiding layer.
- an entrance opening arranged at the greatest possible distance from the exit opening, which may be provided on the front side or the underside of the seat cushion.
- Fig. 1 is a schematic cross-sectional view of a first embodiment according to the invention
- 2 is a schematic cross-sectional view of a second embodiment according to the invention.
- Fig. 3 shows a schematic cross-sectional view of a third embodiment according to the invention.
- FIG. 1 shows a first embodiment of a vehicle seat according to the invention.
- the vehicle seat consists of a seat cushion 1 and a backrest. 2
- the seat cushion 1 and also the backrest 2 consist essentially of the same layer structure according to the invention.
- This layer structure is composed of an upper cover 3, consisting of a fleece lamination, a foam core 4 arranged underneath with vertical air and moisture-carrying channels 5 and an air-conducting layer 6, which is in turn made of a rubber effect.
- the composite of the layers 3, 4 and 6 is arranged on a spring core 7 for the seat cushion 1.
- the cover 3 is permeable to air and moisture, so that warm and moist air can be introduced through the channels 5 in the foam core 4 in the Gummigewirk 6.
- the backrest 2 also consists of an air- and moisture-permeable cover 9, which is arranged over a foam core 10 with channels 11 provided substantially horizontally therein.
- an air-guiding layer 12 is provided as a rubber effect, for example, which is supported on a spring core 13.
- an outlet opening 14 At the upper end of the backrest 2 there is an outlet opening 14.
- an inlet opening 15 is provided in the lower region of the backrest 2.
- the openings 14 and 15 open in the rear clamping part of the backrest 2.
- a second embodiment of a vehicle seat in which immediately below a reference 16, the air-guiding layer 17 is disposed of a rubber knit. Including a foam core 18 is provided, wherein in the foam core 18 at least one thens ⁇ réelle 19 is provided, which is preferably arranged for the intake of dry and cool air supply in the front region of the seat cushion 1 and opens downwards.
- a corresponding opening in the region of the seat cushion shell or of the spring core is provided.
- the backrest 2 is constructed in a similar manner from a cover 20, an air-guiding layer 21 and a foam core 22. On the back are an outlet opening 23 and an inlet opening 24 from each other at such a distance, which is sufficient to produce the "chimney effect".
- FIG. 1 A third embodiment of the vehicle seat according to the invention, or the pad according to the invention, is shown in FIG. The construction corresponds essentially to the embodiment according to FIG. 2, but with the difference that the foam core 18 of the seat cushion 2 is penetrated by a plurality of vertical channels 25 and at least one horizontal channel 26.
