Problems solved by technology

[0004] However, in the conventional structure, it takes time for the warm water supplied to the warm water piping 6 to rise in temperature, and in winter, the heating may be insufficient immediately after riding the car.
In addition, regarding the arrangement of the piping 6 for hot water, it is necessary to install the piping in each part of the vehicle, which takes man-hours.
In addition, in the conventional structure, the seat cannot be tilted unless the radiant panel is divided into the upper radiant panel 3 and the lower radiant panel 5
For example, if the upper radiant panel 3 and the lower radiant panel 5 are integrated, the panels may break and water may leak when the seat is tilted.

Abstract

A seat heating device is provided with: a cover which covers the seat from the rear side of the backrest of the seat to the bottom surface of the sitting section of the seat,and a flexible heat generation section which is provided to the rear surface of the cover at a position between the cover and the seat. The configuration enables a single heater section to heat by radiation the lower legs and feet of a rear seat occupant.

Description

technical field [0001] The present invention relates to a seat heating device arranged on a seat to heat the feet of, for example, a passenger sitting on a rear seat of a vehicle. Background technique [0002] In recent years, energy-saving vehicles such as low-fuel-consumption vehicles, hybrid vehicles, and electric vehicles have become increasingly popular. In order to spend comfortably in the car even in winter, a vehicle that can perform energy-saving heating is desired. As a device responding to such a demand, a device is disclosed that supplies engine cooling water of a vehicle to a radiation panel provided on the back of a backrest of a front seat (for example, refer to Patent Document 1). Next, use Figure 7 A seat heating device using engine cooling water of a vehicle will be described. [0003] Figure 7 It is a cross-sectional view of a conventional seat heater. Such as Figure 7 As shown, the existing seat heating device is composed of an upper radiation panel ...
