DETAILED DESCRIPTION

[0036] According to FIGS. 1 as well as 4 to 7, 10, 11, a ventilatable surface region 1 of a seating or reclining furniture 2 according to the invention (see FIGS. 2 and 3) has a shaping foam layer 3, an air-distributing knitted spacer fabric 4, an air-conveying knitted spacer fabric 5, as well as an air-permeable cover layer 6. The cover layer 6 is additionally permeable for water vapor and thus provides for a heat and mass transfer. The shaping foam layer 3 thereby serves for the shaping and simultaneously for the support of a person positioned on the seating or reclining furniture. To ventilate the ventilatable surface region 1, the seating or reclining furniture 2 according to the invention also has a radial blower 7, which is connected in an air-transferring manner to the air-distributing knitted spacer fabric 4, wherein the radial blower 7 is arranged on the edge side of the air-distributing knitted spacer fabric 4 in such a way that a blowing of air into the air-distributing knitted spacer fabric 4 (see FIGS. 1 to 9) or an extraction of air therefrom (see FIGS. 10 and 11) takes place essentially parallel to a surface plane of the air-distributing knitted spacer fabric 4. This provides for the large advantage that the radial blower 7 can be arranged in the plane of the air-distributing knitted spacer fabric 4 and thus in a particularly space-saving and installation space-optimized manner with respect to a required installation space height. Due to the air-distributing knitted spacer fabric 4 and the air-conveying knitted spacer fabric 5, which is connected thereto, for example sewn, adhered, or weaved, a non-directed flow of the can be guided via the radial blower 7 to a non-illustrated person sitting on the seating or reclining furniture 2 according to the invention. This provides in particular for an optimized ventilation or purging, but without creating the feeling of a draught.

[0037] It goes without saying that the air-distributing knitted spacer fabric 4 and the air-conveying knitted spacer fabric 5 can also be placed loosely one on top of the other or can be thermally laminated together. A positive connection by means of the cover layer 6 and the shaping foam layer 3 as well as optionally support cushions are conceivable.

[0038] The air-conveying knitted spacer fabric 5 and/or the air-distributing knitted spacer fabric 4 can thereby have a compression hardness between of between 5 kPa and 35 kPa, preferably greater than 10 kPa and less than 30 kPa, particularly preferably greater than or equal to 15 kPa and less than or equal to 25 kPa, wherein in particular the shaping foam layer 3 can have the same compression hardness as the air-conveying knitted spacer fabric 5 in the transition to the air-conveying knitted spacer fabric 5. A haptically perceivable transition due to, for example, a perceivable hardness difference between the shaping foam layer 3 and the air-conveying knitted spacer fabric 5 can be reliably avoided thereby.

[0039] A lattice, which is not described in more detail, via which in particular an unintentional engagement of fibers of the air-distributing knitted spacer fabric 4 with a rotating fan blade of the radial blower 7 can be reliably avoided, is preferably arranged between the radial blower 7 and the air-distributing knitted spacer fabric 4. In addition or in the alternative, the radial blower 7 and the air-distributing knitted spacer fabric 4 can also be arranged spaced apart from one another, whereby the risk of a contact of a fiber of the air-distributing knitted spacer fabric 4 with a rotating fan blade of the radial blower 7 can at least be minimized.

[0040] According to FIGS. 1 as well as 4 to 7 and 10, 11, the air-distributing knitted spacer fabric 4 is thereby thicker than the air-conveying knitted spacer fabric 5, whereby it goes without saying that this is purely exemplary and can also be different. Purely theoretically, it is also conceivable that the knitted spacer fabrics 4, 5 have different compression hardnesses.

[0041] When looking at FIGS. 2 to 7, it can be seen that the air-distributing knitted spacer fabric 4 is at least partially arranged in a positive manner and so as to be flush with the surface in a recess 8 of the shaping foam layer 3, in the same way as the radial blower 7. Via the recess 8 in the shaping foam layer 3, the radial blower 7 as well as the air-distributing knitted spacer fabric 4 can be arranged so that, together with the surrounding shaping foam layer 3, they form a continuous surface, on top of which the air-conveying knitted spacer fabric 5 can be placed continuously and without a crease.

[0042] According to the illustrations in FIGS. 2 and 3, the seating or reclining furniture 2 is formed as so-called gaming chair, whereby gaming taking place in particular in private spaces can be designed to be significantly more comfortable, because private spaces of this type are usually not climatized and are heated up by means of waste heat from a computer as well as due to a tense gaming behavior. A thermal discomfort can result comparatively quickly thereby.

[0043] The air-permeable cover layer 6 can have, for example, fabric, perforated leather or synthetic leather and/or a woven fabric. Due to an individually and locally different air-permeability or water vapor permeability, respectively, local and individually heatable zones can additionally be created. For example regions, in which more moisture is created, can thereby be ventilated more strongly, whereby an optimized ventilation comfort is created as a whole. The ventilatable surface region 1 can thereby be, for example, a seating surface 9, a backrest 10, or a lumbar support 11, or can be arranged in an armrest 12 (see FIGS. 2 and 3). It goes without saying that other attachment locations, such as, for example, in the region of a headrest, are also conceivable.

[0044] When looking at FIGS. 4 to 7, it can be seen that a suction duct 13 is provided, which is connected to the radial blower 7 and which is held via the shaping foam layer 3. For example, a recess 8′, which is formed in a complementary manner to the outer dimensions of the suction duct 13, is provided for this purpose in the shaping foam layer 3. By means of a fixed connection of the suction duct 13 to the radial blower 7 and an assembly of this assembly group into recesses 8′ or 8, respectively, of the shaping foam layer 3, which are formed in a complementary manner thereto, an unambiguous and simple fixation of the radial blower 7 and of the suction duct 13 to the shaping foam layer 3 can be attained. The same applies for the embodiment shown in FIGS. 10 and 11, in the case of which a blow-out duct 13′ is provided, which is connected to the radial blower 7 and which is held via the shaping foam layer 3.

[0045] A surface of the air-distributing knitted spacer fabric 4 can thereby be smaller than a surface of the air-conveying knitted spacer fabric 5, wherein the air-distributing knitted spacer fabric 4 deflects the air ejected by the radial blower 7 during the pressure operation and transfers it into the air-conveying knitted spacer fabric 5. There, it is then distributed in a flat manner and can be blown out via the air-permeable cover layer 6. It goes without saying that, during a reverse operation of the radial blower 7, an intake of air via is take place as well via the air-permeable cover layer 6 and an ejection via the blow-out duct 13′. The suction duct 13 or blow-out duct 13′ can thereby be formed, for example, from plastic and can form an assembly group with the radial blower 7.

[0046] An energy storage 14 can likewise be provided, which is likewise accommodated in a positive manner, for example in a corresponding recess 8″ of the shaping foam layer 3, and which is fixed thereby. A reinforcing effect can additionally be provided to the shaping layer 3 via a frame 15, for example a metal frame.

[0047] Unhindered gaming fun can be attained by means of the ventilatable surface region 1 according to the invention and the seating or reclining furniture 2 according to the invention, which has said ventilatable surface region, by means of an optimal ventilation of a gamer. A radial blower 7 used in this way is arranged in a noise-optimized manner in the shaping foam layer 3 and is covered by means of the air-distributing knitted spacer fabric 4, the air-conveying knitted spacer fabric 5, and the air-permeable cover layer 6, so that fan noises are virtually not perceivable. Due to the arrangement of the radial blower 7 in the dampening shaping foam 3, a vibration transfer to solid materials also does not take place, which likewise contributes to a low-noise operation. A heat and moisture accumulation can be avoided by means of the ventilatable surface regions 1. The air-distributing knitted spacer fabric 4 and the air-conveying knitted spacer fabric 5 furthermore provide for a comparatively simple manufacturing process and a simple production of the shaping seating foam 3 with simultaneously consistently good feel.

[0048] The surface of the air-distributing knitted spacer fabric 4 is thereby smaller than the surface of the air-conveying knitted spacer fabric 5, wherein in addition or in the alternative, a surface of the air-conveying knitted spacer fabric 5 can also be smaller than a surface of the cover layer 6. The advantage lies in particular in the two-layered construction because a large surface is already supplied by means of the air-distributing knitted spacer fabric 4, and the air can be distributed even further in a flat manner in the air-conveying knitted spacer fabric 5, and an air flow can be homogenized. In addition, the air-distributing knitted spacer fabric 4 is flexible and cannot be felt in an uncomfortable manner and can simultaneously distribute the air escaping in a jet-like manner from the radial blower 7 into the air-conveying knitted spacer fabric 5. The air distribution thus becomes more even compared to a direct flow-out from the blower into the knitted spacer fabric 5.

[0049] A construction of the air-distributing knitted spacer fabric 4 and of the air-distributing knitted spacer fabric 5 can thereby be identical. There may be differences in one of the layers or in an air resistance, e.g. due to the fine-mesh characteristic, a thickness of spacer threads, and thus also the compression hardness of the respective knitted spacer fabric 4, 5. The air-distributing knitted spacer fabric 4 and/or the air-conveying knitted spacer fabric 5 can be woven from synthetic (threads) or from natural threads.
