Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a seat used, for example, as a front 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 backrest of the seat body, and the motor fan is driven to direct indoor air to the occupant through the skin cloth of the backrest. Some devices are configured to forcefully blow air toward the back of the human body, thereby preventing the back of the human body from getting stuffy due to sweating of the human body, which contacts the backrest.

However, with seats of this conventional structure, the indoor air is affected by the temperature and humidity inside the vehicle, making it impossible to maintain a constant temperature and humidity, especially in summer when the air conditioner is not working. In a constant temperature and humidity state, the indoor air is adjusted to 20 to 22 degrees Celsius, so if there is a large amount of forced air from a motor fan, your body heat will be taken away and you will feel cold, making it easy to get sick, so keep the air flow to a small amount. Must be, etc.
Controlling temperature and humidity was extremely difficult.

《Object of the Invention》 The present invention was made based on the above-mentioned circumstances, and its purpose is to supply dehumidified and dry air to the contact surface of the human body so that the temperature and humidity can be adjusted to an appropriate level. The purpose is to provide seats.

<<Structure of the invention>> In order to achieve the above-mentioned object, the present invention has the following features:
A seat body is constituted by a cushion body, a seat bag, and a headrest, and an air bag is built into the seat body for forcibly inhaling outside air through a skin cloth in a portion corresponding to a portion where the back surface of the human body comes into contact with the seat body; A dehumidifying and drying device that dehumidifies and dries the outside air taken in by the air bag and exhausts it to the back of the human body through the air bag is built into the headrest, and the dehumidifying and drying device and the air bag are communicated with each other through a ventilation path. This is a characteristic feature.

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

As shown in FIG. 1, numeral 1 in the figure is a seat body used, for example, as a front seat for an automobile. The seat body 1 is composed of a cushion body 2, a backrest 3 whose tilt can be adjusted in the front-rear direction, and a backrest 4. The headrest 4 has a pair of left and right stays 5, 6 made of pipe material. It is inserted and attached to the upper end surface portion of the backrest 3 through the holder.

As shown in detail in FIGS. 2 to 4, the head rest 4 of the seat body 1 has a built-in dehumidifying and drying device 7, and the backrest 4 of the seat body 1 comes into contact with the back of the human body. part 3a
An air bag 32 filled with a palm lock 31 is built in, and the surface side of the air bag 32 is sewn with a skin cloth 33 through which air containing moisture due to perspiration from the human body can be breathed. Furthermore, an intake passage 8 and an exhaust passage 9 formed on the left and right edges of the backrest 3 face the inside of the air bag 32, and the intake passage 8 is connected to the dehumidifying and drying device 7 using the one stay 5 as a ventilation passage. The exhaust passage 9 is connected to the cooling dehumidifier 71, and the exhaust passage 9 is connected to the heating dryer 72 of the dehumidifying and drying device 7 using the other stay 6 as a ventilation passage to form a circulation path. A damper 10 is installed along the way to adjust the air flow, and a Shiritzko fan 11 is installed in the exhaust passage 9 to forcefully circulate the air.

That is, the above-mentioned dehumidifying and drying device 7 uses the outside air around the back of the human body in a sweating state (32° C.,
80% humidity) into the air bag 32, and
and the inlet side 7 of the cooling dehumidifier 71 through the stay 5
1a (at this time, the outside air is cooled in the middle of the passage, and the temperature is 15°C and the humidity is 150%), and after being cooled and dehumidified through the cooling dehumidifier 71 (15°C, 100%), The heated dry air is introduced into the heating dryer 72 to be heated and dried (30° C., 50%), and this heated dry air is introduced into the air bag 32 again through the other stay 6 and the exhaust passage 9, and is then passed from the skin cloth 33 to the outside, i.e. It is designed to emit air toward the back of the human body.

Therefore, according to the configuration according to the present invention described above, the dehumidifying drying device 7 is incorporated inside the head rest 4, and the head rest 4 is used as the airflow passage.
The stays 5 and 6 are used to attach the backrest 3 to the backrest 3, and the outside air from the back of the human body is taken in through the skin cloth 33 from the air bag 32 provided on the part 3a of the backrest 3 corresponding to the human body contact surface for cooling, dehumidification, and heating. Since the air is dried and exhausted, piping can be simplified, and dehumidification and drying can be performed inside the headrest, which reduces the feeling of foreign objects on the backrest surface compared to conventional models that incorporate a motor fan inside the backrest. It can be removed and the temperature and humidity can be controlled to an appropriate level.

In the embodiment of the present invention, a suction/exhaust part for dehumidifying and drying outside air is provided on the backrest of the seat body, but the invention is not limited to this, and it may also be provided on the cushion body that the buttocks of the human body comes into contact with.

<<Effects of the Invention>> As explained above, the present invention incorporates a dehumidifying and drying device into the head rest of the seat body to dehumidify the outside air in the area corresponding to the human body contact surface, and heat and dry it before exhausting it. This makes it possible to smooth the sweating action of the human body, prevent stuffiness from occurring, and easily control the temperature between 25 and 34 degrees Celsius during dehumidification and drying. Even in a constant temperature and humidity state, body heat is not lost, and the body's physical condition can be maintained in a good balance, resulting in excellent practical effects.

As a result of the present invention having the dehumidifying and drying device built into the headrest, the air bag built into the backrest can be used in a larger size than when the dehumidifying and drying device is built into the backrest, for example.
It is possible to provide the back crest in such a manner that it abuts many parts of the back of the human body, and even the entire body.
