Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a seat used, for example, in a 71'' seat of an automobile.

(Technical background of the invention and its problems) Conventionally, in this type of automobile front seat, a motor fan is built into the pack rest of the seat body.
The motor fan drives indoor air through the backrest's skin cloth and forcibly blows it out towards the back of the passenger compartment, thereby preventing stuffiness on the back of the human body that contacts the backrest due to the human body's perspiration. There are some things that make it possible to do this.

However, in such a conventional (conventional) one-built Sea I, the indoor air is affected by the temperature and humidity inside the cabin, and it is difficult to maintain a constant temperature and humidity, especially in the summer. 1
7- In a constant temperature and humidity condition where conzoication is effective, the indoor air is adjusted to 20 to 22°C, so
If you have a lot of forced rumors about the motor fan, your body temperature will increase.
The temperature and humidity levels were very troublesome, as I felt cold and easily got sick, and had to keep the airflow to a very small amount.

(Object of the Invention) The present invention is based on the above-mentioned 111 situation.
The purpose of C1 is to provide a sheet that can supply dehumidified and dry air to the contact surface of the human body and adjust the temperature and humidity to an appropriate level.

(Structure of the Invention) In order to achieve the above-mentioned object, the wood is dehumidified and dried by forcing outside air to be drawn in through the surface layer L1 of the part corresponding to the human body contact surface. The feature of this is that the device is built into the seat body.

(Embodiment of the Invention) The present invention will be described in detail below with reference to an illustrated embodiment.

As shown in FIG. 1, reference numeral 1 in the figure represents a seat body used, for example, in front seats for automobiles. Eishi 1~
The main body 1 is composed of a cushion body 2, a backrest 3 which can be tilted forward and backward, and a headrest 4. The headrest 4 has a pair of left and right stays 5 made of pipes. , 6 to the upper end surface of the backrest 3.

As shown in detail in FIGS. 2 to 4, a dehumidifying and drying device 7 is built inside the helad rest 4 of the seat 1 to the main body 1, while the backrest 4 of the backrest 3 An air bag 32 filled with a palm lock 31 is built into the part 3a that comes into contact with the body, and the surface side of the air bag 32 is covered with a skin cloth 33 through which air containing moisture due to sweat from the human body can be breathed. Sewn by. Furthermore, an intake passage 8 and an IJI air passage 9 formed on the left and right edges of the backrest 3 face inside the air bag 32, and dehumidify using the intake passage 8I and the force stay 5 as an air passage. The exhaust passage 9 communicates with the cooling dehumidifier 71 of the drying device 7, and the exhaust passage 9 uses the other stay 6 as a ventilation path.
A damper 10 is provided in the middle of the intake passage 8 to adjust the flow of air, and a damper 10 is provided in the air passage 9 to adjust the air flow. A sirocco fan 11 is installed to avoid forced circulation.

In addition, the above-mentioned dehumidifying and drying device 7 uses the external air around the back of the human body in a state of perspiration ( 32°C, humidity 80%) is taken into the air bag 32 and introduced into the inlet side 71a of the cold iJI dehumidifier 71 through the intake passage 8 and the stay 5.
The outside air is cooled midway through the passage, and the temperature is 15°C and the humidity is 1.
After cooling and dehumidifying uIJ through the cooling dehumidifier 71 (15°C, 100%), it is introduced into the heating dryer 72.
%), the heated dry air is introduced into the air bag 32 again through the other stay 6 and the IJI air passage 9, and is blown out from the epidermis 33 to the outside, that is, to the back side of the human body. It's Shino.

Therefore, 1 above! ζ According to the configuration of the present invention, the dehumidifying/drying device @7 is incorporated inside the headrest 4, and the stay 5.6 that connects the headrest 4 to the backrest 3 is used as the airflow passage. , an air bag 3 provided in a portion 3a of the backrest 3 that corresponds to the human body contact surface.
The outside air from the back of the human body is taken in from 2 through the epidermis 33, cooled and dehumidified, heated and dried, and then exhausted, which simplifies piping and allows for dehumidification and drying inside the headrest, compared to conventional J: Compared to a backrest with a motor fan built into it, it is possible to eliminate the feeling of foreign objects on the backrest surface, and it is also possible to control the temperature and humidity to an appropriate level.

In the embodiment of the present invention, the backrest of the seat body is provided with a suction/exhaust section that dehumidifies and dries the outside air, but the invention is not limited to this, and it may also be provided on the cushion body against which the toe and yaw parts of the human body come into contact. riτ is also good.

(Effects of the Invention) As explained above, the present invention incorporates a dehumidifying and drying device into the headrest of the seat body, takes in and dehumidifies the outside air in the portion corresponding to the human body contact surface, and heats and dries it. It is characterized by a temperature of 25 to 34 degrees Celsius during dehumidification and drying.
Since you can easily control the temperature of about 1 to 30 degrees, you can maintain constant temperature and humidity (even if you are at 13 degrees, your body heat will not be taken away, and your body will stay warm!
! j1 balance can be maintained well, etc.
It has a W-3 effect with excellent practicality.
