In recent years, with the advancement of seat comfort system technology, heated and ventilated seats with air exchange function have become a new product that is gradually accepted by people. Through fan-driven air exchange between the seat surface and the interior of the seat surface, a better local environmental interface can be achieved on the surface of the seat occupant's body.

A common application of this type of seat heating and ventilation device is to set an air-guiding spacer body with a certain thickness and a breathable structure inside the seat cover as a space for the internal air to flow. On the top of the air guide spacer, that is, on the side close to the seat surface, an electric heating pad for the seat surface is arranged. The electric heating pad body can realize the direct heating and temperature raising transfer effect on the chair surface after being energized.

However, a prominent weakness of this type of heating and ventilation device is that the seat surface electric heating pad body is assembled on the upper part of the air-guiding spacer body. Because the heating pad is located above the air-guiding spacer layer, it often blocks the flow of air to the seat surface with pores. , affecting the air permeability of the seat surface, which is likely to cause dissatisfaction among seat users in summer. Simultaneously, because the heating pad is close to the seat surface, when the local heating temperature is out of control, the event of burning the skin of the seat user will also occur.

Therefore, how to solve the problem that the heating pad will partially block the flow of air to the seat surface and affect the air permeability of the seat surface, so that the air permeability and thermal performance of the seat surface in winter can be well realized is a technology that those skilled in the art need to solve at present. question.
