In addition, as shown in FIGS. 14 and 15, while cutting the sheet heating sheet 100 in the same shape as the outline of the user area, a circular opening corresponding to the ventilation hole of the vehicle seat is formed in the middle of the cotton fabric 10. can be formed In this case, the conductive yarn 30 of the warp may electrically connect the conductive yarn of the weft yarn cut off by the opening with the conductive yarn of the other weft yarns on the upper and lower sides thereof so that all the conductive yarns of the weft yarn operate as a heating wire.

As described above, the present invention can manufacture a low-power planar heating sheet and easily attach it to the vehicle seat cover by means of tape, adhesive, sewing, etc., thereby easily manufacturing the vehicle seat cover, and manufacturing the vehicle There is an advantage of obtaining excellent energy efficiency from the seat cover.

In addition, regardless of the type of vehicle or vehicle seat cover, it can be easily applied to various types of vehicle seat covers simply by manufacturing a basic planar heating seat and cutting it to fit the vehicle seat cover, greatly improving the convenience of the manufacturer's user. There are advantages to doing it.

On the other hand, in the above-described embodiments, the configuration of the planar heating sheet for the case of having two user regions divided in the vertical direction by the middle opening in the weft direction has been mainly described, but the present invention is not limited to such a configuration, and the present invention is not limited to such a configuration. It is self-evident that the flat invention sheet of the present invention can be easily applied even when it has two user areas (in the case of climbing design) disposed on the left and right based on the middle line of the inclination direction of the user area.

16 and 17 are partially enlarged perspective views of two forms for explaining a planar heating sheet according to another embodiment of the present invention.

Referring to FIG. 16, the planar heating sheet according to the present embodiment has a conductive yarn 30 integrally woven into a planar fabric 10 including a fiber yarn, and carbon fiber (hatched) inserted into the weft and warp yarns. It is woven with a low-power planar heating element of a parallel structure using the weft and warp yarns of the part. The woven planar heating element is integrally disposed on the cover. In the case of the planar heating sheet having such a structure, it provides improved manufacturing convenience.

In the process of arranging the planar heating element on the sheet-like cover, the planar heating element is attached to the seat form 220 inside the seat cover body. Through the vent hole (vent hole, 70) is formed. At this time, a part of the planar heating element attached to the seat form is removed by the vent hole (70).

As such, the planar heating sheet according to the present embodiment has a small disadvantage in that the heater line of the heating element is lost by the vent hole 70 in addition to various advantages, thereby generating a thermal cavity.

Accordingly, another embodiment provides an additionally improved planar heating sheet so that the heater line is lost and does not generate uniform heat in the entire area of the planar heating element, or unnecessary loss occurs in terms of the manufacturing process.

Referring to Figure 17, the planar heating sheet according to this embodiment is a sheet cover body 200, that is, after attaching a planar heating element made of a planar fabric 10 to which the conductive yarn 30 is bonded to the seat cover body 200, that is, to the bottom of the seat cover, not the seat form. , it is possible to manufacture an integrated automobile seat by fixing the seat form (refer to 220 in FIG. 16) and the seat cover body 200.

At this time, in order to secure ventilation without the process of forming a vent hole, a space through which air can pass through the fabric is formed by adjusting the weft density of the weft and warp yarns of the fabric when manufacturing the planar heating element. do.

The control of the density of the fabric may be formed by controlling the thickness of at least a portion of the weft or warp yarns, or controlling the elasticity of the fabric in which several yarns are intertwined with each other according to a certain rule. Elasticity can be increased when there is less twist compared to warp or when thick thread or decorative yarn is used.

In this way, the cotton heating sheet controls the density of the cotton textile by controlling the elasticity of the cotton textile or changing the thickness of the weft or warp yarns in the process of weaving or knitting the cotton textile, so that the cotton textile itself can be manufactured to have breathability.

According to this embodiment, since the planar heating element is attached to the seat cover body 200, that is, at the bottom of the seat cover, not the seat foam, a vent hole is not formed in the planar heating element, so that the heater line of the planar heating element is not lost. . Therefore, it is possible to prevent a thermal void phenomenon due to the loss of the heater line of the planar heating element, and thereby it is possible to transmit heat very uniformly and stably over the entire area of the planar heating element. In addition, since there is no planar heating element part that is lost due to the formation of the vent hole, an improved effect can be expected in terms of manufacturing efficiency. And in the case of the process of ensuring air permeability of the planar heating element through the control of the fabric density of this embodiment, only the density of the fabric, that is, the fiber yarn 10, which is the substrate of the planar heating element, is adjusted and the heater line is maintained as it is to keep the heating properties constant while maintaining the air permeability has the effect of securing

As such, according to the present embodiment, by using the improved process, it is possible to manufacture a car seat in which ventilation is ensured without a vent hole while maintaining uniform heating characteristics for the entire area of the planar heating element.

Although the above has been described with reference to preferred embodiments of the present invention, it is understood that those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims. you will understand
