In general, indoor and outdoor stadiums where various sports such as soccer, baseball, American football, and winter sports are held are equipped with plastic chairs. In this case, they are mostly installed outdoors so that people can sit down to watch sports or performances. It is used for a long period of time and has to be sitting for a long time for about 2 hours or more, so it is inevitable to be sensitive to the external climate environment such as external temperature, humidity, and cold. This is especially true in stadium environments where sub-zero temperatures, such as the Winter Olympics, must be maintained.

Therefore, when the user has to sit for a long time on the cold seat because the outside temperature is low, in the case of a person with a hemorrhoid disease, it is difficult to watch a comfortable game due to physical discomfort, and the general public may be exposed to common diseases such as cold. However, the elderly and children are inevitably more sensitive to this stadium environment.

To this end, in the related art, a heating element was separately provided and placed on the upper part of the seat, and a thin cushion or cloth was covered with the upper part of the heating element, or a separate heating cushion had to be used. For the 2018 Winter Olympics conference seats, an outdoor heating seat cover that generates heat at an appropriate temperature using a carbon heating element was also used.

However, this was temporarily used by placing a separate heating member on the upper part of the existing chair seat, but not a form in which a heating member was loaded inside the chair, and a rectangular heating bench for bus stops developed for a similar purpose of preventing cold Currently, many are installed.

For example, in Korean Patent Registration No. 10-1390655, it is a bench-type rectangular chair structure that is installed outdoors such as a bus stop, a railway station, or a park and has a seating groove at a certain depth on the upper surface of the seating table. A form in which a planar heating element, a heating plate, and a cover plate are sequentially stacked is disclosed.

However, in this case, since many users use it at the same time, it is a structure in which a planar heating element, a thermal insulation pad, and a cover plate are sequentially installed in the entire area of the upper surface of a rectangular-shaped chair. There is a difference in terms of the side, and due to the nature of the chair being exposed to the outside when the cover plate is installed, there is a possibility that problems such as rainwater flowing down between the minute gaps formed near the rim of the seating groove, or water droplets are generated in an environment with high humidity. .

Of course, in order to prevent the inflow of rainwater, etc., it is possible to prevent the inflow of rainwater into the main body by forming the seat cover by bending downward at the outer corners and screwing the side in a structure that covers the entire upper surface of the main body of the seat. In this case, there is a problem in obtaining the efficient heating effect desired by the user because the cost of the sheet cover, which is a relatively expensive material with strong thermal conductivity, is incurred, and local heating required in a customized single-person seat is impossible due to a relatively large heating area. .

In addition, Utility Model Publication No. 20-2014-0005307 discloses a plastic chair having a heater function, and even in this case, it is similar in that the chair molding material is plastic, but the cover part covers the entire surface. The problem is inherent as it is, and it is difficult to block the inflow of rainwater penetrating through the gap generated when the cover part and the seat part are combined, and thus there is a lack of moisture-proof efficiency.
