Abstract

PROBLEM TO BE SOLVED: To comfortably prevent a low temperature burn while forming the interior trim corresponding to the configuration of a chair by fitting a heating wire body in the seat part of the chair and backrest part abutting against the waist to incorporate a heating function. SOLUTION: This chair comprises a seat part 1, a backrest part 2, an armrest part 3 and legs 11, and cusionh materials having a frame and thickness sufficient for the use of the respective parts and the surface thereof are covered with a cover material. A heating wire body 4 is disposed in each part which can be independently electrified and controlled. The heating wire body 4 is disposed on the whole surface of each of the seat part 1 and armrest 3, while being disposed only in a portion of the backrest part 2 abutting against the waist when one is seated on the chair, The deposition of the heating wire body in each part is facilitated by the employment of the heating wire body 4, which can cope with the configuration of each part. Since the heating wire body 4 of the backrest part 2 is dispesed only in the portion of the backrest abutting against the waist, excessive heat to the back is prevented to give a comfortable realistic feeling. The electrification and control are carried out by a controller 8 which has an input cord 9 and plug 10 on the tip thereof to be set AC 10V-24V by a transformer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair having a built-in heat generating function, and is not limited to one person, but can be used by a plurality of people to sit on a chaise longue (sofa) or a chair provided with an armrest or leg rest. It also includes.

[0002]

2. Description of the Related Art Conventionally, various chairs having a built-in heat generating function have been proposed. The heat generating function is provided in the seat, back and armrests of the chair, and is applied to the entire area of each part.

The heat generating function can set the temperature to prevent the temperature from becoming unnecessarily high. However, since the temperature of each part is entirely increased, the backrest part is actually heated. It has been pointed out that it is uncomfortable because it is too much, and there is concern about low temperature burns.

[0004]

In view of the above problems, the present invention is intended to provide a chair which is comfortable and prevents low-temperature burns, and has a built-in heat generating function that can be easily adapted to the shape of the chair. is there.

[0005]

DISCLOSURE OF THE INVENTION The present invention is a chair having a built-in heat generating function characterized by having a line heating element in the seat portion and the lower back portion of the backrest of the chair. The placement unit may also be equipped with a line heating element, and the supply voltage to the line heating element is set to 10V to 24V.

[0006] The line heating element can be easily arranged on each part, and the line heating element is arranged only in the part of the backrest, which corresponds to the waist of the seated person, to avoid irritation to the heat-sensitive back part. ,
Furthermore, by setting the supply voltage to 10 V to 24 V, the effects of eliminating the risk of fire and electric shock and preventing the occurrence of low-temperature burns are achieved.

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a chair having an armrest according to an embodiment, which includes a seat 1, a backrest 2, an armrest 3, and legs 11, each of which has a frame and a thickness sufficient for use. The cushion material and the surface are covered with a cover material.

A wire heating element 4 is disposed inside each part, each part can be independently energized and controlled, and the line heating element has a seat part 1 and an armrest part 3 all over the surface. However, the backrest is provided only in the portion 5 on which the waist rests when sitting.

Energization and control are performed by the controller 8, which has an input cord 9 and a plug 10 at the tip. Further, FIG. 2 is a perspective view showing an embodiment of the leg mounting portion 6, in which the wire heating element 4 is arranged so that it can be energized and controlled.

The voltage supplied to each part is AC by the transformer 7.
The voltage is set to 10 V to 24 V AC, and the wiring has, for example, a two-circuit configuration as shown in FIG. 3, the temperature can be set in two stages by a thermostat (TH), and an overheat prevention thermostat (TB) is provided.

[0010]

As described above, according to the present invention, by adopting the wire heating element, it is possible to easily dispose the wire heating element on each part and to cope with the form of each part of the chair. Further, since the line heating element of the backrest portion is limited to the portion where the waist hits, the effect of preventing excessive heat to the back and making the person feel comfortable is exhibited.

Further, by setting the supply voltage to 10 V to 24 V, it is possible to prevent fire and electric shock, to prevent low-temperature burns, and to ensure safety.
