Definitions
- the present invention relates to a planar heating element used for a seat or the like, and more particularly to a planar heating element mounted on an automobile seat.
- a sheet heating element conventionally attached to this type of seat requires flexibility of the base material in order to improve the seating comfort of the seat, and also requires hardness of the base material. .
- the heating element which is the heater wire force
- the base material is directly subjected to the load stress at the time of sitting, so that the hardness of the base material is also necessary to prevent the heater wire from being disconnected.
- there is one composed of a base material having a raised surface on the surface opposite to the heating element holding surface see, for example, Patent Document 1).
- FIG. 6 shows a conventional planar heating element described in the patent document.
- the planar heating element 1 is composed of a base material 2 with one side raised, a heater wire 4 that is sewn and held on a surface opposite to the raised surface 3 of the base material 2, and a heater wire. It is composed of sutures 5 for holding 4 by sewing.
- FIG. 7 shows a conventional planar heating element described in the above publication.
- the planar heating element 6 is composed of a base material 9 formed integrally by entanglement of fibers of a nonwoven fabric 8 with a base fabric 7.

There is a problem that it is difficult to achieve both the flexibility of the material 2 and the hardness of the base material 2 to prevent the heater wire 4 from being disconnected when the load stress at the time of sitting is large. And then
- the base material 7 is integrally formed by entwining the fibers of the non-woven fabric 8 with the base fabric 7, so that the base 9 is formed by repetition of load stress at the time of sitting.
- the fibers 7 and 9 are gradually untangled, and the hardness of the substrate 9 becomes softer and stronger.
- the fibers of the base fabric 7 and the nonwoven 8 that form the substrate 9 are used. As a result, the delamination between the base fabric 7 and the non-woven fabric 8 occurred, and the hardness of the base material 9 for preventing the heater wire 4 from being disconnected could not be maintained.
- the present invention solves the above-described conventional problems, and has flexibility for improving the seating comfort of the seat, reduces the load stress at the time of sitting on the heating element, and the heating element is disconnected.
