Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a seat for a heating vehicle capable of electric heating.

(Prior Art) Conventionally, heating of seats includes one using a room heater that uses exhaust heat of an engine and one that uses an alloy heating wire such as a nichrome wire in the seat.

(Problems to be solved by the invention) However, such heating means, for example, a room heater is suitable for heating not only the seat but also the entire room, but large equipment is required to heat a small small portion. It is too large and the energy loss is large and inappropriate.

On the other hand, the alloy heating wire is suitable for heating a small part, but it has the drawback that the heating metal wire itself is fragile and easily breaks due to bending fatigue, and there is a high possibility that the wire will break when hooked on the sewing machine during sewing. Yes, it was extremely susceptible to product design restrictions.

In view of such conventional drawbacks, the present invention can sufficiently withstand a long-term harsh use of a seat by using a heater structure made of a specific flexible material that is highly flexible and has excellent bending fatigue resistance. It was possible to provide a heated seat.

The seat of the present invention is not restricted by the assembly process, design, etc., has a wide degree of freedom in its application, and evenly generates heat over the entire setting area. It is extremely reliable, durable, and practical, demonstrating that it does not stop.

(Means for Solving Problems) The present invention adopts the following configuration in order to achieve the above object. That is, (1) a sheet heater having a parallel wiring structure composed of an electrode made of a metal conductive wire and an organic linear heating element yarn is incorporated in at least a part of the seat surface and the back surface of the seat. Heating seats to be seated.

(2) The heating according to claim (1), wherein the organic linear heating element yarn has a structure in which a flexible synthetic resin containing conductive particles dispersedly covers the core yarn. Seat seat.

(3) The heating seat according to claim (2), wherein the conductive particles are at least one selected from carbon black and metal powder.

(4) The heating according to claim (1), wherein the planar heater is configured by using an organic linear heating element yarn as a weft component and a metal conductive wire as a warp component. The seat is a seat.

The present invention will be described with reference to the drawings.

FIG. 1 is a perspective view illustrating a heating seat according to the present invention. The seat of the present invention comprises a seat surface 1 and a back surface 2. The sheet heater 3 is set on a part of such a seat, for example, the central portion of the seat surface 1 and / or the central portion of the back surface 2. The planar heater 3 is characterized by having a parallel wiring structure as shown in FIG. In this example, the metal conductive wire 4 is used for the warp and the organic linear heating element yarn 5 is used for the weft, and the metal conductive wire 4 has a function of functioning as an electrode. This conductive wire 4
The terminal is provided with a lead wire, and electricity is supplied through the lead wire.

The electrode composed of such a metal conductive wire 4 is usually composed of a thin wire of copper or other conductive metal, metal plating, or a variety of metal-coated fiber threads such as sputtered flat fibers. In particular, metal-coated fiber yarns are suitable for the present invention because they have excellent flexibility. Although one metal conductive wire 4 can exhibit the electrode function, it is preferable to use a plurality of metal conductive wires 4 from the viewpoint of durability and safety. The heating element yarn 5 is wired in parallel. Such a conductive wire 4 which is rust-proofed and which is formed into a highly flexible twisted yarn is a preferred embodiment of the present invention.

Since the organic linear heating element yarn 5 is an organic fiber, it does not damage the sewing machine needle during sewing. Therefore, unlike the conventional nichrome wire sheet, the heating seat of the present invention has seams in the vertical and horizontal directions. It has an epoch-making feature that it can be formed.

FIG. 3 illustrates the cross-sectional structure of the organic linear heating element yarn 5 of the present invention.

The organic linear heating element yarn 5 has a structure in which a flexible synthetic resin 7 containing conductive particles 6 dispersed therein covers a core yarn 8.

As the conductive particles 6, at least one selected from carbon black and metal powder is applied. The particles are not particularly limited as long as they are in a fine powder state that does not cause a problem in kneading properties and coating properties, but particles having a particle size of about 20 to 40 mμ are preferably applied. It is a particularly preferred embodiment of the present invention to add a substance having an effect of increasing the emissivity of far infrared rays, such as ceramics powder, to the heat generating composition, in the conductive particles 6. Of course, such a substance, for example, a ceramic powder dispersion layer having a structure in which a heating layer made of the conductive particles is coated also provides an excellent heating element. Furthermore, when the ceramic powder dispersion layer is provided on the surface of the heating seat sheet of the present invention, it is possible to provide a sheet that exhibits an excellent thermal effect without electric shock.

The flexible synthetic resin 7 that supports the conductive particles 6 is not limited as long as it is flexible and has relatively little thermal deterioration and binder properties (adhesiveness). Resins such as acrylic and polybutyral can be used.

In the present invention, the amount of the conductive particles mixed with the flexible synthetic resin does not have to be limited as long as sufficient heat is generated as a heating element, and the electrical resistance value is usually about 13 kΩ / m.
Properly adjusted and mixed, the seat provides a preferable heat value. However, the amount of heat generated is usually changed depending on the place, the wiring method, the amount of electricity, etc. In that case, the electric resistance value is changed to about 1 to 100 kΩ / m.

The flexible synthetic resin 7 containing the conductive particles 6 dispersed therein is coated and carried on the surface of the core yarn 8. The core yarn 8 may be an ordinary organic fiber such as polyamide, polyester, polyolefin or polyacryl. Synthetic fibers such as. When expecting a temperature-fusing function as the core yarn 8, it is preferable to select a synthetic fiber having a definite melting point at a desired temperature.

The planar heater 3 of the present invention is, for example, 13k as described above.
It is also one of the features that it is composed of a material having a relatively high resistance value such as Ω / m. That is, it is possible to employ a parallel wiring structure that has not been considered for a low resistance material such as a nichrome wire heater, and it is possible to dramatically improve the durability and safety. Since the planar heater 3 of the present invention uses the one adjusted to have a high resistance value as described above, it is also characterized in that sufficient heating can be obtained by an ordinary small power source such as a dry battery or a storage battery. The resistance value can be further increased if necessary.

FIG. 2 shows an example in which the metal conductive wire 4 is used for the warp and the organic linear heating element yarn 5 is used for the weft. By adopting such a structure, uniform Joule heat is generated from the entire heater surface. In addition, even if one or several weft organic linear heating element yarns are cut, the heating function is not totally lost, and the total resistance increases due to the cutting, which further increases safety. It has the feature of increasing.

The organic linear heating element yarn 5 and the metal conductive wire 4 can be made into a cloth-like structure by using an ordinary loom, and have a flexible performance like an ordinary woven fabric.

In the heating seat of the present invention, the heat generation amount can be increased as the distance between the electrodes in which a plurality of electrodes are arranged is reduced and the density of the organic linear heating element yarns is increased (increased). . Therefore, the heat generation amount can be appropriately controlled by adjusting these requirements.

(Effect of the device) The heating seat according to the present invention has excellent properties such as flexibility and bending fatigue resistance, and further has excellent properties such as abrasion resistance, bending resistance, and mechanical strength. Because of this, the degree of freedom in product design is greatly expanded compared to conventional heaters, and it is epoch-making that sewing work can be done easily without fear of cutting problems such as sewing and quilting.

INDUSTRIAL APPLICABILITY According to the present invention, it is extremely effective for heating seats of vehicles such as automobiles, motorcycles, electric trains, trains, aircraft, ships, and even ferris wheels in amusement parks.
