Abstract

The present invention relates to a heating device (1) for vehicle seats with a cushion support (3) which has at least one recess (7) on its upper side (15) and with a heating element (5) which is located on the upper side (15) of the cushion support (3) is provided. DOLLAR A It is contemplated that the heating element (5) has a Heiztextil.

Description

  • The The present invention relates to a heater for vehicle seats with a cushion pad, which on its upper side at least one Well, and with a heating element, which at the top the cushion pad is provided.
  • Known are cushions for Vehicle seats, which are mounted on a seat core and of covered a seat cover. The cushions are with parallel mutually extending groove-shaped Wells provided. In these recesses run in the finished Vehicle seat seams, which connect the seat cover with the cushion pad.
  • Around To provide such cushions with a heater is first the seat cover or an additional one backing textile Sewn with the cushion pad. This will cause hoses, so-called "whistles", formed between the seams. In each of these tubes will follow a Heizleiterschleife fed. It is required first the hoses too sew, to avoid injury to the heating conductors during sewing. Otherwise, would because of the series connection of Heizleiterschleifen a total failure of Heating threaten. This process is extremely time consuming and awkward.
  • From the DE 42 33 118 A1 For example, a heating textile is known, which consists of a fabric formed of carbon fibers, in which flexible contact wires are incorporated, which are electrodes. The heating textile is arranged in the seat surface of a vehicle seat. An indication of the way in which the Heiztextil is attached, this document is not included.
  • The DE 41 22 363 C1 describes a seat heating, which has a thin electrically insulating three-dimensional elastic, air and moisture-permeable carrier material. On the carrier material, an elastic surface heating element is applied with freestanding net-like structure and parallel Heizleiteranordnung with three-dimensional deformability. On the surface heating element, an air-permeable and moisture-permeable elastic adhesive film is applied, which connects the surface heating element with the carrier material by the free spaces in the net-like structure by sticking. On the adhesive film, a detachable protective film is applied. The adhesive force of the adhesive film is designed for adhesive attachment to the back of an automobile cover. An attachment of a heating element on a cushion pad, which has recesses on its upper side, by means of the adhesive film, would cause the heating element can not penetrate into the recesses, whereby the sewing of the seat cover would be difficult to the cushion pad and greatly impaired the visual appearance becomes.
  • Of the Invention has for its object to provide a heating device, securely attached to a cushion pad with little effort can be on which a seat cover is sewn on without affecting its function and the external appearance of the vehicle seat affected becomes.
  • These The object is achieved by a heating device having the features of the patent claim 1 solved.
  • There the heating element comprises a Heiztextil, in the attachment the seat cover itself a whole series of pinholes the electric current flow not negatively affected by the Heiztextil. In addition, will on the surface the heat conductor visible bumps by emerging heating conductor avoided. The appearance is also due to the bonding Flanks of the depression optimized. The use of the heat-activated Adhesive allows even on uneven surfaces and on the flanks of the Wells a reliable Bonding. It is possible, the heating element first to position as desired and only afterwards perform the bonding.
  • If the heating textile is reinforced by a non-electrically conductive carrier textile, allows this make the electrically conductive heating textile very filigree. Thereby let yourself improve the heating effect.
  • If the heating textile on the carrier textile is applied, this simplifies the manufacture and increases the stability of the heater.
  • characters
  • The The following description deals with possibilities for the design the invention. These designs are only to be understood as examples and are made with reference to:
  • 1 Top view of a cushion pad with recesses
  • 2 Cross section through a heater after 1 along the wells
  • 3 Partial cross section through the heater according to 1 across the wells
  • description the invention
  • 1 shows a heater 1 with a rectangular cushion pad 3 , The cushion pad 3 indicates at its top 15 in the longitudinal direction of the cushion pad 3 mutually parallel, groove-shaped depressions 7 on. Between the grooves run increased areas 13 , the so-called "whistles".
  • Under The upper side in this description is the side of the cushion pad understood, which points in the installed state to the seat occupant.
  • At opposite edge areas of the cushion pad 3 are two electrodes 11 provided for. These electrodes extend over the entire length of the cushion pad 3 and run parallel to the longitudinal direction of the cushion pad 3 ,
  • On cushions pad 3 is a flat heating element 5 applied. The heating element 5 covers the entire top 15 the cushion pad 3 and is electrically conductive with the electrodes 11 connected. The heating element 5 is also at the bottom of the wells 7 and their flanks 8th attached.
  • The heating element 5 may be constructed of one or more materials and one or more layers.
  • In its simplest, here presented form exists only from an electrically conductive Heating textile, preferably made of graphite fibers.
  • Under Textile is understood in this description of any planar structure. This Term includes here woven and knitted fabrics as well as foils.
  • To connect the heating element 5 with the cushion pad 3 For example, a heat-activatable adhesive is used. By "heat-activatable" is meant that the adhesive passes at least once into a stickable state at a temperature which is above the usual operating temperatures of a vehicle seat heater and produces a firm bond on cooling. The activation temperature is preferably above 60 ° C., in particular above 90 ° C.
  • In operation, current flows from a current source, not shown, over the entire length of the one electrode 15 in the heating element 5 , It flows through this to produce the desired heating and flows over the other electrode 15 back to the power source.
  • The heating element 5 also be constructed in two or more layers. Preferably, an electrically non-conductive carrier layer, for example of a textile plastic material, is then provided. The heating textile can then be attached to this carrier layer. The heating textile is preferably applied to the carrier layer. However, it can also be glued on.
