Abstract

PURPOSE: To improve comfortableness in use by forming a first apparatus body and a second apparatus body different in temperature to make the warmness of heating equal between a seat part and a back part even when a larger load works on the seat part. CONSTITUTION: A heater 1 includes a first apparatus body 10 and a second apparatus body which have roughly flat heating members 2 and 22, surface members 5 and 25 and heat insulating members 8 and 28 respectively and a control section 43. The first and second apparatus bodies 10 and 30 are bent almost in L to be set on a chair or the like to heat a seat part and a back part. Heater parts 3 and 23 are arranged on the undersurface of heater holding members 4 and 24 while a wire pitch B of the heater part 3 is made smaller than the wire pitch C of the heater part 23 so that the heating density of the heating member 2 is larger than the heating density of the heating member 22. In this case, the first apparatus body 10 is set as back part and the second apparatus body 30 as seat part. As a result, the first apparatus body 10 is warmer than the second apparatus body 30 because of a difference in the heating density between the heating members 2 and 22.

Since the detection of the temperature decrease of 3,23 has almost no relation to the presence or absence of the heat equalizing members 48,48, the temperature range in which the energization of the heater sections 3,23 is stopped becomes small, and as a result, the first It becomes easy to bring the instrument body 10 and the second instrument body 30 to desired temperatures.

Next, a modified example of the fourth embodiment will be described with reference to FIGS. 9 and 10.
It will be described based on. This modified example is a soaking member 48, 48
Is provided in a substantially rectangular shape from the overheat protectors 9 and 29 toward the outer circumferential direction of the heat generating members 2 and 22, and as shown in FIG. Even if a part of the main body 30 is covered and the temperature of the covered part rises, the heat is conducted to the overheat preventive device 29 in a short time through the soaking member 48. It is possible to prevent overheating by stopping the energization to 23 and 23.

FIG. 11 shows another modified example, which is a soaking member.
FIG. 12 shows another modified example in which the heat equalizing members 48, 48 are formed in a substantially V shape.
