Abstract
Abstract The car seat heating device, which in particular can be fitted subsequently, comprises a thin, electrically insulating, three-dimensionally resilient carrier material (4) permeable to air and humidity. To the carrier material there is applied a resilient surface heating element (2) with a latticed structure comprising free spaces (5).
The surface heating element (2) has a parallel conductor form, and three-dimensional deformability. To the surface heating element (2) is applied an adhesive film (3) permeable to air and humidity, which bonds the surface heating element to the carrier material (4) through the free spaces (5) in the latticed structure. To the adhesive film (3) there is applied a protective foil (1), which is separable therefrom. The adhesive strength of the adhesive film (3) is suitable for adhesion to the back of a car seat cover.

Description
2~72~2 CAR SEAT ~EATING DEVICE WHICH CAN
BE FITTED SUBSEQUENTLY
The invention relates to a car seat heating device, and in particular to a car seat heating device which can be fitted subsequently.
As is known, the seats of an increasing n~mber of cars and commercial vehicles are being e~uipped with car electric seat heating devices, either as a production line fitting or as a special accessory ex works. Subse~uent installation of such seat heating in the original design is only possible at great expense, or not at all. For this reason a series of car seat heating devices has been developed which can be f itted subsequently and which act as s~perimposed seat heaters similar to electric heated cushions, attached by means of tapes to the surface of the seat, or as loose seat covers with integrated seat heating, produced to fit the individual seats of the various vehicles, and fitted over the seat and back.
These known forms of car seat heaters fitted subsequently use relatively thick insulated stranded heating conductors made of copper, the mechanical strength of which is relatively low. Since car . .
2~72~
seat heaters develop folds if they are not expertly fitted or if the heating elements used do not fit perfectly, kinks form in the stranded copper conductors. Yehicle and seat vibrations give rise to high flexural stresses, which in the kink area lead to breakage of the Individual strands of the conductor after only a short time. This results in local o~erheating, described as a hot spot, which can cause fires. In order to c~unteract this danger, the heating mats have a very thick structure, in order to prevent the formation of folds. In addition stretching frames made of spring steel wires are used. Although in thick heating mats fold formation no longer occurs, the heating up times are very lon~. They also alter and impair the seating comfort and seatin~
climate.
Contrary to the market requirements for very varied forms, colours and materials, for economic reasons only a few variants of seat covers with integrated seat heating are available.
The o~ject on which the invention is based therefore consists in providing a car seat heating device, in particular a car seat heating device which can be fitted subsequently, which can be manufactured as a mass-produced article and is - 2~72~2 suitable for all known car seats, without any safety risks or disadvantages concerning com~ort.
According to the invention this object is achieved by means of a car seat heating device, and in particular by a car seat heating device which can be fitted subse~uently, having a thin, electrically insulated, three-dimensionally resilient carrier material permeable to air and humidity, a flat resilient heating element applied to the carrier material, with a latticed structure comprising free spaces, having a parallel conductor arrangement with three-dlmensional deformability, a resilient adhesive film permeable to air and humidity, which is applied to the heating element and bonds the latter by adhesion to the carrier material through the free spaces in the latticed structure, and having a protective foil appliet to, and separable from the adhesive film, wherein the adhesive strength of the adhesive film is designed for attachment to the back of a car seat cover.
The car seat heater according to the invention can be produced such that it is very thin, since the formation of folds does not constitute any safety risk, owing to the ~ka~ heating element used, which is the subject matter of patent applications ., ~ -2~72~-2 P 40 20 580.~ and P 41 01 290.9. Owing to the thin structure, the effect of heating can be felt very quickly. The seating comfort and seating climate are only slightly impaired.
Advantageously the adhesive film is a double-sided adhesive foil. Permanent adhesives of this type, having a high level of contact adhesion, are available commercially.
The carrier material is preferably a thin upholstery material ~eg foam material) backed by a textile flat shap~d article.
The car ~eat heater is particularly suitable for adhesive attachment to the ~ack of a loose seat cover, which is produced according to the required form, colour and size, and to which the car seat heater can be simply and firmly attached, after the protective foil has been removed.
The car seat heater which can be fitted subsequently can comprise a carrier material which is continuous for the seat and back, wherein El~L
heating elements are provided in the seat and back areas, whereas the area therebetween is an unheated surface, suitable for accommodation of 2~7~2 the electrical connections and directinq them later~lly to the outside.
The invention is explained in greater detail by means of a drawing, showing a cross-section of an em~odiment of the car sea~ heater.
The car seat heater s~ in the drawing which ~ be fitt~d subsequently comprises a thin strip-like carrier material 4 made of textile-reinforced foam material. To this carrier material there is SV~
applied a ~ heating element 2 with a latticed structuro comprising free spaces 5 and which can be deformed three-dimensio~ally. A resilient synthetic resin adhesive film 3 which is Dermeahle to air and humidity , and is covered on one side with the protective fcil, is pressed onto the ~h~r heating element 2. The synthetic resin adhesive film 3 passes through the free spaces 5 in the mesh-type structure of the ~ heating element 2 ~P,~C~
and bonds the ~Pr heating element 2 to the carrier material 4. The protective foil 1 applied to this structure for the pur?ose of storage and dispatch, a~d which adheres to the adhesive film 3, can easily be removed therefrom.
.
For installation of the car seat heater, the protective foil 1 is remLved. The car seat heater is .
' 2~72~2 then ~onded ~y means of the adhesive film 3 to the inner side of a car seat cover or to the back of a loose seat cover, wherein the adhesive strength is sufficient for non-slip attachment.
