  In the seat heater described in Patent Document 1, with respect to the temperature control means (controller), the heater is energized by providing a sensor on a tape member disposed on the sheet surface. However, in such a seat, for example, when the vehicle is traveling, the frequency of movement of the seated person is high, and a large load is applied to the seat at that time, so that the sensor provided on the seat surface portion is easily damaged. There was an inconvenience.

  Further, in the seat heater described in Patent Document 2, the end of the heating wire is drawn out of the seat and connected to the battery and the operation switch outside. And the structure regarding the operation control means which controls On / Off of a seat heater like a battery and an operation switch is disclosed.

  However, Patent Document 2 does not describe a configuration related to temperature control means for heating wires, such as a thermistor. In general, the temperature control means is disposed on the seat surface (the area where the seated person is seated and between the skin material and the cushion material), so that not only the seated person is loaded and easily damaged, but also the seating When a person sits on a seat provided with a seat heater, there is an inconvenience that unevenness occurs and the seating feeling is not good.

  An object of the present invention is to provide a seat provided with a highly safe seat heater that is less likely to damage the temperature control means of the seat heater even when a seated person is loaded. Another object of the present invention is to provide a seat provided with a seat heater that eliminates the uncomfortable feeling at the time of sitting due to the provision of the seat heater.

  According to the seat provided with the seat heater according to claim 1, the sheet-like base material, the heater wire fixed to the base material, and the temperature control means for controlling the temperature of the heater wire are provided on the cushion material. Is a seat formed by covering with a skin material, the cushion material is a seat surface portion on which a seated person sits, and a recess formed on a surface opposite to the seat surface portion, The seat heater includes: a seat surface side arrangement portion disposed on the seat surface portion; and a heater wire extension portion extending from the seat surface side heater wire disposed on the seat surface side arrangement portion. And at least a part of the temperature control means is connected to the heater wire extension and disposed in the recess of the cushion material.

Generally, in a seat provided with a seat heater, the seat heater is disposed on a cushion material and on the seating surface side of the seated person, that is, on the seat surface portion of the cushion material. According to the prior art, the temperature control means of the seat heater is disposed on the seat surface portion integrally with the heater portion. As a result, the load of the seated person is applied to the temperature control means, and there is a problem that the connecting portion between the temperature control means and the heater wire and the temperature control means are easily damaged.
On the other hand, in the seat provided with the seat heater of the present invention, the seat heater includes a heater wire extending from the seat surface side arrangement portion in addition to the seat surface side arrangement portion arranged at the position where the seated person sits. Has an extension. Since the heater wire extension is connected to the temperature control means, the temperature control means is located at the position where the seated person's buttocks do not contact, that is, the position below the seat surface, more specifically, in the recess provided in the cushion material. It is possible to arrange in. Therefore, it is difficult for the temperature control means to directly receive the load of the seated person. Further, since the temperature control means is disposed in the concave portion, the seat heater does not receive a buffer from the surface on the side where the seated person abuts, that is, the surface opposite to the seat surface portion. Hard to damage.
Furthermore, by disposing the temperature control means in the recess, spatial restrictions are suppressed and the space saving performance is high.
Further, since the temperature control means is disposed at a position other than the position where the seated person is seated, there is no sense of incongruity due to the temperature control means coming into contact with the seated person's body (buttock or waist). Therefore, a seat with a good seating feeling can be provided.

At this time, it is preferable that the cushion material includes a hole portion penetrating in the thickness direction of the cushion material, and the heater wire extension portion is inserted through the hole portion.
