Definitions

  • the present invention relates to a vehicle seat with a ventilation device according to the preamble of patent claim 1.
  • air is sucked in from the rear of the vehicle seat by means of a blower and usually in the vehicle seat or.
  • the backrest provided air ducts and air guide layers pressed into the seat.
  • Such a device is known, for example, from the German patent DE 103 19 148 B3.
  • a blower sucks air through an air guide layer and air passages through openings located at the top and at the bottom edge on the back of the seat back.
  • German utility model DE 202 19 733 Ul a ventilation device for the seat of a vehicle seat is known.
  • This ventilation device is located below the seat cushion, a radial fan at a certain distance from the bottom of the seat cushion.
  • This radial fan sucks air between the underside of the seat cushion, usually a cushion shell, and an intake opening of the radial fan facing the latter and directs it via a bellows-type connection to an air duct system integrated in the seat cushion for distributing the air provided for ventilation.
  • This device suffers from the disadvantage that the free space below the vehicle seat is limited and therefore the arrangement of the radial fan is subject to certain restrictions.
  • such a vehicle seat can not be lowered completely to accommodate the needs of vehicle occupants of considerable height.
  • Such ventilation layers are usually made of a coarse-meshed spacer fabric, such as, for example, open foams, nonwovens, rubber hair o. like. which offers the air introduced a certain back pressure, which must be overcome by the blower device.
  • This counterpressure increases correspondingly when air is blown into the ventilation layer in a plurality of radial and optionally axial directions, as is the case in the previously described prior art.
  • either multiple fans must be used to provide the necessary fan power for the ventilation layer, or a relatively large, significant noise and vibration causing fan is necessary.
  • the core of the invention is therefore that in the ventilation layer at least one radial fan is integrated, wherein the radial fan is provided at one end of the ventilation layer such that the radial fan only the front side of this axially via a Heilansaug ⁇ réelle air sucked radially into the ventilation layer initiates. In other words, the radial fan blows the ventilation air only in one direction.
  • radial blower Due to the fact that the radial fan only blows radially in one direction, a much higher pressure build-up can be achieved. As a result, smaller blowers or fewer fans can be used for their dimensions. As a rule, a single radial fan is sufficient to achieve the necessary ventilation comfort. The radial blower also stands out due to the advantage that it occupies less space and works very low vibration.
  • the ventilation layer has at least one air outlet opening.
  • the air intake opening for the at least one radial fan is located on the same side as the air outlet opening, while in another embodiment, this air intake opening is arranged on the opposite side.
  • the height of the housing of the radial fan is at least as high as the height of the ventilation layer, but preferably smaller than this. As a result, the radial fan can be better integrated into the ventilation layer.
  • a plurality of radial fans are arranged parallel to each other at the front end of a ventilation layer. This makes it possible to build up a uniform, essentially approximately laminar flow, which is conducted uniformly through the ventilation layer, which results in better temperature and moisture removal from the seat cushion.
  • Fig. 1 schematically shows a cross-sectional view through a
  • FIG. 2 schematically in plan view and in cross section a second embodiment according to the invention.
  • the cross section is shown by a seat cushion 1 of a vehicle seat.
  • the structure shown in Figure 1 can be used equally for the backrest of such a vehicle seat.
  • the seat cushion 1 consists of an upper seat 2, which is covered by a seat cover 3. Below the seat cover 3 is a perforated foam insert 4, if necessary. with an integrated seat heating.
  • This foam insert 4 opposite a foam pad 5 is provided, which is supported on a spring core or a sheet metal shell 6 of the vehicle seat.
  • a ventilation layer 7 is provided, which is constructed from a coarse spacer fabric 8, for example rubber hair.
  • a radial fan 9 is embedded.
  • This radial fan 9 sucks through a HeilanSaugö réelle 10 ventilation air and passes them through the ventilation layer 7 until the air can leave the ventilation layer 7 again via an air outlet opening 11, as is exemplified by the flow arrows.
  • FIG. 2 shows by way of example a second exemplary embodiment according to the invention.
  • the ventilation layer 7 At the front end of the ventilation layer 7, two radial blowers 9 are arranged parallel to each other. As can be seen by way of example from the flow arrows, the bubbles blow Radial fan 9, the ventilation air in parallel and almost laminar through the ventilation layer 7. This causes a much more effective removal of temperature and humidity, wherein air turbulence by blowing out only in one direction are largely reduced.
  • the ventilation layer 7 in this embodiment has two air outlet openings 11.
