본 발명은 면상발열장치에 관한 것이다. 보다 상세하게는 자동차 내장재에 적용할 수 있는 플렉시블한 면상발열장치에 관한 것이다. The present invention relates to a surface heating apparatus. More particularly, the present invention relates to a flexible surface heating apparatus applicable to an automobile interior material.

자동차의 내장재는 도어트림, 범퍼, 콘솔, 시트 등 다양한 제품들로 구성된다.The interior of the car consists of various products such as door trim, bumper, console and seat.

종래 자동차는 운송수단의 일종으로만 여겨졌으며, 자동차 내장재에 대한 미려감이나 감촉 등과, 다양한 기능(예를 들면, 발열기능 등)에 대해서는 크게 고려하지 않았다. Conventionally, automobiles are regarded only as a kind of transportation means, and they do not consider much about the sense of touch and feel of automobile interior materials and various functions (for example, heat generation function).

그러나, 현재 자동차는 운송수단으로서의 역할을 넘어서 사용자의 개성을 표현하는 물품으로 여겨지고 있어 자동차 내장재에 대한 개선에 많은 연구를 진행하고 있는 추세에 있다.However, the automobile is considered to be a product expressing the personality of the user beyond the role of the vehicle as a means of transportation.

이러한 추세 속에서 자동차의 내장재는 점차 사용자가 원하는 기능과 감성품질에 만족할 정도로 개선되고 있는데, 특히 자동차의 내장재 중 도어 트림은 자동차 실내 미관 향상은 물론 승객의 안락하고 쾌적한 운전공간을 마련해주고 주행중 발생할 수 있는 외부충격으로부터 운전자와 승객을 보호하며 각종 수납공간, 안전장구, 전자장비 등을 설치하는 공간이며, 사용자가 팔이나 다리가 인접할 수 있어서 발열기능을 추가할 경우 사용자의 만족감을 보다 향상시킬 수 있게 된다.In this trend, the interior materials of automobiles are gradually improved to satisfy user's desired function and sensitivity quality. In particular, door trim of interior materials of automobiles not only improves the interior appearance of automobiles but also provides comfortable and comfortable driving space for passengers, It protects the driver and passengers from the external impact and installs various storage spaces, safety gears, electronic equipments, etc., and the user can be adjacent to the arms or legs, .
