Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile seat that cools or heats a seated person in a contact manner by supplying cold or warm air from an air conditioner to a seat cushion and a seat bag.

When cooling or heating the inside of a car, it is faster to cool or heat the interior of a car by directing the cold or warm air to the body of the occupant, rather than by sending cold or warm air into the car to cool or warm the atmosphere inside the car. In recent years, attempts have been made to cool or heat the human body by sending cold or warm air to the seat cushion and seat bag, since the heating rate is high, it is effective, and there is little loss of power. The seat used for such cooling or heating has hollow parts formed in the lower part of the seat cushion and the back part of the seat cushion, respectively, and hollow parts in the pad material of the upper part of the seat cushion and the front part of the seat back that come into contact with the seated person. A plurality of small-diameter ventilation holes are drilled to communicate with the cavity, and the cavity is also communicated with a duct of an air conditioner installed in the automobile, so that cold or warm air from the air conditioner is After being supplied to the cavity, it flows out through the ventilation hole and fills the space between the seat skin and the padding material, thereby uniformly cooling or warming the body of the seated person. However, uniformly cooling parts such as the lower back and coccyx of the human body in the same manner as other parts not only causes discomfort to the human body, but also causes discomfort to the human body.
This is undesirable because it is harmful to health, and conventional sheets have had practical drawbacks.

The present invention eliminates the drawbacks of seats that perform contact cooling or heating, and provides an automobile seat that can switch between cooling or heating (especially cooling) with a simple configuration. The cavity formed in the lower part of the seat cushion and the back of the seat back communicates with the duct of the air conditioner, and a plurality of ventilation holes are bored in the padding material of the upper part of the seat cushion and the front part of the seat back. In a seat that performs contact cooling or heating by introducing cool air or warm air, the hollow portion is divided into at least two parts, and each divided chamber is connected to a duct of an air conditioner, and at least one divided chamber is connected to the air conditioner. It is characterized by a valve attached to the inlet that automatically opens and closes at a predetermined temperature.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of one embodiment of the present invention, showing the case of a seat cushion 1. FIG. This seat cushion 1 is made of foamed polyurethane resin and integrally molded to form a pad material, and the pad material in the upper part of the cushion 1 is provided with a plurality of ventilation holes 2, 2... that pass through it vertically. At the same time, a cavity is formed in the lower part to introduce cold or warm air. This cavity is divided into two in the front and back to form a front divided chamber 3 and a rear divided chamber 4, and the lower part of each divided chamber 3 and 4 is opened to allow inlets 5 and 6 for cold air or warm air. is formed. In this case, the rear divided chamber 4 is located at the coccyx of the seated person, and the front divided chamber 3 is located at the foot.

Note that 12, 12, . . . are springs that are stretched vertically or horizontally within the seat cushion 1 and support the pad material.

The tip of the duct 7 connected to the air conditioner (not shown) is branched into each divided chamber 3,
4 is connected to the inlets 5 and 6 of the
Each of the divided chambers 3 and 4 is connected to an air conditioner. A valve 8 is attached to the inlet 6 of the rear divided chamber 4, and the valve 8 cuts off communication with the air conditioner when the temperature is below a predetermined temperature. For example, as shown in FIG. 2, this valve 8 is composed of a bimetal 9 and a shutter 11 which is formed so that one end engages with the bimetal 9 and is rotatable about a pivot pin 10. 11 is adapted to close and open the entrance 6 of the rear divided chamber 4. That is, when the temperature exceeds a predetermined temperature, the bimetal 9 bends and rotates the shutter 11 clockwise, opening the inlet 6 as shown in FIG. Below (for cooling),
The bimetal 9 becomes linear, thereby causing the shutter 11 to rotate counterclockwise.
As shown in FIG. 4B, the entrance 6 is closed. Due to this sealing, cold air is not supplied to the rear divided chamber 4, and the pad material is not cooled, so that no discomfort is caused to the human body.

The above configuration is installed not only in the seat cushion but also in the seat bag to cool and heat the seat. In the case of the seat bag 13, the cavity is divided into upper and lower halves, and the valve 8
is placed in the lower divided chamber.

According to this embodiment configured in this way, since the supply of cold air or warm air to the divided compartments is adjusted by the valve, the pad material of the divided compartments corresponding to the parts that are not desirable to be cooled is There is no cooling and there is no adverse effect on the human body. Further, since this valve can be operated automatically, it is convenient and does not bother the seated person.

In the present invention, the cavity may be divided into two or more parts to enable fine adjustment, and the valves may be attached to the entrances of each of the divided chambers. Furthermore, this valve is not limited to bimetal, and other temperature-sensitive materials, temperature sensors, etc. may be used as long as it operates at a predetermined temperature.

As described above in detail, according to the present invention, it is possible to adjust cold air or warm air to parts of the human body where cooling or heating is not desirable with a simple configuration, thereby providing a healthy car seat. becomes possible.
