no. 1 approach

[0032] use Figure 1 to Figure 11 , the heater device according to the first embodiment will be described. The heater device is disposed on a vehicle seat 10 mounted on an automobile. Such as Figure 1 ~ Figure 2 As shown, the vehicle seat 10 includes a seat back 12 for supporting the entire back of the occupant, and a pillow 13 for supporting the back of the occupant's head. Such as image 3 As shown, the seat back 12 is configured such that a cushion material 10 a made of a cushioning material such as polyurethane foam is covered with a surface material such as synthetic leather or fabric.

[0033] Such as figure 1 As shown, the heater device of the present embodiment includes a first planar heater 20A, a second planar heater 20B, a third planar heater 20C, and a fourth planar heater 20D. The first to fourth planar heaters 20A to 20D are arranged on the upper portion of the seat back 12 .

[0034] In addition, the first planar heater 20A and the third planar heater 20C...

no. 2 approach

[0085] use Figure 12 , the heater device of the second embodiment will be described. Such as Figure 10 As shown, the controller 29 of the first embodiment controls the heater temperatures of the first to fourth planar heaters 20A to 20D to be the same. In contrast, as Figure 12 As shown, when the distance between the object and the heat generating part 24 is longer than the second detection distance L2, the control part 29 of the present embodiment controls the second planar heater 20B and the fourth planar heater 20B which are the lower side planar heaters as follows. Heater temperature of the planar heater 20D. That is, the heater temperatures of the second planar heater 20B and the fourth planar heater 20D which are the lower side heaters are controlled to be the same temperature as the first planar heater 20A and the third planar heater which are the upper side heaters. The heater temperature of the shape heater 20C is different.

[0086] The second planar heater 2...

no. 3 approach

[0091] use Figure 13 , the heater device of the third embodiment will be described. In the heater device of the first embodiment described above, the first planar heater 20A and the third planar heater 20C are arranged on the left side in the left-right direction of the seat back 12 , and the second planar heater 20B and the third planar heater The tetrahedral heater 20D is arranged on the right side in the left-right direction of the seat back 12 . On the other hand, in the heater device according to the present embodiment, the fifth planar heater 20E is arranged at the central portion of the seat back 12 in the left-right direction, and the sixth planar heater 20F is arranged at the left-right direction of the pillow 13 . on the central part.

[0092] In this way, the fifth planar heater 20E can be arranged at the center portion of the seat back 12 in the left-right direction, and the sixth planar heater 20F can be arranged at the center portion of the pillow 13 in the le...

Abstract

This heater device for heating the body of a user seated in a seat (10) comprises: a heat generation unit (24) that is disposed in a recess which is recessed from the surface of the seat, and that generates heat via electrical conduction; a distance detection unit (28) that detects the distance between an object around the heat generation unit and the heat generation unit; and a control unit (29) that controls the electrical conduction of the heat generation unit. The control unit comprises: a first control unit (S110, S108) that, when the distance detected by the distance detection unit is greater than an offset distance between the heat generation unit and the surface of the sheet, controls the electrical conduction amount of the heat generation unit such that the output of the heat generation unit is a prescribed output or greater; and a second control unit (S112) that, when the distance detected by the distance detection unit is the offset distance or less, controls the electrical conduction amount of the heat generation unit such that the output of the heat generation unit is less than the prescribed output.

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2019-58596 filed on March 26, 2019, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a heater device for heating the body of an occupant seated on a vehicle seat. Background technique [0004] Conventionally, there is a seat described in Patent Document 1 as a vehicle seat. This seat includes a seat body, a heating member provided on the seat body, and a close contact degree measuring member for measuring the degree of close contact between the seat body and an occupant seated on the seat body. The seat further includes a control means for controlling to reduce the amount of heat output from the heating means as the degree of close contact between the heater body and the occupant increases.
