DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated seat mounted on a seat for heating a seating surface.

[0002]

2. Description of the Related Art FIG. 11 shows a heater unit 1 for heating a seating surface on a seat portion 11 and a back portion 12 of a vehicle seat 10, respectively.
As shown in FIG. 12, the heater unit 16 is provided with a heating element 18 on a support 17 and is connected to a power supply via a wire harness 19 to be supplied with power so that the seating surface of the seat 10 is heated. Is done.

Conventionally, such a heater unit 16 is
As described in Japanese Utility Model Laid-Open Publication No. 60-187635, the heater units 16 are individually configured.
As shown in FIG. 14 and FIG. 14 (a cross-sectional view of the vehicle seat 10), the heater unit 16 includes the main pad 15 and the wadding 1.
It was generally held between four.

[0004] Generally, the heater unit 16 is arranged as shown in FIG.
As shown in FIG. 5, the support 1 coated with the heat welding resin 20
Since the heating element 18 is wired between the support 7b and the support 17a and welded by hot pressing, a support having cushioning properties cannot be used, and the heat-welding resin 20 is further hardened, resulting in a feeling of stiffness and tightness when seated. was there.

[0005] Therefore, the heater unit 16 is provided with a main pad 1 as shown in FIG.
5 and wading 14.

[0006]

Generally, as in the prior art, the thickness between the heater unit and the skin of the seat is 10 to 3 in order to provide cushioning and volume of the skin.
Wadding (pad material) of about 0 mm is used.

[0007] Therefore, the wadding serves as a heat insulating material, which hinders the quick heat property of quickly heating the skin surface of the seat, and it is necessary to increase the power consumption of the heater unit in order to improve the quick heat property.

In addition, the heater unit is individually constructed, and is attached to a main pad surface to be mounted on a seat.
After sewing the wadding on the skin of the seat, it was necessary to further hold the heater unit by sewing or the like.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a heater unit in which a heating element is held in wading.

[0010] Since the heating element can be arranged near the skin of the seat without impairing the cushioning property, the quick heat property can be improved.

Conversely, if the same rapid heating property is obtained, the power consumption of the heater unit can be reduced.

In addition, there is no need to individually configure the heater units, and there is no need to attach a heater unit to the main pad surface or perform a process for attaching the heater unit.

[0013]

The invention according to claim 1 of the present invention comprises a seat pad and a main pad having cushioning properties, a wadding interposed between the skin and the main pad, and a heating element. Since the heating element is held in wadding, it is not necessary to separately configure the heater unit, the quick heat can be improved without impairing the cushioning property and the volume feeling of the skin, and the step of mounting the heater unit is not required.

According to the second aspect of the present invention, the heating element is sewn and held on the wadding, and a heater unit can be configured without using a dedicated member for holding the heating element.

According to a third aspect of the present invention, the heating element is bonded and held to the wadding, so that a heater unit can be constituted regardless of the thickness and material of the wadding.

According to the fourth aspect of the present invention, the heating element portion and wadding can be individually configured, and the heating element portion and wadding can be separated.

According to the fifth aspect of the present invention, the heating element is disposed on the skin side of the wadding, so that the quick heat property can be further improved.

According to a sixth aspect of the present invention, the heating element is arranged on the main pad side of the wadding, so that the cushioning property and the durability of the heating element can be further improved.

According to a seventh aspect of the present invention, the wadding is divided, and the heating element is disposed between the divided waddings. The heater has a cushioning property, a rapid heating property, and durability of the heating element. Unit can be configured.

The invention according to claim 8 has a base cloth material on the front surface or the back surface of the wadding, so that the holding power of the heating element can be increased and the durability can be improved.
