Abstract

The invention relates to a device (100) for conducting air in order to provide air conditioning for a body support device, particularly one in a vehicle seat. According to the invention, the device (100) is also provided with at least one adjustment device (7) for adjusting at least one contact area (20) of the body support device that comes into contact with a user.

Description

  • The present invention relates to a device for guiding air according to the preamble of claim 1. Devices according to the class are used, e.g., for air conditioning vehicle seats.
    • STATE OF THE ART
  • Air-conditioning devices for vehicle seats are known. Pneumatic seat adjusters for lumbar support and massage systems for seats are also known. Integrating both systems into a seat is problematic. If a seat adjuster is positioned under a seat cushion, large volumes must be moved in order to notice an effect at the seat surface. This leads to overdimensioned pumps and low adjustment speeds. Conversely, the air-conditioning function is impaired when the adjustment elements are positioned on the sitting surface.
    • OBJECT OF THE INVENTION
  • One object of the invention is a device with the features of claim 1. This has the advantage that through the integration of a seat adjuster into an air-conditioning device, mutual interference between the two systems is avoided.
  • Other advantageous constructions can be taken from the subordinate claims.
    • FIGURES
  • The following description deals with possibilities for configuration of the invention. These designs are to be understood as only examples, and reference is made to:
  • FIG. 1, top view of an air-conditioning device with adjuster
  • FIG. 2, longitudinal section through the arrangement of FIG. 1
    • DESCRIPTION OF THE INVENTION
  • A body support device is understood below to include, in particular, any furniture for sitting and/or resting and all devices offering support to a person while standing, sitting, or lying down in vehicles.
  • FIGS. 1 and 2 show a functional module according to the invention. A device 100 for guiding air for air conditioning a body support device has a carrier layer 1. This is manufactured from an air-permeable material. In the embodiment, it is formed at least partially by a non-woven material. It is designed for overlay on a foam core of a cushion, especially of a vehicle seat.
  • On the side of the carrier layer 1 facing a contact zone 20 and a user there are heating conductors 11 of an electrical heating element. They are arranged essentially over the entire surface of the carrier layer 1. They can be produced from metal and/or from electrically conductive plastics, e.g., carbon.
  • An air-guiding layer 2 is arranged on the side of the carrier layer 1 facing away from the contact surface 20. The air-guiding layer 2 can be formed, e.g., from a spacing fabric. In the present example, it is formed from a plurality of spirals extending longitudinally in the guide layer. It has a sufficient cross section of, e.g., one centimeter, to provide a sufficient amount of air to the contact surface 20. The dimensions of its basic surface are somewhat smaller than that of the carrier layer 1. It is therefore guaranteed that when the air-guiding layer 1 is inserted into a corresponding recess of a seat cushion, there is no detectable unevenness at the edges.
  • The air-guiding layer 2 is essentially completely covered by a wall 25. This is formed in the embodiment from a polyurethane film that is not permeable to air. The wall 25 essentially completely covers the air-guiding layer 2. It is connected—in the embodiment, adhered-to the carrier layer in its edge region.
  • The wall 25 has a recess connected to an air-feeding device 4. This air-feeding device 4 is formed in the present embodiment by a fan 14, which is fixed indirectly or directly to the air-guiding layer 2 and/or to the wall 25. It can also be formed, however, by a tube or a snorkel-like extension of the wall 25, which is connected, e.g., to a distant fan or an on-board air-conditioning system.
  • At least one adjusting device 7 is provided on the wall 25. This adjusting device 7 has a volume body 27 whose volume is variable. In the present example, the volume body 27 is formed from a bladder 17. This bladder 17 is preferably formed from material that is not permeable to air. In the present embodiment, the bladder is also formed from polyurethane film. A part of the bladder wall 30 is here formed by the wall 25 of the air-guiding layer 2.
  • The volume body 27 preferably has an elongated construction and runs perpendicular to the expected position of the spinal column of a user. It is preferably constructed thicker at its ends. In the area of its center, in the vicinity of the spinal column, it has a narrower construction. The volume body 27 is connected to a fluid supply device and/or an outlet valve via a fluid line 8.
  • For the shown case that several volume bodies 27 are provided, a plurality of fluid lines 8 is also required if the volume body 27 is to be individually adjustable. Because the fan 14 also requires an electric supply line 5, it is preferable to guide the fluid lines 8 and the supply line 5 within the air-guiding layer 2. In order to not interfere with the air-distributing function of the air-guiding layer 2, it is preferable to guide it along the edge of the air-guiding layer 2.
  • During operation, an air stream 9 is blown into the air-guiding layer 2 via the fan 14 for air conditioning. There it is distributed along the carrier layer 1, and is then blown out through this layer and through the heating element to the user.
  • For adjusting the seat contours according to the desires of the user and/or for massaging, the bladders 17 are filled via the fluid lines 8 with a corresponding amount of fluid. In this way, the bladder 17 expands or contracts accordingly. Thus, the contact zone 20 is positioned or moved accordingly.
