Problems solved by technology

[0014] However, although the conventional linear heating element 104 can increase the tensile strength of the linear heating element, it is not strong enough for bending due to repeated loads such as a load when seated.
That is to say, the crossing position between the core wire 103 and the conductor 102 formed by steel wires such as piano wire and stainless steel wire will be worn due to friction, causing the conductor 102 to break, and the durability of the linear heating element 104 cannot be fully improved.
[0015] In addition, although the linear heating element 106 can alleviate the occurrence of disconnection caused by the above-mentioned wear and tear, it is very difficult to form the conductors 104 into a braided shape around the bundled core wire 107 from a production point of view.

Embodiment 1

[0042] figure 1 It is a perspective view of a planar heating element (heating element) of the present invention, which is formed by fixing a linear heating element to a base fabric made of heat-sealable material in a predetermined wiring pattern. exist figure 1 Among them, the linear heating element 2 is fixed on the base fabric 3 made of heat-sealing material in a predetermined pattern by an adhesive 7 to form a planar heating element 1 .

[0043] below, through figure 2A method of manufacturing a seat with a heating device using the planar heating element 1 of this embodiment will be explained. Such as figure 2 As shown, the skin material 14 includes: a skin 14c made of leather, cloth, etc., a surface cushion 14b made of foamed urethane, a cover material 14a made of polyethylene film or woven cloth coated with impregnation prevention materials. After the planar heating element 1 is fixed on the above-mentioned cover material 14a, the seat of the skin 14 is placed in ...

Embodiment 2

[0049] image 3 It is a sectional view of the planar heating element of the second embodiment. Such as image 3 As shown in , the linear heating element 2 is fixed on the base fabric 3 by sewing. Generally, the method of arranging the linear heating element 2 on the base fabric 3 is to use an adhesive. However, if an adhesive is used, the heat-sealing material constituting the base fabric 3 will melt under the action of the adhesive, and the fixing strength around the linear heating element 2 may decrease. In such a case, by fixing the linear heating element to the base fabric 3 by sewing, it is possible to avoid adverse effects of the adhesive on the heat-sealed material. image 3 A side view of the linear heating element 2 fixed by sewing is shown, and the linear heating element 2 is fixed on the base fabric 3 made of heat-sealing material by the upper thread 4 and the lower thread 5 .

[0050] In addition, if at least one of the upper thread 4 or the bottom thread 5 for...

Embodiment 3

[0054] Figure 4 It is a schematic diagram of a linear heating element with a heat-welding layer on its periphery. Figure 4 Among them, in the linear heating element 9 of this embodiment, the heat-sealing layer 11 is provided on the periphery of the heating element 10 . As the thermally welded layer 11 melts and solidifies when the planar heating element is thermally welded to the skin, the strength of fixing the linear heating element to the skin can be increased.

[0055] In addition, it is preferable to use materials such as polyester, nylon, polyolefin, and polyamide as the material constituting the heat-sealing layer 11, but these are not restrictive.

[0056] In addition, in the description of this embodiment, the method of fixing the linear heating element on the base cloth adopts the method of using adhesive and sewing, but the method of fixing the linear heating element on the base cloth is of course It is not limited to these.

Abstract

A heating element used for a heated seat assembly of the present invention comprises a base material made of hotmelt material, and a linear heater disposed at a predetermined pattern on the base material. The linear heater is fixed by adhesion or sewing onto the base material. In one example of the present invention, the linear heater is characterized in that a plurality of conductors and threads are braided into the linear heater. In another example, a number of threads comprising the linear heater is at least the same with a number of conductors. According to the heating element of the present invention and the method of manufacturing the heated seat assembly according to the present invention, a heated seat assembly with excellent seating comfort and even seat temperature can be obtained, and a durability of the heating element improves.

Description

technical field [0001] The invention relates to a seat with a heating device used in various vehicles such as airplanes, automobiles and trains and a manufacturing method thereof. Background technique [0002] Existing seats with heating function are generally as Figure 12 As shown in , that is, between the skin 114 of the seat 112 and the main seat cushion 115, a planar heating element 113 used as a heating element is housed. A kind of method of manufacturing such seat is, at first with double-sided adhesive tape etc. the planar heating element is bonded / fixed on the skin 114, then skin 114 is inserted in the mould, injects urethane stock solution and makes It foams / hardens so that the skin and main seat cushion form a single piece. [0003] Among the existing planar heating elements used in the above manufacturing method, there is a Figure 13 , 14 On the base cloth that cloths such as non-woven fabric shown in and urethane surface cloth constitute, sew up linear heati...
